将时间戳添加到编译的sass / scss [英] Add timestamps to compiled sass/scss

问题描述

是否可以使用SASS在已编译的CSS文件上自动添加时间戳记？
eg

Is it possible to automatically add a timestamp on the compiled CSS file using SASS? e.g.

/* CSS Compiled on: {date+time} */
...compiled css goes here...

我检查了SASS和Compass文档，但没有提到这样的功能。

I've checked the SASS and Compass docs but no mention of such a feature.

推荐答案

我不知道有任何内置的SASS或指南针功能，但它不是太难添加一个自定义的Ruby函数来做。 （请参阅SASS中的添加自定义函数一节请参阅此处。）

I don't know of any built-in SASS or Compass feature for this, but it's not too hard to add a custom Ruby function to do it. (See the section entitled "Adding Custom Functions" in the SASS reference here.)

使用Ruby函数的文件看起来像这样（我们称之为timestamp.rb）：

Your file with the Ruby function would look like this (let's call it "timestamp.rb"):

module Sass::Script::Functions
    def timestamp()
        return Sass::Script::String.new(Time.now.to_s)
    end
end

您可以在SASS文件中引用新的时间戳功能，如下所示：

And you'd reference the new timestamp function in your SASS file like this:

/*!
 * CSS Compiled on: #{timestamp()}
 */

您只需要确保在编译SASS时加载timestamp.rb文件，无论是通过Compass配置文件，还是使用 - require 参数与SASS命令行。当所有的描述和完成，你应该得到如下输出：

You just need to make sure your "timestamp.rb" file is loaded when you compile the SASS, either by requiring it from a Compass config file, or by using the --require parameter with the SASS command line. When all is said and done, you should get output like the following:

/*
 * CSS Compiled on: 2012-10-23 08:53:03 -0400
 */
