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 Lesser 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. + + + Copyright (C) + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 2 of the License, or + (at your option) any later version. + + This program 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 General Public License for more details. + + You should have received a copy of the GNU General Public License along + with this program; if not, write to the Free Software Foundation, Inc., + 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA. + +Also add information on how to contact you by electronic and paper mail. + +If the program is interactive, make it output a short notice like this +when it starts in an interactive mode: + + Gnomovision version 69, Copyright (C) year name of author + Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. + This is free software, and you are welcome to redistribute it + under certain conditions; type `show c' for details. + +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.

The arguments for the + formatstring are the path and SHA1 of the submodule commit. Default + value: none. + +noplainemail:: + If set to "1" showing full author email addresses will be disabled. + Default value: "0". + +noheader:: + Flag which, when set to "1", will make cgit omit the standard header + on all pages. Default value: none. See also: "embedded". + +owner-filter:: + Specifies a command which will be invoked to format the Owner + column of the main page. The command will get the owner on STDIN, + and the STDOUT from the command will be included verbatim in the + table. This can be used to link to additional context such as an + owners home page. When active this filter is used instead of the + default owner query url. Default value: none. + See also: "FILTER API". + +project-list:: + A list of subdirectories inside of scan-path, relative to it, that + should loaded as git repositories. This must be defined prior to + scan-path. Default value: none. See also: scan-path, "MACRO + EXPANSION". + +readme:: + Text which will be used as default value for "repo.readme". Multiple + config keys may be specified, and cgit will use the first found file + in this list. This is useful in conjunction with scan-path. Default + value: none. See also: scan-path, repo.readme. + +remove-suffix:: + If set to "1" and scan-path is enabled, if any repositories are found + with a suffix of ".git", this suffix will be removed for the url and + name. This must be defined prior to scan-path. Default value: "0". + See also: scan-path. + +renamelimit:: + Maximum number of files to consider when detecting renames. The value + "-1" uses the compiletime value in git (for further info, look at + `man git-diff`). Default value: "-1". + +repository-sort:: + The way in which repositories in each section are sorted. Valid values + are "name" for sorting by the repo name or "age" for sorting by the + most recently updated repository. Default value: "name". See also: + section, case-sensitive-sort, section-sort. + +robots:: + Text used as content for the "robots" meta-tag.

Default + value: "a fast webinterface for the git dscm". + +root-readme:: + The content of the file specified with this option will be included + verbatim below the "about" link on the repository index page. Default + value: none. + +root-title:: + Text printed as heading on the repository index page. Default value: + "Git Repository Browser". + +scan-hidden-path:: + If set to "1" and scan-path is enabled, scan-path will recurse into + directories whose name starts with a period ('.'). Otherwise, + scan-path will stay away from such directories (considered as + "hidden"). Note that this does not apply to the ".git" directory in + non-bare repos. This must be defined prior to scan-path. + Default value: 0. See also: scan-path. + +scan-path:: + A path which will be scanned for repositories. If caching is enabled, + the result will be cached as a cgitrc include-file in the cache + directory. If project-list has been defined prior to scan-path, + scan-path loads only the directories listed in the file pointed to by + project-list. Be advised that only the global settings taken + before the scan-path directive will be applied to each repository. + Default value: none. See also: cache-scanrc-ttl, project-list, + "MACRO EXPANSION". + +section:: + The name of the current repository section - all repositories defined + after this option will inherit the current section name. Default value: + none. + +section-sort:: + Flag which, when set to "1", will sort the sections on the repository + listing by name. Set this flag to "0" if the order in the cgitrc file should + be preserved. Default value: "1". See also: section, + case-sensitive-sort, repository-sort. + +section-from-path:: + A number which, if defined prior to scan-path, specifies how many + path elements from each repo path to use as a default section name. + If negative, cgit will discard the specified number of path elements + above the repo directory. Default value: "0". + +side-by-side-diffs:: + If set to "1" shows side-by-side diffs instead of unidiffs per + default. Default value: "0". + +snapshots:: + Text which specifies the default set of snapshot formats that cgit + generates links for. The value is a space-separated list of zero or + more of the values "tar", "tar.gz", "tar.bz2", "tar.xz" and "zip". + The special value "all" enables all snapshot formats. + Default value: none. + +source-filter:: + Specifies a command which will be invoked to format plaintext blobs + in the tree view. The command will get the blob content on its STDIN + and the name of the blob as its only command line argument. The STDOUT + from the command will be included verbatim as the blob contents, i.e. + this can be used to implement e.g. syntax highlighting. Default value: + none. See also: "FILTER API". + +summary-branches:: + Specifies the number of branches to display in the repository "summary" + view. Default value: "10". + +summary-log:: + Specifies the number of log entries to display in the repository + "summary" view. Default value: "10". + +summary-tags:: + Specifies the number of tags to display in the repository "summary" + view. Default value: "10". + +strict-export:: + Filename which, if specified, needs to be present within the repository + for cgit to allow access to that repository. This can be used to emulate + gitweb's EXPORT_OK and STRICT_EXPORT functionality and limit cgit's + repositories to match those exported by git-daemon. This option must + be defined prior to scan-path. + +virtual-root:: + Url which, if specified, will be used as root for all cgit links. It + will also cause cgit to generate 'virtual urls', i.e. urls like + '/cgit/tree/README' as opposed to '?r=cgit&p=tree&path=README'. Default + value: none. + NOTE: cgit has recently learned how to use PATH_INFO to achieve the + same kind of virtual urls, so this option will probably be deprecated. + + +REPOSITORY SETTINGS +------------------- +repo.about-filter:: + Override the default about-filter. Default value: none. See also: + "enable-filter-overrides". See also: "FILTER API". + +repo.branch-sort:: + Flag which, when set to "age", enables date ordering in the branch ref + list, and when set to "name" enables ordering by branch name.

See also: "FILTER API". + +repo.commit-sort:: + Flag which, when set to "date", enables strict date ordering in the + commit log, and when set to "topo" enables strict topological + ordering. If unset, the default ordering of "git log" is used. Default + value: unset. + +repo.defbranch:: + The name of the default branch for this repository. If no such branch + exists in the repository, the first branch name (when sorted) is used + as default instead. Default value: branch pointed to by HEAD, or + "master" if there is no suitable HEAD. + +repo.desc:: + The value to show as repository description. Default value: none. + +repo.email-filter:: + Override the default email-filter. Default value: none. See also: + "enable-filter-overrides".

Default value: none. + +repo.enable-html-serving:: + A flag which can be used to override the global setting + `enable-html-serving`. Default value: none. + +repo.enable-log-filecount:: + A flag which can be used to disable the global setting + `enable-log-filecount'. Default value: none. + +repo.enable-log-linecount:: + A flag which can be used to disable the global setting + `enable-log-linecount'.

Default value: . + +repo.enable-subject-links:: + A flag which can be used to override the global setting + `enable-subject-links'. Default value: none. + +repo.extra-head-content:: + This value will be added verbatim to the head section of each page + displayed for this repo. Default value: none. + +repo.hide:: + Flag which, when set to "1", hides the repository from the repository + index. The repository can still be accessed by providing a direct path. + Default value: "0". See also: "repo.ignore". + +repo.homepage:: + The value to show as repository homepage. Default value: none. + +repo.ignore:: + Flag which, when set to "1", ignores the repository. The repository + is not shown in the index and cannot be accessed by providing a direct + path.

