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.

Explanation

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

# snake_case

def handle_incoming_message(message) do
end

# not snake_case

def handleIncomingMessage(message) 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.

Configuration parameters

Use the following parameters to configure this check:

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

    Defaults to false

Like with all checks, general params can be applied.

Parameters can be configured via the .credo.exs config file.
