NAME

       gitweb.conf - Gitweb (Git web interface) configuration file

SYNOPSIS

       /etc/gitweb.conf, /etc/gitweb-common.conf, $GITWEBDIR/gitweb_config.perl

DESCRIPTION

       The gitweb CGI script for viewing Git repositories over the web uses a perl script
       fragment as its configuration file. You can set variables using "our $variable = value";
       text from a "#" character until the end of a line is ignored. See perlsyn(1) for details.

       An example:

           # gitweb configuration file for http://git.example.org
           #
           our $projectroot = "/srv/git"; # FHS recommendation
           our $site_name = 'Example.org >> Repos';

       The configuration file is used to override the default settings that were built into
       gitweb at the time the gitweb.cgi script was generated.

       While one could just alter the configuration settings in the gitweb CGI itself, those
       changes would be lost upon upgrade. Configuration settings might also be placed into a
       file in the same directory as the CGI script with the default name gitweb_config.perl —
       allowing one to have multiple gitweb instances with different configurations by the use of
       symlinks.

       Note that some configuration can be controlled on per-repository rather than gitweb-wide
       basis: see "Per-repository gitweb configuration" subsection on gitweb(1) manpage.

DISCUSSION

       Gitweb reads configuration data from the following sources in the following order:

       •   built-in values (some set during build stage),

       •   common system-wide configuration file (defaults to /etc/gitweb-common.conf),

       •   either per-instance configuration file (defaults to gitweb_config.perl in the same
           directory as the installed gitweb), or if it does not exists then fallback system-wide
           configuration file (defaults to /etc/gitweb.conf).

       Values obtained in later configuration files override values obtained earlier in the above
       sequence.

       Locations of the common system-wide configuration file, the fallback system-wide
       configuration file and the per-instance configuration file are defined at compile time
       using build-time Makefile configuration variables, respectively GITWEB_CONFIG_COMMON,
       GITWEB_CONFIG_SYSTEM and GITWEB_CONFIG.

       You can also override locations of gitweb configuration files during runtime by setting
       the following environment variables: GITWEB_CONFIG_COMMON, GITWEB_CONFIG_SYSTEM and
       GITWEB_CONFIG to a non-empty value.

       The syntax of the configuration files is that of Perl, since these files are handled by
       sourcing them as fragments of Perl code (the language that gitweb itself is written in).
       Variables are typically set using the our qualifier (as in "our $variable = <value>;") to
       avoid syntax errors if a new version of gitweb no longer uses a variable and therefore
       stops declaring it.

       You can include other configuration file using read_config_file() subroutine. For example,
       one might want to put gitweb configuration related to access control for viewing
       repositories via Gitolite (one of Git repository management tools) in a separate file,
       e.g. in /etc/gitweb-gitolite.conf. To include it, put

           read_config_file("/etc/gitweb-gitolite.conf");

       somewhere in gitweb configuration file used, e.g. in per-installation gitweb configuration
       file. Note that read_config_file() checks itself that the file it reads exists, and does
       nothing if it is not found. It also handles errors in included file.

       The default configuration with no configuration file at all may work perfectly well for
       some installations. Still, a configuration file is useful for customizing or tweaking the
       behavior of gitweb in many ways, and some optional features will not be present unless
       explicitly enabled using the configurable %features variable (see also "Configuring gitweb
       features" section below).

CONFIGURATION VARIABLES

       Some configuration variables have their default values (embedded in the CGI script) set
       during building gitweb — if that is the case, this fact is put in their description. See
       gitweb’s INSTALL file for instructions on building and installing gitweb.

   Location of repositories
       The configuration variables described below control how gitweb finds Git repositories, and
       how repositories are displayed and accessed.

       See also "Repositories" and later subsections in gitweb(1) manpage.

       $projectroot
           Absolute filesystem path which will be prepended to project path; the path to
           repository is $projectroot/$project. Set to $GITWEB_PROJECTROOT during installation.
           This variable has to be set correctly for gitweb to find repositories.

