命令行提示原型

Module MainPrompt
Public Const PromptSymbol As String = "TLA > "
Public Const ApplicationTitle As String = GetType(Project.BaseClass).Assembly.FullName
REM Or you can use a custom string
REM Public Const ApplicationTitle As String = "Short name of the application"

该原型生成一个基本的命令行解释器。

它会自动获取应用程序名称和版本以与用户进行通信。对于每个输入行，它识别命令和任意参数列表，所有参数都用空格分隔。

作为一个基本示例，此代码了解 ver ， quit 和 exit 命令。

参数 Project.BaseClass 是项目的一个类，其中设置了程序集详细信息。
