reedline-repl-rs

Library to help you create a fancy REPL for your application based on nushell's reedline.

Features: - Popular clap crate Command used as configuration interface - General editing functionality, that should feel familiar coming from other shells (e.g. bash, fish, zsh). - Interactive tab-completion with graphical selection menu - Fish-style history autosuggestion hints - History with interactive search options (optionally persists to file, can support multiple sessions accessing the same file) - Configurable keybindings (default emacs-style bindings). - Configurable prompt with hooks to update after commands run - Command Syntax highlighting - Feature-flag for async support - Tip: Search history with CTRL+R, clear input with CTRL+C, exit repl with CTRL+D

Basic example code:

```rust use reedlinereplrs::clap::{Arg, ArgMatches, Command}; use reedlinereplrs::{Repl, Result};

/// Write "Hello" with given name fn hello(args: ArgMatches, context: &mut T) -> Result> { Ok(Some(format!("Hello, {}", args.valueof("who").unwrap()))) }

fn main() -> Result<()> { let mut repl = Repl::new(()) .withname("MyApp") .withversion("v0.1.0") .withdescription("My very cool app") .withbanner("Welcome to MyApp") .with_command( Command::new("hello") .arg(Arg::new("who").required(true)) .about("Greetings!"), hello ); repl.run() } ```

Running the example above:

```plain Welcome to MyApp MyApp〉help MyApp v0.1.0: My very cool app

COMMANDS: hello Greetings! help Print this message or the help of the given subcommand(s)

MyApp〉help hello hello Greetings!

USAGE: hello

ARGS:

OPTIONS: -h, --help Print help information MyApp〉hello Friend Hello, Friend MyApp〉 ```

Thanks

Forked from repl-rs by Jacklund, changed to use reedline which is an advanced readline clone and the base of nushell.