           For example, if $projectroot is set to "/srv/git" by putting the following in gitweb
           config file:

               our $projectroot = "/srv/git";

           then

               http://git.example.com/gitweb.cgi?p=foo/bar.git

           and its path_info based equivalent

               http://git.example.com/gitweb.cgi/foo/bar.git

           will map to the path /srv/git/foo/bar.git on the filesystem.

       $projects_list
           Name of a plain text file listing projects, or a name of directory to be scanned for
           projects.

           Project list files should list one project per line, with each line having the
           following format

               <URI-encoded filesystem path to repository> SP <URI-encoded repository owner>

           The default value of this variable is determined by the GITWEB_LIST makefile variable
           at installation time. If this variable is empty, gitweb will fall back to scanning the
           $projectroot directory for repositories.

       $project_maxdepth
           If $projects_list variable is unset, gitweb will recursively scan filesystem for Git
           repositories. The $project_maxdepth is used to limit traversing depth, relative to
           $projectroot (starting point); it means that directories which are further from
           $projectroot than $project_maxdepth will be skipped.

           It is purely performance optimization, originally intended for MacOS X, where
           recursive directory traversal is slow. Gitweb follows symbolic links, but it detects
           cycles, ignoring any duplicate files and directories.

           The default value of this variable is determined by the build-time configuration
           variable GITWEB_PROJECT_MAXDEPTH, which defaults to 2007.

       $export_ok
           Show repository only if this file exists (in repository). Only effective if this
           variable evaluates to true. Can be set when building gitweb by setting
           GITWEB_EXPORT_OK. This path is relative to GIT_DIR. git-daemon[1] uses
           git-daemon-export-ok, unless started with --export-all. By default this variable is
           not set, which means that this feature is turned off.

       $export_auth_hook
           Function used to determine which repositories should be shown. This subroutine should
           take one parameter, the full path to a project, and if it returns true, that project
           will be included in the projects list and can be accessed through gitweb as long as it
           fulfills the other requirements described by $export_ok, $projects_list, and
           $projects_maxdepth. Example:

               our $export_auth_hook = sub { return -e "$_[0]/git-daemon-export-ok"; };

           though the above might be done by using $export_ok instead

               our $export_ok = "git-daemon-export-ok";

           If not set (default), it means that this feature is disabled.

           See also more involved example in "Controlling access to Git repositories" subsection
           on gitweb(1) manpage.

       $strict_export
           Only allow viewing of repositories also shown on the overview page. This for example
           makes $gitweb_export_ok file decide if repository is available and not only if it is
           shown. If $gitweb_list points to file with list of project, only those repositories
           listed would be available for gitweb. Can be set during building gitweb via
           GITWEB_STRICT_EXPORT. By default this variable is not set, which means that you can
           directly access those repositories that are hidden from projects list page (e.g. the
           are not listed in the $projects_list file).

   Finding files
       The following configuration variables tell gitweb where to find files. The values of these
       variables are paths on the filesystem.

       $GIT
           Core git executable to use. By default set to $GIT_BINDIR/git, which in turn is by
           default set to $(bindir)/git. If you use Git installed from a binary package, you
           should usually set this to "/usr/bin/git". This can just be "git" if your web server
           has a sensible PATH; from security point of view it is better to use absolute path to
           git binary. If you have multiple Git versions installed it can be used to choose which
           one to use. Must be (correctly) set for gitweb to be able to work.

       $mimetypes_file
           File to use for (filename extension based) guessing of MIME types before trying
           /etc/mime.types.  NOTE that this path, if relative, is taken as relative to the
           current Git repository, not to CGI script. If unset, only /etc/mime.types is used (if
           present on filesystem). If no mimetypes file is found, mimetype guessing based on
           extension of file is disabled. Unset by default.

       $highlight_bin
           Path to the highlight executable to use (it must be the one from
           http://www.andre-simon.de due to assumptions about parameters and output). By default
           set to highlight; set it to full path to highlight executable if it is not installed
           on your web server’s PATH. Note that highlight feature must be set for gitweb to
           actually use syntax highlighting.

