AvoidGlobalFunctions

Severity Level: Warning

Description

Globally scoped functions override existing functions within the sessions with matching names. This name collision can cause difficult to debug issues for consumers of modules.

To understand more about scoping, see Get-Help about_Scopes.

How

Use other scope modifiers for functions.

Example

Wrong

function global:functionName {}

Correct

function functionName {}
