bc

A better basic calculator. Like the original bc, but with a better prompt. Work in progress. Very incapable right now.

What?

The idea behind bc is to display partial results to the right of the cursor in yellow while we type. A little example can be found in the video above. Minor syntactic cleanups have been developed as well (e.g. no local keyword). We have infinite precision integers and 90 decimal mantissa precision floats.

TODO

• A good readline copy (haskeline is sadly out of the question for this project)
• Comment parsing
• Closures that can modify the parent environment (but do away with the local keyword).
• Better arbitrary precision floats
