NAME

URI::VersionRange - Perl extension for VERS (Version Range Specifier)

SYNOPSIS

  use URI::VersionRange;
  # OO-interface
  $vers = URI::VersionRange->new(
    scheme      => 'cpan',
    constraints => ['>2.00']
  );
  
  say $vers; # vers:cpan/>2.00
  if ($vers->contains('2.10')) {
    say "The version is in range";
  }
  # Parse "vers" string
  $vers = URI::VersionRange->from_string('vers:cpan/>2.00|<2.25');
  # exported functions
  $vers = decode_vers('vers:cpan/>2.00|<2.25');
  say $vers->scheme;  # cpan
  $vers_string = encode_vers(scheme => cpan, constraints => ['>2.00']);
  say $vers_string; # vers:cpan/>2.00
  # alias
  $vers = VERS->new(
    scheme      => 'cpan',
    constraints => ['>2.00']
  );
  $vers = VERS->from_string('vers:cpan/>2.00|<2.25');

DESCRIPTION

A version range specifier (VERS) is a URI string using the "vers" URI-scheme with this syntax:

  vers:<versioning-scheme>/<version-constraint>|<version-constraint>|...

"vers" is the URI-scheme and is an acronym for "VErsion Range Specifier".

The pipe "|" is used as a simple separator between "version-constraint". Each "version-constraint" in this pipe-separated list contains a comparator and a version:

  <comparator:version>

This list of "version-constraint" are signposts in the version timeline of a package that specify version intervals.

A "version" satisfies a version range specifier if it is contained within any of the intervals defined by these "version-constraint".

FUNCTIONAL INTERFACE

They are exported by default:

encode_vers

    $vers_string = encode_vers(%params);

Converts the given "vers" components to "vers" string. Croaks on error.

This function call is functionally identical to:

    $vers_string = URI::VersionRange->new(%params)->to_string;

decode_vers

    $vers = decode_vers($vers_string);

Converts the given "vers" string to URI::VersionRange object. Croaks on error.

This function call is functionally identical to:

    $vers = URI::VersionRange->from_string($vers_string);

OBJECT-ORIENTED INTERFACE

new

    $vers = URI::VersionRange->new( scheme => STRING, constraints => ARRAY )
    $vers = VERS->new( scheme => STRING, constraints => ARRAY )

Create new URI::VersionRange instance using provided VERS components (scheme, constraints).

scheme

    $vers->scheme

By convention the versioning scheme should be the same as the URI::PackageURL package "type" for a given package ecosystem.

constraints

    $vers->constraints

"constraints" is ARRAY of URI::VersionRange::Constraint object.

contains

    $vers->contains($version)

Check if a version is contained within a range

    my $vers = URI::VersionRange::from_string('vers:cpan/>2.00|<2.25');
    if ($vers->contains('2.10')) {
        say "The version is in range";
    }

See URI::VersionRange::Version.

constraint_contains

    $vers->constraint_contains

Check if a version is contained within a specific constraint.

See URI::VersionRange::Version.

to_hash

    $vers->to_hash

Turn VERS components into a hash reference.

to_string

    $vers->to_string

Stringify VERS components.

TO_JSON

    $vers->TO_JSON

Helper method for JSON modules (JSON, JSON::PP, JSON::XS, Mojo::JSON, etc).

    use Mojo::JSON qw(encode_json);
    say encode_json($vers);
    # {
    #   "constraints": [
    #     {
    #       "comparator": ">",
    #       "version": "2.00"
    #     },
    #     {
    #       "comparator": "<",
    #       "version": "2.25"
    #     }
    #   ],
    #   "scheme": "cpan"
    # }

from_string

    $vers = URI::VersionRange->from_string($vers_string);
    $vers = VERS->from_string($vers_string);

Converts the given "vers" string to VERS components and return URI::VersionRange instance. Croaks on error.

from_native

Converts the specified native range string using "native_range_to_vers" and returns and return URI::VersionRange instance.

    $vers = URI::VersionRange->from_native('npm', '~1.6.5 || >=1.7.2');

Supported native range scheme:

For other schemes, "native_range_to_vers" will attempt to convert the native range string to a VERS string, but this may not work perfectly.
