COMPLETING argument menu shown even when only one completion on paths that start ~/

[tesujimath]

What happened, and what did you expect to happen?

I typed a path prefix and hit TAB. There is only one completion, and it did complete on the command line, but it left the COPMPLETING argument menu up with a single entry.

Rather than simply continue typing the path, I had to hit ENTER to accept the menu. This seems non-ergonomic to me, as what else could I want, except the single matching path?

it23677> cd ~/vc/agr-d
<TAB>

it23677> cd /home/guestsi/vc/agr-devops/
 COMPLETING argument
/home/guestsi/vc/agr-devops/

I expected not to have a menu to dismiss.

I note that if I backspace-delete some characters and hit TAB again, so long as there is only a single completion possible, it does what I expected it to do in the first place, and completes without showing the single-entry menu.

Once I start a new command line, the completion engine goes back to the behaviour of always showing the menu.

This is a duplicate of #474.

[tesujimath]

I think it is not in fact a duplicate of that issue, although a comment on that issue observes the same behaviour.

But different issues I think. Perhaps that comment specifically about the menu belongs in this issue. 😁

Hmm, I guess I was a bit hasty there. Not enough caffeine yet.

However, if the not-quite-duplicate is fixed, then the current issue is moot.

A related issue that I think has been discussed in the forum but perhaps not on github, is that you also get a completion menu when the completion is unique, but does not match the case of what you typed. As in search for foo, and get Foo as the unique completion. But I think that makes a bit more sense, at least on case sensitive filesystem.

I think the right fix for the other issue is to produce completion(s) without expanding tilde, right? If that avoids the menu in this case, then yes, great solution.

Thanks for your insight here. 😊
