+Package cl provides a binding to the OpenCL api. It's mostly a low-level
+wrapper that avoids adding functionality while still making the interface
+a little more friendly and easy to use.
+
+Resource life-cycle management:
+
+For any CL object that gets created (buffer, queue, kernel, etc..) you should
+call object.Release() when finished with it to free the CL resources. This
+explicitely calls the related clXXXRelease method for the type. However,
+as a fallback there is a finalizer set for every resource item that takes
+care of it (eventually) if Release isn't called. In this way you can have
+better control over the life cycle of resources while having a fall back
+to avoid leaks. This is similar to how file handles and such are handled
+in the Go standard packages.

+Package spew implements a deep pretty printer for Go data structures to aid in
+debugging.
+
+A quick overview of the additional features spew provides over the built-in
+printing facilities for Go data types are as follows:
+
+	* Pointers are dereferenced and followed
+	* Circular data structures are detected and handled properly
+	* Custom Stringer/error interfaces are optionally invoked, including
+	  on unexported types
+	* Custom types which only implement the Stringer/error interfaces via
+	  a pointer receiver are optionally invoked when passing non-pointer
+	  variables
+	* Byte arrays and slices are dumped like the hexdump -C command which
+	  includes offsets, byte values in hex, and ASCII output (only when using
+	  Dump style)
+
+There are two different approaches spew allows for dumping Go data structures:
+
+	* Dump style which prints with newlines, customizable indentation,
+	  and additional debug information such as types and all pointer addresses
+	  used to indirect to the final value
+	* A custom Formatter interface that integrates cleanly with the standard fmt
+	  package and replaces %v, %+v, %#v, and %#+v to provide inline printing
+	  similar to the default %v while providing the additional functionality
+	  outlined above and passing unsupported format verbs such as %x and %q
+	  along to fmt
+
+Quick Start
+
+This section demonstrates how to quickly get started with spew.  See the
+sections below for further details on formatting and configuration options.
+
+To dump a variable with full newlines, indentation, type, and pointer
+information use Dump, Fdump, or Sdump:
+	spew.Dump(myVar1, myVar2, ...)
+	spew.Fdump(someWriter, myVar1, myVar2, ...)
+	str := spew.Sdump(myVar1, myVar2, ...)
+
+Alternatively, if you would prefer to use format strings with a compacted inline
+printing style, use the convenience wrappers Printf, Fprintf, etc with
+%v (most compact), %+v (adds pointer addresses), %#v (adds types), or
+%#+v (adds types and pointer addresses):
+	spew.Printf("myVar1: %v -- myVar2: %+v", myVar1, myVar2)
+	spew.Printf("myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
+	spew.Fprintf(someWriter, "myVar1: %v -- myVar2: %+v", myVar1, myVar2)
+	spew.Fprintf(someWriter, "myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
+
+Configuration Options
+
+Configuration of spew is handled by fields in the ConfigState type.  For
+convenience, all of the top-level functions use a global state available
+via the spew.Config global.
+
+It is also possible to create a ConfigState instance that provides methods
+equivalent to the top-level functions.  This allows concurrent configuration
+options.  See the ConfigState documentation for more details.
+
+The following configuration options are available:
+	* Indent
+		String to use for each indentation level for Dump functions.
+		It is a single space by default.  A popular alternative is "\t".
+
+	* MaxDepth
+		Maximum number of levels to descend into nested data structures.
+		There is no limit by default.
+
+	* DisableMethods
+		Disables invocation of error and Stringer interface methods.
+		Method invocation is enabled by default.
+
+	* DisablePointerMethods
+		Disables invocation of error and Stringer interface methods on types
+		which only accept pointer receivers from non-pointer variables.
+		Pointer method invocation is enabled by default.
+
+	* ContinueOnMethod
+		Enables recursion into types after invoking error and Stringer interface
+		methods. Recursion after method invocation is disabled by default.
+
+	* SortKeys
+		Specifies map keys should be sorted before being printed. Use
+		this to have a more deterministic, diffable output.  Note that
+		only native types (bool, int, uint, floats, uintptr and string)
+		and types which implement error or Stringer interfaces are
+		supported with other types sorted according to the
+		reflect.Value.String() output which guarantees display
+		stability.  Natural map order is used by default.
+
+	* SpewKeys
+		Specifies that, as a last resort attempt, map keys should be
+		spewed to strings and sorted by those strings.  This is only
+		considered if SortKeys is true.
+
+Dump Usage
+
+Simply call spew.Dump with a list of variables you want to dump:
+
+	spew.Dump(myVar1, myVar2, ...)
+
+You may also call spew.Fdump if you would prefer to output to an arbitrary
+io.Writer.  For example, to dump to standard error:
+

