[pmwiki-devel] PmWiki Skin and Default name

[Simon]

Thanks for this awesomely comprehensive reply.

It seems to me that by setting $DefaultName it should then take priority
over the default "default"name (i.e. $Group/$Group), and that this would be
a reasonable expectation for a wiki admin that the "home page" of a group
would be preferred if there was any disambiguation.

e.g.
if (empty ($DefaultName)) then # the default
     $PagePathFmt = array('{$Group}.$1','$1.$1','$1.{$DefaultName}');
else # admin changed the 'home page'
     $PagePathFmt = array(,'$1.{$DefaultName}','{$Group}.$1','$1.$1');
endif

Many years ago the decision set set $Defaultname (to 'HomePage') was made
and its not reversible now

thanks very much

Simon
