local tym = require('tym')

tym.set_config({
  shell = '/bin/bash',
})

tym.set_timeout(coroutine.wrap(function()
  local i = 0
  local message = 'echo "hello World!"'
  while i < #message do
    i = i + 1
    tym.put(message:sub(i, i))
    coroutine.yield(true)

Prevent tmux's key inputs delay

Key inputs alt-h,j,k,l for switching tmux's pane is often delayed when tmux is busy. This is the fix for it.

local tym = require('tym')

local remap = function (a, b)
  tym.set_keymap(a, function()
    tym.send_key(b)
  end)
end
remap('<Alt>h', '<Alt>Left') -- remap as meta key inputs
remap('<Alt>l', '<Alt>Right')
remap('<Alt><Shift>h', '<Alt><Shift>Left')
remap('<Alt><Shift>l', '<Alt><Shift>Right')

Scroll mouse wheel to set window transparency/font scale

You can increase/decrease window transparency by pressing Ctrl + Shift + Down / Ctrl + Shift + Up or Shift + mouse wheel and increase/decrease font scale by Ctrl + mouse wheel.

local tym = require('tym')

function update_alpha(delta)
  r, g, b, a = tym.color_to_rgba(tym.get('color_background'))
  a = math.max(math.min(1.0, a + delta), 0.0)
  bg = tym.rgba_to_color(r, g, b, a)
  tym.set('color_background', bg)
  tym.notify(string.format('%s alpha to %f', (delta > 0 and 'Inc' or 'Dec'), a))
end

tym.set_keymaps({
  ['<Ctrl><Shift>Up'] = function()
    update_alpha(0.05)
  end,
  ['<Ctrl><Shift>Down'] = function()
    update_alpha(-0.05)
  end,
})

tym.set_hook('scroll', function(dx, dy, x, y)
  if tym.check_mod_state('<Ctrl>') then
    if dy > 0 then
      s = tym.get('scale') - 10
    else
      s = tym.get('scale') + 10
    end
    tym.set('scale', s)
    tym.notify('set scale: ' .. s .. '%')
    return true
  end
  if tym.check_mod_state('<Shift>') then
    update_alpha(dy < 0 and 0.05 or -0.05)
    return true
  end
end)
