Yeah, that's why I don't like it. OTOH, this is indeed the shortest way if you
want true and false. Here's how to do this:
sub password_matches__true___open {
return 'if (crypt($attr_clear,$attr_encrypted) eq $attr_encrypted) {'
}
sub password_matches__true {
return '}'
}
sub password_matches : expr child(encrypted,clear) {
...
}
I hope you get the idea. $attr_foo is in scope for the child elements as well
unless there's some other element in between which overrides it. We depend on
auth:clear and auth:encrypted to occur before auth:true, obviously.
Btw, in "password_matches__true___open" that's one underscore for the "-" in
"password-matches", two underscores for matching auth:true only below
auth:password-matches, and then three to specify the open-event.

hmm... there is auth:has-permission. Actually, I begin to like your idea. I
only wished there was something I could do to generalize this, as it is
obviously fot for many places. Perhaps some additional SimpleTaglib
feature... well anyways, look at the example above, it applies here
similarly.

Not too bad, really. I once planned SimpleTaglib to support this directly, but
I'm not sure if it's worth the trouble.
I hope you get your ideas done from the example above.
