View Source Credo.Check.Readability.ParenthesesOnZeroArityDefs (Credo v1.7.2-rc.4)
This check has a base priority of low
and works with any version of Elixir.
Explanation
Either use parentheses or not when defining a function with no arguments.
By default, this check enforces no parentheses, so zero-arity function and macro definitions should look like this:
def summer? do
# ...
end
If the :parens
param is set to true
for this check, then the check
enforces zero-arity function and macro definitions to have parens:
def summer?() do
# ...
end
Like all Readability
issues, this one is not a technical concern.
But you can improve the odds of others reading and liking your code by making
it easier to follow.
Check-Specific Parameters
There are no specific parameters for this check.
General Parameters
Like with all checks, general params can be applied.
Parameters can be configured via the .credo.exs
config file.
