Accepts a string which is a regular expression in
+Perl syntax and returns a closure which will scan strings for this
+regular expression. The second value is only returned if *ALLOW-NAMED-REGISTERS* is true. It represents a list of strings mapping registers to their respective names - the first element stands for first register, the second element for second register, etc. You have to store this value if you want to map a register number to its name later as scanner doesn't capture any information about register names. If a register isn't named, it has NIL as its name.
+
+The mode keyword arguments are equivalent to the
+"imsx" modifiers in Perl. The
+destructive keyword will be ignored.
+
+The function accepts most of the regex syntax of Perl 5.8 as described
+in man
+perlre including extended features like non-greedy
+repetitions, positive and negative look-ahead and look-behind
+assertions, "standalone" subexpressions, and conditional
+subpatterns. The following Perl features are (currently) not
+supported:
+
+
+
+
(?{ code }) and (??{ code }) because
+they obviously don't make sense in Lisp.
+
+
\N{name} (named characters), \x{263a}
+(wide hex characters), \l, \u,
+\L, and \U
+because they're actually not part of Perl's regex syntax - but see CL-INTERPOL.
+
+
\X (extended Unicode), and \C (single
+character). But you can of course use all characters
+supported by your CL implementation.
+
+
Posix character classes like [[:alpha]].
+Use Unicode properties instead.
+
+
\G for Perl's pos() because we don't have it.
+
+
+
+Note, however, that \t, \n, \r,
+\f, \a, \e, \033
+(octal character codes), \x1B (hexadecimal character
+codes), \c[ (control characters), \w,
+\W, \s, \S, \d,
+\D, \b, \B, \A,
+\Z, and \zare supported.
+
+Since version 1.3.0, CL-PPCRE offers support for AllegroCL's(?<name>"<regex>") named registers and \k<name> back-references syntax, have a look at *ALLOW-NAMED-REGISTERS* for details.
+
+Since version 2.0.0, CL-PPCRE
+supports named properties
+(\p and \P), but only the long form with
+braces is supported, i.e. \p{Letter}
+and \p{L} will work while \pL won't.
+
+The keyword arguments are just for your
+convenience. You can always use embedded modifiers like
+"(?i-s)" instead.
In this case function should be a
+scanner returned by another invocation
+of CREATE-SCANNER. It will be returned as is. You can't
+use any of the keyword arguments because the scanner has already been
+created and is immutable.
+
+This is similar to CREATE-SCANNER for regex strings above but
+accepts a parse tree as its first argument. A parse tree is an S-expression
+conforming to the following syntax:
+
+
+
+
Every string and character is a parse tree and is treated
+literally as a part of the regular expression,
+i.e. parentheses, brackets, asterisks and such aren't special.
+
+
The symbol :VOID is equivalent to the empty string.
+
+
The symbol :EVERYTHING is equivalent to Perl's dot,
+i.e it matches everything (except maybe a newline character depending
+on the mode).
+
+
The symbols :WORD-BOUNDARY and
+:NON-WORD-BOUNDARY are equivalent to Perl's
+"\b" and "\B".
+
+
The symbols :DIGIT-CLASS,
+:NON-DIGIT-CLASS, :WORD-CHAR-CLASS,
+:NON-WORD-CHAR-CLASS,
+:WHITESPACE-CHAR-CLASS, and
+:NON-WHITESPACE-CHAR-CLASS are equivalent to Perl's
+special character classes"\d",
+"\D", "\w",
+"\W", "\s", and
+"\S" respectively.
+
+
The symbols :START-ANCHOR, :END-ANCHOR,
+:MODELESS-START-ANCHOR,
+:MODELESS-END-ANCHOR, and
+:MODELESS-END-ANCHOR-NO-NEWLINE are equivalent to Perl's
+"^", "$",
+"\A", "\Z", and
+"\z" respectively.
+
+
The symbols :CASE-INSENSITIVE-P,
+:CASE-SENSITIVE-P, :MULTI-LINE-MODE-P,
+:NOT-MULTI-LINE-MODE-P, :SINGLE-LINE-MODE-P,
+and :NOT-SINGLE-LINE-MODE-P are equivalent to Perl's
+embedded modifiers"(?i)",
+"(?-i)", "(?m)",
+"(?-m)", "(?s)", and
+"(?-s)". As usual, changes applied to modes are
+kept local to the innermost enclosing grouping or clustering
+construct.
+
+
(:FLAGS {<modifier>}*) where
+<modifier> is one of the modifier symbols from
+above is used to group modifier symbols. The modifiers are applied
+from left to right. (This construct is obviously redundant. It is only
+there because it's used by the parser.)
