Exclude file in Brunch regular expression

Question

I want to exclude a file mapdata.coffee inside the view folder in joinTo config of Brunch.

What I tried is

'javascripts/app.js':/^app(\/|\\)(?!(tests|store-test|views\/mapdata.coffee))/

Where am I missing?

Seems like it should work, unless you're on a Windows system using backslashes as the path separator. In which case

/^app[\\\/](?!(tests|store-test|views[\\\/]mapdata.coffee))/

ought to work.

In a node REPL:

> /^app(\/|\\)(?!(tests|store-test|views\/mapdata.coffee))/.test('app/views/mapdata.coffee')
false
> /^app(\/|\\)(?!(tests|store-test|views\/mapdata.coffee))/.test('app\\views\\mapdata.coffee')
true
> /^app[\\\/](?!(tests|store-test|views[\\\/]mapdata.coffee))/.test('app\\views\\mapdata.coffee')
false
> /^app[\\\/](?!(tests|store-test|views[\\\/]mapdata.coffee))/.test('app\\views\\foo.coffee')
true

You can also define your joinTo s with things other than regexes. Take a look at the anymatch documentation .
