NAME

Version::Raku - Version with comparator methods

SYNOPSIS

use Version::Raku;

my $left  = Version::Raku.new("1.0");
my $right = Version::Raku.new("1.1");

say $left.cmp($right);  # Less
say $left."<"($right);  # True

DESCRIPTION

The Version::Raku distribution provides a Version::Raku class that is a sub-class of Version, but which provides a number of comparator methods, similar to the ones provided by the Version::Repology distribution.

INSTANTIATION

my $v = Version::Raku.new("1.0");

The basic instantion of a Version::Raku object is done with the new method, taking the version string as a positional argument.

CLASS METHODS

as-generic-range

say Version::Raku.as-generic-range(v1.2);     # (== v1.2)
say Version::Raku.as-generic-range(v1.2+);    # (>= v1.2)
say Version::Raku.as-generic-range('1.2.*');  # (>= v1.2 < v1.3)

Convert a Raku version specification to a generic range specification, consisting of a Slip with a string representing a comparator ("==", ">=", "<") and a Version::Raku object, possibly repeated.

COMPARATOR METHODS

cmp

my $left  = Version::Raku.new("1.0");
my $right = Version::Raku.new("1.1");

say $left.cmp($left);   # Same
say $left.cmp($right);  # Less
say $right.cmp($left);  # More

The cmp method returns the Order of a comparison of the invocant and the positional argument, which is either Less, Same, or More.

eqv

my $left  = Version::Raku.new("1.01");
my $right = Version::Raku.new("1.1");

say $left.eqv($right);  # True

The eqv method returns whether the internal state of two Version::Raku objects are identical.

== != < <= > >= ~~

my $left  = Version::Raku.new("1.0");
my $right = Version::Raku.new("1.1");

say $left."=="($right);  # False
say $left."<"($right);   # True

These oddly named methods provide the same functionality as their infix counterparts. Please note that you must use the "xx"() syntax, because otherwise the Raku compiler will assume you've made a syntax error.
