CDK - Curses Development Kit

This package provides the GDK equivalent for CTK. This is not intended to be a parity of GDK in any way, rather this package simply fulfills the terminal drawing and basic event systems required by CTK.

Unless you're using CTK, you should really be using TCell instead.

Notice

This project should not be used for any purpose other than intellectual curiosity. This project, in its current iteration, is strictly a Proof-of-Concept and nothing more. The lessons learned so far are being incorporated into a clean rewrite of the entire thing.

This status is reflected in the tagged versioning of this trunk branch, v0.0.x, ie: entirely experimental and unfinished in any sense of the word "done".

Overview

CDK - Curses Development Kit

The Curses Development Kit is the low-level compliment to the higher-level Curses Tool Kit.

Introduction

CDK is based primarily upon the TCell codebase, however, it is a hard-fork with many API-breaking changes. Some of the more salient changes are as follows:

• `Screen` is now a `Display`
• `Theme` is a collection of purpose-intended `Style`s
• Developers are not intended to use the `Display` directly
• a `Canvas` type is used to composite the rendering process
• a `Window` type is used to render to a `Display` and handle events
• `EventFlag`s are used to manage the propagation of events
• robust canvas rendering enables reliable wrapping, justification and alignment of textual content
• `Tango` markup format to augment the text rendering with applied style attributes (with similar features as Pango for GDK/GTK)

CDK Demo Walkthrough

All CDK applications require some form of `Window` implementation in order to function. One can use the build-in `cdk.CWindow` type to construct a basic `Window` object and tie into it's signals in order to render to the canvas and handle events. For this example however, a more formal approach is taken.

type CdkDemoWindow struct {
    cdk.CWindow
}

Starting out with a very slim definition of our custom `Window`, all that's necessary is the embed the concrete `cdk.CWindow` type and proceed with overriding various methods.

func (w *CdkDemoWindow) Init() (already bool) {
    if w.CWindow.Init() {
        return true
    }
    return false
}

The `Init` method is not necessary to overload, however, this is a good spot to do any UI initializations or the like. For this demo, the boilerplate minimum is given as an example to start from.

func (w *CdkDemoWindow) Draw(canvas cdk.Canvas) cdk.EventFlag {
    ... things ...
}

The next method implemented is the `Draw` method. This method receives a pre-configured Canvas object, set to the available size of the `Display`. Within this method, the application needs to process as little "work" as possible and focus primarily on just rendering the content upon the canvas. Let's walk through each line of the `Draw` method.

w.LogInfo("Draw: %s", canvas)

This line uses the built-in logging facilities to log an "info" message that the `Draw` method was invoked and let's us know some sort of human-readable description of the canvas (resembles JSON text but isn't really JSON). The advantage to using these built-in logging facilities is that the log entry itself will be prefixed with some extra metadata identifying the particular object instance with a bit of text in the format of "typeName-ID" where typeName is the object's CDK-type and the ID is an integer (marking the unique instance).

theme := w.GetDisplayManager().DefaultTheme()

Within CDK, there is a concept of `Theme`, which really is just a collection of useful purpose-driven `Style`s. One can set the default theme for the running CDK system, however the stock state is either a monochrome base theme or a colorized variant. Some of the rendering functions require `Style`s or `Theme`s passed as arguments and so we're getting that here for later use.

size := canvas.Size()

Simply getting a `Rectangle` primitive with it's `W`idth and `H`eight values set according to the size of the canvas' internal buffer.

`Rectangle` is a CDK primitive which has just two fields: `W` and `H`. Most places where spacial bounds are necessary, these primitives are used (such as the concept of a box `size` for painting upon a canvas).

canvas.Box(cdk.Point2I{}, size, true, true, theme)

This is the first actual draw command. In this case, the `Box` method is configured to draw a box on the screen, starting at a position of 0,0 (top left corner), taking up the full volume of the canvas, with a border (first boolean `true` argument), ensuring to fill the entire area with the filler rune and style within a given theme, which is the last argument to the `Box` method. On a color-supporting terminal, this will paint a navy-blue box over the entire terminal screen.

content := "..."
content += "..."
content += "..."

