View Source Credo.Check.Consistency.SpaceInParentheses (Credo v1.6.4)

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.

Check-Specific 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.

This parameter defaults to false.

General Parameters

Like with all checks, general params can be applied.

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