Issue #12282 has been updated by matz (Yukihiro Matsumoto). `fetch_path` is much better than `dig!` since this bang method is against our naming convention (if we have x and x!, a method with `!` (bang) should be more dangerous). At the same time, `_path` usually means file paths in Ruby, and possibly cause confusion, although **I** understand `path` here is totally valid. Matz. ---------------------------------------- Feature #12282: Hash#dig! for repeated applications of Hash#fetch https://bugs.ruby-lang.org/issues/12282#change-114317 * 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/
