解析Markdown时保留HTML实体 [英] Retain HTML Entities When Parsing Markdown

问题描述

我已经用尽了我的研究，尝试了许多无效的方法，希望我能忽略某种简单的解决方案:

I have exhausted my research and tried many methods to no effect and am hoping I'm overlooking some kind of simple solution:

我正在使用Jekyll网站生成用于电子邮件的HTML文件，并且需要对特殊字符(例如破折号和智能引号)使用HTML实体，以避免符号解释不正确(内容类型/字符集)由于复杂性，有时会从电子邮件头中剥离出来.)

I am using a Jekyll site to produce HTML files for e-mail and need to use HTML entities for special characters (such as em-dashes and smart quotes) in order to avoid improper symbol interpretation (the content-type/charset is at times stripped out of the e-mail head due to complexities I won't get into here.)

我的问题是当解析为HTML输出时，解析我的Markdown似乎会将所有书面的HTML实体转换为特殊字符，而我无法使用通用方法进行转义.当我在markdown中键入’以产生正确的卷曲引号时，它会转换为HTML中的’符号(而不是在HTML中保留’).如果我尝试使用反引号将其转义，它将不会在HTML中转换&rsquo，但是会将其放置在标记内，这会导致它呈现为’而不是’.有没有一种方法可以保留键入的HTML实体以保留特殊字符，或者甚至可以更好地在解析时将特殊字符转换为HTML实体(在HTML中)?

My problem is that parsing my Markdown appears to convert all of my written HTML entities into the special characters when output as HTML, and I am unable to escape with common methods. When I type ’ into markdown to produce a right curly quote it is converted to the ’ symbol within my HTML (instead of retaining ’ in my HTML). If I try to escape it with back-ticks it will not convert &rsquo in the HTML but it places it within <code> tags which cause it to render as ’ and not ’. Is there a way to retain typed-out HTML entities for special characters or -- even better -- convert special characters into to HTML entities (in the HTML) when parsed?

我正在与Jekyll一起使用Kramdown markdown解析器.我什至在将Kramdown中的entity_output选项指定为: as_input时都没有成功.任何帮助深表感谢！

I am using the Kramdown markdown parser with Jekyll. I have even gone as far as specifying the entity_output option in Kramdown to : as_input without success. Any help is much appreciated!

推荐答案

文档状态如下:

    --entity-output ARG
     Defines how entities are output

     The possible values are :as_input (entities are output in the same
     form as found in the input), :numeric (entities are output in numeric
     form), :symbolic (entities are output in symbolic form if possible) or
     :as_char (entities are output as characters if possible, only available
     on Ruby 1.9).

     Default: :as_char
     Used by: HTML converter, kramdown converter

因此，让我们尝试以下选项:

So lets try those options:

$ kramdown --version
1.11.1 
$ kramdown
‘foo’
<p>‘foo’</p>
$ kramdown --entity-output=as_input
&lsquo;foo&rsquo;
<p>&lsquo;foo&rsquo;</p>
$ kramdown --entity-output=symbolic
&lsquo;foo&rsquo;
<p>&lsquo;foo&rsquo;</p>
$ kramdown --entity-output=numeric
&lsquo;foo&rsquo;
<p>&#8216;foo&#8217;</p>
$ kramdown --entity-output=as_char
&lsquo;foo&rsquo;
<p>‘foo’</p>
$ ruby --version
ruby 1.9.3p484 (2013-11-22 revision 43786) [x86_64-linux]

请注意，我拥有Kramdown 1.11版和Ruby 1.9版.如果您使用的是较早版本，则可能无法正常工作.

Notice that I have Kramdown version 1.11 and Ruby version 1.9. if you have earlier versions, then things may not work properly.
