This implementation adds -a third flavor, \fIadvanced\fR REs (``AREs''), basically EREs with -some significant extensions. -.PP -This manual page primarily describes AREs. BREs mostly exist for -backward compatibility in some old programs; they will be discussed at -the end. POSIX EREs are almost an exact subset of AREs. Features of -AREs that are not present in EREs will be indicated. - -.SH "REGULAR EXPRESSION SYNTAX" -.PP -Tcl regular expressions are implemented using the package written by -Henry Spencer, based on the 1003.2 spec and some (not quite all) of -the Perl5 extensions (thanks, Henry!).

matches the empty string. -.PP -A quantified atom is an \fIatom\fR possibly followed -by a single \fIquantifier\fR. -Without a quantifier, it matches a match for the atom. -The quantifiers, -and what a so-quantified atom matches, are: -.RS 2 -.TP 6 -\fB*\fR -a sequence of 0 or more matches of the atom -.TP -\fB+\fR -a sequence of 1 or more matches of the atom -.TP -\fB?\fR -a sequence of 0 or 1

below) \fInot\fR from the rest of the list. -.PP -If two characters in the list are separated by `\fB\-\fR', -this is shorthand -for the full \fIrange\fR of characters between those two (inclusive) in the -collating sequence, -e.g. -\fB[0\-9]\fR -in ASCII matches any decimal digit. -Two ranges may not share an -endpoint, so e.g. -\fBa\-c\-e\fR -is illegal. -Ranges are very collating-sequence-dependent, -and portable programs should avoid relying on them. -.PP -To include a literal -\fB]\fR -or -\fB\-\fR -in the list, -the simplest method is to -enclose it in -\fB[.\fR

with `\fB\e\fR'. -With the exception of these, some combinations using -\fB[\fR -(see next -paragraphs), and escapes, -all other special characters lose their -special significance within a bracket

collating elements even if none of them -appear in the bracket expression! -(\fINote:\fR Tcl currently has no multi-character collating elements. -This information is only for illustration.) -.PP -For example, assume the collating sequence includes a \fBch\fR -multi-character collating element. -Then the RE \fB[[.ch.]]*c\fR (zero or more \fBch\fP's followed by \fBc\fP) -matches the first five characters of `\fBchchcc\fR'. -Also, the RE \fB[^c]b\fR matches all of `\fBchb\fR' -(because \fB[^c]\fR matches the multi-character \fBch\fR). -.VE 8.2 -.PP -Within a bracket expression, a collating element enclosed in -\fB[=\fR -and -\fB=]\fR -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 `\fB[.\fR'\& -and `\fB.]\fR'.) -For example, if -\fBo\fR -and -\fB\o'o^'\fR -are the members of an equivalence class, -then `\fB[[=o=]]\fR', `\fB[[=\o'o^'=]]\fR', -and `\fB[o\o'o^']\fR'\& -are all synonymous. -An equivalence class may not be an endpoint -of a range. -.VS 8.2 -(\fINote:\fR -Tcl

-.TP -\fB\e\fImnn\fR -(where -\fIm\fR -is a nonzero digit, and -\fInn\fR -is some more digits, -and the decimal value -\fImnn\fR -is not greater than the number of closing capturing parentheses seen

