CodeStyle

Shared Credo policy and custom checks for Elixir codebases.

Installation

Add code_style to a consuming Mix project:

{:code_style, "~> 0.1.0", only: [:dev, :test], runtime: false}

Then load the Credo plugin in .credo.exs:

%{
  configs: [
    %{
      name: "default",
      plugins: [{CodeStyle, []}]
    }
  ]
}

The plugin registers the shared Credo policy, ExSlop checks, migration safety, and the custom checks below.

CodeStyle.Check.Design.NoDatabaseConstraints flags business-logic column options in Ecto migration table blocks.

CodeStyle.Check.Warning.RepoInsideLoop flags direct Repo.* calls inside Enum, Stream, and for loop bodies where the code is likely to create N+1 query behavior.

Run the package checks with Mix:

mix check
