Renamed the installed files to -avoid conflicts with other regex libraries. - -New in alpha3.8: Bug fix for signed/unsigned mixup, found and fixed -by the FreeBSD folks. - -New in alpha3.7: A bit of cleanup aimed at maximizing portability, -possibly at slight cost in efficiency. "ul" suffixes and "unsigned long" -no longer appear, in particular. - -New in alpha3.6: A couple more portability glitches fixed. - -New in alpha3.5: Active development of this code has been stopped -- -I'm working on a complete reimplementation -- but folks have found some -minor portability glitches and the like, hence this release to fix them. -One penalty: slightly reduced compatibility with old compilers, because -the ANSI C `unsigned long' type and `ul' constant suffix are used in a -few places (I could avoid this but it would be considerably more work). - -New in alpha3.4: The complex bug alluded to below has been fixed (in a -slightly kludgey temporary way that may hurt efficiency a bit; this is -another "get it out the door for 4.4" release). The tests at the end of -the tests file have accordingly been uncommented. The primary sign of -the bug was that something like a?b matching ab matched b rather than ab. -(The bug was essentially specific to this exact situation, else it would -have shown up earlier.) - -New in alpha3.3: The definition of word boundaries has been altered -slightly, to more closely match the usual programming notion that "_" -is an alphabetic. Stuff used for pre-ANSI systems is now in a subdir, -and the makefile no longer alludes to it in mysterious ways. The -makefile has generally been cleaned up some. Fixes have been made -(again!) so that the regression test will run without -DREDEBUG, at -the cost of weaker checking. A workaround for a bug in some folks' - has been added. And some more things have been added to -tests, including a couple right at the end which are commented out -because the code currently flunks them (complex bug; fix coming). -Plus the usual minor cleanup. - -New in alpha3.2: Assorted bits of cleanup and portability improvement -(the development base is now a BSDI system using GCC instead of an ancient -Sun system, and the newer compiler exposed some glitches). Fix for a -serious bug that affected REs using many [] (including REG_ICASE REs -because of the way they are implemented), *sometimes*, depending on -memory-allocation patterns. The header-file prototypes no longer name -the parameters, avoiding possible name conflicts. The possibility that -some clot has defined CHAR_MIN as (say) `-128' instead of `(-128)' is -now handled gracefully. "uchar" is no longer used as an internal type -name (too many people have the same idea). Still the same old lousy -performance, alas. - -New in alpha3.1: Basically nothing, this release is just a bookkeeping -convenience. Stay tuned. - -New in alpha3.0: Performance is no better, alas, but some fixes have been -made and some functionality has been added. (This is basically the "get -it out the door in time for 4.4" release.) One bug fix: regfree() didn't -free the main internal structure (how embarrassing). It is now possible -to put NULs in either the RE or the target string, using (resp.) a new -REG_PEND flag and the old REG_STARTEND flag. The REG_NOSPEC flag to -regcomp() makes all characters ordinary, so you can match a literal -string easily (this will become more useful when performance improves!). -There are now primitives to match beginnings and ends of words, although -the syntax is disgusting and so is the implementation. The REG_ATOI -debugging interface has changed a bit. And there has been considerable -internal cleanup of various kinds. - -New in alpha2.3: Split change list out of README, and moved flags notes -into Makefile. Macro-ized the name of regex(7) in regex(3), since it has -to change for 4.4BSD. Cleanup work in engine.c, and some new regression -tests to catch tricky cases thereof. - -New in alpha2.2: Out-of-date manpages updated. Regerror() acquires two -small extensions -- REG_ITOA and REG_ATOI -- which avoid debugging kludges -in my own test program and might be useful to others for similar purposes. -The regression test will now compile (and run) without REDEBUG. The -BRE \$ bug is fixed. Most uses of "uchar" are gone; it's all chars now. -Char/uchar parameters are now written int/unsigned, to avoid possible -portability problems with unpromoted parameters. Some unsigned casts have -been introduced to minimize portability problems with shifting into