Respect gulp --silent?

Hi, would it be possible to have the default quiet option based on the --silent flag of gulp’s cli?

According to this comment the setting can be found by doing:

const argv = require('minimist')(process.argv.slice(2));
const isSilent = !!argv.silent;

then the change could be as simple as replacing

opt.quiet = bool(opt, 'quiet', false);

by

opt.quiet = bool(opt, 'quiet', isSilent);

If that sounds reasonable I’ll add some tests, try it out and submit a pull request when I have time.

Sorry I forgot to “try it out on Monday” for so long!

It doesn’t seem to automatically be silent if --silent is passed to the top level gulp, but passing quiet: true in the options for the call to inject does silence it (gulp-inject 4.1.0, gulp 3.9.0).

This pull request would suggest that the functionality is already there, but neither calling gulp with --silent nor setting "options.quiet": true disabled the output from gulp-inject for me.

I am using gulp-inject 4.2.0 and gulp 3.9.1
