`<CTRL_C>` breaks lualine

[nvim-lualine]

`` breaks lualine

from lualine.nvim.

I solved by mapping <C-C> -> <C-[> as a workaround.

I stand by my point that it's not a lualine issue nor is it your configuration issue. All we are doing in our filetype components is calling vim.fn.expand functions. My guess is that it's a neovim/vim bug. Go ahead and submit an issue but I think you need to find a real cause of this crash as I suspect they would blame us if you refer a plugin with your ticket.

Mmm, this looks like it's not an issue with lualine but with the lua nvim api. Can you confirm that CTRL_C also breaks other lua plugins?

[0ihsan]

I haven't tried and don't know how to. Maybe secretly but this one was obvious.
Should I create the issue on https://github.com/neovim/neovim?

Can you provide more information of how to reproduce it ? It's proving to be really hard to reproduce . If we can find a easier way to reproduce it we can test it on other plugins ..

[0ihsan]

I don't know how to reproduce exactly but I collected some key points I realised this issue occurs.

1. ✅ No Problem

1. Open nvim
2. Press i or a
3. Press CTRL-C
4. Go to step 2

2. ✅ No Problem

1. Open nvim
2. Press i or a
3. Type "hello"
4. Press CTRL-C
5. Go to step 2

3. ❌ Issue Occurs

1. Open an empty python file nvim x.py
2. Press i or a
3. Press CTRL-C
4. Press i or a one more time (sometimes more than twice)
5. Press CTRL-C
6. See the status line disappeared and error message printed.

So, I suspect that this is something to do with filetypes or Python specific. I tried other filetypes and saw they are affected too. Here the filetypes I tried

• ❌ Python
• ❌ C
• ❌ C++
• ❌ Rust

I also tested how many times should I go to insert mode and normal mode again to reproduce this issue.
(I counted [i+CTRL-C] as 1)

• nvim x.cc: 5, 2, 3, 3, 4, 5, 2, 4, 7...

So, I couldn't see I pattern here.

Thanks for the info. In your config I can see you are using separate function for relative paths . But
lualines filename component provides relative path too . You can do

lauline_c = {{'filename', full_path = true}},

You can checkout Component options for details :)

Thank you, but I also have the filename blocking mechanism for terminal buffers in that function.

I suspect they would blame us if you refer a plugin with your ticket.

Not true . The neovim guys are pretry cool . I had mentioned this issue on neovim gitter . This issue needs better way of reproduceing if the cause is ever to be found . After aton of attempts I was only able to make it happen twice . Also it just happens randomly . Trying aton of times the same thing and wating for a bug to affect is npt realistic to do . Also I was actualy gona ask @ihsanturk are you using current master of neovim? I'm using current master and this issue almost naver happens . If you're using an old version can you try current master maybe this has been partialy solved already :)

[0ihsan]

I am using v0.5.0-dev. I will try master.
Thanks.

I'm using nightly builds and this happens about once every hour for me. I cannot find a way to reliably reproduce.
