Last time, I experimented with writing a flake that defined development environments for the esbonio package spanning multiple Python versions.
During that process I also packaged pytest-lsp using an ad-hoc nix expression as part of the esbonio repo.
In this post I look into writing a similar flake for the pytest-lsp package itself, but this time using overlays to override and extend the nixpkgs package set.
If you are interested, you can find the final version of the code
here.
