We avoid this by adding ## dummy dependencies for each header file. Too bad gcc doesn't do ## this for us directly. ## Some versions of gcc put a space before the ':'. On the theory ## that the space means something, we add a space to the output as ## well. hp depmode also adds that space, but also prefixes the VPATH ## to the object.

How is it so fast? * Searching for literals (no regex) uses Boyer-Moore-Horspool strstr. * Files are mmap()ed instead of read into a buffer. * If you're building with PCRE 8.21 or greater, regex searches use the JIT compiler. * Ag calls pcre_study() before executing the regex on a jillion files. * Instead of calling fnmatch() on every pattern in your ignore files, non-regex patterns are loaded into an array and binary searched. * Ag uses Pthreads to take advantage of multiple CPU cores and search files in parallel. %prep %setup -q %build aclocal autoconf autoheader automake --add-missing %configure make %{?_smp_mflags} %install rm -rf ${RPM_BUILD_ROOT} make install DESTDIR=${RPM_BUILD_ROOT} mkdir -p ${RPM_BUILD_ROOT}%{_bashcompdir} install -m 644 ag.bashcomp.sh ${RPM_BUILD_ROOT}%{_bashcompdir} %clean rm -rf ${RPM_BUILD_ROOT} %files %defattr(-,root,root,-) %{_bindir}/* %{_mandir}/* %config %{_bashcompdir}/ag.bashcomp.sh %config %{_datadir}/%{name}/completions/ag.bashcomp.sh %changelog * Thu Dec 5 2013 Emily Strickland - 0.18.1-1 - More accurate build and install requirements * Fri Aug 16 2013 Andrew Seidl - 0.15.0-1 - Install bash completion file * Wed Dec 05 2012 Daniel Nelson - 0.13.1-1 - Initial Build the_silver_searcher-2.2.0/configure.ac0000644000175000017500000000526413332237264014756 00000000000000AC_INIT( [the_silver_searcher], [2.2.0], [https://github.com/ggreer/the_silver_searcher/issues], [the_silver_searcher], [https://github.com/ggreer/the_silver_searcher]) AM_INIT_AUTOMAKE([no-define foreign subdir-objects]) AC_PROG_CC AM_PROG_CC_C_O AC_PREREQ([2.59]) AC_PROG_GREP m4_ifdef( [AM_SILENT_RULES], [AM_SILENT_RULES([yes])]) PKG_CHECK_MODULES([PCRE], [libpcre]) m4_include([m4/ax_pthread.m4]) AX_PTHREAD( [AC_CHECK_HEADERS([pthread.h])], [AC_MSG_WARN([No pthread support.

In an in-source build this is usually # harmless because $srcdir is '.', but things will broke when you # start a VPATH build or use an absolute $srcdir. # # So we could use something similar to $top_srcdir/$ac_aux_dir/missing, # iff we strip the leading $srcdir from $ac_aux_dir.

Why use Ag? * It searches code about 3–5× faster than ack. * It ignores file patterns from your .gitignore and .hgignore. * If there are files in your source repo you don't want to search, just add their patterns to a .ignore file. *cough* extern *cough* * The command name is 33% shorter than ack! How is it so fast? * Searching for literals (no regex) uses Boyer-Moore-Horspool strstr. * Files are mmap()ed instead of read into a buffer. * If you're building with PCRE 8.21 or greater, regex searches use the JIT compiler. * Ag calls pcre_study() before executing the regex on a jillion files. * Instead of calling fnmatch() on every pattern in your ignore files, non-regex patterns are loaded into an array and binary searched. * Ag uses Pthreads to take advantage of multiple CPU cores and search files in parallel. %prep %setup -q %build aclocal autoconf autoheader automake --add-missing %configure make %{?_smp_mflags} %install rm -rf ${RPM_BUILD_ROOT} make install DESTDIR=${RPM_BUILD_ROOT} mkdir -p ${RPM_BUILD_ROOT}%{_bashcompdir} install -m 644 ag.bashcomp.sh ${RPM_BUILD_ROOT}%{_bashcompdir} %clean rm -rf ${RPM_BUILD_ROOT} %files %defattr(-,root,root,-) %{_bindir}/* %{_mandir}/* %config %{_bashcompdir}/ag.bashcomp.sh %config %{_datadir}/%{name}/completions/ag.bashcomp.sh %changelog * Thu Dec 5 2013 Emily Strickland - 0.18.1-1 - More accurate build and install requirements * Fri Aug 16 2013 Andrew Seidl - 0.15.0-1 - Install bash completion file * Wed Dec 05 2012 Daniel Nelson - 0.13.1-1 - Initial Build the_silver_searcher-2.2.0/m4/0000755000175000017500000000000013332240042013045 500000000000000the_silver_searcher-2.2.0/m4/ax_pthread.m40000664000175000017500000003267613035360703015375 00000000000000# =========================================================================== # http://www.gnu.org/software/autoconf-archive/ax_pthread.html # =========================================================================== # # SYNOPSIS # # AX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]]) # # DESCRIPTION # # This macro figures out how to build C programs using POSIX threads. It # sets the PTHREAD_LIBS output variable to the threads library and linker # flags, and the PTHREAD_CFLAGS output variable to any special C compiler # flags that are needed. (The user can also force certain compiler # flags/libs to be tested by setting these environment variables.) # # Also sets PTHREAD_CC to any special C compiler that is needed for # multi-threaded programs (defaults to the value of CC otherwise). (This # is necessary on AIX to use the special cc_r compiler alias.) # # NOTE: You are assumed to not only compile your program with these flags, # but also link it with them as well. e.g. you should link with # $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS # # If you are only building threads programs, you may wish to use these # variables in your default LIBS, CFLAGS, and CC: # # LIBS="$PTHREAD_LIBS $LIBS" # CFLAGS="$CFLAGS $PTHREAD_CFLAGS" # CC="$PTHREAD_CC" # # In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant # has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to that name # (e.g. PTHREAD_CREATE_UNDETACHED on AIX). # # Also HAVE_PTHREAD_PRIO_INHERIT is defined if pthread is found and the # PTHREAD_PRIO_INHERIT symbol is defined when compiling with # PTHREAD_CFLAGS. # # ACTION-IF-FOUND is a list of shell commands to run if a threads library # is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it # is not found. If ACTION-IF-FOUND is not specified, the default action # will define HAVE_PTHREAD. # # Please let the authors know if this macro fails on any platform, or if # you have any other suggestions or comments. This macro was based on work # by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help # from M. Frigo), as well as ac_pthread and hb_pthread macros posted by # Alejandro Forero Cuervo to the autoconf macro repository. We are also # grateful for the helpful feedback of numerous users. # # Updated for Autoconf 2.68 by Daniel Richard G. # # LICENSE # # Copyright (c) 2008 Steven G.

It # sets the PTHREAD_LIBS output variable to the threads library and linker # flags, and the PTHREAD_CFLAGS output variable to any special C compiler # flags that are needed. (The user can also force certain compiler # flags/libs to be tested by setting these environment variables.) # # Also sets PTHREAD_CC to any special C compiler that is needed for # multi-threaded programs (defaults to the value of CC otherwise). (This # is necessary on AIX to use the special cc_r compiler alias.) # # NOTE: You are assumed to not only compile your program with these flags, # but also link it with them as well. e.g. you should link with # $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS # # If you are only building threads programs, you may wish to use these # variables in your default LIBS, CFLAGS, and CC: # # LIBS="$PTHREAD_LIBS $LIBS" # CFLAGS="$CFLAGS $PTHREAD_CFLAGS" # CC="$PTHREAD_CC" # # In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant # has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to that name # (e.g. PTHREAD_CREATE_UNDETACHED on AIX). # # Also HAVE_PTHREAD_PRIO_INHERIT is defined if pthread is found and the # PTHREAD_PRIO_INHERIT symbol is defined when compiling with # PTHREAD_CFLAGS. # # ACTION-IF-FOUND is a list of shell commands to run if a threads library # is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it # is not found. If ACTION-IF-FOUND is not specified, the default action # will define HAVE_PTHREAD. # # Please let the authors know if this macro fails on any platform, or if # you have any other suggestions or comments. This macro was based on work # by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help # from M. Frigo), as well as ac_pthread and hb_pthread macros posted by # Alejandro Forero Cuervo to the autoconf macro repository. We are also # grateful for the helpful feedback of numerous users. # # Updated for Autoconf 2.68 by Daniel Richard G. # # LICENSE # # Copyright (c) 2008 Steven G.

