Question

I’ve got a bunch of .coffee files that I need to join into one file.

I have folders set up like a rails app:

/src/controller/log_controller.coffee
/src/model/log.coffee
/src/views/logs/new.coffee

Coffeescript has a command that lets you join multiple coffeescripts into one file, but it only seems to work with one directory. For example this works fine:

coffee --output app/controllers.js --join --compile src/controllers/*.coffee

But I need to be able to include a bunch of subdirectories kind of like this non-working command:

coffee --output app/all.js --join --compile src/*/*.coffee

Is there a way to do this? Is there a UNIXy way to pass in a list of all the files in the subdirectories?

I’m using terminal in OSX.

They all have to be joined in one file because otherwise each separate file gets compiled & wrapped with this:

(function() { }).call(this);

Which breaks the scope of some function calls.

You could write a shell script or Rake task to combine them together first, then compile. Something like:

find . -type f -name '*.coffee' -print0 | xargs -0 cat > output.coffee

Then compile output.coffee

Adjust the paths to your needs. Also make sure that the output.coffee file is not in the same path you’re searching with find or you will get into an infinite loop.
