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".

The value is a space-separated list of zero or + more of the values "tar", "tar.gz", "tar.bz2", "tar.lz", "tar.xz", + "tar.zst" and "zip". The special value "all" enables all snapshot + formats. Default value: none. + All compressors use default settings. Some settings can be influenced + with environment variables, for example set ZSTD_CLEVEL=10 in web + server environment for higher (but slower) zstd compression. + +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.

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".

Default + value: global logo-link. + +repo.module-link:: + Text which will be used as the formatstring for a hyperlink when a + submodule is printed in a directory listing. The arguments for the + formatstring are the path and SHA1 of the submodule commit. Default + value: <module-link> + +repo.module-link.<path>:: + Text which will be used as the formatstring for a hyperlink when a + submodule with the specified subdirectory path is printed in a + directory listing. The only argument for the formatstring is the SHA1 + of the submodule commit. Default value: none. + +repo.max-stats:: + Override the default maximum statistics period.

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 head giving in query or + 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: <readme>. + +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: + <snapshots>. + +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: <empty> 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.
