It seems like it would be a matter of writing a little server type application that would communicate via stdin/stdout. I assume one could then send messages to the code that evaluates methods/function definitions and provide result feedback via stdout. Maybe it could also understand some commands like doit and accept. It could be interesting to have a TCP based interface as well. How difficult would it be to do something like this? I may start looking into this. It seems like a good project to jump into the deep end, start paddling, and drinking a little water (hopefully not too much). Is the code that handles this kind of thing readily accessible? I've started looking around a bit.

The answer is that it is basically trivial to do and many people have 
already done it in various forms - I even did a TCP server for Joe 
Armstrong (one of the creators of Erlang) that does similar things:


...BUT... when it comes to Joe he wanted to use Squeak from Erlang in 
order to dynamically create UIs etc. So he had a reasonable use case. ;)

...if you just happe to "like REPLs" then you should really try to use 
and learn the Squeak/Pharo IDE. Think of it as a full blown live graphic 
REPL with tons of cool tools. Every text area in Pharo/Squeak is a 
"REPL" anyway.
