Error executing vim.schedule callback

[elianiva]

Hi there! I have this issue which came up pretty inconsistently. Here's the error message.

Error executing vim.schedule lua callback: ...pack/packer/opt/nvim-compe/lua/compe/utils/character.lua:31: attempt to perform arithmetic on local 'byte1' (a nil value)

I think it happens when there's not enough screen to display the documentation from a completion item.
Here's how to reproduce it.

• use this minimal init.vim
• open this file on the left and a split on the right. I suppose you could use whatever file but I couldn't reproduce it unless I use this file (out of several ones that I have)
• try to add + Math. on line 7, this is where the error happens
• if it didn't happen, remove the . and add it back

Screenshot using minimal init.vim:

Thanks in advance!

update: this is easily reproducible in c when you type #include <std.|>. | is the cursor and that's where the error happens.

Character.match = function(byte1, byte2)
-  local diff = byte1 - byte2
+  local diff = (byte1 or 0) - byte2
  return diff == 0 or diff == 32 or diff == -32
end

Doing this solves the issue but I don't know if this is a good permanent solution

Sorry for the lately reply.

I can't reproduce clangd/typescript-language-server both.

It is bit difficult (may be it is a potential bug of the matcher.lua because it is a complex codes)

[elianiva]

no worries. I can wait however long it would take until there's a solution for this :)
I've found my workaround so this isn't that big of an issue.

Sorry for annoying.

If you can reproduce easily, please detect the error place by debug branch.

#71

Ok, I've tried that and here's the debug info. https://paste.sh/zcGWAXps#HKoNPs_FWtgJpF2pGnvEG__E

Thank you! I will debug it.

Hm... I want to detect the input and the word that cause this error.

Matcher.score(
  Matcher.bytes2string({ 105, 110, 99, 108, 117, 100, 101 }),
  Matcher.bytes2string({ 105, 110, 99, 108, 117, 100, 101 })
)

It works fine (no errors).

Could you try to detect the word/input?

[elianiva]

The word is #include <. The error happens as soon as I press <
The full file is this.

#include <

int main(void)
{
  printf("Hello world");
}

[hrsh7th]

OK. I will push debug code for the above concern.

[hrsh7th]

Realy thank you for your help.

I've pushed to debug code.
If you have a time, please provide last debug information.
