Fortio's terminal is a readline style library. It handles prompts, edit (like Ctrl-A for beginning of line etc...), navigating through history using arrow keys, loading and saving history from file, etc... It works on everywhere go does (including macOS, Windows (using Terminal app), Linux).
See example/main.go for a rather complete example/demo.
See the godoc above for details.
The grol command line repl and others use this.
The implementations currently is a wrapper fully encapsulating (our fork of) x/term, i.e. fortio.org/term and new features like the interrupts handling (filters Ctrl-C ahead of term' reads)