Default value: . + +repo.owner:: + A value used to identify the owner of the repository. Default value: + none. + +repo.owner-filter:: + Override the default owner-filter. Default value: none. See also: + "enable-filter-overrides". See also: "FILTER API". + +repo.path:: + An absolute path to the repository directory. For non-bare repositories + this is the .git-directory. Default value: none. + +repo.readme:: + A path (relative to ) which specifies a file to include + verbatim as the "About" page for this repo. You may also specify a + git refspec by head or by hash by prepending the refspec followed by + a colon. For example, "master:docs/readme.mkd". If the value begins + with a colon, i.e. ":docs/readme.rst", the default branch of the + repository will be used. Sharing any file will expose that entire + directory tree to the "/about/PATH" endpoints, so be sure that there + are no non-public files located in the same directory as the readme + file. Default value: . + +repo.section:: + Override the current section name for this repository. Default value: + none. + +repo.snapshots:: + A mask of snapshot formats for this repo that cgit generates links for, + restricted by the global "snapshots" setting. Default value: + . + +repo.snapshot-prefix:: + Prefix to use for snapshot links instead of the repository basename. + For example, the "linux-stable" repository may wish to set this to + "linux" so that snapshots are in the format "linux-3.15.4" instead + of "linux-stable-3.15.4". Default value: meaning to use + the repository basename. + +repo.source-filter:: + Override the default source-filter. Default value: none. See also: + "enable-filter-overrides". See also: "FILTER API". + +repo.url:: + The relative url used to access the repository. This must be the first + setting specified for each repo. Default value: none. + + +REPOSITORY-SPECIFIC CGITRC FILE +------------------------------- +When the option "scan-path" is used to auto-discover git repositories, cgit +will try to parse the file "cgitrc" within any found repository. Such a +repo-specific config file may contain any of the repo-specific options +described above, except "repo.url" and "repo.path". Additionally, the "filter" +options are only acknowledged in repo-specific config files when +"enable-filter-overrides" is set to "1". + +Note: the "repo." prefix is dropped from the option names in repo-specific +config files, e.g. "repo.desc" becomes "desc". + + +FILTER API +---------- +By default, filters are separate processes that are executed each time they +are needed. Alternative technologies may be used by prefixing the filter +specification with the relevant string; available values are: + +'exec:':: + The default "one process per filter" mode. + +'lua:':: + Executes the script using a built-in Lua interpreter. The script is + loaded once per execution of cgit, and may be called multiple times + during cgit's lifetime, making it a good choice for repeated filters + such as the 'email filter'. It responds to three functions: + + 'filter_open(argument1, argument2, argument3, ...)':: + This is called upon activation of the filter for a particular + set of data. + 'filter_write(buffer)':: + This is called whenever cgit writes data to the webpage. + 'filter_close()':: + This is called when the current filtering operation is + completed. It must return an integer value. Usually 0 + indicates success. + + Additionally, cgit exposes to the Lua the following built-in functions: + + 'html(str)':: + Writes 'str' to the webpage. + 'html_txt(str)':: + HTML escapes and writes 'str' to the webpage. + 'html_attr(str)':: + HTML escapes for an attribute and writes "str' to the webpage. + 'html_url_path(str)':: + URL escapes for a path and writes 'str' to the webpage. + 'html_url_arg(str)':: + URL escapes for an argument and writes 'str' to the webpage. + 'html_include(file)':: + Includes 'file' in webpage. + + +Parameters are provided to filters as follows. + +about filter:: + This filter is given a single parameter: the filename of the source + file to filter. The filter can use the filename to determine (for + example) the type of syntax to follow when formatting the readme file. + The about text that is to be filtered is available on standard input + and the filtered text is expected on standard output. + +auth