1 GIT web Interface (gitweb) Installation
2 =======================================
4 First you have to generate gitweb.cgi from gitweb.perl using
5 "make gitweb", then copy appropriate files (gitweb.cgi, gitweb.js,
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 ;# 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 ;# 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 target.
36 One of the most important is where to find the git wrapper binary. Gitweb
37 tries to find the git wrapper at $(bindir)/git, so you have to set $bindir
38 when building gitweb.cgi, or $prefix from which $bindir is derived. If
39 you build and install gitweb together with the rest of the git suite,
40 there should be no problems. Otherwise, if git was for example
41 installed from a binary package, you have to set $prefix (or $bindir)
44 - Another important issue is where are git repositories you want to make
45 available to gitweb. By default gitweb searches for repositories under
46 /pub/git; if you want to have projects somewhere else, like /home/git,
47 use GITWEB_PROJECTROOT build configuration variable.
49 By default all git repositories under projectroot are visible and
50 available to gitweb. The list of projects is generated by default by
51 scanning the projectroot directory for git repositories. This can be
52 changed (configured) as described in "Gitweb repositories" section
55 Note that gitweb deals directly with the object database, and does not
56 need a working directory; the name of the project is the name of its
57 repository object database, usually projectname.git for bare
58 repositories. If you want to provide gitweb access to non-bare (live)
59 repositories, you can make projectname.git a symbolic link under
60 projectroot linking to projectname/.git (but it is just
63 - You can control where gitweb tries to find its main CSS style file,
64 its JavaScript file, its favicon and logo with the GITWEB_CSS, GITWEB_JS
65 GITWEB_FAVICON and GITWEB_LOGO build configuration variables. By default
66 gitweb tries to find them in the same directory as gitweb.cgi script.
68 - You can optionally generate minified versions of gitweb.js and gitweb.css
69 by defining the JSMIN and CSSMIN build configuration variables. By default
70 the non-minified versions will be used. NOTE: if you enable this option,
71 substitute gitweb.min.js and gitweb.min.css for all uses of gitweb.js and
72 gitweb.css in the help files.
77 - To install gitweb to /var/www/cgi-bin/gitweb/ when git wrapper
78 is installed at /usr/local/bin/git and the repositories (projects)
79 we want to display are under /home/local/scm, you can do
81 make GITWEB_PROJECTROOT="/home/local/scm" \
82 GITWEB_JS="/gitweb/gitweb.js" \
83 GITWEB_CSS="/gitweb/gitweb.css" \
84 GITWEB_LOGO="/gitweb/git-logo.png" \
85 GITWEB_FAVICON="/gitweb/git-favicon.png" \
86 bindir=/usr/local/bin \
89 cp -fv ~/git/gitweb/gitweb.{cgi,js,css} \
90 ~/git/gitweb/git-{favicon,logo}.png \
91 /var/www/cgi-bin/gitweb/
97 See also "Runtime gitweb configuration" section in README file
98 for gitweb (in gitweb/README).
100 - You can configure gitweb further using the gitweb configuration file;
101 by default this is a file named gitweb_config.perl in the same place as
102 gitweb.cgi script. You can control the default place for the config file
103 using the GITWEB_CONFIG build configuration variable, and you can set it
104 using the GITWEB_CONFIG environment variable. If this file does not
105 exist, gitweb looks for a system-wide configuration file, normally
106 /etc/gitweb.conf. You can change the default using the
107 GITWEB_CONFIG_SYSTEM build configuration variable, and override it
108 through the GITWEB_CONFIG_SYSTEM environment variable.
110 - The gitweb config file is a fragment of perl code. You can set variables
111 using "our $variable = value"; text from "#" character until the end
112 of a line is ignored. See perlsyn(1) for details.
