Feature request: Inlay hint

[fecet]

python still don't have avaliable language server support inlay hint, hope pylsp can be the hero 😄

Hey @fecet, thanks for reporting. What do you mean by this?

[fecet]

The inlay hint feature is stabilized in latest LSP Spec 3.17, and implemented in VSCode and Neovim.

Currently pylsp doesn't support that

Just as a note - inlay hints are supported by coc-pyright and VSCode's pylance, but notably not pyright (although I don't use either pylance, which requires VSCode, or coc-pyright).

based-pyright supports inlay hints

Just as a note - inlay hints are supported by coc-pyright and VSCode's pylance, but notably not pyright.

I don't know coc-pyright approach, but:

• VSCode's Pylance is not possible to make it work. It has proprietary licensing and does some checks against Microsoft's marketplace, that even VSCodium staff are having issues in giving the support for running outside VSCode.
• VSCode's Pyright won't have the feature. Microsoft has chopped that functionality out, in favor of adding that to Pylance. Pylance and Pyright are, some how complimentary. Pyright does only type validation.

As @markis said, BasedPyright project supports that. And it's even more accessible for Python developers, since doesn't force users to install NodeJS (like coc-pyright o pyright require). It does install NodeJS behind the curtains though, but it's all encapsulated in a virtual environment, transparent to the Python developer.

Yeah, at this point i would definitely recommend basedpyright. It didn't exist at the time I made my comment lol
