1 GIT web Interface (gitweb) Installation
2 =======================================
4 First you have to generate gitweb.cgi from gitweb.perl using
5 "make gitweb/gitweb.cgi", then copy appropriate files (gitweb.cgi,
6 gitweb.css, git-logo.png and git-favicon.png) to their destination.
7 For example if git was (or is) installed with /usr prefix, you can do
9 $ make prefix=/usr gitweb/gitweb.cgi ;# as yourself
10 # cp gitweb/git* /var/www/cgi-bin/ ;# as root
12 Alternatively you can use autoconf generated ./configure script to
13 set up path to git binaries (via config.mak.autogen), so you can write
16 $ make configure ;# as yourself
17 $ ./configure --prefix=/usr ;# as yourself
18 $ make gitweb/gitweb.cgi ;# as yourself
19 # cp gitweb/git* /var/www/cgi-bin/ ;# as root
21 The above example assumes that your web server is configured to run
22 [executable] files in /var/www/cgi-bin/ as server scripts (as CGI
26 Build time configuration
27 ------------------------
29 See also "How to configure gitweb for your local system" in README
30 file for gitweb (in gitweb/README).
32 - There are many configuration variables which affect building of
33 gitweb.cgi; see "default configuration for gitweb" section in main
34 (top dir) Makefile, and instructions for building gitweb/gitweb.cgi
37 One of the most important is where to find the git wrapper binary. Gitweb
38 tries to find the git wrapper at $(bindir)/git, so you have to set $bindir
39 when building gitweb.cgi, or $prefix from which $bindir is derived. If
40 you build and install gitweb together with the rest of the git suite,
41 there should be no problems. Otherwise, if git was for example
42 installed from a binary package, you have to set $prefix (or $bindir)
45 - Another important issue is where are git repositories you want to make
46 available to gitweb. By default gitweb searches for repositories under
47 /pub/git; if you want to have projects somewhere else, like /home/git,
48 use GITWEB_PROJECTROOT build configuration variable.
50 By default all git repositories under projectroot are visible and
51 available to gitweb. The list of projects is generated by default by
52 scanning the projectroot directory for git repositories. This can be
53 changed (configured) as described in "Gitweb repositories" section
56 Note that gitweb deals directly with the object database, and does not
57 need a working directory; the name of the project is the name of its
58 repository object database, usually projectname.git for bare
59 repositories. If you want to provide gitweb access to non-bare (live)
60 repositories, you can make projectname.git a symbolic link under
61 projectroot linking to projectname/.git (but it is just
64 - You can control where gitweb tries to find its main CSS style file,
65 its favicon and logo with the GITWEB_CSS, GITWEB_FAVICON and GITWEB_LOGO
66 build configuration variables. By default gitweb tries to find them
67 in the same directory as gitweb.cgi script.
72 - To install gitweb to /var/www/cgi-bin/gitweb/ when git wrapper
73 is installed at /usr/local/bin/git and the repositories (projects)
74 we want to display are under /home/local/scm, you can do
76 make GITWEB_PROJECTROOT="/home/local/scm" \
77 GITWEB_CSS="/gitweb/gitweb.css" \
78 GITWEB_LOGO="/gitweb/git-logo.png" \
79 GITWEB_FAVICON="/gitweb/git-favicon.png" \
80 bindir=/usr/local/bin \
83 cp -fv ~/git/gitweb/gitweb.{cgi,css} \
84 ~/git/gitweb/git-{favicon,logo}.png \
85 /var/www/cgi-bin/gitweb/
91 See also "Runtime gitweb configuration" section in README file
92 for gitweb (in gitweb/README).
94 - You can configure gitweb further using the gitweb configuration file;
95 by default this is a file named gitweb_config.perl in the same place as
96 gitweb.cgi script. You can control the default place for the config file
97 using the GITWEB_CONFIG build configuration variable, and you can set it
98 using the GITWEB_CONFIG environment variable. If this file does not
99 exist, gitweb looks for a system-wide configuration file, normally
100 /etc/gitweb.conf. You can change the default using the
101 GITWEB_CONFIG_SYSTEM build configuration variable, and override it
102 through the GITWEB_CONFIG_SYSTEM environment variable.
104 - The gitweb config file is a fragment of perl code. You can set variables
105 using "our $variable = value"; text from "#" character until the end
106 of a line is ignored. See perlsyn(1) for details.
