Subject: recipetool: support PEP639-variant of license key in pyproject.toml
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9d1a7bb5d8aa94b74cd66edcb88e323c926d299b;p=thirdparty%2Fopenembedded%2Fopenembedded-core-contrib.git

recipetool: support PEP639-variant of license key in pyproject.toml

Python modules using PEP639-variant of the license key[1] are currently
returning Unknown as LICENSE when using recipetool create on them
because we try to parse the key as a dict but it is now an SPDX license
expression.

This adds support for PEP639-variant of the license key, though it does
not handle the newly added license-files key[2] as I couldn't find a
dual-licensed recipe which uses that mechanism yet.
