How can I run a task in Grunt using an array of filenames which are dynamically generated?

问题

I am fairly new to using Grunt but have a fairly good understanding of how tasks are installed and run. So far I am able to run everything as I want which includes minifying js, copying files and running jshint.

I now want to run 'clean' to remove files from a folder but only an array of selected files which I hope to generate dynamically.

So if I had a dynamically generated array e.g.

var deleteFilenames = ["file3.js","file2.jpg","file7.html"] etc.

How would I set a grunt clean task to just delete these files?

Any help much appreciated.

回答1:

You can use a variable to construct the config passed initConfig:

var deleteFilenames = ["foo", "bar", "baz"];
grunt.initConfig({
    clean: deleteFilenames
});

In the code above, the list is static but deleteFilenames could be constructed from an algorithm that computes file names.

You can try using a wildcard token:

clean: ["file*"]

If you want something cleaner, you should include your Gruntfile.js or try to ouput your generated assets into a specific directory (such as dist/).