+
+Custom Formatter
+
+Spew provides a custom formatter that implements the fmt.Formatter interface
+so that it integrates cleanly with standard fmt package printing functions. The
+formatter is useful for inline printing of smaller data types similar to the
+standard %v format specifier.
+
+The custom formatter only responds to the %v (most compact), %+v (adds pointer
+addresses), %#v (adds types), or %#+v (adds types and pointer addresses) verb
+combinations.  Any other verbs such as %x and %q will be sent to the the
+standard fmt package for formatting.  In addition, the custom formatter ignores
+the width and precision arguments (however they will still work on the format
+specifiers not handled by the custom formatter).
+
+Custom Formatter Usage
+
+The simplest way to make use of the spew custom formatter is to call one of the
+convenience functions such as spew.Printf, spew.Println, or spew.Printf.  The
+functions have syntax you are most likely already familiar with:
+
+	spew.Printf("myVar1: %v -- myVar2: %+v", myVar1, myVar2)
+	spew.Printf("myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
+	spew.Println(myVar, myVar2)
+	spew.Fprintf(os.Stderr, "myVar1: %v -- myVar2: %+v", myVar1, myVar2)
+	spew.Fprintf(os.Stderr, "myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
+
+See the Index for the full list convenience functions.
+
+Sample Formatter Output
+
+Double pointer to a uint8:
+	  %v: <**>5
+	 %+v: <**>(0xf8400420d0->0xf8400420c8)5
+	 %#v: (**uint8)5
+	%#+v: (**uint8)(0xf8400420d0->0xf8400420c8)5
+
+Pointer to circular struct with a uint8 field and a pointer to itself:
+	  %v: <*>{1 <*><shown>}
+	 %+v: <*>(0xf84003e260){ui8:1 c:<*>(0xf84003e260)<shown>}
+	 %#v: (*main.circular){ui8:(uint8)1 c:(*main.circular)<shown>}
+	%#+v: (*main.circular)(0xf84003e260){ui8:(uint8)1 c:(*main.circular)(0xf84003e260)<shown>}
+
+See the Printf example for details on the setup of variables being shown
+here.
+
+Errors
+
+Since it is possible for custom Stringer/error interfaces to panic, spew
+detects them and handles them internally by printing the panic information
+inline with the output.  Since spew is intended to provide deep pretty printing
+capabilities on structures, it intentionally does not return any errors.

+
+
+
+Color lets you use colorized outputs in terms of [ANSI Escape Codes](http://en.wikipedia.org/wiki/ANSI_escape_code#Colors) in Go (Golang). It has support for Windows too! The API can be used in several ways, pick one that suits you.
+
+

