Great work, well done! Pascal was the second language I learned, after Basic. I'm interested in studying the code and possibly replicating it for the purpose of learning about how compilers work. Could you give a general overview of the components, or steps you took to implement them? Thanks! |

It's a two-pass compiler. The first pass runs the code through the Stream, Lexer, and Parser classes to generate a parse tree (with type information). The second pass generates bytecode using the Compiler class. The compiled bytecode is then handed to Machine to execute. Start in IDE.js in the _run() function. Also go into turbo.css and comment out the "display:none" line in the .debug-output block. That'll let you see the parse tree and generated bytecode.
