sass的"font-url"在哪里?方法得到定义? [英] Where does the sass "font-url" method get defined?

问题描述

bourbon 使用font-url Rails具有方法font_url，我相当确定这是正在调用的方法.但是，我找不到这两件事之间的联系.我已经探究了bourbon，sass，sass-rais和rails的代码库.

Rails has the method font_url which I'm fairly certain is what is being invoked. However, I can't find where the connection between these two things is made. I have explored the codebases of bourbon, sass, sass-rais, and rails.

font-url在哪里定义，和/或在它与rails font_url之间建立连接?

Where is font-url defined, and/or the connection between it and rails's font_url made?

更新

澄清:我的最终目标是在rubyland中定义自己的助手，它们是font_url的同级兄弟.

Clarification: my ultimate goal is to define my own helpers in rubyland which are siblings to font_url.

推荐答案

font-url是rails资产管道的一部分，就像image-url 一样.如果您查看 rail guides ，则会清楚地说明

font-url is a part of rails asset pipeline just like image-url. If you look at rail guides it clearly says

使用资产管道时，必须重新编写资产路径，并且sass-rails为以下资产类别提供-url和-path帮助器(在Sass中带连字符，在Ruby中加强调):图像，字体，视频，音频，JavaScript和样式表.

When using the asset pipeline, paths to assets must be re-written and sass-rails provides -url and -path helpers (hyphenated in Sass, underscored in Ruby) for the following asset classes: image, font, video, audio, JavaScript and stylesheet.

因此，如果您使用的是 font-url("some_font")，它将在app/assets/font目录中查找some_font

So if you are using font-url("some_font") it will look for some_font in app/assets/font directory

更新:

正如文档中提到的那样，如果您使用的是sass ，那么您可以将资产与混合的url(image-url)一起使用，但是如果您使用的是ruby文件，则

As it is mentioned in docs that if you are using sass then your can use your assets with hypenated urls(image-url) but if you are using a ruby file then those helpers would be underscored (image_url) probably because Ruby doesn't like you having methods or variables with hyphens in the name syntactically, but semantically, there's nothing wrong with it
