dhall-kubernetes VS nvim-lspconfig

I hate yaml with a passion. It marginally better than xml for reading (wins huge on comment syntax) and worse for everything else. It makes zero sense we somehow ended up with it as standard configuration serialization format.

Note yaml is not a DSL. It's a tree serialization format! Everything interesting is happening after it is parsed. Extreme examples point to e.g. github actions conditions.

Anyway, back on topic - maybe not prolog for CDK, but still quite interesting: Dhall-kubernetes - https://github.com/dhall-lang/dhall-kubernetes

At this point, if it’s painful enough, why isn’t compiling-to-yml tools more popular?

Example: https://github.com/dhall-lang/dhall-kubernetes

Haven’t used dhall myself but I’d definitely prefer a DSL on top of yaml.

Dhall provides https://github.com/dhall-lang/dhall-kubernetes which is exactly this: statically type-checked kubernetes config generation.

Dhall is my favorite configuration language that I never get around to using.

I manage DNS in Terraform, and since every Terraform provider uses different objects definitions, and every object definition is rather verbose, Dhall would be a way to specify my own DRY types and leave the provider-specific details in one place. Adding new DNS entries and moving several domains between providers would be a matter of changing fewer lines.

Dhall also has Kubernetes bindings:

Although I'm tempted to just stick to Helm here, even though it's less type-safe.

Not Helm directly, but does something like Dhall fit your question? https://github.com/dhall-lang/dhall-kubernetes

Have you heard about Dhall? It’s a programming language used for generating configuration files for a variety of purposes. One of them is to replace old and limited formats such as JSON and YAML. It is DRYable, secure, and even suitable for creating K8s manifests. The latter option isn’t something for anyone: you have to learn a new language and deal with its peculiarities, but it might be really helpful when you have tons of YAML configs. I’ve recently made a short intro to Dhall for K8s in this review.

Best thing is Dhall that I am aware of. Same situation, working as a consultant, forced to use broken things.

https://github.com/dhall-lang/dhall-kubernetes

Lets look at a specific example. Take Kubernetes: everything is yaml, with complete schemas, all the way down. From your perspective this is configuration utopia, right? Meanwhile back in reality k8s is the poster child of "yaml hell". From the day it was released, people took one look at it, gave it a giant NOPE and instantly spawned half a dozen templating languages. The most popular of these is helm, which has a terrible, no good, very bad design: full of potential injection attacks from purely textual string substitution, manually specified indentation to embed parameterized blocks, virtually no intermediate validation, no way to validate unused features, etc etc

Compare to dhall which publishes a complete set of dhall-k8s schema mappings which enables you to factor out any design you want down to as few configuration variables as you like, while validating the configuration generators themselves at design time. https://github.com/dhall-lang/dhall-kubernetes#more-modular-...

The solution I like is Dhall. They even have a Kubernetes solution that will catch a lot of issues at compile-time, before you try to apply it to Kubernetes. At earthly we aren't actually using it though. Our Kubernetes guru found it to be a bit slow but I am hopeful it or something like it will be the future.

I suggest looking for blog posts about this, you're gunnuh wanna pick out a plugin manager and stuff. It's kind of like a package manager for neovim. You can install everything manually but usually you manually install a plugin manager and it gives you commands to manage the rest of your plugins.

These two plugins are the bare minimum in my view.

https://github.com/nvim-treesitter/nvim-treesitter

Treesitter gives you much better syntax highlighting based on a parser for a given language.

https://github.com/neovim/nvim-lspconfig

This plugin helps you connect to a given language LSP quickly with sensible defaults. You more or less pick your language from here and copy paste a snippet, and then install the relevant LSP:

https://github.com/neovim/nvim-lspconfig/blob/master/doc/ser...

For Python you'll want pylsp. For JavaScript it will depend on what frontend framework you're using, I probably can't help you there.

pylsp itself takes some plugins and you'll probably want them. https://github.com/python-lsp/python-lsp-server

Best of luck! Happy hacking.

Adding language support it neovim isn't very difficult once you're setup. I use nvim-lspconfig[1] and just about any language you could need is documented[2]. But like others have mentioned there are batteries included distributions of neovim if that's your cup of tea.

[2]: https://github.com/neovim/nvim-lspconfig/blob/master/doc/ser...

If we can't find the basic usage in the documentation we can go to nvim-lspconfig's github repository. In there we look for a folder called server_configurations, this contains configuration files for a bunch of language servers.

https://github.com/hrsh7th/nvim-cmp This is an autocompletion engine https://github.com/nvim-treesitter/nvim-treesitter This allows NeoVim to install parsing scripts so NeoVim can do things like code highlighting. https://github.com/williamboman/mason.nvim Not strictly necessary, but allows you to access a repo of LSP, install them, and configure them for without you actively messing about in config files. https://github.com/neovim/nvim-lspconfig Also not strictly necessary, but vastly simplifies LSP setup. https://github.com/williamboman/mason-lspconfig.nvim This lets the above two plugins talk to each other more easily.

This specific issue talks about fixing clangd for that error: https://github.com/neovim/nvim-lspconfig/issues/2184. The issue is ongoing for ccls AFAIK but for clangd, this has been discussed and fixed in the past already.

I am trying to set up the pbkit language server for protobuf files. Since it is not part of the nvim-lspconfig repo's server configurations, I have to figure the way out myself. It doesn't seem to be too difficult, as I can start from the bufls configuration there. The following is what I have at the moment:

I have configured neovim with lspconfig and mason. Added the suggested configuration of the lsp config(https://github.com/neovim/nvim-lspconfig) to ~/.config/nvim/after/plugin/lsp.lua Then I installed via mason the following language servers:

Personally, i think nvim-lint is the best alternative currently, specially so because it has no dependencies on external binaries. This guide assumes you already have your LSP set up with nvim-lspconfig (or an alternative like lsp-zero). You should also have an way to install the linters you are gonna need, i highly recommend Mason with mason-lspconfig.

Basically neovim can act as a client to a variety of different language servers (https://github.com/neovim/nvim-lspconfig/blob/master/doc/ser...) which give neovim IDE capabilities. This can be done in original Vim also but requires external plugins which can be a pain to compile and install. Neovim has it built in.

I'm struggling to get [sqlls](https://github.com/joe-re/sql-language-server) with [nvim-lspconfig](https://github.com/neovim/nvim-lspconfig) to use Postgres syntax.
