Identify library never returns "or later" for license

[garthwilliamson]

Ideally the reformat would leave -or-later on the end if it is "correct" otherwise. An alternative might be to add a new option to disable the license checks.

the license field is meant to be a SPDX identifier, "-or-later" is not a valid identifier

[garthwilliamson]

According to https://spdx.org/licenses/, there are many identifiers with the suffix, for example GPL-2.0-or-later. Because the LICENSE file is the same whether it's straight GPL or GPL-2.0-or-later, identify can't tell the difference.

ah right GPL cancer

surely if the licenses are byte identical then then or-later is redundant right?

[garthwilliamson]

I don't know - pypi doesn't seem to have very strict rules about getting these things exactly right, so it might not make any material difference.

If it bothers us enough, which pull request would you prefer? Option to avoid licence changes altogether, or to keep or-later when it already exists and GPL is in the string?

[asottile]

does your license contain an "or later" clause in its contents? if not -or-later is probably not correct. (though identify doesn't detect the or later clause as it is).

setup-cfg-fmt intentionally doesn't have options so definitely not that.

I suspect the actual fix is having identify identify the or later clause