sign -bits. - -New in alpha2.1: Lots of little stuff, cleanup and fixes. The one big -thing is that regex.h is now generated, using mkh, rather than being -supplied in the distribution; due to circularities in dependencies, -you have to build regex.h explicitly by "make h". The two known bugs -have been fixed (and the regression test now checks for them), as has a -problem with assertions not being suppressed in the absence of REDEBUG. -No performance work yet. - -New in alpha2: Backslash-anything is an ordinary character, not an -error (except, of course, for the handful of backslashed metacharacters -in BREs), which should reduce script breakage. The regression test -checks *where* null strings are supposed to match, and has generally -been tightened up somewhat. Small bug fixes in parameter passing (not -harmful, but technically errors) and some other areas. Debugging -invoked by defining REDEBUG rather than not defining NDEBUG. - -New in alpha+3: full prototyping for internal routines, using a little -helper program, mkh, which extracts prototypes given in stylized comments. -More minor cleanup. Buglet fix: it's CHAR_BIT, not CHAR_BITS. Simple -pre-screening of input when a literal string is known to be part of the -RE; this does wonders for performance. - -New in alpha+2: minor bits of cleanup. Notably, the number "32" for the -word width isn't hardwired into regexec.c any more, the public header -file prototypes the functions if __STDC__ is defined, and some small typos -in the manpages have been fixed. - -New in alpha+1: improvements to the manual pages, and an important -extension, the REG_STARTEND option to regexec(). diff --git a/lib/rxspencer/autogen.sh b/lib/rxspencer/autogen.sh deleted file mode 100755 index 81835c10d..000000000 --- a/lib/rxspencer/autogen.sh +++ /dev/null @@ -1,5 +0,0 @@ -#!/bin/sh -libtoolize -c --automake --force -aclocal -autoconf -Wall --force -automake -Wall --add-missing --force-missing --copy diff --git a/lib/rxspencer/cclass.h b/lib/rxspencer/cclass.h deleted file mode 100644 index 0c293028e..000000000 --- a/lib/rxspencer/cclass.h +++ /dev/null @@ -1,31 +0,0 @@ -/* character-class table */ -static struct cclass { - char *name; - char *chars; - char *multis; -} cclasses[] = { - "alnum", "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz\ -0123456789", "", - "alpha", "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz", - "", - "blank", " \t", "", - "cntrl", "\007\b\t\n\v\f\r\1\2\3\4\5\6\16\17\20\21\22\23\24\ -\25\26\27\30\31\32\33\34\35\36\37\177", "", - "digit", "0123456789", "", - "graph", "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz\ -0123456789!\"#$%&'()*+,-./:;<=>?@[\\]^_`{|}~", - "", - "lower", "abcdefghijklmnopqrstuvwxyz", - "", - "print", "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz\ -0123456789!\"#$%&'()*+,-./:;<=>?@[\\]^_`{|}~ ", - "", - "punct", "!\"#$%&'()*+,-./:;<=>?@[\\]^_`{|}~", - "", - "space", "\t\n\v\f\r ", "", - "upper", "ABCDEFGHIJKLMNOPQRSTUVWXYZ", - "", - "xdigit", "0123456789ABCDEFabcdef", - "", - NULL, 0, "" -}; diff --git a/lib/rxspencer/cname.h b/lib/rxspencer/cname.h deleted file mode 100644 index 02e86e912..000000000 --- a/lib/rxspencer/cname.h +++ /dev/null @@ -1,102 +0,0 @@ -/* character-name table */ -static struct cname { - char *name; - char code; -} cnames[] = { - "NUL", '\0', - "SOH", '\001', - "STX", '\002', - "ETX", '\003', - "EOT", '\004', - "ENQ", '\005', - "ACK", '\006', - "BEL", '\007', - "alert", '\007', - "BS", '\010', - "backspace", '\b', - "HT", '\011', - "tab", '\t', - "LF", '\012', - "newline", '\n', - "VT", '\013', - "vertical-tab", '\v', - "FF", '\014', - "form-feed", '\f', - "CR", '\015', - "carriage-return", '\r', - "SO", '\016', - "SI", '\017', - "DLE", '\020', - "DC1", '\021', - "DC2", '\022', - "DC3", '\023', - "DC4", '\024', - "NAK", '\025', - "SYN", '\026', - "ETB", '\027', - "CAN", '\030', - "EM", '\031', - "SUB", '\032', - "ESC", '\033', - "IS4", '\034', - "FS", '\034', - "IS3", '\035', - "GS", '\035', - "IS2", '\036', - "RS", '\036', - "IS1", '\037', - "US", '\037', - "space", ' ', - "exclamation-mark", '!', - "quotation-mark", '"', - "number-sign", '#', - "dollar-sign", '$', - "percent-sign", '%', - "ampersand", '&', - "apostrophe", '\'', - "left-parenthesis", '(', - "right-parenthesis", ')', - "asterisk", '*', - "plus-sign", '+', - "comma", ',', - "hyphen", '-', - "hyphen-minus", '-', - "period", '.', - "full-stop", '.', - "slash", '/', - "solidus", '/', - "zero", '0', - "one", '1', - "two", '2', - "three", '3', - "four", '4', - "five", '5', - "six", '6', - "seven", '7', - "eight", '8', - "nine", '9', - "colon", ':', - "semicolon", ';', - "less-than-sign", '<', - "equals-sign", '=', - "greater-than-sign", '>', - "question-mark", '?', - "commercial-at", '@', - "left-square-bracket", '[', - "backslash", '\\', - "reverse-solidus", '\\', - "right-square-bracket", ']', - "circumflex", '^', - "circumflex-accent", '^', - "underscore", '_', - "low-line", '_', - "grave-accent", '`', - "left-brace", '{', - "left-curly-bracket", '{', - "vertical-line", '|', - "right-brace", '}', - "right-curly-bracket", '}', - "tilde", '~', - "DEL", '\177', - NULL, 