Adding another directory to joinTo in config fails

In config I’m looking to add another JavaScript file to the joinTo object:

      joinTo:
        'javascripts/bookmarklet.js': /^bookmarklet/
        'javascripts/app.js': /^app/
        'javascripts/vendor.js': /^vendor/

This does not error but no file is produced. My source file and directory structure are correct?

because brunch watches only app, vendor, test (which is configurable) and not the whole project directory, because user might have server files there that should not be compiled and all other stuff

      joinTo:
        'javascripts/bookmarklet.js': /^app\/bookmarklet/
        'javascripts/app.js': /^app\/(?!bookmarklet)/
        'javascripts/vendor.js': /^vendor/

this would work
