Processing multiple files with a wildcard.

[w-jbarlow]

New feature request. I would like to be able to specify source as a wildcard, and destination as a directory. I have many html files (and JS files and CSS files) that I need to process for several environments over and over. Currently it appears that you can only specify a single file per line or per preprocess task. Unless I am mistaken, it seems that only inline will let you do wildcard preprocessing.

preprocess: {
html: {
src: './src/*/.html',
dest: './processed'
}
}

+1 That would be very handy

You can dynamically build the files array with grunt to support this, and it doesn't need to be done per-task

That worked perfectly for me. Thanks @jsoverson for the pointer.

For anyone else wanting to see an example using grunt-preprocess:

preprocess : {

    options : {

        context : {

            title : '<%= pkg.title %>',
            description : '<%= pkg.description %>',
            name : '<%= pkg.name %>',
            version : '<%= pkg.version %>',
            homepage : '<%= pkg.homepage %>',

        },

    },

    dev : {

        /*
        files : {

        }
        */

        files: [

            {

                expand: true,
                cwd: './files/templates/',
                src: ['**/*.html'],

        ],

    },
