Default value: "50". max-repodesc-length:: Specifies the maximum number of repo description characters to display on the repository index page. Default value: "80". max-blob-size:: Specifies the maximum size of a blob to display HTML for in KBytes. Default value: "0" (limit disabled). max-stats:: Set the default maximum statistics period. Valid values are "week", "month", "quarter" and "year". If unspecified, statistics are disabled. Default value: none. See also: "repo.max-stats". mimetype.<ext>:: Set the mimetype for the specified filename extension. 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. See also: "embedded". 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". repo.group:: Legacy alias for "section". This option is deprecated and will not be supported in cgit-1.0. robots:: Text used as content for the "robots" meta-tag. Default value: "index, nofollow". root-desc:: Text printed below the heading on the repository index page. 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-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. Default value: none. See also: cache-scanrc-ttl. section:: The name of the current repository section - all repositories defined after this option will inherit the current section name. 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. REPOSITORY SETTINGS ------------------- repo.about-filter:: Override the default about-filter. Default value: none. See also: "enable-filter-overrides". repo.clone-url:: A list of space-separated urls which can be used to clone this repo. Default value: none. repo.commit-filter:: Override the default commit-filter. Default value: none. See also: "enable-filter-overrides". 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: "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.max-stats:: 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. 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 <repo.path>) which specifies a file to include verbatim as the "About" page for this repo. Default value: none. repo.snapshots:: A mask of allowed snapshot-formats for this repo, restricted by the "snapshots" global setting. 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.