filter:: + The authentication filter receives 12 parameters: + - filter action, explained below, which specifies which action the + filter is called for + - http cookie + - http method + - http referer + - http path + - http https flag + - cgit repo + - cgit page + - cgit url + - cgit login url + When the filter action is "body", this filter must write to output the + HTML for displaying the login form, which POSTs to the login url. When + the filter action is "authenticate-cookie", this filter must validate + the http cookie and return a 0 if it is invalid or 1 if it is invalid, + in the exit code / close function. If the filter action is + "authenticate-post", this filter receives POST'd parameters on + standard input, and should write a complete CGI response, preferably + with a 302 redirect, and write to output one or more "Set-Cookie" + HTTP headers, each followed by a newline. + + Please see `filters/simple-authentication.lua` for a clear example + script that may be modified. + +commit filter:: + This filter is given no arguments. The commit message text that is to + be filtered is available on standard input and the filtered text is + expected on standard output. + +email filter:: + This filter is given two parameters: the email address of the relevant + author and a string indicating the originating page. The filter will + then receive the text string to format on standard input and is + expected to write to standard output the formatted text to be included + in the page. + +owner filter:: + This filter is given no arguments. The owner text is available on + standard input and the filter is expected to write to standard + output. The output is included in the Owner column. + +source filter:: + This filter is given a single parameter: the filename of the source + file to filter. The filter can use the filename to determine (for + example) the syntax highlighting mode. The contents of the source + file that is to be filtered is available on standard input and the + filtered contents is expected on standard output. + + +All filters are handed the following environment variables: + +- CGIT_REPO_URL (from repo.url) +- CGIT_REPO_NAME (from repo.name) +- CGIT_REPO_PATH (from repo.path) +- CGIT_REPO_OWNER (from repo.owner) +- CGIT_REPO_DEFBRANCH (from repo.defbranch) +- CGIT_REPO_SECTION (from repo.section) +- CGIT_REPO_CLONE_URL (from repo.clone-url) + +If a setting is not defined for a repository and the corresponding global +setting is also not defined (if applicable), then the corresponding +environment variable will be unset. + + +MACRO EXPANSION +--------------- +The following cgitrc options support a simple macro expansion feature, +where tokens prefixed with "$" are replaced with the value of a similarly +named environment variable: + +- cache-root +- include +- project-list +- scan-path + +Macro expansion will also happen on the content of $CGIT_CONFIG, if +defined. + +One usage of this feature is virtual hosting, which in its simplest form +can be accomplished by adding the following line to /etc/cgitrc: + + include=/etc/cgitrc.d/$HTTP_HOST + +The following options are expanded during request processing, and support +the environment variables defined in "FILTER API": + +- clone-url +- repo.clone-url + + +CACHE +----- + +All cache ttl values are in minutes. Negative ttl values indicate that a page +type will never expire, and thus the first time a URL is accessed, the result +will be cached indefinitely, even if the underlying git repository changes. +Conversely, when a ttl value is zero, the cache is disabled for that +particular page type, and the page type is never cached. + +SIGNATURES +---------- + +Cgit can host .asc signatures corresponding to various snapshot formats, +through use of git notes. For example, the following command may be used to +add a signature to a .tar.xz archive: + + git notes --ref=refs/notes/signatures/tar.xz add -C "$( + gpg --output - --armor --detach-sign cgit-1.1.tar.xz | + git hash-object -w --stdin + )" v1.1 + +If it is instead desirable to attach a signature of the underlying .tar, this +will be linked, as a special case, beside a .tar.