[IPython-dev] Notebook codemirror support for language not distributed with codemirror?

[Tom Quarendon]

OK, so I can't get this to work reliably.

It's a timing thing. The way I've implemented it is simply to do
		onload: function() {
			require('kernelspecs/mykernel/mymode');	
		}
In my kernel.js

However, the success of that depends on the asynchronous timing of that being executed verses the call to set_codemirror_mode here (notebook.js):
	this.events.on('kernel_ready.Kernel', function(event, data) {
		...
	            that.set_codemirror_mode(cm_mode);
	        });

So I suspect I need to do something more sophisticated. Bearing in mind my lack of knowledge of require etc (i.e spell it out please!), can anyone suggest anything? Cal I explicitly call set_codemirror_mode myself somehow (I don't know how I'd get hold of a suitable object to call the method on though)?

Thanks.

You can drop a kernel.js next to your kernel.json  at installation time, it should  describe an AMD module that define a `unload` method that will be called when you switch to you r kernel. 

The can manually load/register a code mirror mode in the notebook.