           NOTE: if you want to add support for new file type (supported by "highlight" but not
           used by gitweb), you need to modify %highlight_ext or %highlight_basename, depending
           on whether you detect type of file based on extension (for example "sh") or on its
           basename (for example "Makefile"). The keys of these hashes are extension and
           basename, respectively, and value for given key is name of syntax to be passed via
           --syntax <syntax> to highlighter.

           For example if repositories you are hosting use "phtml" extension for PHP files, and
           you want to have correct syntax-highlighting for those files, you can add the
           following to gitweb configuration:

               our %highlight_ext;
               $highlight_ext{'phtml'} = 'php';

   Links and their targets
       The configuration variables described below configure some of gitweb links: their target
       and their look (text or image), and where to find page prerequisites (stylesheet, favicon,
       images, scripts). Usually they are left at their default values, with the possible
       exception of @stylesheets variable.

       @stylesheets
           List of URIs of stylesheets (relative to the base URI of a page). You might specify
           more than one stylesheet, for example to use "gitweb.css" as base with site specific
           modifications in a separate stylesheet to make it easier to upgrade gitweb. For
           example, you can add a site stylesheet by putting

               push @stylesheets, "gitweb-site.css";

           in the gitweb config file. Those values that are relative paths are relative to base
           URI of gitweb.

           This list should contain the URI of gitweb’s standard stylesheet. The default URI of
           gitweb stylesheet can be set at build time using the GITWEB_CSS makefile variable. Its
           default value is static/gitweb.css (or static/gitweb.min.css if the CSSMIN variable is
           defined, i.e. if CSS minifier is used during build).

           Note: there is also a legacy $stylesheet configuration variable, which was used by
           older gitweb. If $stylesheet variable is defined, only CSS stylesheet given by this
           variable is used by gitweb.

       $logo
           Points to the location where you put git-logo.png on your web server, or to be more
           the generic URI of logo, 72x27 size). This image is displayed in the top right corner
           of each gitweb page and used as a logo for the Atom feed. Relative to the base URI of
           gitweb (as a path). Can be adjusted when building gitweb using GITWEB_LOGO variable By
           default set to static/git-logo.png.

       $favicon
           Points to the location where you put git-favicon.png on your web server, or to be more
           the generic URI of favicon, which will be served as "image/png" type. Web browsers
           that support favicons (website icons) may display them in the browser’s URL bar and
           next to the site name in bookmarks. Relative to the base URI of gitweb. Can be
           adjusted at build time using GITWEB_FAVICON variable. By default set to
           static/git-favicon.png.

       $javascript
           Points to the location where you put gitweb.js on your web server, or to be more
           generic the URI of JavaScript code used by gitweb. Relative to the base URI of gitweb.
           Can be set at build time using the GITWEB_JS build-time configuration variable.

           The default value is either static/gitweb.js, or static/gitweb.min.js if the JSMIN
           build variable was defined, i.e. if JavaScript minifier was used at build time.  Note
           that this single file is generated from multiple individual JavaScript "modules".

       $home_link
           Target of the home link on the top of all pages (the first part of view
           "breadcrumbs"). By default it is set to the absolute URI of a current page (to the
           value of $my_uri variable, or to "/" if $my_uri is undefined or is an empty string).

       $home_link_str
           Label for the "home link" at the top of all pages, leading to $home_link (usually the
           main gitweb page, which contains the projects list). It is used as the first component
           of gitweb’s "breadcrumb trail": <home link> / <project> / <action>. Can be set at
           build time using the GITWEB_HOME_LINK_STR variable. By default it is set to
           "projects", as this link leads to the list of projects. Another popular choice is to
           set it to the name of site. Note that it is treated as raw HTML so it should not be
           set from untrusted sources.

       @extra_breadcrumbs
           Additional links to be added to the start of the breadcrumb trail before the home
           link, to pages that are logically "above" the gitweb projects list, such as the
           organization and department which host the gitweb server. Each element of the list is
           a reference to an array, in which element 0 is the link text (equivalent to
           $home_link_str) and element 1 is the target URL (equivalent to $home_link).

