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_in

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_in

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]]

Install

gem install fetch_in

Note on Patches/Pull Requests

  • 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.
