Subject: 29.0.50; fido-mode and ssh not listing hosts
Date: Thu, 17 Feb 2022 15:47:57 +0100

Hi:

Recently I have found that icomplete does not offer host completions
after /ssh:

After some check I got this minimal snippet:

emacs -Q
M-x fido-mode
C-x C-f /ssh:<tab>

Somehow fido mode removes the latest colon (:) and tries to get
completion for /ssh so not host are shown (even in the completions
buffer).

If I choose at this point some of the options (sshx:, ssh:, sshfs:) it a
buffer `ssh:` is created at / (read only of course.)

trying a bit more like:

C-x C-f /ssh:m<tab> (I have many servers starting with m in my ssh config)

It does not show anything as completion but shows [No matches] while
normally in *Completions* appear all the hosts defined in .ssh/config.

I tried with icomplete and the problem seems to be only with fido.

This is a duplicate of bug#51386, see <https://debbugs.gnu.org/51386>.
I've merged both bugs.

 Completion)
Date: Wed, 15 Feb 2023 19:31:24 +0100

Hi again:

The initial problem seems to be solved because:

C-x C-f /ssh:<tab>

Opens the *Completions* buffer with right completions...

But

Somehow I am still getting a similar problem remaining. Why in fido
mode?:

C-x C-f /ssh:

does not offer a completion list with the hosts or user names or anything?

Actually:

C-x C-f /ssh:<RET>

In opens dired in the home of a random server from my config but I don't
know how it is selected. What I am missing here?

Best,
Ergus

Don't know.

I'm not sure it is Tramp related. When I call 'emacs -Q -f fido-mode'
and do

C-x C-f /s <RET>

it expands the minibuffer to '/afs/'. So it is fido which selects
(randomly?) one of the completion candidates. According to
icomplete-fido-ret, it isn't randomly, but
(car completion-all-sorted-completions) - and this is empty, because above.

That's why fido opens a selected server, instead of showing it in the
minibuffer.

I don't know whether we shall discuss it here in this bug report (and
friends). Perhaps it is worth a new bug report, because it is about
behavior of <RET>, and not od <TAB>. And we definitely need somebody who
knows fido internals.

Well, I've pushed a change to master which should improve the
situation. Could you, pls, check?

Hi Michael:

It works much better now! There is a detail when opening the connection
that a message appears in the same place than the prompt/cursor... but
that's not part of this issue I think... When I have a reproducible
snippet I will open another bug report.

Very very thanks!!!

Ergus

Does it help to decrease tramp-verbose to 2?
