This file is free documentation; the Free Software Foundation gives unlimited permission to copy, distribute and modify it. Basic Installation ================== Briefly, the shell commands `./configure; make; make install' should configure, build, and install this package. The following more-detailed instructions are generic; see the `README' file for instructions specific to this package. The `configure' shell script attempts to guess correct values for various system-dependent variables used during compilation. It uses those values to create a `Makefile' in each directory of the package. It may also create one or more `.h' files containing system-dependent definitions. Finally, it creates a shell script `config.status' that you can run in the future to recreate the current configuration, and a file `config.log' containing compiler output (useful mainly for debugging `configure'). It can also use an optional file (typically called `config.cache' and enabled with `--cache-file=config.cache' or simply `-C') that saves the results of its tests to speed up reconfiguring. Caching is disabled by default to prevent problems with accidental use of stale cache files. If you need to do unusual things to compile the package, please try to figure out how `configure' could check whether to do them, and mail diffs or instructions to the address given in the `README' so they can be considered for the next release. If you are using the cache, and at some point `config.cache' contains results you don't want to keep, you may remove or edit it. The file `configure.ac' (or `configure.in') is used to create `configure' by a program called `autoconf'. You need `configure.ac' if you want to change it or regenerate `configure' using a newer version of `autoconf'. The simplest way to compile this package is: 1. `cd' to the directory containing the package's source code and type `./configure' to configure the package for your system. Running `configure' might take a while. While running, it prints some messages telling which features it is checking for. 2. Type `make' to compile the package. 3. Optionally, type `make check' to run any self-tests that come with the package. 4. Type `make install' to install the programs and any data files and documentation. 5. You can remove the program binaries and object files from the source code directory by typing `make clean'. To also remove the files that `configure' created (so you can compile the package for a different kind of computer), type `make distclean'. There is also a `make maintainer-clean' target, but that is intended mainly for the package's developers. If you use it, you may have to get all sorts of other programs in order to regenerate files that came with the distribution. 6. Often, you can also type `make uninstall' to remove the installed files again. Compilers and Options ===================== Some systems require unusual options for compilation or linking that the `configure' script does not know about. Run `./configure --help' for details on some of the pertinent environment variables. You can give `configure' initial values for configuration parameters by setting variables in the command line or in the environment. Here is an example: ./configure CC=c99 CFLAGS=-g LIBS=-lposix *Note Defining Variables::, for more details. Compiling For Multiple Architectures ==================================== You can compile the package for more than one kind of computer at the same time, by placing the object files for each architecture in their own directory. To do this, you can use GNU `make'. `cd' to the directory where you want the object files and executables to go and run the `configure' script. `configure' automatically checks for the source code in the directory that `configure' is in and in `..'. With a non-GNU `make', it is safer to compile the package for one architecture at a time in the source code directory. After you have installed the package for one architecture, use `make distclean' before reconfiguring for another architecture. Installation Names ================== By default, `make install' installs the package's commands under `/usr/local/bin', include files under `/usr/local/include', etc. You can specify an installation prefix other than `/usr/local' by giving `configure' the option `--prefix=PREFIX'. You can specify separate installation prefixes for architecture-specific files and architecture-independent files. If you pass the option `--exec-prefix=PREFIX' to `configure', the package uses PREFIX as the prefix for installing programs and libraries. Documentation and other data files still use the regular prefix. In addition, if you use an unusual directory layout you can give options like `--bindir=DIR' to specify different values for particular kinds of files. Run `configure --help' for a list of the directories you can set and what kinds of files go in them. If the package supports it, you can cause programs to be installed with an extra prefix or suffix on their names by giving `configure' the option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. Optional Features ================= Some packages pay attention to `--enable-FEATURE' options to `configure', where FEATURE indicates an optional part of the package. They may also pay attention to `--with-PACKAGE' options, where PACKAGE is something like `gnu-as' or `x' (for the X Window System). The `README' should mention any `--enable-' and `--with-' options that the package recognizes. For packages that use the X Window System, `configure' can usually find the X include and library files automatically, but if it doesn't, you can use the `configure' options `--x-includes=DIR' and `--x-libraries=DIR' to specify their locations. Specifying the System Type ========================== There may be some features `configure' cannot figure out automatically, but needs to determine by the type of machine the package will run on. Usually, assuming the package is built to be run on the _same_ architectures, `configure' can figure that out, but if it prints a message saying it cannot guess the machine type, give it the `--build=TYPE' option. TYPE can either be a short name for the system type, such as `sun4', or a canonical name which has the form: CPU-COMPANY-SYSTEM where SYSTEM can have one of these forms: OS KERNEL-OS See the file `config.sub' for the possible values of each field. If `config.sub' isn't included in this package, then this package doesn't need to know the machine type. If you are _building_ compiler tools for cross-compiling, you should use the option `--target=TYPE' to select the type of system they will produce code for. If you want to _use_ a cross compiler, that generates code for a platform different from the build platform, you should specify the "host" platform (i.e., that on which the generated programs will eventually be run) with `--host=TYPE'. Sharing Defaults ================ If you want to set default values for `configure' scripts to share, you can create a site shell script called `config.site' that gives default values for variables like `CC', `cache_file', and `prefix'. `configure' looks for `PREFIX/share/config.site' if it exists, then `PREFIX/etc/config.site' if it exists. Or, you can set the `CONFIG_SITE' environment variable to the location of the site script. A warning: not all `configure' scripts look for a site script. Defining Variables ================== Variables not defined in a site shell script can be set in the environment passed to `configure'. However, some packages may run configure again during the build, and the customized values of these variables may be lost. In order to avoid this problem, you should set them in the `configure' command line, using `VAR=value'. For example: ./configure CC=/usr/local2/bin/gcc causes the specified `gcc' to be used as the C compiler (unless it is overridden in the site shell script). Unfortunately, this technique does not work for `CONFIG_SHELL' due to an Autoconf bug. Until the bug is fixed you can use this workaround: CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash `configure' Invocation ====================== `configure' recognizes the following options to control how it operates. `--help' `-h' Print a summary of the options to `configure', and exit. `--version' `-V' Print the version of Autoconf used to generate the `configure' script, and exit. `--cache-file=FILE' Enable the cache: use and save the results of the tests in FILE, traditionally `config.cache'. FILE defaults to `/dev/null' to disable caching. `--config-cache' `-C' Alias for `--cache-file=config.cache'. `--quiet' `--silent' `-q' Do not print messages saying which checks are being made. To suppress all normal output, redirect it to `/dev/null' (any error messages will still be shown). `--srcdir=DIR' Look for the package's source code in directory DIR. Usually `configure' can determine that directory automatically. `configure' also accepts some other, not widely useful, options. Run `configure --help' for more details. ctemplate-ctemplate-2.3/Makefile.am000066400000000000000000000620761231237053300173560ustar00rootroot00000000000000## Process this file with automake to produce Makefile.in # Make sure that when we re-make ./configure, we get the macros we need ACLOCAL_AMFLAGS = -I m4 # This is so we can #include AM_CPPFLAGS = -I$(top_srcdir)/src # These are good warnings to turn on by default if GCC AM_CXXFLAGS = -Wall -Wwrite-strings -Woverloaded-virtual -Wno-sign-compare endif # mingw does weird directory munging on /tmp, which causes some of our # tests to fail, so use a different tmpdir there. if MINGW TMPDIR = ./ else TMPDIR = /tmp endif ctemplateincludedir = $(includedir)/ctemplate ## The .h files you want to install (that is, .h files that people ## who install this package can include in their own applications.) ## We have to include both the .h and .h.in forms.

Fixed some more C++11 issues. Removed deprecated Template::SetEscapedValueAndShowSection() and Template::ReloadIfChanged(). == 18 April 2012 == Ctemplate 2.2 has been released. Several issues reported by G++ 4.7 have been fixed. == 22 March 2012 == 2.1 has been released. operator[] has been added to TemplateDictionary. == 24 January 2012 == I've just released ctemplate 2.0. It has no functional changes from ctemplate 1.2. The `google-ctemplate` project has been renamed to `ctemplate`. I (csilvers) am stepping down as maintainer, to be replaced by Olaf van der Spek. Welcome to the team, Olaf! I've been impressed by your contributions to the project discussions and code to date, and look forward to having you on the team. I bumped the major version number up to 2 to reflect the new community ownership of the project. All the [http://google-ctemplate.googlecode.com/svn/tags/ctemplate-2.0/ChangeLog changes] are related to the renaming. === 18 January 2011 === The `google-ctemplate` Google Code page has been renamed to `ctemplate`, in preparation for the project being renamed to `ctemplate`. In the coming weeks, I'll be stepping down as maintainer for the ctemplate project, and as part of that Google is relinquishing ownership of the project; it will now be entirely community run. The name change reflects that shift. === 22 December 2011 === I've just released ctemplate 1.1. The only functionality change is obscure: when a reload is done (via, say, `ReloadAllIfChanged`), and a new file has been created since the last reload that both a) has the same filename as a template file that had been loaded in the past, and b) is earlier on the template search-path than the previously loaded file, *and* c) the previously loaded file hasn't changed since the last reload, then at reload-time we now load the new file into the template, replacing the old file. Before we would only load the new file if the old file had changed on disk, and would otherwise leave the template alone. Even more minor changes are in the [http://google-ctemplate.googlecode.com/svn/tags/ctemplate-1.1/ChangeLog ChangeLog]. === 26 August 2011 === I've just released ctemplate 1.0! (I've decided 4 weeks is well within the definition of "the next week or so"...) A bit anti-climactic: there are no changes from ctemplate 1.0rc2. === 29 July 2011 === I've just released ctemplate 1.0rc2. This fixes a serious bug where I had added #includes in installed header files, that tried to include non-installed header files. This means it was impossible to use installed ctemplate; it only worked if you were using it from the tarball directory. I also fixed the unittest that was supposed to catch this, but didn't (it was also building in the tarball directory). If no further problems are found in the next week or so, I will release ctemplate 1.0. === 22 July 2011 === I've just released ctemplate 1.0rc1. If no problems are found in the next week or two, I will release ctemplate 1.0. ctemplate 1.0rc1 has relatively few changes from ctemplate 0.99. xml-escaping has been improved a bit. A couple of bugs have been fixed, including one where we were ignoring template-global sections (a relatively new feature) in some places. A full list of changes is available in the [http://google-ctemplate.googlecode.com/svn/tags/ctemplate-1.0rc1/ChangeLog ChangeLog]. I've also changed the internal tools used to integrate Google-supplied patches to ctemplate into the opensource release. These new tools should result in more frequent updates with better change descriptions. They will also result in future ChangeLog entries being much more verbose (for better or for worse). === 24 January 2011 === I've just released ctemplate 0.99. I expect this to be the last release before ctemplate 1.0. Code has settled down; the big change here is some efficiency improvements to javascript template escaping. There is also a bugfix for an obscure case where ReloadAllIfChanged() is used with multiple ctemplate search paths, where files are deleted in one part of the search path between reloads. Unless you need either of the above, there's no particular reason to upgrade. A full list of changes is available in the [http://google-ctemplate.googlecode.com/svn/tags/ctemplate-0.99/ChangeLog ChangeLog]. === 23 September 2010 === I've just released ctemplate 0.98. The changes are settling down as we approach ctemplate 1.0 -- a few new default modifiers, a few performance tweaks, a few portability improvements, but nothing disruptive. In my testing for this release, I noticed that the template regression test (but not other template tests) would segfault on gcc 4.1.1 when compiled with -O2. This seems pretty clearly to be a compiler bug; if you need to use gcc 4.1.1 to compile ctemplate, you may wish to build via `./configure CXXFLAGS="-O1 -g"` just to be safe. === 20 April 2010 === I've just released ctemplate 0.97. This change consists primarily of a significant change to the API: the addition of the `TemplateCache` class, combined with deprecation of the `Template` class. `TemplateCache` is a class that holds a collection of templates; this concept always existed in ctemplate, but was not previously exposed. Many static methods of the `Template` class, such as `ReloadAllIfChanged()`, have become methods on `TemplateCache` instead (the `Template` methods have been retained for backwards compatibility.) Other methods, such as `Expand()`, have become free functions. In fact, the entire `Template` class has been deprecated. The deprecation of `Template` calls for changes in all clients of the template code -- you can see in the example at the top of this page how the code has changed from `Template* tpl = ctemplate::Template::GetTemplate("example.tpl", ctemplate::DO_NOT_STRIP); tpl->Expand(&output, &dict);` to `ctemplate::ExpandTemplate("example.tpl", ctemplate::DO_NOT_STRIP, &dict, &output);`. These changes will make the code simpler and more thread-safe. Old code should continue to work -- the `Template` class remains -- but new code should use the new API, and old code should transition as convenient. One old API method is intrinsically thread-unsafe, and should be prioritized to change: `tpl->ReloadIfChanged` should change to `ctemplate::Template::ReloadAllIfChanged()`. Note this is a semantic change: all templates are now reloaded, rather than just one. However, since templates are reloaded lazily, and only if they've changed on disk, I'm hopeful it will always be a reasonable change to make. To go along with these changes, the documentation has been almost entirely revamped and made more accessible. Obscure ctemplate features have been excised from the user's guide and moved into a separate reference document. The new API is fully documented, including new flexibility around reloading templates, made available by the introduction of `TemplateCache`. There are some more minor changes as well, such as the addition of #include guards in the auto-generated .tpl.h files, to make it safe to multiply-include them. I've also been continuing the portability work: ctemplate should now work under Cygwin and MinGW. A full list of changes is available in the [http://google-ctemplate.googlecode.com/svn/tags/ctemplate-0.97/ChangeLog ChangeLog]. I know I've said this before, but I don't expect major API changes before the 1.0 release. The most significant changes I expect to see are the potential removal of some of the 'forwarding' methods in the (deprecated) `Template` class. === 12 June 2009 === I've just released ctemplate 0.95. This is entirely an API cleanup release. Actually, relatively little of the API proper has changed: `StringToTemplate` no longer takes an autoescape-context arg (instead you specify this as part of the template-string, using the `AUTOESCAPE` pragma). A few obsolete constructs have gone away, such as the `TemplateFromString` class and `TemplateDictionary::html_escape` and friends (just use the top-level `html_escape`). See the [http://google-ctemplate.googlecode.com/svn/tags/ctemplate-0.95/ChangeLog ChangeLog] for a full list of these changes. The biggest change is a renaming: the default namespace is now `ctemplate` rather than `google`, and the include directory is `ctemplate` rather than `google`. Other namespaces, such as `template_modifiers`, have gone away. All these changes will require you to modify your old code to get it working with ctemplate 0.95. I've written a [http://google-ctemplate.googlecode.com/svn/trunk/contrib/convert_to_95.pl script] to help you do that. Please open an [http://code.google.com/p/google-ctemplate/issues/list issue] if you see a problem with the script. I've tested it, but not as widely as I'd like. Also note the script will not be perfect for more complex constructs, which you will have to clean up by hand. I hope (expect) the API is now stable, and we won't see any more such changes before ctemplate 1.0. I tried to isolate them all in this release; except for the API changes, this release should behave identically to ctemplate 0.94. === 7 May 2009 === I've just released ctemplate 0.94. A few new features have been added, such as the ability to expand a template into your own custom `ExpandEmitter` instance, and the ability to hook the annotation system (typically used for debugging). You can now remove strings from the template cache in addition to adding them. Also, there continues to be a trickle of new modifiers, in this case a modifier for URL's in a CSS context. However, the most invasive changes were made for speed reasons. The biggest is that (almost) all `TemplateDictionary` allocations are now done on the arena -- this includes allocations by the STL classes inside the dictionary. This allows us to free all the memory at once, rather than item by item, and has yielded a 3-4% speed improvement in our tests. I've combined this with a `small_map` class that stores items in a vector instead of a hash-map until we get to 3 or 4 items; this gives another speed increase in the (common) case a template has only a few sections or includes. I also changed the hashing code to use [http://murmurhash.googlepages.com/ MurmurHash] everywhere, rather than the string hash function built into the STL library. This should be faster. All these changes should not be outwardly visible, but they do use more advanced features of C++ than ctemplate has to date. This may result in some problems compiling, or conceivably when running. If you see any, please file an [http://code.google.com/p/google-ctemplate/issues/list issue report]. You can see a full list of changes on the [http://google-ctemplate.googlecode.com/svn/tags/ctemplate-0.94/ChangeLog ChangeLog]. === 20 August 2008 === ctemplate 0.91 introduces the beginning of some API changes, as I look to clean up the API in preparation for ctemplate 1.0. After 1.0, the API will remain backwards compatible, but until that time, the API may change. Please take a look at the [http://google-ctemplate.googlecode.com/svn/trunk/ChangeLog ChangeLog] to see if any of these changes affect you. One change is the introduction of a new `PerExpandData` class, which holds some state that was formerly in the `TemplateDictionary` class. I'm still not sure if this class is a good idea, if it should be separate from `TemplateDictionary` or a member, or what functionality should move there (for instance, should `SetTemplateGlobal` move there, since template-global variables are really, in some sense, per-expand variables?) If you have any feedback, ideally based on your own experience using the current API, feel free to post it at `google-ctemplate@googlegroups.com`. ctemplate also has several new features, including the addition of "separator" sections, and the ability to change the markup character (from `{{`). See the [http://google-ctemplate.googlecode.com/svn/trunk/ChangeLog ChangeLog] for a complete list, and the [http://google-ctemplate.googlecode.com/svn/trunk/doc/howto.html howto documentation] for more details on these new features. ctemplate-ctemplate-2.3/README000066400000000000000000000027401231237053300161720ustar00rootroot00000000000000See the documentation in the doc/ directory for information about how to use the ctemplate library. COMPILING --------- To compile test applications with these classes, run ./configure followed by make. To install these header files on your system, run 'make install'. (On Windows, the instructions are different; see README.windows.) See INSTALL for more details. This code should work on any modern C++ system. It has been tested on Linux (Ubuntu, Fedora, RedHat), Solaris 10 x86, FreeBSD 6.0, OS X 10.3 and 10.4, and Windows under both VC++7 and VC++8. There are a few Windows-specific details; see README.windows for more information. CTEMPLATE AND THREADS --------------------- The ctemplate library has thread support, so it works properly in a threaded environment. For this to work, if you link libraries with -lctemplate you may find you also need to add -pthread (or, on some systems, -pthreads, and on others, -lpthread) to get the library to compile. If you leave out the -pthread, you'll see errors like this: symbol lookup error: /usr/local/lib/libctemplate.so.0: undefined symbol: pthread_rwlock_init If your code isn't multi-threaded, you can instead use the ctemplate_nothread library: -lctemplate_nothreads To summarize, there are two ways to link in ctemlpate in non-threaded applications. For instance: 1) gcc -o my_app my_app.o -lctemplate -pthread 2) gcc -o my_app my_app.o -lctemplate_nothreads If your application uses threads, you should use form (1). ctemplate-ctemplate-2.3/README_windows.txt000066400000000000000000000040471231237053300205640ustar00rootroot00000000000000This project has been ported to Windows. A working solution file exists in this directory: ctemplate.sln You can load this solution file into either VC++ 7.1 (Visual Studio 2003) or VC++ 8.0 (Visual Studio 2005) -- in the latter case, it will automatically convert the files to the latest format for you. When you build the solution, it will create libctemplate.dll, the main library for this project, plus a number of unittests, which you can run by hand (or, more easily, under the Visual Studio debugger) to make sure everything is working properly on your system. The binaries will end up in a directory called "debug" or "release" in the top-level directory (next to the .sln file). I don't know very much about how to install DLLs on Windows, so you'll have to figure out that part for yourself. If you choose to just re-use the existing .sln, make sure you set the IncludeDir's appropriately! Look at the properties for libctemplate.dll. If you wish to link to ctemplate statically instead of using the .dll, you can; see the example project template_unittest_static. For this to work, you'll need to add "/D CTEMPLATE_DLL_DECL=" to the compile line of every ctemplate .cc file. Note that these systems are set to build in Debug mode by default. You may want to change them to Release mode. Currently, Template::StringToTemplate returns a Template object that you, the caller, must free. We've heard reports that Windows can have trouble allocating memory in a .dll that is meant to be freed in the application. Thus, we suggest you not use StringToTemplate from Windows. Instead, you can use Template::StringToTemplateCache() followed by Template::GetTemplate(). I have little experience with Windows programming, so there may be better ways to set this up than I've done!