           For example, the following setting produces a breadcrumb trail like "home / dev /
           projects / ..." where "projects" is the home link.

               our @extra_breadcrumbs = (
                 [ 'home' => 'https://www.example.org/' ],
                 [ 'dev'  => 'https://dev.example.org/' ],
               );

       $logo_url, $logo_label
           URI and label (title) for the Git logo link (or your site logo, if you chose to use
           different logo image). By default, these both refer to Git homepage,
           http://git-scm.com; in the past, they pointed to Git documentation at
           http://www.kernel.org.

   Changing gitweb’s look
       You can adjust how pages generated by gitweb look using the variables described below. You
       can change the site name, add common headers and footers for all pages, and add a
       description of this gitweb installation on its main page (which is the projects list
       page), etc.

       $site_name
           Name of your site or organization, to appear in page titles. Set it to something
           descriptive for clearer bookmarks etc. If this variable is not set or is, then gitweb
           uses the value of the SERVER_NAME CGI environment variable, setting site name to
           "$SERVER_NAME Git", or "Untitled Git" if this variable is not set (e.g. if running
           gitweb as standalone script).

           Can be set using the GITWEB_SITENAME at build time. Unset by default.

       $site_html_head_string
           HTML snippet to be included in the <head> section of each page. Can be set using
           GITWEB_SITE_HTML_HEAD_STRING at build time. No default value.

       $site_header
           Name of a file with HTML to be included at the top of each page. Relative to the
           directory containing the gitweb.cgi script. Can be set using GITWEB_SITE_HEADER at
           build time. No default value.

       $site_footer
           Name of a file with HTML to be included at the bottom of each page. Relative to the
           directory containing the gitweb.cgi script. Can be set using GITWEB_SITE_FOOTER at
           build time. No default value.

       $home_text
           Name of a HTML file which, if it exists, is included on the gitweb projects overview
           page ("projects_list" view). Relative to the directory containing the gitweb.cgi
           script. Default value can be adjusted during build time using GITWEB_HOMETEXT
           variable. By default set to indextext.html.

       $projects_list_description_width
           The width (in characters) of the "Description" column of the projects list. Longer
           descriptions will be truncated (trying to cut at word boundary); the full description
           is available in the title attribute (usually shown on mouseover). The default is 25,
           which might be too small if you use long project descriptions.

       $default_projects_order
           Default value of ordering of projects on projects list page, which means the ordering
           used if you don’t explicitly sort projects list (if there is no "o" CGI query
           parameter in the URL). Valid values are "none" (unsorted), "project" (projects are by
           project name, i.e. path to repository relative to $projectroot), "descr" (project
           description), "owner", and "age" (by date of most current commit).

           Default value is "project". Unknown value means unsorted.

   Changing gitweb’s behavior
       These configuration variables control internal gitweb behavior.

       $default_blob_plain_mimetype
           Default mimetype for the blob_plain (raw) view, if mimetype checking doesn’t result in
           some other type; by default "text/plain". Gitweb guesses mimetype of a file to display
           based on extension of its filename, using $mimetypes_file (if set and file exists) and
           /etc/mime.types files (see mime.types(5) manpage; only filename extension rules are
           supported by gitweb).

       $default_text_plain_charset
           Default charset for text files. If this is not set, the web server configuration will
           be used. Unset by default.

       $fallback_encoding
           Gitweb assumes this charset when a line contains non-UTF-8 characters. The fallback
           decoding is used without error checking, so it can be even "utf-8". The value must be
           a valid encoding; see the Encoding::Supported(3pm) man page for a list. The default is
           "latin1", aka. "iso-8859-1".

       @diff_opts
           Rename detection options for git-diff and git-diff-tree. The default is ('-M'); set it
           to ('-C') or ('-C', '-C') to also detect copies, or set it to () i.e. empty list if
           you don’t want to have renames detection.

           Note that rename and especially copy detection can be quite CPU-intensive. Note also
           that non Git tools can have problems with patches generated with options mentioned
           above, especially when they involve file copies ('-C') or criss-cross renames ('-B').

