NAME

Software::License::Custom - custom license handler

VERSION

version 0.103014

DESCRIPTION

This module extends Software::License to give the possibility of specifying all aspects related to a software license in a custom file. This allows for setting custom dates, notices, etc. while still preserving compatibility with all places where Software::License is used, e.g. Dist::Zilla.

In this way, you should be able to customise some aspects of the licensing messages that would otherwise be difficult to tinker, e.g. adding a note in the notice, setting multiple years for the copyright notice or set multiple authors and/or copyright holders.

The license details should be put inside a file that contains different sections. Each section has the following format:

This is a line that begins and ends with two underscores "__". The string between the begin and the end of the line is first depured of any non-word character, then used as the name of the section;
a Text::Template (possibly a plain text file) where items to be expanded are enclosed between double braces

Each section is terminated by the header of the following section or by the end of the file. Example:

   __[ NAME ]__
   The Foo-Bar License
   __URL__
   http://www.example.com/foo-bar.txt
   __[ META_NAME ]__
   foo_bar_meta
   __{ META2_NAME }__
   foo_bar_meta2
   __{ SPDX_EXPRESSION }__
   foo_bar_spdx_expression
   __[ NOTICE ]__
   Copyright (C) 2000-2002 by P.R. Evious
   Copyright (C) {{$self->year}} by {{$self->holder}}.
   This is free software, licensed under {{$self->name}}.
   __[ LICENSE ]__
               The Foo-Bar License
   Well... this is only some sample text.  Verily... only sample text!!!
   Yes, spanning more lines and more paragraphs.

The different formats for specifying the section name in the example above are only examples, you're invited to use a consistent approach.

METHODS

new

   my $slc = Software::License::Custom->new({filename => 'LEGAL'});

Create a new object. Arguments are passed through an anonymous hash, the following keys are allowed:

  filename - the file where the custom software license details are stored

load_sections_from

   $slc->load_sections_from('MY-LEGAL-ASPECTS');

Loads the different sections of the license from the provided filename.

Returns the input object.

section_data

   my $notice_template_reference = $slc->section_data('NOTICE');

Returns a reference to a textual template that can be fed to Text::Template (it could be simple text), according to what is currently loaded in the object.

MORE METHODS

The following methods, found in all software license classes, look up and render the template with the capitalized form of their name. In other words, the "license" method looks in the "LICENSE" template.

For now, the "meta_name" and "meta2_name" methods return "custom" if called on the class. This may become fatal in the future.

  • name
  • url
  • meta_name
  • meta2_name
  • license
  • notice
  • fulltext
  • version
