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 ftp://ftp.funet.fi/pub/CPAN/.

socket

This is the socket that FCGI should listen on for requests. It is a mandatory requirement for the cpanidx-fcgi script.

skipcore

Applicable to the cpanidx-gendb script, will skip the generation of the Module::CoreList based tables.

skipmirrors

Applicable to the cpanidx-gendb script, will skip the generation of the mirrorlist based tables.

skipperms

Applicable to the cpanidx-gendb script, will skip the generation of the CPAN permissions based tables.

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/<prefix>/<format>/<cmd>/<search_term>

We will assume that <prefix> is cpanidx for the purposes of this documentation.

<format>

The format may be one of yaml, json, xml or html.

<cmd>

The command may be one of the following:

mod

Takes a search term which is a module name to search for. Returns information relating to that module if it exists.
