Lake Scheme

A quick and dirty scheme written in C, for fun and to use while reading The Little Schemer. Very quick and dirty, a weekend hack.

Compiling & Running

Portable ANSI C, no deps, nothing to configure, no documentation!

$ make
$ ./lake

That will drop you at a repl. You can type expressions and they will be echoed back to you. There are symbols, integers, strings, and lists.

> (foo bar 42 "hello" (nested list))
(foo bar 42 "hello" (nested list))

Hooray! It parses (reads), evaluates, and then prints things back.

Lake needs:

• booleans
• chars
• functions
• flesh out eval, write apply
• dotted lists
• primitives (especially define)
  • define and friends
  • branching
  • native type operations
    • symbol
    • integer (math)
    • boolean (logic)
    • char
    • string
    • function
    • list (cons, car, cdr, ...)
    • dotted list
• a minimal stdlib
• sugar such as '... -> (quote ...)

I don't think I'll need any other numeric types, but they are easy to implement anyway when performance is no concern and they're all boxed.