My text editor is vim. Here is a little gift for other people like me. Howto have google-ctemplate colored by vim : In your home directory, run 'sh $0'. Now restart vim. This will autodetects file with tpl extension and colors them. You can change the color by changing the HiLink lines ( try changing String by Identifier ) . I'm not sure exactly about what are the legal marker names. Feel free to change the regexes. I only tryed this with vim 6.4 , I just cut and past the things about version checking.

Guide to using Auto Escape

Introduction

Auto Escape is an optional mode of execution in the Template System developed to provide a better defense against cross-site scripting (XSS) in web applications. In this mode, the Template System assumes responsibility for applying the proper escaping modifiers for each variable in your template (and templates it may include). As such, the template developer no longer needs to manually apply escaping modifiers to each variable, a process which is repetitive and error-prone particularly in larger and more complex applications.

In order for the Template System to properly determine the escaping modifiers to apply to variables, it activates a built-in HTML-aware parser during template initialization. The parser scans the template to determines the context in which each variable is being emitted. The scanning is performed at initialization-time only hence does not contribute to processing costs at template expansion time.

Refer to Security Considerations for additional security information on escaping directives and their use according to the context in which content is being expanded.

Current Status

Auto Escape currently supports well HTML and Javascript templates. It also provides very basic support for CSS, JSON and XML templates where it applies the corresponding escaping modifier but without utilizing a parser. We may in the future provide parsers specific to these contexts and modifiers for them that are finer-grained.

Overview

This section provides more background on Auto Escape. Refer to How to Auto Escape for information on how to leverage this mode in your application.

Using template modifiers

In the simplest case, where you only want to use template-modifiers to achieve html-safety (that is, you only use html_escape, url_query_escape, and so forth), you can stop specifying template-modifiers in your template at all. The Auto Escape mode will generate the modifiers on its own and perform the correct escaping.

If you need other types of modifiers, including your own custom modifiers, you can still specify them in your template and they will continue to work just the same. The Auto Escape mode will simply apply the appropriate escaping modifiers after your own.

Other reasons for manually specifying variable modifiers include:

  1. To indicate a variable is safe. You may add the :none modifier as the last modifier for a given variable, in which case the Auto Escape mode will leave it untouched and not apply escaping directives to it. Use only when you are sure the variable is trusted to be safe from XSS.
  2. To select a different escaping modifier from a list of equivalent modifiers. Certain modifiers are equivalent from an escaping point of view in that they would all ensure given content is safe when escaped in a specific context. The Auto Escape mode choses the most common escaping modifier for that use but allows you to indicate a different choice as shown below:
    TemplateContextPrimary Modifier Accepted alternatives
    TC_HTML :html_escape
    • :pre_escape
    • :html_escape_with_arg=snippet
    • :html_escape_with_arg=attribute
    • :html_escape_with_arg=url
    • :url_query_escape
    • :url_escape_with_arg=html
    • :img_src_url_escape_with_arg=html
    TC_HTML and TC_CSS :cleanse_css
    • :url_escape_with_arg=css
    • :img_src_url_escape_with_arg=css
    TC_XML :xml_escape
    • :html_escape
    • :html_escape_with_arg=attribute
    TC_JS :javascript_escape
    • :url_escape_with_arg=javascript
    • :img_src_url_escape_with_arg=javascript
    TC_JSON :javascript_escape
    • :json_escape
  3. To add additional escaping modifiers. The Template System will never remove escaping directives you explicitly specify.

Escaping Contexts

The table belows indicates which modifier Auto-Escape selects to escape a given variable, based on the context of the variable being inserted and, possibly, on more specific information such as whether the variable is inside quotation marks. The table only applies for the well-supported TemplateContext values (currently TC_HTML and TC_JS).

In a few cases, we do not have a modifier that is both safe against XSS and respecting of the semantics of the variable therefore we fail the template initialization. An error is logged indicating the cause of the failure.

Comments:

  • For values of URL-accepting attributes, we apply a different modifier if the variable is at the beginning of the attribute value or not because in the former case we consider the variable to represent a complete URL and hence also check that its scheme is safe (HTTP or HTTPS).
  • We recommend that you enclose attribute values in quotes in particular:
    1. Under some conditions outlined in the table above, when variables are present in attribute values that are not enclosed in quotes, we may fail template initialization because we do not have escaping modifiers that are safe to use.
    2. Also the determination of which escaping modifier to apply for unquoted attribute values specifically is likely to change in the future.

The Auto Escape mode is designed to be simple to use and to produce correct correct escaping with minimal input. It does however come with restrictions governing the use of this template system.

Limitations

  • Templates may only be included in regular HTML text. Including a template within HTML comments or inside an HTML tag is currently not supported. In the example below, HEADER and FOOTER are properly included but TAG and COMMENT are not.

              <html><head>{{>HEADER}}</head><body>
          <{{>TAG}}>
          <p>
          <!-- {{>COMMENT}} -->
          <p>{{>FOOTER}}
          </body></html>

    If the template system detects that you are including a template in another HTML context, it will log a warning.

  • Included templates may not cross HTML boundaries. They cannot start with one TemplateContext and end in another. For example, the template below crosses boundaries -- it starts in HTML and ends in Javascript -- and is therefore not a valid included template for auto-escaping.

            <html>
          <head>
          </head>
          <body>
            Hello USER.
              <script>
                 var a = 'not a nice template';

    To rectify this violation, continue the template by completing the javascript code and terminating it with a </script> tag.

  • Error reporting. We currently report errors by logging a warning or an error during initial template initialization and parsing if we suspect something is incorrect. Please check for them, as they indicate an error that may cause auto-escaping to work improperly.

  • Beware of double escaping. When you use the Auto Escape mode, you surrender all variable escaping to the template system. If you also perform your own escaping in your source code, you may face situations where content was escaped multiple times.

    In particular, do not use any of the legacy methods below or others that perform variable escaping.

    • SetEscapedValue
    • SetEscapedFormatttedValue
    • SetEscapedValueAndShowSection

  • Supported HTML contexts. HTML (TC_HTML) and Javascript (TC_JS) templates are well supported. Other template contexts have only basic support. For these contexts, variables are escaped as follows:

    TemplateContextEscaping Applied
    TC_JSON :javascript_escape
    TC_XML :xml_escape
    TC_CSS :cleanse_css

  • New restrictions on the use of BI_SPACE and BI_NEWLINE. These system variables may not be re-assigned to a semantically different value via dict->SetValue or related methods, and they may not have modifiers attached to them in templates. For instance: it's ok to redefine BI_NEWLINE from \n to \r\n, since html treats them identically. But changing it to hello, world! is not allowed.

A new filename convention

The Auto Escape feature codifies simple conventions of template filenames:

  1. CSS templates optionally include, in their filename, the keywords style or stylesheet or css.
  2. Javascript templates optionally include, in their filename, the keywords js or javascript.

If we find one of these keywords in the filename but it does not match the template type given, we log a warning.

Template Examples

Simple Example

One reason this example is so simple is that it doesn't even require a separate template file, but instead uses StringToTemplateCache(). It also doesn't use sections or template-includes.


int main() {
  static const char template_text[] =
    "ERROR: {{FUNCTION}}({{ARGS}}) returned {{ERROR_CODE}}: {{ERROR_MESSAGE}}\n";
  ctemplate::StringToTemplateCache("mytpl", template_text, ctemplate::DO_NOT_STRIP);
  FILE* fp = fopen(argv[1], "r");
  if (fp == NULL) {
    int err_no = errno;   // squirrel this away
    ctemplate::TemplateDictionary dict("error_msg: fopen()");
    dict.SetValue("FUNCTION", "fopen");
    dict.SetValue("ARGS", argv[1]);
    dict.SetIntValue("ERROR_CODE", err_no);
    dict.SetValue("ERROR_MESSAGE", strerror(err_no));

    string error_text;
    ctemplate::ExpandTemplate("mytpl", ctemplate::DO_NOT_STRIP, &dict, &error_text);
    puts(error_text.c_str());
  }
}
Note: If this template was intended to run in a web application, you can leverage the functionality provided by the auto-escape mode. Simply add the AUTOESCAPE pragma directive at the top of the template text and your variables will be automatically escaped for the context you specify. For example, if your template is returned in an HTML context, change the template_text declaration as follows: 
  static const char template_text[] =
    "{{%AUTOESCAPE context=\"HTML\"}}"
    "ERROR: {{FUNCTION}}({{ARGS}}) returned {{ERROR_CODE}}: {{ERROR_MESSAGE}}\n";

This example is only slightly more complicated: we only print the ": <error message>" part when the error message isn't the empty string.


int main() {
  static const char template_text[] =
     "ERROR: {{FUNCTION}}({{ARGS}}) returned {{ERROR_CODE}}"
     "{{#MSG_SECTION}}: {{ERROR_MESSAGE}}{{/MSG_SECTION}}\n";
  ctemplate::StringToTemplateCache("mytpl", template_text, ctemplate::DO_NOT_STRIP);
  FILE* fp = fopen(argv[1], "r");
  if (fp == NULL) {
    int err_no = errno;   // squirrel this away
    ctemplate::TemplateDictionary dict("file_error_message");
    dict.SetValue("FUNCTION", "fopen");
    dict.SetValue("ARGS", argv[1]);
    dict.SetIntValue("ERROR_CODE", err_no);
    if (err_no > 0)
      dict.SetValueAndShowSection("ERROR_MESSAGE", strerror(err_no),
                                  "MSG_SECTION");

    string error_text;
    ctemplate::ExpandTemplate("mytpl", ctemplate::DO_NOT_STRIP, &dict, &error_text);
    puts(error_text.c_str());
  }
  delete tpl;
}

This maybe-show-text functionality is one way the template machinery is more powerful than just using printf. Another nice property of templates is you can reuse the same variable multiple times in your template string. You can also define the variable values in any order.

Search Results Page

Here is an example template that could be used to format a Google search results page:

Here is a sample procedure that could populate a dictionary for expanding that template. The "one procedure" entry point is fill_search_results_dictionary. The SetTemplateValues function is a separate entry point for initializing each top-level template with some standard values.

How To Use the Ctemplate (formerly Google Template) System

(as of )

Motivation

A template system can be used to separate output formatting specifications, which govern the appearance and location of output text and data elements, from the executable logic which prepares the data and makes decisions about what appears in the output.

Template systems lie along a continuum of power versus separation. "Powerful" constructs like variable assignment or conditional statements make it easy to modify the look of an application within the template system exclusively, without having to modify any of the underlying "application logic". They do so, however, at the cost of separation, turning the templates themselves into part of the application logic.

This template system leans strongly towards preserving the separation of logic and presentation. It is intentionally constrained in the features it supports and, as a result, applications tend to require quite a bit of code to instantiate a template. This may not be to everybody's tastes. However, while this design limits the power of the template language, it does not limit the power or flexibility of the template system. This system supports arbitrarily complex text formatting. Many Google applications, including the "main" Google web search, use this system for formatting output.

Finally, this system is designed with an eye towards efficiency. Template instantiation is very quick, with an eye towards minimizing both memory use and memory fragmentation.

Overview

There are two main parts to the Ctemplate System:

  • Templates
  • Data dictionaries

The templates are text files that contain the format specification for the formatted output, i.e, the template language. The data dictionaries contain the mappings from the template elements (markers) embedded in the templates to the data that they will format. Here's a simple template:

   <html><head><title>{{TITLE}}</title>{{META_TAGS}}</head>
   <body>{{BODY}}</body></html>

Here's a dictionary that one could use to instantiate the template:

   {"TITLE": "Template example",
    "BODY": "This is a simple template example.\nIt's boring",
    "DATE": "11/20/2005"}

If we instantiated the template with this dictionary (a process we call "expanding"), here's the output we would get:

   <html><head><title>Template example</title></head>
   <body>This is a simple template example.
It's boring</body></html>

{{TITLE}} and {{BODY}} are template elements, also called markers. In the dictionary, TITLE, BODY, and DATE are dictionary names, and the values associated with each one, such as 11/20/2005, are dictionary values.

A few points are clear even from this simple example:

  1. Dictionary keys and values are strings; the Ctemplate system is not typed.
  2. Dictionary values come already formatted. It was up to the application code to decide how to format the value for DATE, and to insert the date into the dictionary already formatted.
  3. Not all dictionary values must be used by a template. DATE is entirely ignored.
  4. Not all template elements may exist in the dictionary. In this example, {{META_TAGS}} is not found in the dictionary. This is perfectly legal; missing dictionary names evaluate to the empty string.

Templates

The template language has four major types of markers (the full list of marker types is described in the reference guide):

  1. Variable markers, which are replaced by text based on dictionary values. All markers in the above example are variable markers. Variable markers look like this: {{FOO}}
  2. Start section and end section markers, which delimit sections which may appear zero, one, or N times in the output. The number of times a section appears is determined by the data dictionaries, as explained below. Each time a section is expanded, it uses a different dictionary, so that the output values may be different from one iteration of a section expansion to another. Note that the specification of how sections expand is entirely dependent on the dictionary, as set up by the application; there is no way to specify a repeat count in the template language itself. Section markers look like this: {{#FOO}}...{{/FOO}}
  3. Template-include markers, which designate other templates to be expanded and inserted at the location where the marker appears. These are treated much like sections -- one may think of them as sections whose content is specified in a different file instead of inline -- and just like sections, can be expanded zero, one or N times in the output, each with a different dictionary and even a different include-file. Template-include markers look like this: {{>FOO}}
  4. Comment markers, which may annotate the template structure but drop completely out of the expanded output. Comment markers look like this: {{! comment lives here -- cool, no?}}

These marker types each have their own namespace. For readability, however, it is best to not overuse a single name.

