Thanks to Gerd Stolpmann <firstname.lastname@example.org> for the patch! 2009-05-07: Changed API wrt. error handling and thus made a major release. Improved behavior in the presence of recursion limit errors. Thanks to Martin Jambon <email@example.com> for this patch! 2009-04-23: Fixed build problem on MinGW. Thanks to Gerd Stolpmann <firstname.lastname@example.org> for the patch! 2009-03-08: Fixed build problem on Mac OS X with macports. Thanks to Ralph Douglass <email@example.com> for the initial patch. Update OCamlMakefile. Improved Godi-distribution. 2008-05-06: Fixed build problem with newer versions of PCRE. 2008-03-14: Synced with Jane Street tree. 2008-01-25: Added new function: * names This function returns the names of all named substrings in a regular expression. Thanks to Benedikt Grundmann <firstname.lastname@example.org> for the patch! 2007-07-12: Improved build scripts for Windows. Thanks to Christophe Troestler <Christophe.Troestler@umh.ac.be> for the patch! 2007-07-12: Improved documentation for Win32 builds, and added some build scripts usable on Windows. Thanks to Christophe Troestler <Christophe.Troestler@umh.ac.be> for this contribution! 2007-04-23: callback_exn -> caml_callback_exn. Updated OCamlMakefile. 2006-11-22: Updated OCamlMakefile. 2006-06-11: Updated to pcre-5.0! New representation for callbacks: they now take only one argument (a record of the callback data). Added partial matching and auto callouts. 2006-01-16: Updated OCamlMakefile. Removed a superfluous binding. 2005-08-18: Fixed a small compilation problem on rare platforms by upgrading OCamlMakefile. 2005-06-08: Relaxed license. Fixed copyright headers. 2005-05-31: Fixed some uncleanliness reported by Saffire (FFI-type checker). 2004-09-17: Fixed a bug concerning null patterns in exec_all (extract_all and extract_all_opt are also affected). Updated OCamlMakefile. 2004-05-19: Updated Makefile.mingw. Thanks to Jeff Henrikson <email@example.com> for the patch! Updated OCamlMakefile. 2004-04-29: Changed behaviour of "get_substring"!!! It now does not return the empty string anymore if an accessed substring was not captured. It raises the exception "Not_found" instead. Three new functions: * get_opt_substrings * extract_opt * extract_all_opt These behave like the functions without "opt", but return "Some substring" if a substring was captured, and "None" otherwise. 2004-04-27: Updated OCamlMakefile. 2004-04-24: Updated OCamlMakefile. 2004-03-28: Changed interface to build-time configuration functions of PCRE. Updated OCamlMakefile. 2004-02-21: Added CAMLprim in the C-interface where appropriate. 2004-02-08: Fixed a minor bug concerning returning unit values from C. 2004-01-31: Added pcre_make.win32/Makefile.mingw. Thanks to Jeffrey Henrikson <JEFHEN@SAFECO.com> for this contribution! Update OCamlMakefile. 2004-01-13: Updated pcre_make.win32/pcre.h. 2003-12-30: Fixed documentation. 2003-12-21: Updated to pcre-4.5! New function: * config_stackrecurse New exception: * BadUTF8Offset Updated OCamlMakefile. 2003-12-19: Fixed a small (but probably unnoticable) bug concerning allocation of optional values in the C-stubs. 2003-12-12: Updated OCamlMakefile. Renamed stubs (invisible to users). 2003-11-16: Updated pcre_make.win32/pcre.h to reflect newest PCRE-version. May help Windows users. 2003-10-08: Upgraded to pcre-4.4! New flag for compiling patterns: NO_UTF8_CHECK New exception: BadUTF8 Updated OCamlMakefile. 2003-09-30: Fixed a bug in the documentation. Updated OCamlMakefile. 2003-06-17: Fixed a bug in the documentation. Updated OCamlMakefile. 2003-05-29: Updated to pcre-4.3! Major change: callouts are now fully supported! This allows the matching engine call OCaml-code while matching - quite powerful! Please see the interface specification for more information. Many small changes (improvements) in C-code. Updated documentation. 2003-04-08: Updated OCamlMakefile. Reformatted documentation. 2003-03-20: Added new function "get_subject". Patched OCamlMakefile. 2003-03-18: Major update: upgraded to pcre-4.1! Better UTF8-support. New flag "NO_AUTO_CAPTURE". New values: * config_utf8 * config_newline * config_link_size * config_match_limit Renamed all occurrences of "firstchar" to "firstbyte". New functions: * studysize * namecount * nameentrysize * get_stringnumber Updated OCamlMakefile. 2003-01-07: Updated OCamlMakefile to make use of "findlib". Added support for UTF-8 character encodings. Better installation and documentation for Win32. Thanks to Artem Prisyznuk <firstname.lastname@example.org> for the above patches! 