spdx.regexes — com.github.pmonks/clj-spdx 1.0.214

Regex related functionality. This functionality is bespoke (it does not use any logic from Spdx-Java-Library).

addition-ref-re clj

(addition-ref-re)

Returns a regex (Pattern) that can find or match any SPDX AdditionRef. The regex provides these named capturing groups:

• AdditionDocumentRef (optional) - captures the DocumentRef tag of an AdditionRef, if it contains one
• AdditionRef (always present) - captures the AdditionRef tag of an AdditionRef

Notes:

• caches the generated Pattern object and returns it on subsequent calls, so is efficient when called many times

build-re clj

(build-re ids)

(build-re ids
          {:keys [case-sensitive? include-license-refs? include-addition-refs?]
           :or {case-sensitive? false
                include-license-refs? false
                include-addition-refs? false}
           :as opts})

Returns a regex (Pattern) that can find or match the given SPDX ids (a sequence of Strings) in a source text. Returns nil if ids is nil or empty.

The regex provides these named capturing groups:

• Identifier (always present) - captures the entire identifier, LicenseRef or AdditionRef
• DocumentRef (optional) - captures the DocumentRef tag of a LicenseRef, if it contains one
• LicenseRef (optional) - captures the LicenseRef tag of a LicenseRef
• AdditionDocumentRef (optional) - captures the DocumentRef tag of an AdditionRef, if it contains one
• AdditionRef (optional) - captures the AdditionRef tag of an AdditionRef

Groups should not be accessed by index, as the groups in the returned regexes are not part of the public contract of this API, and are liable to change over time. You may choose to use something like rencg to ensure your code is future proof in this regard.

ids will appear in the regex sorted from longest to shortest, so that more specific values are preferentially found or matched first - this avoids mismatches when one id is a subset of another id (e.g. GPL-2.0 and GPL-2.0-or-later).

opts are:

• case-sensitive? (boolean, default false) - controls whether SPDX identifier matching is case sensitive or not. The spec explicitly states that SPDX identifiers are not case sensitive, but there may be cases where case sensitive matching is preferred. Note that regardless of this setting, LicenseRefs and AdditionRefs are always matched case sensitively - this is required by the spec.
• include-license-refs? (boolean, default false) - controls whether LicenseRef support is also included in the regex
• include-addition-refs? (boolean, default false) - controls whether AdditionRef support is also included in the regex

exception-ids-re clj

(exception-ids-re)

Returns a regex (Pattern) that can find or match any SPDX license exception identifier, or AdditionRef in a source text.

Specifics of the regex are as for build-re.

Notes:

• caches the generated Pattern object and returns it on subsequent calls, so is efficient when called many times

ids-re clj

(ids-re)

Returns a regex (Pattern) that can find or match any SPDX license identifier, SPDX exception identifier, LicenseRef, or AdditionRef in a source text.

Specifics of the regex are as for build-re.

Notes:

• caches the generated Pattern object and returns it on subsequent calls, so is efficient when called many times

init! clj

(init!)

Initialises this namespace upon first call (and does nothing on subsequent calls), returning nil. Consumers of this namespace are not required to call this fn, as initialisation will occur implicitly anyway; it is provided to allow explicit control of the cost of initialisation to callers who need it.

Note: this method may have a substantial performance cost.

license-ids-re clj

(license-ids-re)

Returns a regex (Pattern) that can find or match any SPDX license identifier, or LicenseRef in a source text.

Specifics of the regex are as for build-re.

Notes:

• caches the generated Pattern object and returns it on subsequent calls, so is efficient when called many times

license-ref-re clj

(license-ref-re)

Returns a regex (Pattern) that can find or match any SPDX LicenseRef. The regex provides these named capturing groups:

• DocumentRef (optional) - captures the DocumentRef tag of a LicenseRef, if it contains one
• LicenseRef (always present) - captures the LicenseRef tag of a LicenseRef

Notes:

• caches the generated Pattern object and returns it on subsequent calls, so is efficient when called many times
