您将如何自动检测 Textile 与 Markdown？
我正在考虑同时支持 Textile 和 Markdown 当前项目。 我不想强迫用户选择其中之一。 有没有办法自动检测用户正在使用哪个？ 你会怎么做呢？ 我想找到/开发 JavaScript 和 PHP 解决方案，这样我就可以提供实时预览并在服务器端处理用户输入。
I'm considering supporting both Textile and Markdown on a current project. I would prefer not forcing users to choose one or the other. Is there a way to auto-detect which the user is using? How would you go about this? I'd like to find / develop both a JavaScript and a PHP solution so I can provide live previews as well as process the user input on the server-side.

考虑到用户可能只在发布中使用一种特定的语法元素，因此您必须检查所有内容。 正在寻找“h1”。 显然只有当用户完全使用该元素时才有效。
对于标题之类的东西来说非常简单，但是考虑到 Markdown 将
*this*格式设置为this并且 Textile 会将其转换为< ;strong>这个代替。 因此，您的语法结构不明确，会在每种语言中产生不同的结果。我建议根据用户的选择进行选择。 尝试找出您的用户（或您）通常喜欢哪种语法，为那些想要其他选择的人提供“使用 x 而不是 y”复选框。
Consider that users might only use one specific syntax element in a posting, so you'd have to check for everything. Looking for "h1." obviously only works if the user uses exactly that element.
It's pretty easy with things like headers, but consider that markdown formats
*this*as<em>this</em>and Textile will convert that to<strong>this</strong>instead. So you'd have ambiguous syntax constructs that would yield different results in each language.I'd suggest going with a user choice. Try to find out what syntax is generally preferred by your users (or you), offer an "use x instead of y" checkbox for those who want the other choice.
这真的不应该那么难。 Markdown 不支持以下语法；
...所以您只需扫描它即可检查它是否是纺织品。 非常简单的正则表达式可帮助您在 PHP 代码中开始（扫描以 hX. 或 p. 开头的行）：
您可能能够编写自己的正则表达式来扫描 Markdown。
This really shouldn't be that hard. Markdown does not support the following syntax;
... so you simply scan for that to check if it is textile. Very simple regular expression to get you started (scans for lines beginning with hX. or p.) in PHP code:
You will probably be able to write your own regex to scan for Markdown.
自动检测，我不知道，两者都是基于“自然”打字。
也许您可以要求用户选择一种格式，使用一对单选按钮或其他东西。
Auto-detection, I don't know, both are based on "natural" typing.
Perhaps you can ask the user to choose a format, with a pair of radio-buttons or something.
