Using with vim

The motivation for calling hai from vim is to rewrite highlighted text using the same hai machinery you're accustomed to.

The feature leverages hai bye to call hai from the command-line with standard input (the highlighted text) substituting for the - argument.

Define custom key mapping

Add the following to your ~/.vimrc:

vnoremap <leader>h :!hai bye -

Usage:

  1. Highlight text in visual mode (v or V)
  2. Type \h (\ is the default leader)
  3. Complete the command with a quoted instruction, e.g., 'make concise'
  4. Press Enter

The full vim command line will look like: :'<,'>!hai bye - 'make concise'

Note: When you press : in visual mode, vim automatically inserts :'<,'> to indicate the selected range.

Define custom user command

Define H as a command to invoke hai bye by adding the following to your ~/.vimrc:

command! -range -nargs=* H <line1>,<line2>!hai bye - <args>

Usage: 1. Highlight text in visual mode (v or V) 2. Type :H 'clean up' 3. Press Enter

The full vim command line will look like: :'<,'>H 'clean up'

Extending functionality

Since hai bye accepts multiple commands, you can add /prep commands for default instructions:

vnoremap <leader>h :!hai bye - '/prep use simple language'

You may also want to use the -m and -u flags for better consistency.
