Creating a REPL

[Mike Austin]

My language is working great, so now I'd like to write a simple REPL. A REPL is a little different in that it usually reads one statement at a time. It also handles multiple lines differently when inputting functions for example. I've got a few questions:

Should I break down rules into REPLable chunks? Should I use a separate grammar file? Also, only peg$parse is exported. How should I call peg$parseSourceElement() for example?

Thanks!
Mile

Hi, Mike. Take a look at the allowedStartRules option of PegJS' generate function, that might help you keep the REPL and the module grammar the same.

Atenciosamente / Sincerely,
