readline
========
[](https://godoc.org/github.com/ergochat/readline)
This is a pure Go implementation of functionality comparable to [GNU Readline](https://en.wikipedia.org/wiki/GNU_Readline), i.e. line editing and command history for simple TUI programs.
It is a fork of [chzyer/readline](https://github.com/chzyer/readline).
* Relative to the upstream repository, it is actively maintained and has numerous bug fixes
- See our [changelog](docs/CHANGELOG.md) for details on fixes and improvements
- See our [migration guide](docs/MIGRATING.md) for advice on how to migrate from upstream
* Relative to [x/term](https://pkg.go.dev/golang.org/x/term), it has more features (e.g. tab-completion)
* In use by multiple projects: [gopass](https://github.com/gopasspw/gopass), [fq](https://github.com/wader/fq), and [ircdog](https://github.com/ergochat/ircdog)
```go
package main
import (
"fmt"
"log"
"github.com/ergochat/readline"
)
func main() {
// see readline.NewFromConfig for advanced options:
rl, err := readline.New("> ")
if err != nil {
log.Fatal(err)
}
defer rl.Close()
log.SetOutput(rl.Stderr()) // redraw the prompt correctly after log output
for {
line, err := rl.ReadLine()
// `err` is either nil, io.EOF, readline.ErrInterrupt, or an unexpected
// condition in stdin:
if err != nil {
return
}
// `line` is returned without the terminating \n or CRLF:
fmt.Fprintf(rl, "you wrote: %s\n", line)
}
}
```
