Creator of Orgro here. > they only support a tiny subset of the format I think Orgro's parser[0] is pretty complete at this point. If you can find an Org syntax that Orgro doesn't support, please let me know. However I should be very clear here: > they can't support any of the features that require the rest of emacs to be present which is a lot of of the value This is absolutely true and unlikely to change anytime soon. As I'm sure you know, parsing the syntax correctly is not at all the same as supporting all of the features built on top of the AST. [0]: https://github.com/amake/org_parser

Well if you don't do that, you would only have a lowest common denominator system with none of the advanced features, and the world has enough of those. If I wanted to emulate a fraction of org-mode features I use daily in markdown, I would have to use Obsidian with a bunch of plugins, and we would end up in same boat. I don't know the exact spec situation, but I know that comprehensive parsing libraries in modern non-elisp languages exist. An org-mode contributor has one in Julia[1], another in Dart[2] that powers a Flutter app, and there are many tree-sitter grammar based tools that are useable from neovim (e.g. [3]). The basic org2html or org2pdf CLI needs are already addressed by Pandoc. [1] https://github.com/tecosaur/Org.jl [2] https://github.com/amake/org_parser [3] https://github.com/nvim-orgmode/orgmode

Hi. That author was me, but my app is Orgro (https://orgro.org), not Orgzly. The relevant libraries are https://github.com/amake/org_flutter and https://github.com/amake/org_parser.

I had a great experience using PetitParser (https://github.com/petitparser) in Dart, though it turned out my use case was a bit hairy for combinatorial parsing: I made a parser for org-mode (https://orgmode.org/) markup, which is similar to Markdown. Markdown-like formats are quite line-oriented and sometimes context-sensitive in ways that make rules hard to express. I did get something usable, but I had to make some new primitives and break some efficiency rules (copying substrings). The result is here: https://github.com/amake/org_parser (Shameless plug) It’s used in my FOSS mobile org-mode viewer app Orgro: https://orgro.org
