This week I came across one that I feel is worth a special mention: EmberScript, an extension of CoffeeScript created by Gordon Hempton, who blogs regularly about Ember.js.
I've been floating the idea of writing a book teaching Ember.js in CoffeeScript on the same interactive platform as my Backbone + CoffeeScript book. But it hadn't occurred to me to extend CoffeeScript for a better fit with Ember.js. I wrote Gordon to ask how he got the idea, and this was his reply:
You can read more about how Gordon modified the CoffeeScript Redux compiler in his blog post.
Is this the first time a programming language has been forked to support the features of an application framework? Like everything else, I suspect it's been done before. Please leave a comment if you have an example.
