Elf M. Sternberg ae416ff5c4 [feat] Added length count to utilities. 2015-07-22 21:05:20 -07:00
Elf M. Sternberg 416ad7ac20 [refactor] Change the internal representation for is-a-list 
This update locks us into a late ECMA-5 implementation (no ECMA-3 for
you!) but it improves the way this representation works and is presented
to users.  It also corresponds (unsurprisingly) to the format used by
my experimental LiSP implementation, thus making my life easier.

Also: Included unit tests to ensure that nilp, listp, pairp, and cellp
all detect the correct matrix of... things.

Elf M. Sternberg 279ba3e7a2 Added nil/nil testing. Still don't like the lack of an identity function. 2015-06-27 10:45:20 -07:00
Elf M. Sternberg c5008cdb5d Added fundamental traversal tests. They passed (of course, otherwise many 
other things would already be failing), but I can't believe I forgot them.
Some TDD'r I am.

Elf M. Sternberg 54da8c6b65 Changed the list structure to not respect cons(nil, nil) == nil. 
I think this is a mistake, but at the moment I'm not clever enough to
figure out how to properly acknowledge an end-of-list without a special
sentinel, which I'm trying to avoid.

TODO: Revisit this.

Modified Makefile to produce JUnit-compatible error messages.

Style (coffee-lint cleanup)

Elf M. Sternberg 3a59d3f2f1 Metacadr's reuse doesn't kill people. Mutation kills people! 
Updated metacadr's test suite to ensure that re-using a
metacadr-generated function does not lead to crashes.  Saw this a lot in
early versions of LISP.