+
+
(:SEQUENCE {<parse-tree>}*) means a
+sequence of parse trees, i.e. the parse trees must match one after
+another. Example: (:SEQUENCE #\f #\o #\o) is equivalent
+to the parse tree "foo".
+
+
(:GROUP {<parse-tree>}*) is like
+:SEQUENCE but changes applied to modifier flags (see
+above) are kept local to the parse trees enclosed by this
+construct. Think of it as the S-expression variant of Perl's
+"(?:<pattern>)" construct.
+
+
(:ALTERNATION {<parse-tree>}*) means an
+alternation of parse trees, i.e. one of the parse trees must
+match. Example: (:ALTERNATION #\b #\a #\z) is equivalent
+to the Perl regex string "b|a|z".
+
+
(:BRANCH <test>
+<parse-tree>) is for conditional regular
+expressions. <test> is either a number which
+stands for a register or a parse tree which is a look-ahead or
+look-behind assertion. See the entry for
+(?(<condition>)<yes-pattern>|<no-pattern>)
+in man
+perlre for the semantics of this construct. If
+<parse-tree> is an alternation is
+must enclose exactly one or two parse trees where the second
+one (if present) will be treated as the "no-pattern" - in
+all other cases <parse-tree> will be treated
+as the "yes-pattern".
+
+
(:POSITIVE-LOOKAHEAD|:NEGATIVE-LOOKAHEAD|:POSITIVE-LOOKBEHIND|:NEGATIVE-LOOKBEHIND
+<parse-tree>) should be pretty obvious...
+
+
(:GREEDY-REPETITION|:NON-GREEDY-REPETITION
+<min> <max>
+<parse-tree>) where
+<min> is a non-negative integer and
+<max> is either a non-negative integer not
+smaller than <min> or NIL will
+result in a regular expression which tries to match
+<parse-tree> at least
+<min> times and at most
+<max> times (or as often as possible if
+<max> is NIL). So, e.g.,
+(:NON-GREEDY-REPETITION 0 1 "ab") is equivalent
+to the Perl regex string "(?:ab)??".
+
+
(:STANDALONE <parse-tree>) is an
+"independent" subexpression, i.e. (:STANDALONE
+"bar") is equivalent to the Perl regex string
+"(?>bar)".
+
+
(:REGISTER <parse-tree>) is a capturing
+register group. As usual, registers are counted from left to right
+beginning with 1.
+
+
(:NAMED-REGISTER <name> <parse-tree>) is a named capturing
+register group. Acts as :REGISTER, but assigns <name> to a register too. This <name> can be later referred to via :BACK-REFERENCE. Names are case-sensitive and don't need to be unique. See *ALLOW-NAMED-REGISTERS* for details.
+
+
+
(:BACK-REFERENCE <ref>) is a
+back-reference to a register group. <ref> is
+a positive integer or a string denoting a register name. If there are
+several registers with the same name, the regex engine tries to
+successfully match at least of them, starting with the most recently
+seen register continuing to the least recently seen one, until a match
+is found. See *ALLOW-NAMED-REGISTERS*
+for more information.
+
+
(:PROPERTY|:INVERTED-PROPERTY <property>) is
+a named property (or its inverse) with
+<property> being a function designator or a
+string which must be resolved
+by *PROPERTY-RESOLVER*.
+
+
(:CHAR-CLASS|:INVERTED-CHAR-CLASS
+{<item>}*) where <item>
+is either a character, a character range, a named property
+(see above), or a symbol for a special character class (see above)
+will be translated into a (one character wide) character
+class. A character range looks like
+(:RANGE <char1> <char2>) where
+<char1> and
+<char2> are characters such that
+(CHAR<= <char1> <char2>) is
+true. Example: (:INVERTED-CHAR-CLASS #\a (:RANGE #\D #\G)
+:DIGIT-CLASS) is equivalent to the Perl regex string
+"[^aD-G\d]".
+
+
+
+Because CREATE-SCANNER is defined as a generic function
+which dispatches on its first argument there's a certain ambiguity:
+Although strings are valid parse trees they will be interpreted as
+Perl regex strings when given to CREATE-SCANNER. To
+circumvent this you can always use the equivalent parse tree (:GROUP
+<string>) instead.
+
+Note that CREATE-SCANNER doesn't always check
+for the well-formedness of its first argument, i.e. you are expected
+to provide correct parse trees.
+
+
+The usage of the keyword argument extended-mode obviously
+doesn't make sense if CREATE-SCANNER is applied to parse
+trees and will signal an error.
+
+If destructive is not NIL (the default is
+NIL), the function is allowed to destructively modify
+parse-tree while creating the scanner.
