AdjustPaneSize

Since: 20201031-154415-9614e117

AdjustPaneSize manipulates the size of the active pane, allowing the size to be adjusted by an integer amount in a specific direction.

If the pane is on the right hand side of a split and you adjust the size left by 1 then the split grows larger by 1 cell by expanding its size to the left. The pane to its left is reduced in size by 1 cell to accommodate the growth. If you were to adjust this same right hand side right by 1 cell, then the pane will shrink by 1 cell and move the split 1 cell to the right.

Here's a sample configuration that uses CTRL-A H to increase the size of the active pane by 5 cells in the left direction. The other vi style motion keys are used to adjust the size in their conventional directions, respectively.

local wezterm = require 'wezterm'
local act = wezterm.action

return {
  leader = { key = 'a', mods = 'CTRL' },
  keys = {
    {
      key = 'H',
      mods = 'LEADER',
      action = act.AdjustPaneSize { 'Left', 5 },
    },
    {
      key = 'J',
      mods = 'LEADER',
      action = act.AdjustPaneSize { 'Down', 5 },
    },
    { key = 'K', mods = 'LEADER', action = act.AdjustPaneSize { 'Up', 5 } },
    {
      key = 'L',
      mods = 'LEADER',
      action = act.AdjustPaneSize { 'Right', 5 },
    },
  },
}
