<h2 id="_description">DESCRIPTION</h2>
<div class="sectionbody">
<div class="paragraph">
<p>Gitweb provides a web interface to Git repositories.  Its features include:</p>
</div>
<div class="ulist">
<ul>
<li>
<p>Viewing multiple Git repositories with common root.</p>
</li>
<li>
<p>Browsing every revision of the repository.</p>
</li>
<li>
<p>Viewing the contents of files in the repository at any revision.</p>
</li>
<li>
<p>Viewing the revision log of branches, history of files and directories,
seeing what was changed, when, and by whom.</p>
</li>
<li>
<p>Viewing the blame/annotation details of any file (if enabled).</p>
</li>
<li>
<p>Generating RSS and Atom feeds of commits, for any branch.
The feeds are auto-discoverable in modern web browsers.</p>
</li>
<li>
<p>Viewing everything that was changed in a revision, and stepping through
revisions one at a time, viewing the history of the repository.</p>
</li>
<li>
<p>Finding commits whose commit messages match a given search term.</p>
</li>
</ul>
</div>
<div class="paragraph">
<p>See <a href="https://repo.or.cz/w/git.git/tree/HEAD:/gitweb/" class="bare">https://repo.or.cz/w/git.git/tree/HEAD:/gitweb/</a> for gitweb source code,
browsed using gitweb itself.</p>
</div>
</div>
</div>
<div class="sect1">
<h2 id="_configuration">CONFIGURATION</h2>
<div class="sectionbody">
<div class="paragraph">
<p>Various aspects of gitweb&#8217;s behavior can be controlled through the configuration
file <code>gitweb_config.perl</code> or <code>/etc/gitweb.conf</code>.  See the <a href="gitweb.conf.html">gitweb.conf(5)</a>
for details.</p>
</div>
<div class="sect2">
<h3 id="_repositories">Repositories</h3>
<div class="paragraph">
<p>Gitweb can show information from one or more Git repositories.  These
repositories have to be all on local filesystem, and have to share a common
repository root, i.e. be all under a single parent repository (but see also
the "Advanced web server setup" section, "Webserver configuration with multiple
projects' root" subsection).</p>
</div>
<div class="listingblock">
<div class="content">
<pre>our $projectroot = '/path/to/parent/directory';</pre>
</div>
</div>
<div class="paragraph">
<p>The default value for <code>$projectroot</code> is <code>/pub/git</code>.  You can change it during
building gitweb via the <code>GITWEB_PROJECTROOT</code> build configuration variable.</p>
</div>
<div class="paragraph">
<p>By default all Git repositories under <code>$projectroot</code> are visible and available
to gitweb.  The list of projects is generated by default by scanning the
<code>$projectroot</code> directory for Git repositories (for object databases to be
more exact; gitweb is not interested in a working area, and is best suited
to showing "bare" repositories).</p>
</div>
<div class="paragraph">
<p>The name of the repository in gitweb is the path to its <code>$GIT_DIR</code> (its object
database) relative to <code>$projectroot</code>.  Therefore the repository $repo can be
found at "$projectroot/$repo".</p>
</div>
</div>
<div class="sect2">
<h3 id="_projects_list_file_format">Projects list file format</h3>
<div class="paragraph">
<p>Instead of having gitweb find repositories by scanning the filesystem
starting from $projectroot, you can provide a pre-generated list of
visible projects by setting <code>$projects_list</code> to point to a plain text
file with a list of projects (with some additional info).</p>
</div>
<div class="paragraph">
<p>This file uses the following format:</p>
</div>
<div class="ulist">
<ul>
<li>
<p>One record (for project / repository) per line; does not support line
continuation (newline escaping).</p>
</li>
<li>
<p>Leading and trailing whitespace are ignored.</p>
</li>
<li>
<p>Whitespace separated fields; any run of whitespace can be used as field
separator (rules for Perl&#8217;s "<code>split</code>(" ", <code>$line</code>)").</p>
</li>
<li>
<p>Fields use modified URI encoding, defined in RFC 3986, section 2.1
(Percent-Encoding), or rather "Query string encoding" (see
<a href="https://en.wikipedia.org/wiki/Query_string#URL_encoding" class="bare">https://en.wikipedia.org/wiki/Query_string#URL_encoding</a>), the difference
being that SP (" ") can be encoded as "&#43;" (and therefore "&#43;" has to be
also percent-encoded).</p>
<div class="paragraph">
<p>Reserved characters are: "%" (used for encoding), "&#43;" (can be used to
encode SPACE), all whitespace characters as defined in Perl, including SP,
TAB and LF, (used to separate fields in a record).</p>
</div>
</li>
<li>
<p>Currently recognized fields are:</p>
<div class="dlist">
<dl>
<dt class="hdlist1">&lt;repository path&gt;</dt>
<dd>
<p>path to repository GIT_DIR, relative to <code>$projectroot</code></p>
</dd>
<dt class="hdlist1">&lt;repository owner&gt;</dt>
<dd>
<p>displayed as repository owner, preferably full name, or email,
or both</p>
</dd>
</dl>
</div>
</li>
</ul>
</div>
<div class="paragraph">
<p>You can generate the projects list index file using the project_index action
(the <em>TXT</em> link on projects list page) directly from gitweb; see also
"Generating projects list using gitweb" section below.</p>
</div>
<div class="paragraph">
<p>Example contents:</p>
</div>
<div class="listingblock">
<div class="content">
<pre>foo.git       Joe+R+Hacker+&lt;joe@example.com&gt;
foo/bar.git   O+W+Ner+&lt;owner@example.org&gt;</pre>
</div>
</div>
<div class="paragraph">
<p>By default this file controls only which projects are <strong>visible</strong> on projects
list page (note that entries that do not point to correctly recognized Git
repositories won&#8217;t be displayed by gitweb).  Even if a project is not
visible on projects list page, you can view it nevertheless by hand-crafting
a gitweb URL.  By setting <code>$strict_export</code> configuration variable (see
<a href="gitweb.conf.html">gitweb.conf(5)</a>) to true value you can allow viewing only of
repositories also shown on the overview page (i.e. only projects explicitly
listed in projects list file will be accessible).</p>
</div>
</div>
<div class="sect2">
<h3 id="_generating_projects_list_using_gitweb">Generating projects list using gitweb</h3>
<div class="paragraph">
<p>We assume that GITWEB_CONFIG has its default Makefile value, namely
<em>gitweb_config.perl</em>. Put the following in <em>gitweb_make_index.perl</em> file:</p>
</div>
<div class="listingblock">
<div class="content">
<pre>read_config_file("gitweb_config.perl");
$projects_list = $projectroot;</pre>
</div>
</div>
<div class="paragraph">
<p>Then create the following script to get list of project in the format
suitable for GITWEB_LIST build configuration variable (or
<code>$projects_list</code> variable in gitweb config):</p>
</div>
<div class="listingblock">

