That's a crappy compiler of a crappy language. Mail-lang is an esoteric programming language whose control flow is defined by emails:
- you want to set a variable? Email it the value.
- You want to call a function? Email it the arguments.
- You want to read the result of the function? Reply to the sent email.
This README is also crappy. I got this idea a long time ago and I'm only uploading it for giggles.
You can find in examples/fibonacci.mail a program that computes the fibonacci number of the user's stdin input.
Interesting domains to lookout for are: ...@local, ...@global, ...@arguments, and ...@continuations
python compiler.py examples/fibonacci.mail && ./fibonacci
Oh you need a /tmp folder, the intermediary C code is written there;
/tmp/maillang-compiled-program.c
