Mock Census Parser
Must read a file via HTTP or on the local filesystem.
(The file has ostensibly just passed validation and needs no further error-checking)
The file contains three newline-delimited directives per block and one EOF directive.
Each directive has a number of space-delimited attributes.
The directives appear in this order:
-
Head
- this must be the start of the block. Represents the head of household- name - first name of the individual
- gender
- eye_color
- hair_color
- height - feet as a float
-
Depedent
- 0 or many may exist. Represents children, spouse, etc- name
- gender
- age - 'minor' or 'adult'
- height
-
End
- must close the block before the next 'Head' -
SUPER-END
- a special end-of-file (EOF) markerend
MUST precedeSUPER-END

Variations from the Spec
My implementation is written in JavaScript (which is like LISP, not at all like Java). I take advantage of some JavaScript-isms.
In my implementation I also handle #
comments as well as some extremely minimalistic error-checking.
