caprice is a work in progress REPL for Rust projects featuring an easy to use, zsh like autocomplete feature.

using caprice with the spinning square example from Piston

Usage

• typing #list will print all available tokens in the caprice console in alphabetical order
• pressing tab will cycle between all autocompleted suggestions

caprice uses crossterm as its terminal emulator.

Example:

```rust use caprice::{Caprice, CapriceCommand}; use std::thread; use std::time::Duration; fn main() { let mut caprice = Caprice::new() .setprompt("!:") // set the prompt .disablectrlc() // pressing control + c won't close the caprice console .init(); // initialises the caprice terminal // set some tokens caprice.setkeywords(&[ "sometoken".toowned(), "someothertoken".toowned(), "exit".toowned(), // an exit keyword ]); // caprice.run() will run the caprice in a separate thread. // you can use the returned tx and rx channels for receiving and sending messages // to caprice instance let (tx, rx, capricehandle) = caprice.run().unwrap(); // our main application runs here // for this example we will simply print back // the tokens send by caprice loop { // if we received a token from caprice if let Ok(token) = rx.tryrecv() { match token.asstr() { // leave if the user types exit "exit" => { tx.send(CapriceCommand::Println("bye".toowned())).unwrap(); tx.send(CapriceCommand::Exit).unwrap(); capricehandle.join().expect("couldn't join thread").expect("Caprice run has encountered an error"); break; // at this point caprice has already exited, let the main process do as well }, // else send back the token to be printed _ => { let printtoken = format!("Got {} from Caprice", token); tx.send(CapriceCommand::Println(printtoken)).unwrap(); } } } // let the thread sleep for some time thread::sleep(Duration::frommillis(10)); } }

```

Windows terminals

Currently caprice is buggy on all windows terminals
