NAME CPAN::02Packages::Search - Search packages in 02packages.details.txt SYNOPSIS use CPAN::02Packages::Search; my $index = CPAN::02Packages::Search->new(file => '/path/to/02packages.details.txt'); my $result1 = $index->search('Plack'); # { version => "1.0048", path => "M/MI/MIYAGAWA/Plack-1.0048.tar.gz" } my $result2 = $index->search('Does_Not_Exist'); # undef DESCRIPTION CPAN::02Packages::Search allows you to search packages in the de facto standard CPAN index file 02packages.details.txt. MOTIVATION We can already search packages in 02packages.details.txt by the excellent module CPAN::Common::Index::Mirror. Its functionality is not only searching packages, but also searching authors and even fetching/caching index files. As an author of CPAN clients, I just want to search packages in 02packages.details.txt. So I ended up extracting functionality of searching packages from CPAN::Common::Index::Mirror as CPAN::02Packages::Search. PERFORMANCE CPAN::Common::Index::Mirror and CPAN::02Packages::Search use Search::Dict, which implements binary search. A simple benchmark shows that CPAN::02Packages::Search is 422 times faster than naive search. ❯ perl bench/bench.pl Rate naive_search our_search naive_search 4.13/s -- -100% our_search 1752/s 42291% -- See bench/bench.pl for details.