   Some optional features and policies
       Most of features are configured via %feature hash; however some of extra gitweb features
       can be turned on and configured using variables described below. This list beside
       configuration variables that control how gitweb looks does contain variables configuring
       administrative side of gitweb (e.g. cross-site scripting prevention; admittedly this as
       side effect affects how "summary" pages look like, or load limiting).

       @git_base_url_list
           List of Git base URLs. These URLs are used to generate URLs describing from where to
           fetch a project, which are shown on project summary page. The full fetch URL is
           "$git_base_url/$project", for each element of this list. You can set up multiple base
           URLs (for example one for git:// protocol, and one for http:// protocol).

           Note that per repository configuration can be set in $GIT_DIR/cloneurl file, or as
           values of multi-value gitweb.url configuration variable in project config.
           Per-repository configuration takes precedence over value composed from
           @git_base_url_list elements and project name.

           You can setup one single value (single entry/item in this list) at build time by
           setting the GITWEB_BASE_URL build-time configuration variable. By default it is set to
           (), i.e. an empty list. This means that gitweb would not try to create project URL (to
           fetch) from project name.

       $projects_list_group_categories
           Whether to enable the grouping of projects by category on the project list page. The
           category of a project is determined by the $GIT_DIR/category file or the
           gitweb.category variable in each repository’s configuration. Disabled by default (set
           to 0).

       $project_list_default_category
           Default category for projects for which none is specified. If this is set to the empty
           string, such projects will remain uncategorized and listed at the top, above
           categorized projects. Used only if project categories are enabled, which means if
           $projects_list_group_categories is true. By default set to "" (empty string).

       $prevent_xss
           If true, some gitweb features are disabled to prevent content in repositories from
           launching cross-site scripting (XSS) attacks. Set this to true if you don’t trust the
           content of your repositories. False by default (set to 0).

       $maxload
           Used to set the maximum load that we will still respond to gitweb queries. If the
           server load exceeds this value then gitweb will return "503 Service Unavailable"
           error. The server load is taken to be 0 if gitweb cannot determine its value.
           Currently it works only on Linux, where it uses /proc/loadavg; the load there is the
           number of active tasks on the system — processes that are actually running — averaged
           over the last minute.

           Set $maxload to undefined value (undef) to turn this feature off. The default value is
           300.

       $omit_age_column
           If true, omit the column with date of the most current commit on the projects list
           page. It can save a bit of I/O and a fork per repository.

       $omit_owner
           If true prevents displaying information about repository owner.

       $per_request_config
           If this is set to code reference, it will be run once for each request. You can set
           parts of configuration that change per session this way. For example, one might use
           the following code in a gitweb configuration file

               our $per_request_config = sub {
                       $ENV{GL_USER} = $cgi->remote_user || "gitweb";
               };

           If $per_request_config is not a code reference, it is interpreted as boolean value. If
           it is true gitweb will process config files once per request, and if it is false
           gitweb will process config files only once, each time it is executed. True by default
           (set to 1).

           NOTE: $my_url, $my_uri, and $base_url are overwritten with their default values before
           every request, so if you want to change them, be sure to set this variable to true or
           a code reference effecting the desired changes.

           This variable matters only when using persistent web environments that serve multiple
           requests using single gitweb instance, like mod_perl, FastCGI or Plackup.

   Other variables
       Usually you should not need to change (adjust) any of configuration variables described
       below; they should be automatically set by gitweb to correct value.

       $version
           Gitweb version, set automatically when creating gitweb.cgi from gitweb.perl. You might
           want to modify it if you are running modified gitweb, for example

               our $version .= " with caching";

           if you run modified version of gitweb with caching support. This variable is purely
           informational, used e.g. in the "generator" meta header in HTML header.

       $my_url, $my_uri
           Full URL and absolute URL of the gitweb script; in earlier versions of gitweb you
           might have need to set those variables, but now there should be no need to do it. See
           $per_request_config if you need to set them still.

       $base_url
           Base URL for relative URLs in pages generated by gitweb, (e.g.  $logo, $favicon,
           @stylesheets if they are relative URLs), needed and used <base href="$base_url"> only
           for URLs with nonempty PATH_INFO. Usually gitweb sets its value correctly, and there
           is no need to set this variable, e.g. to $my_uri or "/". See $per_request_config if
           you need to override it anyway.

