+# GOCUI - Go Console User Interface
+
+[![GoDoc](https://godoc.org/github.com/jroimartin/gocui?status.svg)](https://godoc.org/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.
+
+## Installation
+
+Execute:
+
+```
+$ go get github.com/jroimartin/gocui
+```
+
+## Documentation
+
+Execute:
+
+```
+$ go doc github.com/jroimartin/gocui
+```
+
+Or visit [godoc.org](https://godoc.org/github.com/jroimartin/gocui) to read it
+online.
+
+## Example
+
+```go
+package main
+
+import (
+ "fmt"
+ "log"
+
+ "github.com/jroimartin/gocui"
+)
+
+func main() {
+ g := gocui.NewGui()
+ if err := g.Init(); err != nil {
+ log.Panicln(err)
+ }
+ defer g.Close()
+
+ g.SetLayout(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
+}

+Package gocui allows to create console user interfaces.
+
+Create a new GUI:
+
+ g := gocui.NewGui()
+ if err := g.Init(); err != nil {
+ // handle error
+ }
+ defer g.Close()
+
+ // Set layout and key bindings
+ // ...
+
+ if err := g.MainLoop(); err != nil && err != gocui.ErrQuit {
+ // handle error
+ }
+
+Set the layout function:
+
+ g.SetLayout(fcn)
+
+On each iteration of the GUI's main loop, the "layout function" is executed.
+These layout functions can be used to set-up and update the application's main
+views, being possible to freely switch between them. Also, it is important to
+mention that a main loop iteration is executed on each reported event
+(key-press, mouse event, window resize, etc).
+
+GUIs are composed by Views, you can think of it as buffers. Views implement the
+io.ReadWriter interface, so you can just write to them if you want to modify
+their content. The same is valid for reading.
+
+Create and initialize a view with absolute coordinates:
+
+ if v, err := g.SetView("viewname", 2, 2, 22, 7); err != nil {
+ if err != gocui.ErrUnknownView {
+ // handle error
+ }
+ fmt.Fprintln(v, "This is a new view")
+ // ...
+ }
+
+Views can also be created using relative coordinates:
+
+ maxX, maxY := g.Size()
+ if v, err := g.SetView("viewname", maxX/2-30, maxY/2, maxX/2+30, maxY/2+2); err != nil {
+ // ...
+ }
+
+Configure keybindings:
+
+ if err := g.SetKeybinding("viewname", gocui.KeyEnter, gocui.ModNone, fcn); err != nil {
+ // handle error
+ }
+
+gocui implements full mouse support that can be enabled with:
+
+ g.Mouse = true
+
+Mouse events are handled like any other keybinding:
+
+ if err := g.SetKeybinding("viewname", gocui.MouseLeft, gocui.ModNone, fcn); err != nil {
+ // handle error
+ }
+
+IMPORTANT: Views can only be created, destroyed or updated in three ways: from
+layout functions, from keybinding callbacks or via *Gui.Execute(). The reason
+for this is that it allows gocui to be conccurent-safe. So, if you want to
+update your GUI from a goroutine, you must use *Gui.Execute(). For example:
+
+ g.Execute(func(g *gocui.Gui) error {
+ v, err := g.View("viewname")
+ if err != nil {
+ // handle error
+ }
+ v.Clear()
+ fmt.Fprintln(v, "Writing from different goroutines")
+ return nil
+ })
+
+By default, gocui provides a basic edition mode. This mode can be extended
+and customized creating a new Editor and assigning it to *Gui.Editor:
+
+ type Editor interface {
+ Edit(v *View, key Key, ch rune, mod Modifier)
+ }
+
+DefaultEditor can be taken as example to create your own custom Editor:
+
+ var DefaultEditor Editor = EditorFunc(simpleEditor)
+
+ func simpleEditor(v *View, key Key, ch rune, mod Modifier) {
+ switch {
+ case ch != 0 && mod == 0:
+ v.EditWrite(ch)
+ case key == KeySpace:
+ v.EditWrite(' ')
+ case key == KeyBackspace || key == KeyBackspace2:
+ v.EditDelete(true)
+ // ...
+ }
+ }
+
+Colored text:
+
+Views allow to add colored text using ANSI colors. For example:
+
+ fmt.Fprintln(v, "\x1b[0;31mHello world")
+
+For more information, see the examples in folder "_examples/".

+## Termbox
+Termbox is a library that provides a minimalistic API which allows the programmer to write text-based user interfaces. The library is crossplatform and has both terminal-based implementations on *nix operating systems and a winapi console based implementation for windows operating systems. The basic idea is an abstraction of the greatest common subset of features available on all major terminals and other terminal-like APIs in a minimalistic fashion. Small API means it is easy to implement, test, maintain and learn it, that's what makes the termbox a distinct library in its area.
+
+### Installation
+Install and update this go package with `go get -u github.com/nsf/termbox-go`
+
+### Examples
+For examples of what can be done take a look at demos in the _demos directory. You can try them with go run: `go run _demos/keyboard.go`
