如何根据语言环境加载文件并使用 NSIS 生成安装程序？

Question

我的要求是，我有每个区域设置（语言）的特定文件（Dll、chms 等）。我需要根据语言环境加载这些文件并生成安装程序。卸载时我也应该从 traget 目录中卸载这些文件。

这里我正在做的是在 .onInit 函数中，使用 GetUserDefaultUILanguage() 我正在获取语言环境并检查该语言环境并加载该语言环境下的文件。

这是正确的方法吗？请为此代码提供任何建议。

我们还需要在“语言”部分之前使用“页面”部分吗？

因为我在编译时收到警告，要求在 ;Languages 部分之前使用 ;Pages 部分。

下面是我写的代码片段：

; LocaleDlls.nsi
;
;
; It will install LocaleDlls.nsi into a directory that the user selects.

;--------------------------------
!include LogicLib.nsh
 !include "MUI2.nsh"
; The name of the installer in the path C:\Program Files\LocaleDlls
Name "LocaleDlls"

; The file to write  in the path E:\Source\NULLSOFT\src
OutFile "LocaleDlls.exe"

; The default installation directory in the path C:\Program Files\LocaleDlls
InstallDir $PROGRAMFILES\LocaleDlls

; Registry key to check for directory (so if you install again, it will
; overwrite the old one automatically) It shows the path the path C:\Program Files\LocaleDlls
InstallDirRegKey HKLM "Software\NSIS_LocaleDlls" "Install_Dir"

; Request application privileges for Windows Vista
RequestExecutionLevel admin

; Do we need to use PAGE macros before giving LANGUAGE as when compiling we are getting an error.

;Languages

  !insertmacro MUI_LANGUAGE "English" ; The first language is the default language
  !insertmacro MUI_LANGUAGE "PortugueseBR"

您不需要调用 GetUserDefaultUILanguage，NSIS 调用 GetUserDefaultUILanguage 尝试设置默认值 $language。如果找不到匹配的语言，则使用 .NSI 中指定的第一种语言。所有这些都发生在调用 .onInit 之前，您无需执行任何操作。但是，如果您对 NSIS 选择的语言不满意，可以在 .onInit 中更改 $language。您还可以使用 !insertmacro MUI_LANGDLL_DISPLAY 显示语言选择对话框。

使用MUI时需要在语言之前插入页面，因为语言宏需要知道页面需要哪些字符串。使用 MUI 页面宏 MUI_PAGE_* 而不是本机页面很重要：

!insertmacro MUI_PAGE_WELCOME
Page Custom MyPage ; There is no MUI_PAGE_* macro for this
!insertmacro MUI_PAGE_COMPONENTS
!insertmacro MUI_PAGE_INSTFILES

!insertmacro MUI_LANGUAGE "English" ; Must come after all MUI_PAGE_* macros.
