CPAN::Distroprefs -- read and match distroprefs SYNOPSIS
use CPAN::Distroprefs; my %info = (... distribution/environment info ...); my $finder = CPAN::Distroprefs->find($prefs_dir, \%ext_map); while (my $result = $finder->next) { die $result->as_string if $result->is_fatal; warn($result->as_string), next if $result->is_warning; for my $pref (@{ $result->prefs }) { if ($pref->matches(\%info)) { return $pref; } } } DESCRIPTION
This module encapsulates reading Distroprefs and matching them against CPAN distributions. INTERFACE
my $finder = CPAN::Distroprefs->find($dir, \%ext_map); while (my $result = $finder->next) { ... } Build an iterator which finds distroprefs files in the given directory. %ext_map is a hashref whose keys are file extensions and whose values are modules used to load matching files: { 'yml' => 'YAML::Syck', 'dd' => 'Data::Dumper', ... } Each time "$finder->next" is called, the iterator returns one of two possible values: o a CPAN::Distroprefs::Result object o "undef", indicating that no prefs files remain to be found RESULTS
"find()" returns CPAN::Distroprefs::Result objects to indicate success or failure when reading a prefs file. Common All results share some common attributes: type "success", "warning", or "fatal" file the file from which these prefs were read, or to which this error refers (relative filename) ext the file's extension, which determines how to load it dir the directory the file was read from abs the absolute path to the file Errors Error results (warning and fatal) contain: msg the error message (usually either $! or a YAML error) Successes Success results contain: prefs an arrayref of CPAN::Distroprefs::Pref objects PREFS
CPAN::Distroprefs::Pref objects represent individual distroprefs documents. They are constructed automatically as part of "success" results from "find()". data the pref information as a hashref, suitable for e.g. passing to Kwalify match_attributes returns a list of the valid match attributes (see the Distroprefs section in CPAN) currently: "env perl perlconfig distribution module" has_any_match true if this pref has a 'match' attribute at all has_valid_subkeys true if this pref has a 'match' attribute and at least one valid match attribute matches if ($pref->matches(\%arg)) { ... } true if this pref matches the passed-in hashref, which must have a value for each of the "match_attributes" (above) LICENSE

CPAN::Meta::YAML - Read and write a subset of YAML for CPAN Meta files VERSION
version 0.008 SYNOPSIS
use CPAN::Meta::YAML; # reading a META file open $fh, "<:utf8", "META.yml"; $yaml_text = do { local $/; <$fh> }; $yaml = CPAN::Meta::YAML->read_string($yaml_text) or die CPAN::Meta::YAML->errstr; # finding the metadata $meta = $yaml->[0]; # writing a META file $yaml_text = $yaml->write_string or die CPAN::Meta::YAML->errstr; open $fh, ">:utf8", "META.yml"; print $fh $yaml_text; DESCRIPTION
This module implements a subset of the YAML specification for use in reading and writing CPAN metadata files like META.yml and MYMETA.yml. It should not be used for any other general YAML parsing or generation task. NOTE: META.yml (and MYMETA.yml) files should be UTF-8 encoded. Users are responsible for proper encoding and decoding. In particular, the "read" and "write" methods do not support UTF-8 and should not be used. SUPPORT
This module is currently derived from YAML::Tiny by Adam Kennedy. If there are bugs in how it parses a particular META.yml file, please file a bug report in the YAML::Tiny bugtracker: <> SEE ALSO
