<C-space> not toggling box on line

[thecarlhall]

I've tried using <C-space> to toggle a checkbox but it doesn't do anything for me. Checking :map shows n <C-Space> *@:TadaBox<CR> as the only mapping for ctrl-space. When I run :TadaBox it works fine. When I add, nmap <silent> <leader>r :TadaBox<CR> to .vimrc, this works fine. Any suggestions of what else I should test? Love the plugin!

Hey @thecarlhall glad to hear you like it!

That's no good if it's not working. Can you give me a minimally failing snippet I can debug with?

<C-Space> has a lot of gotchas on Windows terminal. Seems rather complex to me as also openssh may be involved.

Some context: microsoft/terminal#2865

I've also remapped to something else and it works fine.

For context, I'm on Mac using Alacritty w/ tmux and tested with Terminal w/o tmux.

Minimal failing snippet:

- Inbox:
  - A test task

There's a lot of folks on the internet calling out this keybinding in many places. One fix I've just found from vimwiki was to add this to .vimrc:
nmap <silent> <C-@> :TadaBox<CR>

Hmm, @thecarlhall I use Alacritty on Mac w/tmux coincidentally too, I tried on every single character in that string and it worked fine.

Any suggestions on what to try?

[thecarlhall]

Ha! I haven't yet found anything else trapping this key sequence. Adding the nmap above fixed this on 2 machines (macOS 11 & 12). <C-V> <C-space> shows ^@, so I think the sequence is making through to vim.

I cleaned out my .vimrc to the below text for testing, but still couldn't get C-space to call TadaBox until adding the nmap line from above. The mystery continues...

set nocompatible
filetype plugin indent on

call plug#begin('~/.vim/bundle')
Plug 'dewyze/vim-tada'
call plug#end()

Extra data point: I see the issue in Alacritty, Terminal, and now Kitty. I'm starting to wonder if this is deeper than the terminal emulator, or in a custom setting I can't/haven't found.

Alright, so the issue is I am using Neovim, but you are talking about vim. I found that vim doesn't have the <C-Space> but it is the same as <C-@>. Link. Try setting:

let g:tada_map_box = '<C-@>`

[dewyze]

If that works for you, I'll see if I can add to the config to detect vim or neovim and set it accordingly.

[thecarlhall]

Nailed it! You're also correct in that I'm using Vim (8.2) rather than NeoVim. Thanks for helping me nail this down.

[dewyze]

@thecarlhall I think this should fix it, let me know: bcf07ac

[thecarlhall]

Works great! I removed let g:tada_map_box = '<C-@>' from .vimrc, and fetched & rebased your main branch. All is well now 😄
