Hi folks, thanks for all the feedback; I got distracted with other stuff today so I didn't manage to push the changes but I hope I will do ASAP.

I'd like to mention that the Python bindings for SerAPI are actually quite ready I think as a prototype, so this could save some people a bit of plumbing work I think; they were blocked by a problem with ppx_python but I think that's solved now.

So if you plan to interact with SerAPI from Python you should be able to give the branch a go soon [current branch on github I think is broken due to the ppx problem so I need to update it]

Oh, that's very exciting! Does this save on serialization/deserialization time? In the Alectryon paper I measured that about 1/3 of the runtime was spend parsing and unparsing sexps.

Good question, should be faster but I dunno how much, as still we have the OCaml -> Python conversion and vice-versa; I am not very familiar with the internals of ppx_python .

There are still a few issues to be solved, in particular w.r.t. how to best map some notions / Coq APIs to Python, but the basic things should work.

Sweet. Let me know when I should give it a spin (though it'll take me a few weeks to catch up with my current stuff)

Ok, got it working https://github.com/ejgallego/coq-serapi/blob/v8.13%2Bpyml/test.py

Still many things to improve, and I have 0 Python knowledge so indeed you folks who are Python experts should help to frame the API as you would like it

Will post instructions in the corresponding issue https://github.com/ejgallego/coq-serapi/issues/48

Ok I put the instructions on a draft PR https://github.com/ejgallego/coq-serapi/pull/240

Hi folks, something I'll need help here is with regards to Python packaging; the way I will proceed is that once the required deps for coq-serapi + python is ready, the opam package will install the corresponding .so that can be loaded by python, but no idea how to sync that to the particular python code that I'd assume grow large over time.

I'm curious, what is the differences between emilio's PyCoq and Proverbot's coq_serapy interface https://github.com/HazardousPeach/coq_serapy/tree/main ?

How will the interface to python interface to coq (https://github.com/ejgallego/pycoq) change when a language server is used? asking due to following line:

Note: In future versions, sentence id will be deprecated, and instead we will use Language Server Protocol-style locations inside the document to identify sentences.

(I assume this will change the interface to SerAPI and not only PyCoq-SerApi? Since we won't be able to send documents seperated by dots etc anymore?)
