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
15 instead
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
25 scripts).
28 Requirements
29 ------------
31 - Core git tools
32 - Perl 5.8
33 - Perl modules: CGI, Encode, Fcntl, File::Find, File::Basename.
34 - web server
36 The following optional Perl modules are required for extra features
37 - CGI::Fast and FCGI - for running gitweb as FastCGI script
38 - HTML::TagCloud - for fancy tag cloud in project list view
39 - HTTP::Date or Time::ParseDate - to support If-Modified-Since for feeds
42 Build time configuration
43 ------------------------
45 See also "How to configure gitweb for your local system" section below.
47 - There are many configuration variables which affect building of
48 gitweb.cgi; see "default configuration for gitweb" section in main
49 (top dir) Makefile, and instructions for building gitweb target.
51 One of the most important is where to find the git wrapper binary. Gitweb
52 tries to find the git wrapper at $(bindir)/git, so you have to set $bindir
53 when building gitweb.cgi, or $prefix from which $bindir is derived. If
54 you build and install gitweb together with the rest of the git suite,
55 there should be no problems. Otherwise, if git was for example
56 installed from a binary package, you have to set $prefix (or $bindir)
57 accordingly.
59 - Another important issue is where are git repositories you want to make
60 available to gitweb. By default gitweb searches for repositories under
61 /pub/git; if you want to have projects somewhere else, like /home/git,
62 use GITWEB_PROJECTROOT build configuration variable.
64 By default all git repositories under projectroot are visible and
65 available to gitweb. The list of projects is generated by default by
66 scanning the projectroot directory for git repositories. This can be
67 changed (configured) as described in "Gitweb repositories" section
68 below.
70 Note that gitweb deals directly with the object database, and does not
71 need a working directory; the name of the project is the name of its
72 repository object database, usually projectname.git for bare
73 repositories. If you want to provide gitweb access to non-bare (live)
74 repositories, you can make projectname.git a symbolic link under
75 projectroot linking to projectname/.git (but it is just
76 a suggestion).
78 - You can control where gitweb tries to find its main CSS style file,
79 its JavaScript file, its favicon and logo with the GITWEB_CSS, GITWEB_JS
80 GITWEB_FAVICON and GITWEB_LOGO build configuration variables. By default
81 gitweb tries to find them in the same directory as gitweb.cgi script.
83 - You can optionally generate minified versions of gitweb.js and gitweb.css
84 by defining the JSMIN and CSSMIN build configuration variables. By default
85 the non-minified versions will be used. NOTE: if you enable this option,
86 substitute gitweb.min.js and gitweb.min.css for all uses of gitweb.js and
87 gitweb.css in the help files.
90 How to configure gitweb for your local system
91 ---------------------------------------------
93 You can specify the following configuration variables when building GIT:
96 Points where to find the git executable. You should set it up to
97 the place where the git binary was installed (usually /usr/bin) if you
98 don't install git from sources together with gitweb. [Default: $(bindir)]
100 Shown in the title of all generated pages, defaults to the server name
101 (SERVER_NAME CGI environment variable) if not set. [No default]
103 The root directory for all projects shown by gitweb. Must be set
104 correctly for gitweb to find repositories to display. See also
105 "Gitweb repositories" in the INSTALL file for gitweb. [Default: /pub/git]
107 The filesystem traversing limit for getting the project list; the number
108 is taken as depth relative to the projectroot. It is used when
109 GITWEB_LIST is a directory (or is not set; then project root is used).
110 This is meant to speed up project listing on large work trees by limiting
111 search depth. [Default: 2007]
113 Points to a directory to scan for projects (defaults to project root
114 if not set / if empty) or to a file with explicit listing of projects
115 (together with projects' ownership). See "Generating projects list
116 using gitweb" in INSTALL file for gitweb to find out how to generate
117 such file from scan of a directory. [No default, which means use root
118 directory for projects]
120 Show repository only if this file exists (in repository). Only
121 effective if this variable evaluates to true. [No default / Not set]
