dhall-kubernetes VS coc.nvim

One thing that might help you in this madness is:

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

Type safe, fat finger safe representation of your YAMLs is grossly underrated.

At the moment nothing like that exists. Eventually it should be possible to generate RCL types like https://github.com/dhall-lang/dhall-kubernetes does for Dhall.

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-...

Neovim comes with a client. For Vim you will need to install one, such as CoC, LanguageClient-neovim, or vim-lsp.

👉 With LSP in this installation, I use Coc for its simplicity without the need to intervene in the Coc configuration. LSP has been very useful in my Helix modal editor to configure Helixu.

As well as its own plugins Vim/NeoVim can use VSCode's LSPs, DAPs and extensions either directly or via plugins like CoC[1] and Mason[2].

I would be surprised if emacs couldn't do the same.

1. https://github.com/neoclide/coc.nvim

The most famous TypeScript one probably is coc.nvim

It is flatly the wrong mindset to think of vim as an IDE. vim is a code editor: get in, make change, get out. Consider vim koans, which are a fun little read. You can throw coc.nvim at Neovim, along with a few other bits to give you a Good Enough setup, but vim isn't and will never be an IDE.

I just did a fresh reinstall of CoC, on a newer version of Neovim. I'm now seeing something I hadn't seen before, which CoC calls "inlay hints". They look like this:

I'm currently on an old setup (using coc and polyglot) and nvim v0.6.1. I'll be updating to a more modern setup within next year, using the native lsp and building nvim more frequently. But that's not today.

coc.nvim

There are some plugins which have the best documentations I have ever seen, but you need to read it from the Vim.

Example of coc.nvim: https://github.com/neoclide/coc.nvim/blob/master/doc/coc.txt

Actually you can with coc.nvim & coc-sh. So long as shellcheck is also installed and in PATH, it'll integrate with coc/vim just fine.
