Question

This question is for very very specific case, where I may change params. This is not a part of any rails app.

params is {:email => " ab", :xyz => " ", :opq => nil}
I run following :

params.each{|_, v| v.strip! if v}
params.keep_if{|_, v| v.length > 0 if v}

to get params as
{:email => "ab"}

is there anyway to merge above two lines into one?

ruby-1.9.3-p125 :011 > params ={:email => " ab", :xyz => " ", :opq => nil}
 => {:email=>" ab", :xyz=>" ", :opq=>nil} 
ruby-1.9.3-p125 :012 > params.reject! { |_, v| !v || v.strip!.length == 0 }
 => {:email=>"ab"}
