During refactoring it would be quite handy just to copy part of HAML template and paste it to helper's code. Currently in such cases 1) I have to rewrite that part of view from scratch 2) I have to use that verbose syntax like content_tag or haml_tag.
I know that it's possible to define partials with HAML systax that will serve as helper. Though 1) as for me it's inconvinient to create a separate file for each small tiny function 2) invocation syntax for partial is quite verbose.
Ideally i'd like my *_helper class to look like this:
- def some_helper(*its_args)
.some_class
= some_ruby_expression
%some_tag#some_id
- another_expression do
etc
or at least like this:
define_haml_helper :some_helper, [:arg1, :arg2], %{
.some_class
= some_ruby_expression
%some_tag#some_id
- another_expression do
etc
}
Is there a plugin that solves my issue?
Alternatively, maybe you can describe how do you refactor HAML snippets to reusable elements (helpers/functions/partials/builders/etc)?
From the reference :
def render_haml(code)
engine = Haml::Engine.new(code)
engine.render
end
This initiates a new Haml engine and renders it.
Haml now has a capture_haml
method that you can use to accomplish this.
def some_helper
capture_haml do
.some_class
= yield
#some-code-after
end
end
some_helper do
%h1 Hello World
end
=> <div class="some_class">
<h1>Hello World</h1>
</div>
<div id="some-code-after"></div>
Here is a link with more info on capture_haml
: http://haml.info/docs/yardoc/Haml/Helpers.html#capture_haml-instance_method
If all you are after is a method for small reusable snippets, how about partials with local variables? http://guides.rubyonrails.org/layouts_and_rendering.html#using-partials
