Copilot CLI in PowerShell

About Copilot CLI.md

We are, for now, just using the official github copilot CLI, but they didn't really have hooks for PowerShell, so I wrote a few functions to implement it.

It works great, as you can see:

Copilot.psm1

function NewTemporaryScript {
    [IO.Path]::ChangeExtension(([IO.Path]::GetTempPath() + [IO.Path]::GetRandomFileName()), "ps1")
}
function InvokeTemporaryScript {
    [CmdletBinding()]
    param($ScriptPath)
    if (Test-Path $ScriptPath) {
        . $ScriptPath
        Remove-Item $ScriptPath
    }
}

function Request-CopilotAssist {
    [CmdletBinding()]
    [Alias('??','rqa')]
    param([Parameter(ValueFromRemainingArguments)][string[]]$args)
    $TmpFile = NewTemporaryScript
    github-copilot-cli what-the-shell ('use powershell to ' + $args) --shellout $TmpFile
    InvokeTemporaryScript $TmpFile
}

function Request-CopilotGitAssist {
    [CmdletBinding()]
    [Alias('git?','rqga')]
    param([Parameter(ValueFromRemainingArguments)][string[]]$args)
    $TmpFile = NewTemporaryScript
    github-copilot-cli git-assist $args --shellout $TmpFile
    InvokeTemporaryScript $TmpFile
}
function Request-CopilotGitHubAssist {
    [CmdletBinding()]
    [Alias('gh?','rqgha')]
    param([Parameter(ValueFromRemainingArguments)][string[]]$args)
    $TmpFile = NewTemporaryScript
    github-copilot-cli gh-assist $args --shellout $TmpFile
    InvokeTemporaryScript $TmpFile
}