+
+
+## Install
+
+```bash
+go get github.com/fatih/color
+```
+
+## Examples
+
+### Standard colors
+
+```go
+// Print with default helper functions
+color.Cyan("Prints text in cyan.")
+
+// A newline will be appended automatically
+color.Blue("Prints %s in blue.", "text")
+
+// These are using the default foreground colors
+color.Red("We have red")
+color.Magenta("And many others ..")
+
+```
+
+### Mix and reuse colors
+
+```go
+// Create a new color object
+c := color.New(color.FgCyan).Add(color.Underline)
+c.Println("Prints cyan text with an underline.")
+
+// Or just add them to New()
+d := color.New(color.FgCyan, color.Bold)
+d.Printf("This prints bold cyan %s\n", "too!.")
+
+// Mix up foreground and background colors, create new mixes!
+red := color.New(color.FgRed)
+
+boldRed := red.Add(color.Bold)
+boldRed.Println("This will print text in bold red.")
+
+whiteBackground := red.Add(color.BgWhite)
+whiteBackground.Println("Red text with white background.")
+```
+
+### Custom print functions (PrintFunc)
+
+```go
+// Create a custom print function for convenience
+red := color.New(color.FgRed).PrintfFunc()
+red("Warning")
+red("Error: %s", err)
+
+// Mix up multiple attributes
+notice := color.New(color.Bold, color.FgGreen).PrintlnFunc()
+notice("Don't forget this...")
+```
+
+### Insert into noncolor strings (SprintFunc)
+
+```go
+// Create SprintXxx functions to mix strings with other non-colorized strings:
+yellow := color.New(color.FgYellow).SprintFunc()
+red := color.New(color.FgRed).SprintFunc()
+fmt.Printf("This is a %s and this is %s.\n", yellow("warning"), red("error"))
+
+info := color.New(color.FgWhite, color.BgGreen).SprintFunc()
+fmt.Printf("This %s rocks!\n", info("package"))
+
+// Use helper functions
+fmt.Printf("This", color.RedString("warning"), "should be not neglected.")
+fmt.Printf(color.GreenString("Info:"), "an important message." )
+
+// Windows supported too! Just don't forget to change the output to color.Output
+fmt.Fprintf(color.Output, "Windows support: %s", color.GreenString("PASS"))
+```
+
+### Plug into existing code
+
+```go
+// Use handy standard colors
+color.Set(color.FgYellow)
+
+fmt.Println("Existing text will now be in yellow")
+fmt.Printf("This one %s\n", "too")
+
+color.Unset() // Don't forget to unset
+
+// You can mix up parameters
+color.Set(color.FgMagenta, color.Bold)
+defer color.Unset() // Use it in your function
+
+fmt.Println("All text will now be bold magenta.")
+```
+
+### Disable color
+
+There might be a case where you want to disable color output (for example to
+pipe the standard output of your app to somewhere else). `Color` has support to
+disable colors both globally and for single color definition. For example
+suppose you have a CLI app and a `--no-color` bool flag. You can easily disable
+the color output with:
+
+```go
+
+var flagNoColor = flag.Bool("no-color", false, "Disable color output")
+
+if *flagNoColor {
+	color.NoColor = true // disables colorized output
+}
+```
+
+It also has support for single color definitions (local). You can
+disable/enable color output on the fly:
+
+```go
+c := color.New(color.FgCyan)
+c.Println("Prints cyan text")
+
+c.DisableColor()
+c.Println("This is printed without any color")
+
+c.EnableColor()
+c.Println("This prints again cyan...")
+```