0, -}; diff --git a/lib/rxspencer/compile b/lib/rxspencer/compile deleted file mode 100755 index a85b723c7..000000000 --- a/lib/rxspencer/compile +++ /dev/null @@ -1,347 +0,0 @@ -#! /bin/sh -# Wrapper for compilers which do not understand '-c -o'. - -scriptversion=2012-10-14.11; # UTC - -# Copyright (C) 1999-2014 Free Software Foundation, Inc. -# Written by Tom Tromey . -# -# This program is free software; you can redistribute it and/or modify -# it under the terms of the GNU General Public License as published by -# the Free Software Foundation; either version 2, or (at your option) -# any later version. -# -# This program is distributed in the hope that it will be useful, -# but WITHOUT ANY WARRANTY; without even the implied warranty of -# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

DESCRIPTION -These routines implement POSIX 1003.2 regular expressions (``RE''s); -see -.ZR . -.I Regcomp -compiles an RE written as a string into an internal form, -.I regexec -matches that internal form against a string and reports results, -.I regerror -transforms error codes from either into human-readable messages, -and -.I regfree -frees any dynamically-allocated storage used by the internal form -of an RE. -.PP -The header -.I -declares two structure types, -.I regex_t -and -.IR regmatch_t , -the former for compiled internal forms and the latter for match reporting. -It also declares the four functions, -a type -.IR regoff_t , -and a number of constants with names starting with ``REG_''. -.PP -.I Regcomp -compiles the regular expression contained in the -.I pattern -string, -subject to the flags in -.IR cflags , -and places the results in the -.I regex_t -structure pointed to by -.IR preg . -.I Cflags -is the bitwise OR of zero or more of the following flags: -.IP REG_EXTENDED \w'REG_EXTENDED'u+2n -Compile modern (``extended'') REs, -rather than the obsolete (``basic'') REs that -are the default. -.IP REG_BASIC -This is a synonym for 0, -provided as a counterpart to REG_EXTENDED to improve readability. -This is an extension, -compatible with but not specified by POSIX 1003.2, -and should be used with -caution in software intended to be portable to other systems. -.IP REG_NOSPEC -Compile with recognition of all special characters turned off. -All characters are thus considered ordinary, -so the ``RE'' is a literal string. -This is an extension, -compatible with but not specified by POSIX 1003.2, -and should be used with -caution in software intended to be portable to other systems. -REG_EXTENDED and REG_NOSPEC may not be used -in the same call to -.IR regcomp . -.IP REG_ICASE -Compile for matching that ignores upper/lower case distinctions. -See -.ZR . -.IP REG_NOSUB -Compile for matching that need only report success or failure, -not what was matched. -.IP REG_NEWLINE -Compile for newline-sensitive matching. -By default, newline is a completely ordinary character with no special -meaning in either REs or strings. -With this flag, -`[^' bracket expressions and `.' never match newline, -a `^' anchor matches the null string after any newline in the string -in addition to its normal function, -and the `$' anchor matches the null string before any newline in the -string in addition to its normal function. -.IP REG_PEND -The regular expression ends, -not at the first NUL, -but just before the character pointed to by the -.I re_endp -member of the structure pointed to by -.IR preg . -The -.I re_endp -member is of type -.IR const\ char\ * . -This flag permits inclusion of NULs in the RE; -they are considered ordinary characters. -This is an extension, -compatible with but not specified by POSIX 1003.2, -and should be used with -caution in software intended to be portable to other systems. -.PP -When successful, -.I regcomp -returns 0 and fills in the structure pointed to by -.IR preg . -One member of that structure -(other