DESCRIPTION

This class holds one copyright statement, i.e. year range, name and email of one copyright contributor.

On construction, a cleanup is done to make the statement more standard. Here are some cleanup example:

 2002-6 Joe => 2002-2006, Joe
 2001,2002,2003,2004 Joe => 2001-2004, Joe
 # found in markdown documents
 2002 Joe mailto:joe@example.com => 2002, Joe <joe@example.com>

CONSTRUCTOR

The constructor can be called without argument or with a string containing:

  • a year range (optional)

  • a name (mandatory)

  • an email address (optional)

E.g:

 my $st = Software::Copyright::Statement->new();
 my $st = Software::Copyright::Statement->new('2002, Joe <joe@example.com>');

Methods

name

Set or get owner's name

email

Set or get owner's name

owner

This method returns $self

add_years

Add a year range to the copyright owner. This method accepts year ranges like "2020", "2018, 2020", "2016-2020,2022". White spaces are ignored.

This method returns $self

stringify

Returns a string containing a year range (if any), a name and email (if any) of the copyright owner.

contains

Return 1 if the other statement is contained in current statement, i.e. owner or record are identical and other year range is contained in current year range.

For instance:

  • 2016, Joe is contained in 2014-2020, Joe

  • 2010, Joe is not contained in 2014-2020, Joe

Operator overload