Anything found in a template of the form {{...}} is interpreted as a template marker. All other text is considered formatting text and is output verbatim at template expansion time. Formatting text may consist of HTML tags, XML tags, linefeeds and other spacing characters, constant text, etc.

Data Dictionaries

A data dictionary is a map from keys to values. The keys are always strings, each string representing either a variable, a section, or a template-include file. (Comments are not stored in the data dictionary!) These values correspond to the name of the associated template marker: a section {{#FOO}} in the template text is matched to the key "FOO" in the dictionary, if it exists. Note the case must match as well.

The value associated with a key differs according to key type. The value associated with a variable is simple: it's the value for that variable. Both keys and values can be any 8-bit character-string, and may include internal NULs (\0).

The value associated with a section is more complicated, and somewhat recursive: it's a list of data dictionaries. Come template-expansion time, the section is expanded once for each dictionary in the list, so if there are two dictionaries in the list, then the section text will occur in the output twice. The first time, all variables/etc. in the section will be evaluated taking into account the first dictionary. The second time, all variables/etc. will be evaluated taking into account the second dictionary. (See below for a definition of "taking into account.")

A template-include is a special type of section, so the associated value is the same: a list of dictionaries. Template-includes also have one other, mandatory associated piece of information: the filename of the template to include.

The application program is responsible for building this data dictionary, including all nesting. It then applies this dictionary to a single template to produce formatted output.

Expanding a Template

A program using Ctemplate typically reads in templates at load time. During the course of program execution, the program will repeatedly perform the following two steps: first, instantiate a data dictionary, and second, apply the dictionary to the template to produce output.

The template system applies a dictionary to a template by finding all template markers in the template, and replacing them with the appropriate dictionary values. It matches template markers to dictionary keys in the obvious way. For instance, a template marker {{FOO}} matches the dictionary key FOO. The marker {{#BAR}} matches the dictionary key BAR, as does the marker {{/BAR}}. The marker {{>BAZ}} matches the dictionary key BAZ. (And of course, the marker {{! comment}} doesn't match any dictionary key at all.)

If no dictionary key is found for a given template marker, then the template marker is ignored: if a variable, it expands to the empty string; if a section or include-template, the section or include-template is expanded zero times.

All names are case sensitive. Names -- that is, variable keys and, as a result, template markers -- must be made of (7-bit ascii) alphanumeric characters and the underscore. The comment marker, which does not map to dictionary keys, may contain any characters whatsoever except }, the close-curly brace. It's a syntax error for any template marker to violate this rule.

Outside of the template markers, templates may contain any text whatsoever, including (single) curly braces and NUL characters.

Auto Escape Mode

The Auto Escape mode helps protect against cross-site scripting (XSS) attacks in web-applications by automatically escaping variables in your template. The Guide to using Auto Escape has an overview of Auto Escape as well as discussion of its limitations.

Auto Escape is enabled on a template-by-template basis. Simply add the AUTOESCAPE pragma to the desired template. That template will then be automatically escaped, independently of the templates it may include or it may be included from. The AUTOESCAPE pragma must be placed at the top of the template. It takes a 'context' argument saying what context the template is used in: html, javascript, css, xml, etc. (There's also a state=IN_TAG argument that is used when the template is just a snippet of html intended for use in a tag.) See the reference guide for a full description of autoescape arguments.

The table below shows four small sample templates along with their corresponding AUTOESCAPE pragma. The two most common contexts are HTML and JAVASCRIPT. We also show a sample template for the CSS context as well as a sample template for the IN_TAG state of HTML (although it is expected to be rarely used).

HTML JAVASCRIPT CSS HTML IN_TAG (uncommon) 
    {{%AUTOESCAPE context="HTML"}}

    <body>
      <p>Hello {{USER}}</p>
      <p><a href="{{URL}}">Your Account</a></p>
    </body>
    
    {{%AUTOESCAPE context="JAVASCRIPT"}}

    function showMessage(user, msg) {
      alert("Hello: " + user + " Message: " + msg);
    }

    var user = '{{USER}}';
    var msg = '{{MSG}}';
    showMessage(user, msg);
    
    {{%AUTOESCAPE context="CSS"}}

    P.abstract {
      text-align:{{EDGE}};
      font-size:{{FONT_SIZE_PC}};
    }
    .italic {font-style:{{ITALIC}}}
    
    {{%AUTOESCAPE context="HTML" state="IN_TAG"}}

    class="{{CLASS}}" id="{{ID}}"

Auto-escaping works by automatically applying modifiers to every variable in the template. You can manually apply modifiers as well, and even define your own. See the reference guide for a full discussion of modifiers and how to use them.

Details on Dictionary Lookup

The dictionary structure is a tree: there's a 'main' dictionary, and then a list of sub-dictionaries for each section or include-template. Even with all this complexity, the lookup rules are mostly straightforward: when looking up a marker -- be it a variable, section, or include-template marker -- the system looks in the currently applicable dictionary. If it's found there, great. If not, and the parent dictionary is not an include-template, it continues the look in the parent dictionary, and possibly the grandparent, etc. That is, lookup has static scoping: you look in your dictionary and any parent dictionary that is associated with the same template-file. As soon as continuing the lookup would require you to jump to a new template-file (which is what include-template would do), we stop the lookup.

For instance, for a template that says {{#RESULTS}}{{RESULTNUM}}. {{>ONE_RESULT}}{{/RESULTS}}, "ONE_RESULT" is looked for in the "RESULTS" dictionary, and if not found there, is looked for in the main, top-level dictionary. Likewise, the variable "RESULTNUM" is looked for first in the "RESULTS" dictionary, then in the main dictionary if necessary. However, "ONE_RESULT" will not do equivalent cascading lookups. In fact, it will have no parent dictionaries at all, because it's a different template file and thus in a different scope.

Because of these scoping rules, it's perfectly reasonable to set all variables that are needed in a given template file, in the top-level dictionary for that template. In fact, the ShowSection() function is provided to support just this idiom. To avoid confusion in such a usage mode, it's strongly encouraged that you give unique names to all sections and include-templates in a single template file. (It's no problem, given the template scoping rules, for a single section or include-template name to be repeated across different template files.)

There's a single special case: the global variable dictionary. Every dictionary inherits its initial set of values from the global dictionary. Clients can set variables in the global dictionary just like they can in normal template dictionaries they create.

The system initializes the global dictionary with a few useful values for your convenience. All system variables are prefixed with BI, to emphasize they are "built in" variables.

  • BI_SPACE, which has the value <space>. It is used to force a space at the beginning or end of a line in the template, where it would normally be suppressed. (See below.)
  • BI_NEWLINE, which has the value <newline> It is used to force a newline at the end of a line, where it would normally be suppressed. (See below.)

As is usual for inheritance, if a user explicitly assigns a value to these variable-names in its own dictionary, this overrides the inherited value. So, dict->SetValue("BI_SPACE", "&nbsp;") causes BI_SPACE to have the value &nbsp;, rather than <space>, when expanding dict.

Note that only variables can be inherited from the global dictionary, not section dictionaries or include-file dictionaries.

A couple of small implementation notes: global inheritance is "last chance", so if a section's parent dictionary redefined BI_SPACE, say, the section dictionary inherits the parent-dict value, not the global-dict value. Second, variable inheritance happens at expand time, not at dictionary-create time. So if you create a section dictionary, and then afterwards set a variable in its parent dictionary (or in the global dictionary), the section will inherit that variable value, if it doesn't define the value itself.

Writing Application Code To Use Templates

Most application code concerns filling a template dictionary, but there is also code for expanding templates given a dictionary. A final category of code lets you inspect and control the template system.

Creating A Template Dictionary

The class TemplateDictionary is used for all template dictionary operations. new ctemplate::TemplateDictionary(name) is used to create a new top-level dictionary. dict->AddSectionDictionary(name) and dict->AddIncludeDictionary(name) are used to create sub-dictionaries for sections or include-files. After creating a dictionary, the application should call one or more functions for each marker in the template. As an example, consider the following template: 

<html><body> {{! This page has no head section.}}
{{#CHANGE_USER}}
<A HREF="/login">Click here</A> if you are not {{USERNAME}}<br>
{{/CHANGE_USER}}

Last five searches:<ol>
{{#PREV_SEARCHES}
<li> {{PREV_SEARCH}}
{{/PREV_SEARCHES}}
</ol>

{{>RESULT_TEMPLATE}}

{{FOOTER}}
</body></html>

To instantiate the template, the user should call a function to set up FOOTER, and a function to say what to do for the sections CHANGE_USER and PREV_SEARCHES, and for the include-template RESULT_TEMPLATE. Quite likely, the application will also want to create a sub-dictionary for CHANGE_USER, and in that sub-dictionary call a function to set up USERNAME. There will also be sub-dictionaries for PREV_SEARCHES, each of which will need to set PREV_SEARCH. Only when this is all set up will the application be able to apply the dictionary to the template to get output.

The appropriate function to call for a given template marker depends on its type.

Variables

For variables, the only interesting action is to set the variable's value. For most variables, the right method to call is dict->SetValue(name, value). (The name and value can be specified as strings in a variety of ways: C++ strings, char *'s, or char *'s plus length.)

There are two other ways to set a variable's value as well, each with a different scoping rule. You can call ctemplate::TemplateDictionary::SetGlobalValue(name, value) -- no TemplateDictionary instance needed here -- to set a variable that can be used by all templates in an application. This is quite rare.

You can also call dict->SetTemplateGlobalValue(name, value). This sets a variable that is seen by all child dictionaries of this dictionary: sub-sections you create via AddSectionDictionary, and included templates you create via AddIncludeDictionary (both described below). This differs from SetValue(), because SetValue() values are never inherited across template-includes. Almost always, SetValue is what you want; SetTemplateGlobalValue is intended for variables that are "global" to a particular template tree not all template trees, such as a color scheme to use, a language code, etc.

To make it easier to use SetValue(), there are a few helper routines to help setting values of a few special forms.

  • SetIntValue(name, int): takes an int as the value.
  • SetFormattedValue(name, fmt, ...): the fmt and ... work just like in printf: SetFormattedValue("HOMEPAGE", "http://%s/", hostname).

Example:

   ctemplate::TemplateDictionary* dict = new ctemplate::TemplateDictionary("var example");
   dict->SetValue("FOOTER", "Aren't these great results?");

Sections

Sections are used in two ways in templates. One is to expand some text multiple times. This is how PREV_SEARCHES is used in the example above. In this case we'll have one small sub-dictionary for each of the five previous searches the user did. To do this, call AddSectionDictionary(section_name) to create the sub-dictionary. It returns a TemplateDictionary* that you can use to fill the sub-dictionary.

The other use of sections is to conditionally show or hide a block of text at template-expand time. This is how CHANGE_USER is used in the example template: if the user is logged in, we show the section with the user's username, otherwise we choose not to show the section.

This second case is a special case of the first, and the "standard" way to show a section is to expand it exactly one time, by calling AddSectionDictionary() once, and then setting USERNAME in the sub-dictionary.

However, the hide/show idiom is so common there are a few convenience methods to make it simpler. The first takes advantage of the fact sections inherit variables from their parent: you set USERNAME in the parent dictionary, rather than a section sub-dictionary, and then call ShowSection(), which adds a single, empty dictionary for that section. This causes the section to be shown once, and to inherit all its variable values from its parent.

A second convenience method is written for the particular case we have with USERNAME: if the user's username is non-empty, we wish to show the section with USERNAME set to the username, otherwise we wish to hide the section and show neither USERNAME nor the text around it. The method SetValueAndShowSection(name, value, section_name) does exactly that: if value is non-empty, add a single dictionary to section_name and call section_dict->AddValue(name, value).

Example:

   ctemplate::TemplateDictionary* dict = new ctemplate::TemplateDictionary("section example");
   const char* username = GetUsername();   // returns "" for no user
   if (username[0] != '\0') {
      ctemplate::TemplateDictionary* sub_dict = dict->AddSectionDictionary("CHANGE_USER");
      sub_dict->SetValue("USERNAME", username);
   } else {
      // don't need to do anything; we want a hidden section, which is the default
   }

   // Instead of the above 'if' statement, we could have done this:
   if (username[0] != '\0') {
      dict->ShowSection("CHANGE_USER");       // adds a single, empty dictionary
      dict->SetValue("USERNAME", username);   // take advantage of inheritance
   } else {
      // don't need to do anything; we want a hidden section, which is the default
   }

   // Or we could have done this:
   dict->SetValueAndShowSection("USERNAME", username, "CHANGE_USER");

   // Moving on...
   GetPrevSearches(prev_searches, &num_prev_searches);
   if (num_prev_searches > 0) {
      for (int i = 0; i < num_prev_searches; ++i) {
         TemplateDictionary* sub_dict = dict->AddSectionDictionary("PREV_SEARCHES");
         sub_dict->SetValue("PREV_SEARCH", prev_searches[i]);
      }
   }

Template-includes

Template-include markers are much like section markers, so AddIncludeDictionary(name) acts, not surprisingly, exactly like AddSectionDictionary(name). However, since variable inheritance doesn't work across include boundaries, there is no template-include equivalent to ShowSection() or SetValueAndShowSection().

One difference between template-includes and sections is that for a sub-dictionary that you create via AddIncludeDictionary(), you must call subdict->SetFilename() to indicate the name of the template to include. If you do not set this, the sub-dictionary will be ignored. The filename may be absolute, or relative, in which case it's relative to some entry in the template search path.

Example:

   using ctemplate::TemplateDictionary;
   TemplateDictionary* dict = new TemplateDictionary("include example");
   GetResults(results, &num_results);
   for (int i = 0; i < num_results; ++i) {
      TemplateDictionary* sub_dict = dict->AddIncludeDictionary("RESULT_TEMPLATE");
      sub_dict->SetFilename("results.tpl");
      FillResultsTemplate(sub_dict, results[i]);
   }

In practice, it's much more likely that FillResultsTemplate() will be the one to call SetFilename(). Note that it's not an error to call SetFilename() on a dictionary even if the dictionary is not being used for a template-include; in that case, the function is a no-op, but is perhaps still useful as self-documenting code.

Another property of template-includes is that they set the indentation level for the included template, that is, every line in the included template is indented by the same amount as the template-includes line itself. For instance, if you have a template PRINT_STUFF like this:

print "Hello!"
print "You are the 10th caller!"
print "Congratulations!"

and you include it in the template:

   if ShouldPrintStuff():
     {{>PRINT_STUFF}}
   else:
     pass

then when it is expanded, all three print lines will be indented, not just the first one:

   if ShouldPrintStuff():
     print "Hello!"
     print "You are the 10th caller!"
     print "Congratulations!"
   else:
     pass

Note that this behavior is immaterial when using STRIP_WHITESPACE, since in that case all leading whitespace is stripped.

Expanding a Template

Once you have a template dictionary, it's simplicity itself to expand the template with those dictionary values, putting the output in a string:

   ctemplate::TemplateDictionary dict("debug-name");
   FillDictionary(&dict, ...);
   string output;
   bool error_free = ctemplate::ExpandTemplate(<filename>, ctemplate::STRIP_WHITESPACE, &dict, &output);
   // output now holds the expanded template.
   // ExpandTemplate returns false if the system cannot load-and-parse
   // <filename> or any of the template files referenced by the
   // TemplateDictionary.

The first argument to ExpandTemplate is the filename holding the template to expand (though there are ways to use non-file-based templates as well). The second argument is the "strip" mode, which specifies how to treat whitespace in the template. It can take the following values:

  • ctemplate::DO_NOT_STRIP: do nothing. This expands the template file verbatim.
  • ctemplate::STRIP_BLANK_LINES: remove all blank lines. This ignores any blank lines found in the template file when parsing it. When the template is html, this reduces the size of the output text without requiring a sacrifice of readability for the input file.
  • ctemplate::STRIP_WHITESPACE: remove not only blank lines when parsing, but also whitespace at the beginning and end of each line. It also removes any linefeed (possibly following whitespace) that follows a closing }} of any kind of template marker except a template variable. (This means a linefeed may be removed anywhere by simply placing a comment marker as the last element on the line.) When the template is html, this reduces the size of the output html without changing the way it renders (except in a few special cases.) When using this flag, the built-in template variables BI_NEWLINE and BI_SPACE can be useful to force a space or newline in a particular situation.

The expanded template is written to the string output. If output was not empty before calling Expand(), the expanded template is appended to the end of output.

There is also a "power user" version of ExpandTemplate(), called ExpandWithData(), that allows you to pass in per-expand data. Another "power user" version allows you to expand the template into a custom output container, rather than a string. See the reference guide for more information about these advanced methods.

