SpdxLicence

An SPDX licence expression, each identifier as the SPDX licence list spells it: MIT OR Apache-2.0.

Software; not ordered; since Jadpo 0.1.0.

Make one

Build one from its text, SpdxLicence("MIT"), which checks it: text that isn't one breaks format.

text.parse(raw, as: SpdxLicence) reads one from its text; text that isn't one at all fails malformed, such as mit, Apache-2 or MIT or Apache-2.0.

Text, JSON and storage

text.from writes its canonical text, the one form text.parse reads back. JSON sends its canonical text as a string.

It is stored in one column named for the field, of type text. (MIT OR Apache-2.0) AND BSD-3-Clause is stored as '(MIT OR Apache-2.0) AND BSD-3-Clause'.

Shown to people

text.format(value, locale:) shows it to people in their locale.

With locale: Locale.en_gb:

Operations

It has the contract's own operations: text.parse, text.from, text.format, json.read, json.write and ==. It isn't ordered, so < and sorting don't take it. Every standard type meets one contract says how they work.