It fires # the warning (with _au_warn_XXX), outputs it into the # updated configure.ac (with AC_DIAGNOSE), and then outputs # the replacement expansion. # This is an auxiliary macro that is also run when # autoupdate runs m4. It simply calls m4_warning, but # we need a wrapper so that each warning is emitted only # once. We break the quoting in m4_warning's argument in # order to expand this macro's arguments, not AU_DEFUN's. # Finally, this is the expansion that is picked up by # autoconf. It tells the user to run autoupdate, and # then outputs the replacement expansion. We do not care # about autoupdate's warning because that contains # information on what to do *after* running autoupdate. # Make sure we can run config.sub. $SHELL "$ac_aux_dir/config.sub" sun4 >/dev/null 2>&1 || as_fn_error $?

Default is true\. . .TP \fB\-a \-\-all\-types\fR Search all files\. This doesn\'t include hidden files, and doesn\'t respect any ignore files\. . .TP \fB\-A \-\-after [LINES]\fR Print lines after match\. If not provided, LINES defaults to 2\. . .TP \fB\-B \-\-before [LINES]\fR Print lines before match\. If not provided, LINES defaults to 2\. . .TP \fB\-\-[no]break\fR Print a newline between matches in different files\. Enabled by default\. . .TP \fB\-c \-\-count\fR Only print the number of matches in each file\. Note: This is the number of matches, \fBnot\fR the number of matching lines\. Pipe output to \fBwc \-l\fR if you want the number of matching lines\. . .TP \fB\-\-[no]color\fR Print color codes in results\. Enabled by default\. . .TP \fB\-\-color\-line\-number\fR Color codes for line numbers\. Default is 1;33\. . .TP \fB\-\-color\-match\fR Color codes for result match numbers\. Default is 30;43\. . .TP \fB\-\-color\-path\fR Color codes for path names\. Default is 1;32\. . .TP \fB\-\-column\fR Print column numbers in results\. . .TP \fB\-C \-\-context [LINES]\fR Print lines before and after matches\. Default is 2\. . .TP \fB\-D \-\-debug\fR Output ridiculous amounts of debugging info\. Not useful unless you\'re actually debugging\. . .TP \fB\-\-depth NUM\fR Search up to NUM directories deep, \-1 for unlimited\. Default is 25\. . .TP \fB\-\-[no]filename\fR Print file names\. Enabled by default, except when searching a single file\. . .TP \fB\-f \-\-[no]follow\fR Follow symlinks\. Default is false\. . .TP \fB\-F \-\-fixed\-strings\fR Alias for \-\-literal for compatibility with grep\. . .TP \fB\-\-[no]group\fR The default, \fB\-\-group\fR, lumps multiple matches in the same file together, and presents them under a single occurrence of the filename\. \fB\-\-nogroup\fR refrains from this, and instead places the filename at the start of each match line\. . .TP \fB\-g PATTERN\fR Print filenames matching PATTERN\. . .TP \fB\-G \-\-file\-search\-regex PATTERN\fR Only search files whose names match PATTERN\. . .TP \fB\-H \-\-[no]heading\fR Print filenames above matching contents\. . .TP \fB\-\-hidden\fR Search hidden files\. This option obeys ignored files\. . .TP \fB\-\-ignore PATTERN\fR Ignore files/directories whose names match this pattern\. Literal file and directory names are also allowed\. . .TP \fB\-\-ignore\-dir NAME\fR Alias for \-\-ignore for compatibility with ack\. . .TP \fB\-i \-\-ignore\-case\fR Match case\-insensitively\. . .TP \fB\-l \-\-files\-with\-matches\fR Only print the names of files containing matches, not the matching lines\. An empty query will print all files that would be searched\. . .TP \fB\-L \-\-files\-without\-matches\fR Only print the names of files that don\'t contain matches\. . .TP \fB\-\-list\-file\-types\fR See \fBFILE TYPES\fR below\. . .TP \fB\-m \-\-max\-count NUM\fR Skip the rest of a file after NUM matches\. Default is 0, which never skips\. . .TP \fB\-\-[no]mmap\fR Toggle use of memory\-mapped I/O\. Defaults to true on platforms where \fBmmap()\fR is faster than \fBread()\fR\. (All but macOS\.) . .TP \fB\-\-[no]multiline\fR Match regexes across newlines\. Enabled by default\. . .TP \fB\-n \-\-norecurse\fR Don\'t recurse into directories\. . .TP \fB\-\-[no]numbers\fR Print line numbers\. Default is to omit line numbers when searching streams\. . .TP \fB\-o \-\-only\-matching\fR Print only the matching part of the lines\. . .TP \fB\-\-one\-device\fR When recursing directories, don\'t scan dirs that reside on other storage devices\. This lets you avoid scanning slow network mounts\. This feature is not supported on all platforms\. . .TP \fB\-p \-\-path\-to\-ignore STRING\fR Provide a path to a specific \.ignore file\. . .TP \fB\-\-pager COMMAND\fR Use a pager such as \fBless\fR\. Use \fB\-\-nopager\fR to override\. This option is also ignored if output is piped to another program\. . .TP \fB\-\-parallel\fR Parse the input stream as a search term, not data to search\. This is meant to be used with tools such as GNU parallel\. For example: \fBecho "foo\enbar\enbaz" | parallel "ag {} \."\fR will run 3 instances of ag, searching the current directory for "foo", "bar", and "baz"\. . .TP \fB\-\-print\-long\-lines\fR Print matches on very long lines (> 2k characters by default)\. . .TP \fB\-\-passthrough \-\-passthru\fR When searching a stream, print all lines even if they don\'t match\. . .TP \fB\-Q \-\-literal\fR Do not parse PATTERN as a regular expression\. Try to match it literally\. . .TP \fB\-r \-\-recurse\fR Recurse into directories when searching\. Default is true\. . .TP \fB\-s \-\-case\-sensitive\fR Match case\-sensitively\. . .TP \fB\-S \-\-smart\-case\fR Match case\-sensitively if there are any uppercase letters in PATTERN, case\-insensitively otherwise\. Enabled by default\. . .TP \fB\-\-search\-binary\fR Search binary files for matches\. . .TP \fB\-\-silent\fR Suppress all log messages, including errors\. . .TP \fB\-\-stats\fR Print stats (files scanned, time taken, etc)\. . .TP \fB\-\-stats\-only\fR Print stats (files scanned, time taken, etc) and nothing else\. . .TP \fB\-t \-\-all\-text\fR Search all text files\. This doesn\'t include hidden files\. . .TP \fB\-u \-\-unrestricted\fR Search \fIall\fR files\. This ignores \.ignore, \.gitignore, etc\. It searches binary and hidden files as well\. . .TP \fB\-U \-\-skip\-vcs\-ignores\fR Ignore VCS ignore files (\.gitignore, \.hgignore), but still use \.ignore\. . .TP \fB\-v \-\-invert\-match\fR Match every line \fInot\fR containing the specified pattern\. . .TP \fB\-V \-\-version\fR Print version info\. . .TP \fB\-\-vimgrep\fR Output results in the same form as Vim\'s \fB:vimgrep /pattern/g\fR . .IP Here is a ~/\.vimrc configuration example: . .IP \fBset grepprg=ag\e \-\-vimgrep\e $*\fR \fBset grepformat=%f:%l:%c:%m\fR . .IP Then use \fB:grep\fR to grep for something\. Then use \fB:copen\fR, \fB:cn\fR, \fB:cp\fR, etc\. to navigate through the matches\. . .TP \fB\-w \-\-word\-regexp\fR Only match whole words\. . .TP \fB\-\-workers NUM\fR Use NUM worker threads\. Default is the number of CPU cores, with a max of 8\. . .TP \fB\-z \-\-search\-zip\fR Search contents of compressed files\. Currently, gz and xz are supported\. This option requires that ag is built with lzma and zlib\. . .TP \fB\-0 \-\-null \-\-print0\fR Separate the filenames with \fB\e0\fR, rather than \fB\en\fR: this allows \fBxargs \-0 \fR to correctly process filenames containing spaces or newlines\. . .SH "FILE TYPES" It is possible to restrict the types of files searched\. For example, passing \fB\-\-html\fR will search only files with the extensions \fBhtm\fR, \fBhtml\fR, \fBshtml\fR or \fBxhtml\fR\. For a list of supported