SBT: How to define an includeFilter that includes all files in a certain path?

I'm trying to figure out how to write an input filter that matches any file with a particular extension in a specified sub-directory. I cannot seem to get it to work.

More specifically, I want to include modules/*.styl

I'm having a heck of a time getting that pattern to work in my build.sbt file I'm trying to do something like this:

includeFilter in (Assets, StylusKeys.stylus) :=  "modules" * "*.styl"

I haven't ben able to come up with anything that even will allow SBT to start up. Anyone have a clue?

I'm using SBT 0.13.5.

First the includeFilter key has type FileFilter. Look this link to see how it is defined.

I think there is no easy way to do what you want since implicits from String to FileFilter produce only NameFilter. Those only test the file name, not the path as you want to.

You can define your own FileFilter based on the examples provided. The idea: you create one filter for the parent directory and then combine it with a PatternFilter for the file name.

includeFilter in (Assets, StylusKeys.stylus) := new SimpleFileFilter(file => file.getParent == "modules") && "*.styl"

Of course you will perhaps have to modify the function passed to SimpleFileFilter according to your needs.