+
+If you want to find out how parse trees are related to Perl regex
+strings, you should play around with
+PARSE-STRING:
+
+
+For the rest of the dictionary, regex can
+always be a string (which is interpreted as a Perl regular
+expression), a parse tree, or a scanner created by
+CREATE-SCANNER. The
+start and end
+keyword parameters are always used as in SCAN.
+
+
+
+
+
+Searches the string target-string
+from start (which defaults to 0) to
+end (which default to the length of
+target-string) and tries to match
+regex. On success returns four values - the start
+of the match, the end of the match, and two arrays denoting the
+beginnings and ends of register matches. On failure returns
+NIL. target-string will be coerced
+to a simple string if it isn't one already. (There's another keyword
+parameter real-start-pos. This one should
+never be set from user code - it is only used internally.)
+
+SCAN acts as if the part of
+target-string between start
+and end were a standalone string, i.e. look-aheads
+and look-behinds can't look beyond these boundaries.
+
+Like SCAN but returns substrings of
+target-string instead of positions, i.e. this
+function returns two values on success: the whole match as a string
+plus an array of substrings (or NILs) corresponding to
+the matched registers. If sharedp is true, the substrings may share structure with
+target-string.
+
+Evaluates statement* with the variables in var-list bound to the
+corresponding register groups after target-string has been matched
+against regex, i.e. each variable is either
+bound to a string or to NIL.
+As a shortcut, the elements of var-list can also be lists of the form (FN VAR) where VAR is the variable symbol
+and FN is a function
+designator (which is evaluated) denoting a function which is to be applied to the string before the result is bound to VAR.
+To make this even more convenient the form (FN VAR1 ...VARn) can be used as an abbreviation for
+(FN VAR1) ... (FN VARn).
+
+If there is no match, the statement* forms are not
+executed. For each element of
+var-list which is NIL there's no binding to the corresponding register
+group. The number of variables in var-list must not be greater than
+the number of register groups. If sharedp is true, the substrings may
+share structure with target-string.
+
+* (register-groups-bind (first second third fourth)
+ ("((a)|(b)|(c))+" "abababc" :sharedp t)
+ (list first second third fourth))
+("c" "a" "b" "c")
+
+* (register-groups-bind (nil second third fourth)
+ ;; note that we don't bind the first and fifth register group
+ ("((a)|(b)|(c))()+" "abababc" :start 6)
+ (list second third fourth))
+(NIL NIL "c")
+
+* (register-groups-bind (first)

+NIL

+ (list fname lname (encode-universal-time 0 0 0 date month year 0)))
+("Frank" "Zappa" 1292889600)
+
+A macro which iterates over target-string and
+tries to match regex as often as possible
+evaluating statement* with
+match-start, match-end,
+reg-starts, and reg-ends bound
+to the four return values of each match (see SCAN) in turn. After the last match,
+returns result-form if provided or
+NIL otherwise. An implicit block named NIL
+surrounds DO-SCANS; RETURN may be used to
+terminate the loop immediately. If regex matches
+an empty string, the scan is continued one position behind this match.
+
+This is the most general macro to iterate over all matches in a target
+string. See the source code of DO-MATCHES, ALL-MATCHES, SPLIT, or REGEX-REPLACE-ALL for examples of its
+usage.
+Like DO-SCANS but doesn't bind
+variables to the register arrays.
+
+* (defun foo (regex target-string &key (start 0) (end (length target-string)))
+ (let ((sum 0))
+ (do-matches (s e regex target-string nil :start start :end end)
+ (incf sum (- e s)))
+ (format t "~,2F% of the string was inside of a match~%"
+ ;; note: doesn't check for division by zero
+ (float (* 100 (/ sum (- end start)))))))
+
+FOO
+
+* (foo "a" "abcabcabc")
+33.33% of the string was inside of a match
+NIL
+* (foo "aa|b" "aacabcbbc")
+55.56% of the string was inside of a match
+NIL
+
+Like DO-MATCHES but binds
+match-var to the substring of
+target-string corresponding to each match in turn. If sharedp is true, the substrings may share structure with
+target-string.
+
+Iterates over target-string and tries to match regex as often as
+possible evaluating statement* with the variables in var-list bound to the
+corresponding register groups for each match in turn, i.e. each
+variable is either bound to a string or to NIL. You can use the same shortcuts and abbreviations as in REGISTER-GROUPS-BIND. The number of
+variables in var-list must not be greater than the number of register
+groups. For each element of
+var-list which is NIL there's no binding to the corresponding register
+group. After the last match, returns result-form if provided or NIL
+otherwise. An implicit block named NIL surrounds DO-REGISTER-GROUPS;
+RETURN may be used to terminate the loop immediately. If regex matches
+an empty string, the scan is continued one position behind this
+match. If sharedp is true, the substrings may share structure with
+target-string.
