Re: [Python-markdown-discuss] List-like blockprocessor

[Waylan L. <way...@ic...>]

Kalle,

I would simply subclass the `UListProcessor` class and override the 
regex (`UListProcessor.RE`) so that it also matched your new bullet 
type, and then use the new subclass as a replacement for the 
`UListProcessor` instance. After all, all you are doing is adding a new 
bullet type for unordered lists.

That said, I would strongly suggest you not use the hash character 
(`#`) as a bullet. It already serves as a hash style header. How would 
you differentiate between a header nested in a list item and your new 
list type? For example, consider your example list:

    * List begins here

        # New list-like thing

In standard Markdown, that would render correctly as:

    <ul>
        <li>
            <p>List begins here</p>
            <h1>New list-like thing</h1>
        </li>
     </ul>

In my experience, it is best **not** to introduce new syntax which 
directly conflicts with existing syntax. Of course, if you are also 
removing support for hash style headers, then that may make sense.
