Merges self with another hash, recursively.
This code was lovingly stolen from some random gem: gemjack.com/gems/tartan-0.1.1/classes/Hash.html
Thanks to whoever made it.
# File lib/jekyll/core_ext.rb, line 8 def deep_merge(hash) target = dup hash.keys.each do |key| if hash[key].is_a? Hash and self[key].is_a? Hash target[key] = target[key].deep_merge(hash[key]) next end target[key] = hash[key] end target end
Read array from the supplied hash favouring the singular key and then the plural key, and handling any nil entries.
+hash+ the hash to read from +singular_key+ the singular key +plural_key+ the plural key
Returns an array
# File lib/jekyll/core_ext.rb, line 30 def pluralized_array(singular_key, plural_key) hash = self if hash.has_key?(singular_key) array = [hash[singular_key]] if hash[singular_key] elsif hash.has_key?(plural_key) case hash[plural_key] when String array = hash[plural_key].split when Array array = hash[plural_key].compact end end array || [] end
