chsh / pathable_hash.rb
Created May 29, 2011 16:29
Add Hash#path method to lookup deep structured hash value.
# pathable_hash.rb
# Add Hash#path method to lookup deep stuructured hash value.
# e.g)
# h0 = {a: {b: {c: 1}}}
# h0.path '/a/b/c' => 1
# h0.path 'a/b/c' => 1 # heading slash has no meaning.
# h1 = {a: {b: [1,2,{c: 3}]}
# h1.path '/a/b[2]/c' => 3 # [\d] means picking up array item.
# path syntax is inspired by xpath, but not same. :-)
