Go Report Card Build Status Godoc Card

Cross platform rapid GUI framework for golang based on Dear ImGui and the great golang binding imgui-go.

Any contribution (features, widgets, tutorials, documents and etc...) is appreciated!

Supported Platforms

giu is built upon GLFW v3.3, so idealy giu could support all platforms that GLFW v3.3 supports.

  • Windows (only tested on Windows 10 x64)
  • MacOS (only tested on MacOS v10.15)
  • Linux (thanks remeh to test it)
  • Raspberry pi 3b (thanks sndvaps to test it)

Features

Compare to other Dear ImGui golang bindings, giu has following features:

  • Small executable file size (<3mb after upx compression for the example/helloworld demo).
  • Live-update during the resizing of OS window (implemented on GLFW 3.3 and OpenGL 3.2).
  • Redraw only when user event occurred. Costs only 0.5% CPU usage with 60FPS.
  • Declarative UI (see examples for more detail).
  • DPI awareness (auto scale font and UI to adapte high DPI monitor).
  • Drop in usage, no need to implement render and platform.
  • Freetype font rendering support.
  • OS clipboard support.

Hello world

package main

import (
    "fmt"

    g "github.com/AllenDang/giu"
)

func onClickMe() {
    fmt.Println("Hello world!")
}

func onImSoCute() {
    fmt.Println("Im sooooooo cute!!")
}

func loop() {
    g.SingleWindow("hello world", g.Layout{
        g.Label("Hello world from giu"),
        g.Line(
            g.Button("Click Me", onClickMe),
            g.Button("I'm so cute", onImSoCute)),
        })
}

func main() {
    wnd := g.NewMasterWindow("Hello world", 400, 200, g.MasterWindowFlagsNotResizable, nil)
    wnd.Main(loop)
}

Here is result.

Embed Lua as script language to create UI

This is a very interesting use case and it is incredibly easy.

package main

import (
	g "github.com/AllenDang/giu"
	lua "github.com/yuin/gopher-lua"
	luar "layeh.com/gopher-luar"
)

// Define a simple plugin struct
type LuaPlugin struct {
	Name   string
	Layout g.Layout
}

// Genreate a string pointer for lua
func GStrPtr() *string {
	var str string
	return &str
}

// Receive string value from pointer
func ToStr(str *string) string {
	return *str
}

var luaPlugin LuaPlugin

func onRunScript() {
	luaPlugin.Name = ""
	luaPlugin.Layout = g.Layout{}

	luaState := lua.NewState()
	defer luaState.Close()

	// Pass luaPlugin into lua VM.
	luaState.SetGlobal("luaPlugin", luar.New(luaState, &luaPlugin))

	// Register some method (giu widget creator)
	luaState.SetGlobal("GStrPtr", luar.New(luaState, GStrPtr))
	luaState.SetGlobal("ToStr", luar.New(luaState, ToStr))

	luaState.SetGlobal("Label", luar.New(luaState, g.Label))
	luaState.SetGlobal("Button", luar.New(luaState, g.Button))
	luaState.SetGlobal("InputText", luar.New(luaState, g.InputText))

	// Simple lua code
	luaCode := `
    luaPlugin.Name = "test"

    name = GStrPtr()
    
    function onGreeting()
	  print(string.format("Greeting %s", ToStr(name)))
    end
    
    luaPlugin.Layout = {
      Label("Label from lua, tell me your name"),
      InputText("##name", 200, name),
      Button("Greeting", onGreeting),
    }
  `

	// Run lua script
	if err := luaState.DoString(luaCode); err != nil {
		panic(err)
	}
}

func loop() {
	g.SingleWindow("Lua test", g.Layout{
		g.Button("Load from lua", onRunScript),
		luaPlugin.Layout,
	})
}

func main() {
	wnd := g.NewMasterWindow("Lua test", 400, 300, 0, nil)
	wnd.Main(loop)
}
