OptimumCredo.Check.Refactor.WithElseManyClauses (OptimumCredo v0.5.0)

Basics

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

Explanation

A with with a long else usually means inner calls return ambiguous errors. Return exact {:error, reason} values from the inner functions so the else shrinks or disappears. Opt-in, low priority; counts clauses only.

Check-Specific Parameters

Use the following parameters to configure this check:

:min_else_clauses

Smallest else clause count that is reported.

This parameter defaults to 3.

General Parameters

Like with all checks, general params can be applied.

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