如果你不介意失去制表符补全（这应该没关系，因为你不应该交互地运行函数），一个可能的解决方案是有一个脚本，调用你的函数脚本，执行所需的函数，但只有当它是通过脚本运行。
funcs.ps1:

Param(
    [parameter(Position=0)]$FunctionName,
    [parameter(Position=1,ValueFromRemainingArguments= $true)]$FunctionArgs
)
. $pwsh\internal\subfuncs.ps1
if($MyInvocation.CommandOrigin -eq "Runspace"){Write-Warning 'Cannot be run interactively';return}
&$FunctionName @FunctionArgs

然后将所有函数移到subfuncs.ps1中。然后你在你的个人资料中调用它，比如：

$pwsh\internal\funcs.ps1 MyPrivateFunction

或者，如果你不喜欢按名称调用脚本，你可以创建一个函数来调用它，并对调用者函数进行把关：

Function Call-Function{
    if($MyInvocation.CommandOrigin -eq "Runspace"){
        Write-Warning 'Cannot be run interactively'
        return
    }
    & $pwsh\internal\funcs.ps1 @args
}

然后在你的脚本中只写Call-Function myprivatefunction，或者如果太长的话，把函数名减少到cf或者别的什么，它就是cf myprivatefunction。

我终于做到了！包括使用化名。

就是这样！
您不能直接在终端中调用Start-WindowsTerminalInDirectory。
