如何使用NSIS实现多目录安装设置

nsis 永恒心锁 1165浏览 0评论

有些时候,我们需要让用户设置多个安装目录,如果大家用过 Delphi 就知道了,安装 Delphi 的时候我们可以选择为不同功能的程序(例如共享文件目录,主程序目录,数据库设置程序目录等等)设置不同的安装目录,而这样的功能怎么实现呢,以下为一个很好的例子脚本

!include "MUI.nsh"

Name "Test App"
OutFile "test.exe"

!insertmacro MUI_PAGE_COMPONENTS
Page custom SetCustom LeaveCustom
!insertmacro MUI_PAGE_INSTFILES

!insertmacro MUI_LANGUAGE "SimpChinese"

;--------------------------------

Section "SectionA" SecA
 ReadINIStr $0 "$PLUGINSDIR\test.ini" "Field 4" State
 MessageBox MB_OK "SectionA 的安装路径为:$0"
SectionEnd

Section "SectionB" SecB
 ReadINIStr $0 "$PLUGINSDIR\test.ini" "Field 5" State
 MessageBox MB_OK "SectionB 的安装路径为:$0"
SectionEnd

Section "SectionC" SecC
 ReadINIStr $0 "$PLUGINSDIR\test.ini" "Field 6" State
 MessageBox MB_OK "SectionC 的安装路径为:$0"
SectionEnd


Function .Oninit
 InitPluginsDir
 File /oname=$PLUGINSDIR\test.ini ".\test.ini"
FunctionEnd

Function SetCustom
; 判断勾选的组件,并把未勾选组件的安装路径控件设为不可用
 SectionGetFlags ${SecA} $0
 StrCmp $0 0 0 +2
 WriteINIStr "$PLUGINSDIR\test.ini" "Field 4" "Flags" "Disabled"
 StrCmp $0 1 0 +2 ; 如果组件勾选了,还需要去掉 Disabled,这两行代码不能省略
 WriteINIStr "$PLUGINSDIR\test.ini" "Field 4" "Flags" ""

 SectionGetFlags ${SecB} $0
 StrCmp $0 0 0 +2
 WriteINIStr "$PLUGINSDIR\test.ini" "Field 5" "Flags" "Disabled"
 StrCmp $0 1 0 +2
 WriteINIStr "$PLUGINSDIR\test.ini" "Field 5" "Flags" ""

 SectionGetFlags ${SecC} $0
 StrCmp $0 0 0 +2
 WriteINIStr "$PLUGINSDIR\test.ini" "Field 6" "Flags" "Disabled"
 StrCmp $0 1 0 +2
 WriteINIStr "$PLUGINSDIR\test.ini" "Field 6" "Flags" ""

; 预定义组件安装路径
 WriteINIStr "$PLUGINSDIR\test.ini" "Field 4" "State" "$ProgramFiles"
 WriteINIStr "$PLUGINSDIR\test.ini" "Field 5" "State" "$DeskTop"
 WriteINIStr "$PLUGINSDIR\test.ini" "Field 6" "State" "$WinDir"

 InstallOptions::initDialog /NOUNLOAD "$PLUGINSDIR\test.ini"
 !insertmacro MUI_HEADER_TEXT "选择各组件的安装路径" "必须输入有效路径"
 InstallOptions::show
 Pop $R0

FunctionEnd

Function LeaveCustom
; 判断用户输入的路径是否合法。

 ReadINIStr $0 "$PLUGINSDIR\test.ini" "Field 4" "State"
 StrCmp $0 "" +2
 IfFileExists "$0\*" +3
 MessageBox MB_OK|MB_ICONSTOP "组件 A 的安装路径无效!"
 Abort

 ReadINIStr $0 "$PLUGINSDIR\test.ini" "Field 5" "State"
 StrCmp $0 "" +2
 IfFileExists "$0\*" +3
 MessageBox MB_OK|MB_ICONSTOP "组件 B 的安装路径无效!"
 Abort

 ReadINIStr $0 "$PLUGINSDIR\test.ini" "Field 6" "State"
 StrCmp $0 "" +2
 IfFileExists "$0\*" +3
 MessageBox MB_OK|MB_ICONSTOP "组件 C 的安装路径无效!"
 Abort
FunctionEnd
