RE: [NTB] Should I Upgrade to 5.2?
- Hi Alec, Thanks for the low down on the NTP updates!
Is the updated regex engine version 7 faster, or something? Will I need to
update my current RegEx clips to work with it?

Here's the What's new for 5.2

is keyboard commands under VISTA but I don't use VISTA so I might be
wrong about that.

with ^$GetDocMatchAll$, there were some other NoteTab fixes, like
Escape to incontext clipbook followed by Shift+F10, couldn't
previously select a library with an undercored letter in the list and
have the loaded library change as expected. That works now.
You can keep a backup of notepro.exe or notetab.exe when you have
concerns about updating. That way if changes are not to your liking
you can revert to the previous version.
PCRE 7 added features and fixed bugs.
I thought these were the more interesting items in the PCRE change log
Added a number of extra features that are going to be in Perl
5.10. On the whole, these are just syntactic alternatives for
features that PCRE had previously implemented using the Python
syntax or my own invention. The other formats are all retained
(a) Named groups can now be defined as (?<name>...) or
(?'name'...) as well as (?P<name>...). The new forms, as well as
being in Perl 5.10, are also .NET compatible.
(b) A recursion or subroutine call to a named group can now be
defined as (?&name) as well as (?P>name).
(c) A backreference to a named group can now be defined as
\k<name> or \k'name' as well as (?P=name). The new forms, as well
as being in Perl 5.10, are also .NET compatible.
(d) A conditional reference to a named group can now use the
syntax (?(<name>) or (?('name') as well as (?(name).
(e) A "conditional group" of the form (?(DEFINE)...) can be used
to define groups (named and numbered) that are never evaluated
inline, but can be called as "subroutines" from elsewhere. In
effect, the DEFINE condition is always false. There may be only
one alternative in such a group.
(f) A test for recursion can be given as (?(R1).. or
(?(R&name)... as well as the simple (?(R). The condition is true
only if the most recent recursion is that of the given number or
name. It does not search out through the entire recursion stack.
Add \R to match any Unicode newline sequence, as suggested in the
Unicode report. [note this token works in all files, not just unicode
For an unanchored pattern, if a match attempt fails at the start
of a newline sequence, and the newline setting is CRLF or ANY,
and the next two characters are CRLF, advance by two characters
instead of one.