123 Only allow viewing of repositories also shown on the overview page.
124 This for example makes GITWEB_EXPORT_OK to decide if repository is
125 available and not only if it is shown. If GITWEB_LIST points to
126 file with list of project, only those repositories listed would be
127 available for gitweb. [No default]
129 Points to an .html file which is included on the gitweb project
130 overview page ('projects_list' view), if it exists. Relative to
131 gitweb.cgi script. [Default: indextext.html]
133 html snippet to include in the <head> section of each page. [No default]
135 Filename of html text to include at top of each page. Relative to
136 gitweb.cgi script. [No default]
138 Filename of html text to include at bottom of each page. Relative to
139 gitweb.cgi script. [No default]
141 String of the home link on top of all pages, leading to $home_link
142 (usually main gitweb page, which means projects list). Used as first
143 part of gitweb view "breadcrumb trail": <home> / <project> / <view>.
144 [Default: projects]
146 Name of your site or organization to appear in page titles. Set it
147 to something descriptive for clearer bookmarks etc. If not set
148 (if empty) gitweb uses "$SERVER_NAME Git", or "Untitled Git" if
149 SERVER_NAME CGI environment variable is not set (e.g. if running
150 gitweb as standalone script). [No default]
152 Git base URLs used for URL to where fetch project from, i.e. full
153 URL is "$git_base_url/$project". Shown on projects summary page.
154 Repository URL for project can be also configured per repository; this
155 takes precedence over URLs composed from base URL and a project name.
156 Note that you can setup multiple base URLs (for example one for
157 git:// protocol access, another for http:// access) from the gitweb
158 config file. [No default]
160 Points to the location where you put gitweb.css on your web server
161 (or to be more generic, the URI of gitweb stylesheet). Relative to the
162 base URI of gitweb. Note that you can setup multiple stylesheets from
163 the gitweb config file. [Default: static/gitweb.css (or
164 static/gitweb.min.css if the CSSMIN variable is defined / CSS minifier
165 is used)]
167 Points to the location where you put gitweb.js on your web server
168 (or to be more generic URI of JavaScript code used by gitweb).
169 Relative to base URI of gitweb. [Default: static/gitweb.js (or
170 static/gitweb.min.js if JSMIN build variable is defined / JavaScript
171 minifier is used)]
173 Invocation of a CSS minifier or a JavaScript minifier, respectively,
174 working as a filter (source on standard input, minified result on
175 standard output). If set, it is used to generate a minified version of
176 'static/gitweb.css' or 'static/gitweb.js', respectively. *Note* that
177 minified files would have *.min.css and *.min.js extension, which is
178 important if you also set GITWEB_CSS and/or GITWEB_JS. [No default]
180 Points to the location where you put git-logo.png on your web server
181 (or to be more generic URI of logo, 72x27 size, displayed in top right
182 corner of each gitweb page, and used as logo for Atom feed). Relative
183 to base URI of gitweb. [Default: static/git-logo.png]
185 Points to the location where you put git-favicon.png on your web server
186 (or to be more generic URI of favicon, assumed to be image/png type;
187 web browsers that support favicons (website icons) may display them
188 in the browser's URL bar and next to site name in bookmarks). Relative
189 to base URI of gitweb. [Default: static/git-favicon.png]
191 This Perl file will be loaded using 'do' and can be used to override any
192 of the options above as well as some other options -- see the "Runtime
193 gitweb configuration" section below, and top of 'gitweb.cgi' for their
194 full list and description. If the environment variable GITWEB_CONFIG
195 is set when gitweb.cgi is executed, then the file specified in the
196 environment variable will be loaded instead of the file specified
197 when gitweb.cgi was created. [Default: gitweb_config.perl]
199 This Perl file will be loaded using 'do' as a fallback if GITWEB_CONFIG
200 does not exist. If the environment variable GITWEB_CONFIG_SYSTEM is set
201 when gitweb.cgi is executed, then the file specified in the environment
202 variable will be loaded instead of the file specified when gitweb.cgi was
203 created. [Default: /etc/gitweb.conf]
205 Path to the highlight executable to use (must be the one from
206 due to assumptions about parameters and output).
