Error when running functions in PrimalScript

[mbrouwer]

Hi,

I am evaluating script editors at the moment and one thing I ran into with PrimalScript is this, the problem is I dont know if its my inexperience with PowerShell or a "feature" or PrimalScript.

I have a script and it needs the ScriptDirectory compareble to the @SCRIPTDIR in KiX. I found a function and it works as long as I run it from PowerShell itself, when it runs from PrimalScript it gives me an error.

The code:

Code: Select all

function Get-ScriptDirectory
{
 $Invocation = (Get-Variable MyInvocation -Scope 1).ValueSplit-Path $Invocation.MyCommand.Path
}
       
function multiplynumbers
{
 $args[0] * $args[1]
}
       
multiplynumbers 446 282
       
Get-ScriptDirectory

The Error:

Code: Select all

125772
	
ERROR: Split-Path : Cannot bind argument to parameter 'Path' because it is null.

$MyInvocation is technically a PowerShell Host feature, not a PowerShell feature. So it gets set by PowerShell.exe rather than the engine. As such it is a bit undocumented from the technical side.
We are aware of the problem and working on adding it to the PrimalScript host that runs scripts directly.
