Support For Hide-able NeoVim :terminal Buffers

Status: experimental

1. Start a new shell terminal :Term
2. Switch back to some other buffer, maybe closing the terminal window first, for example:
   • <C-\><C-n> to return to normal mode
   • <C-w>c to close the terminal window
   • NOTE this does not kill the running terminal, it continues in the background, and can be seen in the buffer list
3. Return to the running shell terminal with :Term
   • NOTE if there is a window already showing the terminal, than it is focused in insert mode instead of switching the current window

May use the :TermSplit or :TermVSplit commands to work in a split, instead of changing the current window. Similarly :TermHUD creates a fixed-height bottom window. Like :Term these commands focus any existing window if possible, rather than creating a new split window.

You may also specify a different shell to run as in:

• :Term zsh
• :Term powershell.exe
• :Term python NOTE any interactive terminal REPL should work

You may specify a different default shell in $MYVIMRC by setting g:termhide_default_shell:

let g:termhide_default_shell = 'powershell.exe'

Otherwise the default shell is used (see :help 'shell'). Be careful when changing this, as it may break other plugins that make assumptions about the default shell on Windows or Unix.

Easy HUD toggle:

nnoremap <leader>` :TermHUD<cr>
tnoremap <leader>` <C-\><C-n><C-w>c

Easily switch to a terminal:

nnoremap <leader>$ :Term<cr>

And easier exits from a terminal:

" Back to wherever we were before this terminal
tnoremap <C-\><C-o> <C-\><C-n><C-o>

" Close terminal window, e.g. when it was in a new split
tnoremap <C-\><C-c> <C-\><C-n><C-w>c

A :Ghud command is also provided to easily open fugitive's :Gstatus buffer in a fixed hud window at the bottom.

neovim-termhide follows the standard runtime path structure. Install with something like vim-plug:

Plug 'jcorbin/neovim-termhide'

• improve the HUD mode
• change default modality of the :Term command? or instead provide a a higher level <plug>(term) entry point
• floating window mode?
