Modules in PowerShell v.2 can declare which functions, variables, aliases etc. are public and visible to the caller and which ones are hidden. With a trick, you can also access hidden members. Let's assume you have saved the following module as example.psm1:
$internal = 1
$external = 2
function Test-Function1 {
"I am function 1"
}
$external = 2
function Test-Function1 {
"I am function 1"
}
function Test-Function2 {
"I am function 2"
}
Export-ModuleMember –function Test-Function1 -Variable external
You need to import this module with a reference to gain access to hidden members:
$module = Import-Module path_to_module\example.psm1 -passThru
Now, you can submit a script block to the module, which executes in its private context and has access to all members, regardless of what Export-ModuleMember has declared public:
& $module { "The hidden variable INTERNAL contains: $internal }