</div>
</div>
<div class="paragraph">
<p>Run this script and save its output to a file.  This file could then be used
as projects list file, which means that you can set <code>$projects_list</code> to its
filename.</p>
</div>
</div>
<div class="sect2">
<h3 id="_controlling_access_to_git_repositories">Controlling access to Git repositories</h3>
<div class="paragraph">
<p>By default all Git repositories under <code>$projectroot</code> are visible and
available to gitweb.  You can however configure how gitweb controls access
to repositories.</p>
</div>
<div class="ulist">
<ul>
<li>
<p>As described in "Projects list file format" section, you can control which
projects are <strong>visible</strong> by selectively including repositories in projects
list file, and setting <code>$projects_list</code> gitweb configuration variable to
point to it.  With <code>$strict_export</code> set, projects list file can be used to
control which repositories are <strong>available</strong> as well.</p>
</li>
<li>
<p>You can configure gitweb to only list and allow viewing of the explicitly
exported repositories, via <code>$export_ok</code> variable in gitweb config file; see
<a href="gitweb.conf.html">gitweb.conf(5)</a> manpage.  If it evaluates to true, gitweb shows
repositories only if this file named by <code>$export_ok</code> exists in its object
database (if directory has the magic file named <code>$export_ok</code>).</p>
<div class="paragraph">
<p>For example <a href="git-daemon.html">git-daemon(1)</a> by default (unless <code>--export-all</code> option
is used) allows pulling only for those repositories that have
<em>git-daemon-export-ok</em> file.  Adding</p>
</div>
<div class="listingblock">
<div class="content">
<pre>our $export_ok = "git-daemon-export-ok";</pre>
</div>
</div>
<div class="paragraph">
<p>makes gitweb show and allow access only to those repositories that can be
fetched from via <code>git://</code> protocol.</p>
</div>
</li>
<li>
<p>Finally, it is possible to specify an arbitrary perl subroutine that will
be called for each repository to determine if it can be exported.  The
subroutine receives an absolute path to the project (repository) as its only
parameter (i.e. "$projectroot/$project").</p>
<div class="paragraph">
<p>For example, if you use mod_perl to run the script, and have dumb
HTTP protocol authentication configured for your repositories, you
can use the following hook to allow access only if the user is
authorized to read the files:</p>
</div>
<div class="listingblock">
<div class="content">
<pre>$export_auth_hook = sub {
        use Apache2::SubRequest ();
        use Apache2::Const -compile =&gt; qw(HTTP_OK);
        my $path = "$_[0]/HEAD";
        my $r    = Apache2::RequestUtil-&gt;request;
        my $sub  = $r-&gt;lookup_file($path);
        return $sub-&gt;filename eq $path
            &amp;&amp; $sub-&gt;status == Apache2::Const::HTTP_OK;
};</pre>
</div>
</div>
</li>
</ul>
</div>
</div>
<div class="sect2">
<h3 id="_per_repository_gitweb_configuration">Per-repository gitweb configuration</h3>
<div class="paragraph">
<p>You can configure individual repositories shown in gitweb by creating file
in the <code>GIT_DIR</code> of Git repository, or by setting some repo configuration
variable (in <code>GIT_DIR/config</code>, see <a href="git-config.html">git-config(1)</a>).</p>
</div>
<div class="paragraph">
<p>You can use the following files in repository:</p>
</div>
<div class="dlist">
<dl>
<dt class="hdlist1">README.html</dt>
<dd>
<p>A html file (HTML fragment) which is included on the gitweb project
"summary" page inside <em>&lt;div&gt;</em> block element. You can use it for longer
description of a project, to provide links (for example to project&#8217;s
homepage), etc. This is recognized only if XSS prevention is off
(<code>$prevent_xss</code> is false, see <a href="gitweb.conf.html">gitweb.conf(5)</a>); a way to include
a README safely when XSS prevention is on may be worked out in the
future.</p>
</dd>
<dt class="hdlist1">description (or <code>gitweb.description</code>)</dt>
<dd>
<p>Short (shortened to <code>$projects_list_description_width</code> in the projects
list page, which is 25 characters by default; see
<a href="gitweb.conf.html">gitweb.conf(5)</a>) single line description of a project (of a
repository).  Plain text file; HTML will be escaped.  By default set to</p>
<div class="listingblock">
<div class="content">
<pre>Unnamed repository; edit this file to name it for gitweb.</pre>
</div>
</div>
<div class="paragraph">
<p>from the template during repository creation, usually installed in
<code>/usr/share/git-core/templates/</code>.  You can use the <code>gitweb.description</code> repo
configuration variable, but the file takes precedence.</p>
</div>
</dd>
<dt class="hdlist1">category (or <code>gitweb.category</code>)</dt>
<dd>
<p>Single line category of a project, used to group projects if
<code>$projects_list_group_categories</code> is enabled.  By default (file and
configuration variable absent), uncategorized projects are put in the
<code>$project_list_default_category</code> category.  You can use the