than -.IR re_endp ) -is publicized: -.IR re_nsub , -of type -.IR size_t , -contains the number of parenthesized subexpressions within the RE -(except that the value of this member is undefined if the -REG_NOSUB flag was used). -If -.I regcomp -fails, it returns a non-zero error code; -see DIAGNOSTICS. -.PP -.I Regexec -matches the compiled RE pointed to by -.I preg -against the -.IR string , -subject to the flags in -.IR eflags , -and reports results using -.IR nmatch , -.IR pmatch , -and the returned value. -The RE must have been compiled by a previous invocation of -.IR regcomp . -The compiled form is not altered during execution of -.IR regexec , -so a single compiled RE can be used simultaneously by multiple threads. -.PP -By default, -the NUL-terminated string pointed to by -.I string -is considered to be the text of an entire line, -with the NUL indicating the end of the line. -(That is, -any other end-of-line marker is considered to have been removed -and replaced by the NUL.) -The -.I eflags -argument is the bitwise OR of zero or more of the following flags: -.IP REG_NOTBOL \w'REG_STARTEND'u+2n -The first character of -the string -is not the beginning of a line, so the `^' anchor should not match before it. -This does not affect the behavior of newlines under REG_NEWLINE. -.IP REG_NOTEOL -The NUL terminating -the string -does not end a line, so the `$' anchor should not match before it. -This does not affect the behavior of newlines under REG_NEWLINE. -.IP REG_STARTEND -The string is considered to start at -\fIstring\fR\ + \fIpmatch\fR[0].\fIrm_so\fR -and to have a terminating NUL located at -\fIstring\fR\ + \fIpmatch\fR[0].\fIrm_eo\fR -(there need not actually be a NUL at that location), -regardless of the value of -.IR nmatch . -See below for the definition of -.IR pmatch -and -.IR nmatch . -This is an extension, -compatible with but not specified by POSIX 1003.2, -and should be used with -caution in software intended to be portable to other systems. -Note that a non-zero \fIrm_so\fR does not imply REG_NOTBOL; -REG_STARTEND affects only the location of the string, -not how it is matched. -.PP -See -.ZR -for a discussion of what is matched in situations where an RE or a -portion thereof could match any of several substrings of -.IR string . -.PP -Normally, -.I regexec -returns 0 for success and the non-zero code REG_NOMATCH for failure. -Other non-zero error codes may be returned in exceptional situations; -see DIAGNOSTICS. -.PP -If REG_NOSUB was specified in the compilation of the RE, -or if -.I nmatch -is 0, -.I regexec -ignores the -.I pmatch -argument (but see below for the case where REG_STARTEND is specified). -Otherwise, -.I pmatch -points to an array of -.I nmatch -structures of type -.IR regmatch_t . -Such a structure has at least the members -.I rm_so -and -.IR rm_eo , -both of type -.I regoff_t -(a signed arithmetic type at least as large as an -.I off_t -and a -.IR ssize_t ), -containing respectively the offset of the first character of a substring -and the offset of the first character after the end of the substring. -Offsets are measured from the beginning of the -.I string -argument given to -.IR regexec . -An empty substring is denoted by equal offsets, -both indicating the character following the empty substring. -.PP -The 0th member of the -.I pmatch -array is filled in to indicate what substring of -.I string -was matched by the entire RE. -Remaining members report what substring was matched by parenthesized -subexpressions within the RE; -member -.I i -reports subexpression -.IR i , -with subexpressions counted (starting at 1) by the order of their opening -parentheses in the RE, left to right. -Unused entries in the array\(emcorresponding either to subexpressions that -did not participate in the match at all, or to subexpressions that do not -exist in the RE (that is, \fIi\fR\ > \fIpreg\fR\->\fIre_nsub\fR)\(emhave both -.I rm_so -and -.I rm_eo -set to \-1. -If a subexpression participated in the match several times, -the reported substring is the last one it matched. -(Note, as an example in particular, that when the RE `(b*)+' matches `bbb', -the parenthesized subexpression matches the three `b's and then -an infinite number of empty strings following the last `b', -so the reported substring is one of the empties.) -.PP -If REG_STARTEND is specified, -.I pmatch -must point to at least one -.I regmatch_t -(even if -.I nmatch -is 0 or REG_NOSUB was specified), -to hold the input offsets for REG_STARTEND. -Use