Description

• install oh-my-posh in PowerShell 7
• run --install completion on a Typer app
• inspect the contents of Users/<user>/Documents/PowerShell/Microsoft.PowerShell_profile.ps1

oh-my-posh init pwsh | Invoke-ExpressionImport-Module PSReadLine
Set-PSReadLineKeyHandler -Chord Tab -Function MenuComplete
$scriptblock = {
    param($wordToComplete, $commandAst, $cursorPosition)
    $Env:_FAWLS_COMPLETE = "complete_powershell"
    $Env:_TYPER_COMPLETE_ARGS = $commandAst.ToString()
    $Env:_TYPER_COMPLETE_WORD_TO_COMPLETE = $wordToComplete
    fawls | ForEach-Object {
        $commandArray = $_ -Split ":::"
        $command = $commandArray[0]
        $helpString = $commandArray[1]
        [System.Management.Automation.CompletionResult]::new(
            $command, $command, 'ParameterValue', $helpString)
    }
    $Env:_FAWLS_COMPLETE = ""
    $Env:_TYPER_COMPLETE_ARGS = ""
    $Env:_TYPER_COMPLETE_WORD_TO_COMPLETE = ""
}
Register-ArgumentCompleter -Native -CommandName fawls -ScriptBlock $scriptblock

It sorta looks like the installation of completion correctly appends to the file, but it doesn't open with a newline. This is invalid PS syntax. It is corrected by simply prefixing the completion script with a newline:

oh-my-posh init pwsh | Invoke-Expression
Import-Module PSReadLine
Set-PSReadLineKeyHandler -Chord Tab -Function MenuComplete
$scriptblock = {
    param($wordToComplete, $commandAst, $cursorPosition)
    $Env:_FAWLS_COMPLETE = "complete_powershell"
    $Env:_TYPER_COMPLETE_ARGS = $commandAst.ToString()
    $Env:_TYPER_COMPLETE_WORD_TO_COMPLETE = $wordToComplete
    fawls | ForEach-Object {
        $commandArray = $_ -Split ":::"
        $command = $commandArray[0]
        $helpString = $commandArray[1]
        [System.Management.Automation.CompletionResult]::new(
            $command, $command, 'ParameterValue', $helpString)
    }
    $Env:_FAWLS_COMPLETE = ""
    $Env:_TYPER_COMPLETE_ARGS = ""
    $Env:_TYPER_COMPLETE_WORD_TO_COMPLETE = ""
}
Register-ArgumentCompleter -Native -CommandName fawls -ScriptBlock $scriptblock

Should Typer be opening with a newline, just in case? FYI, oh-my-posh is widely used 😄 https://github.com/JanDeDobbeleer/oh-my-posh
