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
instead
$ 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
scripts).
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 affects building of
gitweb.cgi; see "default configuration for gitweb" section in main
(top dir) Makefile, and instructions for building gitweb/gitweb.cgi
target.
One of most important is where to find git wrapper binary. Gitweb
tries to find 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 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)
accordingly.
- Another important issue is where are git repositories you want to make
available to gitweb. By default gitweb search 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. 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
below.
Note that gitweb deals directly with object database, and does not
need 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)
repository, you can make projectname.git 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 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 \
gitweb/gitweb.cgi
cp -fv ~/git/gitweb/gitweb.{cgi,css} \
~/git/gitweb/git-{favicon,logo}.png \
/var/www/cgi-bin/gitweb/
Gitweb config file
------------------
See also "Runtime gitweb configuration" section in README file
for gitweb (in gitweb/README).
- You can configure gitweb further using gitweb configuration file;
by default it is file named gitweb_config.perl in the same place as
gitweb.cgi script. You can control default place for config file
using GITWEB_CONFIG build configuration variable, and you can set it
using GITWEB_CONFIG environmental 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 GITWEB_CONFIG_SYSTEM environmental variable.
- Gitweb config file is [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
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;
Gitweb repositories
-------------------
- By default all git repositories under projectroot are visible and
available to gitweb. 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 pre-generated list of [visible] repositories,
together with information about their owners (the project ownership
is taken from owner of repository directory otherwise), by setting
GITWEB_LIST build configuration variable (or $projects_list variable
in gitweb config file) to point to a plain file.
Each line of projects list file should consist of url-encoded path
to project repository database (relative to projectroot) separated
by space from url-encoded project owner; spaces in both project path
and project owner have to be encoded as either '%20' or '+'.
You can generate projects list index file using project_index action
(the 'TXT' link on projects list page) directly from gitweb.
- By default even if project is not visible on projects list page, you
can view it nevertheless by hand-crafting gitweb URL. You can set
GITWEB_STRICT_EXPORT build configuration variable (or $strict_export
variable in 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
GITWEB_EXPORT_OK build configuration variable (or $export_ok
variable in gitweb config file). If it evaluates to true, gitweb
show repository only if this file exists in its object database
(if directory has the magic file $export_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
Requirements
------------
- Core git tools
