News about PCRE releases
|
||
|
|
------------------------
|
||
|
|
|
||
|
|
Release 3.3 01-Aug-00
|
||
|
|
---------------------
|
||
|
|
|
||
|
|
There is some support for UTF-8 character strings. This is incomplete and
|
||
|
|
experimental. The documentation describes what is and what is not implemented.
|
||
|
|
Otherwise, this is just a bug-fixing release.
|
||
|
|
|
||
|
|
|
||
|
|
Release 3.0 01-Feb-00
|
||
|
|
---------------------
|
||
|
|
|
||
|
|
1. A "configure" script is now used to configure PCRE for Unix systems. It
|
||
|
|
builds a Makefile, a config.h file, and the pcre-config script.
|
||
|
|
|
||
|
|
2. PCRE is built as a shared library by default.
|
||
|
|
|
||
|
|
3. There is support for POSIX classes such as [:alpha:].
|
||
|
|
|
||
|
|
5. There is an experimental recursion feature.
|
||
|
|
|

IMPORTANT FOR THOSE UPGRADING FROM VERSIONS BEFORE 2.00
|
||
|
|
|
||
|
|
Please note that there has been a change in the API such that a larger
|
||
|
|
ovector is required at matching time, to provide some additional workspace.
|
||
|
|
The new man page has details. This change was necessary in order to support
|
||
|
|
some of the new functionality in Perl 5.005.
|
||
|
|
|
||
|
|
IMPORTANT FOR THOSE UPGRADING FROM VERSION 2.00
|
||
|
|
|
||
|
|
Another (I hope this is the last!) change has been made to the API for the
|
||
|
|
pcre_compile() function. An additional argument has been added to make it
|
||
|
|
possible to pass over a pointer to character tables built in the current
|
||
|
|
locale by pcre_maketables(). To use the default tables, this new arguement
|
||
|
|
should be passed as NULL.
|
||
|
|
|
||
|
|
IMPORTANT FOR THOSE UPGRADING FROM VERSION 2.05
|
||
|
|
|
||
|
|
Yet another (and again I hope this really is the last) change has been made
|
||
|
|
to the API for the pcre_exec() function. An additional argument has been
|
||
|
|
added to make it possible to start the match other than at the start of the
|
||
|
|
subject string. This is important if there are lookbehinds. The new man
|
||
|
|
page has the details, but you just want to convert existing programs, all
|
||
|
|
you need to do is to stick in a new fifth argument to pcre_exec(), with a
|
||
|
|
value of zero. For example, change
|
||
|
|
|
||
|
|
pcre_exec(pattern, extra, subject, length, options, ovec, ovecsize)
|
||
|
|
to
|
||
|
|
pcre_exec(pattern, extra, subject, length, 0, options, ovec, ovecsize)
|
||
|
|
|
