Chapter 9. Config Files

第九章.配置文件

Config files are handy for designers to manage global template variables from one file. One example is template colors. Normally if you wanted to change the color scheme of an application, you would have to go through each and every template file and change the colors. With a config file, the colors can be kept in one place, and only one file needs to be updated.

配置文件有利于设计者管理文件中的模板全局变量。最简单的例子就是模板色彩变量。一般情况下你如果想改变一个程序的外观色彩,你就必须通过去更改每一个文件的颜色变量。如果有这个配置文件的话,色彩变量就可以保存在一个地方,只要改变这个配置文件就可以实现你色彩的更新。

Example 9-1. Example of config file syntax

例 9-1 配置文件语法例子

# global variables
pageTitle = "Main Menu"
bodyBgColor = #000000
tableBgColor = #000000
rowBgColor = #00ff00

[Customer]
pageTitle = "Customer Info"

[Login]
pageTitle = "Login"
focus = "username"
Intro = """This is a value that spans more
 than one line. you must enclose
			it in triple quotes."""

# hidden section
[.Database]
host=my.domain.com
db=ADDRESSBOOK
user=php-user
pass=foobar

Values of config file variables can be in quotes, but not necessary. You can use either single or double quotes. If you have a value that spans more than one line, enclose the entire value with triple quotes ("""). You can put comments into config files by any syntax that is not a valid config file syntax. We recommend using a # (hash) at the beginning of the line.

配置文件变量值能够在引号中使用,但是没有必要。你可以用单引号或者双引号。如果你有一个不只在一个区域内使用的变量值,你可以使用三引号(""")将它完整的封状起来,可以把它们放金配置文件,只要没有语法错误。我们建议在程序行前使用 “#”加一些注释信息来标示。

This config file example has two sections. Section names are enclosed in brackets []. Section names can be arbitrary strings not containing [ or ] symbols. The four variables at the top are global variables, or variables not within a section. These variables are always loaded from the config file. If a particular section is loaded, then the global variables and the variables from that section are also loaded. If a variable exists both as a global and in a section, the section variable is used. If you name two variables the same within a section, the last one will be used.

上面关于配置文件的例子共有两个部分。每部分的名称都是用一个“[]”给括起来。每部分的名称命名规则就是任意的字符串,只要不包括有符号“[”或者“]”。例子开头的四个变量都是全局变量,也就是说不仅仅是可以在一个区域内使用。这些变量总是从配置文件中载入。如果某个特定的局部变量已经载入,这样全局变量和局部变量都还可以载入。如果当某个变量名既是全局变量又是局部变量时,局部变量将被优先赋予值来使用。如果在一个局部中两个变量名相同的话,最后一个将被赋值使用。

Config files are loaded into templates with the built-in function {config_load} .

配置文件是通过内建函数载入到模板 { config load }

You can hide variables or entire sections by prepending the variable name or section name with a period. This is useful if your application reads the config files and gets sensitive data from them that the template engine does not need. If you have third parties doing template editing, you can be certain that they cannot read sensitive data from the config file by loading it into the template.

你可以在某个段时期通过预先想好的变量名或者局部名隐藏变量或者完整的一个节。当你的应用程序读取配置文件和取得有用数据而不用读取模板时这个非常有用,如果你有第三方来做模板编辑的话,可以肯定的说它们不能通过载入配置文件到模板而读取到任何有用的数据。
