Where is the tasklist extension?

[zmwangx]

At the moment (0.27.1.gfm.0), the tasklist extension does not show up in --list-extensions; its test case in test/spec.txt is disabled; and it doesn't seem to be mentioned anywhere else in the code base. Am I right it's not included in the code base? Any plan to release it?

The tasklist extension isn't actually implemented in cmark itself; we perform this transformation in our (Ruby) user content stack, in such a way that conforms to the (quite loose) specification. It's not super likely that we'd reimplement it in C at this stage, as the benefit to us would be minimal.

The nature of task lists is that they are quite specific to your implementation — for example, we render our checkboxes disabled, and with specific classes so that JavaScript on the page can attach events to them and re-enable them, for AJAX-y updating of the Markdown contents when they're checked and unchecked. So the likelihood is you'd be best off implementing this yourself anyway, for your particular purpose.

Yeah makes sense, thanks for responding.

(Of course, there can be some differing on this opinion — I have implemented tasklist in my Rust CommonMark library, but it's a really minimal implementation and isn't necessarily useful to many people without further post-processing.)

Cool, I'll check it out.