+
+* (do-register-groups (first second third fourth)

+ (nreverse result))
+(12 * 15 - 42 / 3)
+
+Returns a list containing the start and end positions of all matches
+of regex against
+target-string, i.e. if there are N
+matches the list contains (* 2 N) elements. If
+regex matches an empty string the scan is
+continued one position behind this match.
+
+* (all-matches "a" "foo bar baz")
+(5 6 9 10)
+
+* (all-matches "\\w*" "foo bar baz")
+(0 3 3 3 4 7 7 7 8 11 11 11)
+
+Matches regex against
+target-string as often as possible and returns a
+list of the substrings between the matches. If
+with-registers-p is true, substrings corresponding
+to matched registers are inserted into the list as well. If
+omit-unmatched-p is true, unmatched registers will
+simply be left out, otherwise they will show up as
+NIL. limit limits the number of
+elements returned - registers aren't counted. If
+limit is NIL (or 0 which is
+equivalent), trailing empty strings are removed from the result list.
+If regex matches an empty string, the scan is
+continued one position behind this match. If sharedp is true, the substrings may share structure with
+target-string.
+
+This function also tries hard to be
+Perl-compatible - thus the somewhat peculiar behaviour.
+
Try to match target-string
+between start and end against
+regex and replace the first match with
+replacement. Two values are returned; the modified
+string, and T if regex matched or
+NIL otherwise.
+
+replacement can be a string which may contain the
+special substrings "\&" for the whole
+match, "\`" for the part of
+target-string before the match,
+"\'" for the part of
+target-string after the match,
+"\N" or "\{N}" for the
+Nth register where N is a positive integer.
+
+replacement can also be a function
+designator in which case the match will be replaced with the
+result of calling the function designated by
+replacement with the arguments
+target-string, start,
+end, match-start,
+match-end, reg-starts, and
+reg-ends. (reg-starts and
+reg-ends are arrays holding the start and end
+positions of matched registers (or NIL) - the meaning of
+the other arguments should be obvious.)
+
+If simple-calls is true, a function designated by
+replacement will instead be called with the
+arguments match, register-1,
+..., register-n where match is
+the whole match as a string and register-1 to
+register-n are the matched registers, also as
+strings (or NIL). Note that these strings share structure with
+target-string so you must not modify them.
+
+Finally, replacement can be a list where each
+element is a string (which will be inserted verbatim), one of the
+symbols :match, :before-match, or
+:after-match (corresponding to
+"\&", "\`", and
+"\'" above), an integer N
+(representing register (1+ N)), or a function
+designator.
+
+If preserve-case is true (default is
+NIL), the replacement will try to preserve the case (all
+upper case, all lower case, or capitalized) of the match. The result
+will always be a fresh
+string, even if regex doesn't match.
+
This is the designator for a function responsible
+for resolving named properties like \p{Number}. If
+CL-PPCRE encounters a \p or a \P it expects
+to see an opening curly brace immediately afterwards and will then
+read everything following that brace until it sees a closing curly
+brace. The resolver function will be called with this string and must
+return a corresponding unary test function which accepts a character
+as its argument and returns a true value if and only if the character
+has the named property. If the resolver returns NIL
+instead, it signals that a property of that name is unknown.
+
+If the value
+of *PROPERTY-RESOLVER*
+is NIL (which is the default), \p and \P in regex
+strings will simply be treated like p or P
+as in CL-PPCRE 1.4.1 and earlier. Note that this does not affect
+the validity of (:PROPERTY <name>)
+parts in S-expression syntax.
+
+Any symbol (unless it's a keyword with a special meaning in parse
+trees) can be made a "synonym", i.e. an abbreviation, for another parse
+tree by this accessor. PARSE-TREE-SYNONYM returns NIL if symbol isn't a synonym yet.
+
This variable controls whether scanners take into
+account all characters of your CL implementation or only those
+the CHAR-CODE
+of which is not larger than its value. The default is
+CHAR-CODE-LIMIT,
+and you might see significant speed and space improvements during
+scanner creation if, say, your target strings only
+contain ISO-8859-1
+characters and you're using a Lisp implementation
+where CHAR-CODE-LIMIT has a value much higher
+than 256. The test suite will automatically
+set *REGEX-CHAR-CODE-LIMIT* to 256 while you're running
+the default test.
