Added some missing #if !defined NOPOSIX conditionals in pcretest.c that +had been forgotten. + +2. By using declared but undefined structures, we can avoid using "void" +definitions in pcre.h while keeping the internal definitions of the structures +private. + +3. The distribution is now built using autoconf 2.50 and libtool 1.4. From a +user point of view, this means that both static and shared libraries are built +by default, but this can be individually controlled. More of the work of +handling this static/shared cases is now inside libtool instead of PCRE's make +file. + +4. The pcretest utility is now installed along with pcregrep because it is +useful for users (to test regexs) and by doing this, it automatically gets +relinked by libtool. The documentation has been turned into a man page, so +there are now .1, .txt, and .html versions in /doc. + +5. Upgrades to pcregrep: + (i) Added long-form option names like gnu grep. + (ii) Added --help to list all options with an explanatory phrase. + (iii) Added -r, --recursive to recurse into sub-directories. + (iv) Added -f, --file to read patterns from a file. + +6. pcre_exec() was referring to its "code" argument before testing that +argument for NULL (and giving an error if it was NULL). + +7. Upgraded Makefile.in to allow for compiling in a different directory from +the source directory. + +8. Tiny buglet in pcretest: when pcre_fullinfo() was called to retrieve the +options bits, the pointer it was passed was to an int instead of to an unsigned +long int. This mattered only on 64-bit systems. + +9. Fixed typo (3.4/1) in pcre.h again. Sigh. I had changed pcre.h (which is +generated) instead of pcre.in, which it its source. Also made the same change +in several of the .c files. + +10. A new release of gcc defines printf() as a macro, which broke pcretest +because it had an ifdef in the middle of a string argument for printf(). Fixed +by using separate calls to printf(). + +11. Added --enable-newline-is-cr and --enable-newline-is-lf to the configure +script, to force use of CR or LF instead of \n in the source. On non-Unix +systems, the value can be set in config.h. + +12. The limit of 200 on non-capturing parentheses is a _nesting_ limit, not an +absolute limit. Changed the text of the error message to make this clear, and +likewise updated the man page. + +13.

If it is given only one filename argument, it reads from +that file and writes to stdout. Otherwise, it reads from stdin and writes to +stdout, and prompts for each line of input, using "re>" to prompt for regular +expressions, and "data>" to prompt for data lines. + +The program handles any number of sets of input on a single input file. Each +set starts with a regular expression, and continues with any number of data +lines to be matched against the pattern. An empty line signals the end of the +data lines, at which point a new regular expression is read. The regular +expressions are given enclosed in any non-alphameric delimiters other than +backslash, for example + + /(a|bc)x+yz/ + +White space before the initial delimiter is ignored. A regular expression may +be continued over several input lines, in which case the newline characters are +included within it. It is possible to include the delimiter within the pattern +by escaping it, for example + + /abc\\/def/ + +If you do so, the escape and the delimiter form part of the pattern, but since +delimiters are always non-alphameric, this does not affect its interpretation. +If the terminating delimiter is immediately followed by a backslash, for +example, + + /abc/\\ + +then a backslash is added to the end of the pattern. This is done to provide a +way of testing the error condition that arises if a pattern finishes with a +backslash, because + + /abc\\/ + +is interpreted as the first line of a pattern that starts with "abc/", causing +pcretest to read the next line as a continuation of the regular expression. + + +.SH PATTERN MODIFIERS + +The pattern may be followed by \fBi\fR, \fBm\fR, \fBs\fR, or \fBx\fR to set the +PCRE_CASELESS, PCRE_MULTILINE, PCRE_DOTALL, or PCRE_EXTENDED options, +respectively. For example: + + /caseless/i + +These modifier letters have the same effect as they do in Perl. There are +others which set PCRE options that do not correspond to anything in Perl: +\fB/A\fR, \fB/E\fR, and \fB/X\fR set PCRE_ANCHORED, PCRE_DOLLAR_ENDONLY, and +PCRE_EXTRA respectively. + +Searching for all possible matches within each subject string can be requested +by the \fB/g\fR or \fB/G\fR modifier. After finding a match, PCRE is called +again to search the remainder of the subject string. The difference between +\fB/g\fR and \fB/G\fR is that the former uses the \fIstartoffset\fR argument to +\fBpcre_exec()\fR to start searching at a new point within the entire string +(which is in effect what Perl does), whereas the latter passes over a shortened +substring. This makes a difference to the matching process if the pattern +begins with a lookbehind assertion (including \\b or \\B). + +If any call to \fBpcre_exec()\fR in a \fB/g\fR or \fB/G\fR sequence matches an +empty string, the next call is done with the PCRE_NOTEMPTY and PCRE_ANCHORED +flags set in order to search for another, non-empty, match at the same point. +If this second match fails, the start offset