    First one are method name, second one are status name.

    
    def open_file_dialog(self):
           self.dialog_file_open = True
           pass
    
    

    Yoda level preference war.

      I tend to add is to booleans toreally differentiate between a method name and a status.

      def open_file_dialog(self):
          self.dialog_file_is_open = True
          pass
      

      That way, it’s easier for my dumb brain to spot which is which at a glance.

            that works for 2 word names eg is_open or is_file, but in this case is_dialog_file_open is structured like a question, while dialog_file_is_open is structured like a statement

              Doesn’t matter, the point is that, if it starts with “is” then you automatically know it’s a boolean.

              It still works. is_this_thing_some_thingy. Is is just a prefix for if the suffix returns true/false.

        In Elixir, we mark statuses by using a question mark at the end of the variable name. Something like this:

        authorized? = user |> get_something() |> ensure_authorized?()
        

        I like this better than the is_ prefix

            If it’s like Lisp, then ? is just part of the symbol and doesn’t have any special syntatic meaning. In different Lisps it’s also convention to end predicate names with a ? or with P (p for predicate)

            We do this in Ruby all the time, we just prefer methods over variables, usually.

            def authorized?
              current_user&.authorized?
            end

              I’m a principal backend engineer routinely writing Ruby for my day job, so I’m familiar, lol. But you can’t do it for local variables and that just sucks. Definitely a +1 for Elixir.
