db option not recognized in 1.38 #316

Open hedges333 opened 1 year ago

hedges333 commented 1 year ago

Trying to do cover -db /tmp/cover_db with v1.38.

Unknown option: db
Invalid command line options at /[omitted]/lib/perl5/x86_64-linux/Devel/Cover/Report/Html_minimal.pm line 714.

I tried adding it as HARNESS_PERL_SWITCHES=-MDevel::Cover=-db,/tmp/cover_db and that didn't help either.

Thanks.

In bin/cover I found it's undocumented that I can run it as cover /tmp/cover and it will shift the DB path from @ARGV.

Not sure how to open a PR since I can't push my branch but here is "the solution":

@hedges333: fwiw, to create a PR, you'd first use https://github.com/pjcj/Devel--Cover/fork to create a fork, and then push your branch to your fork, and finally create the PR to this repository.
