Find executable via `elan which` #305

Closed RaitoBezarius closed 11 months ago

RaitoBezarius commented 11 months ago

My system does not have any lean in the PATH of my NeoVim instance (I do this for any language to avoid pollution/confusion), generally, in Lean, we use elan as a switcher for the version we use, otherwise we can fallback to Lean.

I guess all that needs to do is to build a function inside of the _util.lua and replace all hardcoding of lean command to a lookup.

The default installation of elan though makes "fake" lean and lake binaries (which are aliases to elan). Are you saying you don't have those either?

RaitoBezarius commented 11 months ago

Ah right, I can inject those actually. Though, it still does not work "LSP is not connected" (I am using lspconfig) for some unknown reason, yet. Thank you!

Are you saying you're using lspconfig directly? You don't need to, lean.nvim will call setup for you -- you just need to pass the lsp object.

Even if I do so, the big issue I am having is that even if I am in the folder of the Lean project, filetype=lean is never autodetected properly even though I have a lakefile and a lean-toolchain and it's a file called .lean and I didn't touch the ft field.

Julian commented 11 months ago

Being in the folder of a Lean project isn't necessary for lean.nvim, it will detect the project root correctly -- if you don't have filetype detection working that sounds more like an install problem, how did you install lean.nvim?

RaitoBezarius commented 11 months ago

I installed lean.nvim via Nix / Home-Manager, CheckHealth is all green, my packdir which is loaded contains: https://clbin.com/nNtT2

Maybe, the build process change some months/years ago I guess?

RaitoBezarius commented 11 months ago

I feel like it's related to things with filetype.lua / filetype.nvim etc.
