It is compiled into libintl when the included GNU gettext library is configured --with-included-gettext. This redirection works also in the case that the system C library or the system libintl library contain gettext/textdomain/... functions. If it didn't, we would need to add preprocessor level redirections to libgnuintl.h of the following form: # define gettext gettext__ # define dgettext dgettext__ # define dcgettext dcgettext__ # define ngettext ngettext__ # define dngettext dngettext__ # define dcngettext dcngettext__ # define textdomain textdomain__ # define bindtextdomain bindtextdomain__ # define bind_textdomain_codeset bind_textdomain_codeset__ How does this redirection work? There are two cases. A. When libintl.a is linked into an executable, it works because functions defined in the executable always override functions in the shared libraries. B. When libintl.so is used, it works because 1. those systems defining gettext/textdomain/... in the C library (namely, Solaris 2.4 and newer, and GNU libc 2.0 and newer) are ELF systems and define these symbols as weak, thus explicitly letting other shared libraries override it. 2. those systems defining gettext/textdomain/... in a standalone libintl.so library (namely, Solaris 2.3 and newer) have this shared library in /usr/lib, and the linker will search /usr/lib *after* the directory where the GNU gettext library is installed. A third case, namely when libintl.a is linked into a shared library whose name is not libintl.so, is not supported. In this case, on Solaris, when -lintl precedes the linker option for the shared library containing GNU gettext, the system's gettext would indeed override the GNU gettext. Anyone doing this kind of stuff must be clever enough to 1. compile libintl.a with -fPIC, 2. remove -lintl from his linker command line. */ #undef gettext #undef dgettext #undef dcgettext #undef ngettext #undef dngettext #undef dcngettext #undef textdomain #undef bindtextdomain #undef bind_textdomain_codeset char * gettext (msgid) const char *msgid; { return gettext__ (msgid); } char * dgettext (domainname, msgid) const char *domainname; const char *msgid; { return dgettext__ (domainname, msgid); } char * dcgettext (domainname, msgid, category) const char *domainname; const char *msgid; int category; { return dcgettext__ (domainname, msgid, category); } char * ngettext (msgid1, msgid2, n) const char *msgid1; const char *msgid2; unsigned long int n; { return ngettext__ (msgid1, msgid2, n); } char * dngettext (domainname, msgid1, msgid2, n) const char *domainname; const char *msgid1; const char *msgid2; unsigned long int n; { return dngettext__ (domainname, msgid1, msgid2, n); } char * dcngettext (domainname, msgid1, msgid2, n, category) const char *domainname; const char *msgid1; const char *msgid2; unsigned long int n; int category; { return dcngettext__ (domainname, msgid1, msgid2, n, category); } char * textdomain (domainname) const char *domainname; { return textdomain__ (domainname); } char * bindtextdomain (domainname, dirname) const char *domainname; const char *dirname; { return bindtextdomain__ (domainname, dirname); } char * bind_textdomain_codeset (domainname, codeset) const char *domainname; const char *codeset; { return bind_textdomain_codeset__ (domainname, codeset); } mp4h-1.3.1/intl/plural.c0000644000175000017500000010011707502457424010467 /* A Bison parser, made from plural.y by GNU Bison version 1.28 */ #define YYBISON 1 /* Identify Bison output. */ #define yyparse __gettextparse #define yylex __gettextlex #define yyerror __gettexterror #define yylval __gettextlval #define yychar __gettextchar #define yydebug __gettextdebug #define yynerrs __gettextnerrs #define EQUOP2 257 #define CMPOP2 258 #define ADDOP2 259 #define MULOP2 260 #define NUMBER 261 #line 1 "plural.y" /* Expression parsing for plural form selection.

See the COPYING file for details. ---------------- Mp4h is a text processor specifically designed for HTML documents. It has two ancestors: Meta-HTML and GNU m4 . The former inspired mp4h syntax whereas source code is derived from the latter. Mp4h syntax is immediately familiar to HTML programmers. Users can define their own tags, and programming constructs like loops, arrays, conditionals make mp4h very powerful. Mp4h is extendable to fit every needs. It can of course load new macro definitions put in package files, but also dynamically load shared libraries containing compiled macro definitions. -- Denis Barbier mp4h-1.3.1/ABOUT-NLS0000644000175000017500000004464407502457421007316 Notes on the Free Translation Project ************************************* Free software is going international! The Free Translation Project is a way to get maintainers of free software, translators, and users all together, so that will gradually become able to speak many languages. A few packages already provide translations for their messages. If you found this `ABOUT-NLS' file inside a distribution, you may assume that the distributed package does use GNU `gettext' internally, itself available at your nearest GNU archive site. But you do _not_ need to install GNU `gettext' prior to configuring, installing or using this package with messages translated. Installers will find here some useful hints. These notes also explain how users should proceed for getting the programs to use the available translations. They tell how people wanting to contribute and work at translations should contact the appropriate team. When reporting bugs in the `intl/' directory or bugs which may be related to internationalization, you should tell about the version of `gettext' which is used. The information can be found in the `intl/VERSION' file, in internationalized packages. Quick configuration advice ========================== If you want to exploit the full power of internationalization, you should configure it using ./configure --with-included-gettext to force usage of internationalizing routines provided within this package, despite the existence of internationalizing capabilities in the operating system where this package is being installed. So far, only the `gettext' implementation in the GNU C library version 2 provides as many features (such as locale alias, message inheritance, automatic charset conversion or plural form handling) as the implementation here. It is also not possible to offer this additional functionality on top of a `catgets' implementation. Future versions of GNU `gettext' will very likely convey even more functionality. So it might be a good idea to change to GNU `gettext' as soon as possible. So you need _not_ provide this option if you are using GNU libc 2 or you have installed a recent copy of the GNU gettext package with the included `libintl'. INSTALL Matters =============== Some packages are "localizable" when properly installed; the programs they contain can be made to speak your own native language. Most such packages use GNU `gettext'. Other packages have their own ways to internationalization, predating GNU `gettext'. By default, this package will be installed to allow translation of messages. It will automatically detect whether the system already provides the GNU `gettext' functions. If not, the GNU `gettext' own library will be used. This library is wholly contained within this package, usually in the `intl/' subdirectory, so prior installation of the GNU `gettext' package is _not_ required. Installers may use special options at configuration time for changing the default behaviour. The commands: ./configure --with-included-gettext ./configure --disable-nls will respectively bypass any pre-existing `gettext' to use the internationalizing routines provided within this package, or else, _totally_ disable translation of messages. When you already have GNU `gettext' installed on your system and run configure without an option for your new package, `configure' will probably detect the previously built and installed `libintl.a' file and will decide to use this. This might be not what is desirable. You should use the more recent version of the GNU `gettext' library. I.e. if the file `intl/VERSION' shows that the library which comes with this package is more recent, you should use ./configure --with-included-gettext to prevent auto-detection. The configuration process will not test for the `catgets' function and therefore it will not be used. The reason is that even an emulation of `gettext' on top of `catgets' could not provide all the extensions of the GNU `gettext' library. Internationalized packages have usually many `po/LL.po' files, where LL gives an ISO 639 two-letter code identifying the language. Unless translations have been forbidden at `configure' time by using the `--disable-nls' switch, all available translations are installed together with the package. However, the environment variable `LINGUAS' may be set, prior to configuration, to limit the installed set. `LINGUAS' should then contain a space separated list of two-letter codes, stating which languages are allowed. Using This Package ================== As a user, if your language has been installed for this package, you only have to set the `LANG' environment variable to the appropriate `LL_CC' combination. Here `LL' is an ISO 639 two-letter language code, and `CC' is an ISO 3166 two-letter country code. For example, let's suppose that you speak German and live in Germany. At the shell prompt, merely execute `setenv LANG de_DE' (in `csh'), `export LANG; LANG=de_DE' (in `sh') or `export LANG=de_DE' (in `bash'). This can be done from your `.login' or `.profile' file, once and for all. You might think that the country code specification is redundant. But in fact, some languages have dialects in different countries. For example, `de_AT' is used for Austria, and `pt_BR' for Brazil. The country code serves to distinguish the dialects. Not all programs have translations for all languages. By default, an English message is shown in place of a nonexistent translation. If you understand other languages, you can set up a priority list of languages. This is done through a different environment variable, called `LANGUAGE'. GNU `gettext' gives preference to `LANGUAGE' over `LANG' for the purpose of message handling, but you still need to have `LANG' set to the primary language; this is required by other parts of the system libraries. For example, some Swedish users who would rather read translations in German than English for when Swedish is not available, set `LANGUAGE' to `sv:de' while leaving `LANG' to `sv_SE'. In the `LANGUAGE' environment variable, but not in the `LANG' environment variable, `LL_CC' combinations can be abbreviated as `LL' to denote the language's main dialect. For example, `de' is equivalent to `de_DE' (German as spoken in Germany), and `pt' to `pt_PT' (Portuguese as spoken in Portugal) in this context. Translating Teams ================= For the Free Translation Project to be a success, we need interested people who like their own language and write it well, and who are also able to synergize with other translators speaking the same language. Each translation team has its own mailing list. The up-to-date list of teams can be found at the Free Translation Project's homepage, `http://www.iro.umontreal.ca/contrib/po/HTML/', in the "National teams" area. If you'd like to volunteer to _work_ at translating messages, you should become a member of the translating team for your own language. The subscribing address is _not_ the same as the list itself, it has `-request' appended. For example, speakers of Swedish can send a message to `sv-request@li.org', having this message body: subscribe Keep in mind that team members are expected to participate _actively_ in translations, or at solving translational difficulties, rather than merely lurking around. If your team does not exist yet and you want to start one, or if you are unsure about what to do or how to get started, please write to `translation@iro.umontreal.ca' to reach the coordinator for all translator teams. The English team is special. It works at improving and uniformizing the terminology in use. Proven linguistic skill are praised more than programming skill, here. Available Packages ================== Languages are not equally supported in all packages. The following matrix shows the current state of internationalization, as of September 2001. The matrix shows, in regard of each package, for which languages PO files have been submitted to translation coordination, with a translation percentage of at least 50%.

This is because a few extra PO files are used for implementing regional variants of languages, or language dialects. For a PO file in the matrix above to be effective, the package to which it applies should also have been internationalized and distributed as such by its maintainer. There might be an observable lag between the mere existence a PO file and its wide availability in a distribution. If September 2001 seems to be old, you may fetch a more recent copy of this `ABOUT-NLS' file on most GNU archive sites. The most up-to-date matrix with full percentage details can be found at `http://www.iro.umontreal.ca/contrib/po/HTML/matrix.html'. Using `gettext' in new packages =============================== If you are writing a freely available program and want to internationalize it you are welcome to use GNU `gettext' in your package. Of course you have to respect the GNU Library General Public License which covers the use of the GNU `gettext' library. This means in particular that even non-free programs can use `libintl' as a shared library, whereas only free software can use `libintl' as a static library or use modified versions of `libintl'. Once the sources are changed appropriately and the setup can handle to use of `gettext' the only thing missing are the translations. The Free Translation Project is also available for packages which are not developed inside the GNU project. Therefore the information given above applies also for every other Free Software Project. Contact `translation@iro.umontreal.ca' to make the `.pot' files available to the translation teams. mp4h-1.3.1/COPYING0000664000175000017500000004312707021016044007103 GNU GENERAL PUBLIC LICENSE Version 2, June 1991 Copyright (C) 1989, 1991 Free Software Foundation, Inc. 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found.