<h3 id="_single_url_for_gitweb_and_for_fetching">Single URL for gitweb and for fetching</h3>
<div class="paragraph">
<p>If you want to have one URL for both gitweb and your <code>http://</code>
repositories, you can configure Apache like this:</p>
</div>
<div class="listingblock">
<div class="content">
<pre>&lt;VirtualHost *:80&gt;
    ServerName    git.example.org
    DocumentRoot  /pub/git
    SetEnv        GITWEB_CONFIG   /etc/gitweb.conf

    # turning on mod rewrite
    RewriteEngine on

    # make the front page an internal rewrite to the gitweb script
    RewriteRule ^/$  /cgi-bin/gitweb.cgi

    # make access for "dumb clients" work
    RewriteRule ^/(.*\.git/(?!/?(HEAD|info|objects|refs)).*)?$ \
                /cgi-bin/gitweb.cgi%{REQUEST_URI}  [L,PT]
&lt;/VirtualHost&gt;</pre>
</div>
</div>
<div class="paragraph">
<p>The above configuration expects your public repositories to live under
<code>/pub/git</code> and will serve them as <code>http://git.domain.org/dir-under-pub-git</code>,
both as clonable Git URL and as browsable gitweb interface.  If you then
start your <a href="git-daemon.html">git-daemon(1)</a> with <code>--base-path=/pub/git</code> <code>--export-all</code>
then you can even use the <code>git://</code> URL with exactly the same path.</p>
</div>
<div class="paragraph">
<p>Setting the environment variable <code>GITWEB_CONFIG</code> will tell gitweb to use the
named file (i.e. in this example <code>/etc/gitweb.conf</code>) as a configuration for
gitweb.  You don&#8217;t really need it in above example; it is required only if
your configuration file is in different place than built-in (during
compiling gitweb) <em>gitweb_config.perl</em> or <code>/etc/gitweb.conf</code>.  See
<a href="gitweb.conf.html">gitweb.conf(5)</a> for details, especially information about precedence
rules.</p>
</div>
<div class="paragraph">
<p>If you use the rewrite rules from the example you <strong>might</strong> also need