Getting a Template From a String Rather Than a File

The first argument to ExpandTemplate is named "filename", suggesting that the template has to be read from an on-disk file. But in reality, the "filename" argument is just a key into an internal cache. (By default, the template system looks on disk to satisfy a cache miss, hence the "filename" to describe this variable.) If you have a template specified in a string rather than a file, you can manually insert it into the cache via ctemplate::StringToTemplateCache().

StringToTemplateCache() parses the string you pass in as if it were a template file, and inserts it into the global cache with the key and strip-mode that you provide. You can then use this key and strip-mode as the first two arguments to ExpandTemplate. You can also use the key as the argument to ctemplate::TemplateDictionary::SetFilename().

Prefer file-based to string-based templates where possible. Updating a file-based template requires merely a data push, rather than pushing the new executable, and it also makes it easier for non-programmers to modify the template. One reason to use string-based templates is if you are in an environment where having data files could be dangerous—for instance, you work on a disk that is usually full, or need the template to work even in the face of disk I/O errors.

This package comes with a script, template-converter, that takes a template file as input and emits a C++ code snippet (an .h file) that defines a string with those template contents. This makes it easy to start by using a normal, file-based template, and then switch to StringToTemplateCache() later if you so desire.

Copying a Template Dictionary

You can use the MakeCopy() method on a template dictionary to make a "deep" copy of the template. This can be useful for situations like the following: you want to fill a template several times, each time with 90% of the values the same, but the last 10% different. Computing the values is slow. Here's how you can use MakeCopy() to do it:

  1. fill dict with 90%
  2. newdict1 = dict->MakeCopy();
  3. fill newdict1 with last 10%
  4. newdict2 = dict->MakeCopy();
  5. fill newdict2 with last 10%
  6. etc.

The Template Cache

When templates are loaded from disk, they are stored in an internal template cache, which is used by ExpandTemplate() and (most obviously) StringToTemplateCache(). You can define your own template cache with the TemplateCache class.

This is an advanced technique used when you want to support having several versions of a template file in memory at the same time (for instance, a webserver might want to keep an old version of a template file around until all old requests using that template are done being serviced). It also supports advanced operations like removing a template from the cache, and reloading templates from disk if they have changed.

See the reference manual for more details about the template cache.

Template and Threads

All expansion functions and static TemplateDictionary methods are threadsafe: you can safely call ctemplate::TemplateDictionary::SetGlobalValue() without needing to worry about locking.

Non-static TemplateDictionary methods are not thread-safe. It is not safe for two threads to assign values to the same template-dictionary without doing their own locking. Note that this is expected to be quite rare: usually only one thread will care about a given template-dictionary.

Testing Templates

Templates have the advantage that they separate the presentation of your data from the application logic that generates the data. Naturally, you want to do the same for testing: you would like to test the application's logic in a way that is robust to changes in the presentation.

The easiest way to test this logic is with unit tests that exercise the functions in your code that fill template dictionaries. The class ctemplate::TemplateDictionaryPeer in template_test_util.h is designed to help you do exactly that.

Here's a sample test using TemplateDictionaryPeer:

   void MyTestMethod() {
     // Create and populate the dictionary as your app normally would.
     // In this case, we create a dict with data like this:
     // { color:blue,
     //   shape_section: [
     //     { size:big, num_sides:7 },
     //     { size:big, num_sides:7 },
     //     { size:big, num_sides:7 }
     //   ]
     // }
     MyObject obj;
     ctemplate::TemplateDictionary dict;
     obj.FillDictionary(&dict);
     // Create a TemplateDictionaryPeer to gain access to the dict contents.
     ctemplate::TemplateDictionaryPeer peer(&dict);
     // Expect color:blue at the top level of this dictionary.
     EXPECT_STREQ("blue", peer.GetSectionValue("color"));
     // Fetch sub-dictionaries from the dict.
     vector<const ctemplate::TemplateDictionary*> shape_dicts;
     peer.GetSectionDictionaries("shape_section", &shape_dicts);
     EXPECT_EQ(3, shape_dicts.size());
     for (int i = 0; i < 3; ++i) {
       // Create another peer for each sub-dict, and assert that each sub-dict
       // contains the expected data.
       ctemplate::TemplateDictionaryPeer shape_peer(dicts[i]);
       EXPECT_STREQ("big", shape_peer.GetSectionValue("size"));
       EXPECT_STREQ("7", shape_peer.GetSectionValue("num_sides"));
     }
   }

Note that by using TemplateDictionaryPeer, you can unit test the code for filling a TemplateDictionary independent of the consuming Template.

The above tests your dictionary filling functions, but doesn't touch the template expansion. Naturally, you may also want to test the template itself. In this case, you will want to avoid using your program's dictionary filling functions, and will instead provide a custom dictionary in your test. There are a variety of properties you might want to test about the template, but here are a few sample tests:

   void TestTemplateHTMLEscapesColor() {
     // Populate a dictionary that lets us exercise the condition we're testing.
     // In this case, that the 'color' tag will be HTML escaped.
     ctemplate::TemplateDictionary dict("t1");
     dict.SetValue("color", "<blue>");
     // Expand the template with this dictionary.
     string result;
     ctemplate::ExpandTemplate(FLAGS_test_srcdir + "templates/my_template.html",
                               ctemplate::STRIP_WHITESPACE, &dict, &result);
     // Assert that the expansion has the appropriate text in it.
     EXPECT_THAT(result, HasSubstr("&lt;blue&gt;"));
   }

   void TestColorAppearsBeforeShape() {
     // This time, the condition under test is that the "color" element of
     // the dictionary appears before the "shape" element.
     // Create an appropriate dictionary.
     ctemplate::TemplateDictionary dict("t2"); // Note: use sufficiently unique
     dict.SetValue("color", "white_asdf");     // strings that they won't occur
     dict.SetValue("shape", "square_asdf");    // "bare" in the template.

     string result;
     ctemplate::ExpandTemplate(FLAGS_test_srcdir + "templates/my_template.html",
                               ctemplate::STRIP_WHITESPACE, &dict, &result);
     // Assert that color comes before shape.
     EXPECT_THAT(result, ContainsRegex("white_asdf.*square_asdf"));
   }

Security Considerations

Like all web applications, programs that use the Ctemplate System to create HTML documents can be vulnerable to Cross-Site-Scripting (XSS) attacks unless data inserted into a template is appropriately sanitized and/or escaped. Which specific form of escaping or sanitization is required depends on the context in which the template variable appears within a HTML document (such as, regular "inner text", within a <script> tag, or within an onClick handler).

If you are concerned with XSS, your are strongly encouraged to leverage the Auto Escape mode developed specifically to better defend your application against XSS. The Auto Escape mode follows the guidelines outlined below. Do note however that regardless of whether you use Auto Escape or not, escaping alone while generally required, is often not enough! You also may need to sanitize or validate the input, as for instance with URL attributes. For further information, refer to additional resources on Cross-Site-Scripting issues.

The remainder of this section provides a brief summary of techniques to prevent XSS vulnerabilities due to template variables in various HTML contexts.
  1. Regular text (outside of tags and other special situations).

    Use the auto-escape pragma to html-escape the variable.

  2. HTML tag attributes.

    In addition to the auto-escape pragma, ensure that the attribute is enclosed in double quotes in the template.

  3. URL attributes (eg., href/src).

    In addition to the auto-escape pragma, ensure that the attribute is enclosed in double quotes in the template.

  4. Beware of inserting variables containing data from untrusted sources into the context of a style tag or attribute.

    Certain CSS style-sheet constructs can result in the invocation of javascript. To prevent XSS, the variable must be carefully validated and sanitized.

  5. Populating javascript variables.

    In addition to the auto-escape pragma, ensure that the literal is enclosed in quotes in the template:

         <script>
       var msg_text  = '{{MESSAGE}}';
     </script>

    Literals of non-string types cannot be quoted and escaped. Instead, ensure that the variable's value is set such that it is guaranteed that the resulting string corresponds to a javascript literal of the expected type. For example, use

           dict->SetValueInt("NUM_ITEMS", num_items);

    to populate an integer javascript variable in the template fragment

         <script>
       var num_items = {{NUM_ITEMS}};
     </script>
  6. Populating javascript variables within event handlers such as onClick.

    Tag attributes whose values are evaluated as a javascript expression (such as on{Click,Load,etc} handlers) generally require HTML-Escape in addition to Javascript-Escape, since the attribute's value is HTML-unescaped by the browser before it is passed to the javascript interpreter.

    However, the javascript-escaping provided by auto-escape makes a subsequent HTML-Escape unnecessary. As such you can apply the same rules for variables within event handlers as you would for javascript variables in string literals:

           <button ...
                    onclick='GotoUrl("{{TARGET_URL}}");'>
  7. Consider potential non-template sources of XSS.

    There are a number of scenarios in which XSS can arise that are unrelated to the insertion of values into HTML templates, including,

    • injection into HTTP headers such as Location,
    • incorrect browser-side guess of the content-encoding of a HTML document without explicitly specified charset,
    • incorrect browser-side guess of a non-HTML document's content-type that overrides the document's specified Content-Type,
    • browser-side handling of documents served for download-to-disk (Content-Disposition: attachment).

    Please consult additional documentation on Cross-Site-Scripting for more detailed discussion of such issues.

Working Effectively with Templates

Registering Template Strings

Both dictionary keys and template filenames are strings. Instead of using raw strings, we encourage you to use a bit of machinery to help protect against various types of errors.

For dictionary keys, you can use the make_tpl_varnames_h tool to create static string variables to use instead of a string constant. This will protect against typos, as the make_tpl_varnames_h documentation describes. It also yields slightly more efficient code.

For template filenames that a program uses -- including sub-templates -- we suggest the following idiom:

   #include "example.tpl.varnames.h"   // defines 1 string per dictionary key
   RegisterTemplateFilename(EXAMPLE_FN, "example.tpl");   // defines template
   ...
   include_dict->SetFilename(EXAMPLE_FN);
   ...
   ctemplate::ExpandTemplate(EXAMPLE_FN, ctemplate::DO_NOT_STRIP, ...);
   ...

By registering the filename, you can query the template system to detect syntax errors, reload-status, and so forth.

Managing Templates

There are methods to change the global state of the template system, to examine templates, and to examine template dictionaries. See the reference guide for more information.

Ctemplate System

Status: Current   (as of 25 April 2008)

Welcome to the C++ CTemplate system! (This project was originally called Google Templates, due to its origin as the template system used for Google search result pages, but now has a more general name matching its community-owned nature.)

As a quick start, here's a small but complete program that uses this template library. For more details see, the links below.

Template file example.tpl

   Hello {{NAME}},
   You have just won ${{VALUE}}!
   {{#IN_CA}}Well, ${{TAXED_VALUE}}, after taxes.{{/IN_CA}}

C++ program example.cc

   #include <stdlib.h>
   #include <string>
   #include <iostream>
   #include <ctemplate/template.h>
   int main(int argc, char** argv) {
      ctemplate::TemplateDictionary dict("example");
      dict.SetValue("NAME", "John Smith");
      int winnings = rand() % 100000;
      dict.SetIntValue("VALUE", winnings);
      dict.SetFormattedValue("TAXED_VALUE", "%.2f", winnings * 0.83);
      // For now, assume everyone lives in CA.
      // (Try running the program with a 0 here instead!)
      if (1) {
        dict.ShowSection("IN_CA");
      }
      std::string output;
      ctemplate::ExpandTemplate("example.tpl", ctemplate::DO_NOT_STRIP, &dict, &output);
      std::cout << output;
      return 0;
   }

Compiling and linking (using gcc)

   gcc -o example example.cc -lctemplate_nothreads

I can use the "nothreads" library because example.cc doesn't use threads. If example.cc were threaded, I would do something like this instead:

   gcc -o example example.cc -lctemplate -pthread

See the README for more details about the two different ctemplate libraries.

Overview

The main class used by the template system is TemplateDictionary, which is used to expand a template file. It is used by the main functions for expanding a template, found in template.h.

TemplateCache is used to hold a collection of Template objects. TemplateNamelist provides various introspection routines on collections of Template objects.

TemplateModifier and PerExpandData are used to modify the values of a TemplateDictionary at expand time. TemplateAnnotator does too, but is intended for debugging purposes. TemplateDictionaryPeer is used for testing template code.

ExpandEmitter provides the ability to emit an expanded template to an arbitrary output store.

TemplateString is a string-like class that is built to be very efficient when used with the template system. For instance, tools are available to hash constant TemplateString objects at compile-time, speeding up their use at run-time.

The rest of this document describes these classes and functions in more detail, as well as build tools and other mechanisms for handling templates.

(Note: the code snippets below all assume the default configuration option is set, which puts template code in namespace ctemplate.)

Expanding Templates

The Template Language

Templates are strings that contain special formatting code called template markers. In the Ctemplate System, template strings are usually read from a file.

Anything found in a template of the form {{...}} is interpreted as a template marker. All other text is considered formatting text and is output verbatim at template expansion time. Outside of the template markers, templates may contain any text whatsoever, including (single) curly braces and NUL characters.

The template language has six types of markers:

  1. Variable markers, which are replaced by text based on dictionary values. Variable markers look like this: {{FOO}}
  2. Start section and end section markers, which delimit sections which may appear zero, one, or N times in the output. Section markers look like this: {{#FOO}}...{{/FOO}}
  3. Template-include markers, which designate other templates to be expanded and inserted at the location where the marker appears. These are treated much like sections -- one may think of them as sections whose content is specified in a different file instead of inline -- and just like sections, can be expanded zero, one or N times in the output, each with a different dictionary. Template-include markers look like this: {{>FOO}}
  4. Comment markers, which may annotate the template structure but drop completely out of the expanded output. Comment markers look like this: {{! comment lives here -- cool, no?}}
  5. Set-delimiter markers, which change the marker delimiters from {{ and }} to custom strings. (The only requirement is that these strings not contain whitespace or the equals sign.) This is useful for languages like TeX, where double-braces may occur in the text and are awkward to use for markup. Set-delimiter markers look like this: {{=< >=}} <! Now markers are delimited by braces > <=| |=> |! And now markers are delimited by bars! |
  6. Pragma markers, which invoke additional built-in template features when processing the template. Pragma markers look like this: {{%PRAGMA [name="value"...]}}. Currently, AUTOESCAPE is the only pragma defined.

These marker types each have their own namespace. For readability, however, it is best to not overuse a single name.

Modifiers

A variable and include-template can have one or more modifiers attached to them, like so:

   {{MYVAR:mod1:mod2:mod3=value:mod4=value with spaces:mod5}}

A modifier is a filter that's applied at template-expand time, that munges the value of the variable before it's output. See the TemplateModifier class for more details.

When expanding a variable (or template-include) with a modifier, the modifiers are applied in order, left to right. For a template-include, first the entire sub-template is expanded, as a single string, and then the modifiers are applied to that string.

In general, using explicit modifiers does not turn off auto-escaping on a variable. The explicit modifier :none does suppress auto-escaping.

Special Markers

Some marker names may have a special meaning in the template system. Right now, there's one such name.

Separator Sections

If you have a section named FOO, you can define inside of it a section named FOO_separator, and the template system will automatically expand that section every time FOO is expanded, except for the last. Thus, the contents of FOO_separator can be used to separate repeated values of a section.

Here's an example:

   Here are the meeting attendees:
   {{#ATTENDEES}}
      {{NAME}}
      {{#ATTENDEES_separator}}, {{/ATTENDEES_separator}}
   {{/ATTENDEES}}
   .

Here is a more convoluted example, to show the date:

   {{#DATE}}{{DATE_COMPONENT}}{{#DATE_separator}}{{DATE_SEP}}{{/DATE_separator}}{{/DATE}}

You'd set up a template dictionary to repeat DATE three times, with DATE_COMPONENT set to the month, day, and year (or day, month, and year, depending on your locale...), and DATE_SEP set to / or - or whatever date-separator is called for.

SEP_separator is always evaluated with the current dictionary. Thus, in the date example, if you wanted a different separator each time, you could do so by setting DATE_SEP to a different value for each repetition of DATE.

While SEP_separator is automatically expanded by the template system, it is otherwise a perfectly normal section. You can even instantiate it yourself by calling AddSectionDictionary("SEP_separator"). In that case, the section will be expanded both via the automatic expansion as a separator, and as a normal section via the section dictionary you added. This is more confusing than helpful, and you should probably never do it.

There can be at most one "separator" sub-section per section. If there are more, only the last is automatically expanded.

