At the moment the coffee-script node.js module lacks proper support for stack-traces when compile coffeescript files. This module adds the correct line and column indication in stack-traces for coffee-script modules loaded with require() or parsed using the coffeem command (which replaces coffee command).
to install :
npm install coffee-script-mapped
to run as a command line you can call
coffeem (which works exactly as the coffee command, except it'll have proper stacktraces)
--no-source-mapsto the node or coffeem commands to disable this module (which will revert to the standard coffee-script module)