These few lines of code are merely concatenating a string of `Tango` markup that includes use of `<b></b>`, `<u></u>`, `<i></i>`, and `<span></span>` tags. All colors have fallback versions and are typically safe even for monochrome terminal sessions.

textPoint := cdk.MakePoint2I(size.W/2/2, size.H/2-1)

This sets up a variable holding a `Point2I` instance configured for 1/4 of the width into the screen (from the left) and halfway minus one of the height into the screen (from the top).

`Point2I` is a CDK primitive which has just two fields: `X` and `Y`. Most places where coordinates are necessary, these primitives are used (such as the concept of an `origin` point for painting upon a canvas).

textSize := cdk.MakeRectangle(size.W/2, size.H/2)

This sets up a variable holding a `Rectangle` configured to be half the size of the canvas itself.

canvas.DrawText(textPoint, textSize, cdk.JUSTIFY_CENTER, false,
                cdk.WRAP_WORD, cdk.DefaultColorTheme.Normal, true,
                content)

This last command within the `Draw` method paints the textual-content prepared earlier onto the canvas provided, center-justified, wrapping on word boundaries, using the default `Normal` theme, specifying that the content is in fact to be parsed as `Tango` markup and finally the content itself.

The result of this drawing process should be a navy-blue screen, with a border, and three lines of text centered neatly. The three lines of text should be marked up with bold, italics, underlines and colorization. The last line of text should be telling the current time and date at the time of rendering.

func (w *CdkDemoWindow) ProcessEvent(evt cdk.Event) cdk.EventFlag {
    w.LogInfo("ProcessEvent: %v", evt)
    return cdk.EVENT_STOP
}

The `ProcessEvent` method is the main event handler. Whenever a new event is received by a CDK `Display`, it is passed on to the active `Window` and in this demonstration, all that's happening is a log entry is being made which mentions the event received.

When implementing your own `ProcessEvent` method, if the `Display` should repaint the screen for example, one would make two calls to methods on the `DisplayManager`:

w.GetDisplayManager().RequestDraw()
w.GetDisplayManager().RequestShow()

CDK is a multi-threaded framework and the various `Request*()` methods on the `DisplayManager` are used to funnel requests along the right channels in order to first render the canvas (via `Draw` calls on the active `Window`) and then follow that up with the running `Display` painting itself from the canvas modified in the `Draw` process.

The other complete list of request methods is as follows:

RequestDraw()  // window draw rendering
RequestShow()  // display rendering (modified cells only)
RequestSync()  // full display synchronization (all cells updated)
RequestQuit()  // graceful shutdown of a CDK `Display`

This concludes the `CdkDemoWindow` type implementation. Now on to using it!

The Main Func

The `main()` function within the `_demos/cdk-demo.go` sources is deceptively simple to implement.

app := cdk.NewApp(
    "cdk-demo",
    "An example of a formal CDK Application",
    "0.0.1",
    "demo",
    "CDK Demo",
    "/dev/tty",
    func(d cdk.DisplayManager) error {
        cdk.DebugF("cdk-demo initFn hit")
        d.CaptureCtrlC()
        w := &CdkDemoWindow{}
        w.Init()
        d.SetActiveWindow(w)
        cdk.AddTimeout(time.Second, func() cdk.EventFlag {
            d.RequestDraw()
            d.RequestShow()
            return cdk.EVENT_PASS // keep looping every second
        })
        return nil
    },
}

The bulk of the code is constructing a new CDK `App` instance. This object is a wrapper around the `github.com/urfave/cli/v2` CLI package, providing a tidy interface to managing CLI arguments, help documentation and so on. In this example, the `App` is configured with a bunch of metadata for: the program's name "cdk-demo", a simply usage summary, the current version number, an internally-used tag, a title for the main window and the display is to use the `/dev/tty` (default) terminal device.