+
+Note: Due to the nature of LOAD-TIME-VALUE and the compiler macro for SCAN and other functions, some
+scanners might be created in a null
+lexical environment at load time or at compile time so be careful
+to which value *REGEX-CHAR-CODE-LIMIT* is bound at that
+time. The default value should always yield correct results unless you
+play dirty tricks with implementation-dependent behaviour, though.
Usually, the scanners created
+by CREATE-SCANNER (or
+implicitly by other functions and macros) will use the standard
+function SEARCH
+to check for constant strings at the start or end of the regular
+expression. If *USE-BMH-MATCHERS* is true (the default
+is NIL),
+fast Boyer-Moore-Horspool
+matchers will be used instead. This will usually be faster but
+can make the scanners considerably bigger. Per BMH matcher - there
+can be up to two per scanner - a fixnum array of
+size *REGEX-CHAR-CODE-LIMIT*
+is allocated and closed over.
+
+Whether character classes should be compiled into look-ups into O(1)
+data structures. This is usually fast but will be costly in terms of
+scanner creation time and might be costly in terms of size if
+*REGEX-CHAR-CODE-LIMIT*
+is high. This value will be used as the kind
+keyword argument
+to CREATE-OPTIMIZED-TEST-FUNCTION
+- see there for the possible non-NIL values. The default
+value (NIL) should usually be fine unless you're sure
+that you absolutely have to optimize some character classes for speed.
+
+If this value is true (the default is NIL),
+CL-PPCRE will support \Q and \E in regex
+strings to quote (disable) metacharacters. Note that this entails a
+slight performance penalty when creating scanners because (a copy of) the regex
+string is modified (probably more than once) before it
+is fed to the parser. Also, the parser's syntax error messages will complain
+about the converted string and not about the original regex string.

+strings to provide named registers and back-references as in AllegroCL. name is has to start with a letter and can contain only alphanumeric characters or minus sign. Names of registers are matched case-sensitively.
+The parse tree syntax is not affected by the *ALLOW-NAMED-REGISTERS* switch, :NAMED-REGISTER and :BACK-REFERENCE forms are always resolved as expected. There are also no restrictions on register names in this syntax except that they have to be strings.

Given a regular expression which has a constant
+suffix, such as (a|b)+x whose constant suffix
+is x, the scanners created
+by CREATE-SCANNER will
+attempt to optimize by searching for the position of the suffix prior
+to performing the full match. In many cases, this is an optimization,
+especially when backtracking is involved on small strings. However, in
+other cases, such as incremental parsing of a very large string, this
+can cause a degradation in performance, because the entire string is
+searched for the suffix before an otherwise easy prefix match failure
+can occur. The variable *LOOK-AHEAD-FOR-SUFFIX*, whose
+default is T, can be used to selectively control this
+behavior.
+
Converts the regex
+stringstring into a parse tree.
+Note that the result is usually one possible way of creating an
+equivalent parse tree and not necessarily the "canonical" one.
+Specifically, the parse tree might contain redundant parts which are
+supposed to be excised when a scanner is created.
+
+
+Given a unary test function test-function which is
+applicable to characters returns a function which yields the same
+boolean results for all characters with character codes
+from start to (excluding) end.
+If kind
+is NIL, test-function will simply be
+returned. Otherwise, kind should be one of:
+
+
:HASH-TABLE
+
The function builds a hash table representing all characters which
+satisfy the test and returns a closure which checks if a character is
+in that hash table.
+
:CHARSET
+
Instead of a hash table the function uses a "charset"
+which is a data structure using non-linear hashing and optimized to
+represent (sparse) sets of characters in a fast and space-efficient
+way (contributed by Nikodemus Siivola).
+
:CHARMAP
+
Instead of a hash table the function uses a bit vector to
+represent the set of characters.
+
+You can also use :HASH-TABLE* or :CHARSET*
+which are like :HASH-TABLE and :CHARSET but
+use the complement of the set if the set contains more than half of
+all characters between start
+and end. This saves space but needs an additional
+pass across all characters to create the data structure. There is no
+corresponding :CHARMAP*kind as the bit vectors are
+already created to cover the smallest possible interval which contains
+either the set or its complement.
+
+This is a simple utility function used when *ALLOW-QUOTING* is
+true. It returns a string STRING' where all
+non-word characters (everything except ASCII characters, digits and
+underline) of STRING are quoted by prepending a
+backslash similar to Perl's quotemeta function. It always returns a fresh
+string.
+
+Like APROPOS
+but searches for interned symbols which match the regular expression
+regex. The output is implementation-dependent. If
+case-insensitive is true (which is the default)
+and regex isn't already a scanner, a
+case-insensitive scanner is used.
