No Call

Avoid calls to specific functions.

Rationale

Some functions may be discouraged due to deprecation, known performance issues, unsafe side effects, or because better alternatives exist. This rule serves as a centralized and customizable enforcement point, allowing developers to prevent the use of problematic or non-idiomatic functions and maintain consistency across a codebase.

Options

• no_call_functions :: [{module() | '_', function() | '_', arity() | '_'} | {module() | '_', function() | '_'}]

  • default: []

'_' wildcards was added in 3.2.0.

Example configuration

{elvis_style, no_call, #{no_call_functions => []}}
