 756 <div class="sectionbody">
 757 <div class="paragraph"><p>The gitweb CGI script for viewing Git repositories over the web uses a
 758 perl script fragment as its configuration file.  You can set variables
 759 using "<code>our $variable = value</code>"; text from a "#" character until the
 760 end of a line is ignored.  See <strong>perlsyn</strong>(1) for details.</p></div>
 761 <div class="paragraph"><p>An example:</p></div>

 763 <div class="content">
 764 <pre><code># gitweb configuration file for http://git.example.org

 766 our $projectroot = "/srv/git"; # FHS recommendation
 767 our $site_name = 'Example.org &gt;&gt; Repos';</code></pre>
 768 </div></div>
 769 <div class="paragraph"><p>The configuration file is used to override the default settings that
 770 were built into gitweb at the time the <em>gitweb.cgi</em> script was generated.</p></div>
 771 <div class="paragraph"><p>While one could just alter the configuration settings in the gitweb
 772 CGI itself, those changes would be lost upon upgrade.  Configuration
 773 settings might also be placed into a file in the same directory as the
 774 CGI script with the default name <em>gitweb_config.perl</em>&#8201;&#8212;&#8201;allowing
 775 one to have multiple gitweb instances with different configurations by
 776 the use of symlinks.</p></div>
 777 <div class="paragraph"><p>Note that some configuration can be controlled on per-repository rather than
 778 gitweb-wide basis: see "Per-repository gitweb configuration" subsection on
 779 <a href="gitweb.html">gitweb(1)</a> manpage.</p></div>

 781 </div>
 782 <div class="sect1">
 783 <h2 id="_discussion">DISCUSSION</h2>
 784 <div class="sectionbody">
 785 <div class="paragraph"><p>Gitweb reads configuration data from the following sources in the
 786 following order:</p></div>
 787 <div class="ulist"><ul>
 788 <li>
 789 <p>
 790 built-in values (some set during build stage),
 791 </p>
 792 </li>
 793 <li>
 794 <p>
 795 common system-wide configuration file (defaults to
 796    <code>/etc/gitweb-common.conf</code>),
 797 </p>
 798 </li>
 799 <li>
 800 <p>
 801 either per-instance configuration file (defaults to <em>gitweb_config.perl</em>
 802    in the same directory as the installed gitweb), or if it does not exist
 803    then fallback system-wide configuration file (defaults to <code>/etc/gitweb.conf</code>).
 804 </p>
 805 </li>
 806 </ul></div>
 807 <div class="paragraph"><p>Values obtained in later configuration files override values obtained earlier
 808 in the above sequence.</p></div>
 809 <div class="paragraph"><p>Locations of the common system-wide configuration file, the fallback
 810 system-wide configuration file and the per-instance configuration file
 811 are defined at compile time using build-time Makefile configuration
 812 variables, respectively <code>GITWEB_CONFIG_COMMON</code>, <code>GITWEB_CONFIG_SYSTEM</code>
 813 and <code>GITWEB_CONFIG</code>.</p></div>
 814 <div class="paragraph"><p>You can also override locations of gitweb configuration files during
 815 runtime by setting the following environment variables:
 816 <code>GITWEB_CONFIG_COMMON</code>, <code>GITWEB_CONFIG_SYSTEM</code> and <code>GITWEB_CONFIG</code>
 817 to a non-empty value.</p></div>
 818 <div class="paragraph"><p>The syntax of the configuration files is that of Perl, since these files are
 819 handled by sourcing them as fragments of Perl code (the language that
 820 gitweb itself is written in). Variables are typically set using the
 821 <code>our</code> qualifier (as in "<code>our $variable = &lt;value&gt;;</code>") to avoid syntax
 822 errors if a new version of gitweb no longer uses a variable and therefore
 823 stops declaring it.</p></div>
 824 <div class="paragraph"><p>You can include other configuration file using read_config_file()
 825 subroutine.  For example, one might want to put gitweb configuration
 826 related to access control for viewing repositories via Gitolite (one
 827 of Git repository management tools) in a separate file, e.g. in
 828 <code>/etc/gitweb-gitolite.conf</code>.  To include it, put</p></div>
 829 <div class="listingblock">
 830 <div class="content">
 831 <pre><code>read_config_file("/etc/gitweb-gitolite.conf");</code></pre>
 832 </div></div>
 833 <div class="paragraph"><p>somewhere in gitweb configuration file used, e.g. in per-installation
 834 gitweb configuration file.  Note that read_config_file() checks itself
 835 that the file it reads exists, and does nothing if it is not found.
 836 It also handles errors in included file.</p></div>
 837 <div class="paragraph"><p>The default configuration with no configuration file at all may work
 838 perfectly well for some installations.  Still, a configuration file is
 839 useful for customizing or tweaking the behavior of gitweb in many ways, and
 840 some optional features will not be present unless explicitly enabled using
 841 the configurable <code>%features</code> variable (see also "Configuring gitweb
 842 features" section below).</p></div>

 850 in their description.  See gitweb&#8217;s <em>INSTALL</em> file for instructions on building

 941         This subroutine should take one parameter, the full path to
 942         a project, and if it returns true, that project will be included
 943         in the projects list and can be accessed through gitweb as long
 944         as it fulfills the other requirements described by $export_ok,

 966         This for example makes <code>$export_ok</code> file decide if repository is

 970         <code>GITWEB_STRICT_EXPORT</code>.  By default this variable is not set, which
 971         means that you can directly access those repositories that are hidden

1027 detection.  The first and second priority are <code>%highlight_basename</code> and
1028 <code>%highlight_ext</code>, which detect based on basename (the full filename, for
1029 example "Makefile") and extension (for example "sh").  The keys of these
1030 hashes are the basename and extension, respectively, and the value for a
1031 given key is the name of the syntax to be passed via <code>--syntax &lt;syntax&gt;</code>
1032 to "highlight".  The last priority is the "highlight" configuration of
1033 <code>Shebang</code> regular expressions to detect the language based on the first
1034 line in the file, (for example, matching the line "#!/bin/bash").  See
1035 the highlight documentation and the default config at
