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

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

Explanation

Provide module parts in a required order.

# preferred

defmodule MyMod do
  @moduledoc "moduledoc"
  use Foo
  import Bar
  alias Baz
  require Qux
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:

• order: List of atoms identifying the desired order of module parts.

  Supported values are:

  • :moduledoc - @moduledoc module attribute
  • :shortdoc - @shortdoc module attribute
  • :behaviour - @behaviour module attribute
  • :use - use expression
  • :import - import expression
  • :alias - alias expression
  • :require - require expression
  • :defstruct - defstruct expression
  • :opaque - @opaque module attribute
  • :type - @type module attribute
  • :typep - @typep module attribute
  • :callback - @callback module attribute
  • :macrocallback - @macrocallback module attribute
  • :optional_callbacks - @optional_callbacks module attribute
  • :module_attribute - other module attribute
  • :public_fun - public function
  • :private_fun - private function or a public function marked with @doc false
  • :public_macro - public macro
  • :private_macro - private macro or a public macro marked with @doc false
  • :callback_impl - public function or macro marked with @impl
  • :public_guard - public guard
  • :private_guard - private guard or a public guard marked with @doc false
  • :module - inner module definition (defmodule expression inside a module) Notice that the desired order always starts from the top. For example, if you provide the order ~w/public_fun private_fun/a, it means that everything else (e.g. @moduledoc) must appear after function definitions. Defaults to [:shortdoc, :moduledoc, :behaviour, :use, :import, :alias, :require]

• ignore: List of atoms identifying the module parts which are not checked, and may therefore appear anywhere in the module. Supported values are the same as in the :order param.

  Defaults to []

Like with all checks, general params can be applied.

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