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

如何在运行时通过节名称选择节？在示例中，始终选择第一部分（认为是一个错误）

但是如果我这样重写

!insertmacro SelectSection ${sec2}

一切正常...

是否可以从变量中按名称选择部分？

一些长文本一些长文本一些长文本一些长文本一些长文本一些长文本一些长文本一些长文本

Answer 1

部分通过其ID（在编译时设置的数字）进行访问：

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

如果要使用显示名称，则必须手动枚举以下部分：

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 $1 ; Name
Push $2
Push $3
StrCpy $2 -1
ClearErrors
loop:
    IntOp $2 $2 + 1
    SectionGetText $2 $3
    IfErrors fail
    StrCmp $3 $1 "" loop
    StrCpy $1 $2
    Goto done
fail:
StrCpy $1 ""
done:
Pop $3
Pop $2
Exch $1
FunctionEnd


!include Sections.nsh
!include LogicLib.nsh

Function .onInit
  StrCpy $1 "Bar" ; The name we are looking for
  !insertmacro GetSectionIdFromName $1 $0
  ${If} $0 != ""
      !insertmacro UnselectSection $0
  ${EndIf}
FunctionEnd

按变量选择部分
