First of all i'm sorry if i missed a similar topic, tried searching but couldnt find it.

I have a facter file that outputs extra characters. If I were to run the query individually i get my desired output, but if i include puppet formats it has extra characters garbage;

My code is as per below, to query via wmi a server's domain role;

Facter.add(:w2k8_systemrole) do
  confine :kernel => :windows
  setcode do
    value = "unknown"
        value = Facter::Core::Execution.exec('C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -ExecutionPolicy remotesigned -Command "& {(Get-WmiObject win32_computersystem).DomainRole}"')
       if value != "*"
         value = value
         value = "DomainRole is not defined for the system."

instead of "2" i get ƒ^cƒ-ƒ"?2. Please help, thanks.

Regards, Kuro

I have no idea, what your command's supposed to do, but it returns a string, which you may value.sub(/x$/, '') https://ruby-doc.org/core/String.html#method-i-sub where `x` is your extra character (at the end of the string [dollar-sign]). This is more of a quick'n'dirty work-around, though.

Hi Kai,

Thats a great workaround. I added this line to filter the output:

value.sub(/^\S\S\S/, '')

Will just go with this in the meantime.

You may want to try `value.sub(/\D/, '')` which will replace all non-digits (assuming the answer is always a digit) regardless of any changes in non-printable formatting.

No, this is not a quote-unquote great workaround. You update your software, it's output changes, and your fact's value silently breaks.
