-# clipboard [![PkgGoDev](https://pkg.go.dev/badge/golang.design/x/clipboard)](https://pkg.go.dev/golang.design/x/clipboard) ![](https://changkun.de/urlstat?mode=github&repo=golang-design/clipboard) ![clipboard](https://github.com/golang-design/clipboard/workflows/clipboard/badge.svg?branch=main)
-
-Cross platform (macOS/Linux/Windows/Android/iOS) clipboard package in Go
-
-```go
-import "golang.design/x/clipboard"
-```
-
-## Features
-
-- Cross platform supports: **macOS, Linux (X11), Windows, iOS, and Android**
-- Copy/paste UTF-8 text
-- Copy/paste PNG encoded images (Desktop-only)
-- Command `gclip` as a demo application
-- Mobile app `gclip-gui` as a demo application
-
-## API Usage
-
-Package clipboard provides cross platform clipboard access and supports
-macOS/Linux/Windows/Android/iOS platform. Before interacting with the
-clipboard, one must call Init to assert if it is possible to use this
-package:
-
-```go
-// Init returns an error if the package is not ready for use.
-err := clipboard.Init()
-if err != nil {
-      panic(err)
-}
-```
-
-The most common operations are `Read` and `Write`. To use them:
-
-```go
-// write/read text format data of the clipboard, and
-// the byte buffer regarding the text are UTF8 encoded.
-clipboard.Write(clipboard.FmtText, []byte("text data"))
-clipboard.Read(clipboard.FmtText)
-
-// write/read image format data of the clipboard, and
-// the byte buffer regarding the image are PNG encoded.
-clipboard.Write(clipboard.FmtImage, []byte("image data"))
-clipboard.Read(clipboard.FmtImage)
-```
-
-Note that read/write regarding image format assumes that the bytes are
-PNG encoded since it serves the alpha blending purpose that might be
-used in other graphical software.
-
-In addition, `clipboard.Write` returns a channel that can receive an
-empty struct as a signal, which indicates the corresponding write call
-to the clipboard is outdated, meaning the clipboard has been overwritten
-by others and the previously written data is lost. For instance:
-
-```go
-changed := clipboard.Write(clipboard.FmtText, []byte("text data"))
-
-select {
-case <-changed:
-      println(`"text data" is no longer available from clipboard.`)
-}
-```
-
-You can ignore the returning channel if you don't need this type of
-notification. Furthermore, when you need more than just knowing whether
-clipboard data is changed, use the watcher API:
-
-```go
-ch := clipboard.Watch(context.TODO(), clipboard.FmtText)
-for data := range ch {
-      // print out clipboard data whenever it is changed
-      println(string(data))
-}
-```
-
-## Demos
-
-- A command line tool `gclip` for command line clipboard accesses, see document [here](./cmd/gclip/README.md).
-- A GUI application `gclip-gui` for functionality verifications on mobile systems, see a document [here](./cmd/gclip-gui/README.md).
-
-
-## Command Usage
-
-`gclip` command offers the ability to interact with the system clipboard
-from the shell. To install:
-
-```bash
-$ go install golang.design/x/clipboard/cmd/gclip@latest
-```
-
-```bash
-$ gclip
-gclip is a command that provides clipboard interaction.
-
-usage: gclip [-copy|-paste] [-f <file>]
-
-options:
-  -copy
-        copy data to clipboard
-  -f string
-        source or destination to a given file path
-  -paste
-        paste data from clipboard
-
-examples:
-gclip -paste                    paste from clipboard and prints the content
-gclip -paste -f x.txt           paste from clipboard and save as text to x.txt
-gclip -paste -f x.png           paste from clipboard and save as image to x.png
-
-cat x.txt | gclip -copy         copy content from x.txt to clipboard
-gclip -copy -f x.txt            copy content from x.txt to clipboard
-gclip -copy -f x.png            copy x.png as image data to clipboard
-```
-
-If `-copy` is used, the command will exit when the data is no longer
-available from the clipboard. You can always send the command to the
-background using a shell `&` operator, for example:
-
-```bash
-$ cat x.txt | gclip -copy &
-```
-
-## Platform Specific Details
-
-This package spent efforts to provide cross platform abstraction regarding
-accessing system clipboards, but here are a few details you might need to know.
-
-### Dependency
-
-- macOS: require Cgo, no dependency
- - Linux: require X11 dev package. For instance, install `libx11-dev` or `xorg-dev` or `libX11-devel` to access X window system.
-   Wayland sessions are currently unsupported; running under Wayland
-   typically requires an XWayland bridge and `DISPLAY` to be set.
-- Windows: no Cgo, no dependency
-- iOS/Android: collaborate with [`gomobile`](https://golang.org/x/mobile)
-
-### Screenshot
-
-In general, when you need test your implementation regarding images,
-There are system level shortcuts to put screenshot image into your system clipboard:
-
-- On macOS, use `Ctrl+Shift+Cmd+4`
-- On Linux/Ubuntu, use `Ctrl+Shift+PrintScreen`
-- On Windows, use `Shift+Win+s`
-
-As described in the API documentation, the package supports read/write
-UTF8 encoded plain text or PNG encoded image data. Thus,
-the other types of data are not supported yet, i.e. undefined behavior.
-
-## Who is using this package?
-
-The main purpose of building this package is to support the
-[midgard](https://changkun.de/s/midgard) project, which offers
-clipboard-based features like universal clipboard service that syncs
-clipboard content across multiple systems, allocating public accessible
-for clipboard content, etc.

-# gclip-gui
-
-This is a very basic example for verification purpose that demonstrates
-how the [golang.design/x/clipboard](https://golang.design/x/clipboard)
-can interact with macOS/Linux/Windows/Android/iOS system clipboard.
-
-The gclip GUI application writes a string to the system clipboard
-periodically then reads it back and renders it if possible.
-
-Because of the system limitation, on mobile devices, only string data is
-supported at the moment. Hence, one must use clipboard.FmtText. Other supplied
-formats result in a panic.
-
-This example is intentded as cross platform application. To build it, one
-must use [gomobile](https://golang.org/x/mobile). You may follow the instructions
-provided in the [GoMobile wiki](https://github.com/golang/go/wiki/Mobile) page.

-# gclip
-
-`gclip` command offers the ability to interact with the system clipboard
-from the shell. To install:
-
-```bash
-$ go install golang.design/x/clipboard/cmd/gclip@latest
-```
-
-```bash
-$ gclip
-gclip is a command that provides clipboard interaction.
-usage: gclip [-copy|-paste] [-f <file>]
-options:
-  -copy
-        copy data to clipboard
-  -f string
-        source or destination to a given file path
-  -paste
-        paste data from clipboard
-examples:
-gclip -paste                    paste from clipboard and prints the content
-gclip -paste -f x.txt           paste from clipboard and save as text to x.txt
-gclip -paste -f x.png           paste from clipboard and save as image to x.png
-cat x.txt | gclip -copy         copy content from x.txt to clipboard
-gclip -copy -f x.txt            copy content from x.txt to clipboard
-gclip -copy -f x.png            copy x.png as image data to clipboard
-```
-
-If `-copy` is used, the command will exit when the data is no longer
-available from the clipboard. You can always send the command to the
-background using a shell `&` operator, for example:
-
-```bash
-$ cat x.txt | gclip -copy &
-```
