Cgit is an attempt to create a fast web interface for the git scm, using a builtin cache to decrease server io-pressure.

Installation

Installing cgit is rather simple as it's available in the Community repository:

# pacman -S cgit

In order to actually use cgit you will of course also need to have some webserver installed on your system, like for example Apache.

Configuration of Web Server

Apache

You may add the following either to the end of your /etc/httpd/conf/httpd.conf file or place it in a separate file inside the /etc/httpd/conf/extra/ directory.

#
# cgit configuration for apache
#

ScriptAlias /cgit/ "/usr/lib/cgit/cgit.cgi/"
Alias /cgit-css "/usr/share/webapps/cgit/"
<Directory "/usr/share/webapps/cgit/">
   AllowOverride None
   Options None
   Order allow,deny
   Allow from all
</Directory>
<Directory "/usr/lib/cgit/">
   AllowOverride None
   Options ExecCGI FollowSymlinks
   Order allow,deny
   Allow from all
</Directory>

Lighttpd

Information for Lighttpd and cgit is scarse... The following configuration will let you access cgit through http://your.server.com/cgit with http://your.server.com/git redirecting to it. It's not perfect (for example you'll see "cgit.cgi" in all repos' url) but works.

Create the file /etc/lighttpd/conf.d/cgit.conf:

server.modules += ("mod_redirect",
                  "mod_alias",
                  "mod_cgi",
                  "mod_fastcgi",
                  "mod_rewrite" )
var.webapps  = "/usr/share/webapps/"
$HTTP["url"] =~ "^/cgit" {
    server.document-root = webapps
    server.indexfiles = ("cgit.cgi")
    cgi.assign = ("cgit.cgi" => "")
    mimetype.assign = ( ".css" => "text/css" )
}
url.redirect = (
    "^/git/(.*)$" => "/cgit/cgit.cgi/$1",
)

Just include this file in /etc/lighttpd/lighttpd.conf:

include "conf.d/cgit.conf"

and restart lighttpd.

Configuration of Cgit

Basic Configuration

Before you can start adding repositories you will first have to create the basic cgit configuration file at /etc/cgitrc.

#
# cgit config
#

css=/cgit-css/cgit.css
logo=/cgit-css/cgit.png

# if you don't want that webcrawler (like google) index your site
robots=noindex, nofollow

Adding repositories

Now you can add your repos:

#
# List of repositories.
# This list could be kept in a different file (e.g. '/etc/cgitrepos')
# and included like this:
#   include=/etc/cgitrepos
#

repo.url=MyRepo
repo.path=/srv/git/MyRepo.git
repo.desc=This is my git repository

repo.url=MyOtherRepo
repo.path=/srv/git/MyOtherRepo.git
repo.desc=That's my other git repository

If you prefer not having to manually specify each repository it's also possible to configure cgit to search for them:

scan-path=/srv/git/

For detailed documentation about the available settings in this configuration file, please see the manage (`man cgitrc`).

Syntax highlighting

Cgit supports syntax highlighting when viewing blobs. To enable syntax highlighting, you have to install the highlight package.

# pacman -S highlight

Edit /usr/lib/cgit/filters/syntax-highlighting.sh. Comment out version 2 and comment in version 3. You may want to add --inline-css to the options of highlight for a more colorfull output without editing cgit's css file.

 # This is for version 2
 #exec highlight --force -f -I -X -S "$EXTENSION" 2>/dev/null
 
 # This is for version 3
 exec highlight --force --inline-css -f -I -O xhtml -S "$EXTENSION" 2>/dev/null

Enable the filter in /etc/cgitrc

source-filter=/usr/lib/cgit/filters/syntax-highlighting.sh

Integration

Gitosis

If you want to integrate with gitosis you will have to run two commands to give apache permission to look though the folder.

# chgrp http /srv/gitosis
# chmod a+rx /srv/gitosis

Gitolite

If you added repositories managed by gitolite you have to change the permissions, so the web server can access the files.

  • Change permission for future repositories:
  • Change permission for existing repositories:
    • Run the following two commands (as root or gitolite-user):
      • # find /path/to/the/repository/ -type d -exec chmod og+rx {} \;
      • # find /path/to/the/repository/ -type f -exec chmod og+r {} \;