for output is still entirely controlled by -.IR nmatch ; -if -.I nmatch -is 0 or REG_NOSUB was specified, -the value of -.IR pmatch [0] -will not be changed by a successful -.IR regexec . -.PP -.I Regerror -maps a non-zero -.I errcode -from either -.I regcomp -or -.I regexec -to a human-readable, printable message. -If -.I preg -is non-NULL, -the error code should have arisen from use of -the -.I regex_t -pointed to by -.IR preg , -and if the error code came from -.IR regcomp , -it should have been the result from the most recent -.I regcomp -using that -.IR regex_t . -.RI ( Regerror -may be able to supply a more detailed message using information -from the -.IR regex_t .) -.I Regerror -places the NUL-terminated message into the buffer pointed to by -.IR errbuf , -limiting the length (including the NUL) to at most -.I errbuf_size -bytes. -If the whole message won't fit, -as much of it as will fit before the terminating NUL is supplied. -In any case, -the returned value is the size of buffer needed to hold the whole -message (including terminating NUL). -If -.I errbuf_size -is 0, -.I errbuf -is ignored but the return value is still correct. -.PP -If the -.I errcode -given to -.I regerror -is first ORed with REG_ITOA, -the ``message'' that results is the printable name of the error code, -e.g. ``REG_NOMATCH'', -rather than an explanation thereof. -If -.I errcode -is REG_ATOI, -then -.I preg -shall be non-NULL and the -.I re_endp -member of the structure it points to -must point to the printable name of an error code; -in this case, the result in -.I errbuf -is the decimal digits of -the numeric value of the error code -(0 if the name is not recognized). -REG_ITOA and REG_ATOI are intended primarily as debugging facilities; -they are extensions, -compatible with but not specified by POSIX 1003.2, -and should be used with -caution in software intended to be portable to other systems. -Be warned also that they are considered experimental and changes are possible. -.PP -.I Regfree -frees any dynamically-allocated storage associated with the compiled RE -pointed to by -.IR preg . -The remaining -.I regex_t -is no longer a valid compiled RE -and the effect of supplying it to -.I regexec -or -.I regerror -is undefined. -.PP -None of these functions references global variables except for tables -of constants; -all are safe for use from multiple threads if the arguments are safe. -.SH IMPLEMENTATION CHOICES -There are a number of decisions that 1003.2 leaves up to the implementor, -either by explicitly saying ``undefined'' or by virtue of them being -forbidden by the RE grammar. -This implementation treats them as follows. -.PP -See -.ZR -for a discussion of the definition of case-independent matching. -.PP -There is no particular limit on the length of REs, -except insofar as memory is limited. -Memory usage is approximately linear in RE size, and largely insensitive -to RE complexity, except for bounded repetitions. -See BUGS for one short RE using them -that will run almost any system out of memory. -.PP -A backslashed character other than one specifically given a magic meaning -by 1003.2 (such magic meanings occur only in obsolete [``basic''] REs) -is taken as an ordinary character. -.PP -Any unmatched [ is a REG_EBRACK error. -.PP -Equivalence classes cannot begin or end bracket-expression ranges. -The endpoint of one range cannot begin another. -.PP -RE_DUP_MAX, the limit on repetition counts in bounded repetitions, is 255. -.PP -A repetition operator (?, *, +, or bounds) cannot follow another -repetition operator. -A repetition operator cannot begin an expression or subexpression -or follow `^' or `|'. -.PP -`|' cannot appear first or last in a (sub)expression or after another `|', -i.e. an operand of `|' cannot be an empty subexpression. -An empty parenthesized subexpression, `()', is legal and matches an -empty (sub)string. -An empty string is not a legal RE. -.PP -A `{' followed by a digit is considered the beginning of bounds for a -bounded repetition, which must then follow the syntax for bounds. -A `{' \fInot\fR followed by a digit is considered an ordinary character. -.PP -`^' and `$' beginning and ending subexpressions in obsolete (``basic'') -REs are anchors, not ordinary characters. -.SH SEE

