polars-ocaml is a project to provide idiomatic OCaml bindings to the Polars dataframe library.

Check out the ported examples from the Polars user guide for a quick tour of what you can do with polars-ocaml!

Install with opam install polars.

Currently very much WIP. Please expect breakages and large changes in API.

Note that the current code assumes that the OCaml version is 4.14.1; see HACKING.md for notes on how to build polars-ocaml.

odoc-generated docs are available here.

polars-ocaml works in utop!

$ dune utop --profile utop¹

polars-ocaml works in Jupyter notebooks, using akabe/ocaml-jupyter!

Just install the polars opam package alongside the jupyter package:

$ pip install jupyter
$ opam install jupyter polars
$ ocaml-jupyter-opam-genspec
$ jupyter kernelspec install --user --name "ocaml-jupyter-$(opam var switch)" "$(opam var share)/jupyter"