Specifying a template

In the template system -- in functions like ExpandTemplate() -- a template is specified by a pair: filename + strip-mode. The filename specifies the name of the template file on disk (but see below for string templates). The strip mode specifies how this file should be parsed as it's read from disk, in particular, how whitespace should be handled. It can take the following values:

  • ctemplate::DO_NOT_STRIP: do nothing. This expands the template file verbatim.
  • ctemplate::STRIP_BLANK_LINES: remove all blank lines. This ignores any blank lines found in the template file when parsing it. When the template is html, this reduces the size of the output text without requiring a sacrifice of readability for the input file.
  • ctemplate::STRIP_WHITESPACE: remove not only blank lines when parsing, but also whitespace at the beginning and end of each line. It also removes any linefeed (possibly following whitespace) that follows a closing }} of any kind of template marker except a template variable. (This means a linefeed may be removed anywhere by simply placing a comment marker as the last element on the line.) When the template is html, this reduces the size of the output html without changing the way it renders (except in a few special cases.) When using this flag, the built-in template variables BI_NEWLINE and BI_SPACE can be useful to force a space or newline in a particular situation.

The filename is where the template file lives on disk. It can be either an absolute filename, or relative to a directory in the template search path.

In addition to reading a template from disk, it is possible to read a template from a string, using StringToTemplateCache(). The first argument of StringToTemplateCache() is a "key" to use to refer to this string-based template. This key takes the place of the filename, for any routine that asks for a filename + strip.

ExpandTemplate()

This is the main workhorse function of the template system. It takes the filename of a template, a template dictionary, and a string to emit to, and emits an "expanded" version of the template using the given template dictionary to fill in the template markers.

If the template specified by the given filename is already found in an internal cache, the cached version of the template is used, otherwise the template is loaded from disk, parsed, and stored in the cache before expansion is performed. As always, the "filename" can also be a key to a string-based template, inserted directly into the cache via StringToTemplateCache().

There is an overloaded version of Expand() that takes an ExpandEmitter rather than a string, as the source to expand the template into.

This function returns true if the template was successfully expanded into the output parameter. It returns false if expansion failed or was only partially successful. It might fail because the template file cannot be found on disk, or because the template has syntax errors and cannot be parsed, or because the template sub-includes another template, and that sub-template has errors. To minimize the risk of errors at expand-time, you can call LoadTemplate() (below) first to load and parse the template into the cache. This will catch all errors except for errors involving sub-templates.

In the case of partial failures -- typically, failures resulting in an error in a sub-inclued template -- there may be partial data emitted to the output before the error was detected. If ExpandTemplate() returns false, you should be careful to check for and remove this partial data, if desired.

ExpandWithData()

ExpandWithData() is like ExpandTemplate(), with the addition that it allows you to pass in per-expand data. It's called like this:

   ctemplate::TemplateDictionary dict(...);
   ctemplate::PerExpandData per_expand_data;
   string output;
   ctemplate::ExpandWithData(filename, strip_mode, &output, &dict,
                             &per_expand_data);

Per-expand data is applied to all templates that are seen while expanding: not only the template you called Expand() on, but also sub-templates that are brought in via template-includes ({{>INCLUDE}}). See the description of the PerExpandData class for more details about how expansion can be modified by per-expand data.

The return value has the same meaning as for ExpandTemplate() In fact, if you pass in NULL as the per_expand_data argument, this function is exactly equivalent to ExpandTemplate().

LoadTemplate()

This function takes a filename and a strip-mode, and loads the file into the default template cache. Future calls to ExpandTemplate() or ExpandWithData() will get the parsed template from the cache, without needing to go to disk.

This function returns true if the template was successfully read from disk, parsed, and inserted into the cache. It will also return true if the template is already in the cache (even if the file has changed on disk since the template was inserted into the cache). It will return false if the file cannot be found on disk, or cannot be successfully parsed. (Note that LoadTemplate() cannot detect errors in sub-included templates, since the identity of sub-included templates is specified in a TemplateDictionary, not in the template itself.)

StringToTemplateCache()

In addition to reading a template file from disk, it is also possible to read a template file from a string, using StringToTemplateCache(). It takes the content as a string. It also takes in a key and a strip mode. The given key and strip mode can be used as the filename/strip pair in calls to ExpandTemplate() and similar functions. The key can also be used as the "filename" in calls to ctemplate::TemplateDictionary::SetFilename(), allowing this template to be included inside other templates.

StringToTemplateCache() returns true if the string is successfully inserted into the cache. It returns false otherwise, probably because there is already a string or filename in the cache with the same key.

default_template_cache() and mutable_default_template_cache()

All the above routines -- ExpandTemplate(), LoadTemplate(), and the like -- read and write parsed templates to the default template cache. This is just a static instance of the TemplateCache class. It can be accessed via these two functions: default_template_cache() and, if you need a non-const version of the cache, mutable_default_template_cache(). These can be useful if you need the advanced features of template caches, such as ReloadAllIfChanged() or ClearCache().

The TemplateDictionary Class

The class TemplateDictionary is used for all template dictionary operations. In general, an application will need to call a TemplateDictionary method for every marker in the associated template (the major exception: markers that evaluate to the empty string can be ignored).

The appropriate function to call for a given template marker depends on its type.

Data Dictionaries

A data dictionary is a map from keys to values. The keys are always strings, corresponding to the name of the associated template marker, so a section {{#FOO}} in the template text is matched to the key FOO in the dictionary, if it exists. Note the case must match as well.

The value associated with a key differs according to key type. The value associated with a variable is simple: it's the value for that variable. Both keys and values can be any 8-bit character-string, and may include internal NULs (\0).

The value associated with a section is a list of data dictionaries. At template-expansion time, the section is expanded once for each dictionary in the list. The first time, all variables/etc. in the section will be evaluated taking into account the first dictionary. The second time, all variables/etc. will be evaluated taking into account the second dictionary. (See below for a definition of "taking into account.")

The value associated with a template-include is also a list of data dictionaries. Each data dictionary in this list must also have one other, mandatory associated piece of associated information: the filename of the template to include. At expand-time, that filename is passed as-is to ctemplate::ExpandTemplate() (or, more exactly, the equivalent of ExpandTemplate() in the same TemplateCache that the parent template comes from).

Details on Dictionary Lookup

The dictionary structure is a tree: there's a 'main' dictionary, and then a list of sub-dictionaries for each section or include-template. When looking up a marker -- be it a variable, section, or include-template marker -- the system looks in the currently applicable dictionary. If it's found there, that value is used. If not, and the parent dictionary is not an include-template, it continues the look in the parent dictionary, and possibly the grandparent, etc. That is, lookup has static scoping: you look in your dictionary and any parent dictionary that is associated with the same template-file. As soon as continuing the lookup would require you to jump to a new template-file (which is what include-template would do), we stop the lookup.

If lookup fails in all dictionaries, the template system does a final lookup in the global variable dictionary.

The system initializes the global dictionary with a few useful values for your convenience (the user can add more). All system variables are prefixed with BI, to emphasize they are "built in" variables.

  • BI_SPACE, which has the value <space>. It is used to force a space at the beginning or end of a line in the template, where it would normally be suppressed. (See below.)
  • BI_NEWLINE, which has the value <newline> It is used to force a newline at the end of a line, where it would normally be suppressed. (See below.)

Variable inheritance happens at expand time, not at dictionary-create time. So if you create a section dictionary, and then afterwards set a variable in its parent dictionary (or in the global dictionary), the section will inherit that variable value, if it doesn't define the value itself.

SetValue() and variants

SetValue() is used to set the value for a variable marker in a dictionary. It takes a string as input -- nominally a TemplateString, though a C++ string or C char* will be auto-converted -- for the variable name and its value. The name is the same string as is used for the variable's template-marker inside the template this dictionary will be expanded with: if the template reads Hello {{NAME}} then the first argument to SetValue() must be NAME. Case matters.

SetIntValue() takes an integer as the value, rather than a string. On all platforms, the integer may be up to 64 bits.

SetFormattedValue() is a convenience routine. SetFormattedValue(key, arg1, arg2, ...) is logically equivalent to

   char buffer[A_BIG_ENOUGH_NUMBER];
   sprintf(buffer, arg1, arg2, ...);
   SetValue(key, buffer);

without having to worry about the size of buffer, or about stack overflow.

SetValueWithoutCopy() is provided to give an extra bit of efficiency when needed. SetValue() will copy the key and value into an internal data structure used by the TemplateDictionary; this avoids dangling pointers if the arguments to SetValue() are temporaries, or otherwise have shorter lifetime than the TemplateDictionary. But if you know that both the key and value strings have lifetime longer than the TemplateDictionary -- perhaps because they are global (static duration) char*'s -- you can call SetValueWIthoutCopy() to avoid the copy. This yields a small time savings at the cost of significant code fragility, so should only be used when absolutely necessary.

SetGlobalValue() and SetTemplateGlobalValue()

SetGlobalValue() is like SetValue() but works on the global dictionary. Since the global dictionary is shared across all template dictionaries, this is a static method on TemplateDictionary. It is thread-safe. It is also relatively slow.

SetTemplateGlobalValue() is like SetValue(), but the values are preserved across template-includes.

This example shows all three forms:

A.tpl:
   {{NAME}} has won {{>PRIZE}}.  It is worth {{AMOUNT}}.
B.tpl:
   {{AMOUNT}} dollars!  And it's all yours, {{NAME}}
C.tpl:
   To: {{NAME}}.  Amount: {{AMOUNT}}.
code:
   ctemplate::TemplateDictionary dict("set_value_demo");
   ctemplate::TemplateDictionary* subdict = dict.AddIncludeDictionary("PRIZE");
   subdict->SetFilename("B.tpl");
   dict->SetValue("NAME", "Jane McJane");
   dict->SetTemplateGlobalValue("AMOUNT", "One Million");
   ctemplate::TemplateDictionary::SetGlobalValue("NAME", "John Doe");
   ctemplate::TemplateDictionary dict_c("set_value_demo, part 2");

   ctemplate::ExpandTemplate("A.tpl", ..., &dict);
   ctemplate::ExpandTemplate("C.tpl", ..., &dict_c);

The first expand yields this:

   Jane McJane has won One Million dollars!  And it's all yours, John Doe.  It is worth One Million.

The second expand yields this:

   To: John Doe.  Amount: .

NAME was set via SetValue(), so its value was not propagated across the include-dict boundary; instead, the subdict (B.tpl) got its value for NAME from the global dictionary. AMOUNT, on the other hand, was set via SetTemplateGlobalValue(), so its value was propagated across the boundary, and the subdict saw it. However, the totally unrelated template, C.tpl, did not see either value, and only sees the values in the global dictionary. (Of course, had we filled dict_c with some values, C.tpl would have had access to those.)

AddSectionDictionary(), ShowSection(), and SetValueAndShowSection()

AddSectionDictionary(section_name) returns a sub-dictionary associated with the given section_name (for instance, dict.AddSectionDictionary("MYSECT") for a template like {{#MYSECT}}...{{/MYSECT}}). If called multiple times, it will return a new dictionary each time. During Expand(), the section will be expanded once for each time AddSectionDictionary() was called; that is, the text inside the section delimiters will be repeated once for each AddSectionDictionary() call, and within a single repetition, the dictionary returned by AddSectionDictionary() will be used to populate the text inside the section delimiters. (With the current dictionary as that dictionary's parent, for inheritance purposes.)

This suggests that if AddSectionDictionary() is never called on a section, the text inside the section will be omitted entirely by Expand().

ShowSection() is a convenience method used to show the text inside the section exactly once. It is equivalent to calling AddSectionDictionary() once, and ignoring the returned sub-dictionary. All variables in the section will depend on dictionary inheritence to get their values.

SetValueAndShowSection() is another convenience method,, used to show a section if and only if a related variable is set to a non-empty value. SetValueAndShowSection(name, value, section_name) is equivalent to this: if value is empty do nothing, otherwise add a single dictionary to section_name and call section_dict->AddValue(name, value).

Example:

   ctemplate::TemplateDictionary* dict = new ctemplate::TemplateDictionary("section example");
   const char* username = GetUsername();   // returns "" for no user
   if (username[0] != '\0') {
      ctemplate::TemplateDictionary* sub_dict = dict->AddSectionDictionary("CHANGE_USER");
      sub_dict->SetValue("USERNAME", username);
   } else {
      // don't need to do anything; we want a hidden section, which is the default
   }

   // Instead of the above 'if' statement, we could have done this:
   if (username[0] != '\0') {
      dict->ShowSection("CHANGE_USER");       // adds a single, empty dictionary
      dict->SetValue("USERNAME", username);   // take advantage of inheritance
   } else {
      // don't need to do anything; we want a hidden section, which is the default
   }

   // Or we could have done this:
   dict->SetValueAndShowSection("USERNAME", username, "CHANGE_USER");

   // Moving on...
   GetPrevSearches(prev_searches, &num_prev_searches);
   if (num_prev_searches > 0) {
      for (int i = 0; i < num_prev_searches; ++i) {
         TemplateDictionary* sub_dict = dict->AddSectionDictionary("PREV_SEARCHES");
         sub_dict->SetValue("PREV_SEARCH", prev_searches[i]);
      }
   }

AddIncludeDictionary() and SetFilename()

AddIncludeDictionary(section_name) returns a sub-dictionary associated with the given include_name (for instance, dict.AddIncludeDictionary("MYTPL") for a template like {{>MYTPL}}). If called multiple times, it will return a new dictionary each time. It is the responsibility of the caller to then call SetFilename() on the sub-dictionary returned.

During Expand(), each dictionary returned by AddIncludeDictionary will be examined in turn. For each dictionary for which SetFilename() is called, that filename will be read as a template (via LoadTemplate(), with the same "strip" value as the current template), and expanded using the dictionary. (Note that the dictionary will not inherit SetValue() values from the parent dictionary, though it will inherit SetTemplateGlobalValue() values.) This expanded template will then be emitted to the output.

Note that if AddIncludeDictionary() is never called, the template-include will be a no-op during Expand(). Likewise, if it is called but SetFilename() is never called on the resulting sub-dictionary, the template-include will be a no-op. On the other hand, if it is called multiple times, multiple templates -- possibly all from the same file, possibly not -- will be inserted at the point of the template-include.

If a user has called StringToTemplateCache(key, ...), then the user can call SetFilename(key) to include the contents of the string as the sub-template.

Dump() and DumpToString()

These routines dump the contents of a dictionary and its sub-dictionaries. Dump() dumps to stdout, DumpToString() to a string. They are intended for debugging.

The TemplateCache Class

This class holds a collection of templates. It can be used to give you a coherent view of the template system: you load all the templates you are going to use into the cache, and then reload them from disk in one atomic operation. You can have multiple TemplateCache objects in your executable, perhaps one for each service you provide, or perhaps one per thread (so as to avoid thread contention when loading templates).

One intended use of the template cache is to make it safe to reload template files while serving user requests from a webserver. The idea is that every user request, as it's created, is associated with the current template cache. When you wish to reload, you Clone() the current cache, and then reload inside the cloned copy. New requests will get the cloned cache, while old requests will continue to render using the old cache. TemplateCache is written to make this use-case efficient: templates are shared between caches when appropriate, with reference-counting to keep memory management easy.

The default template cache

The template system creates a default template cache, which is available via the functions default_template_cache() and mutable_default_template_cache().

For simple uses of the template system, using the default cache, via ExpandTemplate() and the like, may be perfectly adequate. If you want more sophisticated features, such as the ability to have different versions of the same template file active at one time, or to change the template root-directory, you will have to use an explicit TemplateCache.

LoadTemplate() and StringToTemplateCache()

These two routines are how you explicitly insert data into the cache. LoadTemplate() reads a template from disk, while StringToTemplateCache() takes the data from a user-specified string. These work exactly the same as the global LoadTemplate() and StringToTemplateCache(), except they insert into the given TemplateCache, rather than the global cache.

LoadTemplate() is not strictly necessary: if the cache cannot find a template it needs at Expand*() time, it will automatically try to fetch it from disk. It is intended mostly for use with Freeze(), which disables this auto-fetch behavior.

Both of these routines take a strip mode specifying how the template system should treat whitespace while parsing.

If the template-cache is frozen, LoadTemplate() will only return true if the template is already stored in the cache, and will return false in every other case. For a frozen cache, StringToTemplateCache() will always return false.

ExpandWithData() and ExpandFrozen()

These routines takes a string that represents either a template filename (for disk-based templates), or a key used in StringToTemplateCache() (for string-based templates), a strip mode saying how to parse the template's whitespace, and per-expand data (which can be NULL). Overloads are provided to output the expanded template to either a string or to an arbitrary ExpandEmitter.

Expand uses the filename + strip pair to fetch the template from the cache, if it's there. If not, ExpandWithData() will fetch the template from disk and insert it into the cache. ExpandFrozen(), on the other hand, will just fail to expand, and return false. This is the only difference in behavior between the two routines. To reinforce this behavior, ExpandFrozen() will return false immediately if Freeze() has not been called on the cache.

While expanding, the template system may come across template sub-includes ({{>SUB_TEMPLATE}}). It will attempt to fetch these templates from the cache as well; failing that, it will try to load the template from disk (for ExpandWithData()) or else fail the expand and return false (for ExpandFrozen()).

Because ExpandFrozen() never updates the cache, it is a const method, unlike ExpandWithData().

