Issue #20882 has been updated by bkuhlmann (Brooke Kuhlmann). In case it's of interest, I use my [Refinements](https://alchemists.io/projects/refinements#_to_bool) gem for this. Example: ``` ruby using Refinements::String ENV["SOME_FEATURE"].to_bool # Either `true` or `false` depending on the resolved value. ENV.fetch("SOME_FEATURE", "0").to_bool # `false` ``` ---------------------------------------- Feature #20882: Provide Boolean(...) https://bugs.ruby-lang.org/issues/20882#change-110545 * Author: getajobmike (Mike Perham) * Status: Open ---------------------------------------- Ruby provides Integer(...) and Float(...) global methods to coerce values. Is there a similar method for Booleans? I'd like to do something like: ``` # ENV["SOME_FEATURE"] is unset Boolean(ENV["SOME_FEATURE"]) # => false # ENV["SOME_FEATURE"] is unset, but allow a default? Boolean(ENV["SOME_FEATURE"], true) # => true # explicitly disable ENV["SOME_FEATURE"] = "0" Boolean(ENV["SOME_FEATURE"], true) # => false # explicitly enable ENV["SOME_FEATURE"] = "1" Boolean(ENV["SOME_FEATURE"]) # => true ``` -- https://bugs.ruby-lang.org/
