Markdown，在块级 html 中启用 Markdown 处理

发布于 2024-11-02 10:08:16 字数 463 浏览 0 评论 0原文

请注意，Markdown 格式化语法不会在块级 HTML 标记内进行处理。例如，您不能在 HTML 块内使用 Markdown 样式的强调。

我想将一些降价包装在 div 标签中，并仍然让它来处理该降价。有没有办法用开关或其他东西来做到这一点？

例如，

<div>

* * *

The asterisks would still become an <hr/>

</div>

我使用 RDiscount 作为降价过滤器。非常感谢任何帮助。

From Daring Fireball's Markdown doc

Note that Markdown formatting syntax is not processed within block-level HTML tags. E.g., you can’t use Markdown-style emphasis inside an HTML block.

I want to wrap some markdown in div tags and still get it to process that markdown. Is there a way to do this with a switch or something?

e.g

<div>

* * *

The asterisks would still become an <hr/>

</div>

I'm using RDiscount as the markdown filter. Any help is much appreciated.

Maruku 支持 HTML 块内的 Markdown。

我给 Halst 的答案打了分，因为它是正确的，但我在以这种方式使用 Maruku 时遇到了几个问题，例如它剥离了 unicode 并重新格式化了现有的 html，而我不希望它触及这些内容并导致问题。所以，我必须自己解决这个问题，这就是我想到的：

# encoding: UTF-8
module MarkdownFilters

  # This finds html tags with "markdown='1'" as an attribute, runs markdown over the contents, then removes the markdown attribute
  class InsideBlock
    require 'hpricot'


    def self.run( content, markdown_parser=nil )    
      if markdown_parser.nil?
        require 'rdiscount' 
        markdown_parser=RDiscount
      end
      doc = Hpricot(content) 

      (doc/"*[@markdown='1']").each do |ele|  
        ele.inner_html = markdown_parser.new(ele.inner_html).to_html
        ele.remove_attribute("markdown")
      end

      doc.to_s
    end # run

  end # class
end # module

我从 Maruku 那里偷来了用“markdown='1'”属性标记 html 的想法，这样它就可以与它互换。

I gave Halst the points for the answer as it's correct, but I encountered several problems with using Maruku in this way, such as it stripping out unicode and reformatting existent html that I didn't want it to touch and caused problems. So, I had to sort it out myself and this is what I came up with:

# encoding: UTF-8
module MarkdownFilters

  # This finds html tags with "markdown='1'" as an attribute, runs markdown over the contents, then removes the markdown attribute
  class InsideBlock
    require 'hpricot'


    def self.run( content, markdown_parser=nil )    
      if markdown_parser.nil?
        require 'rdiscount' 
        markdown_parser=RDiscount
      end
      doc = Hpricot(content) 

      (doc/"*[@markdown='1']").each do |ele|  
        ele.inner_html = markdown_parser.new(ele.inner_html).to_html
        ele.remove_attribute("markdown")
      end

      doc.to_s
    end # run

  end # class
end # module

I stole the idea of marking the html with a "markdown='1'" attribute from Maruku, so it can be interchanged with it.
