Runtime configuration for cgit
Cgitrc contains all runtime settings for cgit, including the list of git repositories, formatted as a line-separated list of NAME=VALUE pairs. Blank lines, and lines starting with #, are ignored.
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.
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, the name of the file as the first argument, and the STDOUT from the command will be included verbatim on the about page. Default value: none. See also: "FILTER API".
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". You may want to generate this file from a post-receive hook. Default value: "info/web/last-modified".
auth-filter
Specifies a command that will be invoked for authenticating repository access. Receives quite a few arguments, and data on both stdin and stdout for authentication processing. Details follow later in this document. If no auth-filter is specified, no authentication is performed. Default value: none. See also: "FILTER API".

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

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\(cqs EXPORT_OK and STRICT_EXPORT functionality and limit cgit\(cqs 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.
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. Default value: "name".

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.

Override the default maximum statistics period. Valid values are equal to the values specified for the global "max-stats" setting. 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.

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 <repo.path>) 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: <readme>.

repo.url
The relative url used to access the repository. This must be the first setting specified for each repo. Default value: none.
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".
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\(cqs 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.
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 relevent 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.
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.
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\(cqd parameters on standard input, and should write a complete CGI request, 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.
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.
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
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.

Comments currently cannot appear on the same line as a setting; the comment will be included as part of the value. E.g. this line:
robots=index # allow indexing
will generate the following html element:
<meta name='robots' content='index # allow indexing'/>
