shpaml + pyramid + mako
Erez
automatically convert all of my templates to html on runtime.
It's a bit slower than static compilation, of course, but
1) shpaml's operation is potentially very fast (if it isn't already)
2) a good webserver will cache its pages anyway
3) It's so much easier to work with
My solution is undoubtedly a bit hackish, but I figured I'd share it
and maybe it will inspire someone to post a better solution.
In my project's __init__.py, I added these lines:
import shpaml
from pyramid import mako_templating
class ShpamlRenderer(object):
def __init__(self, info):
self.makoRenderer = mako_templating.renderer_factory(info)
def __call__(self, value, system):
result = self.makoRenderer(value, system)
return shpaml.convert_text(result)
and in the main() function, I added:
....
config.add_renderer(name=".mako", factory=ShpamlRenderer)
....
Now all mako templates pass through the shpaml preprocessor!
Here's an example:
template.mako:
----------------------
html
body
%for row in range(4):
.link
a.pretty_link href="${row}" | link${row}
%endfor
---- turns into ----->>
<html>
<body>
<div class="link">
<a href="0" class="pretty_link">link0</a>
</div>
<div class="link">
<a href="1" class="pretty_link">link1</a>
</div>
<div class="link">
<a href="2" class="pretty_link">link2</a>
</div>
<div class="link">
<a href="3" class="pretty_link">link3</a>
</div>
</body>
</html>

first render through mako, which creates shpaml, then you convert the shpaml to
html.
I've mostly seen the reverse approach. For example, I convert shpaml to django,
then render the django. This makes sense in the django world, because it's
pretty easy for shpaml to detect parts of the document that are django and just
leave them alone. With mako, that's not so easy, as mako allows for more use of
inline Python blocks. So I think your approach makes sense.
Shpaml's pretty fast, because it doesn't do a whole heck of a lot. On my Mac I
see that it can process about 20,000 lines per second. (It's a 2.66 GHz Intel
Core 2 Duo.)

when I use inheritance, I write base.mako:
html
body
wrap
${self.wrap()}
and view.mako:
<%inherit file="base.mako"/>
<%def name="wrap()">
p | sth
</%def>
I need make current indentation, and it drive me mad, any way to solve
this?

when I need import some text in mako like:
<textarea name="body" rows="10" cols="60">
${page.data}
</textarea>
shpaml's grammar don't have block text quote...
so looks like text -> shpaml -> mako is the better solution?

It probably make sense to do it that way.
Later versions of shpaml support the "VERBATIM" keyword, which might solve your
problem:
import shpaml
test = '''
blockquote VERBATIM
Here we are with
some text that is indented, and
we want
sphaml to just let it pass through
p
Back to the normal mode of shpaml.
'''
print shpaml.convert_text(test)

issue, because shpaml won't run on base.mako.
(and it can't do so without parsing and understanding mako)
If ${self.wrap()} doesn't insert code in the right indentation,
perhaps prefixing it with a nop character can help?
(like: @ ${self.wrap()} )
Otherwise, perhaps a new shpaml construct could be introduced for such
situations.
For example:
html
body
wrap
!BLOCK
div
p | bla
!END
in which the contents of the block will be "indented" to reside in
wrap
I say "indented" because if BLOCK only pretends to indent, without
actually doing so (which is faster),
it could solve your (second) issue as well.

and for the first question, I'm checking how to rending shpaml before
send file to mako....
