在卸载模式下使用嵌套在宏中的 StrLoc

如何解决在卸载模式下使用嵌套在宏中的 StrLoc

我不是 NSIS 的专家用户...在编译脚本时我收到以下错误：

<div class="characterChoices hoverEffect" id="rogue">
  <button class="flex optionBackground classChoice" id="rogueButton" type="button">
  <div class="classselection">
    <div class="sectioninfowrapper">
      <h3>ROGUE</h3>
       <img src="img/infoicon1.png" class="infoiconwrapper2" id="roguePopup">
       <span class="hidden popupStyling" id="rogueInfoPopup">Rogues are real sneaky.</span>
     </div>
     <img src="img/banner.png" width="100%">
   <div class="sectioninfowrapper">
     <p>Primary Ability</p>
     <img src="img/infoicon1.png" class="infoiconwrapper1" id="roguePrimaryAbilityPopup">
     <span class="hidden popupStyling" id="roguePrimaryAbilityInfoPopup">You're naturally light on your feet.</span>
    </div>
    <p class="classinfo">Dexterity</p>
 </div>
   <img src="img/rogue.png" alt="rogue">
</button>
</div>

卸载时调用以下函数：

!insertmacro: FUNCTION_STRING_StrLoc_Call
Call must be used with function names starting with "un." in the uninstall section.

反过来，下面的代码也被调用：

Function un.Uninstall
; some code

${un.GetMsOfficeVersion} $R0

; some code
FunctionEnd

我知道问题是由于调用了 !macro GetMsOfficeVersion ; some code StrCpy $R0 0 loop: ClearErrors EnumRegValue $R1 HKCU "Microsoft\Office\16.0\Common\Licensing\LastKnownC2RProductReleaseId" $R0 IfErrors done IntOp $R0 $R0 + 1 ReadRegStr $R2 HKCU "Microsoft\Office\16.0\Common\Licensing\LastKnownC2RProductReleaseId" $R1 ${StrLoc} $R1 "$R2" "365" ">" StrCmp $R1 "" +3 0 ;+3 if substring is not found StrCpy $R1 "16.0" Goto found ${StrLoc} $R1 "$R2" "2019" ">" StrCmp $R1 "" loop 0 ;loop if substring is not found StrCpy $R1 "16.0" Goto found done: ; other code !macroend !macro _GetMsOfficeVersion Result ${CallArtificialFunction} GetMsOfficeVersion Pop "${Result}" !macroend ; Insert function as an installer and uninstaller function. !define GetMsOfficeVersion "!insertmacro _GetMsOfficeVersion" !define un.GetMsOfficeVersion "!insertmacro _GetMsOfficeVersion" 函数。安装模式和卸载模式应该是不同的，也就是${StrLoc}和${StrLoc}，但是不知道怎么用这个代码结构

任何帮助将不胜感激...提前致谢

解决方法

您可以检查 __UNINSTALL__ 定义以判断您是否在卸载程序代码中：

!include StrFunc.nsh
${StrLoc}
${UnStrLoc}


!macro testmacro
!ifdef __UNINSTALL__
!define /ReDef MyUn "un"
!else
!define /ReDef MyUn ""
!endif

StrCpy $R2 "3654321"
${${MyUn}StrLoc} $R1 "$R2" "365" ">"
DetailPrint $R1
!macroend

Section
!insertmacro testmacro
Goto +2
WriteUninstaller $Temp\Un.exe
SectionEnd

Section Uninstall
!insertmacro testmacro
SectionEnd

这个不太理想，我看看下个版本能不能让StrFunc使用CallArtificialFunction。
