About CoffeeScript support in Nodeclipse
While most Node.js developers ask Why?, there is certain percentage of developers that do use CoffeeScript every day. CoffeeScript is also #6 package in Most Depended-upon Packages list on https://npmjs.org . And some our friends use it.
coffeescript-eclipse is using XText, an Eclipse project aimed for helping creating new languages. Currently Robert Gründler has expressed desire to become the owner of the project. So we are slowly working on CoffeeScript support in Eclipse.
If you want to try old 0.2.2.201203211152 version, you can install it with required XText in one step using CoffeeScript Editor quick installer.