-henry@zoo.toronto.edu. -.SH BUGS -This is an alpha release with known defects. -Please report problems. -.PP -There is one known functionality bug. -The implementation of internationalization is incomplete: -the locale is always assumed to be the default one of 1003.2, -and only the collating elements etc. of that locale are available. -.PP -The back-reference code is subtle and doubts linger about its correctness -in complex cases. -.PP -.I Regexec -performance is poor. -This will improve with later releases. -.I Nmatch -exceeding 0 is expensive; -.I nmatch -exceeding 1 is worse. -.I Regexec -is largely insensitive to RE complexity \fIexcept\fR that back -references are massively expensive. -RE length does matter; in particular, there is a strong speed bonus -for keeping RE length under about 30 characters, -with most special characters counting roughly double. -.PP -.I Regcomp -implements bounded repetitions by macro expansion, -which is costly in time and space if counts are large -or bounded repetitions are nested. -An RE like, say, -`((((a{1,100}){1,100}){1,100}){1,100}){1,100}' -will (eventually) run almost any existing machine out of swap space. -.PP -There are suspected problems with response to obscure error conditions. -Notably, -certain kinds of internal overflow, -produced only by truly enormous REs or by multiply nested bounded repetitions, -are probably not handled well. -.PP -Due to a mistake in 1003.2, things like `a)b' are legal REs because `)' is -a special character only in the presence of a previous unmatched `('. -This can't be fixed until the spec is fixed. -.PP -The standard's definition of back references is vague. -For example, does -`a\e(\e(b\e)*\e2\e)*d' match `abbbd'? -Until the standard is clarified, -behavior in such cases should not be relied on. -.PP -The implementation of word-boundary matching is a bit of a kludge, -and bugs may lurk in combinations of word-boundary matching and anchoring. diff --git

bound\(dg. -It is illegal to end an RE with `\e'. -.PP -A \fIbracket expression\fR is a list of characters enclosed in `[]'. -It normally matches any single character from the list (but see below). -If the list begins with `^', -it matches any single character -(but see below) \fInot\fR from the rest of the list. -If two characters in the list are separated by `\-', this is shorthand -for the full \fIrange\fR of characters between those two (inclusive) in the -collating sequence, -e.g. `[0\-9]' in ASCII matches any decimal digit. -It is illegal\(dg for two ranges to share an -endpoint, e.g. `a\-c\-e'. -Ranges are very collating-sequence-dependent, -and portable programs should avoid relying on them. -.PP -To include a literal `]' in the list, make it the first character -(following a possible `^'). -To include a literal `\-', make it the first or last character, -or the second endpoint of a range. -To use a literal `\-' as the first endpoint of a range, -enclose it in `[.' and `.]' to make it a collating element (see below). -With the exception of these and some combinations using `[' (see next -paragraphs), all other special characters, including `\e', lose their -special significance within a bracket expression. -.PP -Within a bracket expression, a collating element (a character, -a multi-character sequence that collates as if it were a single character, -or a collating-sequence name for either) -enclosed in `[.' and `.]' stands for the -sequence of characters of that collating element. -The sequence is a single element of the bracket expression's list. -A bracket expression containing a multi-character collating element -can thus match more than one character, -e.g. if the collating sequence includes a `ch' collating element, -then the RE `[[.ch.]]*c' matches the first five characters -of `chchcc'. -.PP -Within a bracket expression, a collating element enclosed in `[=' and -`=]' is an equivalence class, standing for the sequences of characters -of all collating elements equivalent to that one, including itself. -(If there are no other equivalent collating elements, -the treatment is as if the enclosing delimiters were `[.' and `.]'