I give you all, probably the most unused function on the planet. The “Make one-liner”!

It’s probably not even close to “Complete” but it is easy to add exceptions on where to format.

Function Main{
    $ScriptString = Get-Content [enter powershell script path here]
    Make-Oneliner $ScriptString
}

Function Make-Oneliner{
    Param([Array]$array)
    [string]$OneLiner = @()
    Foreach($Line1 in $array){
    
    $Line1 = $Line1.Split("#")[0]
    $Line1 = $Line1.Trim()
    Foreach($Line in $Line1){
        #Parse and add ;
            If(
                ($line.EndsWith("`{")) -or
                ($line.EndsWith("`;")) -or
                ($line.EndsWith("`(")) -or
                ($line.EndsWith("`|")) -or
                ($line.EndsWith("`]"))
            ){
                    $OneLiner += $Line
            }
            Elseif($line.EndsWith("`'")){
                if(($Line.Split("`'").Count % 1) -eq 0){
                    $Line = $Line + "`;"
                    $OneLiner += $Line
                    }
            }
            Elseif($line.EndsWith("`"")){
                if(($Line.Split("`"").Count % 1) -eq 0){
                    $Line = $Line + "`;"
                    $OneLiner += $Line
                    }
            }
            Elseif($Line.StartsWith("#")){
                # do nothing
            }
            Else{
                $Line = $Line + "`;"
                $OneLiner += $Line
            }
        }
    }
    # Cleanup inappropriate ";".
    $OneLiner = $OneLiner.Replace(';)',')').Replace(',;',',').Replace(';;',';').Replace(';;',';')

    # Cleanup inappropriate ";" on words using insensitive replace methods.
    $OneLiner = $OneLiner -ireplace '};else','}else'
    $OneLiner = $OneLiner -ireplace '};catch','}catch'
    $OneLiner = $OneLiner -ireplace '};finally','}finally'

    Return $OneLiner
