Coffee-errors NPM

coffee-errors

Patches error stack to display correct line numbers. CoffeeScript has built in support for this, but it only works when the script is executed through the coffee command. If you are running mocha, node-dev, jasmine or any other method, the functionality isn't on.

This is a pretty much straight copy of the original source, except it doesn't compile the source maps until necessary therefore speeding up the initial bootup process.

The package reuses expects you to have coffee-script already installed in your project.

Support

Please help me spend more time developing and maintaining awesome modules like this by donating!

The absolute best thing to do is to sign up with Gittip if you haven't already and donate just $1 a week. That is roughly a cup of coffee per month. Also, please do donate to many other amazing open source projects!

Installation

npm install coffee-errors

Using

To get this to work, you just need to require the module once per run-time, like so.

require 'coffee-errors'

Results

Whenever an error is thrown, all stack lines in .coffee files will be fixed to show correct line number. YES!
