I’ve been using the non-DB version of Logseq with the Org-mode syntax (not markdown) for years now, and whilst there are parts of the Org syntax that are clearly outdated in a markdown-dominated world, there are (as I understand) many things it can do that markdown simply cannot.
One of these appears to be sub/superscript — something I make heavy use of.
Djot seems relatively close to a markdown superset and adds back all of the features that I think would be lost by moving to markdown-only in the DB version (in addition to several other goodies). There are some places where it’s not 100% compatible with markdown, but I think the added functionality would be more than worth it. Those incompatibilities are intentional choices that make parsing Djot trivial and linear-time; it could only improve Logseq’s performance.
I’m more than happy to write a Clojure Djot parser for Logseq (I love Clojure and writing parsers), but obviously it’s important to know if people are interested in this sort of thing first!
Check out https://djot.net/ and let me know what you think.
In my opinion, Markdown is often unacceptably inexpressive for note-taking, so I’d love to see Logseq’s new version support something better!
