SplitVertical

Since: 20201031-154415-9614e117

Splits the current pane in half vertically such that the current pane becomes the top half and the new bottom half spawns a new command.

local wezterm = require 'wezterm'

return {
  keys = {
    -- This will create a new split and run your default program inside it
    {
      key = '"',
      mods = 'CTRL|SHIFT|ALT',
      action = wezterm.action.SplitVertical { domain = 'CurrentPaneDomain' },
    },
  },
}

SplitVertical requires a SpawnCommand parameter to specify what should be spawned into the new split.

local wezterm = require 'wezterm'

return {
  keys = {
    -- This will create a new split and run the `top` program inside it
    {
      key = '"',
      mods = 'CTRL|SHIFT|ALT',
      action = wezterm.action.SplitVertical {
        args = { 'top' },
      },
    },
  },
}
