GIT web Interface (gitweb) Installation
=======================================
First you have to generate gitweb.cgi from gitweb.perl using
"make gitweb", then "make install-gitweb" appropriate files
(gitweb.cgi, gitweb.js, gitweb.css, git-logo.png and git-favicon.png)
to their destination. For example if git was (or is) installed with
/usr prefix and gitwebdir is /var/www/cgi-bin, you can do
$ make prefix=/usr gitweb ;# as yourself
# make gitwebdir=/var/www/cgi-bin install-gitweb ;# 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 ;# as yourself
# make gitwebdir=/var/www/cgi-bin \
install-gitweb ;# 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).
Requirements
------------
- Core git tools
- Perl 5.8
- Perl modules: CGI, Encode, Fcntl, File::Find, File::Basename.
- web server
The following optional Perl modules are required for extra features
- CGI::Fast and FCGI - for running gitweb as FastCGI script
- HTML::TagCloud - for fancy tag cloud in project list view
- HTTP::Date or Time::ParseDate - to support If-Modified-Since for feeds
Build time configuration
------------------------
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
(top dir) Makefile, and instructions for building gitweb target.
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)
accordingly.
- 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
below.
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 JavaScript file, its favicon and logo with the GITWEB_CSS, GITWEB_JS
GITWEB_FAVICON and GITWEB_LOGO build configuration variables. By default
gitweb tries to find them in the same directory as gitweb.cgi script.
- You can optionally generate minified versions of gitweb.js and gitweb.css
by defining the JSMIN and CSSMIN build configuration variables. By default
the non-minified versions will be used. NOTE: if you enable this option,
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]
Build example
~~~~~~~~~~~~~
- To install gitweb to /var/www/cgi-bin/gitweb/, when git wrapper
is installed at /usr/local/bin/git, the repositories (projects)
we want to display are under /home/local/scm, and you do not use
minifiers, you can do
make GITWEB_PROJECTROOT="/home/local/scm" \
GITWEB_JS="gitweb/static/gitweb.js" \
GITWEB_CSS="gitweb/static/gitweb.css" \
GITWEB_LOGO="gitweb/static/git-logo.png" \
GITWEB_FAVICON="gitweb/static/git-favicon.png" \
bindir=/usr/local/bin \
gitweb
make gitwebdir=/var/www/cgi-bin/gitweb install-gitweb
Gitweb config file
------------------
See also "Runtime gitweb configuration" section in README file
for gitweb (in gitweb/README), and gitweb.conf(5) manpage.
- 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
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.
Note that the GITWEB_CONFIG_SYSTEM system-wide configuration file is
only used for instances that lack per-instance configuration file.
You can use GITWEB_CONFIG_COMMON common system-wide configuration
file (normally /etc/gitweb-common.conf) to keep common default
settings that apply to all instances. 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.
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;
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 to run at level 6 by
adding the following lines to your $GITWEB_CONFIG:
$known_snapshot_formats{'zip'}{'disabled'} = 1;
$known_snapshot_formats{'tgz'}{'compressor'} = ['gzip','-6'];
Gitweb repositories
-------------------
By default gitweb shows all git repositories under single common repository
root on a local filesystem; see description of GITWEB_PROJECTROOT build-time
configuration variable above (and also of GITWEB_LIST).
More advanced usage, like limiting access or visibility of repositories and
managing multiple roots are described on gitweb manpage.
