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

VERSION
Version v3.1.92

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.

PATTERNS
Single licenses
Patterns each covering a single license.

Each of these patterns has exactly one of these tags: type:singleversion:*
type:unversioned type:versioned:decimal .

License combinations
Patterns each covering a combination of multiple licenses.

Each of these patterns has the tag type:combo .

License groups
Patterns each covering either of multiple licenses.

Each of these patterns has the tag type:group .

* bsd

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.

* 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.

Last part of tag 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.

DEPRECATED TAGS
Tags not documented in this POD, specifically non-hierarchical tags, are
deprecated and will be dropped in a future release.
