nsis 高级卸载日志 - 卸载程序需要驻留在不同的目录中

Question

要求 1： 要求我们的卸载程序仅删除安装程序安装的特定文件夹中的文件（即安装后添加的任何文件必须保持原样）。

要求 2： 还要求卸载程序驻留在上述文件夹以外的特定位置。

我在此处找到并尝试了“高级卸载日志 NSIS 标头”： http://nsis.sourceforge.net/Advanced_Uninstall_Log_NSIS_Header

虽然高级卸载日志 NSIS 标头看起来很有希望，（很好地满足要求 1），但我无法确定是否可以使其也适用于要求 2。

是否可以使用标头仅卸载已安装的文件并从与创建 .dat 文件的目录不同的目录调用？

提前致谢。

Answer 1

在 AdvUninstLog.nsh 中，您应该注释掉与 UNINST_EXE 相关的任何内容，尤其是 WriteUninstaller 行。我不确定您是否希望 .dat 和卸载程序位于同一目录中，所以为了安全起见，我使用了单独的目录。

...
!include AdvUninstLog.nsh
!insertmacro UNATTENDED_UNINSTALL
Page Directory 
Page InstFiles

Function .onInit

    !insertmacro UNINSTALL.LOG_PREPARE_INSTALL

FunctionEnd


Function .onInstSuccess

    !insertmacro UNINSTALL.LOG_UPDATE_INSTALL

FunctionEnd

Section "Main Application"

    SetOutPath "$InstDir\foo"
    WriteUninstaller "$InstDir\foo\uninst.exe"

    SetOutPath "$InstDir\data"
    !insertmacro UNINSTALL.LOG_OPEN_INSTALL
    File /r "${NSISDIR}\Plugins\*" ; "random" files
    !insertmacro UNINSTALL.LOG_CLOSE_INSTALL

    WriteRegStr ${INSTDIR_REG_ROOT} "${INSTDIR_REG_KEY}" "InstallDir" "$InstDir"
    WriteRegStr ${INSTDIR_REG_ROOT} "${INSTDIR_REG_KEY}" "DisplayName" "${APP_NAME}"
    WriteRegStr ${INSTDIR_REG_ROOT} "${INSTDIR_REG_KEY}" "UninstallString" '"$InstDir\foo\uninst.exe"'

    ; Because the UNINSTALL.LOG_UPDATE_INSTALL macro is responsible for writing the .dat
    ; it is important to set $InstDir to the directory you want it to be located in.
    ; This must be done as the last step in your last Section so that $InstDir has
    ; the correct path when .onInstSuccess is executed.
    SetOutPath "$InstDir\bar" ; Make sure the directory exists
    StrCpy $InstDir "$InstDir\bar"

SectionEnd

Section UnInstall

    ; In the uninstaller the initial value of $InstDir is the folder the uninstaller .exe is in.
    ; In this example I put it in a subfolder so we need to get the root of our install:
    GetFullPathname $InstDir "$InstDir\..\"

    ; This is important, it changes $InstDir to the folder where the .dat is located.
    Push $InstDir ; Save
    StrCpy $InstDir "$InstDir\bar" 
    !insertmacro UNINSTALL.LOG_BEGIN_UNINSTALL
    Pop $InstDir ; Restore

    !insertmacro UNINSTALL.LOG_UNINSTALL "$INSTDIR\data"
    !insertmacro UNINSTALL.LOG_END_UNINSTALL
    DeleteRegKey /ifempty ${INSTDIR_REG_ROOT} "${INSTDIR_REG_KEY}"

    ; Because the uninstaller and the .dat were located in their own (unlogged) folders
    ; we need to manually delete them:
    Delete "$INSTDIR\foo\uninst.exe"
    RMDir "$INSTDIR\foo"
    Delete "$INSTDIR\bar\${UNINSTALL_LOG}.dat"
    RMDir "$INSTDIR\bar"

    RMDir "$INSTDIR"
