Identity::Utils - Provide utility functions related to distribution identities


code

=begin code :lang<raku>

use Identity::Utils;

my $identity = "Foo::Bar:ver<0.0.42>:auth<zef:lizmat>:api<2.0>";

say short-name($identity);  # Foo::Bar

say ver($identity);         # 0.0.42

say version($identity);     # v0.0.42

say auth($identity);        # zef:lizmat

say ecosystem($identity);   # zef

say nick($identity);        # lizmat

say api($identity);         # 2.0

=end code


Identity::Utils provides some utility functions for inspecting various aspects
of distribution identity strings.  They assume any given string is a
well-formed identity in the form C<name:ver<0.0.1>:auth<eco:nick>> with an
optional C<api:<1>> field.


=begin code :lang<raku>

my $identity = "Foo::Bar:ver<0.0.42>:auth<zef:lizmat>:api<2.0>";
say api($identity); # 2.0

=end code


Returns the C<api> field of the given identity, or C<Nil> if no C<api> field
could be found.


=begin code :lang<raku>

my $identity = "Foo::Bar:ver<0.0.42>:auth<zef:lizmat>:api<2.0>";
say auth($identity); # zef:lizmat

=end code


Returns the C<auth> field of the given identity, or C<Nil> if no C<auth> field
could be found.


=begin code :lang<raku>

my $identity = "Foo::Bar:ver<0.0.42>:auth<zef:lizmat>:api<2.0>";
say ecosystem($identity); # zef

=end code


Returns the ecosystem part of the C<auth> field of the given identity, or
C<Nil> if no C<auth> field could be found.


=begin code :lang<raku>

my $identity = "Foo::Bar:ver<0.0.42>:auth<zef:lizmat>:api<2.0>";
say nick($identity); # lizmat

=end code


Returns the nickname part of the C<auth> field of the given identity, or
C<Nil> if no C<auth> field could be found.


=begin code :lang<raku>

my $identity = "Foo::Bar:ver<0.0.42>:auth<zef:lizmat>:api<2.0>";
say short-name($identity);  # Foo::Bar

=end code


Returns the short name part of the given identity, or the identity itself
if no C<ver>, C<auth> or C<api> fields could be found.


=begin code :lang<raku>

my $identity = "Foo::Bar:ver<0.0.42>:auth<zef:lizmat>:api<2.0>";
say ver($identity);  # 0.0.42

=end code


Returns the C<ver> field of the given identity as a C<Str>, or C<Nil> if no
C<ver> field could be found.


=begin code :lang<raku>

my $identity = "Foo::Bar:ver<0.0.42>:auth<zef:lizmat>:api<2.0>";
say version($identity);  # v0.0.42

=end code


Returns the C<ver> field of the given identity as a C<Version> object, or
C<Nil> if no C<ver> field could be found.