expressions. -.PP -A back reference (AREs only) matches the same string matched by the parenthesized -subexpression specified by the number, -so that (e.g.) -\fB([bc])\e1\fR -matches -\fBbb\fR -or -\fBcc\fR -but not `\fBbc\fR'. -The subexpression must entirely precede the back reference in the RE. -Subexpressions are numbered in the order of their leading parentheses. -Non-capturing parentheses do not define subexpressions. -.PP -There is an inherent historical ambiguity between octal character-entry -escapes and back references, which is resolved by heuristics, -as hinted at above. -A leading zero always indicates an octal escape. -A single non-zero digit, not followed by another digit, -is always taken as a back reference. -A multi-digit sequence not starting with a zero is taken as a back -reference if it comes after a suitable subexpression -(i.e. the number is in the legal range for a back reference), -and otherwise is taken as octal. -.SH "METASYNTAX" -In addition to the main syntax described above, there are some special -forms and miscellaneous syntactic facilities available. -.PP -Normally the flavor of RE being used is specified by -application-dependent means. -However, this can be overridden by a \fIdirector\fR. -If an RE of any flavor begins with `\fB***:\fR', -the rest of the RE is an ARE. -If an RE of any flavor begins with `\fB***=\fR', -the rest of the RE is taken to be a literal string, -with all characters considered ordinary characters. -.PP -An ARE may begin with \fIembedded options\fR: -a sequence -\fB(?\fIxyz\fB)\fR -(where -\fIxyz\fR -is one or more alphabetic characters) -specifies options affecting the rest of the RE. -These supplement, and can override, -any options specified by the application. -The available option letters are: -.RS 2 -.TP 3 -\fBb\fR -rest of RE is a BRE -.TP 3 -\fBc\fR -case-sensitive matching (usual default) -.TP 3 -\fBe\fR -rest of RE is an ERE -.TP 3 -\fBi\fR -case-insensitive matching (see MATCHING, below) -.TP 3 -\fBm\fR -historical synonym for -\fBn\fR -.TP 3 -\fBn\fR -newline-sensitive matching (see MATCHING, below) -.TP 3 -\fBp\fR -partial newline-sensitive matching (see MATCHING, below) -.TP 3 -\fBq\fR -rest of RE is a literal (``quoted'') string, all ordinary characters -.TP 3 -\fBs\fR -non-newline-sensitive matching (usual default) -.TP 3 -\fBt\fR -tight syntax (usual default; see below) -.TP 3 -\fBw\fR -inverse partial newline-sensitive (``weird'') matching (see MATCHING, below) -.TP 3 -\fBx\fR -expanded syntax (see below) -.RE -.PP -Embedded options take effect at the -\fB)\fR -terminating the sequence. -They are available only at the start of an ARE, -and may not be used later within it. -.PP -In addition to the usual (\fItight\fR) RE syntax, in which all characters are -significant, there is an \fIexpanded\fR syntax, -available in all flavors of RE -with the \fB-expanded\fR switch, or in AREs with the embedded x option. -In the expanded syntax, -white-space characters are ignored -and all characters between a -\fB#\fR -and the following newline (or the end of the RE) are ignored, -permitting paragraphing and commenting a complex RE. -There are three exceptions to that basic rule: -.RS 2 -.PP -a white-space character or `\fB#\fR' preceded by `\fB\e\fR' is retained -.PP -white space or `\fB#\fR' within a bracket expression is retained -.PP -white space and comments are illegal within multi-character symbols -like the ARE `\fB(?:\fR' or the BRE `\fB\e(\fR' -.RE -.PP -Expanded-syntax white-space characters are blank, tab, newline, and -.VS 8.2 -any character that belongs to the \fIspace\fR character class. -.VE 8.2 -.PP -Finally, in an ARE, -outside bracket expressions, the sequence `\fB(?#\fIttt\fB)\fR' -(where -\fIttt\fR -is any text not containing a `\fB)\fR') -is a comment, -completely ignored. -Again, this is not allowed between the characters of -multi-character symbols like `\fB(?:\fR'. -Such comments are more a historical artifact than a useful facility, -and their use is deprecated; -use the expanded syntax instead. -.PP -\fINone\fR of these metasyntax extensions is available if the application -(or an initial -\fB***=\fR -director) -has specified that the user's input be treated as a literal string -rather than as an RE. -.SH MATCHING -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, -its choice is determined by its \fIpreference\fR: -either the longest substring, or the shortest. -.PP -Most atoms, and all constraints, have no preference. -A parenthesized RE has the same preference (possibly none) as the RE. -A quantified atom with quantifier -\fB{\fIm\fB}\fR -or -\fB{\fIm\fB}?\fR -has the same preference (possibly none) as the atom itself. -A quantified atom with other normal quantifiers (including -\fB{\fIm\fB,\fIn\fB}\fR -with -\fIm\fR -equal to -\fIn\fR) -prefers longest match. -A quantified atom with other non-greedy quantifiers (including -\fB{\fIm\fB,\fIn\fB}?\fR -with -\fIm\fR -equal to -\fIn\fR) -prefers shortest match. -A branch has the same preference as the first quantified atom in it -which has a preference. -An RE consisting of two or more branches connected by the -\fB|\fR -operator prefers longest match. -.PP -Subject to the constraints imposed by the rules for matching the whole RE, -subexpressions also match the longest or shortest possible substrings, -based on their preferences, -with subexpressions starting earlier in the RE taking priority over -ones starting later. -Note that outer subexpressions thus take priority over -their component subexpressions. -.PP -Note that the quantifiers -\fB{1,1}\fR -and -\fB{1,1}?