Note that TemplateCache does not provide the convenience ExpandTemplate() routine, as the analogue of the global ExpandTemplate(). If you are not interested in the per-expand data, just call ExpandWithData() with the per-expand data set to NULL.

ReloadAllIfChanged()

For every file-based template in the cache (this method ignores string-based templates), ReloadAllIfChanged() checks the filesystem to see if the file has changed since it was loaded into the cache. If so, the cache loads a new version of the file into the cache. Note that at this point both the old and new versions of the file exist in the cache! Only the new version is accessible via new calls to Expand(), but any expansions currently in flight during the ReloadAllIfChanged() call will continue to use the old version.

NOTE: ReloadAllIfChanged() never modifies existing items in the cache in any way. It only loads new entries into the cache.

ReloadAllIfChanged() comes in two flavors, controlled by the passed-in enum. In "immediate" mode, it synchronously iterates through the cache and reloads all files that need it. In "lazy" mode, it waits to reload a given template file until the next time it's actually used (in a call to Expand*()). "Immediate" mode is safer in the case where templates depend on each other and the files change a lot, since all files are reloaded at about the same time. "Lazy" mode avoids the latency spike of "immediate" mode, and is preferable in the (common) case that files on disk change only rarely.

SetTemplateRootDirectory(), AddAlternateTemplateRootDirectory(), and template_root_directory()

By default, filenames passed in to Expand*() are taken to be relative to the current working directory. These functions change that behavior. SetTemplateRootDirectory() resets the search path to be the single path passed in to this function. Every time AddAlternateTemplateRootDirectory() is called, it adds another directory to the end of the search path. The template system will follow the search path, in order, when looking for a filename.

Note that the template search path is only meaningful when the filename passed to Expand*() (or specified for a sub-include) is a relative filename. If the filename is an absolute filename, starting with /, the search path is ignored.

template_root_directory() returns the first entry in the search path. There is currently no way to access other entries in the search path.

FindTemplateFilename()

FindTemplateFilename() does the work of finding a template file in the filesystem, using the current template search path. It takes a relative pathname as input, and returns an absolute pathname as output, indicating where the template file lives on the filesystem. If the template file is not found, this method returns the empty string.

Freeze()

Freeze() marks the template cache as immutable. After this method is called, the cache can no longer be modified by loading new templates or reloading existing templates. During expansion only cached included templates will be used; they won't be loaded on-demand.

Before calling Freeze(), you should make sure your cache has all the templates it might need, using LoadTemplate() and StringToTemplateCache(). Otherwise, ExpandWithData() and ExpandFrozen() may fail.

Once the cache is frozen, calls to SetTemplateRootDirectory(), AddAlternateTemplateRootDirectory(), Delete(), and ReloadAllIfChanged() will fail.

After the cache is frozen, the TemplateCache object is effectively const.

Delete()

This method deletes an entry from the cache. If the entry is in the cache multiple times (each with a different "strip" mode), this method deletes all of them.

ClearCache()

This method deletes all entries from the cache. It can be called even on a frozen cache.

Note: this method is not typically necessary unless you are testing for memory leaks. It is intended to be called just before exiting the program, and after all template expansions are completed. Using it in that way may prevent unnecessary reporting by the leak checker.

Clone()

Clone() makes a shallow copy of the given TemplateCache object, and returns the copy. The new copy and the old share the same template objects; since it's a shallow copy, they actually share pointers to the exact same object. (Since the template cache never changes a template object once it's loaded into the cache, sharing the pointer isn't a risk.)

The intended use of Clone(), as described above, is to allow fine control over "epochal" changes in templates. One TemplateCache can hold all versions of the template files before the big update; after the update is done, you can clone the old cache and then call ReloadAllIfChanged() on the clone. This is a low-cost operation, since the two copies share most resources. Smart pointers take care of most memory management issues.

The caller is responsible for calling delete on the returned TemplateCache object.

The TemplateNamelist Class

This class provides information about registered templates. Or more precisely, all templates corresponding to registered filenames.

All methods in this class are static.

RegisterTemplate() and RegisterTemplateFilename()

TemplateNamelist::RegisterTemplate() takes a filename and adds it to the static namelist used by TemplateNamelist. All other methods of TemplateNamelist work only on registered filenames.

It's fairly rare to call this method directly. Instead, the more common use is to use the macro RegisterTemplateFilename somewhere in the global scope, like so:

RegisterTemplateFilename(EXAMPLE_FN, "example.tpl");

The reason to prefer the macro is it defines a global variable that you can use instead of the hard-coded template name. This helps catch typos. The RegisterTemplateFilename() example is functionally equivalent to:

#define EXAMPLE_FN "example.tpl"

It can be used like this:

   ctemplate::ExpandTemplate(EXAMPLE_FN, ctemplate::DO_NOT_STRIP, ...);

GetMissingList()

TemplateNamelist::GetMissingList() returns a list of all registered templates (or rather, all filenames) where the file could not be found on disk.

AllDoExist()

Returns true if and only if the missing-list is empty.

GetBadSyntax()

Returns a list of all registered templates where the template contains a syntax error, and thus cannot be used.

IsAllSyntaxOkay()

True if and only if the bad-syntax list is empty.

GetLastmodTime()

Returns the latest last-modified time for any registered template-file.

The TemplateModifier Class and Associated Functions

A modifier is a filter that's applied at template-expand time, that munges the value of the variable before it's output. For instance, <html><body>{{NAME:html_escape}}</body></html> asks the template system to apply the built-in html_escape modifier when expanding {{NAME}}. If you set NAME in your dictionary to be Jim & Bob, what will actually be emitted in the template is Jim &amp; Bob.

You can chain modifiers together. This template first html-escapes NAME, and then javascript-escapes that result:

   <html><body>{{NAME:html_escape:javascript_escape}}</body></html>

Modifiers typically have a long, descriptive name and also a one-letter abbreviation. So this example is equivalent to the previous one:

   <html><body>{{NAME:h:j}}</body></html>

Some modifiers take an argument, specified after an equals sign:

   <html><body>{{NAME:html_escape_with_arg=pre}}</body></html>

Built-in Modifiers

Here are the modifiers that are built in to the template system. They are all defined in template_modifiers.cc:

long nameshort namedescription
:cleanse_css:c Removes characters not safe for a CSS value. Safe characters are alphanumeric, space, underscore, period, coma, exclamation mark, pound, percent, and dash.
:html_escape:h html-escapes the variable before output (eg & -> &amp;)
:html_escape_with_arg:H special purpose html escaping. See :H Arguments below for details.
:img_src_url_escape_with_arg:I special purpose image url escaping. See :I and :U Arguments below for details.
:javascript_escape:j javascript-escapes the variable before output (eg " -> \x27 and & -> \x26)
:javascript_escape_with_arg:J special purpose javascript escaping. See :J Arguments below for details.
:json_escape:o json-escapes a variable before output as a string in json; HTML characters are escaped using Unicode escape sequences (e.g & -> \u0026) to comply with RFC 4627.
:none leaves the variable as is (used to disable auto-escaping)
:pre_escape:p pre-escapes the variable before output (same as html_escape but whitespace is preserved; useful for <pre>...</pre>)
:url_escape_with_arg:U special purpose url escaping. See :I and :U Arguments below for details.
:url_query_escape:u performs URL escaping on the variable before output. space is turned into +, and everything other than [0-9a-zA-Z.,_:*/~!()-], is transformed into %-style escapes. Use this when you are building URLs with variables as parameters: 
<a href="http://google.com/search?q={{QUERY:u}}">{{QUERY:h}}</a>
:xml_escape xml-escapes the variable before output (the five characters <>&"' become &lt&gt;&amp;&quot;&#39;) suitable for content returned in raw XML. It is not intended for escaping content within CDATA blocks.

The *_with_arg modifiers require an argument to specify the type of escaping to use. The following sections list the supported arguments for each of these modifiers.

:H Arguments

Here are the values that are supported by the html_escape_with_arg modifier:

valuedescription
=snippet like html_escape, but allows HTML entities and some tags to pass through unchanged. The allowed tags are <br>, <wbr>, <b>, and </b>.
=pre same as pre_escape
=url same as :U=html below. For backwards compatibility.
=attribute replaces characters not safe for an use in an unquoted attribute with underscore. Safe characters are alphanumeric, underscore, dash, period, and colon.

:I and :U Arguments

Here are the values that are supported by the img_src_url_escape_with_arg and url_escape_with_arg modifiers:

valuedescription
=html Ensures that a variable contains a safe URL. Safe means that it is either a http or https URL, or else it has no protocol specified.
  • If the URL is safe, the modifier HTML-escapes the URL.
  • Otherwise, the modifier replaces the unsafe URL with one of the following values:
    • /images/cleardot.gif (the :I modifier)
    • # (the :U modifier)
Do not use :U for image URLs. Use :I instead. # is not a safe replacement for an image URL. <img src=#> can cause each browser to request the entire page again.
=javascript Same as =html, but using javascript escaping instead of html escaping.
=css Same as =html but using CSS escaping instead of html escaping so that the variable can be safely inserted within a CSS @import statement or a CSS property. The characters in [\r\n()'"<>*\] are transformed into %-style escapes.
=query (Supported for :U only) Same as url_query_escape.

:J Arguments

Here are the values that are supported by the javascript_escape_with_arg modifier:

valuedescription
=number Ensures that the variable is a valid number or boolean javascript literal. This includes booleans true and false, decimal numbers (e.g. 4.10 or -5.01e+10) as well as hex numbers (e.g. 0x5FF). This modifier is intended to ensure the variable not enclosed in quotes cannot contain javascript code that may execute. It does not guarantee that the variable is syntactically well-formed. If the variable is safe, it is returned as-is, otherwise it is replaced with null. In the future we may add more logic to support objects and arrays.

Custom Modifiers

In addition to the built-in modifiers, you can write your own modifier. Custom modifiers must have a name starting with "x-", and the name can contain alphanumeric characters plus dashes and underscores. Custom modifiers can also accept values with any character except for : and }. For example this template could be a valid use of a custom modifier:

{{VAR:x-my_modifier:value1,value2,value3 has spaces,etc}}

See <template_modifiers.h> for details on how to write a modifier and how to register it. In short, you write a modifier by subclassing ctemplate::TemplateModifier and overriding the Modify method, and you register it by calling ctemplate::AddModifier() Here is an example of the code for a custom modifier:

   class StarEscape : public ctemplate::TemplateModifier {
     void Modify(const char* in, size_t inlen,
                 const ctemplate::PerExpandData* per_expand_data,
                 ctemplate::ExpandEmitter* outbuf, const string& arg) const {
       outbuf->Emit(string("*") + string(in, inlen) + string("*"));
     }
   };

Subclassing TemplateModifier

The minimum work to create a custom modifier is to subclass TemplateModifier and override the Modify() method. Modify() takes as input the value of the text to be modified, as well as the per expand data associated with this Expand() call. The method may use this input, plus any other data it may have, to generate output, which it should write into the given ExpandEmitter.

The subclass can also override MightModify(). This is useful for modifiers that are typically a no-op (in which case the modifier is just doing busy-work, copying its input to the output ExpandEmitter). If MightModify() returns false, the template system will avoid calling Modify() at all on that variable, avoiding the busy-work copy.

AddModifier()

AddModifier() is used to register a custom modifier, so the modifier can be used in templates. The name of the modifier must start with x-.

AddXssSafeModifier()

AddXssSafeModifier() is used to register a custom modifier that can work well with the auto-escape system. It is used when the modifier produces output that is "safe" from cross-site scripting attacks in all contexts in which it might be used. For instance, a modifier that only emits numbers is xss-safe if it's only used in html or javascript contexts.

Auto-escaping and Manual Escaping

If the auto-escape pragma is used in a document, then all variables will be auto-escaped, even if explicit modifiers are used on the variable. The rules are a little complicated:

  • If the explicit modifier is a built-in modifier, and that modifier is "compatible" with the modifier that auto-escape would perform ("compatible" means it safely escapes in at least as many contexts as the auto-escape modifier), then only the explicit modifier is applied, and no further auto-escaping is done.
  • If the explicit modifier is a custom modifier registered using AddXssSafeModifier(), no further auto-escaping is done.
  • If the explicit modifier is the :none modifier, no further auto-escaping is done. This is the mechanism for manually turning off auto-escaping.
  • In all other situations, auto-escaping will be performed after the explicit modifiers have all run.

The PerExpandData Class

ExpandWithData() and TemplateModifier::Modify() both take a PerExpandData object. Per-expand data is applied to all templates that are seen while expanding: not only the template you called ExpandWithData() on, but also sub-templates that are brought in via template-includes ({{>INCLUDE}}).

There are several types of per-expand data you can set, by calling the appropriate method on a PerExpandData object.

SetAnnotateOutput()

This is a debugging function. When expanding this template, it adds marker-strings to the output to indicate what template-substitutions the system made. This takes a string argument which can be used to shorten the filenames printed in the annotations: if the filename contains the string you give, everything before that string is elided from the filename before printing. (It's safe to just always pass in the empty string.)

SetAnnotator()

This overrides the default text-based annotation used by SetAnnotateOutput(). If this is set and SetAnnotateOutput() is called, the per-expand data will use this TemplateAnnotator instance to do the annotation, rather than the default instance.

InsertForModifiers() and LookupForModifiers()

InsertForModifiers() stores an arbitrary key/value pair in the PerExpandData structure. This is used with template modifiers: the PerExpandData object passed to ExpandWithData() is made available to every template modifier that is called during expand time (including any custom modifiers). The intended use of this functionality is to allow a modifier to work one way when expanding a template with dictionary A, and another way when expanding a template with dictionary B. For instance, a modifier might encrypt part of a webpage using a user's secret-key, which is of course different for every expansion of the webpage.

LookupForModifiers() can be used by a template-modifier to read the key/value pair inserted by InsertForModifiers(). LookupForModifiersAsString() is the same, but returns the value as a char* rather than a void*, for convenience.

SetTemplateExpansionModifier()

This is an advanced feature for those who need a custom hook into template expansion. It will not be used by most programmers. It takes a template-modifier as its argument, but this template modifier is treated specially: instead of applying when an appropriate magic string appears in the text of a template, it applies every time a template is expanded during a call to ExpandWithData(). Note this means that it's called not only after the top-level template, that ExpandWithData() is called on, is expanded, but also on every sub-template that is expanded due to a template-include.

This unusual functionality has a few unusual properties. Since the template expansion modifier is not called in normal fashion, the normal arg argument to the template modifier does not make sense. Instead, the arg is set to the path of the template which is being expanded. Also, template expansion modifiers can be expensive, since they are applied pretty indiscriminately, so it can be worth implementing the MightModifiy() predicate for the passed-in TemplateModifier to avoid unnecessary work.

The TemplateAnnotator Class

The TemplateAnnotator class is used to pass in to PerExpandData::SetAnnotator(), to control how expand-time annotation is done. This is meant to be used as a debugging routine.

This class is an abstract base class; SetAnnotator() takes a subclass that implements the various methods of the base class. These methods control the action taken when various template markers are seen during template expansion.

template_annotator.h defines the abstract base class, and also a concrete subclass that is used by default for annotation if SetAnnotator() is not called.

The TemplateDictionaryPeer Class

By design, it is not possible to view the contents of a TemplateDictionary; we want to make sure the interface between the logic layer of the application and the presentation layer of the template goes in only one direction. While generally this keeps programs as clean as possible, it presents problems in testing code, which may want to verify that a given TemplateDictionary has been filled properly. The TemplateDictionaryPeer addresses this need. It lives in template_test_util.h.

Some of the methods of TemplateDictionaryPeer are useful for internal tests only. Below are some of the methods that are most useful for user-level tests.

STS_INIT_FOR_TEST

This macro allows use of STS_INIT for testing, even when the input pointer is not guaranteed to be allocated for the entire length of the test (it must, of course, be allocated for the entire lifetime of the template being tested). Since normally STS_INIT requires inputs to have static duration, this allows for more flexibility in tests, at the cost of worse memory management and decreased code safety (in that it's possible to accidentally violate the lifetime requirements).

GetSectionValue()

This returns the value for the named variable. It uses normal template scoping rules to resolve the name.

IsHiddenSection() and IsHiddenTemplate()

Checks if a section or sub-template is "hidden" (that is, won't be displayed at all).

GetSectionDictionaries() and GetIncludeDictionaries()

Returns all the sub-dictionaries for a given section or template-include, in a vector.

Other Testing Functions

template_test_util.h has other useful routines for testing, such as ExpandIs(), which tests whether a template + dictionary pair expands into an expected string. See the header file for details.

The ExpandEmitter Class

There are two overloads of ExpandTemplate(): the first emits the expanded template to a C++ string, and the second emits to an ExpandEmitter: an abstract base class that serves as a data source. It supports just one overloaded method, Emit(), that can take a char, a char*, or a C++ string as input.