types, run \fBag \-\-list\-file\-types\fR\. . .SH "IGNORING FILES" By default, ag will ignore files whose names match patterns in \.gitignore, \.hgignore, or \.ignore\. These files can be anywhere in the directories being searched\. Binary files are ignored by default as well\. Finally, ag looks in $HOME/\.agignore for ignore patterns\. . .P If you want to ignore \.gitignore and \.hgignore, but still take \.ignore into account, use \fB\-U\fR\. . .P Use the \fB\-t\fR option to search all text files; \fB\-a\fR to search all files; and \fB\-u\fR to search all, including hidden files\. . .SH "EXAMPLES" \fBag printf\fR: Find matches for "printf" in the current directory\. . .P \fBag foo /bar/\fR: Find matches for "foo" in path /bar/\. . .P \fBag \-\- \-\-foo\fR: Find matches for "\-\-foo" in the current directory\. (As with most UNIX command line utilities, "\-\-" is used to signify that the remaining arguments should not be treated as options\.) . .SH "ABOUT" ag was originally created by Geoff Greer\.

[![Build Status](https://travis-ci.org/ggreer/the_silver_searcher.svg?branch=master)](https://travis-ci.org/ggreer/the_silver_searcher) [![Floobits Status](https://floobits.com/ggreer/ag.svg)](https://floobits.com/ggreer/ag/redirect) [![#ag on Freenode](https://img.shields.io/badge/Freenode-%23ag-brightgreen.svg)](https://webchat.freenode.net/?channels=ag) Do you know C? Want to improve ag? [I invite you to pair with me](http://geoff.greer.fm/2014/10/13/help-me-get-to-ag-10/). ## What's so great about Ag? * It is an order of magnitude faster than `ack`. * It ignores file patterns from your `.gitignore` and `.hgignore`. * If there are files in your source repo you don't want to search, just add their patterns to a `.ignore` file. (\*cough\* `*.min.js` \*cough\*) * The command name is 33% shorter than `ack`, and all keys are on the home row! Ag is quite stable now. Most changes are new features, minor bug fixes, or performance improvements. It's much faster than Ack in my benchmarks: ack test_blah ~/code/ 104.66s user 4.82s system 99% cpu 1:50.03 total ag test_blah ~/code/ 4.67s user 4.58s system 286% cpu 3.227 total Ack and Ag found the same results, but Ag was 34x faster (3.2 seconds vs 110 seconds). My `~/code` directory is about 8GB. Thanks to git/hg/ignore, Ag only searched 700MB of that. There are also [graphs of performance across releases](http://geoff.greer.fm/ag/speed/). ## How is it so fast? * Ag uses [Pthreads](https://en.wikipedia.org/wiki/POSIX_Threads) to take advantage of multiple CPU cores and search files in parallel. * Files are `mmap()`ed instead of read into a buffer. * Literal string searching uses [Boyer-Moore strstr](https://en.wikipedia.org/wiki/Boyer%E2%80%93Moore_string_search_algorithm). * Regex searching uses [PCRE's JIT compiler](http://sljit.sourceforge.net/pcre.html) (if Ag is built with PCRE >=8.21). * Ag calls `pcre_study()` before executing the same regex on every file. * Instead of calling `fnmatch()` on every pattern in your ignore files, non-regex patterns are loaded into arrays and binary searched. I've written several blog posts showing how I've improved performance. These include how I [added pthreads](http://geoff.greer.fm/2012/09/07/the-silver-searcher-adding-pthreads/), [wrote my own `scandir()`](http://geoff.greer.fm/2012/09/03/profiling-ag-writing-my-own-scandir/), [benchmarked every revision to find performance regressions](http://geoff.greer.fm/2012/08/25/the-silver-searcher-benchmarking-revisions/), and profiled with [gprof](http://geoff.greer.fm/2012/02/08/profiling-with-gprof/) and [Valgrind](http://geoff.greer.fm/2012/01/23/making-programs-faster-profiling/). ## Installing ### macOS brew install the_silver_searcher or port install the_silver_searcher ### Linux * Ubuntu >= 13.10 (Saucy) or Debian >= 8 (Jessie) apt-get install silversearcher-ag * Fedora 21 and lower yum install the_silver_searcher * Fedora 22+ dnf install the_silver_searcher * RHEL7+ yum install epel-release.noarch the_silver_searcher * Gentoo emerge -a sys-apps/the_silver_searcher * Arch pacman -S the_silver_searcher * Slackware sbopkg -i the_silver_searcher * openSUSE: zypper install the_silver_searcher * CentOS: yum install the_silver_searcher * SUSE Linux Enterprise: Follow [these simple instructions](https://software.opensuse.org/download.html?project=utilities&package=the_silver_searcher). ### BSD * FreeBSD pkg install the_silver_searcher * OpenBSD/NetBSD pkg_add the_silver_searcher ### Windows * Win32/64 Unofficial daily builds are [available](https://github.com/k-takata/the_silver_searcher-win32). * Chocolatey choco install ag * MSYS2 pacman -S mingw-w64-{i686,x86_64}-ag * Cygwin Run the relevant [`setup-*.exe`](https://cygwin.com/install.html), and select "the\_silver\_searcher" in the "Utils" category. ## Building from source ### Building master 1. Install dependencies (Automake, pkg-config, PCRE, LZMA): * macOS: brew install automake pkg-config pcre xz or port install automake pkgconfig pcre xz * Ubuntu/Debian: apt-get install -y automake pkg-config libpcre3-dev zlib1g-dev liblzma-dev * Fedora: yum -y install pkgconfig automake gcc zlib-devel pcre-devel xz-devel * CentOS: yum -y groupinstall "Development Tools" yum -y install pcre-devel xz-devel * openSUSE: zypper source-install --build-deps-only the_silver_searcher * Windows: It's complicated. See [this wiki page](https://github.com/ggreer/the_silver_searcher/wiki/Windows). 2. Run the build script (which just runs aclocal, automake, etc): ./build.sh On Windows (inside an msys/MinGW shell): make -f Makefile.w32 3. Make install: sudo make install ### Building a release tarball GPG-signed releases are available [here](http://geoff.greer.fm/ag). Building release tarballs requires the same dependencies, except for automake and pkg-config. Once you've installed the dependencies, just run: ./configure make make install You may need to use `sudo` or run as root for the make install. ## Editor Integration ### Vim You can use Ag with [ack.vim](https://github.com/mileszs/ack.vim) by adding the following line to your `.vimrc`: let g:ackprg = 'ag --nogroup --nocolor --column' or: let g:ackprg = 'ag --vimgrep' Which has the same effect but will report every match on the line. ### Emacs You can use [ag.el][] as an Emacs front-end to Ag. See also: [helm-ag]. [ag.el]: https://github.com/Wilfred/ag.el [helm-ag]: https://github.com/syohex/emacs-helm-ag ### TextMate TextMate users can use Ag with [my fork](https://github.com/ggreer/AckMate) of the popular AckMate plugin, which lets you use both Ack and Ag for searching. If you already have AckMate you just want to replace Ack with Ag, move or delete `"~/Library/Application Support/TextMate/PlugIns/AckMate.tmplugin/Contents/Resources/ackmate_ack"` and run `ln -s /usr/local/bin/ag "~/Library/Application Support/TextMate/PlugIns/AckMate.tmplugin/Contents/Resources/ackmate_ack"` ## Other stuff you might like * [Ack](https://github.com/petdance/ack2) - Better than grep. Without Ack, Ag would not exist. * [ack.vim](https://github.com/mileszs/ack.vim) * [Exuberant Ctags](http://ctags.sourceforge.net/) - Faster than Ag, but it builds an index beforehand. Good for *really* big codebases. * [Git-grep](http://git-scm.com/docs/git-grep) - As fast as Ag but only works on git repos. * [ripgrep](https://github.com/BurntSushi/ripgrep) * [Sack](https://github.com/sampson-chen/sack) - A utility that wraps Ack and Ag. It removes a lot of repetition from searching and opening matching files.
