Haml:控制文本周围的空格 [英] Haml: Control whitespace around text

问题描述

在我的Rails模板中，我想使用HAML完成最终的HTML来实现此效果:

In my Rails template, I'd like to accomplish final HTML to this effect using HAML:

I will first <a href="http://example.com">link somewhere</a>, then render this half of the sentence if a condition is met

最接近的模板:

I will first
= link_to 'link somewhere', 'http://example.com'
- if @condition
  , then render this half of the sentence if a condition is met

但是，您可能会注意到，这会在链接和逗号之间产生一个空格.有什么实际的方法可以避免这种空白?我知道可以删除标记周围的空格的语法，但是可以将这种语法仅应用于文本吗?我真的不喜欢额外标记的解决方案来完成此任务.

You may, however, note that this produces a space between the link and the comma. Is there any practical way to avoid this whitespace? I know there's syntax to remove whitespace around tags, but can this same syntax be applied to just text? I really don't like the solution of extra markup to accomplish this.

推荐答案

通过Haml的助手介绍了一种更好的方法:

A better way to do this has been introduced via Haml's helpers:

= surround '(', ')' do
  %a{:href => "food"} chicken

产生:

(<a href='food'>chicken</a>)

成功:

click
= succeed '.' do
  %a{:href=>"thing"} here

产生:

click
<a href='thing'>here</a>.

开头:

= precede '*' do
  %span.small Not really

产生:

*<span class='small'>Not really</span>

要回答原始问题:

I will first
= succeed ',' do
  = link_to 'link somewhere', 'http://example.com'
- if @condition
  then render this half of the sentence if a condition is met

产生:

I will first
<a href="http://example.com">link somewhere</a>,
then render this half of the sentence if a condition is met
