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 # make gitwebdir=/var/www/cgi-bin install-gitweb ;# 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 # make gitwebdir=/var/www/cgi-bin \
20 install-gitweb ;# as root
22 The above example assumes that your web server is configured to run
23 [executable] files in /var/www/cgi-bin/ as server scripts (as CGI
27 Build time configuration
28 ------------------------
30 See also "How to configure gitweb for your local system" in README
31 file for gitweb (in gitweb/README).
33 - There are many configuration variables which affect building of
34 gitweb.cgi; see "default configuration for gitweb" section in main
35 (top dir) Makefile, and instructions for building gitweb target.
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 JavaScript file, its favicon and logo with the GITWEB_CSS, GITWEB_JS
66 GITWEB_FAVICON and GITWEB_LOGO build configuration variables. By default
67 gitweb tries to find them in the same directory as gitweb.cgi script.
69 - You can optionally generate minified versions of gitweb.js and gitweb.css
70 by defining the JSMIN and CSSMIN build configuration variables. By default
71 the non-minified versions will be used. NOTE: if you enable this option,
72 substitute gitweb.min.js and gitweb.min.css for all uses of gitweb.js and
73 gitweb.css in the help files.
78 - To install gitweb to /var/www/cgi-bin/gitweb/, when git wrapper
79 is installed at /usr/local/bin/git, the repositories (projects)
80 we want to display are under /home/local/scm, and you do not use
83 make GITWEB_PROJECTROOT="/home/local/scm" \
84 GITWEB_JS="/gitweb/gitweb.js" \
85 GITWEB_CSS="/gitweb/gitweb.css" \
86 GITWEB_LOGO="/gitweb/git-logo.png" \
87 GITWEB_FAVICON="/gitweb/git-favicon.png" \
88 bindir=/usr/local/bin \
91 cp -fv gitweb/gitweb.{cgi,js,css} \
92 gitweb/git-{favicon,logo}.png \
93 /var/www/cgi-bin/gitweb/
99 See also "Runtime gitweb configuration" section in README file
100 for gitweb (in gitweb/README).
102 - You can configure gitweb further using the gitweb configuration file;
103 by default this is a file named gitweb_config.perl in the same place as
104 gitweb.cgi script. You can control the default place for the config file
105 using the GITWEB_CONFIG build configuration variable, and you can set it
106 using the GITWEB_CONFIG environment variable. If this file does not
107 exist, gitweb looks for a system-wide configuration file, normally
108 /etc/gitweb.conf. You can change the default using the
109 GITWEB_CONFIG_SYSTEM build configuration variable, and override it
110 through the GITWEB_CONFIG_SYSTEM environment variable.
112 - The gitweb config file is a fragment of perl code. You can set variables
113 using "our $variable = value"; text from "#" character until the end
114 of a line is ignored. See perlsyn(1) for details.
116 See the top of gitweb.perl file for examples of customizable options.
121 To enable blame, pickaxe search, and snapshot support, while allowing
122 individual projects to turn them off, put the following in your
125 $feature{'blame'}{'default'} = [1];
126 $feature{'blame'}{'override'} = 1;
128 $feature{'pickaxe'}{'default'} = [1];
129 $feature{'pickaxe'}{'override'} = 1;
131 $feature{'snapshot'}{'default'} = ['zip', 'tgz'];
132 $feature{'snapshot'}{'override'} = 1;
134 If you allow overriding for the snapshot feature, you can specify which
135 snapshot formats are globally disabled. You can also add any command line
136 options you want (such as setting the compression level). For instance,
137 you can disable Zip compressed snapshots and set GZip to run at level 6 by
138 adding the following lines to your $GITWEB_CONFIG:
140 $known_snapshot_formats{'zip'}{'disabled'} = 1;
141 $known_snapshot_formats{'tgz'}{'compressor'} = ['gzip','-6'];
147 - By default all git repositories under projectroot are visible and
148 available to gitweb. The list of projects is generated by default by
149 scanning the projectroot directory for git repositories (for object
150 databases to be more exact).
152 You can provide a pre-generated list of [visible] repositories,
153 together with information about their owners (the project ownership
154 defaults to the owner of the repository directory otherwise), by setting
155 the GITWEB_LIST build configuration variable (or the $projects_list
156 variable in the gitweb config file) to point to a plain file.
158 Each line of the projects list file should consist of the url-encoded path
159 to the project repository database (relative to projectroot), followed
160 by the url-encoded project owner on the same line (separated by a space).
161 Spaces in both project path and project owner have to be encoded as either
164 Other characters that have to be url-encoded, i.e. replaced by '%'
165 followed by two-digit character number in octal, are: other whitespace
166 characters (because they are field separator in a record), plus sign '+'
167 (because it can be used as replacement for spaces), and percent sign '%'
168 (which is used for encoding / escaping).
170 You can generate the projects list index file using the project_index
171 action (the 'TXT' link on projects list page) directly from gitweb.
173 - By default, even if a project is not visible on projects list page, you
174 can view it nevertheless by hand-crafting a gitweb URL. You can set the
175 GITWEB_STRICT_EXPORT build configuration variable (or the $strict_export
176 variable in the gitweb config file) to only allow viewing of
177 repositories also shown on the overview page.
179 - Alternatively, you can configure gitweb to only list and allow
180 viewing of the explicitly exported repositories, via the
181 GITWEB_EXPORT_OK build configuration variable (or the $export_ok
182 variable in gitweb config file). If it evaluates to true, gitweb
183 shows repositories only if this file exists in its object database
184 (if directory has the magic file named $export_ok).
186 - Finally, it is possible to specify an arbitrary perl subroutine that
187 will be called for each project to determine if it can be exported.
188 The subroutine receives an absolute path to the project as its only
191 For example, if you use mod_perl to run the script, and have dumb
192 http protocol authentication configured for your repositories, you
193 can use the following hook to allow access only if the user is
194 authorized to read the files:
196 $export_auth_hook = sub {
197 use Apache2::SubRequest ();
198 use Apache2::Const -compile => qw(HTTP_OK);
199 my $path = "$_[0]/HEAD";
200 my $r = Apache2::RequestUtil->request;
201 my $sub = $r->lookup_file($path);
202 return $sub->filename eq $path
203 && $sub->status == Apache2::Const::HTTP_OK;
207 Generating projects list using gitweb
208 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
210 We assume that GITWEB_CONFIG has its default Makefile value, namely
211 gitweb_config.perl. Put the following in gitweb_make_index.perl file:
213 $GITWEB_CONFIG = "gitweb_config.perl";
214 do $GITWEB_CONFIG if -e $GITWEB_CONFIG;
216 $projects_list = $projectroot;
218 Then create the following script to get list of project in the format
219 suitable for GITWEB_LIST build configuration variable (or
220 $projects_list variable in gitweb config):
224 export GITWEB_CONFIG="gitweb_make_index.perl"
225 export GATEWAY_INTERFACE="CGI/1.1"
226 export HTTP_ACCEPT="*/*"
227 export REQUEST_METHOD="GET"
228 export QUERY_STRING="a=project_index"
230 perl -- /var/www/cgi-bin/gitweb.cgi