Beyond the metadata, the final argument is an initialization function. This function receives a fully instantiated and running `Display` instance and it is expected that the application instantiates it's `Window` and sets it as the active window for the given `Display`.

In addition to that is one final call to `AddTimeout`. This call will trigger the given `func() cdk.EventFlag` once, after a second. Because the `func()` implemented here in this demonstration returns the `cdk.EVENT_PASS` flag it will be continually called once per second. For this demonstration, this implementation simply requests a draw and show cycle which will cause the screen to be repainted with the current date and time every second the demo application is running.

if err := app.Run(os.Args); err != nil {
    panic(err)
}

The final bit of code in this CDK demonstration simply passes the arguments provided by the end-user on the command-line in a call to the `App`'s `Run()` method. This will cause the `DisplayManager`, `Display` and other systems to instantiate and begin processing events and render cycles.

RuneFallbacks is the default map of fallback strings that will be used to replace a rune when no other more appropriate transformation is available, and the rune cannot be displayed directly.

New entries may be added to this map over time, as it becomes clear that such is desirable. Characters that represent either letters or numbers should not be added to this list unless it is certain that the meaning will still convey unambiguously.

As an example, it would be appropriate to add an ASCII mapping for the full width form of the letter 'A', but it would not be appropriate to do so a glyph representing the country China.

Programs that desire richer fallbacks may register additional ones, or change or even remove these mappings with Display.RegisterRuneFallback Display.UnregisterRuneFallback methods.

Note that Unicode is presumed to be able to display all glyphs. This is a pretty poor assumption, but there is no easy way to figure out which glyphs are supported in a given font. Hence, some care in selecting the characters you support in your application is still appropriate.

func RegisterEncoding

func RegisterEncoding(charset string, enc encoding.Encoding)

RegisterEncoding may be called by the application to register an encoding. The presence of additional encodings will facilitate application usage with terminal environments where the I/O subsystem does not support Unicode.

Windows systems use Unicode natively, and do not need any of the encoding subsystem when using Windows Console screens.

Please see the Go documentation for golang.org/x/text/encoding -- most of the common ones exist already as stock variables. For example, ISO8859-15 can be registered using the following code:

import "golang.org/x/text/encoding/charmap"

  ...
  RegisterEncoding("ISO8859-15", charmap.ISO8859_15)

Aliases can be registered as well, for example "8859-15" could be an alias for "ISO8859-15".

For POSIX systems, the cdk package will check the environment variables LC_ALL, LC_CTYPE, and LANG (in that order) to determine the character set. These are expected to have the following pattern:

$language[.$codeset[@$variant]

We extract only the $codeset part, which will usually be something like UTF-8 or ISO8859-15 or KOI8-R. Note that if the locale is either "POSIX" or "C", then we assume US-ASCII (the POSIX 'portable character set' and assume all other characters are somehow invalid.)

Modern POSIX systems and terminal emulators may use UTF-8, and for those systems, this API is also unnecessary. For example, Darwin (MacOS X) and modern Linux running modern xterm generally will out of the box without any of this. Use of UTF-8 is recommended when possible, as it saves quite a lot processing overhead.

