Preselect first candidate on jinx-correct with vertico

[vspinu]

Hello!

I have switched from flyspell and while I am a vertico user I still don't find the UI efficient enough (for all the reasons already mentioned in #30).

The workarounds proposed in #30 are rather complex for my taste. So I would be reasonably happy to achieve a minimal vertico setup by reusing the triggering key for vertico-next and auto-selecting the first candidate from the list. This would come close to flyspell-autocorrect-previous-word for me.

I bind M-$ to vertico-next:

(define-key jinx-correct-map (kbd "M-$") #'vertico-next)

What is left is preselecting the first candidate in the menu but I cannot make this work. My vertico-preselect is set to #'first. I have also tried advising jinx--correct-setup to set vertico--index to 0, but that does not help.

Would you be so kind to advice for how to achieve the first candidate pre-selecton?

Thanks!

I am not sure what you want to achieve exactly, but you can press the key 1 to quickly select the first candidate and commit it directly. You could also try keyboard macros.

For example this keyboard macro M-$ corrects the nearest misspelling with the first suggestion:

(keymap-global-set "C-M-$" #'jinx-correct)
(keymap-global-set "M-$" "C-M-$ 1")

You could also bind M-$ to 1 in the jinx-correct-map:

(keymap-global-set "M-$" #'jinx-correct)
(keymap-set jinx-correct-map "M-$" "1")

Then you can press M-$ M-$ to correct the nearest misspelling.

Regarding vertico-preselect=first - this does not work since Jinx passes the uncorrected word as default to completing-read. Default return values take precedence in Vertico, such that they can be committed with RET.

I am not sure what you want to achieve exactly,

I am trying to get as close as possible to the behavior of flyspell-correct-word-before-point which I bind to C-; and can repeatedly invoke to substitute the mispelled word with available candidates. Thus to substitute with the first candidate I need to press C-; once, second twice etc. In 98% of cases it's the first candidate.

If I bind C-; to jinx-substitute and to vertico-next inside the jinx-correct-map I would need to press C-; twice and then RET. So it's 3 keys - way to slow. Thus, I want to pre-select the first occurrence and simply press RET.

I have tried a macro per your suggestion (keymap-global-set "C-;" "M-$ C-n") but it does not work for some peculiar reason.

My ideal scenario would be to be able

1. preselect first candidate in vertico buffer and invoke the action without closing the vertico buffer
2. on vetico-next move to next candidate and again invoke the action without closing the vertico completion

For the first candidate selection I have tried the following but it does not work. During the setup the completion buffer is still not available:

(defun my/vertico-setup-for-jinx ()
  (when (eq this-command 'jinx-correct)
    (vertico-first)))

(advice-add 'vertico--setup :after #'my/vertico-setup-for-jinx)

Did you try the function provided at #30 (comment)? How close is this to your desired behavior?

Implementing this via vertico-next and performing the action would work with embark-dwim I guess, but it would be a hack.

For the first candidate selection I have tried the following but it does not work. During the setup the completion buffer is still not available:

Delaying should help.

(defun my/vertico-setup-for-jinx ()
  (when (eq this-command 'jinx-correct)
    (run-at-time 0 nil (lambda () (vertico-next) (vertico--exhibit)))))

Sorry for the late reply. I have tried the solution in the thread. It's very fragile - breaks on multi-word substitutions. Also nice additionons like adding to the dictionary are lost. So I would very much like to preserve vertico completion but with the enhancements that I have listed above.

Delaying should help.

Thanks! It does help.

Any easy way to replace/preview the misspelled word with the selected candidate in the completion buffer? Something like consult preview option?

I actually started wondering now, would maybe a consult add-on would be more appropriate for this use case, instead of hacking jinx and vertico directly.

Well, Consult has consult--insertion-preview for this purpose, but we cannot use it here, and I want to avoid entangling the packages too much.