\fR -can be used to force longest and shortest preference, respectively, -on a subexpression or a whole RE. -.PP -Match lengths are measured in characters, not collating elements. -An empty string is considered longer than no match at all. -For example, -\fBbb*\fR -matches the three middle characters of `\fBabbbc\fR', -\fB(week|wee)(night|knights)\fR -matches all ten characters of `\fBweeknights\fR', -when -\fB(.*).*\fR -is matched against -\fBabc\fR -the parenthesized subexpression -matches all three characters, and -when -\fB(a*)*\fR -is matched against -\fBbc\fR -both the whole RE and the parenthesized -subexpression match an empty 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, -so that -\fBx\fR -becomes `\fB[xX]\fR'. -When it appears inside a bracket expression, all case counterparts -of it are added to the bracket expression, so that -\fB[x]\fR -becomes -\fB[xX]\fR -and -\fB[^x]\fR -becomes `\fB[^xX]\fR'. -.PP -If newline-sensitive matching is specified, \fB.\fR -and bracket expressions using -\fB^\fR -will never match the newline character -(so that matches will never cross newlines unless the RE -explicitly arranges it) -and -\fB^\fR -and -\fB$\fR -will match the empty string after and before a newline -respectively, in addition to matching at beginning and end of string -respectively. -ARE -\fB\eA\fR -and -\fB\eZ\fR -continue to match beginning or end of string \fIonly\fR. -.PP -If partial newline-sensitive matching is specified, -this affects \fB.\fR -and bracket expressions -as with newline-sensitive matching, but not -\fB^\fR -and `\fB$\fR'. -.PP -If inverse partial newline-sensitive matching is specified, -this affects -\fB^\fR -and -\fB$\fR -as with -newline-sensitive matching, -but not \fB.\fR -and bracket expressions. -This isn't very useful but is provided for symmetry. -.SH "LIMITS AND COMPATIBILITY" -No particular limit is imposed on the length of REs. -Programs intended to be highly portable should not employ REs longer -than 256 bytes, -as a POSIX-compliant implementation can refuse to accept such REs. -.PP -The only feature of AREs that is actually incompatible with -POSIX EREs is that -\fB\e\fR -does not lose its special -significance inside bracket expressions. -All other ARE features use syntax which is illegal or has -undefined or unspecified effects in POSIX EREs; -the -\fB***\fR -syntax of directors likewise is outside the POSIX -syntax for both BREs and EREs. -.PP -Many of the ARE extensions are borrowed from Perl, but some have -been changed to clean them up, and a few Perl extensions are not present. -Incompatibilities of note include `\fB\eb\fR', `\fB\eB\fR', -the lack of special treatment for a trailing newline, -the addition of complemented bracket expressions to the things -affected by newline-sensitive matching, -the restrictions on parentheses and back references in lookahead constraints, -and the longest/shortest-match (rather than first-match) matching semantics. -.PP -The matching rules for REs containing both normal and non-greedy quantifiers -have changed since early beta-test versions of this package. -(The new rules are much simpler and cleaner, -but don't work as hard at guessing the user's real intentions.) -.PP -Henry Spencer's original 1986 \fIregexp\fR package, -still in widespread use (e.g., in pre-8.1 releases of Tcl), -implemented an early version of today's EREs. -There are four incompatibilities between \fIregexp\fR's near-EREs -(`RREs' for short) and AREs. -In roughly increasing order of significance: -.PP -.RS -In AREs, -\fB\e\fR -followed by an alphanumeric character is either an -escape or an error, -while in RREs, it was just another way of writing the -alphanumeric. -This should not be a problem because there was no reason to write -such a sequence in RREs. -.PP -\fB{\fR -followed by a digit in an ARE is the beginning of a bound, -while in RREs, -\fB{\fR -was always an ordinary character. -Such sequences should be rare, -and will often result in an error because following characters -will not look like a valid bound. -.PP -In AREs, -\fB\e\fR -remains a special character within `\fB[\|]\fR', -so a literal -\fB\e\fR -within -\fB[\|]\fR -must be written `\fB\e\e\fR'. -\fB\e\e\fR -also gives a literal -\fB\e\fR -within -\fB[\|]\fR -in RREs, -but only truly paranoid programmers routinely doubled the backslash. -.PP -AREs report the longest/shortest match for the RE, -rather than the first found in a specified search order. -This may affect some RREs which were written in the expectation that -the first match would be reported. -(The careful crafting of RREs to optimize the search order for fast -matching is obsolete (AREs examine all possible matches -in parallel, and their performance is largely insensitive to their -complexity) but cases where the search order was exploited to deliberately -find a match which was \fInot\fR the longest/shortest will need rewriting.) -.RE - -.SH "BASIC REGULAR EXPRESSIONS" -BREs differ from EREs in several respects. `\fB|\fR', `\fB+\fR', -and -\fB?\fR -are ordinary characters and there is no equivalent -for their functionality. -The delimiters for bounds are -\fB\e{\fR -and `\fB\e}\fR', -with -\fB{\fR -and -\fB}\fR -by themselves ordinary characters. -The parentheses for nested subexpressions are -\fB\e(\fR -and `\fB\e)\fR', -with -\fB(\fR -and -\fB)\fR -by themselves ordinary characters. -\fB^\fR -is an ordinary character except at the beginning of the -RE or the beginning of a parenthesized subexpression, -\fB$\fR -is an ordinary character except at the end of the -RE or the end of a parenthesized subexpression, -and -\fB*\fR -is an ordinary character if it appears at the beginning of the -RE or the beginning of a parenthesized subexpression -(after a possible leading `\fB^\fR'). -Finally, -single-digit back references are available, -and -\fB\e<\fR -and -\fB\e>\fR -are synonyms for -\fB[[:<:]]\fR -and -\fB[[:>:]]\fR -respectively; -no other escapes are available. - -.SH "SEE ALSO" -RegExp(3), regexp(n), regsub(n),

