Allow multiple patterns

[rubennorte]

Right now we can only use a single pattern to detect unused files:

new UnusedFilesWebpackPlugin({
  pattern: 'js/src/**'
})

It would be nice if we could set an array of patterns. That way we could check if all files in src and certain files in the test directory, for example, are used or not:

new UnusedFilesWebpackPlugin({
  patterns: [
    'js/src/**',
    'js/test/support/**',
    'js/test/specs/**'
})

I think it would be as easy as replace glob with multi-glob

Good idea!

Agreed it would be much easier, but if you're stuck with this you can still do it with the current syntax:

In my solution I've done this:

new UnusedFilesWebpackPlugin({
    pattern: '+(lib|assets)/**/*.*'
}),

See syntax here: https://github.com/isaacs/node-glob#glob-primer

Any suggested libraries for multiple glob patterns?

@tomchentw glob-all - https://www.npmjs.com/package/glob-all

In a similar plugin I wrote, I was able to use glob-all as a drop-in replacement for glob. I think it also accepts both strings and arrays. You could try it and see if it passes your current tests.

@QWp6t thanks! This looks interesting
