Ctrl-C in visual mode terminates some lua execution

[boltlessengineer]

Neovim version (nvim -v | head -n1)

NVIM v0.10.0-dev-2062+ga7550a20e

Operating system/version

Ubuntu 22.04

How to reproduce the issue

When I type CTRL-C on Visual mode, I sometimes see error message below. It doesn’t happen always and I can’t reproduce immediately with same visual selection, so it’s really hard to reproduce. But it happens often enough to notice as a bug. (I’m not sure it’s issue of nvim-ufo side or neovim itself)

I usually use CTRL-C to quit Visual mode and I encountered this issue several times.

Expected behavior

Ctrl-C should not interrupt any internal nvim-ufo code.
Vim should go back to Normal mode instead of printing errors.

Actual behavior

Here are errors I’ve encountered when I press Ctrl-C in visual mode.

Error in decoration provider ufo.end:

I’ve seen other error messages but they all have Error executing lua: Keyboard interrupt in common.

Edit: add more error message

xnoremap <C-c> <Esc> remap should work.

[boltlessengineer]

You are genius. I'll try that for a while and see if problem disappears.

I think this behavior should be prevented by default though.

@boltlessengineer @kevinhwang91 for what it's worth, I already have c-c mapped too esc in insert mode and this happens randomly to me too. At the same time it also will make my entire gutter column filled with random vimscript jargon of like v:lua.StatusCol() or something. I'd take a screenshot of it but it bothered me so much that it happened constantly that I removed nvim-ufo from my configuration

I removed the xnoremap <C-c> <esc> after this issue get closed, but I’m facing similar issue on <C-c> keypress on visual mode.

if not ok and (type(msg) ~= 'string' or not msg:match('Keyboard interrupt\n')) then

debug yourself.