Using this class requires subclassing ExpandEmitter and providing the various definitions for Emit(). For instance, a subclass might provide definitions of Emit() that send the input bytes out to a network socket.

In addition to defining the abstract base class, template_emitter.h provides a sample concrete subclass implementation, for emitting to a string.

The TemplateString and StaticTemplateString Classes

TemplateString is a string-like implementation. Ctemplate uses TemplateString almost exclusively, internally. Many of the public API methods, such as TemplateDictionary::SetValue(), also take TemplateString as input. TemplateString has implicit constructors for both C++ strings and char*'s, so every method that takes a TemplateString will also work if given a C++ string or a char*. If you have a char* and know its length, you can save a bit of work by explicitly constructing a TemplateString with a char* + length, for instance:

   dict->SetValue(ctemplate::TemplateString("MYVAR", 5), value);

Some compile-time tools work with TemplateString to offload computation from runtime to compile-time. This is possible because the Ctemplate code often stores a hash of a string rather than a string directly. For static, immutable strings, TemplateString can store a pre-computed hash value. This functionality is used by make_tpl_varnames_h. Thus, using this tool to create constants to use for SetValue() keys provides not only protection against typos, but a speed improvement as well.

For immutable strings in your code, you can create efficient compile-time template-string objects of your own -- in this case of type StaticTemplateString -- by using the STS_INIT macro, like so:

static const StaticTemplateString kSectName =
    STS_INIT(kSectName, "test_SetAddSectionDictionary");

The string variable's name, kSectName is repeated twice. The variable's value is specified inside the macro. Note that this macro should be used at the top level of a file, not inside functions (even when the variables are made static), and you should define the StaticTemplateString exactly as above: static const StaticTemplateString. Otherwise, the undefined constructor/destructor order of C++ may result in surprising behavior, wherein the StaticTemplateString is not initialized when it ought to be.

The Template Class

In older version of ctemplate, the Template class, which holds parsed templates, was a major part of the template workflow: the common template use-case would be:

   Template* tpl = Template::GetTemplate(filename, strip_mode);
   TemplateDictionary dict(name);
   tpl->Expand(&dict, &outstring);

In current use, this model is deprecated in favor of the single ExpandTemplate() call; support for Template methods may be removed entirely in future versions of ctemplate. However, you may still find older code using this old formulation.

Auto-Escaping

The Guide to using Auto Escape has an overview of Auto Escape as well as discussion of its limitations. To use it, put the following text at the top of the template:

  {{%AUTOESCAPE context="CONTEXT" [state="STATE"]}}

Description of the arguments:

  • The context attribute is one of HTML, JAVASCRIPT, CSS, JSON or XML. It must correspond to the context in which the browser will interpret this template. Warning: Setting the wrong context will result in wrong escaping applied to all variables in the given template. In particular, if the template starts with a <script> tag, its context is HTML and not JAVASCRIPT. Auto-Escape will recognize the <script> tag and hence properly Javascript-escape the variables within it. Similarly, if the template starts with a <style> tag, its context is HTML and not CSS.
  • The state attribute is commonly omitted. It accepts the value IN_TAG in the HTML context to indicate that the template only contains (one or more) HTML attribute name and value pairs that are part of an HTML tag formed in a parent template.

This will auto-escape every variable in the template. To turn off auto-escaping for a particular variable, you can apply the none modifier, like so: {{MYVAR:none}}. Here is an example of an autoescaped document:

  {{%AUTOESCAPE context="HTML"}}

  <body>
    <p>Hello {{USER}}</p>
    <p><a href="{{URL}}">Your Account</a></p>
    <p>Your identifier: {{ID:none}}{{! This is dangerous! }}</p>
  </body>

Development Tools

This package includes several tools to make it easier to use write and use templates.

make_tpl_varnames_h: Template Syntax Checker and Header File Generator

make_tpl_varnames_h is a "lint" style syntax checker and header file generator. It takes the names of template files as command line arguments and loads each file into a Template object by retrieving the file via the Template factory method. The loading of the file does pure syntax checking and reports such errors as mis-matched section start/end markers, mis-matched open/close double-curly braces, such as "{{VAR}", or invalid characters in template variables/names/comments.

If the template passes the syntax check, by default the utility then creates a header file for use in the executable code that fills the dictionary for the template. If the developer includes this header file, then constants in the header file may be referenced in the dictionary building function, rather than hard-coding strings as variable and section names. By using these constants, the compiler can notify the developer of spelling errors and mismatched names. Here's an example of how this is used, and how it helps prevent errors:

   const char * const kosr_RESULT_NUMBER = "RESULT_NUMBER";  // script output
   dict.SetValue("RESSULT_NUMBER", "4");    // typo is silently missed
   dict.SetValue(kosr_RESSULT_NUMBER, "4");   // compiler catches typo

Each constant is named as follows:

  • The initial letter 'k', indicating a defined constant.
  • One or more prefix letters which are derived from the template file name. These prefix letters consist of the first letter of the file name, followed by the first letter following each underscore in the name, with the exception of the letter 'p' when it is followed by the letters "ost", as is a recommended convention for template versioning. For example, the prefix letters for the file one_search_result_post20020815.tpl are osr.
  • An underscore.
  • The variable or section name itself, same casing.

As an example, the section name "RESULT_NUMBER" in the file one_search_result_post20020815.tpl would be given the constant name kosr_RESULT_NUMBER and would appear in the header file as const char * const kosr_RESULT_NUMBER = "RESULT_NUMBER"; -- as in the example above. (The variable is actually a StaticTemplateString, not a char*, but the basic idea holds.)

An alternate output directory may be specified by the command line flag --header_dir.

The name of the generated header file is the same as the name of the template file with an extension added to the name. By default, that extension is .varnames.h. In the above example, the header file containing the constant declarations would be named one_search_result_post20020815.tpl.varnames.h. An alternate extension may be provided via the command line flag --outputfile_suffix.

Important command line flags:

  • --noheader -- Indicates that a header file should not be generated; only syntax checking should be done.
  • --header_dir -- sets the directory where the header is written. Default: "./"
  • --template_dir -- sets the template root directory. Default: ./ which is the correct specification when it is run from the directory where the templates are located. This is only used if the input template filenames are specified as relative paths rather than absolute paths.
  • --outputfile_suffix -- the extension added to the name of the template file to create the name of the generated header file. Default: .varnames.h.

For a full list of command line flags, run make_tpl_varnames_h --help.

template-converter: convert a template to a C++ string

StringToTemplateCache() lets you load a template from a string instead of a file. Applications may prefer this option to reduce the dependencies of the executable, or use it in environments where data files are not practical. In such cases, template-converter can be used as a template "compiler", letting the developer write a template file as a data file in the normal way, and then "compiling" it to a C++ string to be included in the executable.

Usage is template-converter <template filename>. C++ code is output is to stdout; it can be stored in a .h file or included directly into a C++ file. Perl must be installed to use this script.

Tips and Guidelines for Using the Ctemplate System

(as of 10 March 2010)

The basic rules of the template system are enough to use it, but over time, we at Google have developed some tips, guidelines, and best practices that make it easier to use templates effectively, and to avoid common template errors.

Program Design Considerations

Template naming and versioning

Early in Google's use of templates, we noticed a problem: if a binary that uses a template and its corresponding template were both modified, particularly if the change were such that the old binary could not work with the new template or the new binary could not work with the old template, then somehow they both had to be deployed at the same instant to not present errors to our users. This was hard to do. The solution was to adopt a template naming and versioning convention. The procedure to use it follows:

  • Each template name ends with _postYYYYMMDD.tpl, where YYYMMDD is the date of this version's initial creation.
  • Before making (non-backward-compatible) modifications to a template, copy the template to a new name, incorporating a later date than the original one being copied.
  • Edit the new file, and push it to the production server.
  • Finally, update the code to refer to the new template-name (ideally, using the RegisterTemplateFilename idiom), and push the new executable to the production server.

When this convention is followed, the new template file does not overwrite the old one when it is deployed, because it is a new file with a new name. The old template file is still there to be used as long as the old binary is still in production and the new template file just sits there being ignored. Then when the new binary finally gets deployed, it immediately starts using the new template file, because it is coded (in RegisterTemplateFilename) to do so. After that, it is the old template file that continues to sit there ignored.

The make_tpl_varnames_h utility knows about the "_postYYYYMMDD" naming convention, so it is important that you use that convention exactly if you use the make_tpl_varnames_h.

Processing Phases

Typically a program using the Ctemplate System will perform the following phases, usually in this order:

  1. Retrieve and prepare the data used to fill a dictionary.
  2. Build the data dictionary, including all its sub-dictionaries, that will supply the values to the designated template object, its sections, and its included templates.
  3. Retrieve the top-level template object required to format the data. (This may or may not involve reading and parsing a template file, depending on whether the requested file has already been read and parsed by the running program or whether that file has been marked "reload if changed" and was in fact changed.)
  4. Expand the template object into an output buffer using the completed data dictionary.
  5. Output the buffer.
  6. Clean up: Destroy the top-level data dictionary whenever it is no longer needed.
  7. Optionally, clear the cache at the end of program execution.

One template / One procedure call

Most of the code of the program will be in Phases 1 and 2. Clearly, Phase 1 is outside the scope of the template system. But in designing the code for Phase 2 (building the data dictionary), it is wise to have the structure of the program reflect the structure of the templates being used. Specifically, there should be a single procedure call to build the dictionary for a single template. That procedure call should take parameters that include all the data required to populate the data dictionary for that template and all the templates it includes. Following this "one template/one procedure call" guideline further, for each included template, another procedure should be called to populate the (or each) data dictionary for that included template. This maintains the "one template/one procedure call" principle in a nested fashion that reflects the nesting of the templates.

This is not to imply that the "one procedure call" for a template should not be modularized into sub-procedures for readability and maintainability, or that it should not call other auxilliary procedures for such things as formatting the data and converting it to the appropriate strings, etc. But it does mean that there should be one entry point for building the dictionary tree for one template and that entry point should show the data dependencies of that template through its parameter list. This code for populating the data dictionary should NOT be intermingled with data gathering code that should have been done in Phase 1.

(Inside Google, the convention has been used to name the dictionary building procedure using the pattern fill_..._dictionary where the dots are related to the name of the template the data is being prepared for. For instance, the data for the template named one_search_result.tpl might be placed in a dictionary via a function named fill_one_search_result_dictionary.)

Tips, Idioms, and Conventions

  1. Choose template names to create unique constant prefixes.

    Template names should contain at least two words to avoid constant prefix clashes (e.g. kxy_ instead of kx_ ) The name of a new template should be checked against the existing names before proceeding. If your new template name produces a prefix that conflicts with an already existing template, you should change the name of your new template, even though it may be the only perfect name you can come up with. You'll have to use a less than perfect name in that case. (See "Template Syntax Checker and Header File Generator" below for more explanation about constant prefixes.)

  2. Use SetFormattedValue discriminately.

    This method should never be used to sneak HTML into the executable as in

         dictionary->SetFormattedValue(kxy_VAR,
                                   "<b>%s</b>",
                                   some_const_char_string);

    In that case, the <b> and </b> should be moved into the template.

  3. Never have a section encompass an entire template.

    If the first line of a template is a start section marker and the last line is its matching end section marker, then those markers are unnecessary in almost all cases. They are usually put there to allow the entire template to be hidden or iterated, but since it encompasses the entire file, the section may be hidden by not expanding the file (or by hiding the template-include section that includes the file) and it may be iterated by iterating the template-include marker of the including template. (The only exception might be if the entire page is to be iterated, but this seems a bit of a stretch.)

  4. An included template is just a section whose contents are located in a separate file. You may iterate over it just like you do sections.

    For example, if your template has the following template-include marker:

         {{>MY_INCLUDED_TEMPLATE}}

    you may call

         ctemplate::TemplateDictionary *child_dict =
        dictionary->AddIncludeDictionary(kxy_MY_INCLUDED_TEMPLATE);

    to iterate that section. (Note: Make sure you call child_dict->SetFilename()! If your included template is not showing in the output, this is the first thing you should check.)

  5. The recommended idiom to fill an include-template dictionary is like this: 
            fill_include_template_dictionary(dict->AddIncludeDictionary(name), ...);

    But what do you do if you decide, in fill_include_template_dictionary, that you don't want to display anything for this include-template after all? It seems like it's too late: you've already created the sub-dictionary. The solution is simple: just be sure that fill_include_template_dictionary() doesn't call SetFilename() in that case.

  6. Never have a section which only contains another section.

    For example, don't do this:

         {{#OUTER_SECTION}}
        {{#INNER_SECTION}}
        section contents here
        {{/INNER_SECTION}}
     {{/OUTER_SECTION}}

    or this equivalent template code (see the previous item):

         {{#OUTER_SECTION}}
        {{>INCLUDED_SECTION}}
     {{/OUTER_SECTION}}

    This is usually done because the developer thinks the outer section must be used to hide the section when the inner section, intended for iteration, has no iterations. In both cases, you should only have one section (either INNER_SECTION or INCLUDED_SECTION in the examples) and iterate that section either 0 times or more than 0 times. It's the wonder of the dual use of sections, i.e. that they may be conditional or iterative or, in this case, both.

    A related suggestion: Do not have a section whose entire contents is one variable marker with nothing else, unless you need to iterate over that section with multiple values of that variable. You don't need the surrounding section just to hide the marker. A variable marker that is not set, does not produce output. By convention, we set such variables to the empty string. But in neither case do you need to hide it by hiding a surrounding section that contains nothing else.

  7. Use this hide/show idiom for if-else blocks.

    Since sections are hidden by default, you can use represent if-else logic in your code via ShowSection. For example:

         if ( my_test ) {
        dict->ShowSection(kxyz_TRUE_BLOCK);
        [ more code to fill the values for that section]
     } else {
        dict->ShowSection(kxyz_FALSE_BLOCK);
        [ more code to fill the values for that section]
     }
  8. Write... vs. Fill...Dictionary methods - Observe the proper division of labor, don't mix them.

    The output (or write) function should create the top level template dictionary, call one or more fill-dictionary routines with it, then get the template and expand it. It should not call dictionary modifying methods, like ShowSection and SetValue. By keeping these separated into their own fill-dictionary routine, the code is more modular and lends itself to template re-use. If you maintain the proper division of labor, the template you are filling and outputting may be filled and included in a larger template by someone else.

  9. Use AddSectionDictionary only when you want to iterate over a section or, secondarily, if you need to avoid name conflicts.

    Sometimes developers get the idea that every section requires its own child dictionary created by an AddSectionDictionary call. Because of variable inheritence, this isn't usually so. The intended purpose of AddSectionDictionary is to enable iteration over a section. Secondarily, if the section contains generic names that may conflict with the same name in other parts of the template, it may be safer to call AddSectionDictionary to create a separate namespace. In any case, do not assume you must call AddSectionDictionary just because you are working within a section. The main dictionary can be used for all levels of conditional sections as long as you avoid name conflicts by keeping the marker names unique.

  10. Do not place RegisterTemplateFilename statements in header (.h) files.

    RegisterTemplateFilename is a macro that instantiates a TemplateNamelist object. If you place it in a header file, a different object will get created each time it is included in another .cc file.

    The RegisterTemplateFilename statement and its associated #include of the varnames.h file should occur only in the .cc file that implements the fill-dictionary routine for that template. You should never have more than one RegisterTemplateFilename for a single template and you should try hard not to copy the #include file to other files as well. The template versioning makes this more important because a developer may not know that the template name with included version number needs to be updated in more than one file when versioning occurs. [Also see above for more information about what routine uses the filename declared by the RegisterTemplateFilename statement.]

  11. Never reference more than one template in a fill...dictionary method.

    Each template should have its own fill-dictionary routine. That routine should only reference marker names defined in that template. If this convention is followed, then all the prefixes in a fill-dictionary routine will be the same. [Note that an implication of this convention is that if the template includes another template, via a template-include marker, then containing template's fill-dictionary routine should call the included template's fill-dictionary routine (being careful to observe the convention described above). But then, this is merely a restatement of "One template / One procedure call".]

  12. Have fill...dictionary call SetFilename even if the dictionary is never used for a template-include.

    SetFilename() is required when a dictionary is created via AddIncludeDictionary(). However, it's safe to set all the time. By setting it always, you make the code work properly if this dictionary ever changes to be template-included after all. Even if not, by saying what template file the dictionary is intended to go with, you are self-documenting your code.

  13. Do not call c_str() on strings to pass them to TemplateDictionary methods.

    Note that all the TemplateDictionary methods are defined to take TemplateString objects. These are created automatically from both strings and char*'s (and can be created manually if you have a char* and a length). So if you have a string, it's safe and efficient to just pass it in directly; you do not need to extract the const char * from your string object to pass it to these methods. For some reason, this is a common error of novice template coders.

    The one exception to this rule is when using the method SetFormattedValue. When calling that method, you must call c_str() on strings that are to be inserted into the format string, just as you would when providing data for any other printf format string.

