I've slowly adding more and more lua functions into my neovim configuration, and recently I noticed a pattern for a class of functions that reach out to run shell commands that can be abstracted away.

Telegraph.nvim #

Check out the project readme for the most up to date details on the plugin itself.

Motivation #

I want a simple way to make remaps into shell commands that can open new tmux windows, popups, or just run a command with context from the editor.

For example I want to make remaps to do things like open the current file in lookatme.








        

# vim :terminal
nnoremap <leader>s <cmd>Telegraph pipx run lookatme {filepath} --live-reload --style gruvbox-dark<cmd>

# tmux session
nnoremap <leader><leader>s <cmd>lua require'telegraph'.telegraph({cmd='pipx run lookatme {filepath} --live-reload --style gruvbox-dark', how='tmux'})<CR>

# tmux popup
nnoremap <leader><leader>S <cmd>lua require'telegraph'.telegraph({cmd='pipx run lookatme {filepath} --live-reload --style gruvbox-dark', how='tmux_popup'})<CR>

The main goal here is that remaps become one liners that can just be put directly in my init.vim without creating a whole new lua module for each shell command I want to bind.

how #

telegraph takes in a how argument to determine where to tun the command.j

  • term(default) runs command in the built in terminal
  • tmux runs command in a new tmux session and joins it.
  • tmux_popup runs command in a tmux popup window.
  • tmux_popup_session runs command in a tmux session and displays it in a popup
  • subprocess runs command in a subprocess

Format strings #

The current set of format strings that can be used with telegraph. Placing these in braces {} within your command will get rendered into something with context from the editor.

  • cword - the current word under the cursor
  • cWORD - the current BIG Word under the cursor
  • cline - the current line under the cursor
  • filepath - the filepath of the current file
  • filename - the filename of the current file
  • parent - the parent directory of the current file
  • current_session_name - name of the current tmux session
  • cwd - the current working directory
