Credo.Check.Readability.FunctionNames (Credo v1.5.0) View Source

This check has a base priority of high and works with any version of Elixir.


Function, macro, and guard names are always written in snake_case in Elixir.

# snake_case

def handle_incoming_message(message) do

# not snake_case

def handleIncomingMessage(message) do

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.

Configuration parameters

  • allow_acronyms: Allows acronyms like HTTP or OTP in function names.
