+# CancelReader
+
+[](https://github.com/muesli/cancelreader/releases)
+[](https://pkg.go.dev/github.com/muesli/cancelreader)
+[](/LICENSE)
+[](https://github.com/muesli/cancelreader/actions)

+
+A cancelable reader for Go
+
+This package is based on the fantastic work of [Erik Geiser](https://github.com/erikgeiser)
+in Charm's [Bubble Tea](https://github.com/charmbracelet/bubbletea) framework.
+
+## Usage
+
+`NewReader` returns a reader with a `Cancel` function. If the input reader is a
+`File`, the cancel function can be used to interrupt a blocking `Read` call.
+In this case, the cancel function returns true if the call was canceled
+successfully. If the input reader is not a `File`, the cancel function does
+nothing and always returns false.
+
+```go
+r, err := cancelreader.NewReader(file)
+if err != nil {
+ // handle error
+ ...
+}
+
+// cancel after five seconds
+go func() {
+ time.Sleep(5 * time.Second)
+ r.Cancel()
+}()
+
+// keep reading
+for {
+ var buf [1024]byte
+ _, err := r.Read(buf[:])
+
+ if errors.Is(err, cancelreader.ErrCanceled) {
+ fmt.Println("canceled!")
+ break
+ }
+ if err != nil {
+ // handle other errors
+ ...
+ }
+
+ // handle data
+ ...
+}
+```
+
+## Implementations
+
+- The Linux implementation is based on the epoll mechanism
+- The BSD and macOS implementation is based on the kqueue mechanism
+- The generic Unix implementation is based on the posix select syscall
+
+## Caution
+
+The Windows implementation is based on WaitForMultipleObject with overlapping
+reads from CONIN$. At this point it only supports canceling reads from
+`os.Stdin`.
