If psdrive was created in a previous raw, it won't be found.

I created such test page:
!|script|
|eval|mkdir c:\test|
|eval|1..5 > c:\test\file1.txt|

!|script|
|eval|New-PSDrive -PSProvider FileSystem -name test -root c:\test;$res1 = gc test:file1.txt -last 1|
|check|eval|$res1|5|

!|script|
|eval|New-PSDrive -PSProvider FileSystem -name test -root c:\test|
|eval|$res2=gc test:file1.txt -last 1|
|check|eval|$res2|5|

the first check is successful, but second one is not. Output Captured returns an error:
gc : Cannot find drive. A drive with the name 'test' does not exist.

Do you think it is an issue of PowerSlim? I don't think so.... It is bug tracker but not discussion board.
Konstantin, could you create Google group for such discussions?

[mikeplavsky]

IMHO we can discuss it here. It is a triage. Nothing bad with it.

[abuyanov]

IMHO it is PowerSlim issue.
I would be very grateful if you could explain why the psdrive that I have created is not available at next raw. I hope it will help me to better understand PowerSlim.

Alexander, I agree with you, seems like a PowerSlim issue! Looking into it right now!

[mikeplavsky]

I have changed the last table:

!|script|
|check|eval|$d = New-PSDrive -PSProvider FileSystem -name test1 -root c:\test;$res2=gc test1:file1.txt -last 1||
|check|eval|$res2|5|
|check|eval|$res2=gc test1:file1.txt -last 1||
|check|eval|$res2|5|

The second raw is green.
My guess is by some reason "test1" drive is not visible in the global namespace.

[mikeplavsky]

I see such code in PowerSlim and imho that's the reason why.

if($s.StartsWith('function',$true,$null)){Set-Variable -Name Script__ -Value ($s -replace 'function\s+(.+)(?=\()','function global:$1') -Scope Global}
else{Set-Variable -Name Script__ -Value ($s -replace '\$(\w+)(?=\s*=)','$global:$1') -Scope Global}

It looks like w/o such code variables are local to the script.

[mikeplavsky]

Alexander, here is the temporary fix for you:

!|script|
|check|eval|New-PSDrive -PSProvider FileSystem -name test1 -root c:\test -Scope Global||
|check|eval|$res2=gc test1:file1.txt -last 1||
|check|eval|$res2|5|

See this parameter -Scope Global
Is it ok for now?

[abuyanov]

Mike, thanks a lot for explanation.
