Re: [Patch] ruby-byebug@9.0.5

[Matthew Jordan <matthewjordandevops@yandex.com>]

Good Day Ben Woodcroft,

This is what I have so far, although I'm not that familiar with byebug
though. I'll try to dig a bit deeper to get a better understanding of
what's going on.

Wouldn't it be more useful to have one or versions of a package, since
guix is capable of handling multiple versions? Though I have no problems
upgrading the previous version, hopefully nothing will break.

Here a summary of test info. The test
"Byebug::SaveTest#test_save_shows_a_success_message" seems to fail cause
it's looking for a file in a home directory that doesn't exist. Setting
the HOME variable seems to solve that.

As for the other failing tests, they seem to expect to finish in the
temporary guix build directory.
