Additional context

What about cases of multiple argument that are mistyped or providing multiple arguments and just one is mistyped? How would that work?

[anshumanv]

To what extent are we checking that a flag is a mistype and matches some arg/flag? How is the diff of closest matching flag evaluated?

[rishabh3112]

I feel that a warning for wrong arguments is enough.

We're just taking the very first argument into account.

This is essentially an addition on top of what we already have onboard. Getting suggestions is definitely gonna add to the UX.

Saw the repo. 👍

I think showing help with warning in case any invalid flag is supplied is sufficient feedback. #1051

[ematipico]

How would that work with alias? -d or -c

[jamesgeorge007]

As of now it just checks for the fully qualified flag names ignoring aliases. #1211

Which is not ideal. If user passes a series of parameters and the last one is wrong, the feature would fail. It should check all the arguments

[jamesgeorge007]

In-fact the very first unknown argument.