+Package color is an ANSI color package to output colorized or SGR defined
+output to the standard output. The API can be used in several way, pick one
+that suits you.
+
+Use simple and default helper functions with predefined foreground colors:
+
+    color.Cyan("Prints text in cyan.")
+
+    // a newline will be appended automatically
+    color.Blue("Prints %s in blue.", "text")
+
+    // More default foreground colors..
+    color.Red("We have red")
+    color.Yellow("Yellow color too!")
+    color.Magenta("And many others ..")
+
+However there are times where custom color mixes are required. Below are some
+examples to create custom color objects and use the print functions of each
+separate color object.
+
+    // Create a new color object
+    c := color.New(color.FgCyan).Add(color.Underline)
+    c.Println("Prints cyan text with an underline.")
+
+    // Or just add them to New()
+    d := color.New(color.FgCyan, color.Bold)
+    d.Printf("This prints bold cyan %s\n", "too!.")
+
+
+    // Mix up foreground and background colors, create new mixes!
+    red := color.New(color.FgRed)
+
+    boldRed := red.Add(color.Bold)
+    boldRed.Println("This will print text in bold red.")
+
+    whiteBackground := red.Add(color.BgWhite)
+    whiteBackground.Println("Red text with White background.")
+
+
+You can create PrintXxx functions to simplify even more:
+
+    // Create a custom print function for convenient
+    red := color.New(color.FgRed).PrintfFunc()
+    red("warning")
+    red("error: %s", err)
+
+    // Mix up multiple attributes
+    notice := color.New(color.Bold, color.FgGreen).PrintlnFunc()
+    notice("don't forget this...")
+
+
+Or create SprintXxx functions to mix strings with other non-colorized strings:
+
+    yellow := New(FgYellow).SprintFunc()
+    red := New(FgRed).SprintFunc()
+
+    fmt.Printf("this is a %s and this is %s.\n", yellow("warning"), red("error"))
+
+    info := New(FgWhite, BgGreen).SprintFunc()
+    fmt.Printf("this %s rocks!\n", info("package"))
+
+Windows support is enabled by default. All Print functions works as intended.
+However only for color.SprintXXX functions, user should use fmt.FprintXXX and
+set the output to color.Output:
+
+    fmt.Fprintf(color.Output, "Windows support: %s", color.GreenString("PASS"))
+
+    info := New(FgWhite, BgGreen).SprintFunc()
+    fmt.Fprintf(color.Output, "this %s rocks!\n", info("package"))
+
+Using with existing code is possible. Just use the Set() method to set the
+standard output to the given parameters. That way a rewrite of an existing
+code is not required.
+
+    // Use handy standard colors.
+    color.Set(color.FgYellow)
+
+    fmt.Println("Existing text will be now in Yellow")
+    fmt.Printf("This one %s\n", "too")
+
+    color.Unset() // don't forget to unset
+
+    // You can mix up parameters
+    color.Set(color.FgMagenta, color.Bold)
+    defer color.Unset() // use it in your function
+
+    fmt.Println("All text will be now bold magenta.")
+
+There might be a case where you want to disable color output (for example to
+pipe the standard output of your app to somewhere else). `Color` has support to
+disable colors both globally and for single color definition. For example
+suppose you have a CLI app and a `--no-color` bool flag. You can easily disable

+
+    if *flagNoColor {
+    	color.NoColor = true // disables colorized output
+    }
+
+It also has support for single color definitions (local). You can
+disable/enable color output on the fly:
+
+     c := color.New(color.FgCyan)
+     c.Println("Prints cyan text")
+
+     c.DisableColor()
+     c.Println("This is printed without any color")
+
+     c.EnableColor()

+
+`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.
+
+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!)
+
+## Installation
+
+`master` mirrors v2 branch, to install:
+
+	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:__
+
+<img src="./_example/grid.gif" alt="grid" width="60%">
+
+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).
+
+```go
+	import ui "github.com/gizak/termui"
+	// init and create widgets...
+
+	// build
+	ui.Body.AddRows(
+		ui.NewRow(
+			ui.NewCol(6, 0, widget0),
+			ui.NewCol(6, 0, widget1)),
+		ui.NewRow(
+			ui.NewCol(3, 0, widget2),
+			ui.NewCol(3, 0, widget30, widget31, widget32),
+			ui.NewCol(6, 0, widget4)))
+
+	// calculate layout
+	ui.Body.Align()
+
+	ui.Render(ui.Body)
+```
+
+### Events
+
+`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
+	// handle key q pressing
+	ui.Handle("/sys/kbd/q", func(ui.Event) {
+		// press q to quit
+		ui.StopLoop()
+	})
+
+	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
+```
