Simple repl for gulp compatible with gulp#3.x and the future gulp#4.x.

// gulpfile example
var gulp = require('gulp');
var repl = require('gulp-repl');

gulp.task('repl-start', function (cb) {
  gulp.repl = repl(gulp);
});

gulp.task('repl-stop', function (cb) {
  if (gulp.repl) {
    gulp.repl.close(); // same as nodejs.org/api/readline.html#readline_rl_close
  }
	cb();
});


gulp.task('foo', function (cb) {
  // do foo stuff
  cb();
});

gulp.task('bar', function (cb) {
  // do bar stuff
  cb();
});

gulp.task('default');

Then, on your terminal write:

gulp repl-start

and you'll have a repl with:

1. Press Enter to see the prompt
2. write the tasks you want to run
3. Press Tab for completion

$ gulp
... some task logging here
(press Enter)
> (press Tab to see completion)
foo      bar      default
> foo bar
[10:39:11] Starting 'foo'...
[10:39:11] Finished 'foo' after 13 μs
[10:39:11] Starting 'bar'...
[10:39:11] Finished 'bar' after 5.52 μs

The module exports a function

var repl = require('gulp-repl');

Calling the function with gulp creates a readline instance using gulp tasks as commands for a REPL.

var gulp = require('gulp');
var gulpREPL = require('repl');

// to start the repl
gulp.repl = gulpREPL.start(gulp);

function add(Gulp gulp)

Adds the given gulp instance for the REPL to be able to lookup and returns the module again.

function remove(Gulp gulp)

Removes the given gulp instance for the REPL to be able to lookup and returns the module again.

function reset()

Removes all of the previously added instances and returns the module again.

function get(Gulp gulp)

Takes a gulp instance as argument

returns

• null if the gulp instance wasn't stored yet
• all of the stored instances if no arguments are given
• metadata stored for the given gulp instance if was already stored

function start(Gulp gulp)

Starts a REPL listening on stdin and writing on stdout and returns a readline.Interface instance. Each of the commands typed to the REPL are looked up in each of the instances given on add.

See node's core module readline documentation about the readline.Interface.
