NAME

String::License - detect source code license statements in a text string

VERSION

Version v0.0.2

SYNOPSIS

use String::License;
use String::License::Naming::Custom;

my $string = 'Licensed under same terms as Perl itself';

my $expressed  = String::License->new( string => $string );
my $expression = $expressed->as_text;  # => "Perl"

my $desc        = String::License::Naming::Custom->new;
my $described   = String::License->new( string => $string, naming => $desc );
my $description = $described->as_text;  # => "The Perl 5 License"

DESCRIPTION

String::License identifies license statements in a string and serializes them in a normalized format.

CONSTRUCTOR

new

my $licensed = String::License->new( string => 'Licensed under GPLv2' );

Accepts named arguments, and constructs and returns a String::License object.

The following options are recognized:

string => STRING

The scalar string to parse for licensing information.

naming => OBJ

A String::License::Naming object, used to define license naming conventions.

By default uses String::License::Naming::SPDX.

Since instantiation of naming schemes is expensive, there can be a significant speed boost in passing a pre-initialized naming object when processing multiple strings.

METHODS

as_text

Returns identified licensing patterns as a string, either structured as SPDX License Expressions, or with scheme-less naming as a short description.
