Parser modifier macro: cache parser as label with argument list equal under equal in global cache.
Parser modifier macro: cache parser as label in global cache.
Parser modifier: add recursion curtailing to PARSER, naming the curtailed parser NAME. Left recursive parser parser will only be nested once per remaining length of the input string. Note: this is only necessary for a limited class of left recursive parsers. Non-left recursive parsers should be implemented using just ‘named?‘, and most left-recursive parsers using that in combination with ‘chainl1?‘. Also see ‘expression?‘.
Define cached parser with arguments.
Define cached parser of no arguments.
Parser modifier macro: parser will be built when called. This is necessary for left-recursive parsers.
Combinator: use do-like notation to sequentially link parsers. (<- name parser) allows capturing of return values.
Like NAMED-SEQ*, but with MDO syntax: the last element must be a parser.
Non-backtracking parser: This is similar to MDO, except that constructed parsers cannot depend on
the results of previous ones and the final form is not used as a parser, but is automatically used
to construct the result. All names bound using the (<- name parser) construct are only available in
that final form.
This parser generator is useful when full generality of MDO is not necessary, as it is implemented non-recursively and has better memory performance.

This parser generator is useful when full generality of MDO is not necessary, as it is implemented non-recursively and has better memory performance.
Parser macro: give BODY a NAME, so it can refer to itself without causing generator recursion.

Combinator: all alternatives from multiple parsers

Parser: Reduce a sequence of terms with unary/binary operators with precedence.
OPERATORS is a list of (op-parser :left/:right/:unary), where OP-PARSER is a parser consuming
an operator and returning a reduction function. Highest precedence first.
Non-backtracking parser: Find first q
Non-backtracking parser: Find first q after some sequence of p.
Non-backtracking parser: Find first q after some sequence of p. Return cons of list of p-results and q
Parser: Find q after some sequence of p, earliest match first. Return cons of list of p-results and q
Parser: Find q after some sequence of p, earliest matches first.
Non-backtracking parser: Find a sequence of p terminated by q, doesn’t consume q.
Non-backtracking parser: Find a sequence of p terminated by single token q, which is not consumed.
Parser: Find a sequence of p terminated by q, doesn’t consume q.
Parser: Find q, earliest match first.
Parser modifier: fully realize result from parser
Non-backtracking parser: Find a sequence of tokens terminated by single token, which is not consumed.
Non-backtracking parser: Find a sequence of tokens terminated by one for which predicate returns true, which is not consumed.
Obtain all of the results within PARSE-RESULT, starting with the current one, potentially realising the non-realised ones in the backing store.
Parser: apply function to result of p
Non-backtracking parser: accept integer, consuming as many digits as possible
Parser: accept an integer, return as integer.
Primitive parser: consume item from input and return it.
Parser: accept alphabetic character
Parser: accept lowercase character
Document all potential results of CONTINUATION as a PARSE-RESULT object.
Non-backtracking parser: collect as many of first result of parser as possible
Non-backtracking parser: accept as many as possible, and at least one, of parser
Parser: accept one or more of expression accepted by parser
Parser: accept zero or more repetitions of expression accepted by parser
Parser modifier: memoizes the parser, which if called again at a given position it will return a result immediately. LABEL is used for memoization key, use explicit one if the parser is used in multiple places.
Non-backtracking parser: accept natural number, consuming as many digits as possible
Parser: accept natural numbers
Parser: parse a sequence of p, like between?, but with p possibly nested in brackets.
Non-backtracking parser: result of p or nil
Parser: result of p or nil
Parse a sequence (where a sequence is any object which implementes CONTEXT interface), return a PARSE-RESULT object. All returned values may share structure.
Parse a sequence (where a sequence is any object which implementes CONTEXT interface) and
return as multiple values the first result, whether the parse was incomplete, whether it was
successful, the context front and the position frequency table. The context front is an object
containing the context which most advances the input sequence and a list of lists of parser
tags which were current at that point, which allows approximate error reporting. It will be
NIL if the parse is successful and complete. The position frequency table serves profiling
needs and maps sequence positions to the number of times a new context was created at that
position – which should provide a rough hint at how problematic that particular spot is.
If COMPLETE is T, return the first parse to consume the input
completely. If COMPLETE is :FIRST return the first result only when it the whole input was consumed,
or immediately return nil.
Synonym for parse-sequence. Parse a string, return a PARSE-RESULT object. All returned values may share structure.
