Fixes #1040 and fixes #1045.
By calling str on all stash elements we ensure they don't raise an error. Worse case, soemthing like `<Element 'div' at 0x000001B2DAE94900>` gets inserted into the output. However, with the override in the md_in_html extension, we actually serialize and reinsert the original HTML. Worse case, an HTML block which should be parsed as Markdown gets skipped by the extension (`<div markdown="block"></div>` gets inserting into the output). The tricky part is testing as there should be no known cases where this ever occurs. Therefore, we forefully pass an etree Element directly to the method in the test. That said, as #1040 is unresolved at this point, I have tested locally with a real existing case and it works well. Related to #1040.
* All non-language classes should always be assigned to the pre tag. * The language identifying class should never be included with the general list of classes. Fixes #1032
A second function, `slugify_unicode` was added rather than changing the existing function so as to maintain backward compatibility. While an `encoding` parameter was added to the `slugify` function, we can't expect existing third party functions to accept a third parameter. Therefore, the two parameter API was preserved with this change.
The HTML parser has been completely replaced. The new HTML parser is built on Python's html.parser.HTMLParser, which alleviates various bugs and simplifies maintenance of the code. The md_in_html extension has been rebuilt on the new HTML Parser, which drastically simplifies it. Note that raw HTML elements with a markdown attribute defined are now converted to ElementTree Elements and are rendered by the serializer. Various bugs have been fixed. Link reference parsing, abbreviation reference parsing and footnote reference parsing has all been moved from preprocessors to blockprocessors, which allows them to be nested within other block level elements. Specifically, this change was necessary to maintain the current behavior in the rebuilt md_in_html extension. A few random edge-case bugs (see the included tests) were resolved in the process. Closes #595, closes #780, closes #830 and closes #1012.
Fixes #918.
Add better logic to admonitions to account for more complex list cases Fixes #1004
Ignore empty braces. Braces must contain at least one non-whitepsace character to be recognized as an attr list. Attr lists for table cells must be at the end of the cell content and must be seperated from the content by at least one space. This appears to be a breaking change. However, it is consistent with the behavior elsewhere. Fixes #898.
Previously, we'd unescape both `&gt;` and `>` to the same string because we were running the & => & replacement first. By changing the order of this replacement, we now convert: `&gt; >` => `> >` as expected. Fixes #988.
