I don't think so, unfortunately -- you'll have to make the initial call to get the topic, and then subsequent calls to grab the raw markdown. I don't think we'll be adding a way to retrieve the raw markdown at the topic level because we wouldn't have any use for it.
Just saw this markdown editor while browsing stack overflow.
Looks like a standalone app as opposed to a web library, unless I misread.
In any case, we don't typically offer compatibility with X markdown editor or whatnot for a variety of reasons:
- Markdown can be disabled in favour of other parsing languages (like BBCode, etc)
- There needs to be support for post-related functions offered by the existing composer, such as topic images, file uploads, tags support, etc.
The short of it is, it takes quite a bit of work to ensure compatibility and full functionality, which is why at current we only support default and redactor.
