I pulled together a function that allows you to optionally enter a
page name into the browser like Kingdom/Animal/Canine/Dog and it
automatically converts it to Kingdom-Animal-Canine.Dog.  Works
great...  It can also take the actual page name, with the hyphens and
dot, either way.

This function works the same with or without a trailing slash.
(Basically ignores the last slash.

This change does require you to include the page name for the homepage
of each group.  But otherwise it works great. I'm looking forward to
Pm changing the core to allow admins to control the default settings
for group homepages.  This will be very helpful!

One last thing I would like to do is get the links to optionally be
formatted to go to the slash syntax, when a link is formed.  I have a
function that will take the contents of Group-Group.Name and change it
to Group/Group/Name (plus also a powerful shortcut for making links
relative to some point in the hierarchy that can be set in a config
file).  However, I'm not sure how to get this function called
properly.

I tried overwriting the $PageUrl page variable with this line but it
doesn't return anything for any of my links.  (As if group and name
are blank).

$FmtPV['$PageUrl'] = "'" . $ScriptUrl . "?n=" . hgURL("$group.$name") . "'";

If I change it to

$FmtPV['$PageUrl'] = "'" . $ScriptUrl . "?n=" . hgURL("$hggroup.$hgname") . "'";

It takes the current pagename and converts it from hyphens-dot to
slashes properly, but then every link on the page has that url.  So
the function works, but it needs to get the text of the link input
used for each instance of a link...

I also tried

$LinkPageExistsFmt = "<a class='wikilink' href='" . hgUrl($LinkUrl) .
"'>\$LinkText</a>";

but this doesn't seem to work either.

Can someone explain what I'm doing wrong...  I think this solution
will add some nice touches to the recipe, but it's a bit tricky and I
seem to need some help.

Cheers,
Dan
