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.
No fiting. IS always goes at the start of names for booleans you are correct
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
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
does ‘?’ have type definition in elixir or this is generally agreed design pattern?
We do this in Ruby all the time, we just prefer methods over variables, usually.
def authorized?
current_user&.authorized?
end
