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

Explanation

Don't use spaces after (, [, and { or before }, ], and ). This is the preferred way, although other styles are possible, as long as it is applied consistently.

# preferred

Helper.format({1, true, 2}, :my_atom)

# also okay

Helper.format( { 1, true, 2 }, :my_atom )

While this is not necessarily a concern for the correctness of your code, you should use a consistent style throughout your codebase.

Configuration parameters

Use the following parameters to configure this check:

• allow_empty_enums: Allows [], %{} and similar empty enum values to be used regardless of spacing throughout the codebase.

  Defaults to false

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