.) -For example, if o and \o'o^' are the members of an equivalence class, -then `[[=o=]]', `[[=\o'o^'=]]', and `[o\o'o^']' are all synonymous. -An equivalence class may not\(dg be an endpoint -of a range. -.PP -Within a bracket expression, the name of a \fIcharacter class\fR enclosed -in `[:' and `:]' stands for the list of all characters belonging to that -class. -Standard character class names are: -.PP -.RS -.nf -.ta 3c 6c 9c -alnum digit punct -alpha graph space -blank lower upper -cntrl print xdigit -.fi -.RE -.PP -These stand for the character classes defined in -.IR ctype (3). -A locale may provide others. -A character class may not be used as an endpoint of a range. -.PP -There are two special cases\(dg of bracket expressions: -the bracket expressions `[[:<:]]' and `[[:>:]]' match the null string at -the beginning and end of a word respectively. -A word is defined as a sequence of -word characters -which is neither preceded nor followed by -word characters. -A word character is an -.I alnum -character (as defined by -.IR ctype (3)) -or an underscore. -This is an extension, -compatible with but not specified by POSIX 1003.2, -and should be used with -caution in software intended to be portable to other systems. -.PP -In the event that an RE could match more than one substring of a given -string, -the RE matches the one starting earliest in the string. -If the RE could match more than one substring starting at that point, -it matches the longest. -Subexpressions also match the longest possible substrings, subject to -the constraint that the whole match be as long as possible, -with subexpressions starting earlier in the RE taking priority over -ones starting later. -Note that higher-level subexpressions thus take priority over -their lower-level component subexpressions. -.PP -Match lengths are measured in characters, not collating elements. -A null string is considered longer than no match at all. -For example, -`bb*' matches the three middle characters of `abbbc', -`(wee|week)(knights|nights)' matches all ten characters of `weeknights', -when `(.*).*' is matched against `abc' the parenthesized subexpression -matches all three characters, and -when `(a*)*' is matched against `bc' both the whole RE and the parenthesized -subexpression match the null string. -.PP -If case-independent matching is specified, -the effect is much as if all case distinctions had vanished from the -alphabet. -When an alphabetic that exists in multiple cases appears as an -ordinary character outside a bracket expression, it is effectively -transformed into a bracket expression containing both cases, -e.g. `x' becomes `[xX]'. -When it appears inside a bracket expression, all case counterparts -of it are added to the bracket expression, so that (e.g.) `[x]' -becomes `[xX]' and `[^x]' becomes `[^xX]'. -.PP -No particular limit is imposed on the length of REs\(dg. -Programs intended to be portable should not employ REs longer -than 256 bytes, -as an implementation can refuse to accept such REs and remain -POSIX-compliant. -.PP -Obsolete (``basic'') regular expressions differ in several respects. -`|', `+', and `?' are ordinary characters and there is no equivalent -for their functionality. -The delimiters for bounds are `\e{' and `\e}', -with `{' and `}' by themselves ordinary characters. -The parentheses for nested subexpressions are `\e(' and `\e)', -with `(' and `)' by themselves ordinary characters. -`^' is an ordinary character except at the beginning of the -RE or\(dg the beginning of a parenthesized subexpression, -`$' is an ordinary character except at the end of the -RE or\(dg the end of a parenthesized subexpression, -and `*' is an ordinary character if it appears at the beginning of the -RE or the beginning of a parenthesized subexpression -(after a possible leading `^'). -Finally, there is one new type of atom, a \fIback reference\fR: -`\e' followed by a non-zero decimal digit \fId\fR -matches the same sequence of characters -matched by the \fId\fRth parenthesized subexpression -(numbering subexpressions by the positions of their opening parentheses, -left to right), -so that (e.g.) `\e([bc]\e)\e1' matches `bb' or `cc' but not `bc'. -.SH SEE ALSO -rxspencer(3) -.PP -POSIX 1003.2, section 2.8 (Regular Expression Notation). -.SH HISTORY -Written by Henry Spencer, based on the 1003.2 spec. -.SH BUGS -Having two kinds of REs is a botch. -.PP -The current 1003.2 spec says that `)' is an ordinary character in -the absence of an unmatched `('; -this was an unintentional result of a wording error, -and change is likely. -Avoid relying on it. -.PP -Back references are a dreadful botch, -posing major problems for efficient implementations. -They are also somewhat vaguely defined -(does -`a\e(\e(b\e)*\e2\e)*d' match `abbbd'?). -Avoid using them. -.PP -1003.2's specification of case-independent matching is vague. -The ``one case implies all cases'' definition given above -is current consensus among implementors as to the right interpretation. -.PP -The syntax for word boundaries is incredibly ugly. diff --git a/lib/rxspencer/split.c b/lib/rxspencer/split.c deleted file mode
