How to configure null-ls?

[NorseManGef]

I'm trying to setup null-ls, but I can't get the setup opts to work. I want to have null-ls run clang-tidy and clang-check, but I just can't figure out how to do it. Everything I've tried fails to build, stating that programs.nvf.settings.vim.lsp.null-ls.setupOpts.sources."[definition 1-entry 1]"' is not of type luaInline'`

I strongly urge you to avoid null-ls for formatting, linting and so on; nvf has had support for nvim-lint and conform for a while now, which are used internally and much better maintained by null-ls. Though, in the case you insist on using null-ls the solution is simple. You must define sources as raw lua code, which is done with mkLuaInline

vim.lsp.null-ls.setupOpts.sources = lib.mkLuaInline ''
	-- Everything in this string will be interpreted as raw lua!
'';

The above snippet should resolve the issue. If you are curious to why mkLuaInline is necessarry, it's because we need to identify between strings("nil") and lua code (mkLuaInline "nil"). Since Nix only has one string type*, the mkLuaInline function hints to the Nix -> Lua conversion helper that the code is raw lua, not a lua string.

Oh that makes sense. Thanks!

I tried to use nvim-lint initially but I couldn't get that to work
