NAME App::CPANIDX - Queryable web-based CPAN Index SYNOPSIS # Generate the index database $ cpanidx-gendb --config cpanidx.ini # Run the FastCGI script $ cpanidx-fcgi --config cpanidx.ini DESCRIPTION App::CPANIDX provides a number of scripts to build a queryable web-based CPAN index. CONFIGURATION Configuration is dealt with by a Config::Tiny based configuration file. There are a number of parameters which can be specified "dsn" The DBI dsn string of the database that the scripts will use. This is a mandatory requirement. "user" The username for the supplied "dsn". "pass" The password for the supplied "dsn". "url" The "cpanidx-gendb" script will poll this url when it has finished its update. It should be the root url of your CPANIDX site url=http://my.cpanidx.site/cpanidx/ "mirror" The url of a CPAN mirror site where "cpanidx-gendb" will obtain its index files from. If not supplied it defaults to the Funet site . "socket" This is the socket that FCGI should listen on for requests. It is a mandatory requirement for the "cpanidx-fcgi" script. SCRIPTS Both the scripts will by default look for a "cpanidx.ini" file in the current working directory unless you specify an alternative with the "--config" command line option. "cpanidx-gendb" Generates the CPANIDX database. It will retrieve the CPAN index files from a CPAN mirror and parse them to build the database. The CPAN indexes are downloaded to "~/.cpanidx" by default. You may override this location by setting the "PERL5_CPANIDX_DIR" environment variable to a different location to use. In tests a DBD::SQLite database took over 3 minutes to generate and a DBD::mysql database took 30 seconds. It is recommended that one uses cron or some such scheduler to run this script every hour to ensure freshness of the CPAN index. "cpanidx-fcgi" Presents the CPAN index to web clients via FastCGI. Specify a socket that the script should listen for requests on and configure your webserver accordingly. The following is an example for Lighttpd: fastcgi.server = ( "/cpanidx/" => ( "localhost" => ( "host" => "127.0.0.1", "port" => 1027, "check-local" => "disable", ) ), ) The interface that clients can query is described below. INTERFACE The "cpanidx-fcgi" provides a number of ways that clients can access information from the CPAN Index. The information is provided in a number of different formats: YAML, JSON, XML and HTML. Information is requested by using a special URL http://name.of.website//// We will assume that is "cpanidx" for the purposes of this documentation. " The format may be one of "yaml", "json", "xml" or "html". " The command may be one of the following: "mod" Takes a search term which is a module name to search for.
