Please demonstrate this feature when there is a user-provided directory filter and a map is used.

And/or PathCompleter::file is being used with map

The intention of the split commits was for this test to overwrite the suggest_value_path_without_mapper, showing the change in behavior. Only the call to map and output should change in this commit.

All test additions should be done in the first commit

So @epage, i should do that same as i did for suggest_value_path_with_mapper (in the first commit showing the behaviour without mapper and then showing the behaviour with mapper right ?)

If you ran clippy on this, it would complain about the use of map_or. CI isn't catching it because we aren't running it on unstable features from non-default packages.

- These two are filtering under different conditions
- Logically, it feels odd that we're mapping on something that was filtered out. We shouldn't have to re-
filterinside themap.

hmm... so i am thinking of filtering first if its a directory and then the mapping if it contains c_dir
thats seem correct right?

map should only applied to content that matched filter.

Why this this being done? display order should be taken care of

the display_order in the else branch ensures that c_dir comes first, if i dont include display_order() in the else branch it does not sort it properly

If we filtered out d_dir, then it should be last. If it isn't, something else is going on and should be investigated and fixed.

A
mapAPI toPathCompleterand added its test, themapmethod allows customization of completion candidates after filtering, enabling use cases like highlighting directories, labeling etc