CONFIGURING GITWEB FEATURES

       Many gitweb features can be enabled (or disabled) and configured using the %feature hash.
       Names of gitweb features are keys of this hash.

       Each %feature hash element is a hash reference and has the following structure:

           "<feature_name>" => {
                   "sub" => <feature-sub (subroutine)>,
                   "override" => <allow-override (boolean)>,
                   "default" => [ <options>... ]
           },

       Some features cannot be overridden per project. For those features the structure of
       appropriate %feature hash element has a simpler form:

           "<feature_name>" => {
                   "override" => 0,
                   "default" => [ <options>... ]
           },

       As one can see it lacks the 'sub' element.

       The meaning of each part of feature configuration is described below:

       default
           List (array reference) of feature parameters (if there are any), used also to toggle
           (enable or disable) given feature.

           Note that it is currently always an array reference, even if feature doesn’t accept
           any configuration parameters, and 'default' is used only to turn it on or off. In such
           case you turn feature on by setting this element to [1], and torn it off by setting it
           to [0]. See also the passage about the "blame" feature in the "Examples" section.

           To disable features that accept parameters (are configurable), you need to set this
           element to empty list i.e.  [].

       override
           If this field has a true value then the given feature is overridable, which means that
           it can be configured (or enabled/disabled) on a per-repository basis.

           Usually given "<feature>" is configurable via the gitweb.<feature> config variable in
           the per-repository Git configuration file.

           Note that no feature is overridable by default.

       sub
           Internal detail of implementation. What is important is that if this field is not
           present then per-repository override for given feature is not supported.

           You wouldn’t need to ever change it in gitweb config file.

   Features in %feature
       The gitweb features that are configurable via %feature hash are listed below. This should
       be a complete list, but ultimately the authoritative and complete list is in gitweb.cgi
       source code, with features described in the comments.

       blame
           Enable the "blame" and "blame_incremental" blob views, showing for each line the last
           commit that modified it; see git-blame(1). This can be very CPU-intensive and is
           therefore disabled by default.

           This feature can be configured on a per-repository basis via repository’s gitweb.blame
           configuration variable (boolean).

       snapshot
           Enable and configure the "snapshot" action, which allows user to download a compressed
           archive of any tree or commit, as produced by git-archive(1) and possibly additionally
           compressed. This can potentially generate high traffic if you have large project.

           The value of 'default' is a list of names of snapshot formats, defined in
           %known_snapshot_formats hash, that you wish to offer. Supported formats include "tgz",
           "tbz2", "txz" (gzip/bzip2/xz compressed tar archive) and "zip"; please consult gitweb
           sources for a definitive list. By default only "tgz" is offered.

           This feature can be configured on a per-repository basis via repository’s gitweb.blame
           configuration variable, which contains a comma separated list of formats or "none" to
           disable snapshots. Unknown values are ignored.

       grep
           Enable grep search, which lists the files in currently selected tree (directory)
           containing the given string; see git-grep(1). This can be potentially CPU-intensive,
           of course. Enabled by default.

           This feature can be configured on a per-repository basis via repository’s gitweb.grep
           configuration variable (boolean).

       pickaxe
           Enable the so called pickaxe search, which will list the commits that introduced or
           removed a given string in a file. This can be practical and quite faster alternative
           to "blame" action, but it is still potentially CPU-intensive. Enabled by default.

           The pickaxe search is described in git-log(1) (the description of -S<string> option,
           which refers to pickaxe entry in gitdiffcore(7) for more details).

           This feature can be configured on a per-repository basis by setting repository’s
           gitweb.pickaxe configuration variable (boolean).

       show-sizes
           Enable showing size of blobs (ordinary files) in a "tree" view, in a separate column,
           similar to what ls -l does; see description of -l option in git-ls-tree(1) manpage.
           This costs a bit of I/O. Enabled by default.