2002-12-14: Fixed a bug concerning zero-sized matches effecting "replace", "qreplace", "substitute_substrings" and "substitute". Updated OCamlMakefile. 2002-12-08: Improved documentation of "pcre_exec". 2002-11-24: Fixed a bug in "full_split" concerning matched subgroups. 2002-11-12: Added a new function "extract_all" (see interface documentation). 2002-08-16: Fixed a bug in the "split"-function: The Perl-splitting semantics was not completely adhered to: leading whitespace was stripped after the matching process rather than before, which lead to incompatible behaviour when a maximum bound was used. Thanks to Yutaka Oiwa <email@example.com> for the bug report! Updated OCamlMakefile. 2002-07-31: Fixed a bug in the following functions: * replace * qreplace * substitute_substrings Transformed most part of the library to make it slightly more efficient and simple. The interface is still the same! Updated OCamlMakefile + documentation. 2002-07-15: Fixed a mistake in the documentation. 2002-05-05: Fixed a bug with the generation of byte-code libraries that dynamically link the PCRE. 2002-05-01: Removed C-library from distribution! Users must install it on their own now. Reorganized whole distribution and updated OCamlMakefile again for better support of dynamic and/or static libraries. 2002-04-30: Updated OcamlMakefile: it does not ask for confirmation during installation anymore! 2002-03-06: Upgraded to pcre-3.9. This should not change anything for OCaml-users. 2002-03-01: Updated OcamlMakefile. 2002-02-24: Separated compilation of library and examples to prevent confusions when the library needs to be installed before one can build the examples. 2002-02-15: Fixed a bug in the pcre_exec-function which was introduced ten days ago during correction of another bug (thanks to Gerd Stolpmann for the report!). 2002-02-15: Added the option to compile the library statically only. Updated INSTALL-notes to explain possible installation problems associated with support of dynamic linking. Added META-file for findlib. 2002-02-12: Rewrote interface documentation to support OCamldoc. Fixed a portability bug with shared libraries. 2002-02-10: Removed project from Sourceforge for simpler maintainance. 2002-02-07: Important news: library is linked dynamically now by default. 2002-02-06: Fixed a stupid bug affecting the following functions (thanks to Jacek Chrzaszcz for the bug report!): * num_of_subs * get_substring * get_substring_ofs * get_substrings * extract Also done: converted literal pattern strings in the library and the cloc-example so that the escape char (backslash) does not cause warnings anymore with the new OCaml-release. The latter is more paranoid about unknown escape combinations, requiring the user to add extra backslashes. 2002-01-07: Fixed a stupid bug: the position argument (offset) was not correctly handled in replacement and substitution functions, leading to wrong results. As it seems, people seldom use arguments other than zero... The "subst"-example now assumes that offsets other than zero should not lead to an error if it exceeds the line length. The line is just copied instead. 2001-12-28: Added README.win32 (courtesy of John W. Small). Updated README so that it is generated by Hevea. 2001-11-19: Upgraded to the newest release of the underlying C-library (PCRE-3.7). Added a tiny patch to satisfy the Visual C++ compiler under W2K (thanks to John W. Small!). Updated contact address. 2001-11-17: Updated OcamlMakefile. 2001-09-15: Upgraded to the newest release of the underlying C-library (PCRE-3.5). Added a new function: substitute_substrings It is similar to "substitute", but takes the full substring information of the match rather than the matching string. Thanks to Patrick M. Doane for proposing this missing feature! 2001-09-07: Updated OcamlMakefile 2001-08-27: Fixed a bug in the splitting function: leading whitespace was accidently always removed when using a regular expression rather than a pattern. This behaviour should only happen for the default whitespace pattern, which is used if you do not specify any pattern or regexp in the function call. 2001-06-30: Removed "Printexc.catch" from examples: is going to be deprecated in upcoming OCaml-release. 2001-05-22: Fixed typo in documentation. 