Note that some encodings are quite large (for example GB18030 which is a superset of Unicode) and so the application size can be expected ot increase quite a bit as each encoding is added. The East Asian encodings have been seen to add 100-200K per encoding to the application size.

type ButtonMask

type ButtonMask int16

ButtonMask is a mask of mouse buttons and wheel events. Mouse button presses are normally delivered as both press and release events. Mouse wheel events are normally just single impulse events. Windows supports up to eight separate buttons plus all four wheel directions, but XTerm can only support mouse buttons 1-3 and wheel up/down. Its not unheard of for terminals to support only one or two buttons (think Macs). Old terminals, and true emulations (such as vt100) won't support mice at all, of course.

const (
	Button1 ButtonMask = 1 << iota // Usually left mouse button.
	Button2                        // Usually the middle mouse button.

type CanvasForEachFn

type CanvasForEachFn = func(x, y int, cell TextCell) EventFlag

func signature used when iterating over each cell

type CellBuffer

type CellBuffer struct {
	sync.Mutex
	// contains filtered or unexported fields
}

CellBuffer represents a two dimensional array of character cells. This is primarily intended for use by Display implementors; it contains much of the common code they need. To create one, just declare a variable of its type; no explicit initialization is necessary.

CellBuffer should be thread safe, original tcell is not.

func NewCellBuffer

func NewCellBuffer() *CellBuffer

func (*CellBuffer) Dirty

func (cb *CellBuffer) Dirty(x, y int) bool

Dirty checks if a character at the given location needs an to be refreshed on the physical display. This returns true if the cell content is different since the last time it was marked clean.

func (*CellBuffer) Fill

func (cb *CellBuffer) Fill(r rune, style Style)

Fill fills the entire cell buffer array with the specified character and style. Normally choose ' ' to clear the display. This API doesn't support combining characters, or characters with a width larger than one.

func (*CellBuffer) GetContent

func (cb *CellBuffer) GetContent(x, y int) (mainc rune, combc []rune, style Style, width int)

GetContent returns the contents of a character cell, including the primary rune, any combining character runes (which will usually be nil), the style, and the display width in cells. (The width can be either 1, normally, or 2 for East Asian full-width characters.)

func (*CellBuffer) Invalidate

func (cb *CellBuffer) Invalidate()

Invalidate marks all characters within the buffer as dirty.

func (*CellBuffer) Resize

func (cb *CellBuffer) Resize(w, h int)

Resize is used to resize the cells array, with different dimensions, while preserving the original contents. The cells will be invalidated so that they can be redrawn.

func (*CellBuffer) SetContent

func (cb *CellBuffer) SetContent(x int, y int, mainc rune, combc []rune, style Style)

SetContent sets the contents (primary rune, combining runes, and style) for a cell at a given location.

func (*CellBuffer) SetDirty

func (cb *CellBuffer) SetDirty(x, y int, dirty bool)

SetDirty is normally used to indicate that a cell has been displayed (in which case dirty is false), or to manually force a cell to be marked dirty.

func (*CellBuffer) Size

func (cb *CellBuffer) Size() (w, h int)

Size returns the (width, height) in cells of the buffer.

type Color

type Color uint64

Color represents a color. The low numeric values are the same as used by ECMA-48, and beyond that XTerm. A 24-bit RGB value may be used by adding in the ColorIsRGB flag. For Color names we use the W3C approved color names.

We use a 64-bit integer to allow future expansion if we want to add an 8-bit alpha, while still leaving us some room for extra options.

Note that on various terminals colors may be approximated however, or not supported at all. If no suitable representation for a color is known, the library will simply not set any color, deferring to whatever default attributes the terminal uses.

const (
	// ColorDefault is used to leave the Color unchanged from whatever
	// system or terminal default may exist.  It's also the zero value.
	ColorDefault Color = 0

	// ColorIsValid is used to indicate the color value is actually
	// valid (initialized).  This is useful to permit the zero value
	// to be treated as the default.
	ColorValid Color = 1 << 32

	// ColorIsRGB is used to indicate that the numeric value is not
	// a known color constant, but rather an RGB value.  The lower
	// order 3 bytes are RGB.
	ColorIsRGB Color = 1 << 33

	// ColorSpecial is a flag used to indicate that the values have
	// special meaning, and live outside of the color space(s).
	ColorSpecial Color = 1 << 34
)

func FindColor

func FindColor(c Color, palette []Color) Color

FindColor attempts to find a given color, or the best match possible for it, from the palette given. This is an expensive operation, so results should be cached by the caller.

