Issue #12282 has been updated by briankung (Brian Kung). Agreed, this feature would be useful. I would like to essentially assert that all of the nodes along the path are found. To that end, I would suggest calling it something like `#fetch_path`: ``` ruby object = {foo: {bar: { baz: true}} object.fetch_path(:foo, :bar, :baz) #=> true object.fetch_path(:foo, :baz, :bar) #=> (irb):3:in 'Hash#fetch_path': key not found: :baz (KeyError) ``` ---------------------------------------- Feature #12282: Hash#dig! for repeated applications of Hash#fetch https://bugs.ruby-lang.org/issues/12282#change-114279 * Author: robb (Robb Shecter) * Status: Open ---------------------------------------- A new feature for your consideration: #dig! which is to #fetch as #dig is to #[]. For me and maybe many others, Hash#fetch is used much more than Hash#[]. And traversing multiple fetches isn't very convenient nor Ruby-like, e.g.: places.fetch(:countries).fetch(:canada).fetch(ontario). Here's how it would work: ~~~ruby places = { countries: { canada: true } } places.dig :countries, :canada # => true places.dig! :countries, :canada # => true places.dig :countries, :canada, :ontario # => nil places.dig! :countries, :canada, :ontario # => KeyError: Key not found: :ontario ~~~ Here's an implementation and tests: https://gist.github.com/dogweather/819ccdb41c9db0514c163cfdb1c528e2 -- https://bugs.ruby-lang.org/
