Markdown中的RTL [英] RTL in Markdown

问题描述

是否存在现有的Markdown附加规范，其中包括对RTL语言的支持?

Is there any existing addon spec for markdown that includes support for RTL languages?

我希望的是

This paragraph is left to right
<- This paragraph is right to left

或者什么...我可以调整解析器来处理此问题，但是我想确保它不存在.

Or something... I can tweak my parser to handle this but I want to make sure it doesn't exist already.

推荐答案

这是Markdown的JavaScript实现，(根据提交的评论)增加了对RTL语言(即阿拉伯语，希伯来语，叙利亚语，塔纳语)的支持.添加更多语言似乎很容易.

Here is a JavaScript implementation of Markdown, which (according to the commit comments) adds support for RTL languages, namely Arabic, Hebrew, Syriac, Thaana. And it seems trivially easy to add more languages.

https://github.com/hasenj/showdown/

它基于Showdown， http://attacklab.net/showdown .

It's based on Showdown, http://attacklab.net/showdown.

似乎可以自动理解是否从右向左呈现文本.
考虑以下代码片段:(从GitHub的第一次提交开始)

It seems to automatically understand whether or not to render the text from right to left.
Consider this code snippet: (from the very first commit at GitHub)

var p_tag = "<p>";
var rtl_p_tag = "<p style='direction:rtl; text-align: right'>";

// Check for RTL paragraphs: paragraphs that start with a character
// from an RTL script.
// RTL scripts are: Arabic, Hebrew, Syriac, Thaana
// Unicode ranges reference: http://www.ssec.wisc.edu/~tomw/java/unicode.html
var first_char = str.charCodeAt(str.search(/\S/)); //first non-white-space char
if(first_char >= 1424 && first_char <= 1983) 
{
    p_tag = rtl_p_tag;
}

    str = _RunSpanGamut(str);
    str = str.replace(/^([ \t]*)/g, p_tag);
