[Caml-list] ANNOUNCE: lablpcre-1.0 - a PCRE binding for Objective Caml

[Robert Roessler]

The "1.0" release of the LablPCRE OCaml binding for PCRE is now
available, fully supporting Linux and Windows builds PCRE versions 6.1
- 7.0 (current).

LablPCRE provides simple and easy to use access to regular expression
matching, offering a rich module-based interface based on PCRE's POSIX
functions wrapper.

This release has been built and tested using OCaml 3.09.3 on Fedora
Core 6 and Windows XP, supports findlib and "hands-off" building and
installing (no "configure" script or manual file editing required),
and has pre-built binaries for [native] Windows XP. The full package
is licensed under the "new" BSD license, and may be downloaded here:

Can you (or anyone familiar with both) summarize how this binding
compares to Markus Mottl's pcre-ocaml? Thanks.

I don't know much about it, but it seems to implement the API for
POSIX-style regular expressions whereas pcre-ocaml implements Perl
compatibility regular expressions. There are obviously no functions for
string substitution, etc., in LablPCRE (yet).

Regards,
Markus

As Markus says, it does implement the POSIX API for regular expression
matching and extraction of sub-patterns... but note that that just
[here] controls the "level" of the interface: there is a regcomp
function for compiling the patterns and a regexec call for matching a
compiled pattern against a specific string.

The full "language" of PCRE for matching and pattern specification is
accepted. Further, LablPCRE adds an even lighter-weight regmatch
function when all that is desired is a boolean answer on a match, as
well as a set of substring extraction and [error] status info accessor
functions.

LablPCRE makes an effort to be a good GC-citizen by not holding
references to anything it doesn't need to. :)

Finally, LablPCRE supports PCRE 7.0 (or any of the releases back to 6.1).
