'%' not working

[davidmaxwaterman]

I have ~recently switched to Mac from Linux and was looking for a config that 'just works' and so I picked this setup.

After having used it for some time, I'm finding that the '%' key doesn't work...it's supposed to do 'matchpairs' - ie if it is on a '[' it should jump to the matching ']'.

If I 'set matchpairs' is shows matchpairs=(:),{:},[:] which looks correct.

Am I missing something special in maximum-awesome that means '%' isn't the same as regular vi?

Hey @davidmaxwaterman, I never new about the % key for jumping matchpairs, but I just tried it on the Rakefile and it seems to work fine for me.

match-pairs.mov

Here are the versions I tried it on.

maximum-awesome on  master
❯ vi -version
VIM - Vi IMproved 9.0 (2022 Jun 28, compiled Sep 30 2022 03:10:57)
Garbage after option argument: "-version"
More info with: "vim -h"

maximum-awesome on  master
❯ vim -version
VIM - Vi IMproved 8.2 (2019 Dec 12, compiled Mar  8 2021 07:21:32)

Ah, so it is supposed to work...that's good to know at least. You video, I think, shows it working, as you say. I normally use % to jump between the beginning/end of blocks in code, so I had to try it on function params too...and it doesn't work.

So, I'm wondering how to debug this further.

One thing I noticed with your video is that it appear to be the terminal version rather than the GUI version....and, indeed, if I just invoke using vim on the cli, % does actually work....so it is just the gui version....hrm, in the gui version, in my code, it doesn't work....but if I open a new tab, and try there, it does work.
So, it's not even just a difference between the cli/gui, but something to do with the actual files I'm editing....
Yes, so if I :n tmp.js, then insert:

(
)
{
}

and try to jump between those two...it doesn't work. [EDIT - I should add that this test also applies in the terminal, so totally nothing to do with vim/mvim]

So, something to do with javascript files?

What to try next?

[EDIT] I added a video of my own, showing it working in tmp.txt but not tmp.js

I had a suggestion from:
https://www.reddit.com/r/vim/comments/y7x4to/comment/iv1xd97/?context=3
that suggested it was a mapping, and :set map does seem to show some suspects that might be the culprit:

o  %           * v:<C-U>call <SNR>80_Match_wrapper('',1,'o') <CR>
v  %           * :<C-U>call <SNR>80_Match_wrapper('',1,'v') <CR>m'gv``
n  %           * :<C-U>call <SNR>80_Match_wrapper('',1,'n') <CR>

Another observation that came out of that experiment is that the '%' key does actually work the very first time...but not subsequent times.

I wonder if there's any way I can further investigate this issue to move towards a fix. Suggestions welcome.

Any more thoughts on this? I find that ']}' and '[{' are good enough, but I do miss '%'.

[SalvatoreT]

Unfortunately, I don't know what's causing it, nor can I reproduce it. ☹️

[davidmaxwaterman]

Oh, I didn't realise that. You mean % works for you even on a js file?

[SalvatoreT]

Ah, sorry I missed that. 🤦🏼
Yep, I reproduced it on a JavaScript file. 👍🏼

I'm wondering if there's something wrong with JSHint. I went to open React's dangerfile.js as an example, and I got this error.

Look like commenting out wookiehangover/jshint.vim fixes that.

diff --git a/vimrc.bundles b/vimrc.bundles

With that I can now use % exactly once as you described!

[davidmaxwaterman]

Oddly enough, in my ~/.vimrc.bundles file, that line is already commented out....as is the syntastic line.

I was curious how you managed to get that error output. I tried running vim -D tmp.js and it complains about line 6 in /opt/homebrew/Cellar/macvim/9.0.472_1/MacVim.app/Contents/Resources/vim/vimrc, which is set nocompatible.

Any thoughts?

Any more thoughts on this?

[SalvatoreT]

Unfortunately, I don't. I tried debugging this earlier and ran out of patience with it. Because it seems minor (to me), I haven't been able to push myself to work on this in my free time. I know this isn't the answer you're hoping for, but I wanted to give you an update.

[davidmaxwaterman]

LOL, indeed, fair enough.
