1 GIT web Interface (gitweb) Installation
2 =======================================
4 First you have to generate gitweb.cgi from gitweb.perl using
5 "make gitweb", then "make install-gitweb" appropriate files
6 (gitweb.cgi, gitweb.js, gitweb.css, git-logo.png and git-favicon.png)
7 to their destination. For example if git was (or is) installed with
8 /usr prefix and gitwebdir is /var/www/cgi-bin, you can do
10 $ make prefix=/usr gitweb ;# as yourself
11 # make gitwebdir=/var/www/cgi-bin install-gitweb ;# as root
13 Alternatively you can use autoconf generated ./configure script to
14 set up path to git binaries (via config.mak.autogen), so you can write
17 $ make configure ;# as yourself
18 $ ./configure --prefix=/usr ;# as yourself
19 $ make gitweb ;# as yourself
20 # make gitwebdir=/var/www/cgi-bin \
21 install-gitweb ;# as root
23 The above example assumes that your web server is configured to run
24 [executable] files in /var/www/cgi-bin/ as server scripts (as CGI
28 Build time configuration
29 ------------------------
31 See also "How to configure gitweb for your local system" section below.
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.
76 How to configure gitweb for your local system
77 ---------------------------------------------
79 You can specify the following configuration variables when building GIT:
82 Points where to find the git executable. You should set it up to
83 the place where the git binary was installed (usually /usr/bin) if you
84 don't install git from sources together with gitweb. [Default: $(bindir)]
86 Shown in the title of all generated pages, defaults to the server name
87 (SERVER_NAME CGI environment variable) if not set. [No default]
89 The root directory for all projects shown by gitweb. Must be set
90 correctly for gitweb to find repositories to display. See also
91 "Gitweb repositories" in the INSTALL file for gitweb. [Default: /pub/git]
92 * GITWEB_PROJECT_MAXDEPTH
93 The filesystem traversing limit for getting the project list; the number
94 is taken as depth relative to the projectroot. It is used when
95 GITWEB_LIST is a directory (or is not set; then project root is used).
96 This is meant to speed up project listing on large work trees by limiting
97 search depth. [Default: 2007]
99 Points to a directory to scan for projects (defaults to project root
100 if not set / if empty) or to a file with explicit listing of projects
101 (together with projects' ownership). See "Generating projects list
102 using gitweb" in INSTALL file for gitweb to find out how to generate
103 such file from scan of a directory. [No default, which means use root
104 directory for projects]
106 Show repository only if this file exists (in repository). Only
107 effective if this variable evaluates to true. [No default / Not set]
108 * GITWEB_STRICT_EXPORT
109 Only allow viewing of repositories also shown on the overview page.
110 This for example makes GITWEB_EXPORT_OK to decide if repository is
111 available and not only if it is shown. If GITWEB_LIST points to
112 file with list of project, only those repositories listed would be
113 available for gitweb. [No default]
115 Points to an .html file which is included on the gitweb project
116 overview page ('projects_list' view), if it exists. Relative to
117 gitweb.cgi script. [Default: indextext.html]
119 Filename of html text to include at top of each page. Relative to
120 gitweb.cgi script. [No default]
122 Filename of html text to include at bottom of each page. Relative to
123 gitweb.cgi script. [No default]
124 * GITWEB_HOME_LINK_STR
125 String of the home link on top of all pages, leading to $home_link
126 (usually main gitweb page, which means projects list). Used as first
127 part of gitweb view "breadcrumb trail": <home> / <project> / <view>.
130 Name of your site or organization to appear in page titles. Set it
131 to something descriptive for clearer bookmarks etc. If not set
132 (if empty) gitweb uses "$SERVER_NAME Git", or "Untitled Git" if
133 SERVER_NAME CGI environment variable is not set (e.g. if running
134 gitweb as standalone script). [No default]
136 Git base URLs used for URL to where fetch project from, i.e. full
137 URL is "$git_base_url/$project". Shown on projects summary page.
138 Repository URL for project can be also configured per repository; this
139 takes precedence over URLs composed from base URL and a project name.
