Variable Scoping Quirk

[flytape8490]

When invoke-epstemplate is called from within a function, it only sees variables defined outside the function unless they are specifically added with the Binding hashtable.

eps.txt:

<%= $value -%>

PowerShell script

Import-Module EPS
$value = "Outside"

Function FunctionTest
{
    $value = "Inside"
    Write-Host "From a function, the value of `$value is $value"
    Write-Host "From a function, the result from invoke is $(Invoke-EpsTemplate -Path "eps.txt")"
    Write-Host "From a function, the result from invoke WITH BINDING is $(Invoke-EpsTemplate -Path "eps.txt" -Binding @{"value"=$value})"
}

Write-Host "The value of `$value is $value"
Write-Host "The value from invoke is $(Invoke-EpsTemplate -Path "eps.txt")"

FunctionTest

Results:

> The value of $value is Outside
> The value from invoke is Outside
> From a function, the value of $value is Inside
> From a function, the value from invoke is Outside
> From a function, the value from invoke WITH BINDING is Inside

Expected results:

> The value of $value is Outside
> The value from invoke is Outside
> From a function, the value of $value is Inside
> From a function, the value from invoke is Inside
> From a function, the value from invoke WITH BINDING is Inside
