maxpc.inputThe generic _input_ interface allows extensions to parse other _types_ of
_input sources_. To add a new _input source type_, {make-input} has to be
specialized on that _type_. The following methods have to be defined for
_inputs_:
+ {input-empty-p}
+ {input-first}
+ {input-rest}
The following methods can optionally be defined for _inputs_:
+ {input-position}
+ {input-element-type}

maxpc_Max’s Parser Combinators_¹ is a simple and pragmatic library for writing
parsers and lexers based on combinatory parsing. MaxPC is capable of
parsing deterministic, context-free languages, provides powerful tools for
parse tree transformation and error handling, and can operate on
_sequences_ and _streams_. It supports unlimited backtracking, but does not
implement [Packrat Parsing](http://pdos.csail.mit.edu/~baford/packrat/thesis/).
Instead, MaxPC achieves good performance through its optimized primitives,
and explicit separation of matching and capturing input. In practice, MaxPC
parsers perform better on typical computer languages—when compared to
Packrat parsers—at the expense of not producing linear-time parsers.²
+ 1. MaxPC is a complete rewrite of [MPC](https://github.com/eugeneia/mpc)
with was in turn a fork of Drew Crampsie’s
[Smug](http://smug.drewc.ca/).
+ 2. See [MaxPC: Why? How? / Packrat Parsing](http://mr.gy/blog/maxpc.html#section-3-1)
on why the book keeping costs of Packrat parsing diminish the gain in
execution time for typical grammars and workloads.
< Basic Concepts
MaxPC _parsers_ are _functions_ that accept an [input](#section-4) as
their only argument and return three values: the remaining _input_ or
{nil}, a _result value_ or {nil}, and a _generalized boolean_ that
indicates if a _result value_ is present. The _type_ of a parser is:
{(function (}_input_{) (or} _input_ {null) * boolean)}
A parser can either succeed or fail when applied to an input at a given
position. A succeeding parser is said to _match_. When a parser matches it
can optionally produce a _result value_, which may be processed by its
parent parsers. New parsers can be created by composing existing parsers
using built-in or user defined _parser combinators_. A parser combinator
is a higher-order _function_ that includes one or more parsers as its
arguments and returns a parser.
By convention, all parsers are defined as higher-order _functions_ that
return the respective parser, even if they are nullary. For instance, the
{?end} parser is obtained using the form “{(?end)}”.
A lexical convention is used to make three different types of parsers
easily distinguishable:
+ Parsers whose names start with a question mark ({?}) never produce a
result value.
+ Parsers whose names start with an equals sign ({=}) always produce a
result value.
+ Parsers whose names start with a percent symbol ({%}) may produce a
result value depending on their arguments.
>
< Example
We will define a parser for a simplistic grammar for Email addresses of
the form:
_email‑address_ := _user_ {@} _host_
First we define a parser for the valid characters in the _user_ and _host_
parts of an address. Just for this example, we choose these to be
alphanumeric characters and then some. {?address-character} uses the {%or}
combinator to form the union of two instances of {?satisfies} that match
different sets of characters.
#code#
(defun ?address-character ()
(%or (?satisfies ’alphanumericp)
(?satisfies (lambda (c)
(member c ’(#\- #\_ #\. #\+))))))
#
Then we use {?address-character} to implement our address parser which
matches two sequences of “address characters” separated by an {@}
character, and produces a list of user and host components as its result
value. We match {?address-character} one or more times using {%some}, and
produce the matched subsequence as the result value using {=subseq}. Both
parts of the address separated by an _@_ character are matched in sequence
using {=list}, whose result value is finally transformed by
{=destructure}.
#code#
(defun =email-address ()
(=destructure (user _ host)
(=list (=subseq (%some (?address-character)))
(?eq #\@)
(=subseq (%some (?address-character))))
(list user host)))
#
We can now apply {=email-address} using {parse}:
#code#
(parse "foo_bar@example.com" (=email-address))
⇒ ("foo_bar" "example.com"), T, T
(parse "!!!@@@.com" (=email-address))
⇒ NIL, NIL, NIL
(parse "foo_bar@example.com@baz" (=email-address))
⇒ ("foo_bar" "example.com"), T, NIL

< Overview
{parse} is the entry point of {MaxPC}. It applies a parser to an input and
returns the parser’s result value, and two _boolean_ values indicating if
the parser matched and if there is unmatched input remaining,
respectively.
< Basic Parsers
+ {?end} matches only when there is no further input.
+ {=element} unconditionally matches the next element of the input
_sequence_.
+ {=subseq} produces the subsequence matched by its argument as its
result value.
+ {?satisfies}, {?test}, and {?eq} match input conditionally.
+ {%maybe} matches, even if its argument fails to match.
>
< Logical Combinators
+ {%or} forms the union of its arguments.
+ {%and} forms the intersection of its arguments.
+ {%diff} forms the difference of its arguments.
+ {?not} negates its argument.
>
< Sequence Combinators
+ {?seq} matches its arguments in sequence.
+ {=list} matches its arguments in sequence and produces a list of their
results as its result value.
+ {%any} matches its argument repeatedly any number of times.
+ {%some} matches its argument repeatedly one or more times.
>
< Transformation
+ {=transform} produces the result of applying a _function_ to its
argument’s result value as its result value.
+ {=destructure} is a convenient destructuring _macro_ on top of
{=transform}.
>
< Error Handling
+ {?fail} never matches and evaluates its body when it is called.
+ {%handler-case} and {%restart-case} allow you to set up _handlers_ and
_restarts_ across parsers.
+ {get-input-position} can be called in error situations to retrieve the
current position in the input.

