[pmwiki-users] Page list templates

[Petko Yotov]

You could add a custom page variable holding the first 4 letters of 
$Name:

In local configuration:

   $FmtPV['$Name04'] = 'substr($name, 0, 4)';

And use that in a template:

(:template first "{=$Name04}":)
'''{=$Name04}:'''

This may work best if the pagelist is ordered by name.
