NSIS-在命令行安装期间打印到提示符

NSIS是一个GUI程序,实际上不具备向stdout写入数据的能力。

在XP和更高版本上,您可以使用系统插件执行此操作:

System::Call 'kernel32::GetStdHandle(i -11)i.r0' 
System::Call 'kernel32::AttachConsole(i -1)' 
FileWrite $0 "hello" 

在<XP上,没有AttachConsole,您需要在这些系统上调用AllocConsole(可能会打开一个新的控制台窗口)

编辑: 如果父进程中没有

!include LogicLib.nsh
System::Call 'kernel32::GetStdHandle(i -11)i.r0' 
System::Call 'kernel32::AttachConsole(i -1)i.r1' 
${If} $0 = 0
${OrIf} $1 = 0
 System::Call 'kernel32::AllocConsole()'
 System::Call 'kernel32::GetStdHandle(i -11)i.r0' 
${EndIf}
FileWrite $0 "hello$\n" 

但这真的没有什么意义吗?处理完毕,您最好在没有控制台时打开一个消息框

!include LogicLib.nsh
StrCpy $9 "USAGE: Hello world!!" ;the message
System::Call 'kernel32::GetStdHandle(i -11)i.r0' ;try to get stdout
System::Call 'kernel32::AttachConsole(i -1)i.r1' ;attach to parent console
${If} $0 <> 0
${AndIf} $1 <> 0
 FileWrite $0 "$9$\n" 
${Else}
 MessageBox mb_iconinformation $9
${EndIf}

!include LogicLib.nsh
StrCpy $9 "USAGE: Hello world!!" ;the message
System::Call 'kernel32::AttachConsole(i -1)i.r0' ;attach to parent console
${If} $0 != 0
 System::Call 'kernel32::GetStdHandle(i -11)i.r0' ;console attached -- get stdout
 FileWrite $0 "$9$\n" 
${Else}
 ;no console to attach -- show gui message
 MessageBox mb_iconinformation $9
${EndIf}

首先连接控制台,然后获取标准手柄。在连接之前,句柄可能(通常会)无效。
