# GOCUI - Go Console User Interface

[![Go Reference](https://pkg.go.dev/badge/github.com/jroimartin/gocui.svg)](https://pkg.go.dev/github.com/jroimartin/gocui)

Minimalist Go package aimed at creating Console User Interfaces.

## Features

* Minimalist API.
* Views (the "windows" in the GUI) implement the interface io.ReadWriter.
* Support for overlapping views.
* The GUI can be modified at runtime (concurrent-safe).
* Global and view-level keybindings.
* Mouse support.
* Colored text.
* Customizable edition mode.
* Easy to build reusable widgets, complex layouts...

## Installation

Execute:

```sh
go get github.com/jroimartin/gocui
```

## Documentation

Execute:

```sh
go doc github.com/jroimartin/gocui
```

Or visit [pkg.go.dev](https://pkg.go.dev/github.com/jroimartin/gocui) to read
it online.

## Example

```go
package main

import (
"fmt"
"log"

"github.com/jroimartin/gocui"
)

func main() {
g, err := gocui.NewGui(gocui.OutputNormal)
if err != nil {
log.Panicln(err)
}
defer g.Close()

g.SetManagerFunc(layout)

if err := g.SetKeybinding("", gocui.KeyCtrlC, gocui.ModNone, quit); err != nil {
log.Panicln(err)
}

if err := g.MainLoop(); err != nil && err != gocui.ErrQuit {
log.Panicln(err)
}
}

func layout(g *gocui.Gui) error {
maxX, maxY := g.Size()
if v, err := g.SetView("hello", maxX/2-7, maxY/2, maxX/2+7, maxY/2+2); err != nil {
if err != gocui.ErrUnknownView {
return err
}
fmt.Fprintln(v, "Hello world!")
}
return nil
}

func quit(g *gocui.Gui, v *gocui.View) error {
return gocui.ErrQuit
}
```
