Defines a lexer, called as a function of the given NAME, and returning
the matched token-class, image, and image-length as values. The body
consists of token-class definitions, each being a list of a regular
expression, the name of the class, and an optional filter.
Unless PRIORITY-ONLY is true, the longest match will win, and
rule-priority will only be used to break ties. Otherwise, the first
match wins.
Example:
(deflexer lexer ()
("[0-9]+" number parse-integer)
("[a-zA-Z]" letter))
(lexer "2pi" 1)
Returns a lexer function. The DEFS consists of token-class definitions, each being a list of a regular expression, the name of the class, and an optional filter. The returned function takes as arguments an input sequence and an optional start position, and returning the matched token-class, image, and image-length as values.
Unless PRIORITY-ONLY is true, the longest match will win, and
rule-priority will only be used to break ties. Otherwise, the first
match wins.
Example:
(let ((lexer (make-lexer ’(("[0-9]+" number parse-integer)
("[a-zA-Z]" letter)))))
(funcall lexer "2pi" 1))