           This feature can be configured on a per-repository basis via repository’s
           gitweb.showSizes configuration variable (boolean).

       patches
           Enable and configure "patches" view, which displays list of commits in email (plain
           text) output format; see also git-format-patch(1). The value is the maximum number of
           patches in a patchset generated in "patches" view. Set the default field to a list
           containing single item of or to an empty list to disable patch view, or to a list
           containing a single negative number to remove any limit. Default value is 16.

           This feature can be configured on a per-repository basis via repository’s
           gitweb.patches configuration variable (integer).

       avatar
           Avatar support. When this feature is enabled, views such as "shortlog" or "commit"
           will display an avatar associated with the email of each committer and author.

           Currently available providers are "gravatar" and "picon". Only one provider at a time
           can be selected (default is one element list). If an unknown provider is specified,
           the feature is disabled.  Note that some providers might require extra Perl packages
           to be installed; see gitweb/INSTALL for more details.

           This feature can be configured on a per-repository basis via repository’s
           gitweb.avatar configuration variable.

           See also %avatar_size with pixel sizes for icons and avatars ("default" is used for
           one-line like "log" and "shortlog", "double" is used for two-line like "commit",
           "commitdiff" or "tag"). If the default font sizes or lineheights are changed (e.g. via
           adding extra CSS stylesheet in @stylesheets), it may be appropriate to change these
           values.

       highlight
           Server-side syntax highlight support in "blob" view. It requires $highlight_bin
           program to be available (see the description of this variable in the "Configuration
           variables" section above), and therefore is disabled by default.

           This feature can be configured on a per-repository basis via repository’s
           gitweb.highlight configuration variable (boolean).

       remote_heads
           Enable displaying remote heads (remote-tracking branches) in the "heads" list. In most
           cases the list of remote-tracking branches is an unnecessary internal private detail,
           and this feature is therefore disabled by default.  git-instaweb(1), which is usually
           used to browse local repositories, enables and uses this feature.

           This feature can be configured on a per-repository basis via repository’s
           gitweb.remote_heads configuration variable (boolean).

       The remaining features cannot be overridden on a per project basis.

       search
           Enable text search, which will list the commits which match author, committer or
           commit text to a given string; see the description of --author, --committer and --grep
           options in git-log(1) manpage. Enabled by default.

           Project specific override is not supported.

       forks
           If this feature is enabled, gitweb considers projects in subdirectories of project
           root (basename) to be forks of existing projects. For each project $projname.git,
           projects in the $projname/ directory and its subdirectories will not be shown in the
           main projects list. Instead, a '+' mark is shown next to $projname, which links to a
           "forks" view that lists all the forks (all projects in $projname/ subdirectory).
           Additionally a "forks" view for a project is linked from project summary page.

           If the project list is taken from a file ($projects_list points to a file), forks are
           only recognized if they are listed after the main project in that file.

           Project specific override is not supported.

       actions
           Insert custom links to the action bar of all project pages. This allows you to link to
           third-party scripts integrating into gitweb.

           The "default" value consists of a list of triplets in the form ‘("<label>", "<link>",
           "<position>")` where "position" is the label after which to insert the link, "link" is
           a format string where %n expands to the project name, %f to the project path within
           the filesystem (i.e. "$projectroot/$project"), %h to the current hash ('h’ gitweb
           parameter) and ‘%b` to the current hash base ('hb’ gitweb parameter); ‘%%` expands to
           '%’.

           For example, at the time this page was written, the http://repo.or.cz Git hosting site
           set it to the following to enable graphical log (using the third party tool
           git-browser):

               $feature{'actions'}{'default'} =
                       [ ('graphiclog', '/git-browser/by-commit.html?r=%n', 'summary')];

           This adds a link titled "graphiclog" after the "summary" link, leading to git-browser
           script, passing r=<project> as a query parameter.

           Project specific override is not supported.

       timed
           Enable displaying how much time and how many Git commands it took to generate and
           display each page in the page footer (at the bottom of page). For example the footer
           might contain: "This page took 6.53325 seconds and 13 Git commands to generate."
           Disabled by default.

