e61dc0b6a4 [lexer] Add failing test for issue #12 2018-08-27 06:56:48 -07:00
c14c939ad3 [parser] ListParser can handle lists of more than 2 elements 😮
As ListParser sees items within its list, it assembles a vector of Pairs. When
the parser encounters ')', it assembles the pairs into an actual linked list and
returns the root Pair.

This work also revealed that I was asserting incorrectly in my single_pair test.
It should return Null instead of an empty Pair. Neat.

Closes #17.

b0b4699476 [lexer] Rewrite the Lexer!
Implement structs for each state in the lexer. The State objects are responsible
for determining how to handle a character and emit a Result  indicating to the
driver (the Lexer struct) how to proceed.
