When Atom was first launched I mentioned that it might make sense to port the interesting parts of LT over to it since the core editor isn't what's important (and it's also a ton of work to get right). LT has found its way into lots of projects, from the Chrome Dev Tools to XCode and IntelliJ, which is a tremendous honor for us - it's great to see it coming to Atom as well.
I've been thinking a lot about what makes for a good development experience, and how to properly "factorize" an IDE to provide a consistent experience across different languages. The monolithic IDE experience can be great (once you get it set up) if all your work is in a single language. But for people like me, having a confusingly different development environment for each project is a nightmare.
This is a tiny step toward the dream of having a consistent core editor but with powerful tools for each language that allow introspection into the state of the running machine.
Atom has been improving really fast - it's my editor of choice now.
It would be great if this could recognise some common image formats in memory (cairo surfaces, PIL) and visualise those on mouseover.
Possibly similar for arrays - be able to visualise it as a wave or even playback as audio.
Is there any chance of factoring out the support for the popouts? - It would be great if this could appear in other editors.
There's a (nascent) project called `jmp` (for Jupyter Messaging Protocol) that implements kernel communication in JS: https://github.com/n-riesco/jmp. I'll probably contribute to that and factor out my kernel communication.
