Compiling with gsc into standalone interpreter about cs61a HOT 1 CLOSED

Hello @alexshendi !

Thanks for experimenting with this old project! As stated, it was a former programming project issued at UCB. This repository contains my solution to that programming project. Gambit scheme came into the picture only because of the need for a scheme interpreter which runs in the browser. Fortunately, Marc Feeley has created one.

I don't know what your intention is, but you can use the official Berkeley Logo standalone executable, if you want to play with the Berkeley Logo dialect. This project was not meant to produce an efficient, production Logo interpreter. The goal was to learn how to write a Logo interpreter in a language which has a lot in common with Logo itself.

Some comments to your changes.

• The exit-logo is a continuation, which essentially drops you back to the place, from where you've called the driver-loop procedure. It is not meant to exit the scheme interpreter completely.
• The logo-load procedure deals with reading from files, including the eof-object?-check. The line-obj class is not meant to do that. It is meant to hold the "line" for parsing.
• The maybe-num procedure is called indirectly and is used by the arithmetic primitives.
• The rest you've changed like macro-definitions and some procedures are with the supplied code by UCB for the project.
