Caching multiple dependency environments

[ahlswedes]

Description:
I would like to be able to have separate dependency caches, one for my dev dependencies, and one for my production dependencies.

Justification:
I think it could be beneficial to have a separation of dependency environment installations. For example, if my dev dependencies only install packages for linting the code like black or flake8, but my production dependencies require all of my packages for running the program. If I want to add a new linting package to my dev dependencies, it shouldn't affect my cached prod dependencies.

Hello @ahlswedes. Thank you for your report. We'll investigate the feature request.

Hello @ahlswedes. If you use separate files for defining prod and dev dependencies I would suggest to use cache-dependency-path to specify paths for different files to generate separate cache for them. Otherwise, I would recommend to use actions/cache. According to the ADR cache logic should cover the most use cases.

For now I'm going to close the issue.
