# CPAN::DistnameInfo(3pm)

Extract distribution name and version from a distribution filename

## NAME

CPAN::DistnameInfo - Extract distribution name and version from a distribution filename

## SYNOPSIS

```
  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

- cpanid

  If the path given looked like a CPAN authors directory path, then this will be the the CPAN id of the author.

- dist

  The name of the distribution

- distvname

  The file name with any suffix and leading directory names removed

- filename

  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.

- maturity

  The maturity of the distribution. This will be either `"released"` or `"developer"`

- extension

  The extension of the distribution, often used to denote the archive type (e.g. 'tar.gz')

- pathname

  The pathname that was passed to the constructor when creating the object.

- properties

  This will return a list of key-value pairs, suitable for assigning to a hash, for the known properties.

- version

  The extracted version