The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker. , 1 April 1989 Ty Coon, President of Vice This General Public License does not permit incorporating your program into proprietary programs.

Take this logfile for concrete and detailed information about every single change. ___________________________________________________________________________ Changes between 1.3.0 and 1.3.1: *) Fix uninitialized variables in source code (10-Jan-2003): The LAST_CHAR macro must not be applied to a null string. Fortunately there does not seem to cause trouble here. [Denis Barbier] *) Fix (18-Oct-2002): Remove trailing newline. [Ralf Vissers ] *) Fix memory error in (27-Sep-2002): Some argument checks were missing in and could cause memory fault. [Jean-Michel Sauvage ] Changes between 1.2.4 and 1.3.0: *) Replace configure flag about modules (06-Jul-2002): The --enable-modules flag is replaced by --with-modules, ans it now takes an optional argument which is the list of modules to install. [Denis Barbier] *) New tag (04-Jul-2002): It currently supports %s flag character, with $ extension. [Denis Barbier] *) Improve debugging for module loading (01-Jul-2002): The new -dm debugging flag gives information when loading modules. [Denis Barbier] *) Revamp module management (19-Jun-2002): Modules and packages are extensions for mp4h. The former refered to shared libraries whereas the latter contain macros. Modules are loaded with tag, and packages via the tag. But this is confusing, because user had to know module internals to determine how to call it. These notions are now merged: every module must also have an associated package file, whose only task is to load shared library. Thus end-user only calls macro, and is hidden. the MP4HLIB environment variable may be used to set run-time search paths. [Denis Barbier] *) Use Automake (16-Jun-2002): Eventually Automake is back. [Denis Barbier] *) Add support for i18n (16-Jun-2002): Add gettext support. [Denis Barbier] *) Upgrade to PCRE 3.9 (15-Jun-2002): [Denis Barbier] *) Add intl:gettext module (13-Jun-2002): This module is an interface for gettext functions. [Denis Barbier] *) Fix module detection (18-Mar-2002): There were several bugs which caused failure when multiple paths were defined in MP4HMODPATH. [Denis Barbier] *) Upgraded to GNU shtool 1.6.0 (06-Mar-2002): [Denis Barbier] *) Fix literals (06-Mar-2002): mp4h 1.2.4 does not handle <@[ ]@> quotes as expected, they were simply discarded. [Denis Barbier] Changes between 1.2.3 and 1.2.4: *) Run autoconf in libltdl/ subdirectory (02-Mar-2002): The toplevel configure script could fail due to autoconf version mismatch. [Guido Draheim ] *) Fix and tags (11-Jan-2002): Valueless attributes in these tags crashed mp4h. [Anders Dinsen] *) Do not abort with missing input files (05-Jan-2002): Just print a warning and skip this file. [Anders Dinsen] *) Fix line numbers in error messages (10-Dec-2001): [Denis Barbier] *) Upgrade to PCRE 3.7 (08-Nov-2001): Upstream do allow various definitions of newline char, I keep stuck with `\n' in internal.h until I know exactly how to incorporate this option. [Denis Barbier] Changes between 1.2.2 and 1.2.3: *) Fix leading space added by (25-Oct-2001): This space must not be added when attribute is empty. [Denis Barbier] Changes between 1.2.1 and 1.2.2: *) Leading space added by (18-Oct-2001): This tag is useful for printing HTML output. This change allows writing > which prints without attributes and instead. It is now much more user friendly because there is no need to first check whether there are attributes in order to decide to add a leading space or not. [Denis Barbier] *) Change in handling invalid negative array indices (17-Oct-2001): They have now no effect, they did formerly reset variable. [Denis Barbier] *) Checks added for preserve/restore pairs (17-Oct-2001): A warning is raised at end of processing when some material remains on this stack. [Denis Barbier] *) Fix memory leaks (15-Oct-2001): [Denis Barbier] *) Fix arrays (15-Oct-2001): Insertion of values inside arrays did fail under some circumstance. [Ghislaine Labouret ] Changes between 1.2.0 and 1.2.1: *) Add support for case sensitiveness (30-Sep-2001): In HTML, tags are case insensitive unlike entities. Moreover in XHTML, tags have also become case sensitive. For these reasons, it is important to be able to decide at run time whether symbols are case sensitive or not. A new -c flag does the job. [Denis Barbier] *) Improve documentation (29-Sep-2001): Entities are now used in place of some tags, and some typos are fixed. [Anders Dinsen] *) Implement entity support (28-Sep-2001): [Anders Dinsen] *) Minor change in top level Makefile.in (26-Aug-2001): The `clean' and `distclean' targets are unconditionnally processed through the modules/ directory. [Denis Barbier] *) Fix version number in documentation (26-Aug-2001): [Denis Barbier] Changes between 1.1.2 and 1.2.0: *) Allow compilation from another directory (14-Aug-2001): Makefiles are updated to allow compilation from another directory, when `make' supports the VPATH feature. [Denis Barbier] *) Clean up configure.ac (14-Aug-2001): The new AC_INIT form in Autoconf 2.50 does now its job, and version number is retrieved from src/version.c. This was not as easy as with Autoconf 2.13, I hope this is the canonical way to insert some code to run before AC_INIT. [Denis Barbier] *) Install libraries in subdirectories (13-Aug-2001): As with , double colons are replaced by slashes in attributes, which allows putting libraries in subdirectories. [Denis Barbier] *) Upgrade to Autoconf 2.50 (12-Aug-2001): [Denis Barbier] *) Change invocation (12-Aug-2001): Module name must now be set through `name' attribute. [Denis Barbier] *) Internal naming changes in src/builtin.c (11-Aug-2001): Future versions will be more modularized, and some care must be taken with naming conventions; more functions and variables will be prefixed by `mp4h_', so all functions called by predefined macros are renamed from mp4h_ to mp4h_bp_ to clearly identify builtin primitives. [Denis Barbier] *) Experimental UTF-8 support (21-Jul-2001): Compile PCRE 3.4 with UTF-8 support, A new --encoding option accepts 2 values, either `8bit' or `utf8'. When `utf8' is selected, regular expressions are compiled with PCRE_UTF8 flag. The and tags are also encoding-dependent. [Denis Barbier] *) Upgrade to PCRE 3.4 (21-Jul-2000): [Denis Barbier] *) Fix (21-Apr-2001): A segmentation fault occurred when uid or gid could not be resolved. [Denis Barbier] *) Change module invocation (07-Apr-2001): The tag is replaced by a more generic tag, which works with shared library and mp4h modules. [Denis Barbier] *) Rearrange modules/ subdirectory (07-Apr-2001): [Denis Barbier] *) New tag (24-Mar-2001): Like , but this is a complex tag. [Anders Dinsen] *) New tag (24-Mar-2001): Returns absolute pathname of a file. [Anders Dinsen] *) Clean-up src/builtin.c (24-Mar-2001): The mp4h_set_var_verbatim function is useless and removed. [Anders Dinsen] *) Fix compilation on Tru64 (24-Mar-2001): [Stéphane Bortzmeyer] *) Improve tag (14-Mar-2001): File name is passed through the `file' attribute, and a new `command' attribute allows reading output from arbitrary shell command. As this might be considered as a security flaw, a new -S flag allows filtering potentially risky functions. [Anders Dinsen] *) Add diversions (09-Mar-2001): Push diversion mechanisms back into mp4h. [Anders Dinsen] *) Improve tag (09-Mar-2001): New `time' and `format' attributes make this tag much more powerful. [Anders Dinsen ] *) Remove special characters in debugging output (20-Feb-2001): [Axel Beckert ] *) New tag (20-Feb-2001): This tag does the opposite job of , it explodes its attribute into several pieces. [Denis Barbier] *) Fix bug with body tag surrounded by quotes (20-Feb-2001): When a body function was surrounded within double quotes (without any whitespace around), it was simply discarded. [Petr Andreyev ] Changes between 1.1.1 and 1.1.2: *) Fix bugs with conditionals (07-Nov-2000): The , and conditionals do not behave properly. Under rare circumstances, both THEN and ELSE clauses may be run. [Martin Schulze ] Changes between 1.1.0 and 1.1.1: *) Fix trailing slash in empty complex tags (31-Aug-2000): They caused memory errors. [Denis Barbier] *) Fix bugs with non-ASCII letters (31-Aug-2000): Mp4h gobbled some non-ASCII letters because of misuse of signedness. Several similar bugs have been fixed. [Denis Barbier, Debian webmasters] *) Upgraded to GNU shtool 1.5.1 (08-Aug-2000): Upgraded to GNU shtool 1.5.1. This especially fixed problems with "shtool version" under Solaris. [Ralf S. Engelschall] Changes between 1.0.6 and 1.1.0: *) Rename option to disable support for loadable modules (24-Jul-2000): This option is now `./configure --disable-modules' [Denis Barbier] *) New -X option (21-Jul-2000): With -X=32, a trailing slash is appended to simple tag attributes. For readibility and to follow appendix C of the XHTML 1.0 specifications, a space is inserted before this trailing slash. When value 256 is also set, this space is not inserted. [Denis Barbier] *) Add support for modifiers in regexps (21-Jul-2000): Only i, m, s and x modifiers have been added, U and X are specific to PCRE and have not been implemented. The `singleline' attribute has been changed. It now accepts two values, `true' (like the s modifier) and `false' (like the m modifier). Until now, `m' was the default, and singleline=true switches to `s'. [Denis Barbier] *) Clean Up in PCRE files (21-Jul-2000): Only used files are kept back. [Denis Barbier] *) Use of the native API of PCRE (21-Jul-2000): And support for locales has been added. Mp4h is now fully powered by PCRE. [Denis Barbier] Changes between 1.0.5 and 1.0.6: *) Use of the PCRE library (20-Jul-2000): This library is copyrighted by University of Cambridge. With this library, Perl regular expressions may now be used instead of POSIX regular expressions. Current implementation in mp4h is quite weak, because we use the POSIX compatibility mode instead of native API. Moreover one test of the test suite fails. [Denis Barbier] *) Fix some bugs with quotes (19-Jul-2000): Quotes have two functions: group multiple words into a single token in attributes, and its normal meaning (i.e. output quotes). The former must be removed, whereas the latter are preserved. This is quite tricky, and previous implementations failed under certain circumstances. Now when quotes are seen outside of tag attributes, they are marked as being special and cannot be removed. The tag is also fixed. [Fritz Zaucker] *) Add support for loadable modules (12-Jul-2000): This stage was easy because GNU m4 1.4n already has such support. Work has to be done to provide a nice API to module developers. [Denis Barbier] *) Allow trailing slash in empty complex tags (12-Jul-2000): It is now possible to write even if `foo' has been declared as being complex. [Denis