View Source Credo.Check.Consistency.UnusedVariableNames (Credo v1.7.5)
Basics
This check is disabled by default.
Learn how to enable it via
.credo.exs
.
This check has a base priority of high
and works with any version of Elixir.
Explanation
Elixir allows us to use _
as a name for variables that are not meant to be
used. But it’s a common practice to give these variables meaningful names
anyway (_user
instead of _
), but some people prefer to name them all anonymously (_
).
A single style should be present in the same codebase.
