* iota

Iota is a lisp interpreter.  It is very much a work in progress.

build:

#+begin_src sh

make

#+end_src

run:

#+begin_src sh

./iota

#+end_src

** What it has

   + Interpretation.

   + Lisp-1 namespacing.

   + Lexical binding.

   + Common Lisp-style macros.

   + Self-evaluating keywords.

   + Some arg parsing.

   + Some introspection.

   + Decent I/O.

** What it doesn't have

   + Booleans (nil serves as false)

   + Garbage collection.

** What I want it to have

   + Self-hosted compilation, maybe to some kind of iota bytecode, maybe to javascript, maybe to C, maybe to all three.

   + Much more introspection.

   + Better arg parsing.

   + More (fast) fundamental data structures, like maps/hashtables/dictionaries and resizable vectors.

   + Garbage collection.

** Acknowledgements

Big chunks of iota were built based on Peter Michaux's [[http://michaux.ca/articles/scheme-from-scratch-introduction][Scheme from

Scratch]] series, which walks through a C implementation of the

metacircular scheme intepreter in [[http://mitpress.mit.edu/sicp/][SICP]].  Other stuff was built by

reading [[http://mitpress.mit.edu/sicp/][SICP]] directly.  I am also working through Lisp in Small

Pieces, so that will probably show up.  Still other stuff I just

hacked out.  Some of it is broken, see below.

** Inspiration

   + [[https://code.google.com/p/femtolisp/][femtolisp]]

   + [[http://piumarta.com/software/maru/][maru]]

** Broken / TODO

   + +Quasiquote (backquote) doesn't nest right+ backquote should work now

   + Variable capture seems to be happening a lot, +maybe because quasiquote is broken, or+ maybe just inherent to common lisp macros in a lisp-1.