func GetColor

func GetColor(name string) Color

GetColor creates a Color from a color name (W3C name). A hex value may be supplied as a string in the format "#ffffff".

func NewHexColor

func NewHexColor(v int32) Color

NewHexColor returns a color using the given 24-bit RGB value.

func NewRGBColor

func NewRGBColor(r, g, b int32) Color

NewRGBColor returns a new color with the given red, green, and blue values. Each value must be represented in the range 0-255.

func PaletteColor

func PaletteColor(index int) Color

PaletteColor creates a color based on the palette index.

func ParseColor

func ParseColor(name string) (c Color, ok bool)

GetColor creates a Color from a color name (W3C name). A hex value may be supplied as a string in the format "#ffffff".

func (Color) Hex

func (c Color) Hex() int32

Hex returns the color's hexadecimal RGB 24-bit value with each component consisting of a single byte, ala R << 16 | G << 8 | B. If the color is unknown or unset, -1 is returned.

func (Color) IsRGB

func (c Color) IsRGB() bool

IsRGB is true if the color is an RGB specific value.

func (Color) RGB

func (c Color) RGB() (int32, int32, int32)

RGB returns the red, green, and blue components of the color, with each component represented as a value 0-255. In the event that the color cannot be broken up (not set usually), -1 is returned for each value.

func (Color) String

func (c Color) String() string

Stringer interface implementation so the Color can be used in normal fmt operations without required the developer to jump any hoops.

func (Color) TrueColor

func (c Color) TrueColor() Color

TrueColor returns the true color (RGB) version of the provided color. This is useful for ensuring color accuracy when using named colors. This will override terminal theme colors.

func (Color) Valid

func (c Color) Valid() bool

Valid indicates the color is a valid value (has been set).

	// GetContent returns the contents at the given location.  If the
	// coordinates are out of range, then the values will be 0, nil,
	// StyleDefault.  Note that the contents returned are logical contents
	// and may not actually be what is displayed, but rather are what will
	// be displayed if Show() or Sync() is called.  The width is the width

	GetContent(x, y int) (mainc rune, combc []rune, style Style, width int)

	// SetContent sets the contents of the given cell location.  If

Display represents the physical (or emulated) display. This can be a terminal window or a physical console. Platforms implement this differently.

func NewConsoleDisplay

func NewConsoleDisplay() (Display, error)

NewConsoleDisplay returns a console based display. This platform doesn't have support for any, so it returns nil and a suitable error.

func NewDisplay

func NewDisplay() (Display, error)

NewDisplay returns a default Display suitable for the user's terminal environment.

func NewTerminfoDisplay

func NewTerminfoDisplay() (Display, error)

NewTerminfoDisplay returns a Display that uses the stock TTY interface and POSIX terminal control, combined with a terminfo description taken from the $TERM environment variable. It returns an error if the terminal is not supported for any reason.

For terminals that do not support dynamic resize events, the $LINES $COLUMNS environment variables can be set to the actual window size, otherwise defaults taken from the terminal database are used.

type EncodingFallback

type EncodingFallback int

EncodingFallback describes how the system behavees when the locale requires a character set that we do not support. The system always supports UTF-8 and US-ASCII. On Windows consoles, UTF-16LE is also supported automatically. Other character sets must be added using the RegisterEncoding API. (A large group of nearly all of them can be added using the RegisterAll function in the encoding sub package.)

type EnumFromString

type EnumFromString interface {
	FromString(value string) (enum interface{}, err error)
}

type Event

type Event interface {
	// When reports the time when the event was generated.
	When() time.Time
}

Event is a generic interface used for passing around Events. Concrete types follow.

type EventError

type EventError struct {
	// contains filtered or unexported fields
}

An EventError is an event representing some sort of error, and carries an error payload.

