步骤2a：添加自定义变量
如何在谷歌分析标签的用户自定义变量？
能编辑自定义函数和自定义变量，因此这种模板语言完万能扩展。
You can make custom functions and custom variable modifiers, so the template language is extremely extensible.
当用户成功登录，你知道他们是会员，因此你创建一个持续性自定义变量。
When a user successfully logs in, you know that they're a member, so you create a custom variable which is persistent.
在编写头文件之前，我们需要引入一些额外的预处理器设施。预处理器允许我们自定义变量。
Before we write our own header, we need to introduce some additional preprocessor facilities. The preprocessor lets us define our own variables.
配置自定义执行器有两种方式——工作流变量和/或动作配置。
There are two options of configuring custom executor – workflow variables and/or action configuration.
动态类型变量可以使用自定义绑定程序来决定在运行时如何调用方法，这非常适合本文提到的互操作解决方案。
Variables with the type dynamic can use custom binders to determine how to call a method at runtime, which would fit well with interop scenarios such as this.
内联人工任务另外还可以访问周围的业务流程上下文信息，例如流程变量、流程自定义属性等等。
Inline human tasks additionally have access to the surrounding business process context information like process variables, process custom properties, and so on.
在此类文件内，还有一些需要用户自定义的变量替换。
Inside this class file, we also have variable substitutions we want our users to customize.
这些变量常常用XML表示，XML提供了一个灵活的框架允许文档作者使用自定义的标签和标记描述内容。
The variables are often expressed using XML, which provides a flexible framework for document authors to describe content using custom tags and markup.
JSF具有用于自定义jsfel表达式中的顶级变量的解析的机制。
JSF has a mechanism for customizing the resolution of top-level variables in JSF el expressions.
你可以可以为变量指明数据类型，输入参数，来自函数的返回值，用户自定义函数以及模板。
You are also able to specify data types for variables, input parameters, return values from functions, user-defined functions and templates.
第 2部分中，我们增强了在 第 1 部分 中开发的解决方案，使之包括创建、更新和删除功能，包括用本地附加的变量及基本的转换来自定义生成SDO。
Part 2 enhanced the solution from Part 1 to include create, update, and delete functions, plus customizations to the generated SDOs with local variable addition and basic transformations.
UNIX应用程序也经常使用环境变量进行自定义的工作。
UNIX applications often use environment variables for customization, too.
spring - web包是spring发布的一部分，附带有自定义J SF变量解析器，可构建此桥梁。
The spring-web package, part of the spring distribution, ships with a custom JSF variable resolver to establish this bridge.
程序的man页面中通常包含对自定义应用程序环境变量的说明。
Custom application environment variables are typically documented in the program's man pages.
如果你以后希望自定义一个特别的项目，其它的变量也可以在这块定义。
Other variables can also be defined in this block if you wish to customize a particular project further.
解决方案：您可能需要调整IDS并设置ApplicationServer自定义属性中的某些Informix环境变量。
Resolution: You might need to tune IDS and set some Informix environment variables in Application Server custom properties. The following Informix configuration parameter needs to be set.
编写自定义着色器时，您应该始终指定浮点变量的精度。
You should always specify the precision of floating point variables when writing custom shaders.
已经有一份关于(跟变量类似的)自定义属性的草案了，名称叫作CSS自定义属性暨层叠式变量。
There is already a draft about variable-like custom properties, under the title of CSS custom properties for Cascading Variables.
变量调节器作用于变量、自定义函数或字符串。
Variable modifiers can be applied to variables, custom functions or strings.
嵌套容器允许对控件的各个部分进行设计，不需要为每个子控件提供显式的序列化成员变量或自定义序列化程序。
Nested containers allow sections of a control to be designable, without requiring an explicit serialized member variable or a custom serializer for each sub control.
当变量用来表示用户在命令行上或环境中所自定义的常数时，习惯上会全部以大写来编写其名称。
Variables representing constants a user might want to customize on the command line or in the environment are written in all uppercase, by convention.
通过变量和用户自定义函数的使用，我们可以封装应用程序和算法。
By using variables and user-defined functions we can encapsulate applications and algorithms.
正如其他的预处理器变量一样（第2.9.2 节），不可以使用NULL这个标识符给自定义的变量命名。
As with any preprocessor variable ( Section 2.9.2, p. 71) we should not use the name NULL for our own variables.
唯一的特例是需要声明嵌套类型的变量的情况，在生成子类或其他高级自定义等极少数情况下需要声明嵌套类型的变量。
The only exception to this is when variables of the nested type need to be declared in rare scenarios such as subclassing or other advanced customization scenarios.
OOP语言可以让你自定义对象和变量类型。
An OOP language allows you to define your own objects and make your own variable types.
所以，通过明智而审慎地使用变量和用户自定义函数，以及尽量使用标准工具以避免特殊的功能，我们就可以提高makefile的可移植性。
So, by judicious use of variables and user-defined functions, and by minimizing the use of exotic features and relying on standard tools, we can increase the portability of our makefiles.
当然你也可以将其它的值例如尺寸、样式、等等的总之是可自定义的选项都放到公共变量中。
Of course, you should also put another values such as default dimensions, styles, etc., in another words, all customizable options into public variables.
当然你也可以将其它的值例如尺寸、样式、等等的总之是可自定义的选项都放到公共变量中。
