NSIS-使用命令行参数跳过某些对话框

Question

有没有办法让NSIS安装程序跳过某些对话框？

它有这些命令行参数，

/S、/NCRC和/D=dir

虽然/S和/NCRC可以用于静默和无人参与模式，但是否有命令行参数可以使安装程序跳过安装程序中的某些对话框并显示对话框的其余部分？例如跳过"欢迎"对话框和接下来的两个对话框，转到第四个对话框。

/S、/NCRC和/D=是唯一具有内置支持的安装程序参数，其他任何参数都必须自己处理。

在页面预回调中调用Abort可以跳过页面。也可以向前跳转特定数量的页面。GetOptions宏可用于解析命令行。

OutFile Test.exe
RequestExecutionLevel user
InstallDir $Temp
!include LogicLib.nsh
!include FileFunc.nsh
Page License LicPre
Page Components CmpPre
Page Directory "" DiShow
Page InstFiles
Var SkippedL
Var SkippedC
!macro AbortIfCmdlineParam Switch Var
${GetParameters} $0
ClearErrors
${GetOptions} $0 "${Switch}" $0
${IfNot} ${Errors}
${If} ${Var} = 0
StrCpy ${Var} 1
Abort
${EndIf}
${EndIf}
!macroend
Function LicPre
!insertmacro AbortIfCmdlineParam "/SkipL" $SkippedL
FunctionEnd
Function CmpPre
!insertmacro AbortIfCmdlineParam "/SkipC" $SkippedC
FunctionEnd
Function DiShow
# Disable back button if both pages skipped, this is optional
${If} $SkippedL <> 0
${AndIf} $SkippedC <> 0
GetDlgItem $0 $hwndparent 3
EnableWindow $0 0
${EndIf}
FunctionEnd

以Test /SkipL /SkipC的身份运行以跳过两者。

或者：

OutFile Test.exe
RequestExecutionLevel user
InstallDir $Temp
!include LogicLib.nsh
!include FileFunc.nsh
Page License "" LicShow
Page Components
Page Directory
Page InstFiles
Function LicShow
Var /Global HasSkipped
${GetParameters} $0
ClearErrors
${GetOptions} $0 "/Skip=" $0
${IfNot} ${Errors}
${AndIf} $0 < 4 ; Don't let user skip InstFiles
${AndIf} $HasSkipped = 0
StrCpy $HasSkipped 1
SendMessage $HWNDPARENT 0x408 $0 ""
${EndIf}
FunctionEnd

并作为CCD_ 9运行。
