如何使用Inno Setup创建可提取.rar存档内容的安装程序? [英] How to create an installer using Inno Setup which extracts the contents of a .rar archive?

问题描述

我想在Inno Setup中创建一个安装程序，以提取预先创建的Data.rar存档的内容.我的意思是应该将rar存档的内容视为应用程序的文件和文件夹.

I want to create an installer in Inno Setup which extracts the content of pre created Data.rar archive. I mean it should treat the contents of the rar archive as files and folders of application.

推荐答案

在Inno Setup中使用外部提取实用程序的通用方法:

A generic way to use an external extraction utility with Inno Setup:

• 创建档案文件
• 将存档嵌入安装程序
• 嵌入了可以将归档文件提取到安装程序的工具
• 使安装程序将存档和工具提取到目标计算机上的临时位置-{tmp}
• 让安装程序运行该工具以提取档案文件

• create the archive
• embed the archive to the installer
• embed a tool that can extract the archive to the installer
• make the installer extract the archive and the tool to a temporary location on target machine - {tmp}
• make the installer run the tool to extract the archive

[Files]
Source: "UnRAR.exe"; DestDir: "{tmp}"; Flags: deleteafterinstall
Source: "Data.rar"; DestDir: "{tmp}"; Flags: deleteafterinstall nocompression 

[Run]
Filename: "{tmp}\UnRAR.exe"; Parameters: "x ""{tmp}\Data.rar"" ""{app}"""

如果要显示减压进度，则必须解析UnRAR输出.有关示例(在Arc上)，请参见如何将.arc解压缩添加到Inno Setup中?

还是使用UnRAR.dll，就像 Inno Setup-如何在取消压缩页面中添加取消按钮一样，使用unarc.dll?

Or use UnRAR.dll, similarly as unarc.dll is used in Inno Setup - How to add cancel button to decompressing page?

请注意，UnRAR.exe工具是免费的，可以用于这些目的. license.txt的摘录:

Note that the UnRAR.exe tool is free and can be used for these purposes. An extract from its license.txt:

1. UnRAR实用程序可以免费分发.允许的 在其他软件包中分发UnRAR.

1. The UnRAR utility may be freely distributed. It is allowed to distribute UnRAR inside of other software packages.
