Question

我在nsis卸载程序中编写SetSilent，但是当我从cmd调用它时，它将在新的cmd窗口中打开。我需要在当前的cmd中运行卸载。你能帮我吗？

为此，我更喜欢将NSIS构建为控制台程序，但是可以允许GUI程序写入现有的控制台窗口。这种方法的缺点是输入光标不会随输出一起移动，因此用户可能会在安装完成后输入cls，并且您必须将此事实通知他们。为了获得更多的荣誉，我还添加了DetectConsole函数来自动确定是否从命令行调用了NSIS，但是您需要为GetProcessInfo包含以下标头： https://nsis.sourceforge.io/Get_process_info

但是在任何情况下，都有可能出现以下情况。您可以将DetailPrint包裹在一个也可以执行StdOutPrint的宏中，并使用nsExec :: ExecToStack：https://nsis.sourceforge.io/NsExec_plug-in和StdOutPrint堆栈内容（尽管您可能希望使用NSIS长字符串构建来捕获更多详细输出））。

如果您需要使用/ S参数打开一个新的命令窗口（即使没有从命令行调用（嘈杂的寂静声），则在必要时也可以），然后用“; $ {OrIf} $ {Silent} “和”; SetSilent无声“