108 See the top of gitweb.perl file for examples of customizable options.
113 To enable blame, pickaxe search, and snapshot support, while allowing
114 individual projects to turn them off, put the following in your
117 $feature{'blame'}{'default'} = [1];
118 $feature{'blame'}{'override'} = 1;
120 $feature{'pickaxe'}{'default'} = [1];
121 $feature{'pickaxe'}{'override'} = 1;
123 $feature{'snapshot'}{'default'} = ['zip', 'tgz'];
124 $feature{'snapshot'}{'override'} = 1;
126 If you allow overriding for the snapshot feature, you can specify which
127 snapshot formats are globally disabled. You can also add any command line
128 options you want (such as setting the compression level). For instance,
129 you can disable Zip compressed snapshots and set GZip to run at level 6 by
130 adding the following lines to your $GITWEB_CONFIG:
132 $known_snapshot_formats{'zip'}{'disabled'} = 1;
133 $known_snapshot_formats{'tgz'}{'compressor'} = ['gzip','-6'];
139 - By default all git repositories under projectroot are visible and
140 available to gitweb. The list of projects is generated by default by
141 scanning the projectroot directory for git repositories (for object
142 databases to be more exact).
144 You can provide a pre-generated list of [visible] repositories,
145 together with information about their owners (the project ownership
146 defaults to the owner of the repository directory otherwise), by setting
147 the GITWEB_LIST build configuration variable (or the $projects_list
148 variable in the gitweb config file) to point to a plain file.
150 Each line of the projects list file should consist of the url-encoded path
151 to the project repository database (relative to projectroot), followed
152 by the url-encoded project owner on the same line (separated by a space).
153 Spaces in both project path and project owner have to be encoded as either
156 Other characters that have to be url-encoded, i.e. replaced by '%'
157 followed by two-digit character number in octal, are: other whitespace
158 characters (because they are field separator in a record), plus sign '+'
159 (because it can be used as replacement for spaces), and percent sign '%'
160 (which is used for encoding / escaping).
162 You can generate the projects list index file using the project_index
163 action (the 'TXT' link on projects list page) directly from gitweb.
165 - By default, even if a project is not visible on projects list page, you
166 can view it nevertheless by hand-crafting a gitweb URL. You can set the
167 GITWEB_STRICT_EXPORT build configuration variable (or the $strict_export
168 variable in the gitweb config file) to only allow viewing of
169 repositories also shown on the overview page.
171 - Alternatively, you can configure gitweb to only list and allow
172 viewing of the explicitly exported repositories, via the
173 GITWEB_EXPORT_OK build configuration variable (or the $export_ok
174 variable in gitweb config file). If it evaluates to true, gitweb
175 shows repositories only if this file exists in its object database
176 (if directory has the magic file named $export_ok).
178 - Finally, it is possible to specify an arbitrary perl subroutine that
179 will be called for each project to determine if it can be exported.
180 The subroutine receives an absolute path to the project as its only
183 For example, if you use mod_perl to run the script, and have dumb
184 http protocol authentication configured for your repositories, you
185 can use the following hook to allow access only if the user is
186 authorized to read the files:
188 $export_auth_hook = sub {
189 use Apache2::SubRequest ();
190 use Apache2::Const -compile => qw(HTTP_OK);
191 my $path = "$_[0]/HEAD";
192 my $r = Apache2::RequestUtil->request;
193 my $sub = $r->lookup_file($path);
194 return $sub->filename eq $path
195 && $sub->status == Apache2::Const::HTTP_OK;
199 Generating projects list using gitweb
200 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
202 We assume that GITWEB_CONFIG has its default Makefile value, namely
203 gitweb_config.perl. Put the following in gitweb_make_index.perl file:
205 $GITWEB_CONFIG = "gitweb_config.perl";
206 do $GITWEB_CONFIG if -e $GITWEB_CONFIG;
208 $projects_list = $projectroot;
210 Then create the following script to get list of project in the format
211 suitable for GITWEB_LIST build configuration variable (or
212 $projects_list variable in gitweb config):
216 export GITWEB_CONFIG="gitweb_make_index.perl"
217 export GATEWAY_INTERFACE="CGI/1.1"
218 export HTTP_ACCEPT="*/*"
219 export REQUEST_METHOD="GET"
220 export QUERY_STRING="a=project_index"
222 perl -- /var/www/cgi-bin/gitweb.cgi
