A silent mode

[Mehdy Dara]

Hi,

I would mute output with option --silent but gulp-size continue to print log.

$ gulp build --silent
[12:43:13] all files 4.29 kB
[12:43:13] all files 3.06 kB
[12:43:13] all files 1.94 kB
[12:43:14] all files 60.22 kB

gulp doesn't support advanced logging. I would be happy to use appropriate logging methods when available, but I'm not interested in adding custom logic for every plugin just to support this right now.
