Hi,
From the documentation I can see there is quite a few introspection abilities
via the template and component variables. However I'm trying to do something a
little more complex and can't figure out if there is a straightforward way to
do this within TT or if I'm going to need to post process my output with XSLT
or similar. Here's what I'm trying to do:
In my CMS I have defined a number of wrapper templates to allow my users to
simplify and standardize our eventual output. One example of this is that I
have a 'row' wrapper that defines some div tags and css to enclose some
content. Inside each row the user can define one or more 'cell' wrappers to
add in html and css tags to properly align out content. For (simplified)
example:
[% WRAPPER row %]
[% WRAPPER cell
type = 'left' %]Some content[% END %]
[% WRAPPER cell
type = 'left' %]Some content[% END %]
[% WRAPPER cell
type = 'right' %]Some content[% END %]
[% END %]
Eventually we end up generating pages with complex layout like the following:
http://216.154.222.179:10000/previewer/communities
One of the things I am trying to do is make my processing smarter and allowing
my templates to be better at guessing what values should be. This would allow
my users to reduce the amount of stuff they put into the template, which should
reduce errors and make our templates cleaner and more consistent. For example
if the above code the 'cell' template wrapper takes a value called 'type'. I
need this information to pass to the part of the code that builds the CSS for
each cell. Basically I find that I need the last cell to have special CSS in
order to work properly. I'd like somehow to detect if the currently processing
template is the first or last in a given 'parent' but I can't figure this out.
I can see some ways to do this but they all involve creating more complex
markup then I already have.
I realize this sounds like a trivial example, but I have more complex use cases
of the above. In general I have several cases where knowing if the currently
processing template is the first or the last template for a given caller. If
hearing about that would help understand my question I will be happy to provide.
Thanks for any thoughts or suggestions.
