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:
- conan
- gem
- nginx
- npm
- nuget
- raku
- semver
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.