func NewEventError

func NewEventError(err error) *EventError

NewEventError creates an ErrorEvent with the given error payload.

func (*EventError) Clone

func (ev *EventError) Clone() *EventError

func (*EventError) Err

func (ev *EventError) Err() error

func (*EventError) Error

func (ev *EventError) Error() string

Error implements the error.

func (*EventError) When

func (ev *EventError) When() time.Time

When returns the time when the event was created.

type EventFlag

type EventFlag int

CEvent handling event flag type

const (
	EVENT_PASS EventFlag = iota // Allow other handlers to process
	EVENT_STOP                  // Prevent further event handling
)

CEvent handling event flags

type EventHandler

type EventHandler interface {
	HandleEvent(Event) bool
}

EventHandler is anything that handles events. If the handler has consumed the event, it should return true. False otherwise.

type EventInterrupt

type EventInterrupt struct {
	// contains filtered or unexported fields
}

EventInterrupt is a generic wakeup event. Its can be used to to request a redraw. It can carry an arbitrary payload, as well.

func NewEventInterrupt

func NewEventInterrupt(data interface{}) *EventInterrupt

NewEventInterrupt creates an EventInterrupt with the given payload.

func (*EventInterrupt) Data

func (ev *EventInterrupt) Data() interface{}

Data is used to obtain the opaque event payload.

func (*EventInterrupt) When

func (ev *EventInterrupt) When() time.Time

When returns the time when this event was created.

type EventKey

type EventKey struct {
	// contains filtered or unexported fields
}

EventKey represents a key press. Usually this is a key press followed by a key release, but since terminal programs don't have a way to report key release events, we usually get just one event. If a key is held down then the terminal may synthesize repeated key presses at some predefined rate. We have no control over that, nor visibility into it.

In some cases, we can have a modifier key, such as ModAlt, that can be generated with a key press. (This usually is represented by having the high bit set, or in some cases, by sending an ESC prior to the rune.)

If the value of Key() is KeyRune, then the actual key value will be available with the Rune() method. This will be the case for most keys. In most situations, the modifiers will not be set. For example, if the rune is 'A', this will be reported without the ModShift bit set, since really can't tell if the Shift key was pressed (it might have been CAPSLOCK, or a terminal that only can send capitals, or keyboard with separate capital letters from lower case letters).

Generally, terminal applications have far less visibility into keyboard activity than graphical applications. Hence, they should avoid depending overly much on availability of modifiers, or the availability of any specific keys.

func NewEventKey

func NewEventKey(k Key, ch rune, mod ModMask) *EventKey

NewEventKey attempts to create a suitable event. It parses the various ASCII control sequences if KeyRune is passed for Key, but if the caller has more precise information it should set that specifically. Callers that aren't sure about modifier state (most) should just pass ModNone.

func (*EventKey) Key

func (ev *EventKey) Key() Key

Key returns a virtual key code. We use this to identify specific key codes, such as KeyEnter, etc. Most control and function keys are reported with unique Key values. Normal alphanumeric and punctuation keys will generally return KeyRune here; the specific key can be further decoded using the Rune() function.

func (*EventKey) Modifiers

func (ev *EventKey) Modifiers() ModMask

Modifiers returns the modifiers that were present with the key press. Note that not all platforms and terminals support this equally well, and some cases we will not not know for sure. Hence, applications should avoid using this in most circumstances.

func (*EventKey) Name

func (ev *EventKey) Name() string

Name returns a printable value or the key stroke. This can be used when printing the event, for example.

func (*EventKey) Rune

func (ev *EventKey) Rune() rune

Rune returns the rune corresponding to the key press, if it makes sense. The result is only defined if the value of Key() is KeyRune.

func (*EventKey) When

func (ev *EventKey) When() time.Time

When returns the time when this Event was created, which should closely match the time when the key was pressed.

