makes debugging coffee-script easier by displaying corresponding lines of code in the stack-trace with style

Coffee-Trace makes debugging coffeescript code easier by attempting to point corresponding coffeescript code and line numbers and styling the stacktrace a little bit.

Running this..

require('coffee-trace')

test = ->
  people =
    john:
      first_name: 'john'
      last_name: 'doe'
    mary:
      first_name: 'mary'
      last_name: 'jane'

  console.log("Welcome", people[p].first_name, people[p].last_name, "!!!") for p in ['john', 'mary', 'josh']

process.nextTick test

will result in this:

If you love Coffee-Script and Node.js, you will provably also be frustrated by the challenges of quickly finding and debugging the coffeescript line corresponding to the one pointed out by the stack-trace.

I've been searching a cleaner solution myself, and have found some very useful links and discussions, but am yet unsatisfied. So, while SourceMaps implementation in Coffee-Script is a reality, this is the least I can do.

Become a masochist by enjoying uncaughtExceptions and crashes. Just by installing with:

npm install coffee-trace

and at the very beginning of your code:

require('coffee-trace')

• Testing ( make something crash the way expected )
• Beautify and comment code
