Re: [haml] Using tap with Haml to create scoped local variables
I know, but in ERB I prefer using #tap to scope local variable - this way it's only available inside the block where it's needed and not in the whole view. Usually the code can be simply refactored into a helper method, but sometimes it was useful. Thanks, Szymon -- You received this message because you are subscribed to the Google Groups Haml group.

Re: [haml] Using tap with Haml to create scoped local variables
I haven't seen this behavior with tap and HAML. For me, it works as you expect: it doesn't output the tapped variable. Are you sure you used a '-' rather than a '='? :brad On Thu, Mar 17, 2011 at 5:51 AM, Szymon Nowak szi...@gmail.com wrote: I know, but in ERB I prefer using #tap to scope local variable - this way it's only available inside the block where it's needed and not in the whole view.

[haml] Using tap with Haml to create scoped local variables
Hey,
in ERB it was possible to use tap to not repeat some calculations, e.g.:
% Model.some_complex_query.tap do |result| %
%= something if result.size 0 %
% result.each {} %
% end %
and so on...
When I try similar thing it in Haml it displays the value of the tapped
object after executing the block.
- string.tap do |s|
-# nothing here
will display string, because it simply executes the code and #tap returns
the original object after executing the block. Is there a way to get similar
behavior as in ERB?
Cheers,
Szymon

You don't need a block for this, you just need a local variable.
