Debugging CoffeeScript line-by-line

Question

Is there a way to debug CoffeeScript line-by-line?

I understand that it compiles into Javascript. But this sounds like it could make it a pain to debug.

Answer 1

Update: there's currently a redesign of coffeescript compiler that generates source maps, which should enable you to debug your coffeescript in most recent versions of Google Chrome (18 and upwards I think).

I think it's not production-ready yet, but it's worth mentioning.

Answer 2

if you are running coffeescript from the terminal you can debug it line-for-line using node-inspector, launching your script this way:

coffee --nodejs --debug-brk yourscript.coffee
