https://github.com/nushell/reedline/ deno ffi wrapper

Usage

This library requires --unstable flag

import { ReedLine } from "https://deno.land/x/reedline_deno@0.17.1/src/mod.ts";

const rl = await ReedLine.create();

while (true) {
  const line = await rl.readLine({
    render_prompt_left: "> ",
    render_prompt_right: "<",
  });
  if (line.signal === "CtrlC") {
    console.log("CtrlC");
    break;
  }
  if (line.signal === "CtrlD") {
    console.log("CtrlD");
    break;
  }
  console.log(line.value);
}

console.log("Now extra showcase:");

import {} from "https://deno.land/x/reedline_deno@0.17.1/src/extra.ts";

const answer = await rl.question("What's up?", {
  render_prompt_left: "??> ",
  render_prompt_right: "<#",
});
console.log("You are: ", answer.value);

Development

workflow:

deno task example should be used to test changes.
If CARGO_TARGET_DIR is not already set you need to run with CARGO_TARGET_DIR=$PWD/target deno task example

design:

Try to mimic https://docs.rs/reedline/latest/reedline api as best as typescript allows.
Apis that don’t exist in reedline should go to src/extra.ts. (for example ReedLine.question)