type EventMask

type EventMask uint64

const (
	EVENT_MASK_NONE EventMask = iota
	EVENT_MASK_KEY
	EVENT_MASK_MOUSE
	EVENT_MASK_PASTE
	EVENT_MASK_QUEUE
	EVENt_MASK_RESIZE
)

type EventMouse

type EventMouse struct {
	// contains filtered or unexported fields
}

EventMouse is a mouse event. It is sent on either mouse up or mouse down events. It is also sent on mouse motion events - if the terminal supports it. We make every effort to ensure that mouse release events are delivered. Hence, click drag can be identified by a motion event with the mouse down, without any intervening button release. On some terminals only the initiating press and terminating release event will be delivered.

Mouse wheel events, when reported, may appear on their own as individual impulses; that is, there will normally not be a release event delivered for mouse wheel movements.

Most terminals cannot report the state of more than one button at a time -- and some cannot report motion events unless a button is pressed.

Applications can inspect the time between events to resolve double or triple clicks.

func NewEventMouse

func NewEventMouse(x, y int, btn ButtonMask, mod ModMask) *EventMouse

NewEventMouse is used to create a new mouse event. Applications shouldn't need to use this; its mostly for display implementors.

type EventPaste

type EventPaste struct {
	// contains filtered or unexported fields
}

EventPaste is used to mark the start and end of a bracketed paste. An event with .MainInit() true will be sent to mark the start. Then a number of keys will be sent to indicate that the content is pasted in. At the end, an event with .MainInit() false will be sent.

func NewEventPaste(start bool) *EventPaste

NewEventPaste returns a new EventPaste.

func (*EventPaste) End

func (ev *EventPaste) End() bool

End returns true if this is the end of a paste.

type Key

type Key int16

Key is a generic value for representing keys, and especially special keys (function keys, cursor movement keys, etc.) For normal keys, like ASCII letters, we use KeyRune, and then expect the application to inspect the Rune() member of the EventKey.

const (

	KeyCtrlLeftSq // Escape
	KeyCtrlBackslash
	KeyCtrlRightSq

type ModMask int16

ModMask is a mask of modifier keys. Note that it will not always be possible to report modifier keys.

const (
	ModShift ModMask = 1 << iota
	ModCtrl
	ModAlt
	ModMeta
	ModNone ModMask = 0
)

These are the modifiers keys that can be sent either with a key press, or a mouse event. Note that as of now, due to the confusion associated with Meta, and the lack of support for it on many/most platforms, the current implementations never use it. Instead, they use ModAlt, even for events that could possibly have been distinguished from ModAlt.

	Style Style

	// Runes is the list of runes, unadulterated, in UTF-8.
	Runes []rune
}

OffscreenCell represents a simulated display cell. The purpose of this is to track on display content.

type OffscreenDisplay interface {
	// InjectKeyBytes injects a stream of bytes corresponding to
	// the native encoding (see charset).  It turns true if the entire
	// set of bytes were processed and delivered as KeyEvents, false
	// if any bytes were not fully understood.  Any bytes that are not
	// fully converted are discarded.
	InjectKeyBytes(buf []byte) bool

	// InjectKey injects a key event.  The rune is a UTF-8 rune, post
	// any translation.
	InjectKey(key Key, r rune, mod ModMask)

	// InjectMouse injects a mouse event.
	InjectMouse(x, y int, buttons ButtonMask, mod ModMask)

	// SetSize resizes the underlying physical display.  It also causes
	// a resize event to be injected during the next Show() or Sync().
	// A new physical contents array will be allocated (with data from
	// the old copied), so any prior value obtained with GetContents
	// won't be used anymore
	SetSize(width, height int)

	// GetContents returns display contents as an array of
	// cells, along with the physical width & height.   Note that the
	// physical contents will be used until the next time SetSize()
	// is called.
	GetContents() (cells []OffscreenCell, width int, height int)

	// GetCursor returns the cursor details.
	GetCursor() (x int, y int, visible bool)

	Display