2001-04-25: Added a new function: asplit It is identical to "split" with the exception that it returns a string array instead of a string list. This makes it easier for the user to access strings by index. Added a new option to "get_substrings" and "extract": full_match When "full_match" is true (default: yes), then the resulting string array will contain the full match at index 0, otherwise the result will only contain captured substrings. Removed superfluous comments in "pcre.ml": they are already present in the interface documentation anyway. 2001-04-08: Small patch that makes this library compile on OpenBSD, too. 2001-01-30: Made Makefile more general (allows simpler addition of further examples). 2001-01-24: Updated OcamlMakefile: made default definition of "OCAMLLIBPATH" backwards compatible again: some people do not use the CVS-version of OCaml, which supports the "-where"-option. People with the new compiler will not notice any effect. 2001-01-06: Added a new function: exec_all It allows you to execute pattern matching over a whole string until no more matches can be found: then it returns the array of all matching "substrings". You can extract subpatterns of each of those matching substrings again with the usual functions. Fixed a minor inconsistency in "next_match". 2000-12-23: Updated OcamlMakefile: makes use of the new "-where"-keyword to find the path to the standard library if it is not defined. 2000-12-14: Pedantry in the C-interface: added "const" qualifiers. 2000-12-09: Made some functions tail-recursive (very unlikely to cause any noticable effect for most people). 2000-12-02: Cleaned up the code a bit for distribution on SourceForge. Speed of some operations should be very slightly improved, too. 2000-11-16: Fixed a stupid bug that could crash your programs under rare circumstances (when you use faulty regular expressions). Added an internally used exception (InternalError) to the interface of the library. This allows the user to handle the case when the C-engine exhibits undefined behaviour (should never happen, anyway). 2000-09-27: Upgraded to the newest release of the underlying C-library (PCRE-3.4). See "pcre-C/ChangeLog" for more information (mostly minor bugfixes). Renamed "pgrep" to "pcregrep" to prevent name hiding on Solaris (change as suggested in the C-library distribution). 2000-06-24: Updated OcamlMakefile 2000-06-13: Updated OcamlMakefile 2000-06-12: Mini-optimisation: lifted a pure value out of a function body. 2000-06-11: Updated OcamlMakefile 2000-06-08: Added installation routine + updated OcamlMakefile again: This upgrade makes installation much easier! Read the updated INSTALL-file! 2000-06-07: Updated to new OcamlMakefile 2000-06-05: Added a new function: get_substring_ofs substrings n This allows you to get the offset positions of the matching pattern and the substrings directly from a value of type "substring". See the interface documentation for details. 2000-05-15: Upgraded to the newest release of the underlying C-library (PCRE-3.2). This does not add new features, but is said to fix some PERL-compatibility bugs and improves portability. 2000-05-04: Minor update of C-interface: Use the new "hash_variant"-function to compute the hash value of variants (used Callback.register before - a bit clumsy). 2000-04-24: New release: compiles with OCaml-3.00. Lots of changes in interface! OCaml-3.00 introduced some syntax changes for labels. Additionally, no keywords are allowed for them. All this required quite some renamings. I tried to stick to the new labels of the "str"-library as close as makes sense. Sorry for this inconvenience, but I think that adhering to some "standard" is a Good Thing... For further information on the changes, look at the documentation of the interface file. 2000-04-23: Minor cleanup of C-interface: Made local functions + variables static and moved a check for error codes (lint should be happier now). 2000-04-01: Changed linking of the library again (marginally): The new linking semantics for byte code libraries allows passing of flags that are remembered. This then only requires linking executables against "pcre.cma" - the C-library ("libpcre.a") will be linked in automatically. 2000-03-30: Cleaned up the C-interface: Removed a possible bug in the allocation of firstchar values. Saner handling of polymorphic variants (not hard-wired integers anymore - registered via callbacks). Better GC-settings: much nicer to the GC now (fewer full cycles - hardly more memory consumption). Should make programs run slightly faster when regular expressions are often allocated. Changed linking of the library to suit the semantics of the upcoming OCaml-major release (backward compatible). 