 # cli.go
+
 `cli.go` is simple, fast, and fun package for building command line apps in Go. The goal is to enable developers to write fast and distributable command line applications in an expressive way.
 
 ## Overview
+
 Command line apps are usually so tiny that there is absolutely no reason why your code should *not* be self-documenting. Things like generating help text and parsing command flags/options should not hinder productivity when writing a command line app.
 
 **This is where `cli.go` comes into play.** `cli.go` makes command line programming fun, organized, and expressive!
 
 ## Installation

 ## Contribution Guidelines
+
 Feel free to put up a pull request to fix a bug or maybe add a feature. I will give it a code review and make sure that it does not break backwards compatibility. If I or any other collaborators agree that it is in line with the vision of the project, we will work with you to get the code into a mergeable state and merge it into the master branch.
 
-If you have contributed something significant to the project, I will most likely add you as a collaborator. As a collaborator you are given the ability to merge others pull requests. It is very important that new code does not break existing code, so be careful about what code you do choose to merge. If you have any questions feel free to link @codegangsta to the issue in question and we can review it together.

-## Update 23/06/2015
+<img src="./_example/dashboard.gif" alt="demo cast under osx 10.10; Terminal.app; Menlo Regular 12pt.)" width="80%">
-Pull requests and master branch are freezing, waiting for merging from `refactoring` branch.
 
-## Notice
+`termui` is a cross-platform, easy-to-compile, and fully-customizable terminal dashboard. It is inspired by [blessed-contrib](https://github.com/yaronn/blessed-contrib), but purely in Go.
-termui comes with ABSOLUTELY NO WARRANTY, and there is a breaking change coming up (see refactoring branch) which will change the `Bufferer` interface and many others. These changes reduce calculation overhead and introduce a new drawing buffer with better capacibilities. We will step into the next stage (call it beta) after merging these changes.
 
-## Introduction
+Now version v2 has arrived! It brings new event system, new theme system, new `Buffer` interface and specific colour text rendering. (some docs are missing, but it will be completed soon!)
-Go terminal dashboard. Inspired by [blessed-contrib](https://github.com/yaronn/blessed-contrib), but purely in Go.
 
-Cross-platform, easy to compile, and fully-customizable.
+## Installation
 
-__Demo:__ (cast under osx 10.10; Terminal.app; Menlo Regular 12pt.)
+`master` mirrors v2 branch, to install:
 
-<img src="./example/dashboard.gif" alt="demo" width="600">
+	go get -u github.com/gizak/termui
+
+For the compatible reason, you can choose to install the legacy version of `termui`:
+
+	go get gopkg.in/gizak/termui.v1
+
+## Usage
+
+### Layout
+
+To use `termui`, the very first thing you may want to know is how to manage layout. `termui` offers two ways of doing this, known as absolute layout and grid layout.
+
+__Absolute layout__
+
+Each widget has an underlying block structure which basically is a box model. It has border, label and padding properties. A border of a widget can be chosen to hide or display (with its border label), you can pick a different front/back colour for the border as well. To display such a widget at a specific location in terminal window, you need to assign `.X`, `.Y`, `.Height`, `.Width` values for each widget before send it to `.Render`. Let's demonstrate these by a code snippet:
+
+`````go
+	import ui "github.com/gizak/termui" // <- ui shortcut, optional
+
+	func main() {
+		err := ui.Init()
+		if err != nil {
+			panic(err)
+		}
+		defer ui.Close()
+
+		p := ui.NewPar(":PRESS q TO QUIT DEMO")
+		p.Height = 3
+		p.Width = 50
+		p.TextFgColor = ui.ColorWhite
+		p.BorderLabel = "Text Box"
+		p.BorderFg = ui.ColorCyan
+
+		g := ui.NewGauge()
+		g.Percent = 50
+		g.Width = 50
+		g.Height = 3
+		g.Y = 11
+		g.BorderLabel = "Gauge"
+		g.BarColor = ui.ColorRed
+		g.BorderFg = ui.ColorWhite
+		g.BorderLabelFg = ui.ColorCyan
+
+		ui.Render(p, g) // feel free to call Render, it's async and non-block
+
+		// event handler...
+	}
+`````
+
+Note that components can be overlapped (I'd rather call this a feature...), `Render(rs ...Renderer)` renders its args from left to right (i.e. each component's weight is arising from left to right).

+
+Grid layout uses [12 columns grid system](http://www.w3schools.com/bootstrap/bootstrap_grid_system.asp) with expressive syntax. To use `Grid`, all we need to do is build a widget tree consisting of `Row`s and Cols (Actually a Col is also a `Row` but with a widget endpoint attached).

+### Events
 
-## Installation
+`termui` ships with a http-like event mux handling system. All events are channeled up from different sources (typing, click, windows resize, custom event) and then encoded as universal `Event` object. `Event.Path` indicates the event type and `Event.Data` stores the event data struct. Add a handler to a certain event is easy as below:
-
-	go get github.com/gizak/termui
-
-## Usage
-
-Each component's layout is a bit like HTML block (box model), which has border and padding.
-
-The `Border` property can be chosen to hide or display (with its border label), when it comes to display, the label takes 1 padding space (i.e. in css: `padding: 1;`, innerHeight and innerWidth therefore shrunk by 1).
-
-`````go
-	import ui "github.com/gizak/termui" // <- ui shortcut, optional
-
-	func main() {
-		err := ui.Init()
-		if err != nil {

-		g.BarColor = ui.ColorRed
-		g.Border.FgColor = ui.ColorWhite
-		g.Border.LabelFgColor = ui.ColorCyan
-
-		ui.Render(p, g)
-
-		// event handler...

-Note that components can be overlapped (I'd rather call this a feature...), `Render(rs ...Renderer)` renders its args from left to right (i.e. each component's weight is arising from left to right).
-
-## Themes
-
-_All_ colors in _all_ components can be changed at _any_ time, while there provides some predefined color schemes:
 
 ```go
-// for now there are only two themes: default and helloworld
+	// handle key q pressing
-termui.UseTheme("helloworld")
+	ui.Handle("/sys/kbd/q", func(ui.Event) {
+		// press q to quit
+		ui.StopLoop()
+	})
 
-// create components...
+	ui.Handle("/sys/kbd/C-x", func(ui.Event) {
+		// handle Ctrl + x combination
+	})
+
+	ui.Handle("/sys/kbd", func(ui.Event) {
+		// handle all other key pressing
+	})
+
+	// handle a 1s timer
+	ui.Handle("/timer/1s", func(e ui.Event) {
+		t := e.Data.(ui.EvtTimer)
+		// t is a EvtTimer
+		if t.Count%2 ==0 {
+			// do something
+		}
+	})
+
+	ui.Loop() // block until StopLoop is called
 ```
-The `default ` theme's settings depend on the user's terminal color scheme, which is saying if your terminal default font color is white and background is white, it will be like:
