Neovim, Nix, Telescope, Tree-sitter, Mason

I made a mistake with not reading CHANGELOGs for all my packages in Neovim this week. This sent me down a small rabbit hole trying to fix all the things.

What happened is I ran :PackerUpdate which, pulls the latest version of Packer packages, good, updates! But... Telescope has a new requirement on main branch that requires Neovim 0.9.0. The problem is that the latest NixPkgs for Neovim right now is 0.8.1. I ran to google, tried to set an overlay to use neovim-nightly, but that didn't work. If you recall in Dotfiles - My 2022 Way I'm not actually using NixOS so (please correct me if I'm wrong) overlays don't work. I tried specifing a version in my programs.nix, I tried a bunch of other things at 1AM that I don't remember anymore.

Almost ripped it all out just to use Nvim 0.9.0 on this machine until NixPkgs has updated the repo. I decided that was the wrong idea, and went to sleep.

Tonight, I was able to figure out that in Packer, you can pin a commit!

It's clear in the docs, but I was trying to fix it at the Nix level, so I didn't immediately think of this, even though at my last job, Tidelift, I was doing package pinning analysis! Derp.

So, I added commit="c1a2af0" to my use statment in plugins.lua and Telescope started working again without a warning, or issue. Commit.

That wasn't the only problem though. In my infinite wisdom, I followed some reddit posts that I won't link to, that suggested deleting ~/.local/share/nvim and rerunning PackerInstall, the problem there -- my tree-sitter configs are in my nix files.

This is an issue I need to look at later, but in my programs.nix file, I some reason have two entries of plugins =. I had to uncomment the first one where I inject tree-sitter, and comment out the second setting. Then rebuild my nix flakes.

After that,I had to comment the first, uncomment the second, and rebuild with withAllGrammars config.

This worked, I had my rust tree-sitter configs working, but was missing rust-analyzer.

That's in Mason! So I ran :Mason, found rust-analyzer slapped that i button, and I finally had my system back after 2 days of issues.

This was mostly a blogpost so I can reference back to it in the future …
