Build time configuration
------------------------
-See also "How to configure gitweb for your local system" in README
-file for gitweb (in gitweb/README).
+See also "How to configure gitweb for your local system" section below.
- There are many configuration variables which affect building of
gitweb.cgi; see "default configuration for gitweb" section in main
substitute gitweb.min.js and gitweb.min.css for all uses of gitweb.js and
gitweb.css in the help files.
+
+How to configure gitweb for your local system
+---------------------------------------------
+
+You can specify the following configuration variables when building GIT:
+
+ * GIT_BINDIR
+ Points where to find the git executable. You should set it up to
+ the place where the git binary was installed (usually /usr/bin) if you
+ don't install git from sources together with gitweb. [Default: $(bindir)]
+ * GITWEB_SITENAME
+ Shown in the title of all generated pages, defaults to the server name
+ (SERVER_NAME CGI environment variable) if not set. [No default]
+ * GITWEB_PROJECTROOT
+ The root directory for all projects shown by gitweb. Must be set
+ correctly for gitweb to find repositories to display. See also
+ "Gitweb repositories" in the INSTALL file for gitweb. [Default: /pub/git]
+ * GITWEB_PROJECT_MAXDEPTH
+ The filesystem traversing limit for getting the project list; the number
+ is taken as depth relative to the projectroot. It is used when
+ GITWEB_LIST is a directory (or is not set; then project root is used).
+ This is meant to speed up project listing on large work trees by limiting
+ search depth. [Default: 2007]
+ * GITWEB_LIST
+ Points to a directory to scan for projects (defaults to project root
+ if not set / if empty) or to a file with explicit listing of projects
+ (together with projects' ownership). See "Generating projects list
+ using gitweb" in INSTALL file for gitweb to find out how to generate
+ such file from scan of a directory. [No default, which means use root
+ directory for projects]
+ * GITWEB_EXPORT_OK
+ Show repository only if this file exists (in repository). Only
+ effective if this variable evaluates to true. [No default / Not set]
+ * GITWEB_STRICT_EXPORT
+ Only allow viewing of repositories also shown on the overview page.
+ This for example makes GITWEB_EXPORT_OK to 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. [No default]
+ * GITWEB_HOMETEXT
+ Points to an .html file which is included on the gitweb project
+ overview page ('projects_list' view), if it exists. Relative to
+ gitweb.cgi script. [Default: indextext.html]
+ * GITWEB_SITE_HTML_HEAD_STRING
+ html snippet to include in the <head> section of each page. [No default]
+ * GITWEB_SITE_HEADER
+ Filename of html text to include at top of each page. Relative to
+ gitweb.cgi script. [No default]
+ * GITWEB_SITE_FOOTER
+ Filename of html text to include at bottom of each page. Relative to
+ gitweb.cgi script. [No default]
+ * GITWEB_HOME_LINK_STR
+ String of the home link on top of all pages, leading to $home_link
+ (usually main gitweb page, which means projects list). Used as first
+ part of gitweb view "breadcrumb trail": <home> / <project> / <view>.
+ [Default: projects]
+ * GITWEB_SITENAME
+ Name of your site or organization to appear in page titles. Set it
+ to something descriptive for clearer bookmarks etc. If not set
+ (if empty) gitweb uses "$SERVER_NAME Git", or "Untitled Git" if
+ SERVER_NAME CGI environment variable is not set (e.g. if running
+ gitweb as standalone script). [No default]
+ * GITWEB_BASE_URL
+ Git base URLs used for URL to where fetch project from, i.e. full
+ URL is "$git_base_url/$project". Shown on projects summary page.
+ Repository URL for project can be also configured per repository; this
+ takes precedence over URLs composed from base URL and a project name.
+ Note that you can setup multiple base URLs (for example one for
+ git:// protocol access, another for http:// access) from the gitweb
+ config file. [No default]
+ * GITWEB_CSS
+ Points to the location where you put gitweb.css on your web server
+ (or to be more generic, the URI of gitweb stylesheet). Relative to the
+ base URI of gitweb. Note that you can setup multiple stylesheets from
+ the gitweb config file. [Default: static/gitweb.css (or
+ static/gitweb.min.css if the CSSMIN variable is defined / CSS minifier
+ is used)]
+ * GITWEB_JS
+ Points to the location where you put gitweb.js on your web server
+ (or to be more generic URI of JavaScript code used by gitweb).
+ Relative to base URI of gitweb. [Default: static/gitweb.js (or
+ static/gitweb.min.js if JSMIN build variable is defined / JavaScript
+ minifier is used)]
+ * CSSMIN, JSMIN
+ Invocation of a CSS minifier or a JavaScript minifier, respectively,
+ working as a filter (source on standard input, minified result on
+ standard output). If set, it is used to generate a minified version of
+ 'static/gitweb.css' or 'static/gitweb.js', respectively. *Note* that
+ minified files would have *.min.css and *.min.js extension, which is
+ important if you also set GITWEB_CSS and/or GITWEB_JS. [No default]
+ * GITWEB_LOGO
+ Points to the location where you put git-logo.png on your web server
+ (or to be more generic URI of logo, 72x27 size, displayed in top right
+ corner of each gitweb page, and used as logo for Atom feed). Relative
+ to base URI of gitweb. [Default: static/git-logo.png]
+ * GITWEB_FAVICON
+ Points to the location where you put git-favicon.png on your web server
+ (or to be more generic URI of favicon, assumed to be image/png type;
+ web browsers that support favicons (website icons) may display them
+ in the browser's URL bar and next to site name in bookmarks). Relative
+ to base URI of gitweb. [Default: static/git-favicon.png]
+ * GITWEB_CONFIG
+ This Perl file will be loaded using 'do' and can be used to override any
+ of the options above as well as some other options -- see the "Runtime
+ gitweb configuration" section below, and top of 'gitweb.cgi' for their
+ full list and description. If the environment variable GITWEB_CONFIG
+ is set when gitweb.cgi is executed, then the file specified in the
+ environment variable will be loaded instead of the file specified
+ when gitweb.cgi was created. [Default: gitweb_config.perl]
+ * GITWEB_CONFIG_SYSTEM
+ This Perl file will be loaded using 'do' as a fallback if GITWEB_CONFIG
+ does not exist. If the environment variable GITWEB_CONFIG_SYSTEM is set
+ when gitweb.cgi is executed, then the file specified in the environment
+ variable will be loaded instead of the file specified when gitweb.cgi was
+ created. [Default: /etc/gitweb.conf]
+ * HIGHLIGHT_BIN
+ Path to the highlight executable to use (must be the one from
+ http://www.andre-simon.de due to assumptions about parameters and output).
