方括号[]语法在WiX中意味着什么 [英] What does square brackets [ ] syntax mean in WiX

问题描述

我正在使用WiX工具集为IIS网站创建一个安装程序并使用本手册。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 [] 感到困惑语法和网站ID的使用方式在这里。我需要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. WiX中的 [] 语法是什么意思？它是如何与用于访问定义值的 $（）语法相关联的？


2. 两个是否有任何其他含义 [] 像这里一样跟随 [DemoWebsiteWebsite] [WEBSITE_ID] ？


3. 为什么在 [DemoWebsiteWebsite] 表达式中使用WebSite Id？这只是巧合或命名约定吗？


4. [] 中允许使用的允许值是多少？是否有任何类型的列表？


5. 我在哪里可以找到有关此语法及其用例的其他信息？

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对话框中输入了名为WEBSITE的属性，则可以通过将其放在方括号中将其解析为实际值。这就是你看到[TARGETDIR]，[SourceDir]等等的原因。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Windows Installer

所以1 - 它们是MSI文件中的属性，标准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:

和2，它们只是两个连接的属性。它们区分大小写，所以不要随意使用。在了解它们是安装程序属性之后，其他要点应该清楚。

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源中的$（）值是编译时间 - 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.
