A minimal compiler written in ruby

compiler-rb

A (very, very) basic compiler written in ruby. It compiles code written in a toy language to javascript.

It should probably be called a "transpiler" 🤭

compiler.rb        # The compiler
example            # The toy language
README.md          # Well... Read it!!!

Prerequisite

You need both a ruby and node interpreter for this to work 🙃

• Ruby
• Node

Run the code

ruby compiler.rb | node
# 3 -> what you should get/see :-)

Feel free to change the literal arguments to f on Line #5.

Example:

TEST = 'console.log(f(4, 22));'

This work is based on the excellent A Compiler From Scratch screencast by Gary Bernhardt.
