WiX中的方括号[]语法是什么意思 [英] What does square brackets [ ] syntax mean in WiX

问题描述

我正在使用 WiX 工具集和 本手册.我遇到了以下语法

I'm creating an installer for IIS website using WiX toolset and using this manual. I've came across following syntax

<iis:WebSite Id="DemoWebsiteWebsite" Description='Demo Website' Directory='INSTALLFOLDER' AutoStart='yes' StartOnInstall='yes'>
  <iis:WebAddress Id="AllUnassigned" Port="80" />
  <iis:WebApplication Id="DemoWebsiteApplication" Name="[DemoWebsiteWebsite][WEBSITE_ID]" WebAppPool="DemoWebsiteAppPool"></iis:WebApplication>
</iis:WebSite>

我对 [] 语法和此处使用网站 ID 的方式感到困惑.我需要为此使用用户输入的一些自定义值.所以我有以下问题:

I'm confused by the [] syntax and the way website id is used here. I need to use some custom values entered by user for that. So I have following questions:

1. [] 语法在 WiX 中是什么意思?它与用于访问定义值的 $() 语法有何关系?
2. 像这里 [DemoWebsiteWebsite][WEBSITE_ID] 这样的两个 [] 相互跟随有什么额外的含义吗?
3. 为什么在 [DemoWebsiteWebsite] 表达式中使用网站 ID?这只是巧合还是命名约定?
4. [] 中允许使用哪些值?有他们的清单吗?
5. 我在哪里可以找到有关此语法及其使用情况的更多信息?

1. What does the [] syntax mean in WiX? How it is related with the $() syntax that used to access the defined value?
2. Is there any additional meaning for two [] following each other like here [DemoWebsiteWebsite][WEBSITE_ID]?
3. Why the WebSite Id is used in [DemoWebsiteWebsite] expression? Is that just a coincidence or naming convention?
4. What are the allowed values to be used inside []? Is there any kind of list for them?
5. Where can I find additional info about this syntax and cases it is used for?

推荐答案

这是将 Windows Installer 属性解析为实际值的方式.如果您在 MSI 对话框中输入了一个名为 WEBSITE 的属性，您可以通过将其放在方括号中来将其解析为实际值.这就是为什么您会看到 [TARGETDIR]、[SourceDir] 等内容.大多数生成 MSI 文件的工具都使用该语法，因为它是 Windows Installer 的东西.

This is the way that Windows Installer properties are resolved to the actual values. If you entered a property called WEBSITE into an MSI dialog you'd get that resolved to the actual value by putting it in square brackets. That's why you see things like [TARGETDIR], [SourceDir] and so on. The syntax is used in most tools that generate MSI files because it's a Windows Installer thing.

格式化的 Windows 安装程序

所以 1 - 它们是 MSI 文件中的属性，标准的 Windows Installer 属性或用户创建的属性:

So 1 - they are properties in the MSI file, either standard Windows Installer properties or user-created ones:

属性参考

和 2，它们只是连接在一起的两个属性.它们区分大小写，所以不要对大小写马虎.其他点在了解它们是安装程序属性后应该清楚.

and 2, they are just two properties concatenated. They are case-sensitive so don't be sloppy with the case. The other points should be clear after understanding that they are installer properties.

WiX 源代码中的 $() 值是编译时的 - 它们在构建时解析为实际值.[] 值在安装时解析.

The $() values in WiX source are compile time - they resolve at build time to actual values. The [] values resolve at install time.
