This config option allows styling the elements that appear in the tab bar. This configuration supplements the tab bar color options.

Styling in this context refers to how the edges of the tabs and the new tab button are rendered. The default is simply a space character but you can use any sequence of formatted text produced by the wezterm.format function.

The defaults for each of these styles is simply a space. For each element, the foreground and background colors are set as per the tab bar colors you've configured.

The available elements are:

• active_tab_left, active_tab_right - the left and right sides of the active tab
• inactive_tab_left, inactive_tab_right - the left and right sides of inactive tabs
• inactive_tab_hover_left, inactive_tab_hover_right - the left and right sides of inactive tabs in the hover state
• new_tab_left, new_tab_right - the left and right sides of the new tab + button
• new_tab_hover_left, new_tab_hover_right - the left and right sides of the new tab + button in the hover state.

This example changes the tab edges to the PowerLine arrow symbols:

local wezterm = require 'wezterm';

-- The filled in variant of the < symbol
local SOLID_LEFT_ARROW = utf8.char(0xe0b2)

-- The filled in variant of the > symbol
local SOLID_RIGHT_ARROW = utf8.char(0xe0b0)

return {
  tab_bar_style = {
    active_tab_left = wezterm.format({
      {Background={Color="#0b0022"}},
      {Foreground={Color="#2b2042"}},
      {Text=SOLID_LEFT_ARROW},
    }),
    active_tab_right = wezterm.format({
      {Background={Color="#0b0022"}},
      {Foreground={Color="#2b2042"}},
      {Text=SOLID_RIGHT_ARROW},
    }),
    inactive_tab_left = wezterm.format({
      {Background={Color="#0b0022"}},
      {Foreground={Color="#1b1032"}},
      {Text=SOLID_LEFT_ARROW},
    }),
    inactive_tab_right = wezterm.format({
      {Background={Color="#0b0022"}},
      {Foreground={Color="#1b1032"}},
      {Text=SOLID_RIGHT_ARROW},
    }),
  }
}
