"Did you mean" hint on wrong command or flag

[saschagrunert]

We could tell the user what the closest command or argument match is by calculating the levenshtein distance between them.

What to do you think?

Should be optional tho

Good idea for a new feature. I always loved how git suggests this to us in case of a typo. I also agree that this needs to be optional where a user can enable this probably by a boolean flag if they feel they need it for their CLI.

I'd love this!!!

Related to the conversation in #826, I'd like to propose we only consider this feature for v2 🙏

Sounds good, I suggest to use a third party library to provide the necessary algorithms around it.

I'm in strong agreement here!

I found three main packages which all seem a bit unmaintained:

• https://github.com/toldjuuso/go-jaro-winkler-distance
• https://github.com/xrash/smetrics
• https://github.com/antzucaro/matchr

From an implementation perspective I tend to use the Jaro-Winkler distance to match the closet command/flag.

To start with a clean state I added go module support to matchr: antzucaro/matchr#10
