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

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.