140 Note that you can setup multiple base URLs (for example one for
141 git:// protocol access, another for http:// access) from the gitweb
142 config file. [No default]
144 Points to the location where you put gitweb.css on your web server
145 (or to be more generic, the URI of gitweb stylesheet). Relative to the
146 base URI of gitweb. Note that you can setup multiple stylesheets from
147 the gitweb config file. [Default: static/gitweb.css (or
148 static/gitweb.min.css if the CSSMIN variable is defined / CSS minifier
151 Points to the location where you put git-logo.png on your web server
152 (or to be more generic URI of logo, 72x27 size, displayed in top right
153 corner of each gitweb page, and used as logo for Atom feed). Relative
154 to base URI of gitweb. [Default: static/git-logo.png]
156 Points to the location where you put git-favicon.png on your web server
157 (or to be more generic URI of favicon, assumed to be image/png type;
158 web browsers that support favicons (website icons) may display them
159 in the browser's URL bar and next to site name in bookmarks). Relative
160 to base URI of gitweb. [Default: static/git-favicon.png]
162 Points to the location where you put gitweb.js on your web server
163 (or to be more generic URI of JavaScript code used by gitweb).
164 Relative to base URI of gitweb. [Default: static/gitweb.js (or
165 static/gitweb.min.js if JSMIN build variable is defined / JavaScript
168 This Perl file will be loaded using 'do' and can be used to override any
169 of the options above as well as some other options -- see the "Runtime
170 gitweb configuration" section below, and top of 'gitweb.cgi' for their
171 full list and description. If the environment variable GITWEB_CONFIG
172 is set when gitweb.cgi is executed, then the file specified in the
173 environment variable will be loaded instead of the file specified
174 when gitweb.cgi was created. [Default: gitweb_config.perl]
175 * GITWEB_CONFIG_SYSTEM
176 This Perl file will be loaded using 'do' as a fallback if GITWEB_CONFIG
177 does not exist. If the environment variable GITWEB_CONFIG_SYSTEM is set
178 when gitweb.cgi is executed, then the file specified in the environment
179 variable will be loaded instead of the file specified when gitweb.cgi was
180 created. [Default: /etc/gitweb.conf]
182 Path to the highlight executable to use (must be the one from
183 http://www.andre-simon.de due to assumptions about parameters and output).
184 Useful if highlight is not installed on your webserver's PATH.
190 - To install gitweb to /var/www/cgi-bin/gitweb/, when git wrapper
191 is installed at /usr/local/bin/git, the repositories (projects)
192 we want to display are under /home/local/scm, and you do not use
193 minifiers, you can do
195 make GITWEB_PROJECTROOT="/home/local/scm" \
196 GITWEB_JS="gitweb/static/gitweb.js" \
197 GITWEB_CSS="gitweb/static/gitweb.css" \
198 GITWEB_LOGO="gitweb/static/git-logo.png" \
199 GITWEB_FAVICON="gitweb/static/git-favicon.png" \
200 bindir=/usr/local/bin \
203 make gitwebdir=/var/www/cgi-bin/gitweb install-gitweb
209 See also "Runtime gitweb configuration" section in README file
210 for gitweb (in gitweb/README).
212 - You can configure gitweb further using the gitweb configuration file;
213 by default this is a file named gitweb_config.perl in the same place as
214 gitweb.cgi script. You can control the default place for the config file
215 using the GITWEB_CONFIG build configuration variable, and you can set it
216 using the GITWEB_CONFIG environment variable. If this file does not
217 exist, gitweb looks for a system-wide configuration file, normally
218 /etc/gitweb.conf. You can change the default using the
219 GITWEB_CONFIG_SYSTEM build configuration variable, and override it
220 through the GITWEB_CONFIG_SYSTEM environment variable.
222 - The gitweb config file is a fragment of perl code. You can set variables
223 using "our $variable = value"; text from "#" character until the end
224 of a line is ignored. See perlsyn(1) for details.