Barbier] *) Fix driver for Info documentation (11-Jul-2000): This driver is just an example to determine if it is worth trying to write Info files. [Denis Barbier] *) Forbid negative indices in arrays (11-Jul-2000): A negative index returns an empty value. [Denis Barbier] *) Improve and (10-Jul-2000): These functions now accept matches against regular expressions, and new examples in documentation explain how to define a macro which may pass its attributes to HTML tags. [Denis Barbier] *) Fix `beginning of line' bug in regular expressions (09-Jul-2000): The `^' special character was not interpreted. [Denis Barbier] Changes between 1.0.4 and 1.0.5: *) Minor fix to restore compatibility with old syntax (09-Jul-2000): It is possible (but not desirable) to put square brackets after a variable name to show that this variable is an array of newline separated lists. This fix restores this capability which is broken in 1.0.4 [Denis Barbier] Changes between 1.0.3 and 1.0.4: *) Internal change in hash tables (08-Jul-2000): Until now, variables and macros shared the same hash table. They now have their own tables, which should speed up symbol searches. A new table is used to store names of loaded package files, in order to prevent loading a file more than once. [Denis Barbier] *) Add support for third-party packages (08-Jul-2000): The new tag is similar to the synonym Perl command. Files are searched in directories specified with the -I command-line flag, then in directories listed in MP4HPATH if this environment variable exists, last under /usr/local/share/mp4h (or any other location specified at configure time). Package files have a .mp4hp suffix, which is removed when calling . If filename contains colons, they are replaced by slashes and so represent directory names. [Denis Barbier] *) Internal changes about regular expressions (06-Jul-2000): Mp4h now uses the POSIX functions of the GNU libc regex.c instead of old GNU functions. The most important reason for this change is that previous functions are not documented, and so hard to maintain. Moreover i had to patch the regex functions to allow the ``singleline=true'' attribute. With this new version it works out of the box, and many memory leaks are also fixed. [Denis Barbier] *) Restore grouping around (06-Jul-2000): Like other tags, did not group its expansion into a single token. It does now, because it seems that it is more useful in general cases. [Denis Barbier] *) Fix boolean operators (05-Jul-2000): The tag was broken, and has been cleaned up. [Denis Barbier] *) Improve / stuff (05-Jul-2000): These tags accept now any number of arguments, so it is possible to write ... code using `name', `src' and `text' variables. [Denis Barbier] *) Better control with tag (04-Jul-2000): With `up=0', closes all current macro expansion. With `up=-1', closes all current macro expansion and stops processing current file. [Denis Barbier] *) Preserve whitespaces in attributes (04-Jul-2000): Meta-HTML did preserve whitespaces in attributes. Even if it is not very useful, some people may need this feature to format thier output files as wanted. This change fixes also the `whitespace=delete' attribute, which did remove newlines in attributes. [Denis Barbier] *) Fix (04-Jul-2000): This tag could cause segmentation fault. [Denis Barbier] *) New tag for grouping (02-Jul-2000): It does exactly the same job as , but this tag is complex. [Denis Barbier] *) New tags to affect attributes (01-Jul-2000): The and tags allow extraction and removal of specific attributes from %attributes. And prints the list of attributes with quotes around attribute values. [Denis Barbier, Ralf S. Engelschall] *) Reintroduce support for dmalloc (28-Jun-2000): Original m4 sources provide support for dmalloc, a great malloc debugger. This support is activated via the --with-dmalloc flag at configure time. [Denis Barbier] Changes between 1.0.2 and 1.0.3: *) Fix localization (26-Jun-2000): Localization was not fully effective because it uses some internal tables which were not updated when l10n is modified. [Denis Barbier] *) Fix non-ASCII characters (26-Jun-2000): Previous versions of mp4h had some problem of endianness, which may occur with non-ASCII text. [Max H. Duenki ] *) Fix frozen state files mechanism (24-Jun-2000): Frozen state files are unusable in mp4h-1.0.2. [Denis Barbier] *) Parse bad formed closing tags (24-Jun-2000): With previous versions, closing tags with attributes confuse mp4h. They are now accepted, even if not desirable in input files. [Fritz Zaucker ] Changes between 1.0.1 and 1.0.2: *) Improve output routines (22-Jun-2000): Changes are performed to remove some unused garbage. [Denis Barbier] *) Fix verbatim inclusion of files by mp4h (22-Jun-2000): An endianness problem caused unexpected results when including files verbatim. And text included this way could not appear inside other tags. Both problems have been solved. [Denis Barbier] Changes between 1.0.0 and 1.0.1: *) Fix '<*' form on some platforms (21-Jun-2000): At least on SunOS, an error is reported under some circumstances. [Denis Barbier] Changes between 0.9.5 and 1.0.0: *) Numerous clean-ups and documentation enhancements (19-Jun-2000): Macro parser is now very robust, and extensible with the -X flag. It should be useful to any HTML (or XHTML) writer which wants a simple but powerful macro-processor. Documentation is enhanced, but need some more work. Expansion behaviour has been deeply reviewed since 0.9.5, see documentation for details. [Denis Barbier] *) Change expansion flags (18-Jun-2000): Two flags have been switched, and two new options added to remove leading and trailing star in tag names. [Denis Barbier] *) Change valid tag names (17-Jun-2000): Valid tag names now match [a-zA-Z_][a-zA-Z_0-9:-]* Previous versions also accept `%' sign, which is removed not to conflict with ASP notation. [Denis Barbier] *) Remove control characters from debug output (16-Jun-2000): There were some garbage in debug output caused by control characters, which are now filtered. [Denis Barbier] *) Fix string substitution (14-Jun-2000): With some complex expressions, string substitution did not work properly. [Denis Barbier] *) Fix logical operators (14-Jun-2000): With some complex expressions, , and logical operators did not work properly. [Denis Barbier] *) Change default behaviour (13-Jun-2000): The removal of trailing star in tag name is suppressed, because it cannot deal with all cases. The only right approach is to use a post-processor (this brilliant thought has changed on 18-Jun-2000). Escaping mechanism has also been reviewed. [Denis Barbier] *) Remove French documentation (07-Jun-2000): English version is now the only one maintained. [Denis Barbier] *) Remove trailing star in tag name (04-Jun-2000): Because of new parsing scheme, complex HTML tags must be well nested. When this is not the case, e.g. only begin or end tag is to be processed, there must be a way to let mp4h believe that following tag is simple without putting a trailing slash in attributes. This is done by appending a star to the tag name, both in begin and end tag. This star is automatically removed. [Denis Barbier] *) New tags added (04-Jun-2000): Tags , , and allow protection of the following special characters: `<', `>', '"' and '\'. [Denis Barbier] *) Add -X flag to test parser (03-Jun-2000): [Denis Barbier] *) Fix compilation bug in src/builtin.c (01-Jun-2000): [] *) Provide a way to read tokens without parsing (01-Jun-2000): All characters between <@[ and ]@> are read without parsing, this is very useful to read malformed mp4h tags. These delimiters may be changed with the tag. [Tobias Oetiker ] Changes between 0.9.4 and 0.9.5: *) Change evaluation of unknown tags (22-May-2000): Until now, unknown tags were treated like normal text, i.e. left angle bracket lose their special meaning. This has very strange side effects when such tags appear in attributes. [many people] *) Fix trailing slash (06-May-2000): When there was no attribute and no space before the slash sign, as in
, this tag was not expanded. [Denis Barbier] Changes between 0.9.3 and 0.9.4: *) Changes in l10n (03-May-2000): I do not know how to deal with locales in a portable way, so examples are removed from documentation. Only English documentation is build, but you may continue to compile the French one if your environment variables are rightly set. [Denis Barbier] *) Syntax change in the tag (03-May-2000): New syntax is , similar to TeX and more user friendly. [Denis Barbier] Changes between 0.9.2 and 0.9.3: *) Ease building of Debian package (20-Apr-2000): I added a new `deb' target to build Debian packages [Denis Barbier] *) Do not invoke tidy on HTML documentation (20-Apr-2000): By default HTML documentation is no more post-processed by tidy because some old versions break compilation. This feature is available with the --with-tidy flag of the configure script. [Ralf S. Engelschall] *) Fix compilation on some platforms (20-Apr-2000): [Stephane Bortzmeyer ] *) Better handling of trailing slashes (20-Apr-2000): Now a trailing slash in is not removed [Nobuyuki Tsuchimura] Changes between 0.9.1 and 0.9.2: *) New array-topvalue tag (18-Apr-2000): This tag prints the last entry in an array. [Denis Barbier] *) Better handling of trailing slashes (18-Apr-2000): It was very difficult to prevent suppression of trailing slash in attributes. Now it can be done by putting spaces between this slash and the closing bracket. [Nobuyuki Tsuchimura] *) Many cosmetic changes (13-Apr-2000): Mp4h is now spelled mp4h in lowercase letters in all files. Some source files are fixed to produce no warning at compilation time. [Ralf S. Engelschall] Changes between 0.9.0 and 0.9.1: *) Fix bugs with extra quotes in attributes (03-Apr-2000): [Denis Barbier] *) Fix bugs in grouping (03-Apr-2000): [Denis Barbier] *) Remove a trailing slash in attributes (01-Apr-2000): When reading attributes of single tags, a trailing slash is ignored. [Denis Barbier] Changes between 0.8.5 and 0.9.0: *) Customization of number output format (01-Apr-2000): [Denis Barbier] *) Add support for localization (01-Apr-2000): New macro defines locale settings. By default, locale is set to C. [Denis Barbier] *) Change arguments of array functions (01-Apr-2000): To be more intuitive, first argument of all array-related macros is now the name of the variable containing the array. [Denis Barbier] *) Change some array functions (31-Mar-2000): The tag is replaced by and is added. [Denis Barbier] *) Implicit array indexes (29-Mar-2000): The expression is a shorthand for ]>. [Jan Holler ] *) Fix warning messages (29-Mar-2000): [Denis Barbier] Changes between 0.8.5 and 0.8.4: *) Fix bug with some nested expressions (27-Mar-2000): [Nobuyuki Tsuchimura ] Changes between 0.8.4 and 0.8.3: *) Change in grouping (25-Mar-2000): The quoted=true attribute of the tag is removed and this feature is now provided by the tag.