Spencer" +.SH NAME +regex \- POSIX 1003.2 regular expressions +.SH DESCRIPTION +Regular expressions (``RE''s), +as defined in POSIX 1003.2, come in two forms: +modern REs (roughly those of +.IR egrep ; +1003.2 calls these ``extended'' REs) +and obsolete REs (roughly those of +.IR ed ; +1003.2 ``basic'' REs). +Obsolete REs mostly exist for backward compatibility in some old programs; +they will be discussed at the end. +1003.2 leaves some aspects of RE syntax and semantics open; +`\(dg' marks decisions on these aspects that +may not be fully portable to other 1003.2 implementations. +.PP +A (modern) RE is one\(dg or more non-empty\(dg \fIbranches\fR, +separated by `|'. +It matches anything that matches one of the branches. +.PP +A branch is one\(dg or more \fIpieces\fR, concatenated. +It matches a match for the first, followed by a match for the second, etc. +.PP +A piece is an \fIatom\fR possibly followed +by a single\(dg `*', `+', `?', or \fIbound\fR. +An atom followed by `*' matches a sequence of 0 or more matches of the atom. +An atom followed by `+' matches a sequence of 1 or more matches of the atom. +An atom followed by `?' matches a sequence of 0 or 1 matches of the atom. +.PP +A \fIbound\fR is `{' followed by an unsigned decimal integer, +possibly followed by `,' +possibly followed by another unsigned decimal integer, +always followed by `}'. +The integers must lie between 0 and RE_DUP_MAX (255\(dg) inclusive, +and if there are two of them, the first may not exceed the second. +An atom followed by a bound containing one integer \fIi\fR +and no comma matches +a sequence of exactly \fIi\fR matches of the atom. +An atom followed by a bound +containing one integer \fIi\fR and a comma matches +a sequence of \fIi\fR or more matches of the atom. +An atom followed by a bound +containing two integers \fIi\fR and \fIj\fR matches +a sequence of \fIi\fR through \fIj\fR (inclusive) matches of the atom. +.PP +An atom is a regular expression enclosed in `()' (matching a match for the +regular expression), +an empty set of `()' (matching the null string)\(dg, +a \fIbracket expression\fR (see below), `.' +(matching any single character), `^' (matching the null string at the +beginning of a line), `$' (matching the null string at the +end of a line), a `\e' followed by one of the characters +`^.[$()|*+?{\e' +(matching that character taken as an ordinary character), +a `\e' followed by any other character\(dg +(matching that character taken as an ordinary character, +as if the `\e' had not been present\(dg), +or a single character with no other significance (matching that character). +A `{' followed by a character other than a digit is an ordinary +character, not the beginning of a 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 +regex(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/src/regex/regex.h b/src/regex/regex.h index a1fcec2e1c..d094d072d5 100644 --- a/src/regex/regex.h +++
