Running it simply with hsandbox go will split your terminal screen (with … Read more
There is still nothing built-in to provide the exact functionality you describe. However, an alternative to using require it to use the .load command within the REPL, like such: .load foo.js It loads the file in line by line just as if you had typed it in the REPL.

IPython is extremely useful if you like using interactive sessions. For example for your use-case there is the %save magic command, you just input %save my_useful_session 10-20 23 to save input lines 10 to 20 and 23 to my_useful_session.py (to help with this, every line is prefixed by its number). Furthermore, the documentation states: This … Read more
