Recursively Setting Deep Hash Value
I’ve always wanted to be able to do something like:
my_hash = {}
my_hash["Cloud"]["Stats"]["Strength"] = 100
p my_hash # => {"Cloud"=>{"Stats"=>{"Strength"=>100}}}</pre>
So I whipped up this small code and now I can! Metaprogramming wins again!

Alternatively,
Hash.new { |h,k| h[k] = Hash.new(&h.default_proc) }@sutto your version does’nt work with ruby 1.8.7 (at least not for me). but 1.9.2 works fine. nice solution, both of you.
Both solutions are nice. But I was wondering if you are familiar with ruby facets. It’s a very cool Ruby library and has a solution for this problem. You can take a look to http://rubyworks.github.com/facets/doc/api/core/Hash.html for the autonew method.
didn’t you already post it, http://www.rubyflow.com/items/5667-recursively-setting-deep-hash-value