[Denis Barbier] mp4h 0.7.0 (11-Feb-2000): First public release. mp4h-1.3.1/INSTALL0000664000175000017500000001723007021016044007075 Basic Installation ================== These are generic installation instructions. 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, a file `config.cache' that saves the results of its tests to speed up reconfiguring, and a file `config.log' containing compiler output (useful mainly for debugging `configure'). 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 at some point `config.cache' contains results you don't want to keep, you may remove or edit it. The file `configure.in' is used to create `configure' by a program called `autoconf'. You only need `configure.in' 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. If you're using `csh' on an old version of System V, you might need to type `sh ./configure' instead to prevent `csh' from trying to execute `configure' itself. Running `configure' takes awhile. 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. Compilers and Options ===================== Some systems require unusual options for compilation or linking that the `configure' script does not know about. You can give `configure' initial values for variables by setting them in the environment. Using a Bourne-compatible shell, you can do that on the command line like this: CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure Or on systems that have the `env' program, you can do it like this: env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure 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 must use a version of `make' that supports the `VPATH' variable, such as 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 `..'. If you have to use a `make' that does not supports the `VPATH' variable, you have 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' will install the package's files in `/usr/local/bin', `/usr/local/man', etc. You can specify an installation prefix other than `/usr/local' by giving `configure' the option `--prefix=PATH'. You can specify separate installation prefixes for architecture-specific files and architecture-independent files. If you give `configure' the option `--exec-prefix=PATH', the package will use PATH as the prefix for installing programs and libraries. Documentation and other data files will still use the regular prefix. In addition, if you use an unusual directory layout you can give options like `--bindir=PATH' 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' can not figure out automatically, but needs to determine by the type of host the package will run on. Usually `configure' can figure that out, but if it prints a message saying it can not guess the host type, give it the `--host=TYPE' option. TYPE can either be a short name for the system type, such as `sun4', or a canonical name with three fields: CPU-COMPANY-SYSTEM 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 host type. If you are building compiler tools for cross-compiling, you can also use the `--target=TYPE' option to select the type of system they will produce code for and the `--build=TYPE' option to select the type of system on which you are compiling the package. 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. Operation Controls ================== `configure' recognizes the following options to control how it operates. `--cache-file=FILE' Use and save the results of the tests in FILE instead of `./config.cache'. Set FILE to `/dev/null' to disable caching, for debugging `configure'. `--help' Print a summary of the options to `configure', and exit. `--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. `--version' Print the version of Autoconf used to generate the `configure' script, and exit. `configure' also accepts some other, not widely useful, options. mp4h-1.3.1/Makefile.am0000664000175000017500000000135007545134401010105 AUTOMAKE_OPTIONS = foreign DIST_SUBDIRS = intl pcre lib src po doc modules tests if LOADABLE_MODULES SUBDIRS = intl pcre lib src po doc modules tests else SUBDIRS = intl pcre lib src po doc tests endif EXTRA_DIST = CREDITS README README.pcre bootstrap.sh shtool deb: if test -f ../mp4h_$(VERSION).orig.tar.gz; then \ :; \ else \ $(MAKE) dist && mv mp4h-$(VERSION).tar.gz ../mp4h_$(VERSION).orig.tar.gz; \ fi -rm -rf config.log autom4te.cache $(MAKE) distclean && dpkg-buildpackage -i'/CVS|/\.cvsignore|/\.scvsrc|/tags' -rfakeroot README: configure.ac src/readme.tmpl @x='@'; sed -e "s/$${x}PACKAGE_VERSION$${x}/@PACKAGE_VERSION@/" -e "s/$${x}PACKAGE_DATE$${x}/@PACKAGE_DATE@/" src/readme.tmpl > $@ mp4h-1.3.1/Makefile.in0000664000175000017500000003572207610120044010117 # Makefile.in generated by automake 1.6.3 from Makefile.am. # @configure_input@ # Copyright 1994, 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002 # Free Software Foundation, Inc. # This Makefile.in is free software; the Free Software Foundation # gives unlimited permission to copy and/or distribute it, # with or without modifications, as long as this notice is preserved. # This program is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY, to the extent permitted by law; without # even the implied warranty of MERCHANTABILITY or FITNESS FOR A # PARTICULAR PURPOSE. @SET_MAKE@ SHELL = @SHELL@ srcdir = @srcdir@ top_srcdir = @top_srcdir@ VPATH = @srcdir@ prefix = @prefix@ exec_prefix = @exec_prefix@ bindir = @bindir@ sbindir = @sbindir@ libexecdir = @libexecdir@ datadir = @datadir@ sysconfdir = @sysconfdir@ sharedstatedir = @sharedstatedir@ localstatedir = @localstatedir@ libdir = @libdir@ infodir = @infodir@ mandir = @mandir@ includedir = @includedir@ oldincludedir = /usr/include pkgdatadir = $(datadir)/@PACKAGE@ pkglibdir = $(libdir)/@PACKAGE@ pkgincludedir = $(includedir)/@PACKAGE@ top_builddir = .

The dnl default (if it is not specified or empty) is 'no-libtool'. dnl INTLSYMBOL should be 'external' for packages with no intl directory, dnl and 'no-libtool' or 'use-libtool' for packages with an intl directory. dnl If INTLSYMBOL is 'use-libtool', then a libtool library dnl $(top_builddir)/intl/libintl.la will be created (shared and/or static, dnl depending on --{enable,disable}-{shared,static} and on the presence of dnl AM-DISABLE-SHARED).

If NEEDSYMBOL is specified and is dnl 'need-formatstring-macros', then GNU gettext implementations that don't dnl support the ISO C 99 formatstring macros will be ignored. dnl INTLDIR is used to find the intl libraries.

Here is a matrix of mmap possibilities: mmap private not fixed mmap private fixed at somewhere currently unmapped mmap private fixed at somewhere already mapped mmap shared not fixed mmap shared fixed at somewhere currently unmapped mmap shared fixed at somewhere already mapped For private mappings, we should verify that changes cannot be read() back from the file, nor mmap's back from the file at a different address. (There have been systems where private was not correctly implemented like the infamous i386 svr4.0, and systems where the VM page cache was not coherent with the file system buffer cache like early versions of FreeBSD and possibly contemporary NetBSD.) For shared mappings, we should conversely verify that changes get propagated back to all the places they're supposed to be. Grep wants private fixed already mapped.

The idea is that you would use these pre-tested macros to solve a very specific set of problems, and they would run fast. Caution: no side-effects in arguments please!! They may be evaluated MANY times!! These macros operate a stack of objects. Each object starts life small, and may grow to maturity. (Consider building a word syllable by syllable.) An object can move while it is growing. Once it has been "finished" it never changes address again. So the "top of the stack" is typically an immature growing object, while the rest of the stack is of mature, fixed size and fixed address objects. These routines grab large chunks of memory, using a function you supply, called `obstack_chunk_alloc'. On occasion, they free chunks, by calling `obstack_chunk_free'. You must define them and declare them before using any obstack macros. Each independent stack is represented by a `struct obstack'. Each of the obstack macros expects a pointer to such a structure as the first argument. One motivation for this package is the problem of growing char strings in symbol tables. Unless you are "fascist pig with a read-only mind" --Gosper's immortal quote from HAKMEM item 154, out of context--you would not like to put any arbitrary upper limit on the length of your symbols. In practice this often means you will build many short symbols and a few long symbols. At the time you are reading a symbol you don't know how long it is. One traditional method is to read a symbol into a buffer, realloc()ating the buffer every time you try to read a symbol that is longer than the buffer. This is beaut, but you still will want to copy the symbol from the buffer to a more permanent symbol-table entry say about half the time. With obstacks, you can work differently. Use one obstack for all symbol names. As you read a symbol, grow the name in the obstack gradually. When the name is complete, finalize it. Then, if the symbol exists already, free the newly read name. The way we do this is to take a large chunk, allocating memory from low addresses. When you want to build a symbol in the chunk you just add chars above the current "high water mark" in the chunk. When you have finished adding chars, because you got to the end of the symbol, you know how long the chars are, and you can create a new object. Mostly the chars will not burst over the highest address of the chunk, because you would typically expect a chunk to be (say) 100 times as long as an average object. In case that isn't clear, when we have enough chars to make up the object, THEY ARE ALREADY CONTIGUOUS IN THE CHUNK (guaranteed) so we just point to it where it lies. No moving of chars is needed and this is the second win: potentially long strings need never be explicitly shuffled. Once an object is formed, it does not change its address during its lifetime. When the chars burst over a chunk boundary, we allocate a larger chunk, and then copy the partly formed object from the end of the old chunk to the beginning of the new larger chunk. We then carry on accreting characters to the end of the object as we normally would. A special macro is provided to add a single char at a time to a growing object. This allows the use of register variables, which break the ordinary 'growth' macro. Summary: We allocate large chunks. We carve out one object at a time from the current chunk. Once carved, an object never moves. We are free to append data of any size to the currently growing object. Exactly one object is growing in an obstack at any one time. You can run one obstack per control block. You may have as many control blocks as you dare. Because of the way we do it, you can `unwind' an obstack back to a previous state.