  14. Do not use SetGlobalValue when you could use SetValue or SetTemplateGlobalValue.

    SetGlobalValue should be used quite rarely, for constants that really are consistent across all your templates. It's slower to look up a value in the global dictionary than it is in the template-specific dictionary.

  15. Do not use StringToTemplateCache unless you have a specific need for its non-file-based attributes.

    ctemplate::StringToTemplateCache was created for use in highly constrained cases where file I/O may be impaired or undesirable, for instance to produce a server error message where there may be disk problems or to produce formatted output where there are processes that do not have a facility for updating data files dynamically. It is not recommended for ordinary use since it cannot be updated dynamically via a data-push; changes always require a binary push.

  16. Use auto-escaping to prevent Cross-Site-Scripting security vulnerabilities.

    Use {{%AUTOESCAPE}} consistently. Use the :none modifier to override autoesacping only in those (usually rare) cases where there is a specific reason the template variable should not be escaped, for example:

    • The template variable contains HTML markup that should be interpreted by the browser. In this case you must be very careful to ensure that the variable can in no case contain "harmful" HTML. Also, keep in mind the above recommendation on the use of SetFormattedValue and consider moving the HTML markup into the template.
    • The variable is known to be already escaped at the point it is inserted into the template (for example, the value might be kept in escaped form in a storage backend). Here, escaping again via a variable-modifier would result in "double escaping". You must ensure that the variable comes escaped in the appropriate context (that is, if you're inserting the variable into an html document, it's html-escaped and not java-escaped).
  17. Do not leave an extra space when using {{BI_SPACE}}

    The built-in template variable BI_SPACE is itself replaced by a single space. It is used where you need to make sure a space is preserved at the end of a line. It is a common mistake to leave an extra space before this marker, which results in not one, but two, spaces created in the document.

    Incorrect:

    <table border=0 {{BI_SPACE}}
       align=center>

    Correct:

    <table border=0{{BI_SPACE}}
       align=center>

Cross-Site Scripting Resources

Status: Current   (as of 17 August 2006)

Cross-Site Scripting (commonly abbreviated as XSS) is a security issue that arises when an attacker can cause client-side script (such as JavaScript) of his or her choosing to execute within another user's browser in the context of a given web-site or web-application. This may allow the attacker to steal that user's session cookies for the web-application in question, or otherwise manipulate that user's session context.

XSS vulnerabilities most often arise if a web-application renders data that originated from an untrusted source (such as a query parameter) in a HTML document without carefully validating or escaping that data.

The following online resources provide further information on XSS vulnerabilities and how to avoid them:

(The user can also force certain dnl compiler flags/libs to be tested by setting these environment dnl variables.) dnl dnl Also sets PTHREAD_CC to any special C compiler that is needed for dnl multi-threaded programs (defaults to the value of CC otherwise). dnl (This is necessary on AIX to use the special cc_r compiler alias.) dnl dnl NOTE: You are assumed to not only compile your program with these dnl flags, but also link it with them as well. e.g. you should link dnl with $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS dnl $LIBS dnl dnl If you are only building threads programs, you may wish to use dnl these variables in your default LIBS, CFLAGS, and CC: dnl dnl LIBS="$PTHREAD_LIBS $LIBS" dnl CFLAGS="$CFLAGS $PTHREAD_CFLAGS" dnl CC="$PTHREAD_CC" dnl dnl In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute dnl constant has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to dnl that name (e.g. PTHREAD_CREATE_UNDETACHED on AIX). dnl dnl ACTION-IF-FOUND is a list of shell commands to run if a threads dnl library is found, and ACTION-IF-NOT-FOUND is a list of commands to dnl run it if it is not found. If ACTION-IF-FOUND is not specified, the dnl default action will define HAVE_PTHREAD. dnl dnl Please let the authors know if this macro fails on any platform, or dnl if you have any other suggestions or comments. This macro was based dnl on work by SGJ on autoconf scripts for FFTW (www.fftw.org) (with dnl help from M.

Here's one way to do it: // UnsafeArena* arena = new UnsafeArena(1000); // or SafeArena(), or 10000 // vector > v(arena); // // Note that every STL type always allows the allocator (in this case, // the arena, which is automatically promoted to an allocator) as the last // arg to the constructor.

Doing this the usual way (malloc, new) is slow, // especially for multithreaded programs. A BaseArena provides a // mark/release method of memory management: it asks for a large chunk // from the operating system and doles it out bit by bit as required. // Then you free all the memory at once by calling BaseArena::Reset(). // // Use SafeArena for multi-threaded programs where multiple threads // could access the same arena at once. Use UnsafeArena otherwise. // Usually you'll want UnsafeArena. // // There are four ways to use the arena. arena.h and arena.cc are // sufficient for the MALLOC and STRINGS uses. For NEW and STL you'll // also need to include arena-inl.h in the appropriate .cc file. // However, we do *declare* (but not define) the template types here. // // LIKE MALLOC: --Uses UnsafeArena (or SafeArena)-- // This is the simplest way. Just create an arena, and whenever you // need a block of memory to put something in, call BaseArena::Alloc(). eg // s = arena.Alloc(100); // snprintf(s, 100, "%s:%d", host, port); // arena.Shrink(strlen(s)+1); // optional; see below for use // // You'll probably use the convenience routines more often: // s = arena.Strdup(host); // a copy of host lives in the arena // s = arena.Strndup(host, 100); // we guarantee to NUL-terminate! // s = arena.Memdup(protobuf, sizeof(protobuf); // // If you go the Alloc() route, you'll probably allocate too-much-space. // You can reclaim the extra space by calling Shrink() before the next // Alloc() (or Strdup(), or whatever), with the #bytes you actually used. // If you use this method, memory management is easy: just call Alloc() // and friends a lot, and call Reset() when you're done with the data. // // FOR STRINGS: --Uses UnsafeArena (or SafeArena)-- // This is a special case of STL (below), but is simpler. Use an // astring, which acts like a string but allocates from the passed-in // arena: // astring s(arena); // or "sastring" to use a SafeArena // s.assign(host); // astring s2(host, hostlen, arena); // // WITH NEW: --Uses BaseArena, Gladiator (or ArenaOnlyGladiator)-- // Use this to allocate a C++ class object (or any other object you // have to get via new/delete rather than malloc/free). // There are several things you have to do in this case: // 1) Your class (the one you new) must inherit from Gladiator. // 2) To actually allocate this class on the arena, use // myclass = new (AllocateInArena, arena) MyClass(constructor, args) // // Note that MyClass doesn't need to have the arena passed in. // But if it, in turn, wants to call "new" on some of its member // variables, and you want those member vars to be on the arena // too, you better pass in an arena so it can call new(0,arena). // // If you can guarantee that everyone who ever calls new on // MyClass uses the new(0,arena) form (ie nobody ever just says // new), you can have MyClass subclass from ArenaOnlyGladiator // rather than from Gladiator. ArenaOnlyGladiator is a bit more // efficient (faster and smaller), but is otherwise identical. // // If you allocate myclass using new(0,arena), and MyClass only // does memory management in the destructor, it's not necessary // to even call "delete myclass;", you can just call arena.Reset(); // If the destructor does something else (closes a file, logs // a message, whatever), you'll have to call destructor and Reset() // both: "delete myclass; arena.Reset();" // // Note that you can not allocate an array of classes this way: // noway = new (AllocateInArena, arena) MyClass[5]; // not supported! // It's not difficult to program, we just haven't done it. Arrays // are typically big and so there's little point to arena-izing them. // // WITH NEW: --Uses UnsafeArena-- // There are cases where you can't inherit the class from Gladiator, // or inheriting would be too expensive. Examples of this include // plain-old-data (allocated using new) and third-party classes (such // as STL containers). arena-inl.h provides a global operator new // that can be used as follows: // // #include "base/arena-inl.h" // // UnsafeArena arena(1000); // Foo* foo = new (AllocateInArena, &arena) Foo; // Foo* foo_array = new (AllocateInArena, &arena) Foo[10]; // // IN STL: --Uses BaseArena, ArenaAllocator-- // All STL containers (vector, hash_map, etc) take an allocator. // You can use the arena as an allocator. Then whenever the vector // (or whatever) wants to allocate memory, it will take it from the // arena. To use, you just indicate in the type that you want to use the // arena, and then actually give a pointer to the arena as the last // constructor arg: // vector > v(&arena); // v.push_back(3); // // WARNING: Careless use of STL within an arena-allocated object can // result in memory leaks if you rely on arena.Reset() to free // memory and do not call the object destructor. This is actually // a subclass of a more general hazard: If an arena-allocated // object creates (and owns) objects that are not also // arena-allocated, then the creating object must have a // destructor that deletes them, or they will not be deleted. // However, since the outer object is arena allocated, it's easy to // forget to call delete on it, and needing to do so may seem to // negate much of the benefit of arena allocation. A specific // example is use of vector in an arena-allocated object, // since type string is not atomic and is always allocated by the // default runtime allocator. The arena definition provided here // allows for much flexibility, but you ought to carefully consider // before defining arena-allocated objects which in turn create // non-arena allocated objects. // // WITH HANDLES: // The various arena classes can supply compact handles to data kept // in the arena. These handles consume only 4 bytes each, and are thus // more efficient than pointers - this may be interesting in cases // where a very large number of references to memory in the arena need // to be kept. // Note that handles are limited in the amount of data that can be reference // in the arena, typically to 4GB*the number given to set_handle_alignment() // (which defaults to 1). The number of allocations that can have handles // is, of course, smaller than 4G (that's what's representable by 32 bits). // It does depend on their sizes, however. In a worst-case scenario each // allocation consumes a page of its own, and we will run out of handles // after approximately (4G/block_size)*handle_alignment allocations. // When we run out of handles or allocate data over the amount of memory // that handles can reference, an invalid handle will be returned (but // the requested memory will still be allocated in the arena). // Handles memory use is most efficient when the arena block size is a power // of two. When this is not the case, we can run out of handles when at // most half of the addressable space (as described above) is not in use. // At worst handles can reference at least 2GB*handle_alignment. // Example use: // UnsafeArena arena(16384); // arena.set_handle_alignment(4); // // Assume you want to keep the string s in the arena. // Handle h = arena.MemdupWithHandle(s.c_str(), s.length()); // // Later, to get the memory from the handle, use: // void* p = arena.HandleToPointer(h); // // Note that there's no way to retrieve the size from the handle. // // It probably makes sense to encode the size into the buffer saved, // // unless the size is known/fixed. // Internal machinery of handles: // The handle consists of the block index in the arena and the offset // inside the block, encoded into a single unsigned uint32 value. // Note that, the rightmost alignment bits (controlled by // set_handle_alignment()) are shaved off the saved offset in the Handle, // to give some extra capacity :) // set_handle_alignment() can only be called when the arena is empty, // as changing it invalidates any handles that are still in flight. // // // PUTTING IT ALL TOGETHER // Here's a program that uses all of the above. Note almost all the // examples are the various ways to use "new" and STL. Using the // malloc-like features and the string type are much easier! // // Class A : public Gladiator { // public: // int i; // vector v1; // vector >* v3; // vector >* v4; // vector* v5; // vector vs; // vector va; // char *s; // A() : v1(), v3(NULL), v4(NULL), vs(), va(), s(NULL) { // // v1 is allocated on the arena whenever A is.

The issue in this case is that // dynamic-initialization happens in an unpredictable order, and it // could be that someone else's dynamic initializer could call a // function that tries to acquire this mutex -- but that all happens // before this mutex's constructor has run. (This can happen even if // the mutex and the function that uses the mutex are in the same .cc // file.) Basically, because Mutex does non-trivial work in its // constructor, it's not, in the naive implementation, safe to use // before dynamic initialization has run on it. // // The solution used here is to pair the actual mutex primitive with a // bool that is set to true when the mutex is dynamically initialized. // (Before that it's false.) Then we modify all mutex routines to // look at the bool, and not try to lock/unlock until the bool makes // it to true (which happens after the Mutex constructor has run.) // // This works because before main() starts -- particularly, during // dynamic initialization -- there are no threads, so a) it's ok that // the mutex operations are a no-op, since we don't need locking then // anyway; and b) we can be quite confident our bool won't change // state between a call to Lock() and a call to Unlock() (that would // require a global constructor in one translation unit to call Lock() // and another global constructor in another translation unit to call // Unlock() later, which is pretty perverse). // // That said, it's tricky, and can conceivably fail; it's safest to // avoid trying to acquire a mutex in a global constructor, if you // can. One way it can fail is that a really smart compiler might // initialize the bool to true at static-initialization time (too // early) rather than at dynamic-initialization time. To discourage // that, we set is_safe_ to true in code (not the constructor // colon-initializer) and set it to true via a function that always // evaluates to true, but that the compiler can't know always // evaluates to true. This should be good enough. // // A related issue is code that could try to access the mutex // after it's been destroyed in the global destructors (because // the Mutex global destructor runs before some other global // destructor, that tries to acquire the mutex). The way we // deal with this is by taking a constructor arg that global // mutexes should pass in, that causes the destructor to do no // work. We still depend on the compiler not doing anything // weird to a Mutex's memory after it is destroyed, but for a // static global variable, that's pretty safe. #ifndef GOOGLE_MUTEX_H_ #define GOOGLE_MUTEX_H_ #include #if defined(NO_THREADS) typedef int MutexType; // to keep a lock-count #elif defined(_WIN32) || defined(__CYGWIN32__) || defined(__CYGWIN64__) # ifndef WIN32_LEAN_AND_MEAN # define WIN32_LEAN_AND_MEAN // We only need minimal includes # endif # ifndef NOMINMAX # define NOMINMAX // Don't want windows to override min()/max() # endif # ifdef GMUTEX_TRYLOCK // We need Windows NT or later for TryEnterCriticalSection().

Its purpose is to scan an html stream and provide context information at any point within the input stream. This is used in the auto escaping functionality of the templating system, which would require html context information at very specific points within the html stream. The implementation is based on a simplified state machine of HTML4.1. The implementation is written in C, with the idea of making is usable in other contexts besides this html paresr; however, we compile all the files as c++ files in order to be able to use a namespace (and avoid global namespace pollution).

If we * get a match on any of these keywords, then we are opening a regular * expression, if not, then we have a division operator. * * Known cases that are accepted by the grammar but we handle differently, * although I don't believe there is a legitimate usage for those: * * Division of a regular expression: * var result = /test/ / 5; * * Prefix unary increment of a regular expression: * var result = ++/test/; * * Division of an object literal: * { a: 1 } /x/.exec('x'); * * We only support ascii right now, so unicode characters in identifiers will * be treated as delimiters, effectively breaking the identifier name where * they appear, and this may cause issues in very specific situations. Namely, * if we have a unicode character in an identifier directly preceding a suffix * that matches one of the keywords in regexp_token_prefix[], if this * identifier precedes a / (slash) character: * * var x = testreturn / 5; * * We will interpret that slash as the start of a regular expression, when in * reality it is a division operator. */ static void enter_state_js_slash(statemachine_ctx *ctx, int start, char chr, int end) { jsparser_ctx *js; char buffer[JSPARSER_RING_BUFFER_SIZE]; int pos; assert(ctx != NULL); assert(ctx->user != NULL); js = CAST(jsparser_ctx *, ctx->user); assert(js != NULL); pos = -1; /* Consume the last whitespace. */ if (js_is_whitespace(jsparser_buffer_get(js, pos))) { --pos; } switch (jsparser_buffer_get(js, pos)) { /* Ignore unary increment */ case '+': if (jsparser_buffer_get(js, pos - 1) != '+') { ctx->next_state = JSPARSER_STATE_INT_JS_REGEXP_SLASH; } break; /* Ignore unary decrement */ case '-': if (jsparser_buffer_get(js, pos - 1) != '-') { ctx->next_state = JSPARSER_STATE_INT_JS_REGEXP_SLASH; } break; /* List of punctuator endings except ), ], }, + and - */ case '=': case '<': case '>': case '&': case '|': case '!': case '%': case '*': case '/': case ',': case ';': case '?': case ':': case '^': case '~': case '{': case '(': case '[': case '}': case '\0': ctx->next_state = JSPARSER_STATE_INT_JS_REGEXP_SLASH; break; default: if (jsparser_buffer_last_identifier(js, buffer) && is_regexp_token_prefix(buffer)) { ctx->next_state = JSPARSER_STATE_INT_JS_REGEXP_SLASH; } } jsparser_buffer_append_chr(js, chr); } /* Called at the end of a javascript comment. * * When we open a comment, the initial '/' was inserted into the ring buffer, * but it is not a token and should be considered whitespace for parsing * purposes. * * When we first saw the '/' character, we didn't yet know if it was the * beginning of a comment, a division operator, or a regexp. * * In this function we just replace the inital '/' with a whitespace character, * unless we had a preceding whitespace character, in which case we just remove * the '/'.
