Hi again,
Julia programmes not yet can be compiled in the sense that c and fortran can be compiled. You define your methods/functions and later you use them in real context. As your julia file executed from top to down, the main julia executable parses it to internal codes and as you call a function within the file julia converts it to machine code and runs it similar to python but JITed.
I don't know what you mean by synchronize but you can run a part of code where cursor is in your file by just shift+enter.
I think you may better start with generic distribution at
julilang.org/download to get feel how julia compilation works. Also, if you don't have a reason to use discontinued or deprecated lighttable IDE interface you'd better start with Atom IDE interface and instructions for it is here