[This is the first released version of the library GPL. It is numbered 2 because it goes with version 2 of the ordinary GPL.] Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public Licenses are intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This license, the Library General Public License, applies to some specially designated Free Software Foundation software, and to any other libraries whose authors decide to use it. You can use it for your libraries, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the library, or if you modify it. For example, if you distribute copies of the library, whether gratis or for a fee, you must give the recipients all the rights that we gave you. You must make sure that they, too, receive or can get the source code. If you link a program with the library, you must provide complete object files to the recipients so that they can relink them with the library, after making changes to the library and recompiling it. And you must show them these terms so they know their rights. Our method of protecting your rights has two steps: (1) copyright the library, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the library. Also, for each distributor's protection, we want to make certain that everyone understands that there is no warranty for this free library. If the library is modified by someone else and passed on, we want its recipients to know that what they have is not the original version, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that companies distributing free software will individually obtain patent licenses, thus in effect transforming the program into proprietary software. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. Most GNU software, including some libraries, is covered by the ordinary GNU General Public License, which was designed for utility programs. This license, the GNU Library General Public License, applies to certain designated libraries. This license is quite different from the ordinary one; be sure to read it in full, and don't assume that anything in it is the same as in the ordinary license. The reason we have a separate public license for some libraries is that they blur the distinction we usually make between modifying or adding to a program and simply using it. Linking a program with a library, without changing the library, is in some sense simply using the library, and is analogous to running a utility program or application program. However, in a textual and legal sense, the linked executable is a combined work, a derivative of the original library, and the ordinary General Public License treats it as such. Because of this blurred distinction, using the ordinary General Public License for libraries did not effectively promote software sharing, because most developers did not use the libraries. We concluded that weaker conditions might promote sharing better. However, unrestricted linking of non-free programs would deprive the users of those programs of all benefit from the free status of the libraries themselves. This Library General Public License is intended to permit developers of non-free programs to use free libraries, while preserving your freedom as a user of such programs to change the free libraries that are incorporated in them. (We have not seen how to achieve this as regards changes in header files, but we have achieved it as regards changes in the actual functions of the Library.) The hope is that this will lead to faster development of free libraries. The precise terms and conditions for copying, distribution and modification follow. Pay close attention to the difference between a "work based on the library" and a "work that uses the library". The former contains code derived from the library, while the latter only works together with the library. Note that it is possible for a library to be covered by the ordinary General Public License rather than by this special one. GNU LIBRARY GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License Agreement applies to any software library which contains a notice placed by the copyright holder or other authorized party saying it may be distributed under the terms of this Library General Public License (also called "this License"). Each licensee is addressed as "you". A "library" means a collection of software functions and/or data prepared so as to be conveniently linked with application programs (which use some of those functions and data) to form executables. The "Library", below, refers to any such software library or work which has been distributed under these terms. A "work based on the Library" means either the Library or any derivative work under copyright law: that is to say, a work containing the Library or a portion of it, either verbatim or with modifications and/or translated straightforwardly into another language. (Hereinafter, translation is included without limitation in the term "modification".) "Source code" for a work means the preferred form of the work for making modifications to it. For a library, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the library. Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running a program using the Library is not restricted, and output from such a program is covered only if its contents constitute a work based on the Library (independent of the use of the Library in a tool for writing it). Whether that is true depends on what the Library does and what the program that uses the Library does. 1. You may copy and distribute verbatim copies of the Library's complete source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and distribute a copy of this License along with the Library. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Library or any portion of it, thus forming a work based on the Library, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) The modified work must itself be a software library. b) You must cause the files modified to carry prominent notices stating that you changed the files and the date of any change. c) You must cause the whole of the work to be licensed at no charge to all third parties under the terms of this License. d) If a facility in the modified Library refers to a function or a table of data to be supplied by an application program that uses the facility, other than as an argument passed when the facility is invoked, then you must make a good faith effort to ensure that, in the event an application does not supply such function or table, the facility still operates, and performs whatever part of its purpose remains meaningful. (For example, a function in a library to compute square roots has a purpose that is entirely well-defined independent of the application. Therefore, Subsection 2d requires that any application-supplied function or table used by this function must be optional: if the application does not supply it, the square root function must still compute square roots.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Library, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Library, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Library. In addition, mere aggregation of another work not based on the Library with the Library (or with a work based on the Library) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may opt to apply the terms of the ordinary GNU General Public License instead of this License to a given copy of the Library. To do this, you must alter all the notices that refer to this License, so that they refer to the ordinary GNU General Public License, version 2, instead of to this License. (If a newer version than version 2 of the ordinary GNU General Public License has appeared, then you can specify that version instead if you wish.) Do not make any other change in these notices. Once this change is made in a given copy, it is irreversible for that copy, so the ordinary GNU General Public License applies to all subsequent copies and derivative works made from that copy. This option is useful when you wish to copy part of the code of the Library into a program that is not a library. 4. You may copy and distribute the Library (or a portion or derivative of it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange. If distribution of object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place satisfies the requirement to distribute the source code, even though third parties are not compelled to copy the source along with the object code. 5. A program that contains no derivative of any portion of the Library, but is designed to work with the Library by being compiled or linked with it, is called a "work that uses the Library". Such a work, in isolation, is not a derivative work of the Library, and therefore falls outside the scope of this License. However, linking a "work that uses the Library" with the Library creates an executable that is a derivative of the Library (because it contains portions of the Library), rather than a "work that uses the library". The executable is therefore covered by this License. Section 6 states terms for distribution of such executables. When a "work that uses the Library" uses material from a header file that is part of the Library, the object code for the work may be a derivative work of the Library even though the source code is not. Whether this is true is especially significant if the work can be linked without the Library, or if the work is itself a library. The threshold for this to be true is not precisely defined by law. If such an object file uses only numerical parameters, data structure layouts and accessors, and small macros and small inline functions (ten lines or less in length), then the use of the object file is unrestricted, regardless of whether it is legally a derivative work. (Executables containing this object code plus portions of the Library will still fall under Section 6.) Otherwise, if the work is a derivative of the Library, you may distribute the object code for the work under the terms of Section 6. Any executables containing that work also fall under Section 6, whether or not they are linked directly with the Library itself. 6. As an exception to the Sections above, you may also compile or link a "work that uses the Library" with the Library to produce a work containing portions of the Library, and distribute that work under terms of your choice, provided that the terms permit modification of the work for the customer's own use and reverse engineering for debugging such modifications. You must give prominent notice with each copy of the work that the Library is used in it and that the Library and its use are covered by this License. You must supply a copy of this License. If the work during execution displays copyright notices, you must include the copyright notice for the Library among them, as well as a reference directing the user to the copy of this License. Also, you must do one of these things: a) Accompany the work with the complete corresponding machine-readable source code for the Library including whatever changes were used in the work (which must be distributed under Sections 1 and 2 above); and, if the work is an executable linked with the Library, with the complete machine-readable "work that uses the Library", as object code and/or source code, so that the user can modify the Library and then relink to produce a modified executable containing the modified Library. (It is understood that the user who changes the contents of definitions files in the Library will not necessarily be able to recompile the application to use the modified definitions.) b) Accompany the work with a written offer, valid for at least three years, to give the same user the materials specified in Subsection 6a, above, for a charge no more than the cost of performing this distribution. c) If distribution of the work is made by offering access to copy from a designated place, offer equivalent access to copy the above specified materials from the same place. d) Verify that the user has already received a copy of these materials or that you have already sent this user a copy. For an executable, the required form of the "work that uses the Library" must include any data and utility programs needed for reproducing the executable from it. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. It may happen that this requirement contradicts the license restrictions of other proprietary libraries that do not normally accompany the operating system. Such a contradiction means you cannot use both them and the Library together in an executable that you distribute. 7. You may place library facilities that are a work based on the Library side-by-side in a single library together with other library facilities not covered by this License, and distribute such a combined library, provided that the separate distribution of the work based on the Library and of the other library facilities is otherwise permitted, and provided that you do these two things: a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities. This must be distributed under the terms of the Sections above. b) Give prominent notice with the combined library of the fact that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work. 8. You may not copy, modify, sublicense, link with, or distribute the Library except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense, link with, or distribute the Library is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 9. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Library or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Library (or any work based on the Library), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Library or works based on it. 10. Each time you redistribute the Library (or any work based on the Library), the recipient automatically receives a license from the original licensor to copy, distribute, link with or modify the Library subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 11. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Library at all. For example, if a patent license would not permit royalty-free redistribution of the Library by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Library. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply, and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 12. If the distribution and/or use of the Library is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Library under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 13. The Free Software Foundation may publish revised and/or new versions of the Library General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Library specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Library does not specify a license version number, you may choose any version ever published by the Free Software Foundation. 14. If you wish to incorporate parts of the Library into other free programs whose distribution conditions are incompatible with these, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS Appendix: How to Apply These Terms to Your New Libraries If you develop a new library, and you want it to be of the greatest possible use to the public, we recommend making it free software that everyone can redistribute and change. You can do so by permitting redistribution under these terms (or, alternatively, under the terms of the ordinary General Public License). To apply these terms, attach the following notices to the library. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) This library is free software; you can redistribute it and/or modify it under the terms of the GNU Library General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. This library is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU Library General Public License for more details. You should have received a copy of the GNU Library General Public License along with this library; if not, write to the Free Software Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA. Also add information on how to contact you by electronic and paper mail. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the library, if necessary.

This mode of operation is selected by either setting the environment variable POSIXLY_CORRECT, or using `+' as the first character of the list of option characters. PERMUTE is the default. We permute the contents of ARGV as we scan, so that eventually all the non-options are at the end. This allows options to be given in any order, even with programs that were not written to expect this.

If an element of ARGV starts with '-', and is not exactly "-" or "--", then it is an option element. The characters of this element (aside from the initial '-') are option characters. If `getopt' is called repeatedly, it returns successively each of the option characters from each of the option elements. If `getopt' finds another option character, it returns that character, updating `optind' and `nextchar' so that the next call to `getopt' can resume the scan with the following option character or ARGV-element. If there are no more option characters, `getopt' returns -1. Then `optind' is the index in ARGV of the first ARGV-element that is not an option. (The ARGV-elements have been permuted so that those that are not options now come last.) OPTSTRING is a string containing the legitimate option characters. If an option character is seen that is not listed in OPTSTRING, return '?' after printing an error message. If you set `opterr' to zero, the error message is suppressed but we still return '?'. If a char in OPTSTRING is followed by a colon, that means it wants an arg, so the following text in the same ARGV-element, or the text of the following ARGV-element, is returned in `optarg'. Two colons mean an option that wants an optional arg; if there is text in the current ARGV-element, it is returned in `optarg', otherwise `optarg' is set to zero. If OPTSTRING starts with `-' or `+', it requests different methods of handling the non-option ARGV-elements. See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above. Long-named options begin with `--' instead of `-'. Their names may be abbreviated as long as the abbreviation is unique or is an exact match for some defined option. If they have an argument, it follows the option name in the same ARGV-element, separated from the option name by a `=', or else the in next ARGV-element. When `getopt' finds a long-named option, it returns 0 if that option's `flag' field is nonzero, the value of the option's `val' field if the `flag' field is zero. The elements of ARGV aren't really const, because we permute them. But we pretend they're const in the prototype to be compatible with other systems. LONGOPTS is a vector of `struct option' terminated by an element containing a name which is zero. LONGIND returns the index in LONGOPT of the long-named option found. It is only valid when a long-named option has been found by the most recent call. If LONG_ONLY is nonzero, '-' as well as '--' can introduce long-named options. */ int _getopt_internal (argc, argv, optstring, longopts, longind, long_only) int argc; char *const *argv; const char *optstring; const struct option *longopts; int *longind; int long_only; { int print_errors = opterr; if (optstring[0] == ':') print_errors = 0; optarg = NULL; if (optind == 0 || !__getopt_initialized) { if (optind == 0) optind = 1; /* Don't scan ARGV[0], the program name. */ optstring = _getopt_initialize (argc, argv, optstring); __getopt_initialized = 1; } /* Test whether ARGV[optind] points to a non-option argument.