+
+Like APROPOS-LIST
+but searches for interned symbols which match the regular expression
+regex. If case-insensitive is
+true (which is the default) and regex isn't
+already a scanner, a case-insensitive scanner is used.
+
+Errors of type PPCRE-INVOCATION-ERROR
+are signaled if one of the exported functions of CL-PPCRE is called with wrong or
+inconsistent arguments. This is a direct subtype of PPCRE-ERROR without any
+additional slots or options.
+
+An error of type PPCRE-SYNTAX-ERROR is signaled if
+CL-PPCRE's parser encounters an error when trying to parse a regex
+string or to convert a parse tree into its internal representation.
+This is a direct subtype of PPCRE-ERROR with two additional
+slots. These denote the regex string which HTML-PPCRE was parsing and
+the position within the string where the error occurred. If the error
+happens while CL-PPCRE is converting a parse tree, both of these slots
+contain NIL. (See the next two entries on how to access
+these slots.)
+
+As many syntax errors can't be detected before the parser is at the
+end of the stream, the row and column usually denote the last position
+where the parser was happy and not the position where it gave up.
+
+
+* (handler-case
+ (scan "foo**x" "fooox")
+ (ppcre-syntax-error (condition)
+ (format t "Houston, we've got a problem with the string ~S:~%~
+ Looks like something went wrong at position ~A.~%~
+ The last message we received was \"~?\"."
+ (ppcre-syntax-error-string condition)
+ (ppcre-syntax-error-pos condition)
+ (simple-condition-format-control condition)
+ (simple-condition-format-arguments condition))
+ (values)))
+Houston, we've got a problem with the string "foo**x":
+Looks like something went wrong at position 4.
+The last message we received was "Quantifier '*' not allowed.".
+
+If condition is a condition of type PPCRE-SYNTAX-ERROR, this
+function will return the string the parser was parsing when the error was
+encountered (or NIL if the error happened while trying to
+convert a parse tree). This might be particularly useful when *ALLOW-QUOTING* is
+true because in this case the offending string might not be the one you gave to the CREATE-SCANNER function.
+
+If condition is a condition of type PPCRE-SYNTAX-ERROR, this
+function will return the position within the string where the error
+occurred (or NIL if the error happened while trying to
+convert a parse tree).
+
+
+Because several users have asked for it, CL-PPCRE now offers
+"filters" (see above for syntax)
+which are basically arbitrary, user-defined functions that can act as
+regex building blocks. Filters can only be used within parse trees, not within Perl regex
+strings.
+
+A filter is defined by its filter function which must be a
+function of one argument. During the parsing process this function
+might be called once or several times or it might not be called at
+all. If it's called, its argument is an integer pos
+which is the current position within the target string. The filter can
+either return NIL (which means that the subexpression
+represented by this filter didn't match) or an integer not smaller
+than pos for success. A zero-length assertion
+should return pos itself while a filter which
+wants to consume N characters should return
+(+ POS N).
+
+If you supply the optional value length and it is
+not NIL, then this is a promise to the regex engine that
+your filter will always consume exactly
+length characters. The regex engine might use this
+information for optimization purposes but it is otherwise irrelevant
+to the outcome of the matching process.
+
+The filter function can access the following special variables from
+its code body:
+
+
+
CL-PPCRE::*STRING*
+
The target (a string) of the current matching process.
+
+
CL-PPCRE::*START-POS* and
+CL-PPCRE::*END-POS*
+
The start and end (integers) indices
+of the current matching process. These correspond to the
+START and END keyword parameters
+of SCAN.
+
+
CL-PPCRE::*REAL-START-POS*
+
The initial starting
+position. This is only relevant for repeated scans (as in DO-SCANS) where
+CL-PPCRE::*START-POS* will be moved forward while
+CL-PPCRE::*REAL-START-POS* won't. For normal scans the
+value of this variable is NIL.
+
+
CL-PPCRE::*REG-STARTS* and
+CL-PPCRE::*REG-ENDS*
+
Two simple vectors which denote the
+start and end indices of registers within the regular expression. The
+first register is indexed by 0. If a register hasn't matched yet,
+then its corresponding entry in CL-PPCRE::*REG-STARTS* is
+NIL.
+
+
+
+These variables should be considered read-only. Do not change
+these values unless you really know what you're doing!
+
+Note that the names of the variables are not exported from the
+CL-PPCRE package because there's no explicit guarantee
+that they will be available in future releases. (Although after so
+many years it is very unlikely that they'll go away...)
+
+* (defun my-info-filter (pos)
+ "Show some info about the matching process."
