NAME¶CPAN::DistnameInfo - Extract distribution name and version from a distribution filename
my $pathname = "authors/id/G/GB/GBARR/CPAN-DistnameInfo-0.02.tar.gz"; my $d = CPAN::DistnameInfo->new($pathname); my $dist = $d->dist; # "CPAN-DistnameInfo" my $version = $d->version; # "0.02" my $maturity = $d->maturity; # "released" my $filename = $d->filename; # "CPAN-DistnameInfo-0.02.tar.gz" my $cpanid = $d->cpanid; # "GBARR" my $distvname = $d->distvname; # "CPAN-DistnameInfo-0.02" my $extension = $d->extension; # "tar.gz" my $pathname = $d->pathname; # "authors/id/G/GB/GBARR/..." my %prop = $d->properties;
DESCRIPTION¶Many online services that are centered around CPAN attempt to associate multiple uploads by extracting a distribution name from the filename of the upload. For most distributions this is easy as they have used ExtUtils::MakeMaker or Module::Build to create the distribution, which results in a uniform name. But sadly not all uploads are created in this way.
"CPAN::DistnameInfo" uses heuristics that have been learnt by <http://search.cpan.org/> to extract the distribution name and version from filenames and also report if the version is to be treated as a developer release
The constructor takes a single pathname, returning an object with the following methods
- If the path given looked like a CPAN authors directory path, then this will be the the CPAN id of the author.
- The name of the distribution
- The file name with any suffix and leading directory names removed
- If the path given looked like a CPAN authors directory path, then this will be the path to the file relative to the detected CPAN author directory. Otherwise it is the path that was passed in.
- The maturity of the distribution. This will be either "released" or "developer"
- The extension of the distribution, often used to denote the archive type (e.g. 'tar.gz')
- The pathname that was passed to the constructor when creating the object.
- This will return a list of key-value pairs, suitable for assigning to a hash, for the known properties.
- The extracted version