Unread input are organised in a stack, implemented with an obstack. Each input source is described by a "struct input_block". The obstack is "input_stack". The top of the input stack is "isp". Each input_block has an associated struct input_funcs, that defines functions for peeking, reading, unget and cleanup. All input is done through the functions pointers of the input_funcs of the top most input_block. When a input_block is exhausted, its reader returns CHAR_RETRY which causes the input_block to be popped from the input_stack. Pushing new input on the input stack is done by push_file (), push_string (), push_single () or push_macro () (for macro definitions). Because macro expansion needs direct access to the current input obstack (for optimization), push_string () are split in two functions, push_string_init (), which returns a pointer to the current input stack, and push_string_finish (), which return a pointer to the final text. The input_block *next is used to manage the coordination between the different push routines. The current file and line number are stored in two global variables, for use by the error handling functions in mp4h.c. Whenever a file input_block is pushed, the current file name and line number is saved in the input_block, and the two variables are reset to match the new input file. THE SYNTAX TABLE The input is read character by character and grouped together according to a syntax table. The character groups are (definitions are all in mp4h.h: SYNTAX_IGNORE *Character to be deleted from input as if not present SYNTAX_OTHER Any character with no special meaning to mp4h SYNTAX_SPACE Whitespace (ignored when leading macro arguments) SYNTAX_ALPHA Alphabetic characters (can start macro names) SYNTAX_NUM Numeric characters SYNTAX_ALNUM Alphanumeric characters (can form macro names) Besides adding new facilities, the use of a syntax table will reduce the number of calls to next_token (). Now groups of OTHER, NUM and SPACE characters can be returned as a single token, since next_token () knows they have no special syntactical meaning to m4. This is, however, only possible if only single character quotes comments comments are used, because otherwise the quote and comment characters will not show up in the syntax-table. The precedence as implemented by next_token () is: SYNTAX_IGNORE *Filtered out below next_token () SYNTAX_ALPHA Reads macro name SYNTAX_OTHER and SYNTAX_NUM Reads all SYNTAX_OTHER and SYNTAX_NUM SYNTAX_SPACE Reads all SYNTAX_SPACE the rest Returned as a single char SYNTAX_DOLLAR is not currently used. The character $ is treated as a SYNTAX_OTHER. It could be done, but it will slow next_token () down a bit. The $ is not really a part of m4's input syntax in the sense that a string is parsed equally whether there is a $ or not. The character $ is used by convention in user macros. */ struct input_funcs { int (*peek_func)(void); /* function to peek input */ int (*read_func)(void); /* function to read input */ void (*unget_func)(int); /* function to unread input */ void (*clean_func)(void); /* function to clean up */ }; struct input_block { struct input_block *prev; /* previous input_block on the input stack */ struct input_funcs *funcs; /* functions on this input_block */ union { struct { unsigned int ch; /* single char value */ } u_c; struct { unsigned char *start; /* string value */ unsigned char *current; /* current value */ } u_s; struct { FILE *file; /* input file handle */ char *name; /* name of PREVIOUS input file */ int lineno; /* current line number for do */ /* Yet another attack of "The curse of global variables" (sigh) */ int out_lineno; /* current output line number do */ boolean advance_line; /* start_of_input_line from next_char () */ } u_f; struct { builtin_func *func; /* pointer to macros function */ boolean traced; /* TRUE iff builtin is traced */ boolean read; /* TRUE iff block has been read */ } u_m; } u; }; typedef struct input_block input_block; /* Current input file name. */ char *current_file; char **array_current_file; /* Current input line number. */ int current_line; int *array_current_line; /* Obstack for storing individual tokens. */ static struct obstack token_stack; /* Normal input stack. */ static struct obstack input_stack; /* Wrapup input stack. */ static struct obstack wrapup_stack; /* Input or wrapup. */ static struct obstack *current_input; /* Bottom of token_stack, for obstack_free. */ static char *token_bottom; /* Pointer to top of current_input. */ static input_block *isp; /* Pointer to top of wrapup stack. */ static input_block *wsp; /* Aux. for handling split push_string (). */ static input_block *next; /* Global */ static token_data token_read; /* Flag for next_char () to increment current_line. */ static boolean start_of_input_line; /* Input syntax table */ unsigned short syntax_table[256]; #define CHAR_EOF 256 /* character return on EOF */ #define CHAR_MACRO 257 /* character return for MACRO token */ #define CHAR_RETRY 258 /* character return for end of input block */ /* Comment chars. */ STRING eolcomm; STRING lquote, rquote; boolean visible_quotes; /*---------------------------------------------------------------------. | push_file () pushes an input file on the input stack, saving the | | current file name and line number.

A module is a * compiled shared object, that can be linked into GNU m4 at run * time. Information about creating modules is in ../modules/README. * * The current implementation uses either dlopen(3) (exists on * GNU/Linux, OSF, Solaris, SunOS) or shl_load(3) (exists on HPUX). To * enable this experimental feature give configure the `--with-modules' * switch. This implementation is only tested on GNU/Linux, OSF, * Solaris, SunOS and HPUX. * * A m4 module need only define one external symbol, called * `m4_macro_table'. This symbol should point to a table of `struct * builtin' exactly as the one in builtin.c. This table is pushed on a * list of builtin tables and each definition therein is added to the * symbol table. * * The code implementing loadable modules is modest. It is divided * between the files builtin.c (user interface and support for multiple * builtin tables) and this file (OS dependant routines). * * To load a module, use `loadmodule(modulename)'. The function * `m4_loadmodule' calls module_load() in this file, which uses * module_search() to find the module in the module search path. This * path is initialised from the environment variable MP4HMODPATH, or if * not set, initalised to a configuration time default. Module_search() * constructs absolute file names and calls module_try_load(). This * function reads the libtool .la file to get the real library name * (which can be system dependent) and returns NULL on failure and a * non-NULL void* on success. If succesful module_search() returns the * value of this void*, which is a handle for the vm segment mapped. * Module_load() checks to see if the module is alreay loaded, and if * not, retrives the symbol `m4_macro_table' and returns it's value to * m4_loadmodule(). This pointer should be a builtin*, which is * installed using install_builtin_table(). * * When a module is loaded, the function "void m4_init_module(struct * obstack *obs)" is called, if defined. Any non NULL return value of * this function will be the expansion of "loadmodule". Before program * exit, all modules are unloaded and the function "void * m4_finish_module(void)" is called, if defined. * * There is no way to unload a module unless at program exit.

The former inspired mp4h syntax whereas source code is derived from the latter. Mp4h syntax is immediately familiar to HTML programmers. Users can define their own tags, and programming constructs like loops, arrays, conditionals make mp4h very powerful. Mp4h is extendable to fit every needs. It can of course load new macro definitions put in package files, but also dynamically load shared libraries containing compiled macro definitions. -- Denis Barbier mp4h-1.3.1/doc/0000777000175000017500000000000007610122327006676 5mp4h-1.3.1/doc/Makefile.am0000664000175000017500000000246707545134404010667 PROGDIR = $(top_builddir)/src PROGRAM = $(PROGDIR)/mp4h FLAGS = -X 0 -I $(srcdir) -D srcdir="$(srcdir)" DEPS = list-tags TIDY = @TIDY@ man1_MANS = mp4h.1 SUFFIXES = .info .ps .dvi .texi .1 .pod .texi.info: makeinfo $< .texi.dvi: texi2dvi $< .dvi.ps: dvips -o $@ $< .pod.1: pod2man --section=1 \ --center="HTML Tools" \ --release="HTML Tools" \ $< > $@ all: $(PROGRAM) mp4h.1 mp4h.html mp4h.html: mp4h.mp4h html.out $(PROGRAM) $(DEPS) $(PROGRAM) $(FLAGS) -D format=html $(srcdir)/mp4h.mp4h > $@ -$(TIDY) $(TIDYOPT) -m $@ mp4h.pod: mp4h.mp4h pod.out $(PROGRAM) $(DEPS) $(PROGRAM) $(FLAGS) -D format=pod $(srcdir)/mp4h.mp4h \ | sed -e 's/_LT_//g' > $@ mp4h.texi: mp4h.mp4h texinfo.out $(PROGRAM) $(DEPS) $(PROGRAM) $(FLAGS) -D format=texinfo -D info:gentoc=1 $(srcdir)/mp4h.mp4h |\ grep '@remove@' | sed -e 's/@remove@//' -e 's/=LT=/ mp4h.chp $(PROGRAM) $(FLAGS) -D format=texinfo $(srcdir)/mp4h.mp4h > $@ $(PROGRAM): cd $(PROGDIR) && $(MAKE) EXTRA_DIST = mp4h.mp4h list-tags html.out pod.out texinfo.out CLEANFILES = \ mp4h.pod mp4h.1 \ mp4h.html \ mp4h.info mp4h.info-* mp4h.texi mp4h.chp mp4h.cp mp4h.fn mp4h.vr \ mp4h.tp mp4h.ky mp4h.pg mp4h.aux mp4h.log mp4h.toc mp4h.dvi mp4h.ps mp4h-1.3.1/doc/Makefile.in0000664000175000017500000002264407610120045010664 # Makefile.in generated by automake 1.6.3 from Makefile.am. # @configure_input@ # Copyright 1994, 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002 # Free Software Foundation, Inc. # This Makefile.in is free software; the Free Software Foundation # gives unlimited permission to copy and/or distribute it, # with or without modifications, as long as this notice is preserved. # This program is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY, to the extent permitted by law; without # even the implied warranty of MERCHANTABILITY or FITNESS FOR A # PARTICULAR PURPOSE. @SET_MAKE@ SHELL = @SHELL@ srcdir = @srcdir@ top_srcdir = @top_srcdir@ VPATH = @srcdir@ prefix = @prefix@ exec_prefix = @exec_prefix@ bindir = @bindir@ sbindir = @sbindir@ libexecdir = @libexecdir@ datadir = @datadir@ sysconfdir = @sysconfdir@ sharedstatedir = @sharedstatedir@ localstatedir = @localstatedir@ libdir = @libdir@ infodir = @infodir@ mandir = @mandir@ includedir = @includedir@ oldincludedir = /usr/include pkgdatadir = $(datadir)/@PACKAGE@ pkglibdir = $(libdir)/@PACKAGE@ pkgincludedir = $(includedir)/@PACKAGE@ top_builddir = ..

