fetch_in¶ ↑

adds fetch_in and store_in methods to Hash and Array which allow for easy fetching and storing of values in nested associative structures

fetch values from nested associative structures without worrying about testing for nils

h={:foo=>[{:bar=>1}]}
h.fetch_in(:foo, 0, :bar)
=> 1
h.fetch_in(:bar, 0, :foo)
=> nil

store values in a nested associative structure, automatically creating new levels in the structure if required

h={}
h.store_in(:foo, :bar, 2)
h
=>{:foo=>{:bar=>2}}

h=[]
h.store_in(1,2,3)
h
=>[nil,[nil,nil,3]]

gem install fetch_in

• Fork the project.

• Make your feature addition or bug fix.

• Add tests for it. This is important so I don’t break it in a future version unintentionally.

• Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)

• Send me a pull request. Bonus points for topic branches.
