include file containing namespaces

[binadam]

I have a file called "namespaces.mako":

<%namespace name="a" file="a:templates/base.html" />

<%namespace name="b" file="b:templates/base.html" />

Now I want to be able to use these namespaces in different files, as:

<%include file="namespaces.mako" />

${a.foo()}

But this doesn't work. What's the correct way to do this?

Thanks.

Guess I should mention the error:

AttributeError: 'Undefined' object has no attribute 'foo'

that would be something like a "static include" but that's not something Mako has.

There's really not a built in function for this, the best you could do would be something like building a custom preprocessor that adds in <%namespace> tags, if you wanted to do that you could use the "preprocessor" argument to Template / TemplateLookup.
