Formatting and diagnostics for Puppet in Neovim

[pauljacobson]

Hi everyone 👋

I've started learning about configuration management using Puppet. Puppet uses configuration files that (I think) use the file extension .pp.

I also use null-ls.nvim for LSP support in Neovim. I believe that null-ls has builtin support for Puppet. I'm just unsure how to configure Neovim to give me syntax highlighting and linting/diagnostics for Puppet files.

Has anyone set this up? If so, can anyone point me in the right direction?

Syntax highlighting isn't something we support yet, but it looks like we have sources for diagnostics and formatting using puppet-lint. You can see the README and the built-in documentation to learn how to set them up and use them, but the minimal config you'll need to register them is this:

local null_ls = require("null-ls")

null_ls.setup({
    sources = {
        null_ls.builtins.diagnostics.puppet_lint,
        null_ls.builtins.formatting.puppet_lint,
    },
})

Also, for whatever reason these sources aren't in the documentation I linked above. If you successfully set them up, a PR to update the documentation would be greatly appreciated.

Thank you very much @jose-elias-alvarez

@jose-elias-alvarez or @pauljacobson, just a noob question here?

Where would I need to add this snippet to make this thing work on neovim or even better lunarvim?
Is it init.lua for neovim or config.lua for lunarvim?

local null_ls = require("null-ls")

null_ls.setup({
    sources = {
        null_ls.builtins.diagnostics.puppet_lint,
        null_ls.builtins.formatting.puppet_lint,
    },
})