Introduction
The &mp4h; software is a macro-processor specifically designed to deal with HTML documents. It allows powerful programming constructs, with a syntax familiar to HTML authors. This software is based on , written by Brian J. Fox, Even if both syntaxes look similar, source code is completely different. Indeed, a subset of &Meta-HTML; was used as a part of a more complex program, &WML; () written by Ralf S. Engelschall and which I maintain since January 1999. For licensing reasons, it was hard to hack &Meta-HTML; and so I decided to write my own macro-processor. Instead of rewriting it from scratch, I preferred using another macro-processor engine. I chose , written by René Seindal, because of its numerous advantages : this software is stable, robust and very well documented. This version of &mp4h; is derived from GNU &m4; version 1.4n, which is a development version. The &mp4h; software is not an HTML editor; its unique goal is to provide an easy way to define its own macros inside HTML documents. There is no plan to add functionalities to automagically produce valid HTML documents, if you want to clean up your code or validate it, simply use a post-processor like .
Command line options
Optional arguments are enclosed within square brackets. All option synonyms have a similar syntax, so when a long option accepts an argument, short option do too. Syntax call is mp4h [options] [filename [filename] ...] Options are described below. If no filename is specified, or if its name is , then characters are read on standard input. Operation modes Preprocessor features Parser features NUMBER is a combination of In version <__version__ />, default value is 3114=2+8+32+1024+2048. Limits control Debugging Flags are any of:
Description
The &mp4h; software is a macro-processor, which means that keywords are replaced by other text. This chapter describes all primitives. As &mp4h; has been specially designed for HTML documents, its syntax is very similar to HTML, with tags and attributes. One important feature has no equivalent in HTML: comments until end of line. All text following three colons is discarded until end of line, like ;;; This is a comment ### ### Defining new macros ### Function Macros All examples in this documentation are processed through &mp4h; with expansion flags set to zero (see a description of possible expansion flags at the end of document), it is why simple tags contain a trailing slash. But &mp4h; can output plain HTML files with other expansion flags. The definition of new tags is the most common task provided by &mp4h;. As with HTML, macro names are case insensitive, unless option is used to change this default behaviour. In this documentation, only lowercase letters are used. There are two kinds of tags: simple and complex. A simple tag has the following form: whereas a complex tag looks like: body Since version 0.9.1, &mp4h; knows XHTML syntax too, so your input file may conform to HTML or XHTML syntax. In this manual, we adopt the latter, which is why simple tags have a trailing slash in attributes. If you want to produce HTML files with this input file, you may either choose an adequate flag or use a post-processor like . When a simple tag is defined by &mp4h;, it can be parsed even if the trailing slash is omitted, because &mp4h; knows that this tag is simple. But it is a good practice to always append a trailing slash to simple tags. In macro descriptions below, a slash indicates a simple tag, and a V letter that attributes are read verbatim (without expansion) (see the chapter on macro expansion for further details). [attributes=verbatim] [endtag=required] [whitespace=delete] This function lets you define your own tags. First argument is the command name. Replacement text is the function body. bar Even if spaces have usually few incidence on HTML syntax, it is important to note that bar and bar are not equivalent, the latter form contains two newlines that were not present in the former. Some spaces are suppressed in replacement text, in particular any leading or trailing spaces, and newlines not enclosed within angle brackets. Define a complex tag bar ;;; body is: %body Here it is By default attributes are expanded before text is replaced. If this attribute is used, attributes are inserted into replacement text without expansion. quux Body: %Ubody Attributes: %Uattributes Here we go [attributes=verbatim] [endtag=required] [whitespace=delete] This command is similar to the previous one, except that no operation is performed if this command was already defined. = Copy a function. This command is useful to save a macro definition before redefining it. one two Delete a command definition. one [position=before|after] [action=insert|append|replace] Add text to a predefined macro. This mechanism allows modifications of existing macros without having to worry about its type, whether it is complex or not. Before After [position=before|after] Print current hooks of a macro. Text inserted with position=before:! Text inserted with position=after:! Like , except that pairs are printed with double quotes surrounding attribute values, and a leading space is added if some text is printed. ;;; %attributes /> [,[,...]] Extract from the pairs for names matching any of , .... /> [,[,...]] Remove from the pairs for names matching any of , .... />/> The two previous functions are special, because unlike all other macros, their expansion do not form a group. This is necessary to parse the resulting list of attributes. In those two functions, names of attributes may be regular expressions. Main goal of these primitives is to help writing macros accepting any kind of attributes without having to declare them. A canonical example is /> /> href=""> But we want now to add an image attribute. So we may write /> /> href=""> /> src="" alt="" border=0 /> /> We need a mechanism to tell &mp4h; that some attributes refer to specific HTML tags. A solution is to prepend attribute with tag name, e.g. /> /> href=""> /> src="" alt="" /> /> This example shows that regular expressions may be used within attributes names, but it is still incomplete, because we want to remove prefix from attributes. One solution is with , but there is a more elegant one: /> /> href=""> /> src="" alt="" /> /> When there are subexpressions within regular expressions, they are printed instead of the whole expression. Note also that I put a colon before the prefix in order not to mix them with XML namespaces. ### ### Entity functions ### Entities Entities are macros in the same way as tags, but they do not take any arguments. Whereas tags are normally used to mark up text, entities contain already marked up text. Also note that unlike tags, entities are by default case sensitive. An entity has the following form: &entity; This function lets you define your own entities. First argument is the entity name. Replacement text is the function body. bar &foo; ### ### Variable functions ### Variables Variables are a special case of simple tags, because they do not accept attributes. In fact their use is different, because variables contain text whereas macros act like operators. A nice feature concerning variables is their manipulation as arrays. Indeed variables can be considered like newline separated lists, which will allow powerful manipulation functions as we will see below. [=] [[=]] ... This command sets variables. [=] [[=]] ... As above but attributes are read verbatim. name= This command assigns a variable the value of the body of the command. This is particularly useful when variable values contain newlines and/or quotes. Note that the variable can not be indexed with this command. Note also, that this command behaves as set-var-verbatim: The body is not expanded until the variable is shown with get-var. [] ... Show variable contents. If a numeric value within square brackets is appended to a variable name, it represents the index of an array. The first index of arrays is 0 by convention. This is version Operating sytem is "" [] ... As above but attributes are not expanded. 0.10.1 ;;; Here is version ;;; Here is version ;;; Here is version [] ... All variables are global, there is no variable or macro scope. For this reason a stack is used to preserve variables. When this command is invoked, arguments are names of variables, whose values are put at the top of the stack and variables are reset to an empty string. [] ... This is the opposite: arguments are names of variables, which are set to the value found at the top of the stack, and stack is popped down. The tag pushes its last argument first, whereas first pops its first argument. Inside: src= name= text= Before: src= name= text= After: src= name= text= [] ... Undefine variables. Returns when this variable exists. [by=] Increment the variable whose name is the first argument. Default increment is one. "> Change increment amount. [by=] Decrement the variable whose name is the first argument. Default decrement is one. "> Change decrement amount. Copy a variable into another. If this variable is not defined or is defined to an empty string, then it is set to the second argument. Show informations on symbols. If it is a variable name, the word is printed as well as the number of lines contained within this variable. If it is a macro name, one of the following messages is printed: , , or bar quux ### ### String functions ### String Functions Prints the length of the string. ;;; /> ;;; /> />;;; Convert to lowercase letters. Convert to uppercase letters. Convert to a title, with a capital letter at the beginning of every word. [ []] Extracts a substring from a string. First argument is original string, second and third are respectively start and end indexes. By convention first character has a null index. 4 /> 4 6 /> [caseless=true] Returns if first two arguments are equal. 1: 2: Comparison is case insensitive. 1: 2: [caseless=true] Returns if the first two arguments are not equal. 1: 2: Comparison is case insensitive. 1: 2: [caseless=true] Compares two strings and returns one of the values less, greater or equal depending on this comparison. 1: 2: Comparison is case insensitive. 1: [caseless=true] Prints an array containing indexes where the character appear in the string. Comparison is case insensitive. 1: 2: [ ...] Prints according to a given format. Currently only the flag character is recognized, and extension is supported to change order of arguments. 1: 2: ### ### Regexp functions ### Regular Expressions Regular expression support is provided by the PCRE (Perl Compatible Regular Expressions) library package, which is open source software, copyright by the University of Cambridge. This is a very nice piece of software, latest versions are available at . Before version 1.0.6, POSIX regular expressions were implemented. For this reason, the following macros recognize two attributes, and . But Perl allows a much better control on regular expressions with so called modifiers, which are assed to the new attribute. It may contain one or more modifiers: Attribute is a synonym for the modifier, whereas is a synonym for the modifier. This behaviour was different up to &mp4h; 1.0.6. [] [caseless=true] [singleline=true|false] [reflags=[imsx]] Replace a regular expression in a string by a replacement text. "[c-e]" /> "([c-e])" "\\1 " /> ".$" "" /> ".$" "" singleline=false /> " ([a-c]) | [0-9] " ":\\1:" reflags=x /> [] [caseless=true] [singleline=true|false] [reflags=[imsx]] Performs substitutions inside variable content. [caseless=true] [singleline=true|false] [reflags=[imsx]] [action=report|extract|delete|startpos|endpos|length] Prints if string contains regexp. Prints the expression matching regexp in string. Prints the string without the expression matching regexp in string. Prints the first char of the expression matching regexp in string. If there is no match, returns . Prints the last char of the expression matching regexp in string. If there is no match, returns . Prints the length of the expression matching regexp in string. 1: 2: 3: 4: 5: 6: ### ### Array functions ### Arrays With &mp4h; one can easily deal with string arrays. Variables can be treated as a single value or as a newline separated list of strings. Thus after defining one can view its content or one of these values: Returns an array size which is the number of lines present in the variable. Add a value (or more if this value contains newlines) at the end of an array. Remove the toplevel value of an array and returns this string. Prints the last entry of an array. [caseless=true] Add a value at the end of an array if this value is not already present in this variable. Comparison is case insensitive. [] ... Concatenates all arrays into the first one. [caseless=true] If value is contained in array, returns its index otherwise returns -1. Comparison is case insensitive. [start=] Shifts an array. If offset is negative, indexes below 0 are lost. If offset is positive, first indexes are filled with empty strings. Now: And: "> Change origin of shifts (default is 0). [caseless=true] [numeric=true] [sortorder=reverse] Sort lines of an array in place. Default is to sort lines alphabetically. Comparison is case insensitive. Sort lines numerically Reverse sort order ;;; ### ### Numerical operators ### Numerical operators These operators perform basic arithmetic operations. When all operands are integers result is an integer too, otherwise it is a float. These operators are self-explanatory. [] ... [] ... [] ... [] ... [] ... [] ... />" /> /> Unlike functions listed above the modulo function cannot handle more than 2 arguments, and these arguments must be integers. Those functions compare two numbers and returns when this comparison is true. If one argument is not a number, comparison is false. Returns if first argument is greater than second. Returns if first argument is lower than second. Returns if arguments are equal. Returns if arguments are not equal. ### ### Relational operators ### Relational operators Returns if string is empty, otherwise returns an empty string. [] ... Returns the last argument if all arguments are non empty. [] ... Returns the first non empty argument. ### ### Flow functions ### Flow functions [] ... [separator=] This function groups multiple statements into a single one. Some examples will be seen below with conditional operations. A less intuitive but very helpful use of this macro is to preserve newlines when is specified. Text on 3 lines without whitespace=delete Text on 3 lines with whitespace=delete Note that newlines are suppressed in and result is certainly unwanted. [] ... [separator=] Like , but this tag is complex. "> By default arguments are put aside. This attribute define a separator inserted between arguments. Does the opposite job to , its argument is no more treated as a single object when processed by another command. [] ... Prints its arguments without expansion. They will never be expanded unless the tag is used to cancel this tag. [] ... Cancels the tag. bar=LT=/define-tag>" "=LT=" "<" /> quux=LT=/define-tag>" "=LT=" "" /> [] If string is non empty, second argument is evaluated otherwise third argument is evaluated. [] If first two arguments are identical strings, third argument is evaluated otherwise fourth argument is evaluated. [] If first two arguments are not identical strings, third argument is evaluated otherwise fourth argument is evaluated. When argument is not empty, its body is evaluated. While condition is true, body function is evaluated. 