NAME¶

Regexp::Pattern::License - Regular expressions for legal licenses

VERSION¶

Version v3.7.1

SYNOPSIS¶

    use Regexp::Pattern::License;
    use Regexp::Pattern;
    my $re     = re( 'License::gpl_3' );
    my $string = 'GNU General Public License version 3 or later';
    $string =~ /$re/; # => success

DESCRIPTION¶

Regexp::Pattern::License provides a hash of regular expression patterns related to legal software licenses.

Regexp::Pattern is a convention for organizing reusable regex patterns.

License combinations¶

Patterns each covering a combination of multiple licenses.

Each of these patterns has the tag type:combo .

net_snmp
perl

License groups¶

Patterns each covering either of multiple licenses.

Each of these patterns has the tag type:group .

bsd
cc
gnu
mit

STRUCTURE¶

The regexp patterns follows the DefHash specification, and more specifically the structure of Regexp::Pattern, defining access to one pattern per DefHash object, as "pat".

Additionally, (sub)patterns are available in plaintext form, as "pat.alt.*".

SUBJECT¶

Each pattern targets one or more subjects, i.e. ways to directly or indirectly represent a license.

Beware that not all pattern objects fully cover all subjects.

trait: Distinguishing trait or feature expressed in licensing strings, e.g. an advertising clause or granting "...or any later version."
Coverage for this subject is currently rather weak.
name: Distinguishing name, e.g. usable in license grant.
grant: Text granting the license.
license: Text containing licensing terms.
Texts containing both license grant and licensing terms (e.g. BSD- and MIT-style licensing) may be classified as either subject grant or subject license. This may change, as needs for distinction is better understood.

SCOPE¶

Each pattern can process material within some scope, i.e. a certain sample size of the full subject.

As an example, <https://codesearch.debian.net/> use line-based processing, where patterns spanning multiple lines are not applicable.

line: Pattern typically found within a single line. Typically this means less than 70 characters within scope.
sentence: Pattern matching within a sentence.
May span multiple lines, but not across multiple sentences. Typically this means no full-stop or colon within scope.
paragraph: Pattern matching distinguishing paragraph.
May span multiple sentences, but not multiple paragraphs. Typically this means no newline within scope.
section: Pattern matching distinguishing section.
May span multiple paragraphs, but not multiple sections. Typically this means blank line within scope.
multisection: Pattern may span multiple sections.

TAGS¶

Pattern defhashes optionally includes tags, which may help in selecting multiple related patterns.

Tags are hierarchical, with ":" as separator, and may be extended without notice. Therefore take care to permit sub-parts when tag-matching, e.g. using a regex like " /\Asome:tag(?:\z|:)/ ".

family:bsd
family:cc
family:gpl
family:mit
family:zlib
Pattern covers a license part of a family of licenses.
license:contains:grant:*
License mentions a preferred form for granting the license.

This implies that license is commonly granted by use of a different (typically far shorter) text.

Fourth part (optional) is the key to corresponding license pattern, for a grant belonging to a different license (when omitted then a grant for same license is assumed).
license:contains:license:*
License contains another license.

Wildcard is the key to corresponding license pattern.
license:contains:name:*
License mentions name of another license.
license:includes:license:*
License references coverage of another license.

Wildcard is the key to corresponding license pattern.
license:is:grant
License is commonly granted by stating the whole license.
license:published:*
License grant may include an "as published by..." reference.

Third part is the key to corresponding trait pattern.
type:trait:publisher:*
Pattern covers an "as published by ..." license grant phrase.

Third part (optional) is the key to corresponding license pattern.
type:usage:*:*
Pattern covers a specific usage of a license.

Third part is the key of the corresponding non-usage-specific pattern.

Fourth part is the key of the corresponding usage trait pattern.
type:combo
Pattern covers a combination of multiple licenses.
type:group
Pattern covers either of multiple licenses.
type:singleversion:*
Pattern covers a specific version of a license.

Third part is the key of the corresponding non-version-specific pattern.
type:trait
Pattern covers a single trait occuring in licenses.
type:unversioned
Pattern covers a license without versioning scheme.
type:versioned:decimal
Pattern covers a license using decimal number versioning scheme.

EXAMPLES¶

Browse patterns¶

The "official" way to browse patterns is using App::RegexpPatternUtils:

    show-regexp-pattern-module --page-result -- License

Unfortunately, App::RegexpPatternUtils has a deep dependency tree. An alternative is to use Data::Printer and "less":

    perl -CS -MRegexp::Pattern::License -MDDP -e 'p %Regexp::Pattern::License::RE, fulldump => 1, output => stdout' | less -RS
