Using Grunt-uncss with WordPress

[brianjking]

Hi,

I'd love to use this on several WordPress sites, however, the site linked in your Readme for the tutorial & gruntfile is not working.

Any help/tips/suggestions/guidance would be highly appreciated! Thanks!

I have used UnCSS in several Wordpress builds using version 0.4.3 without any issues, works great in fact. However, with 0.4.4 I get the error, 'Warning: Destination (wp-content/themes/rjrstudios/dist/css/rjr_theme.clean.css) not written because src files were empty. Use --force to continue.' The configuration which is the same as previous builds apart from the file dirs is below.

I used this workflow as a base, https://gladdy.uk/blog/2014/04/13/using-uncss-and-grunt-uncss-with-wordpress/, developing within a local MAMP environment.

The UnCSS config in the Gruntfile.js is as follows:

uncss: {
    dist: {
        options: {
            ignore : ['.hidden-xs'],
            stylesheets : ['wp-content/themes/rjrstudios/src/css/bootstrap.css', 'wp-content/themes/rjrstudios/src/css/rjr_theme.css'],
            ignoreSheets : [/fonts.googleapis/],
            urls : [],
        },
        files: {
            'wp-content/themes/rjrstudios/dist/css/rjr_theme.clean.css': ['http://localhost/RJRStudios/']
        }
    }
},

The 'urls' value gets overwritten by load_sitemap_and_uncss task.

If anyone makes this to work again, please make a PR with the doc changes to add in our README.md.

Is there anybody who solved the problem "'Warning: Destination (file path) not written because src files were empty. Use --force to continue.' ? I need a help. Thank you.
