Hi - I have moved to Atom and processing with live preview, so far so good.
In the processing ide I made a sketch called test1.pde, then I created a class Bubble.class then I opened in Atom.
It seems live preview only works with the main file, so I will need to copy all my classes into the main file for live preview to work correct?
also is there any way to view the output when i print(pop); ?
Thx in advance -

For [JRubyArt](https://ruby-processing.github.io/JRubyArt/), I created a [atom package](https://github.com/ruby-processing/atom-k9) that allows me run sketches from atom, it has a custom console that displays console output. This should be possible with live preview (but I haven’t tried it). With ruby processing all code is in regular ruby files, so you can put classes in separate files if you wish.
