The 30 Minute Compiler
This is the source code from the IndyJS April 2014 meetup.
basic.js expects source code on stdin and outputs generated JavaScript to stdout.
Use shell redirection to perform an actual compilation:
node basic.js < test.bas > test.js && node test.js
Uncomment one of the jsonify lines in basic.js to watch the tokens from the lexer, and statements from the parser, respectively.
