jump to wrong line in ruby

[leateng]

class A
  def abc
    a = []

    # a.each do |x|     #  line 5
    a.each do |x| 
    end
  end # line 8, cursor here
end

when curosr on line 8, press %, jump to line 5

can't reproduce. make sure your are in ruby-mode or enh-ruby-mode.

Or else, add below line into your "~/.emacs",

  (evilmi-load-plugin-rules '(ruby-mode enh-ruby-mode your-rub-mode) '(simple ruby))

[leateng]

Thank you for your reply.
I found the problem. When I enable tree-sitter-hl-mode, evil-matchit does not work properly in some cases.
Is this a bug of Emacs tree-sitter or evil-machit ?
Or my configuration?

I use doom Emacs
just add a few lines config

;; enable tree sitter highlight
(global-tree-sitter-mode)
(add-hook 'tree-sitter-after-on-hook #'tree-sitter-hl-mode)

;; enable evil-matchit
(global-evil-matchit-mode 1)

Only simple regex is used in ruby related code. Code should not be impacted by other plugins.

What's the major-mode in ruby file? Does M-x evilmi-jump-items work? Press C-h k %, what's output?

[leateng]

1. major mode is ruby-mode
2. M-x evilmi-jump-items works same as press % key
3. c-h k % output
   

[redguardtoo]

I can't reproduce the issue. What's M-x evilmi-version, maybe you can try 2.4.4?

[J0HN50N133]

I have the similar problem with you. I couldn't jump appropriately in OCaml. And our configuration is exactly the same.

(global-tree-sitter-mode)
(add-hook 'tree-sitter-after-on-hook #'tree-sitter-hl-mode)
(global-evil-matchit-mode 1)

[redguardtoo]

@JohnsonLee-debug , could you give me more details? A sample ocaml file could help a lot

Can't reproduce the issue. I've tried to toggle global-tree-sitter-mode or global-evil-matchit-mode several times.

ocaml algorithm was not written by me. But looks code is straight forward,
evilmi-ocaml-goto-word-beginning to get the beginning of the first keyword after the cursor, then jump.

[J0HN50N133]

Maybe it is caused by something in doom emacs. I use doom like @leateng did.

[redguardtoo]

Please note I use tree-sitter-0.18.0 stable version. Emacs API scan-sexps is used to jump between {}, [], ().

If the api fails, it might be the bug of unstable tree-sitter or major mode.

[redguardtoo]

Try the new hook evilmi-jump-hook,

See https://github.com/redguardtoo/evil-matchit#toggle-other-modes-beforeafter-jumping-to-the-matched-tag

2715515 add evilmi-jump-hook (Chen Bin)

[jlholm]

+1 – I'm having the same issue as @leateng & @JohnsonLee-debug. Similarly, I am using Doom Emacs.

@redguardtoo I've tried the new evilmi-jump-hook as suggested but it did not resolve the issue.

[redguardtoo]

Could you give me more details and some minimum example? evilmi version? Have you tested evil-matchit in vanllia emacs? Which package causes the issue? doom emacs version? I will download doomemacs and test.
