NAME

CPAN::Search::Lite::Util - export some common data structures used by CPAN::Search::Lite::*

DESCRIPTION

This module exports some common data structures used by other CPAN::Search::Lite::* modules. At present these are

• %chaps

  This is hash whose keys are the CPAN chapter ids with associated values being the corresponding chapter descriptions.

• %chaps_rev

  This is the reverse hash of %chaps.

• $repositories

  This is a hash reference whose keys are repository ids. The associated values are hash references whose keys are

  alias - an alias for the repository.

  LOCATION - the url of the repository.

  SUMMARYFILE - a file on the repository to fetch when requesting a repository summary.

  browse - a url by which one can browse the contents of a repository.

  desc - a repostitory description

  build - the ActivePerl build number appropriate for the repository (eg, 6xx, for Perl 5.6, and8xx, for 5.8).

  PerlV - the Perl version that the repository supports.

• $table_id

  This is a hash reference whose keys are the tables used and whose values are the associated primary keys.

• $full_id

  This is a hash reference whose keys are the primary keys of the tables and whose values are the associated fully qualified primary keys (ie, with the table name prepended).

• $mode_info

  This is a hash reference whose keys are the allowed modes of CPAN::Search::Lite::Query and whose associated values are hash references with keys id, name, and text describing what columns to use for that key.

• $query_info

  This is a hash reference whose purpose is to provide shortcuts to making queries using CPAN::Search::Lite::Query. The keys of this reference is the shortcut name, and the associated value is a hash reference specifying the required mode and type keys.

• $tt2_pages

  This is a hash reference whose keys are the modes used in CPAN::Search::Lite::Query and whose values are hash references (with keys search, info, and letter) specifying what Template-Toolkit page to use for the specific result.

• vcmp

  This routine, used as

  if (vcmp($v1, $v2) > 0) {
    print "$v1 is higher than $v2\n";
  }

  is used to compare two versions, and returns 1/0/-1 if the first argument is considered higher/equal/lower than the second. It uses Sort::Versions.
