The change introduced in 13367 breaks Perl 5.6.1

I get this error when running configure

Error: TWiki.pm could not be loaded. The error was:
Global symbol "@back" requires explicit package name at /var/www/twiki/lib/TWiki/Render.pm line 1814.
Global symbol "@back" requires explicit package name at /var/www/twiki/lib/TWiki/Render.pm line 1821.
Compilation failed in require at /var/www/twiki/lib/TWiki.pm line 493.

Compilation failed in require at (eval 84) line 3.
Error: Check path to twiki/lib and check that LocalSite.cfg is present and readable 

I do not get this in Perl 5.8

I think it is this syntax that is not valid in 5.6

my( $bow, $eow, $forward, $back ) = ( '\b', '\b', '?=', '?<=' );

-- TWiki:Main/KennethLavrsen - 13 Apr 2007

No the line is OK.

It is the ${back}[^./] that seems to be seen as an array.

Easy to fix.

$re = "((${back}" . "[^./])|^)$bow($matchWeb\\.)?$topic$eow";


$re = "((${back}" . "[^./])|^)$bow$matchWeb\\.$topic$eow";

-- TWiki:Main.KennethLavrsen - 13 Apr 2007

Fix implemented and re-implemented.

Remember to merge this to Patch when SVN

-- TWiki:Main.KennethLavrsen - 13 Apr 2007

I beleiev this is fixed.


Cleaned "WaitingFor" field.