* link that does not have its +own signature. For example, a signature of a tarball of the latest tag might +be added with a similar command: + + tag="$(git describe --abbrev=0)" + git notes --ref=refs/notes/signatures/tar add -C "$( + git archive --format tar --prefix "cgit-${tag#v}/" "$tag" | + gpg --output - --armor --detach-sign | + git hash-object -w --stdin + )" "$tag" + +Since git-archive(1) is expected to produce stable output between versions, +this allows one to generate a long-term signature of the contents of a given +tag. + +EXAMPLE CGITRC FILE +------------------- + +.... +# Enable caching of up to 1000 output entries +cache-size=1000 + + +# Specify some default clone urls using macro expansion +clone-url=git://foo.org/$CGIT_REPO_URL git@foo.org:$CGIT_REPO_URL + +# Specify the css url +css=/css/cgit.css + + +# Show owner on index page +enable-index-owner=1 + + +# Allow http transport git clone +enable-http-clone=1 + + +# Show extra links for each repository on the index page +enable-index-links=1 + + +# Enable blame page and create links to it from tree page +enable-blame=1 + + +# Enable ASCII art commit history graph on the log pages +enable-commit-graph=1 + + +# Show number of affected files per commit on the log pages +enable-log-filecount=1 + + +# Show number of added/removed lines per commit on the log pages +enable-log-linecount=1 + + +# Sort branches by date +branch-sort=age + + +# Add a cgit favicon +favicon=/favicon.ico + + +# Use a custom logo +logo=/img/mylogo.png + + +# Enable statistics per week, month and quarter +max-stats=quarter + + +# Set the title and heading of the repository index page +root-title=example.com git repositories + + +# Set a subheading for the repository index page +root-desc=tracking the foobar development + + +# Include some more info about example.com on the index page +root-readme=/var/www/htdocs/about.html + + +# Allow download of tar.gz, tar.bz2 and zip-files +snapshots=tar.gz tar.bz2 zip + + +## +## List of common mimetypes +## + +mimetype.gif=image/gif +mimetype.html=text/html +mimetype.jpg=image/jpeg +mimetype.jpeg=image/jpeg +mimetype.pdf=application/pdf +mimetype.png=image/png +mimetype.svg=image/svg+xml + + +# Highlight source code with python pygments-based highlighter +source-filter=/var/www/cgit/filters/syntax-highlighting.py + +# Format markdown, restructuredtext, manpages, text files, and html files +# through the right converters +about-filter=/var/www/cgit/filters/about-formatting.sh + +## +## Search for these files in the root of the default branch of repositories +## for coming up with the about page: +## +readme=:README.md +readme=:readme.md +readme=:README.mkd +readme=:readme.mkd +readme=:README.rst +readme=:readme.rst +readme=:README.html +readme=:readme.html +readme=:README.htm +readme=:readme.htm +readme=:README.txt +readme=:readme.txt +readme=:README +readme=:readme +readme=:INSTALL.md +readme=:install.md +readme=:INSTALL.mkd +readme=:install.mkd +readme=:INSTALL.rst +readme=:install.rst +readme=:INSTALL.html +readme=:install.html +readme=:INSTALL.htm +readme=:install.htm +readme=:INSTALL.txt +readme=:install.txt +readme=:INSTALL +readme=:install + + +## +## List of repositories. +## PS: Any repositories listed when section is unset will not be +## displayed under a section heading +## PPS: This list could be kept in a different file (e.g. '/etc/cgitrepos') +## and included like this: +## include=/etc/cgitrepos +## + + +repo.url=foo +repo.path=/pub/git/foo.git +repo.desc=the master foo repository +repo.owner=fooman@example.com +repo.readme=info/web/about.html + + +repo.url=bar +repo.path=/pub/git/bar.git +repo.desc=the bars for your foo +repo.owner=barman@example.com +repo.readme=info/web/about.html + + +# The next repositories will be displayed under the 'extras' heading +section=extras + + +repo.url=baz +repo.path=/pub/git/baz.git +repo.desc=a set of extensions for bar users + +repo.url=wiz +repo.path=/pub/git/wiz.git +repo.desc=the wizard of foo + + +# Add some mirrored repositories +section=mirrors + + +repo.url=git +repo.path=/pub/git/git.git +repo.desc=the dscm + + +repo.url=linux +repo.path=/pub/git/linux.git +repo.desc=the kernel + +# Disable adhoc downloads of this repo +repo.snapshots=0 + +# Disable line-counts for this repo +repo.enable-log-linecount=0 + +# Restrict the max statistics period for this repo +repo.max-stats=month +.... + + +BUGS +---- +Comments currently cannot appear on the same line as a setting; the comment +will be included as part of the value.
