A simple Lisp-like language that I'm implementing in Go.
Writing a Lisp is something I'd always wanted to do and I wanted to use Go in a project that was slightly bigger than a programming puzzle.
So far the following functionality is there:
- CONS
- CAR
- CDR
- QUOTE
- LAMBDA
- SETQ
- ATOM
- EQ
- COND
- PROGN
- LET
+,-,*,/- Infinite precision math (Integers and ratios)
- DELETE (to remove an existing symbol from the environment)
- STORE (to write all symbols from the current environment to a text file)
- LOAD (to load symbols into the current environment from a text file)
Debugging statements can be turned on and off with (**DEBUG** T) and (**DEBUG** NIL)
It's a LISP-1 (single namespace for both values and functions). The scoping is static.
Other features that I intend to add (in likely order):
- Macros
- CSP functionality (Goroutines, Channels, Select)
- Strings
- Tail Call optimization
- Maps, Sets
- Structs
- Invoke Go functions
As a stretch goal, I'd like to add the ability to generate compiled code as well.
At some point, I'm going to start renaming the special forms and switching to lower case (LAMBDA -> fn, for example).