< Caveat: Recursive Parsers
A recursive parser can not refer to itself by its constructor, but must
instead call itself by _symbol_—calling its constructor would otherwise
result in unbounded recursion. In order to do so the parser _function_
needs to be _bound_ in the _function namespace_ using {setf}. The example
below implements a parser for balanced parentheses, and illustrates how to
avoid this common caveat.
#code#
(defun ?parens ()
(?seq (?eq #\() (%maybe ’?parens/parser) (?eq #\))))
(setf (fdefinition ’?parens/parser) (?parens))
(parse "((()))" (?parens)) ⇒ NIL, T, T

*Description:*
{*chunk-size*} controls the size by which the buffer used for _stream inputs_ grows, and the number of elements read at a time when parsing from _streams_ of _type_ {file-stream}.
*Description:*
{*element-type*} can be set to enforce a specific stream element type when reading from _stream inputs_. This can be useful when dealing with bivalent streams.
*Value Type:*
a _list_ of _characters_.
*Description:*
The _value_ of {*whitespace*} is a _list_ of _characters_ considered to be _whitespace characters_.

_restart‑clause_, _parser‑form_ is evaluated and the resulting _parser_ is
applied.
*Examples:*
#code#
(parse "012x3"

*See Also:*
{restart-case}.
*Arguments and Values:*
_lambda‑list_—a _destructuring lambda list_.
_parser_—a _parser_.
_forms_—an _implicit progn_.
*Description:*
{=destructure} matches _parser_ and destructures its result value as if by
{destructuring-bind}. The {_} (underscore) symbol can occur in _lambda‑list_
any number of times, and is substituted with a _fresh_, _uninterned symbol_
and declared {ignorable}. If _parser_ matches {=destructure} evaluates
_forms_ and produces the value of the last _form_ as its result value. If no
_forms_ are supplied the value of the last, _interned_ variable defined in
_lambda‑list_ is produced as the result value instead.
*Examples:*
#code#
(parse ’(10 % 3) (=destructure (x _ y)
(=list (=element) (?eq ’%) (=element))
(mod x y)))
→ 1, T, T
(parse "a," (=destructure (x _)
(=list (=element) (?eq #\,))))
→ #\a, T, T
(parse ’(a b c) (=destructure (x &rest xs)
(%some (=element))))
→ ’(B C), T, T
#
*Exceptional Situations:*
If the result value of _parser_ does not match the destructuring pattern, an
_error_ of _type_ {program-error} is signaled.
*See Also:*
{destructuring-bind}
*Arguments and Values:*
_forms_—_forms_.
*Description:*
{?fail} always fails to match, and evaluates _forms_ when it is applied.
*Examples:*
#code#
(parse ’(a b c) (?fail (format t "Position: ~a~%"
(get-input-position))))
▷ Position: 0
→ NIL, NIL, NIL
#
*Arguments and Values:*
_test_—a _designator_ for a _function_ that returns a _generalized boolean_.
_arguments_—_objects_.
_parser_—a _parser_. The default is {(=element)}.
*Description:*
{?test} matches _parser_ if its result value _satisfies the test_ with
_arguments_ as additional arguments to _test_.
*Examples:*
#code#
(parse ’(a) (?test (’member ’(a b)))) ⇒ NIL, T, T
(flet ((power-of-p (n e) (= (mod n e) 0)))
(parse ’(42) (?test (#’power-of-p 2)))) ⇒ NIL, T, T
#
*Notes:*
#code#
(?test ({fun} {args}*}))
≡ (?satisfies (lambda (x)
(funcall {fun} x {args}*)))
#
*Exceptional Situations:*
If _test_ accepts less arguments than the number of _arguments_ plus one an
_error_ of _type_ {program-error} is signaled.
*See also:*

*Description:*
{%and} applies _parsers_, and matches the last _parser_ only if all previous
_parsers_ succeed. If the last _parser_ produces a result value then {%and}
produces that value as its result value. It can be said that {%and} forms
the set intersection of _parsers_.
*Examples:*
#code#
(parse ’(:foo) (%and (?satisfies ’symbolp)
(?satisfies ’keywordp)))
→ NIL, T, T
(parse ’(foo) (%and (?satisfies ’symbolp)
(?satisfies ’keywordp)))
→ NIL, NIL, NIL
(parse ’(foo) (%and))
→ NIL, NIL, NIL
(parse ’(foo) (%and (?satisfies ’symbolp)
