DEVELOPERS

For you wacky developers, I've provided access to the raw command data via the _raw_commands method. The underbar at the beginning should let you know that this is an experimental interface for developers only.

_raw_commands returns a hash reference. The keys of this hash are the command names. The values are a hash of data about the command. This hash contains the following data:

  • short_help

    Short help text

  • help

    Long help text

  • cmd

    Code reference for the command. This command requires that a hash be passed to it containing an api parameter, which is a POE::API::Peek object, and an args parameter, which is an array reference of arguments (think @ARGV).
