<# .SYNOPSIS Dynamically Defines Aliases .DESCRIPTION Can Dynamically Define Aliases. When uses in a parameter attribute, -Aliases will define a list of aliases. When used with a variable, [Aliases] will Set-Alias on each value in the variable. .EXAMPLE { $aliases = "Foo", "Bar", "Baz" [Aliases(Command="Get-Process")]$aliases } | .>PipeScript .Example { param( [Aliases(Aliases={ ([char]'a'..[char]'z') })] [string] $Drive ) } | .>PipeScript #> [CmdletBinding(DefaultParameterSetName='AliasNames')] [Alias('SmartAlias','DynamicAlias')] param( # A list of aliases [Parameter(Mandatory,ParameterSetName='AliasNames')] [Alias('Alias')] [string[]] $Aliases, # If provided, will prefix each alias [string] $Prefix, # If provided, will add a suffix to each alias [string] $Suffix, # The command being aliased. This is only required when transpiling a variable.