114 See the top of gitweb.perl file for examples of customizable options.
119 To enable blame, pickaxe search, and snapshot support, while allowing
120 individual projects to turn them off, put the following in your
123 $feature{'blame'}{'default'} = [1];
124 $feature{'blame'}{'override'} = 1;
126 $feature{'pickaxe'}{'default'} = [1];
127 $feature{'pickaxe'}{'override'} = 1;
129 $feature{'snapshot'}{'default'} = ['zip', 'tgz'];
130 $feature{'snapshot'}{'override'} = 1;
132 If you allow overriding for the snapshot feature, you can specify which
133 snapshot formats are globally disabled. You can also add any command line
134 options you want (such as setting the compression level). For instance,
135 you can disable Zip compressed snapshots and set GZip to run at level 6 by
136 adding the following lines to your $GITWEB_CONFIG:
138 $known_snapshot_formats{'zip'}{'disabled'} = 1;
139 $known_snapshot_formats{'tgz'}{'compressor'} = ['gzip','-6'];
145 - By default all git repositories under projectroot are visible and
146 available to gitweb. The list of projects is generated by default by
147 scanning the projectroot directory for git repositories (for object
148 databases to be more exact).
150 You can provide a pre-generated list of [visible] repositories,
151 together with information about their owners (the project ownership
152 defaults to the owner of the repository directory otherwise), by setting
153 the GITWEB_LIST build configuration variable (or the $projects_list
154 variable in the gitweb config file) to point to a plain file.
156 Each line of the projects list file should consist of the url-encoded path
157 to the project repository database (relative to projectroot), followed
158 by the url-encoded project owner on the same line (separated by a space).
159 Spaces in both project path and project owner have to be encoded as either
162 Other characters that have to be url-encoded, i.e. replaced by '%'
163 followed by two-digit character number in octal, are: other whitespace
164 characters (because they are field separator in a record), plus sign '+'
165 (because it can be used as replacement for spaces), and percent sign '%'
166 (which is used for encoding / escaping).
168 You can generate the projects list index file using the project_index
169 action (the 'TXT' link on projects list page) directly from gitweb.
171 - By default, even if a project is not visible on projects list page, you
172 can view it nevertheless by hand-crafting a gitweb URL. You can set the
173 GITWEB_STRICT_EXPORT build configuration variable (or the $strict_export
174 variable in the gitweb config file) to only allow viewing of
175 repositories also shown on the overview page.
177 - Alternatively, you can configure gitweb to only list and allow
178 viewing of the explicitly exported repositories, via the
179 GITWEB_EXPORT_OK build configuration variable (or the $export_ok
180 variable in gitweb config file). If it evaluates to true, gitweb
181 shows repositories only if this file exists in its object database
182 (if directory has the magic file named $export_ok).
184 - Finally, it is possible to specify an arbitrary perl subroutine that
185 will be called for each project to determine if it can be exported.
186 The subroutine receives an absolute path to the project as its only
189 For example, if you use mod_perl to run the script, and have dumb
190 http protocol authentication configured for your repositories, you
191 can use the following hook to allow access only if the user is
192 authorized to read the files:
194 $export_auth_hook = sub {
195 use Apache2::SubRequest ();
196 use Apache2::Const -compile => qw(HTTP_OK);
197 my $path = "$_[0]/HEAD";
198 my $r = Apache2::RequestUtil->request;
199 my $sub = $r->lookup_file($path);
200 return $sub->filename eq $path
201 && $sub->status == Apache2::Const::HTTP_OK;
205 Generating projects list using gitweb
206 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
208 We assume that GITWEB_CONFIG has its default Makefile value, namely
209 gitweb_config.perl. Put the following in gitweb_make_index.perl file:
211 $GITWEB_CONFIG = "gitweb_config.perl";
212 do $GITWEB_CONFIG if -e $GITWEB_CONFIG;
214 $projects_list = $projectroot;
216 Then create the following script to get list of project in the format
217 suitable for GITWEB_LIST build configuration variable (or
218 $projects_list variable in gitweb config):
222 export GITWEB_CONFIG="gitweb_make_index.perl"
223 export GATEWAY_INTERFACE="CGI/1.1"
224 export HTTP_ACCEPT="*/*"
225 export REQUEST_METHOD="GET"
226 export QUERY_STRING="a=project_index"
