Hi everybody,
I have just released ocaml-pandoc, a native OCaml library to write filters for pandoc, which is a markdown-to-anything converter. It has allowed me to write some simple filters I needed (such as for including code snippets, which is not supported natively).
The support is not complete yet however, I might add more if needed (and pull-requests are of course accepted 
).
This is awesome. Consider announcing this on haskell discourse as well.
Sounds interesting. Last time I wanted a Pandoc filter, I made it in Lua because it was the simplest and most performant thing to do.
Do they promise AST format stability and how stable is it in practice?
I don’t know for sure how stable the AST is (the only solid documentation I could get is from the Haskell library), but it does not seem to be changing much.
