Credo.Check.Warning.OperationOnSameValues (Credo v1.5.0) View Source

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

Explanation

Operations on the same values always yield the same result and therefore make little sense in production code.

Examples:

x == x  # always returns true
x <= x  # always returns true
x >= x  # always returns true
x != x  # always returns false
x > x   # always returns false
y / y   # always returns 1
y - y   # always returns 0

In practice they are likely the result of a debugging session or were made by mistake.

Configuration parameters

There are no specific parameters for this check.

Like with all checks, general params can be applied.

Parameters can be configured via the .credo.exs config file.
