Powershell support?

[nbfritch]

I love fnox. Recently I wanted to introduce it to a cross-platform project where a few developers use powershell.

Currently I get around the lack of powershell support by using this helper function that (ab)uses fnox's nushell support:

function LoadFnox {
  [CmdletBinding()]
  param()
  
  $jsonText = (& fnox hook-env -s nu | Out-String).Trim()
  if ($jsonText -eq '') {
    throw 'Error running fnox'
  }

  $payload = $jsonText | ConvertFrom-Json -AsHashTable
  if (-not $payload.ContainsKey('set')) {
    throw 'Error, fnox returned invalid format'
  }
  
  foreach ($entry in $payload['set'].GetEnumerator()) {
    $name = [string]$entry.Key
    $value = if ($null -eq $entry.Value) { '' } else { [string]$entry.Value }
    Set-Item -Path "Env:$name" -Value $value
  }
}

I know mise and fnox are similar in architecture and mise supports powershell. As far as I can tell, in fnox, the shell specific crate is only used in the activate/deactivate commands (not calling the providers).

Are there any other things that might block native powershell support?

no blockers I'm aware of

I had some time to work on this. It ended up being simpler than I expected. I opened a PR to add support for powershell: #421

And support has been merged in v1.21.0!
