dhall-lang VS drone

Fail to see how this is any different than Dhall (https://dhall-lang.org/) other than it produces plists too.

Kubernetes config is a decent example. I had ChatGPT generate a representative silly example -- the content doesn't matter so much as the structure:

https://gist.github.com/cstrahan/528b00cd5c3a22e3d8f057bb1a7...

Now consider 100s (if not 1000s) of such files.

I haven't given Pkl an in depth look yet, but I can say that the Industry Standard™ of "simple YAML" + string substitution (with delicate, error prone indentation -- since YAML is indentation sensitive) is easily beat by any of:

- https://jsonnet.org/

- https://nickel-lang.org/

- https://nixos.org/manual/nix/stable/language/index.html

- https://dhall-lang.org/

- (insert many more here, probably including Pkl)

There are underpowered languages / tools, that can only solve a problem for which they are intended poorly. But not all limited tools are like that.

Say, eBPF is prominently not Turing-complete, which allows to guarantee that a eBPF program terminates, and even how soon. Still eBPF is hugely useful in its area.

Or, say, regular expressions are limited to regular languages; in particular, they famously [1] cannot process recursive structures, like trees. Still tools like grep / ag / rg are mightily useful.

Yes, I agree that YAML is underpowered for proper k8s configuration! But it's also too powerful for its own good in other aspects [2]. I wish Google used Dhall [3] or their own purely functional config language (FCL? I already forgot the name) instead of YAML; sadly, they did not.

Dhall: Dhall is a programmable configuration language that combines features like JSON, functions, types, and import capabilities. Its style leans towards functional programming, so if you're familiar with functional-style languages such as Haskell, you might find Dhall to be quite intuitive.

I've been thinking along these lines but more 'strongly validated' than statically typed in the sense that you'd be better off being able to load the entire config and then produce a list of problems (and should be able to offer good editor support if done correctly).

Though https://dhall-lang.org/ demonstrates that you can statically type quite a lot of configuration to great advantage, which appears to be programmatically embeddable in multiple languages per https://docs.dhall-lang.org/howtos/How-to-integrate-Dhall.ht...

Configuration processing. E.g. I'd like my yamls to be decidable, though I'd settle for guaranteed to halt[1].

Maybe you'd like jsonnet: https://jsonnet.org/

I find it particularly useful for configurations that often have repeated boilerplate, like ansible playbooks or deploying a bunch of "similar-but" services to kubernetes (with https://tanka.dev).

Dhall is also quite interesting, with some tradeoffs: https://dhall-lang.org/

A few years ago I did a small comparison by re-implementing one of my simpler ansible playbooks: https://github.com/retzkek/ansible-dhall-jsonnet

Drone (https://github.com/harness/drone) shell's all codes are deleted and replaced with new project (gitness) to retain Github Stars. What do you think?

I went to check on this, and it seems that https://github.com/harness/drone redirects to harness/gitness. I'm now very confused.

You can check the drone license or sentry license.

To use github my code would have to leave my server. I can build it myself using woodpecker. I used drone.io till they were bought out and went closed source then migrated to woodpecker-ci

A lot of people on reddit seem to recommend gitlab, or drone.io, but if you get on indeed and search for jobs there are tens of thousands of posts looking for people who know Jenkins and only a tiny fraction of job listings interested in any other ci framework. Is it worth investing time into anything else? It's my decision and while the other options seem more friendly I don't see any point in learning them if I'm not going to be able to use them in the future.

I personally use drone CI (https://drone.io) with the DroneExternalConfig plugin (https://github.com/0x1a8510f2/DroneExternalConfig).

Gitea + drone.io is what I am using. Very happy with the solution.

No 5000 build limit if you use Gitea/Gogs Ref: https://github.com/harness/drone/blob/master/service/license/load.go

I really should migrate to Gitea + drone.io

I'm really embarassed to say that I love docker-compose over K8s for its simplicity & effectiveness.But tools are reallly lacking.drone.io is like a docker-compose.yml. Simple, effictive & beautiful.
