Blank lines, and lines starting with '#', are ignored. LOCATION -------- The default location of cgitrc, defined at compile time, is /etc/cgitrc. At runtime, cgit will consult the environment variable CGIT_CONFIG and, if defined, use its value instead. GLOBAL SETTINGS --------------- about-filter:: Specifies a command which will be invoked to format the content of about pages (both top-level and for each repository). The command will get the content of the about-file on its STDIN, and the STDOUT from the command will be included verbatim on the about page. Default value: none. agefile:: Specifies a path, relative to each repository path, which can be used to specify the date and time of the youngest commit in the repository. The first line in the file is used as input to the "parse_date" function in libgit. Recommended timestamp-format is "yyyy-mm-dd hh:mm:ss". Default value: "info/web/last-modified". cache-root:: Path used to store the cgit cache entries. Default value: "/var/cache/cgit". cache-dynamic-ttl:: Number which specifies the time-to-live, in minutes, for the cached version of repository pages accessed without a fixed SHA1. Default value: "5". cache-repo-ttl:: Number which specifies the time-to-live, in minutes, for the cached version of the repository summary page. Default value: "5". cache-root-ttl:: Number which specifies the time-to-live, in minutes, for the cached version of the repository index page. Default value: "5". cache-scanrc-ttl:: Number which specifies the time-to-live, in minutes, for the result of scanning a path for git repositories. Default value: "15". cache-size:: The maximum number of entries in the cgit cache. Default value: "0" (i.e. caching is disabled). cache-static-ttl:: Number which specifies the time-to-live, in minutes, for the cached version of repository pages accessed with a fixed SHA1. Default value: "5". clone-prefix:: Space-separated list of common prefixes which, when combined with a repository url, generates valid clone urls for the repository. This setting is only used if `repo.clone-url` is unspecified. Default value: none. commit-filter:: Specifies a command which will be invoked to format commit messages. The command will get the message on its STDIN, and the STDOUT from the command will be included verbatim as the commit message, i.e. this can be used to implement bugtracker integration. Default value: none. css:: Url which specifies the css document to include in all cgit pages. Default value: "/cgit.css". embedded:: Flag which, when set to "1", will make cgit generate a html fragment suitable for embedding in other html pages. Default value: none. See also: "noheader". enable-filter-overrides:: Flag which, when set to "1", allows all filter settings to be overridden in repository-specific cgitrc files. Default value: none. enable-index-links:: Flag which, when set to "1", will make cgit generate extra links for each repo in the repository index (specifically, to the "summary", "commit" and "tree" pages). Default value: "0". enable-log-filecount:: Flag which, when set to "1", will make cgit print the number of modified files for each commit on the repository log page. Default value: "0". enable-log-linecount:: Flag which, when set to "1", will make cgit print the number of added and removed lines for each commit on the repository log page. Default value: "0". +enable-remote-branches:: + Flag which, when set to "1", will make cgit display remote branches + in the summary and refs views. Default value: "0". See also: + "repo.enable-remote-branches". + enable-tree-linenumbers:: Flag which, when set to "1", will make cgit generate linenumber links for plaintext blobs printed in the tree view. Default value: "1". favicon:: Url used as link to a shortcut icon for cgit. If specified, it is suggested to use the value "/favicon.ico" since certain browsers will ignore other values. Default value: none. footer:: The content of the file specified with this option will be included verbatim at the bottom of all pages (i.e. it replaces the standard "generated by..." message. Default value: none. head-include:: The content of the file specified with this option will be included verbatim in the html HEAD section on all pages.

This is used by the `plain` command when returning blob content. 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: "./?repo=%s&page=commit&id=%s" nocache:: If set to the value "1" caching will be disabled. This settings is deprecated, and will not be honored starting with cgit-1.0. Default value: "0". noplainemail:: If set to "1" showing full author email adresses 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.

Default value: none. +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 generated by cgit. The value is a space-separated list of zero or more of the values "tar", "tar.gz", "tar.bz2" and "zip". 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. 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". 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.

If no such branch exists in the repository, the first branch name (when sorted) is used as default instead. Default value: "master". repo.desc:: The value to show as repository description. 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: none. repo.name:: The value to show as repository name. Default value: <repo.url>. repo.owner:: A value used to identify the owner of the repository. Default value: none. repo.path:: An absolute path to the repository directory. For non-bare repositories this is the .git-directory.

Default value: <snapshots>. repo.section:: Override the current section name for this repository. Default value: none. repo.source-filter:: Override the default source-filter. Default value: none. See also: "enable-filter-overrides". 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".
