Spec
The basicSpec describes S-expressions whose atoms are simply
text strings that contain alphanumeric characters and a small
set of punctuation. It does no parsing of numbers or other data
types, and will accept tokens that typical Lisp implementations
would find nonsensical (like 77foo).
Atoms recognized by the basicSpec are any string matching the
regular expression [A-Za-z0-9+*<>/=!?-]+.
basicParser :: SExprParser Text (SExpr Text) Source
A SExprParser that understands atoms to be sequences of
alphanumeric characters as well as the punctuation
characters [-*/+<>=!?], and does no processing of them.
>>>decode basicParser "(1 elephant)"Right [SCons (SAtom "1") (SCons (SAtom "elephant") SNil)]
basicPrinter :: SExprPrinter Text (SExpr Text) Source
A SExprPrinter that prints textual atoms directly (without quoting
or any other processing) onto a single line.
>>>encode basicPrinter [L [A "1", A "elephant"]]"(1 elephant)"
