Configure Wezterm on Windows for WSL

Introduction

Windows Terminal can feel sluggish inside WSL; Wezterm is a good alternative with many of the built-in features and still felling more responsive.

Install

Install Wezterm using winget

Winget:

winget install -e --id wez.wezterm

Configure Fonts

Install Nerd Fonts for maximum compatibility with Wezterm configuration:

The easiest way is to install it using scoop:

scoop bucket add nerd-fonts
scoop install nerd-fonts/JetBrainsMono-NF

Configure Wezterm

Drop the following config into C:\Users\<you>\.wezterm.lua:

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

local config = {}
local keys = {}
local mouse_bindings = {}
local launch_menu = {}

if wezterm.config_builder then
  config = wezterm.config_builder()
end

config.font = wezterm.font('JetBrainsMono Nerd Font')
config.font_size = 11
config.launch_menu = launch_menu
config.disable_default_key_bindings = true
config.mouse_bindings = mouse_bindings

config.default_domain = 'WSL:Ubuntu'

return config

Run Wezterm

Now, once you open Wezterm, WSL Ubuntu distribution will be open automatically if configured.

You can change config.default_domain = 'WSL:Ubuntu' to any distribution you have installed if you prefer.