+ Useful if highlight is not installed on your webserver's PATH.
+ [Default: highlight]
+

-- You can configure gitweb further using the gitweb configuration file;
+- You can configure gitweb further using the per-instance gitweb configuration file;
by default this is a file named gitweb_config.perl in the same place as
gitweb.cgi script. You can control the default place for the config file
using the GITWEB_CONFIG build configuration variable, and you can set it
GITWEB_CONFIG_SYSTEM build configuration variable, and override it
through the GITWEB_CONFIG_SYSTEM environment variable.
+ Note that if per-instance configuration file exists, then system-wide
+ configuration is _not used at all_. This is quite untypical and suprising
+ behavior. On the other hand changing current behavior would break backwards
+ compatibility and can lead to unexpected changes in gitweb behavior.
+ Therefore gitweb also looks for common system-wide configuration file,
+ normally /etc/gitweb-common.conf (set during build time using build time
+ configuration variable GITWEB_CONFIG_COMMON, set it at runtime using
+ environment variable with the same name). Settings from per-instance or
+ system-wide configuration file override those from common system-wide
+ configuration file.
+
- The gitweb config file is a fragment of perl code. You can set variables
using "our $variable = value"; text from "#" character until the end
of a line is ignored. See perlsyn(1) for details.
Gitweb repositories
-------------------
-- By default all git repositories under projectroot are visible and
- available to gitweb. The list of projects is generated by default by
- scanning the projectroot directory for git repositories (for object
- databases to be more exact).
-
- You can provide a pre-generated list of [visible] repositories,
- together with information about their owners (the project ownership
- defaults to the owner of the repository directory otherwise), by setting
- the GITWEB_LIST build configuration variable (or the $projects_list
- variable in the gitweb config file) to point to a plain file.
-
- Each line of the projects list file should consist of the url-encoded path
- to the project repository database (relative to projectroot), followed
- by the url-encoded project owner on the same line (separated by a space).
- Spaces in both project path and project owner have to be encoded as either
- '%20' or '+'.
-
- Other characters that have to be url-encoded, i.e. replaced by '%'
- followed by two-digit character number in octal, are: other whitespace
- characters (because they are field separator in a record), plus sign '+'
- (because it can be used as replacement for spaces), and percent sign '%'
- (which is used for encoding / escaping).
-
- You can generate the projects list index file using the project_index
- action (the 'TXT' link on projects list page) directly from gitweb.
-
-- By default, even if a project is not visible on projects list page, you
- can view it nevertheless by hand-crafting a gitweb URL. You can set the
- GITWEB_STRICT_EXPORT build configuration variable (or the $strict_export
- variable in the gitweb config file) to only allow viewing of
- repositories also shown on the overview page.
-
-- Alternatively, you can configure gitweb to only list and allow
- viewing of the explicitly exported repositories, via the
- GITWEB_EXPORT_OK build configuration variable (or the $export_ok
- variable in gitweb config file). If it evaluates to true, gitweb
- shows repositories only if this file exists in its object database
- (if directory has the magic file named $export_ok).
-
-- Finally, it is possible to specify an arbitrary perl subroutine that
- will be called for each project to determine if it can be exported.
- The subroutine receives an absolute path to the project as its only
- parameter.
-
- For example, if you use mod_perl to run the script, and have dumb
- http protocol authentication configured for your repositories, you
- can use the following hook to allow access only if the user is
- authorized to read the files:
-
- $export_auth_hook = sub {
- use Apache2::SubRequest ();
- use Apache2::Const -compile => qw(HTTP_OK);
- my $path = "$_[0]/HEAD";
- my $r = Apache2::RequestUtil->request;
- my $sub = $r->lookup_file($path);
- return $sub->filename eq $path
- && $sub->status == Apache2::Const::HTTP_OK;
- };
-
-
-Generating projects list using gitweb
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-We assume that GITWEB_CONFIG has its default Makefile value, namely
-gitweb_config.perl. Put the following in gitweb_make_index.perl file:
-
- $GITWEB_CONFIG = "gitweb_config.perl";
- do $GITWEB_CONFIG if -e $GITWEB_CONFIG;
-
- $projects_list = $projectroot;
-
-Then create the following script to get list of project in the format
-suitable for GITWEB_LIST build configuration variable (or
-$projects_list variable in gitweb config):
-
- #!/bin/sh
-
- export GITWEB_CONFIG="gitweb_make_index.perl"
- export GATEWAY_INTERFACE="CGI/1.1"
- export HTTP_ACCEPT="*/*"
- export REQUEST_METHOD="GET"
- export QUERY_STRING="a=project_index"
-
- perl -- /var/www/cgi-bin/gitweb.cgi
-
