GIT web Interface (gitweb) Installation
First you have to generate gitweb.cgi from gitweb.perl using
"make gitweb/gitweb.cgi", then copy appropriate files (gitweb.cgi,
gitweb.css, git-logo.png and git-favicon.png) to their destination.
For example if git was (or is) installed with /usr prefix, you can do
$ make prefix=/usr gitweb/gitweb.cgi ;# as yourself
# cp gitweb/git* /var/www/cgi-bin/ ;# as root
Alternatively you can use autoconf generated ./configure script to
set up path to git binaries (via config.mak.autogen), so you can write
$ make configure ;# as yourself
$ ./configure --prefix=/usr ;# as yourself
$ make gitweb/gitweb.cgi ;# as yourself
# cp gitweb/git* /var/www/cgi-bin/ ;# as root
The above example assumes that your web server is configured to run
[executable] files in /var/www/cgi-bin/ as server scripts (as CGI
Build time configuration
See also "How to configure gitweb for your local system" in README
file for gitweb (in gitweb/README).
- There are many configuration variables which affect building of
gitweb.cgi; see "default configuration for gitweb" section in main
(top dir) Makefile, and instructions for building gitweb/gitweb.cgi
One of the most important is where to find the git wrapper binary. Gitweb
tries to find the git wrapper at $(bindir)/git, so you have to set $bindir
when building gitweb.cgi, or $prefix from which $bindir is derived. If
you build and install gitweb together with the rest of the git suite,
there should be no problems. Otherwise, if git was for example
installed from a binary package, you have to set $prefix (or $bindir)
- Another important issue is where are git repositories you want to make
available to gitweb. By default gitweb searches for repositories under
/pub/git; if you want to have projects somewhere else, like /home/git,
use GITWEB_PROJECTROOT build configuration variable.
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. This can be
changed (configured) as described in "Gitweb repositories" section
Note that gitweb deals directly with the object database, and does not
need a working directory; the name of the project is the name of its
repository object database, usually projectname.git for bare
repositories. If you want to provide gitweb access to non-bare (live)
repositories, you can make projectname.git a symbolic link under
projectroot linking to projectname/.git (but it is just
a suggestion).
- You can control where gitweb tries to find its main CSS style file,
its favicon and logo with the GITWEB_CSS, GITWEB_FAVICON and GITWEB_LOGO
build configuration variables. By default gitweb tries to find them
in the same directory as gitweb.cgi script.
Build example
- To install gitweb to /var/www/cgi-bin/gitweb/ when git wrapper
is installed at /usr/local/bin/git and the repositories (projects)
we want to display are under /home/local/scm, you can do
make GITWEB_PROJECTROOT="/home/local/scm" \
GITWEB_CSS="/gitweb/gitweb.css" \
GITWEB_LOGO="/gitweb/git-logo.png" \
GITWEB_FAVICON="/gitweb/git-favicon.png" \
bindir=/usr/local/bin \
cp -fv ~/git/gitweb/gitweb.{cgi,css} \
~/git/gitweb/git-{favicon,logo}.png \
Gitweb config file
See also "Runtime gitweb configuration" section in README file
for gitweb (in gitweb/README).
- You can configure gitweb further using the 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
using the GITWEB_CONFIG environment variable. If this file does not
exist, gitweb looks for a system-wide configuration file, normally
/etc/gitweb.conf. You can change the default using the
GITWEB_CONFIG_SYSTEM build configuration variable, and override it
through the GITWEB_CONFIG_SYSTEM environment variable.
- 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.
See the top of gitweb.perl file for examples of customizable options.
Config file example
To enable blame, pickaxe search, and snapshot support, while allowing
individual projects to turn them off, put the following in your
$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;
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
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";
$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):
export GITWEB_CONFIG="gitweb_make_index.perl"
export HTTP_ACCEPT="*/*"
export QUERY_STRING="a=project_index"
