WezTerm Tabs

This project provides a configurable tab bar for WezTerm, a GPU-accelerated terminal emulator.

Installation

This project works with the native plugin system provided by WezTerm.

Modify your WezTerm configuration file (~/.config/wezterm/wezterm.lua) to include the status bar script:

    local wezterm = require 'wezterm'
    local config = wezterm.config_builder()

    ...

    wezterm.plugin
      .require('https://github.com/yriveiro/wezterm-tabs')
      .apply_to_config(config)

Setup

To customize the plugin, the method apply_to_config accepts a second argument for the plugin options.

In this example, we are configuring the position of the tab bar.

    local wezterm = require 'wezterm'
    local config = wezterm.config_builder()

    ...

    wezterm.plugin
      .require('https://github.com/yriveiro/wezterm-tabs')
      .apply_to_config(config, { tabs = { tab_bar_at_bottom = false } })

[!NOTE] This plugin uses Retro Bar appearance to work, that means you need to have configured the tab_bar color properties

config.colors = {
  tab_bar = {
    -- The color of the strip that goes along the top of the window
    -- (does not apply when fancy tab bar is in use)
    background = '#0b0022',

    -- The active tab is the one that has focus in the window
    active_tab = {
      -- The color of the background area for the tab
      bg_color = '#2b2042',
      -- The color of the text for the tab
      fg_color = '#c0c0c0',

      -- Specify whether you want "Half", "Normal" or "Bold" intensity for the
      -- label shown for this tab.
      -- The default is "Normal"
      intensity = 'Normal',

      -- Specify whether you want "None", "Single" or "Double" underline for
      -- label shown for this tab.
      -- The default is "None"
      underline = 'None',

      -- Specify whether you want the text to be italic (true) or not (false)
      -- for this tab.  The default is false.
      italic = false,

      -- Specify whether you want the text to be rendered with strikethrough (true)
      -- or not for this tab.  The default is false.
      strikethrough = false,
    },

    -- Inactive tabs are the tabs that do not have focus
    inactive_tab = {
      bg_color = '#1b1032',
      fg_color = '#808080',

      -- The same options that were listed under the `active_tab` section above
      -- can also be used for `inactive_tab`.
    },

    -- You can configure some alternate styling when the mouse pointer
    -- moves over inactive tabs
    inactive_tab_hover = {
      bg_color = '#3b3052',
      fg_color = '#909090',
      italic = true,

      -- The same options that were listed under the `active_tab` section above
      -- can also be used for `inactive_tab_hover`.
    },

    -- The new tab button that let you create new tabs
    new_tab = {
      bg_color = '#1b1032',
      fg_color = '#808080',

      -- The same options that were listed under the `active_tab` section above
      -- can also be used for `new_tab`.
    },

    -- You can configure some alternate styling when the mouse pointer
    -- moves over the new tab button
    new_tab_hover = {
      bg_color = '#3b3052',
      fg_color = '#909090',
      italic = true,

      -- The same options that were listed under the `active_tab` section above
      -- can also be used for `new_tab_hover`.
    },
  },
}

Available configurations

Tabs Section

Controls the basic behavior and appearance of tabs.

tabs = {
  -- Position the tab bar at the bottom of the window
  tab_bar_at_bottom = true,

  -- Controls visibility of the tab bar when only one tab exists
  hide_tab_bar_if_only_one_tab = false,

  -- Maximum width of each tab in cells
  tab_max_width = 32,

  -- Whether to restore zoom level when switching panes
  unzoom_on_switch_pane = true,
}

UI Section

Defines various UI elements including separators and program-specific icons.

Separators

Custom Unicode characters for tab separators:

ui.separators = {
  -- Powerline-style solid arrow pointing left
  arrow_solid_left = '\u{e0b0}',

  -- Powerline-style solid arrow pointing right
  arrow_solid_right = '\u{e0b2}',

  -- Powerline-style thin arrow pointing left
  arrow_thin_left = '\u{e0b1}',

  -- Powerline-style thin arrow pointing right
  arrow_thin_right = '\u{e0b3}',
}

Icons

Program-specific icons using Nerd Fonts:

ui.icons = {
  -- Development Tools
  ['debug'] = wezterm.nerdfonts.cod_debug_console,
  ['cargo'] = wezterm.nerdfonts.dev_rust,
  ['git'] = wezterm.nerdfonts.dev_git,
  ['go'] = wezterm.nerdfonts.seti_go,
  ['lua'] = wezterm.nerdfonts.seti_lua,
  ['node'] = wezterm.nerdfonts.md_hexagon,
  
  -- Shells and Terminals
  ['bash'] = wezterm.nerdfonts.cod_terminal_bash,
  ['zsh'] = wezterm.nerdfonts.dev_terminal,
  
  -- Text Editors
  ['nvim'] = wezterm.nerdfonts.custom_vim,
  ['vim'] = wezterm.nerdfonts.dev_vim,
  
  -- Container and Cloud Tools
  ['docker'] = wezterm.nerdfonts.linux_docker,
  ['docker-compose'] = wezterm.nerdfonts.linux_docker,
  ['kubectl'] = wezterm.nerdfonts.linux_docker,
  
  -- Utilities
  ['curl'] = wezterm.nerdfonts.md_waves,
  ['gh'] = wezterm.nerdfonts.dev_github_badge,
  ['make'] = wezterm.nerdfonts.seti_makefile,
  ['sudo'] = wezterm.nerdfonts.fa_hashtag,
  ['wget'] = wezterm.nerdfonts.md_arrow_down_box,
  ['lazygit'] = wezterm.nerdfonts.dev_github_alt,
}

Tab Settings

Configuration for tab-specific UI elements:

ui.tab = {
  zoom_indicator = {
    -- Enable zoom level indicator
    enabled = true,
    -- Display type of the zoom indicator
    type = 'icon',
  }
}

Usage

Once configured, the tab bar will automatically update with the relevant information when WezTerm is running.
