licenses (plural) key in gemspecs doesn't seem to be recognised?

[dgmstuart]

Most gems just specify a single license, but the gemspec format also supports specifying a list of licenses:

https://guides.rubygems.org/specification-reference/#licenses=

It seems that these aren't recognised by licensed?

In particular the Ruby standard library gem stringio specifies s.licenses = ["Ruby", "BSD-2-Clause"]

https://github.com/ruby/stringio/blob/master/stringio.gemspec

...but the cached license yml doesn't seem to use this, and instead only finds license information from the README:

---
name: stringio
version: 3.0.1
type: bundler
summary: Pseudo IO on String
homepage: https://github.com/ruby/stringio
license: other
licenses:
- sources: README.md
  text: The gem is available as open source under the terms of the [2-Clause BSD License](https://opensource.org/licenses/BSD-2-Clause).

👋 @dgmstuart licensed is a wrapper around licensee which performs the actual license detection. Gemspec logic is handled in licensees Gemspec file matcher.

If you'd like to request different behavior for pulling license information from gemspec files you'll need to open an issue in the licensee repo. Licensed does by default use package manager file information by setting licensee's configuration option, so any change in licensee should be picked up the next time licensed updates dependency versions.

I'm going to close this because I'm not aware of anything for licensed to change for this feature request. Please feel free to reopen if you disagree.

Ah ok, I didn't realise that was a separate project - thank you for explaining 🙏

For reference: it seems that the licensee project has decided not to handle multiple licenses at the moment: licensee/licensee#246
