License::Software - provides templated software licenses
use License::Software; my $author = 'Max Musterman'; my $license = License::Software.get('gpl').new($author); say $license.name; # Full license name say $license.short-name; # Short name like 'GPLv3' say $license.alias; # List of license alias say $license.url; # License url say $license.header; # License header ⋮ # ⋮ =output The GNU General Public License, Version 3, 29 June 2007
Applying a license to your software is not an easy task. Different licenses dictate different usage and formatting rules. A prime example of a “complicated” license is the GNU General Public License (https://www.gnu.org/licenses/gpl.txt) and the GNU Lesser General Public License (https://www.gnu.org/licenses/lgpl.txt).
The License::Software provides a common interface for querying the software license templates for data. Software licenses and their usage practices differ greatly, but they have a number of common properties:
One or multiple copyright holders (authors).
Copyright notice per holder
Year or year range (i.e: 2000-2010) per holder
Copying permission, stating under which terms the software is distributed
Header to be added at the beginning of each licensed file
Minor things, like url, short-name, name aliases or how dates are formatted
Currently this module provides the following licenses:

Getting the license class
Return all supported licenses.
sub get(Str:D $alias)
Return the software license class for the given alias. I.e alias for the General Public License 3 are 'GPLv3', 'GPL3' & 'GPL'.
sub from-url(Str:D $url)
Return the software license class for the given url. I.e http://www.apache.org/licenses/LICENSE-2.0 is the url for Apache2 license.
License class methods
multi new(Str:D $name, $year?)
Expects a copyright holder name and an optional year. The license will use 'This program' as
multi method new(Str:D $works-name, %h) multi method new(%h)
%h is a hash where keys are the copyright holders names and values the copyright year. If no
$works-name is provided it uses 'This program' by default.
method header returns Str:D
Str which should be added to each licensed file (source code) at the top. I.e. GPL expects to have “This program is free software: you can redistribute it and/or modify…” header at the top of each file.
method files returns Hash:D
Hash where keys are file names and the value the file contents. This is useful for licenses which dictate to have multiple different files. I.e. Apache2 generates a 'LICENSE' and a 'NOTICE' file.
method full-text returns Str:D
Returns the full text of the license.
method name returns Str:D
Returns the full license name as
Str. I.e. for GPLv3 this would be “The GNU General Public License, Version 3, 29 June 2007”
method short-name returns Str:D
Returns the short name for a license. I.e. 'GPLv3'.
method note returns Str:D
Returns a short license text which can be used in README and Co.
submethod aliases returns Array[Str]
Returns all known alias' for the license.
submethod url returns Str:D
Returns the license url.
