Autocompletion for gulp about gulp HOT 11 CLOSED

If somebody wants to make the autocomplete files (these https://github.com/gruntjs/grunt-cli/tree/master/completion) for gulp I would be open to accepting a PR

from gulp.

This will need more investigation, than I thought at first. Gulp cli do not lists tasks in "--help", so way that grunt does autocompletion (greps help output) is not suitable. But it can be done, if we manage write this autocompletion script in node - if this is possible, then all that we need is require gulpfile.js and list its this.tasks.

P.s. May be it's possible to fetch tasks from one-liner: node -e "console.log(require('{$GULPFILE}').tasks.join(' '))"

from gulp.

@floatdrop That seems like the easiest solution

from gulp.

this.tasks is an object of more than just names. It seems like orchestrator could benefit from a .taskNames() that harvested that list though.

from gulp.

@robrich node -e "console.log(Object.keys(require('{$GULPFILE}').tasks).join(' '))" will probably be good enough. No need to add more API surface to support edge cases

from gulp.

Too bad, that gulpfile.js do not exposes nothing (since there is no exports in it).

from gulp.

@floatdrop what would it export?

from gulp.

@sindresorhus gulp instance would be enough - after you get it, you can access his .task property and extract tasks names from it.

from gulp.

@floatdrop somewhat hacky, but something like this should do it:

var gulp = require('require-modify')('./gulpfile', function (src) {
    return src + ';module.exports = gulp;';
});

the beginning ; is in case the user have forgotten a semicolon on the last statement

https://github.com/sindresorhus/require-modify

from gulp.

Because the gulp object is a singleton, couldn't you do this as well?

var gulp = require('gulp');
require('./gulpfile');
console.log(Object.keys(gulp.tasks).join(' '));

from gulp.

@timrwood cool! This will do the trick node -e "var gulp = require('gulp'); require('./gulpfile'); console.log(Object.keys(gulp.tasks).join(' '));"

from gulp.
