+cgit - CGI for Git
+==================
- cgit - cgi for git
+This is an attempt to create a fast web interface for the Git SCM, using a
+built-in cache to decrease server I/O pressure.
+Installation
+------------
-This is an attempt to create a fast web interface for the git scm, using a
-builtin cache to decrease server io-pressure.
+Building cgit involves building a proper version of Git. How to do this
+depends on how you obtained the cgit sources:
+a) If you're working in a cloned cgit repository, you first need to
+initialize and update the Git submodule:
-Installation
+ $ git submodule init # register the Git submodule in .git/config
+ $ $EDITOR .git/config # if you want to specify a different url for git
+ $ git submodule update # clone/fetch and checkout correct git version
- $ make gitsrc=<path>
- $ su
- $ make prefix=<path> install
+b) If you're building from a cgit tarball, you can download a proper git
+version like this:
+ $ make get-git
-Default value for gitsrc is "../git", and this directory should contain the
-git sources.
+When either a) or b) has been performed, you can build and install cgit like
+this:
-Default value for prefix is "/var/www/htdocs/cgit". This directory will
-contain "cgit.cgi" and "cgit.css" after 'make install'.
+ $ make
+ $ sudo make install
-After installation, httpd.conf probably must be updated with a Directory-
-section for cgit, possibly something like this:
+This will install `cgit.cgi` and `cgit.css` into `/var/www/htdocs/cgit`. You
+can configure this location (and a few other things) by providing a `cgit.conf`
+file (see the Makefile for details).
- <Directory "/var/www/htdocs/cgit/">
- AllowOverride None
- Options ExecCGI
- Order allow,deny
- Allow from all
- </Directory>
+If you'd like to compile without Lua support, you may use:
+ $ make NO_LUA=1
-Runtime configuration
+And if you'd like to specify a Lua implementation, you may use:
+
+ $ make LUA_PKGCONFIG=lua5.1
+
+If this is not specified, the Lua implementation will be auto-detected,
+preferring LuaJIT if many are present. Acceptable values are generally "lua",
+"luajit", "lua5.1", and "lua5.2".
+
+
+Dependencies
+------------
+
+* libzip
+* libcrypto (OpenSSL)
+* libssl (OpenSSL)
+* optional: luajit or lua, most reliably used when pkg-config is available
-The file /etc/cgitrc is read by cgit before handling a request. In addition
-to runtime parameters, this file also contains a list of the repositories
-displayed by cgit.
+Apache configuration
+--------------------
-A template cgitrc is shipped with the sources, and all parameters and default
-values are documented in this file.
+A new `Directory` section must probably be added for cgit, possibly something
+like this:
+ <Directory "/var/www/htdocs/cgit/">
+ AllowOverride None
+ Options +ExecCGI
+ Order allow,deny
+ Allow from all
+ </Directory>
