LexCredo.Check.Warning.NoPipeIntoCase (LexCredo v0.1.0)

Basics

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

Explanation

Do not pipe into case expressions.

Assign intermediate results to a variable and pass it to case directly. Piping into case is hard to read and can obscure the subject of the match.

# BAD
build_post(attrs)
|> store_post()
|> case do
  {:ok, post} -> post
  {:error, _} -> nil
end

# GOOD
changeset = build_post(attrs)
case store_post(changeset) do
  {:ok, post} -> post
  {:error, _} -> nil
end