226 See the top of gitweb.perl file for examples of customizable options.
231 To enable blame, pickaxe search, and snapshot support, while allowing
232 individual projects to turn them off, put the following in your
235 $feature{'blame'}{'default'} = [1];
236 $feature{'blame'}{'override'} = 1;
238 $feature{'pickaxe'}{'default'} = [1];
239 $feature{'pickaxe'}{'override'} = 1;
241 $feature{'snapshot'}{'default'} = ['zip', 'tgz'];
242 $feature{'snapshot'}{'override'} = 1;
244 If you allow overriding for the snapshot feature, you can specify which
245 snapshot formats are globally disabled. You can also add any command line
246 options you want (such as setting the compression level). For instance,
247 you can disable Zip compressed snapshots and set GZip to run at level 6 by
248 adding the following lines to your $GITWEB_CONFIG:
250 $known_snapshot_formats{'zip'}{'disabled'} = 1;
251 $known_snapshot_formats{'tgz'}{'compressor'} = ['gzip','-6'];
257 - By default all git repositories under projectroot are visible and
258 available to gitweb. The list of projects is generated by default by
259 scanning the projectroot directory for git repositories (for object
260 databases to be more exact).
262 You can provide a pre-generated list of [visible] repositories,
263 together with information about their owners (the project ownership
264 defaults to the owner of the repository directory otherwise), by setting
265 the GITWEB_LIST build configuration variable (or the $projects_list
266 variable in the gitweb config file) to point to a plain file.
268 Each line of the projects list file should consist of the url-encoded path
269 to the project repository database (relative to projectroot), followed
270 by the url-encoded project owner on the same line (separated by a space).
271 Spaces in both project path and project owner have to be encoded as either
274 Other characters that have to be url-encoded, i.e. replaced by '%'
275 followed by two-digit character number in octal, are: other whitespace
276 characters (because they are field separator in a record), plus sign '+'
277 (because it can be used as replacement for spaces), and percent sign '%'
278 (which is used for encoding / escaping).
280 You can generate the projects list index file using the project_index
281 action (the 'TXT' link on projects list page) directly from gitweb.
283 - By default, even if a project is not visible on projects list page, you
284 can view it nevertheless by hand-crafting a gitweb URL. You can set the
285 GITWEB_STRICT_EXPORT build configuration variable (or the $strict_export
286 variable in the gitweb config file) to only allow viewing of
287 repositories also shown on the overview page.
289 - Alternatively, you can configure gitweb to only list and allow
290 viewing of the explicitly exported repositories, via the
291 GITWEB_EXPORT_OK build configuration variable (or the $export_ok
292 variable in gitweb config file). If it evaluates to true, gitweb
293 shows repositories only if this file exists in its object database
294 (if directory has the magic file named $export_ok).
296 - Finally, it is possible to specify an arbitrary perl subroutine that
297 will be called for each project to determine if it can be exported.
298 The subroutine receives an absolute path to the project as its only
301 For example, if you use mod_perl to run the script, and have dumb
302 http protocol authentication configured for your repositories, you
303 can use the following hook to allow access only if the user is
304 authorized to read the files:
306 $export_auth_hook = sub {
307 use Apache2::SubRequest ();
308 use Apache2::Const -compile => qw(HTTP_OK);
309 my $path = "$_[0]/HEAD";
310 my $r = Apache2::RequestUtil->request;
311 my $sub = $r->lookup_file($path);
312 return $sub->filename eq $path
313 && $sub->status == Apache2::Const::HTTP_OK;
317 Generating projects list using gitweb
318 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
320 We assume that GITWEB_CONFIG has its default Makefile value, namely
321 gitweb_config.perl. Put the following in gitweb_make_index.perl file:
323 $GITWEB_CONFIG = "gitweb_config.perl";
324 do $GITWEB_CONFIG if -e $GITWEB_CONFIG;
326 $projects_list = $projectroot;
328 Then create the following script to get list of project in the format
329 suitable for GITWEB_LIST build configuration variable (or
330 $projects_list variable in gitweb config):
334 export GITWEB_CONFIG="gitweb_make_index.perl"
335 export GATEWAY_INTERFACE="CGI/1.1"
336 export HTTP_ACCEPT="*/*"
337 export REQUEST_METHOD="GET"
338 export QUERY_STRING="a=project_index"
340 perl -- /var/www/cgi-bin/gitweb.cgi
348 - Perl modules: CGI, Encode, Fcntl, File::Find, File::Basename.
351 The following optional Perl modules are required for extra features
352 - Digest::MD5 - for gravatar support
353 - CGI::Fast and FCGI - for running gitweb as FastCGI script
354 - HTML::TagCloud - for fancy tag cloud in project list view
355 - HTTP::Date or Time::ParseDate - to support If-Modified-Since for feeds
