Editing AI Completion In The Shell

LLMs are fantastic for programming. I use ChatGPT, Claude, and Copilot routinely. One place where I didn't have a good workflow was my terminal, but [https://x.com/arjie/status/1575201117595926530 I found a way that I find quite pleasant and I've been using it for a few months].

== Steps ==

1. Install <code>neovim</code>

2. Install Copilot on it using [https://github.com/github/copilot.vim copilot.vim]

3. Set <code>EDITOR=nvim</code>

4. Use Ctrl-X Ctrl-E at your command-prompt to enter your Neovim-enabled Copilot

== Additional Tips ==

Here's my <code>~/.config/nvim/init.vim</code> for the relevant bits. I use <code>vim-plug</code> which I've found quite useful to manage vim plugins.

<syntaxhighlight lang=vim>
call plug#begin()
  Plug 'Shougo/deoplete.nvim', { 'do': ':UpdateRemotePlugins' }
  Plug 'github/copilot.vim'
call plug#end()

" Deoplete
let g:deoplete#enable_at_startup = 1
"" <TAB>: completion.
inoremap <expr><TAB>  pumvisible() ? "\<C-n>" : "\<TAB>"
inoremap <expr><S-TAB>  pumvisible() ? "\<C-p>" : "\<TAB>"
</syntaxhighlight>

I also use <code>zsh</code> with <code>oh-my-zsh</code> and [https://starship.rs/ starship.rs] so entering and leaving this is quite easy and pleasant. I can type some at the command-prompt and then go back to <code>nvim</code> and so on because it will expand things like <code>!!</code> and so on.
