Hi Zak,
In this case, why wouldn't you send a tuple bar = ('foo', '2') to
template using a regexp in controller and using bar[0] ( 'foo' ) and/or
bar[1] ('2'), even ''.join(bar) ('foo2') in you template ?
Maybe I didn't understand what you want to do... But in most case, I
imagine templates using python to organize and manage the page
structure, under the conditions required by the data provided in the
render call, but not to manage data itself or make some calculus on it.
You'll always find a solution to manage to do that. This limit is easy
to remember and you can ask yourself if an operation must be done in the
python class or in the template.
The benefits of this method is to understand immediately when you face a
strange bug if you must seek and destroy it in the template or in the
controller ..
A small reminder on the way to send data in a template, if you care ;).
To send any data to a template, you can do something like this:
render.my_template(session, my_data=['tagada','tsouin'],
my_dict={'blibli': 5, 'blublu': 7}).
This way, you can use all the data you send with exactly the same data
structure.
This way, you're able to use session directly in the template, or access
my_data[1], or my_dict['blibli'] in you template.
This enable you the possibility to manage the data in any ways you want
and send exactly what you need in the template before processing it.
The only reason that would make me include some calculus in templates
would be an external event during rendering that needs a different
rendering than it would be before the render call in the python
function. In web.py, when you return render.*, alea jacta est ;).
Regards,
Christophe.

Yes, the case is kind of odd/weird.
Suppose I get a return Foo<sub>2</sub> from Control/Model, then I do a
search of Foo2 instead of Foo<sub>2</sub>, but I also need display the
original one. For example, on displaying page, I need add link on the
returns, which are displayed as it is get from database, links are.
Given the return is 'Foo<sub>2</sub>', I want:
<a href='www.foo.com/?name=Foo)>Foo<sub>2</sub></a>
I think one of solution may be,
<a href='www.foo.com/?name=$:re.sub(r'</?sub>','', 'Foo<sub>2</
sub>')>Foo<sub>2</sub></a>
I wish my poor English describe the case. Is there an alternative good
way to do the work?
Thanks for your all help.

Hi Zak,
I don't know why you want to do this substitution during rendering, it
seems to me a little odd, but possible ..
Indeed I'm curious to see why you want to process things like this,
could you explain your idea ?
Thanks ;)

Hi All,
I have a quick question. Is it possible using re.sub (python module
re) in template files? I want to do some substitution dynamically
during rendering.
Thanks.
