@jthegedus apologies for the direct ping, any chance of getting a review, here, please?

Some test cases will likely need to be updated.

The Fish issue is unrelated and one I need to resolve.

[StingRayZA]

Thanks @jthegedus
Let me see if I can get the failing test(s) updated :)

[StingRayZA]

@jthegedus Tests updated (I've rebased my branch on the upstream master - so commit history is clean)

I wasn't able to figure out how to do a multiline match, so I've matched on partial strings. I did add a specific test to separately check for these particular outputs.

nudging this gently :)

Sorry for the late response here. Thanks for the PR @StingRayZA ! Unfortunately, asdf has been rewritten in Go (https://github.com/asdf-vm/asdf/releases/tag/v0.16.0) so this PR cannot be applied. I'm going to close it now.

Please continue discussion under #1753. I think this feature would be a welcome improvement in 0.16.0. I think we'll want to add some sort of verbose flag or verbose output mode to enable this extra output from asdf, as many users (myself included) typically do not want to see more information during installation. Thanks!
