LangString DESC_sec1 ${LANG_ENGLISH} "sec1 files"
Section /o "sec1" sec1

SectionEnd

LangString DESC_sec2 ${LANG_ENGLISH} "sec2 files"
Section /o "sec2" sec2

SectionEnd

LangString DESC_sec3 ${LANG_ENGLISH} "sec3 files"
Section /o "sec3" sec3

SectionEnd


Var test
Function .OnInit
  StrCpy $test "sec2"
  !insertmacro SelectSection $test

FunctionEnd

如何 select 在运行时按节名称节？在示例中总是 select 编辑第一部分（认为这是一个错误）

但是如果我这样重写

!insertmacro SelectSection ${sec2}

一切正常...

有没有办法从变量中按名称 select 部分？

一些长文一些长文一些长文一些长文一些长文本一些长文本一些长文本一些长文本

Answer 1

节通过其 ID 访问，该 ID 是在编译时设置的数字：

Section "Foo"
SectionEnd
Section "Bar" SID_BAR
SectionEnd
Section "Baz"
SectionEnd

Page Components
Page InstFiles

!include Sections.nsh

Function .onInit
  !insertmacro UnselectSection ${SID_BAR}
FunctionEnd

如果您想使用显示名称，则必须手动枚举这些部分：

Section "Foo"
SectionEnd
Section "Bar"
SectionEnd
Section "Baz"
SectionEnd

Page Components
Page InstFiles

!macro GetSectionIdFromName name outvar
Push "${name}"
Call GetSectionIdFromName 
Pop ${outvar} ; ID of section, "" if not found
!macroend
Function GetSectionIdFromName 
Exch  ; Name
Push 
Push 
StrCpy  -1
ClearErrors
loop:
    IntOp   + 1
    SectionGetText  
    IfErrors fail
    StrCmp   "" loop
    StrCpy  
    Goto done
fail:
StrCpy  ""
done:
Pop 
Pop 
Exch 
FunctionEnd


!include Sections.nsh
!include LogicLib.nsh

Function .onInit
  StrCpy  "Bar" ; The name we are looking for
  !insertmacro GetSectionIdFromName  [=11=]
  ${If} [=11=] != ""
      !insertmacro UnselectSection [=11=]
  ${EndIf}
FunctionEnd
