Bylaw.Credo.Check.Elixir.NoThen (bylaw_credo v0.1.0-alpha.1)

Basics

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

Explanation

Prefer explicit control flow over then/2.

Examples

Avoid:

  value
  |> transform()
  |> then(&{:ok, &1})

  then(value, &{:ok, &1})

Prefer:

  value =
    value
    |> transform()

  {:ok, value}

Notes

This check uses static AST analysis, so it favors clear source-level patterns over runtime behavior.
