I'm having difficulty figuring out how to make METAL macros reusable.
Is it standard practice to put macros into a common folder where they can
be used by numerous different websites?
I just can't get a handle on how they are supposed to be used.
According to:-
http://www.zope.org/Documentation/Books/ZopeBook/2_6Edition/AppendixC.stx
Macros provide a way to define a chunk of presentation in one template,
and share it in others, so that changes to the macro are immediately
reflected in all of the places that share it. Additionally, macros are
always fully expanded, even in a template's source text, so that the
template appears very similar to its final rendering.
This does not really tell me how they should be used. Can someone give me
an example of real world usage?
Hi John,
This is about as simple as it gets (sorry if i misunderstood your question):
(1) Name this page template ptMacros
<html>
<body>
This is Page Template <em tal:content="template/id">template id</em>.
<p metal:define-macro="copyright">
Copyright 2001, <em>Foobar</em> Inc.
</p>
</body>
</html>
(2) name this page template ptTest
<html>
<body>
This is Page Template <em tal:content="template/id">template id</em>.
<p metal:use-macro="container/ptMacros/macros/copyright">
<b metal:fill-slot="name">Copyright goes here</b>
</p>
</body>
</html>
And test it out.
David
