View Source Credo.Check.Refactor.RedundantWithClauseResult (Credo v1.7.2-rc.4)
This check has a base priority of high
and works with any version of Elixir.
Explanation
with
statements are useful when you need to chain a sequence
of pattern matches, stopping at the first one that fails.
If the match of the last clause in a with
statement is identical to the expression in the
in its body, the code should be refactored to remove the redundant expression.
This should be refactored:
with {:ok, map} <- check(input),
{:ok, result} <- something(map) do
{:ok, result}
end
to look like this:
with {:ok, map} <- check(input) do
something(map)
end
