function Import-Macro { <# .Synopsis Imports Macros from a module .Description Imports Macros that are defined in a module. .Notes Modules can define Macros by adding a PoshMacros property to PrivateData, or to the module itself. The key of each Macro will be treated as it's name, and the value should be a hashtable of input parameters or a string. If the value is a string, the macro will be an alias. Otherwise, the macro will be defined using the input parameter hashtable. .Link Add-Macro .Link Export-Macro #> [OutputType()] param( # The name of the module [Parameter(Mandatory,ValueFromPipelineByPropertyName)] [string] $Name, # If set, will output the created macro module.
