Custom `C-i` bindings do not play well with `citar-open` and `RET`

[dschrempf]

Describe the bug In citar-open, pressing RET results in an error <C-i> is undefined.

To Reproduce

1. Set

  (define-key input-decode-map (kbd "C-i") [C-i])

2. Bind <C-i>, for example using general:

  (general-mmap "<C-i>" #'better-jumper-jump-forward)

3. Run citar-open and press RET.

Expected behavior The entry is opened.

Emacs version: 29.1

Context

• Most likely related to https://github.com/emacs-citar/citar/issues/707.
• Setting (setq citar--multiple-setup (cons "<tab>" "RET") is a workaround (but in my opinion it should not be necessary).
• Could be a problem of my setup (I try to distinguish between C-i and <tab>

Just in case, OS and (if relevant) distro and desktop?

When you get a chance, @aikrahguzar, any input?

[aikrahguzar]

This is exactly #707 and I don't know of any completely clean solution for that since it is a workaround for a limitation of completion ui. Changing the default value of citar--multiple-setup to use <tab> is the only option I can think of but I don't know if there are any unintended consequences.

@dschrempf - thoughts?

Doesn't seem like there's much we can do about this?

[dschrempf]

Using the workaround is an option for me, but I do not know if this situation is desired.

I do not know the internals of citar (Does it use keybinding macros?), but in opinion, rebinding a key should not lead to an error in a seemingly independent library. If there is no way to fix this, so be it :shrug:. Citar is a great package, thank you!, and I am happy that it works the way it does :smile:.

@aikrahguzar did mention changing the default value as a possibility.

This would mean that citar does not anymore work as expected when Emacs is used from the terminal, is that so?

Also: The completion UI that you mentioned. Is this an external library?

IDK; that would obviously be a problem if so.

I think he meant completing-read.
