Returns a map representing the differences found when attempting to match text against the SPDX matching template for license-or-exception-id. Returns nil if text or license-or-exception-id are nil, when license-or-exception-id is invalid (does not refer to a listed SPDX license or license exception), or when no differences were found (note that this last part is unlike the underlying Java library, which returns a non-nil ‘no differences found’ object in this case).

Returns the set of ids for all exceptions found in text (optionally limited to just the provided set of exception-ids), or nil if none were found.

Note: this function has a substantial performance cost. Callers are encouraged to break their ids into batches and call the 2-arg version with each batch in parallel (e.g. using clojure.core/pmap), then merge the results.

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 function may have a substantial performance cost.

Returns the set of ids for all licenses found in text (optionally limited to just the provided set of license-ids), or nil if none were found.

Note: this function has a substantial performance cost. Callers are encouraged to break their ids into batches and call the 2-arg version with each batch in parallel (e.g. using clojure.core/pmap), then merge the results.

Does the text contain the exception identified by exception-id somewhere within it?

Does the text contain the license identified by license-id somewhere within it?

Does the entire text match the exception identified by exception-id?

Does the entire text match the license identified by license-id?

Does text1 and text2 represent an equivalent exception?

Does text1 and text2 represent an equivalent license?
