Greetings Nathan, Hampton, Haml/Sass users, All ...
As far as I know - there is no way to use "external" (haml scope) variables
inside a filter, please correct me if I am wrong.
I wrote a really simple filter that "requires" me to have variables, and I
want to suggest a syntax that will look natural to all developers using
ruby.
My filter is "javascript", and the filter class is extremely simple, here is
the render filter method:
def render
return <<-EOT
<script type=\"text/javascript\">
//<![CDATA[
[EMAIL PROTECTED]
//]]>
</script>
EOT
end
If only I could replace the '[EMAIL PROTECTED]' with '#{eval(@text)}', then I
could
use variables that Haml passed to the filter. Or if for some reason I dont
like 'eval', I could also use gsub to replace all '#id' and '#{id}' with
just the value of 'id', which is perhaps less risky than having "eval"
sitting in the middle of a filter.
Only problem is, Haml does not pass any variables ... the idea I had was
just like "render :partial => 'foobar', :locals => { :id => network.id}" ...
I want to to write something like this in Haml : (notice the { :id =>
network.id } near the filter name, and the '#{id} in the filtered text)
%span.name[network]= h(network.name)
:javascript{ :id => network.id }
new Ajax.InPlaceEditor('network_#{id}',
'/networks/set_network_name/#{id}');
This will allow me to use #{id} inside the filter text, and then the filter
itself will evaluate the filter text again ... and #{id} will be available
to it.
Please comment!, and ask questions if any,
Regards,
