Custom regexp parameter for release version parsing

[dbelyaev]

Is it possible to add input parameter release_version_regexp so the user can supply its own expression to be used for release version parsing when available releases are fetched from GitHub?

As of now I see that action expects version in release to be in a short and usable form, but not all the repos are following this clear naming scheme.

It can be useful when trying to use depup with repos that are using some custom release names, for example:

• PMD with their PMD 6.35.0 (29-May-2021)
• checkstyle and their checkstyle-8.43