+ (format t "Called at position ~A~%" pos)

+
+
+Note that in the second call to SCAN our filter wasn't
+invoked at all - it was optimized away by the regex engine because it
+knew that it couldn't match. Also note that *WEIRD-REGEX*
+still worked after we removed the global function definition of
+MY-WEIRD-FILTER because the regular expression had
+captured the original definition.
+
+
+
+(Cf. case #1439 of perltestdata.)
+Well, OK, this ain't a Perl bug. I just can't quite understand why
+captured groups should only be seen within the scope of a look-ahead
+or look-behind. For the moment, CL-PPCRE and Perl agree to
+disagree... :)
+
+
+
+The names of Unicode properties are derived
+from CL-UNICODE and might
+differ slightly from the names in Perl. Most of them should be
+identical, though.
+Also, CL-UNICODE is based on
+Unicode 5.1 while your installed Perl version might be not.
+
+
+
+(Cf. case #9 of perltestdata.) For
+some strange reason that I don't understand MCL translates
+#\Return to (CODE-CHAR 10) while MacPerl
+translates "\r" to (CODE-CHAR
+13). Hmmm...
+
+
+
+CL-PPCRE uses ALPHANUMERICP
+to decide whether a character matches Perl's
+"\w", so depending on your CL implementation
+you might encounter differences between Perl and CL-PPCRE when
+matching non-ASCII characters.
+
+
+
+If you try to do something similar in CL-PPCRE, you get an error:
+
+
+* (let ((*allow-quoting* t)
+ (a "\\E*"))
+ (scan (concatenate 'string "(?:\\Q" a "\\E){2}") "\\E*\\E*"))
+Quantifier '*' not allowed at position 3 in string "(?:*\\E){2}"
+
+
+The error message might give you a hint as to why this happens:
+Because *ALLOW-QUOTING*
+was true the concatenated string was pre-processed before it
+was fed to CL-PPCRE's parser - the result of this pre-processing is
+"(?:*\\E){2}" because the
+"\\E" in the string A was taken to
+be the end of the quoted section started by
+"\\Q". This cannot happen in Perl due to its
+complicated interpolation rules - see man perlop for
+the scary details. It can happen in CL-PPCRE, though.
+Bummer!
+
+What gives? "\\Q...\\E" in CL-PPCRE should only
+be used in literal strings. If you want to quote arbitrary strings,
+try CL-INTERPOL or use QUOTE-META-CHARS:
+
+
+You didn't expect this to yield NIL, did you? Shouldn't something like (SCAN A A) always return a true value? No, because the first and the second argument to SCAN are handled differently: The first argument is fed to CL-PPCRE's parser and is treated like a Perl regular expression. In particular, the parser "sees" \y and converts it to y because \y has no special meaning in regular expressions. So, the regular expression is the constant string "yy". But the second argument isn't converted - it is left as is, i.e. it's equivalent to Perl's 'y\y'. In other words, this example would be equivalent to the Perl code
+
+
+'y\y' =~ /y\y/;
+
+
+or to
+
+
+$a = 'y\y';
+$a =~ /$a/;
+
+
+which should explain why it doesn't match.
+
+Still confused? You might want to try CL-INTERPOL.
+
+
+
+Since autumn 2004 AllegroCL offers
+a
+new regular expression API with a syntax very similar to
+CL-PPCRE. Although CL-PPCRE is quite fast already, AllegroCL's engine will
+most likely be even faster (but only on AllegroCL, of course). However, you might want to
+stick to CL-PPCRE because you have a "legacy" application or because
+you want your code to be portable to other Lisp implementations.
+Therefore, beginning from version 1.2.0, CL-PPCRE offers a
+"compatibility mode" where you can continue using the CL-PPCRE API as
+described above but deploy the AllegroCL regex
+engine under the hood. (The details are: Calls to CREATE-SCANNER and SCAN are dispatched to their AllegroCL
+counterparts EXCL:COMPILE-RE
+and EXCL:MATCH-RE
+while everything else is left as is.)
+
+The advantage of this mode is that you'll get a much smaller image and
+most likely faster code. (But note that CL-PPCRE needs to do a small amount of work to massage AllegroCL's output into the format expected by CL-PPCRE.) The downside is that your code won't be
+fully compatible with CL-PPCRE anymore. Here are some of the
+differences (most of which probably don't matter very often):
+
+
+Here are, in no particular order, a couple of things about CL-PPCRE
+and regular expressions in general that you might or might not want to
+read.
