[pmwiki-users] Truncate PageTitle

Did the $FmtPV definition work?  Or were you hoping for something
markup-expression related?

Writing a strpos() in MX is fairly simple:

$MarkupExpr['strpos'] = 'strpos($args[0], $args[1])';
# $MarkupExpr['add'] = '$args[0] + $args[1]'; // MarkupExprPlus
version is better, this will work

Then in page source:

{(substr "{$Title}" (add 2 (strpos "{$Title}" "-")))}

You have to add 2 because of the space after the dash.  If you search
for space-dash-space then you would add 3...

Be aware that if an author doesn't title a page just right the results
could be unacceptable...
