  1. Reformatting the FF test

    committed Sep 11, 2012
  2. Fixing the evaluation of the FF metho

    Finally think I have things working.

  3. Fixed the problem with cond.

    The if statement in COND needed to be reversed - we check for false or :NIL
    instead of checking for true or !:NIL

  1. Fixing the tests, and the code.

    Moving closer to getting the evaluator to really work.
    Looks like my implementations of evaluation of car, cdr were very wrong.
    Now i see that my implementation of cond is broken (probably due to using
    ruby booleans for some return values and checking for :NIL/:T elsewhere).
    Left debug statements in the code to help me remmeber where I was.

  1. Merge branch 'using_NIL_T_instead_of_true_false'

    * using_NIL_T_instead_of_true_false:
      fixing a todo
      now the main evaluator code is working
      trying to fix COND by first refactoring to use T and NIL instead of true/false

  1. Finished implementation of Labels (but...)

    The implementation seems to do too much evaluation - i kept having to quote
    stuff oddly.

  2. Another part of LABELS implementation done

    Now works by replacing bindings
    committed Aug 11, 2012
  3. Partly done with implementation of LABELS

    It is not yet adding the new binding to the existing bindings.
    committed Aug 11, 2012
  4. Implmented COND

    Surprised that I have not yet defined a :T symbol - only :NIL
    Perhaps :T will be an initial value in the env argument to EVAL?

  1. Small refactoring in EVAL

    committed Aug 10, 2012
  2. Fixing small problem with eval definition about handling atoms

    The problem was that it said just to return assoc(x,a) and that is wrong.
    It should be cadr[assoc[x;a]]
    committed Aug 10, 2012
  3. Starting to implement EVAL

    Handling atoms, and the following functions: QUOTE, ATOM, EQ
    committed Aug 10, 2012
  4. adding CONS

    committed Aug 10, 2012
  5. The start of YarLisp - ATOM, EQ, CAR, CDR

    ATOM are defined currently as non-Arrays - this is not really right
    CAR & CDR are defined for Arrays only - hope to redefine after CONS