+
+
+
A lot of hackers (especially users of Perl and other scripting
+ languages) think that regular expressions are the greatest thing
+ since sliced bread and use it for almost everything. That is just
+ plain wrong. Other hackers (especially Lispers) tend to think that
+ regular expressions are the work of the devil and try to avoid them
+ at all cost. That's also wrong. Regular expressions are a handy
+ and useful addition to your toolkit which you should use when
+ appropriate - you should just try to figure out first if
+ they're appropriate for the task at hand.
+
+
If you're concerned about the string syntax of regular
+ expressions which can look like line noise and is really hard to
+ read for long expressions, consider using
+ CL-PPCRE's S-expression syntax
+ instead. It is less error-prone and you don't have to worry about
+ escaping characters. It is also easier to manipulate
+ programmatically.
+
+
For alternations, order is important. The general rule is that
+ the regex engine tries from left to right and tries to match as much
+ as possible.
+
CL-PPCRE
+ uses compiler
+ macros to pre-compile scanners
+ at load
+ time if possible. This happens if the compiler can determine
+ that the regular expression (no matter if it's a string or an
+ S-expression)
+ is constant
+ at compile
+ time and is intended to save the time for creating scanners
+ at execution
+ time (probably creating the same scanner over and over in a
+ loop). Make sure you don't prevent the compiler from helping you.
+ For example, a definition like this one is usually not a good idea:
+
If you want to search for a substring in a large string or if
+ you search for the same string very
+ often, SCAN will usually be faster
+ than Common
+ Lisp's SEARCH
+ if you use BMH matchers. However,
+ this only makes sense if scanner creation time is not the
+ limiting factor, i.e. if the search target is very large or
+ if you're using the same scanner very often.
+
+
Complementary to the last hint, don't use regular
+ expressions for one-time searches for constant strings. That's a
+ terrible waste of resources.
+
+
A character class is by default translated into a sequence of
+ tests exactly as you might expect. For
+ example, "[af-l\\d]" means to test if the character is
+ equal to #\a, then to test if it's
+ between #\f and #\l, then if it's a digit.
+ There's by default no attempt to remove redundancy (as
+ in "[a-ge-kf]") or to otherwise optimize these tests
+ for speed. However, you can play
+ with *OPTIMIZE-CHAR-CLASSES*
+ if you've identified character classes as a bottleneck and want to
+ make sure that you have O(1) test functions.
+
+
If you know that the expression you're looking for is anchored,
+ use anchors in your regex. This can help the engine a lot to make
+ your scanners more efficient.
+
+
In addition to anchors, constant strings at the start or end of a
+ regular expression can help the engine to quickly scan a string.
+ Note that for example "(a-d|aebf)"
+ and "ab(cd|ef)" are equivalent, but only the second
+ form has a constant start the regex engine can recognize.
+
+
Try to avoid alternations if possible or at least factor them
+ out as in the example above.
+
+
If neither anchors nor constant strings are in sight, maybe
+ "standalone" (sometimes also called "possessive") regular
+ expressions can be helpful. Try the following:
+
Consider using "single-line mode"
+ if it makes sense for your task. By default (following Perl's
+ practice), a dot means to search for any character except
+ line breaks. In single-line mode a dot searches for any
+ character which in some cases means that large parts of the target
+ can actually be skipped. This can be vastly more efficient for
+ large targets.
+
+
Don't use capturing register groups where a non-capturing group
+ would do, i.e. only use registers if you need to refer to
+ them later. If you use a register, each scan process needs to
+ allocate space for it and update its contents (possibly many times)
+ until it's finished. (In Perl parlance - use "(?:foo)" instead of
+ "(foo)" whenever possible.)
+
+
In addition to what has been said in the last hint, note that
+ Perl semantics force the regex engine to report the last
+ match for each register. This implies for example
+ that "([a-c])+" and "[a-c]*([a-c])" have
+ exactly the same semantics but completely different performance
+ characteristics. (Actually, in some cases CL-PPCRE automatically
+ converts expressions from the first type into the second type.
+ That's not always possible, though, and you shouldn't rely on it.)
+
+
By default, repetitions are "greedy" in Perl (and thus in
+ CL-PPCRE). This has an impact on performance and also on the actual
+ outcome of a scan. Look at your repetitions and ponder if a greedy
+ repetition is really what you want.
+
+
+Although I didn't use their code, I was heavily inspired by looking at
+the Scheme/CL regex implementations of Dorai
+Sitaram and Michael
+Parker. Also, the nice folks from CMUCL's mailing list as well
+as the output of Perl's use re "debug" pragma
+have been very helpful in optimizing the scanners created by CL-PPCRE.
+
+
The list of people who participated in this project in one way or
+the other has grown too long to maintain it here. See the ChangeLog

+ways. Thanks to all of them!
