`SplitPane`¶

Since: Version 20220624-141144-bd1b7c5d

The functionality described in this section requires version 20220624-141144-bd1b7c5d of wezterm, or a more recent version.

Splits the active pane in a particular direction, spawning a new command into the newly created pane.

This assignment has a number of fields that control the overall action:

direction - can be one of "Up", "Down", "Left", "Right". Specifies where the new pane will end up. This field is required.
size - controls the size of the new pane. Can be {Cells=10} to specify eg: 10 cells or {Percent=50} to specify 50% of the available space. If omitted, {Percent=50} is the default
command - the SpawnCommand that specifies what program to launch into the new pane. If omitted, the default_prog is used
top_level - if set to true, rather than splitting the active pane, the split will be made at the root of the tab and effectively split the entire tab across the full extent possible. The default is false.

config.keys = {
  -- This will create a new split and run the `top` program inside it
  {
    key = '%',
    mods = 'CTRL|SHIFT|ALT',
    action = wezterm.action.SplitPane {
      direction = 'Left',
      command = { args = { 'top' } },
      size = { Percent = 50 },
    },
  },
}