0 />>;;; ;;; [start=] [end=] [step=] This macro is similar to the Perl's macro: a variable loops over array values and function body is evaluated for each value. first argument is a generic variable name, and second is the name of an array. "> Skips first indexes. "> Stops after index has reached that value. "> Change index increment (default is 1). If step is negative, array is treated in reverse order. = [= ... This command performs multiple conditions with a single instruction. x /> x=2 x /> y=1 y /> y=2 y /> /> Breaks the innermost loop. 0 />>;;; ;;; 5 />;;; [up=number] This command immediately exits from the innermost macro. A message may also be inserted. But this macro changes token parsing so its use may become very hazardous in some situations. "> This attribute determines how much levels have to be exited. By default only one level is skipped. With a null value, all current macros are exited from. A negative value do the same, and stops processing current file. Prints a warning on standard error. [status=] [message=] Immediately exits program. "> Prints a message to the standard error. "> Selects the code returned by the program (-1 by default). This is a special command: its content is stored and will be expanded after end of input. ### ### File functions ### File functions [matching=regexp] Returns a newline separated list of files contained in a given directory. patname= Resolves all symbolic links, extra ``/'' characters and references to /./ and /../ in pathname, and expands into the resulting absolute pathname. All but the last component of pathname must exist when real-path is called. This tag is particularly useful when comparing if file or directory names are identical. /> Returns if file exists. Returns an array of informations on this file. These informations are: size, type, ctime, mtime, atime, owner and group. /> file= | command= [alt=] [verbatim=true] Insert the contents of a file in the file system - if the attribute is given -, or the output from executing a system command - if the attribute is given - into the input stream. For backwards compatibility, if neither the nor the attributes are given, the first argument is taken as a file to include. "> The given file is read and inserted into the input stream. This attribute cannot be combined with the command attribute. Files are first searched in current directory, then in directories specified on command-line with the option, next in directories listed in the MP4HLIB environment variable (it used to be MP4HPATH for versions prior to 1.3), and last under the compile-time location (/usr/local/lib/mp4h/<__version__ />:/usr/local/share/mp4h by default). "> The given command line is executed on the operating system, and the output of it is inserted in the input stream. This attribute cannot be combined with the file attribute. The given command line is executed using the popen(3) standard C library routine. The command is executed using the standard system shell, which on Posix compliant systems is sh(1). "> If file is not found, this alternate action is handled. If this atribute is not set and file is not found, then an error is raised. This attribute has no effect when the command attribute is specified. File content is included without expansion. This is similar to using the &m4; undivert macro with a filename as argument. name= Load definitions from a package file. This tag does nothing, its body is simply discarded. [] Change comment characters. [ ] [display=visible] By default, all characters between and pairs are read without parsing. When called without argument, this macro inhibates this feature. When called with two arguments, it redefines begin and end delimiters. Begin delimiter must begin with a left-angle bracket, and end delimiter must end with a right-angle bracket. Delimiters are also written into output. ### ### Diversion functions ### Diversion functions Diversions are a way of temporarily saving output. The output of &mp4h; can at any time be diverted to a temporary file, and be reinserted into the output stream, undiverted, again at a later time. Numbered diversions are counted from 0 upwards, diversion number 0 being the normal output stream. The number of simultaneous diversions is limited mainly by the memory used to describe them, because &mp4h; tries to keep diversions in memory. However, there is a limit to the overall memory usable by all diversions taken altogether. When this maximum is about to be exceeded, a temporary file is opened to receive the contents of the biggest diversion still in memory, freeing this memory for other diversions. So, it is theoretically possible that the number of diversions be limited by the number of available file descriptors. [ divnum= ] Output is diverted using this tag, where diversion-number is the diversion to be used. If the divnum attribute is left out, diversion-number is assumed to be zero. If output is diverted to a non-existent diversion, it is simply discarded. This can be used to suppress unwanted output. See the example below. When all &mp4h; input will have been processed, all existing diversions are automatically undiverted, in numerical order. Several calls of divert with the same argument do not overwrite the previous diverted text, but append to it. This is sent nowhere... This is output. [ divnum= ] This tag explicitly undiverts diverted text saved in the diversion with the specified number. If the divnum attribute is not given, all diversions are undiverted, in numerical order. When diverted text is undiverted, it is not reread by &mp4h;, but rather copied directly to the current output. It is therefore not an error to undivert into a diversion. Unlike &m4;, the &mp4h; undivert tag does not allow a file name as argument. The same can be accomplished with the include tag with the verbatim="true" attribute. This text is diverted. This text is not diverted. This tag expands to the number of the current diversion. Initial Diversion one: Diversion two: ### ### Debugging ### Debugging functions When constructs become complex it could be hard to debug them. Functions listed below are very useful when you could not figure what is wrong. These functions are not perfect yet and must be improved in future releases. Prints the replacement text of a user defined macro. For instance, the macro used to generate all examples of this documentation is This comand acts like the flag but can be ynamically changed. Selects a file where debugging messages are diverted. If this filename is empty, debugging messages are sent back to standard error, and if it is set to these messages are discarded. There is no way to print these debugging messages into the document being processed. [] ... Declare these macros traced, i.e. informations about these macros will be printed if flag or macro are used. [] ... These macros are no more traced. ### ### Miscellaneous ### Miscellaneous [] Without argument this macro prints current input filename. With an argument, this macro sets the string returned by future invocation of this macro. [] Without argument this macro prints current number line in input file. With an argument, this macro sets the number returned by future invocation of this macro. This is <__file__/>, line <__line__/>. If you closely look at source code you will see that this number is wrong. Indeed the number line is the end of the entire block containing this instruction. Prints the version of &mp4h;. Discard all characters until newline is reached. This macro ensures that following string is a comment and does not depend of the value of comment characters. This is a comment foo This is a comment bar [epoch] Prints local time according to the epoch passed on argument. If there is no argument, current local time is printed. An epoch time specification. A format specification as used with the strftime(3) C library routine. /> /> /> Prints the time spent since last call to this macro. The printed value is the number of clock ticks, and so is dependant of your CPU. The number of clock ticks since the beginning of generation of this documentation by &mp4h; is: = Set locale-specific variables. By default, the portable "C" locale is selected. As locales have different names on different platforms, you must refer to your system documentation to find which values are adapted to your system. Change the output format of floats by setting the number of digits after the decimal point. Default is to print numbers in the "%6.f" format.
External packages
It is possible to include external files with the command. Files are first searched in current directory, then in directories specified on command-line with the option, next in directories listed in the MP4HLIB environment variable (it used to be MP4HPATH for versions prior to 1.3), and last under the compile-time location (/usr/local/lib/mp4h/<__version__ />:/usr/local/share/mp4h by default). Another way to include packages is with the command. There are two differences between and : first, package name has no suffix; and more important, a package cannot be loaded more than once.
Macro expansion
This part describes internal mechanism of macro expansion. It must be as precise and exhaustive as possible so if you have any suggestion. Basics Let us begin with some examples: This is a simple tag This is a complex tag Body function User defined macros may have attributes like HTML tags. To handle these attributes in replacement text, following conventions have been adopted (mostly derived from &Meta-HTML;): Sequence is replaced by the command name. Attributes are numbered from 0. In replacement text, is replaced by first argument, by the 2nd, etc. As there is no limitation on the number of arguments, is the 21st argument and not the third followed by the 0 letter. %1 Sequence prints number of attributes. Sequence is replaced by , which is useful in nested definitions. ;;; outer, # attributes: %# ;;; inner1, # attributes: %#;;; ;;; ;;; inner2, # attributes: %%#;;; ;;; Sequence is replaced by the space separated list of attributes. Sequence is replaced by the body of a complex macro. %body Dr. Foo The two forms above accept modifiers. When or is used, a newline separated list of attributes is printed. : " /> Another alternate form is obtained by replacing by , in which case text is replaced but will not be expanded. This does make sense only when macro has been defined with , otherwise attributes are expanded before replacement. Before expansion: %Uattributes After expansion: %attributes Before expansion: %Uattributes After expansion: %attributes and here %attributes /> /> Modifiers and can be combined. Input expansion is completely different in &Meta-HTML; and in &mp4h;. With &Meta-HTML; it is sometimes necessary to use other constructs like and . In order to improve compatibity with &Meta-HTML;, these constructs are recognized and are interpreted like . Another feature provided for compatibility reason is the fact that for simple tags and are equivalent. These features are in the current &mp4h; version but may disappear in future releases. Attributes Attributes are separated by spaces, tabulations or newlines, and each attribute must be a valid &mp4h; entity. For instance with the definitions above, can not be an attribute since it must be finished by . But this is valid: /> or even /> In these examples, the tag has only one argument. Under certain circumstances it is necessary to group multiple statements into a single one. This can be done with double quotes or with the primitive, e.g. /> Unlike HTML single quotes can not replace doube quotes for this purpose. If double quotes appear in an argument, they must be escaped by a backslash " />. Macro evaluation Macros are characterized by name container status (simple or complex) if attributes are expanded or not function type (primitive or user defined macro) for primitives, adress of corresponding code in memory and for user defined macros the replacement text Characters are read on input until a left angle bracket is found. Then macro name is read. After that attributes are read, verbatim or not depending on how this macro as been defined. And if this macro is complex, its body is read verbatim. When this is finished, some special sequences in replacement text are replaced (like , , , , etc.) and resulting text is put on input stack in order to be rescanned. By default attributes are evaluated before any replacement. %body Consider the following example, to change text in typewriter font: %body This definition has a major drawback: This is an example We would like the inner tags be removed. 1 "" /> %body 1 "" /> First idea is to use an auxiliary variable to know whether we still are inside such an environment: 1 "" /> %body 1 "" /> (the presence of asterisks in HTML tags is explained in next section). This is an example But if we use simple tags, as in the example below, our definition does not seem to work. It is because attributes are expanded before they are put into replacement text. %attributes " /> If we want to prevent this problem we have to forbid attributes expansion with ;;; %attributes;;; " /> Expansion flags When you want to embed some server-side scripting language in your pages, you face up some weird problems, like in >Hello The question is how do &mp4h; know that this input has some extra delimiters? The answer is that &mp4h; should not try to handle some special delimiters, because it cannot handle all of them (there are ASP, ePerl, PHP,... and some of them are customizable). Now, remember that &mp4h; is a macro-processor, not an XML parser. So we must focus on macros,and format our input file so that it can be parsed without any problem. Previous example may be written Hello because quotes prevent inner right-angle bracket from closing the tag. Another common problem is when we need to print only a begin or an end tag alone. For instance it is very desirable to define its own headers and footers with ... put here some informations .... Asterisks mark these tags as pseudo-simple tags, which means that they are complex HTML tags, but used as simple tags within &mp4h; because tags would not be well nested otherwise. This asterisk is called ``trailing star'', it appears at the end of the tag name. Sometimes HTML tags are not parsable, as in this javascript code: ... document.write('<*img src="foo.gif"'); if (text) document.write(' alt="'+text+'"'); document.write('>'); ... The ``leading star'' is an asterisk between left-angle bracket and tag name, which prevents this tag from being parsed. That said we can now understand what the flag is for. It controls how expansion is performed by mp4h. It is followed by an integer, which is a bit sum of the following values Run mp4h -h to find default value. Current value matches HTML syntax, and it will tend to zero when XHTML syntax becomes more familiar.