is advanced by one, and the normal +match is retried. This imitates the way Perl handles such cases when using the +\fB/g\fR modifier or the \fBsplit()\fR function. + +There are a number of other modifiers for controlling the way \fBpcretest\fR +operates. + +The \fB/+\fR modifier requests that as well as outputting the substring that +matched the entire pattern, pcretest should in addition output the remainder of +the subject string. This is useful for tests where the subject contains +multiple copies of the same substring. + +The \fB/L\fR modifier must be followed directly by the name of a locale, for +example, + + /pattern/Lfr + +For this reason, it must be the last modifier letter. The given locale is set, +\fBpcre_maketables()\fR is called to build a set of character tables for the +locale, and this is then passed to \fBpcre_compile()\fR when compiling the +regular expression. Without an \fB/L\fR modifier, NULL is passed as the tables +pointer; that is, \fB/L\fR applies only to the expression on which it appears. + +The \fB/I\fR modifier requests that \fBpcretest\fR output information about the +compiled expression (whether it is anchored, has a fixed first character, and +so on). It does this by calling \fBpcre_fullinfo()\fR after compiling an +expression, and outputting the information it gets back. If the pattern is +studied, the results of that are also output. + +The \fB/D\fR modifier is a PCRE debugging feature, which also assumes \fB/I\fR. +It causes the internal form of compiled regular expressions to be output after +compilation. + +The \fB/S\fR modifier causes \fBpcre_study()\fR to be called after the +expression has been compiled, and the results used when the expression is +matched. + +The \fB/M\fR modifier causes the size of memory block used to hold the compiled +pattern to be output. + +The \fB/P\fR modifier causes \fBpcretest\fR to call PCRE via the POSIX wrapper +API rather than its native API. When this is done, all other modifiers except +\fB/i\fR, \fB/m\fR, and \fB/+\fR are ignored. REG_ICASE is set if \fB/i\fR is +present, and REG_NEWLINE is set if \fB/m\fR is present. The wrapper functions +force PCRE_DOLLAR_ENDONLY always, and PCRE_DOTALL unless REG_NEWLINE is set. + +The \fB/8\fR modifier causes \fBpcretest\fR to call PCRE with the PCRE_UTF8 +option set. This turns on the (currently incomplete) support for UTF-8 +character handling in PCRE, provided that it was compiled with this support +enabled. This modifier also causes any non-printing characters in output +strings to be printed using the \\x{hh...} notation if they are valid UTF-8 +sequences. + + +.SH DATA LINES + +Before each data line is passed to \fBpcre_exec()\fR, leading and trailing +whitespace is removed, and it is then scanned for \\ escapes. The following are +recognized: + + \\a alarm (= BEL) + \\b backspace + \\e escape + \\f formfeed + \\n newline + \\r carriage return + \\t tab + \\v vertical tab + \\nnn octal character (up to 3 octal digits) + \\xhh hexadecimal character (up to 2 hex digits) + \\x{hh...} hexadecimal UTF-8 character + + \\A pass the PCRE_ANCHORED option to \fBpcre_exec()\fR + \\B pass the PCRE_NOTBOL option to \fBpcre_exec()\fR + \\Cdd call pcre_copy_substring() for substring dd + after a successful match (any decimal number + less than 32) + \\Gdd call pcre_get_substring() for substring dd + after a successful match (any decimal number + less than 32) + \\L call pcre_get_substringlist() after a + successful match + \\N pass the PCRE_NOTEMPTY option to \fBpcre_exec()\fR + \\Odd set the size of the output vector passed to + \fBpcre_exec()\fR to dd (any number of decimal + digits) + \\Z pass the PCRE_NOTEOL option to \fBpcre_exec()\fR + +When \\O is used, it may be higher or lower than the size set by the \fB-O\fR +option (or defaulted to 45); \\O applies only to the call of \fBpcre_exec()\fR +for the line in which it appears. + +A backslash followed by anything else just escapes the anything else. If the +very last character is a backslash, it is ignored. This gives a way of passing +an empty line as data, since a real empty line terminates the data input. + +If \fB/P\fR was present on the regex, causing the POSIX wrapper API to be used, +only \fB\B\fR, and \fB\Z\fR have any effect, causing REG_NOTBOL and REG_NOTEOL +to be passed to \fBregexec()\fR respectively. + +The use of \\x{hh...} to represent UTF-8 characters is not dependent on the use +of the \fB/8\fR modifier on the pattern. It is recognized always. There may be +any number of hexadecimal digits inside the braces. The result is from one to +six bytes, encoded according to the UTF-8 rules. + + +.SH OUTPUT FROM PCRETEST + +When a match succeeds, pcretest outputs the list of captured substrings that +\fBpcre_exec()\fR returns, starting with number 0 for the string that matched +the whole pattern.

Otherwise, it reads from stdin and writes to stdout, + and prompts for each line of input, using "re>" to prompt + for regular expressions, and "data>" to prompt for data + lines. -The /L modifier must be followed directly by the name of a locale, for example, + The program handles any number of sets of input on a single + input file. Each set starts with a regular expression, and + continues with any number of data lines to be matched + against the pattern.