207 Useful if highlight is not installed on your webserver's PATH.
208 [Default: highlight]
210 Build example
211 ~~~~~~~~~~~~~
213 - To install gitweb to /var/www/cgi-bin/gitweb/, when git wrapper
214 is installed at /usr/local/bin/git, the repositories (projects)
215 we want to display are under /home/local/scm, and you do not use
216 minifiers, you can do
218 make GITWEB_PROJECTROOT="/home/local/scm" \
219 GITWEB_JS="gitweb/static/gitweb.js" \
220 GITWEB_CSS="gitweb/static/gitweb.css" \
221 GITWEB_LOGO="gitweb/static/git-logo.png" \
222 GITWEB_FAVICON="gitweb/static/git-favicon.png" \
223 bindir=/usr/local/bin \
224 gitweb
226 make gitwebdir=/var/www/cgi-bin/gitweb install-gitweb
229 Gitweb config file
230 ------------------
232 See also "Runtime gitweb configuration" section in README file
233 for gitweb (in gitweb/README), and gitweb.conf(5) manpage.
235 - You can configure gitweb further using the per-instance gitweb configuration file;
236 by default this is a file named gitweb_config.perl in the same place as
237 gitweb.cgi script. You can control the default place for the config file
238 using the GITWEB_CONFIG build configuration variable, and you can set it
239 using the GITWEB_CONFIG environment variable. If this file does not
240 exist, gitweb looks for a system-wide configuration file, normally
241 /etc/gitweb.conf. You can change the default using the
242 GITWEB_CONFIG_SYSTEM build configuration variable, and override it
243 through the GITWEB_CONFIG_SYSTEM environment variable.
245 Note that the GITWEB_CONFIG_SYSTEM system-wide configuration file is
246 only used for instances that lack per-instance configuration file.
247 You can use GITWEB_CONFIG_COMMON common system-wide configuration
248 file (normally /etc/gitweb-common.conf) to keep common default
249 settings that apply to all instances. Settings from per-instance or
250 system-wide configuration file override those from common system-wide
251 configuration file.
253 - The gitweb config file is a fragment of perl code. You can set variables
254 using "our $variable = value"; text from "#" character until the end
255 of a line is ignored. See perlsyn(1) for details.
257 See the top of gitweb.perl file for examples of customizable options.
259 Config file example
260 ~~~~~~~~~~~~~~~~~~~
262 To enable blame, pickaxe search, and snapshot support, while allowing
263 individual projects to turn them off, put the following in your
266 $feature{'blame'}{'default'} = [1];
267 $feature{'blame'}{'override'} = 1;
269 $feature{'pickaxe'}{'default'} = [1];
270 $feature{'pickaxe'}{'override'} = 1;
272 $feature{'snapshot'}{'default'} = ['zip', 'tgz'];
273 $feature{'snapshot'}{'override'} = 1;
275 If you allow overriding for the snapshot feature, you can specify which
276 snapshot formats are globally disabled. You can also add any command line
277 options you want (such as setting the compression level). For instance,
278 you can disable Zip compressed snapshots and set GZip to run at level 6 by
279 adding the following lines to your $GITWEB_CONFIG:
281 $known_snapshot_formats{'zip'}{'disabled'} = 1;
282 $known_snapshot_formats{'tgz'}{'compressor'} = ['gzip','-6'];
285 Gitweb repositories
286 -------------------
288 By default gitweb shows all git repositories under single common repository
289 root on a local filesystem; see description of GITWEB_PROJECTROOT build-time
290 configuration variable above (and also of GITWEB_LIST).
292 More advanced usage, like limiting access or visibility of repositories and
293 managing multiple roots are described on gitweb manpage.
