Ok, you'll have to run it through the compiler first with the -m option:

test.coffee:

  require 'source-map-support'
  throw new Error("Test")

Now do:

  npm install source-map-support
  coffee -c -m test.coffee
  node test.js

This gets you the correct line numbers.

The hard part for me to understand is that I've got way more than just a single file. I've got hundreds of coffee script files for a rather complex nodejs/express app.

I start it up with something like this:

  nodemon -w . lib/start/web.coffee

  or in production:

  coffee lib/start/web.coffee

That web.coffee file then require's a chain of files.

If I try to compile the source maps for all of my files first, using something like this:

  mkdir .compile
  coffee -m --output .compile --compile ./

In the .compile folder, there is a few oddly named subdirectories (d, b, rands, sc) with the compiled .js files in there and the respective .map files. This seems to totally break my require chain.

Since I don't normally pre-compile all my coffee script files, I just run them directly using nodemon or coffee, how can I work the maps into my dev process?