           Project specific override is not supported.

       javascript-timezone
           Enable and configure the ability to change a common time zone for dates in gitweb
           output via JavaScript. Dates in gitweb output include authordate and committerdate in
           "commit", "commitdiff" and "log" views, and taggerdate in "tag" view. Enabled by
           default.

           The value is a list of three values: a default time zone (for if the client hasn’t
           selected some other time zone and saved it in a cookie), a name of cookie where to
           store selected time zone, and a CSS class used to mark up dates for manipulation. If
           you want to turn this feature off, set "default" to empty list: [].

           Typical gitweb config files will only change starting (default) time zone, and leave
           other elements at their default values:

               $feature{'javascript-timezone'}{'default'}[0] = "utc";

           The example configuration presented here is guaranteed to be backwards and forward
           compatible.

           Time zone values can be "local" (for local time zone that browser uses), "utc" (what
           gitweb uses when JavaScript or this feature is disabled), or numerical time zones in
           the form of "+/-HHMM", such as "+0200".

           Project specific override is not supported.

       extra-branch-refs
           List of additional directories under "refs" which are going to be used as branch refs.
           For example if you have a gerrit setup where all branches under refs/heads/ are
           official, push-after-review ones and branches under refs/sandbox/, refs/wip and
           refs/other are user ones where permissions are much wider, then you might want to set
           this variable as follows:

               $feature{'extra-branch-refs'}{'default'} =
                       ['sandbox', 'wip', 'other'];

           This feature can be configured on per-repository basis after setting
           $feature{extra-branch-refs}{override} to true, via repository’s gitweb.extraBranchRefs
           configuration variable, which contains a space separated list of refs. An example:

               [gitweb]
                       extraBranchRefs = sandbox wip other

           The gitweb.extraBranchRefs is actually a multi-valued configuration variable, so
           following example is also correct and the result is the same as of the snippet above:

               [gitweb]
                       extraBranchRefs = sandbox
                       extraBranchRefs = wip other

           It is an error to specify a ref that does not pass "git check-ref-format" scrutiny.
           Duplicated values are filtered.

EXAMPLES

       To enable blame, pickaxe search, and snapshot support (allowing "tar.gz" and "zip"
       snapshots), while allowing individual projects to turn them off, put the following in your
       GITWEB_CONFIG file:

           $feature{'blame'}{'default'} = [1];
           $feature{'blame'}{'override'} = 1;

           $feature{'pickaxe'}{'default'} = [1];
           $feature{'pickaxe'}{'override'} = 1;

           $feature{'snapshot'}{'default'} = ['zip', 'tgz'];
           $feature{'snapshot'}{'override'} = 1;

       If you allow overriding for the snapshot feature, you can specify which snapshot formats
       are globally disabled. You can also add any command-line options you want (such as setting
       the compression level). For instance, you can disable Zip compressed snapshots and set
       gzip(1) to run at level 6 by adding the following lines to your gitweb configuration file:

           $known_snapshot_formats{'zip'}{'disabled'} = 1;
           $known_snapshot_formats{'tgz'}{'compressor'} = ['gzip','-6'];

BUGS

       Debugging would be easier if the fallback configuration file (/etc/gitweb.conf) and
       environment variable to override its location (GITWEB_CONFIG_SYSTEM) had names reflecting
       their "fallback" role. The current names are kept to avoid breaking working setups.

ENVIRONMENT

       The location of per-instance and system-wide configuration files can be overridden using
       the following environment variables:

       GITWEB_CONFIG
           Sets location of per-instance configuration file.

       GITWEB_CONFIG_SYSTEM
           Sets location of fallback system-wide configuration file. This file is read only if
           per-instance one does not exist.

       GITWEB_CONFIG_COMMON
           Sets location of common system-wide configuration file.

FILES

       gitweb_config.perl
           This is default name of per-instance configuration file. The format of this file is
           described above.

       /etc/gitweb.conf
           This is default name of fallback system-wide configuration file. This file is used
           only if per-instance configuration variable is not found.

       /etc/gitweb-common.conf
           This is default name of common system-wide configuration file.