2000-02-07: Changed interface of function "foreach_file": No idea why I implemented a tuple in the interface instead of a curried function. Must have been the drugs... ;-) Former interface: val foreach_file : string list -> (string * in_channel -> unit) -> unit Current interface: val foreach_file : string list -> (string -> in_channel -> unit) -> unit Additionally, this function now also closes the file channel in case of an exception. The exception gets reraised, of course. 2000-02-05: Eliminated a PERL-incompatibility of the "split"-function: When neither the pattern nor the compiled regular expression are specified, "split" defaults to a whitespace pattern. However, PERL additionally strips leading whitespace, but *only* when in "default" mode. This last "feature" (?) was overseen during the introduction of labels and default arguments. 2000-02-05: Updated the C-library to the newest release (pcre-3.0). This is a major release, but the changes to the OCaml-part are rather small: just the functionality concerning information on compiled patterns has changed. Instead of the former "info"-function, several ones are provided. I think this is the most convenient way to handle this, because it does not force the user to do explicit pattern matching on results: due to the number of new info-options this would have been rather confusing. Because the old PCRE-function "pcre_info" is obsolete, I chose to drop its OCaml-interface completely. I do not think that it is an often used part, anyway. See the interface file and the ChangeLog + documentation of the C-library to see, what has changed in detail. The other few changes just marginally effect efficiency. One bug was present in the last release in the "info"-part (polymorphic variants were not correctly represented). This has changed anyway and should work fine now. 2000-01-10: "foreach_line" uses stdin as labeled (label: 'in') default argument now. 1999-12-29: Lots of changes: * Uses the new features of OCaml 2.99: Labeled parameters and default arguments for much more convenience. E.g. write split pos:1 "foo bar" to get the list ["oo"; "bar"]. Polymorphic variants for passing options: this change allows, for example, using the data constructor "ANCHORED" for both compiling flags and at matching time instead of "C_ANCHORED" and "R_ANCHORED". * Got rid of all the superfluous shortcuts, like "bounded_psplit" and the like. Labeled parameters are much more readable and convenient. * Removed the functions compatible to the "Str"-module. It's probably rather confusing for people to see two different kinds of implementations. * Renamed functions due to the use of labels and the removing of the obsolete compatibility functions. * Updated documentation with more details on using the library. 1999-12-21: Small change (2 chars...) to make the C-interface compile with the newest release (OCaml 2.99). 1999-09-27: Fixed a bug which occurs, when replacements or substitutions in strings are longer than the subject string itself. This concerns functions "replace_all", "qreplace_all" and "substitute_all" + their variants. THANKS to GERD STOLPMANN (Gerd.Stolpmann@darmstadt.netsurf.de) for finding another bug! 1999-09-21: Fixed some bugs in "pcre_intf.c": "Store_field" was used inappropriately throughout the file, which could lead to segfaults in the garbage collector. This was corrected by using the "Field"-macro where appropriate. Protected an input parameter from being reclaimed too early. Initialized a field before throwing an exception to please the GC. The GC should be happy now... THANKS to GERD STOLPMANN (Gerd.Stolpmann@darmstadt.netsurf.de) for the patch! 1999-08-31: Updated to pcre-2.08 - this should fix some bugs. See "pcre-C/ChangeLog" for details. Renamed directory "pcre-C-2.07" to "pcre-C" to allow for easier upgrading. Added CVS-info to sources. 1999-08-24: Updated to pcre-2.07. Splitting is 100% PERL-compatible now. New runtime option: NOTEMPTY (see interface for details). Two additional examples: cloc and count_hash. New functions: sregexpo, sregexp, sregexp_case_fold. 1999-08-02: Exception handling more regular now: Raises [Invalid_argument] instead of [Failure] where appropriate. Raises [InternalError] if C-library exhibits undefined behaviour (has never happened so far). Updated comments. 1999-07-30: Bugfix in "pcre_intf.c": "pcre_ocaml" should work now on 64-bit architectures... 1999-07-29: Small fix in "pcre_intf.c": strict compilers (gcc is not very strict) otherwise complain about undefined behaviour in a certain line. Explicitely mention all include files. Removed unused variable. Also moved a line for efficiency... 1999-07-28: First release.
