credo v1.4.0-rc.1 Release Notes

Release Date: 2020-04-02 // about 4 years ago

    • 🚀 Credo's schema for pre-release names changes: There is now a . after the rc like in many other Elixir projects.

    • ➕ Add support for explaining checks (in addition to issues), i.e.

      $ mix credo explain Credo.Check.Design.AliasUsage

    • ➕ Add support for tags on checks

    Checks can now declare tags via the __using__ macro, i.e.

      defmodule MyCheck do
    use Credo.Check, tags: [:foo]

    def run(source_file, params) do
      #
    end
  end

    Tags can be used via the CLI switch --checks-with[out]-tag:

      # Only run checks tagged `:foo` during analysis
  $ mix credo --checks-with-tag foo

  # Exclude all checks tagged `:foo` from analysis
  $ mix credo --checks-without-tag foo
    • ➕ Add validation of check params in config

    If a param is not found, Credo checks for mispellings and suggests corrections:

      $ mix credo
  ** (config) Credo.Check.Design.AliasUsage: unknown param `fi_called_more_often_than`. Did you mean `if_called_more_often_than`?
