#cuelang — Public Fediverse posts

I'm at #FOSDEM all weekend! Ping me to talk #cuelang or #golang :)

I'll be at #FOSDEM next week! Haven't been since 2014, which feels like a lifetime ago. If we have met or collaborated in the past, or you'd like to say hi, my DMs are open :) #golang #cuelang

I am down the rabbit hole of melding #golang and #cuelang with a dash of #peg and a twist of #TextMate tmLanguage.json (but using RE2 not Oniguruma for reasons)

I have a problem. Need to validate config file
Using #cuelang
Now I have 2 errors in empty disjunction problems

I'll be speaking at GopherCon UK in London this August! Comment below or drop me a message if you'd like to chat about #cuelang or #golang :) Odd that they're not posting on Bluesky though - such a missed opportunity.

@jonathanmatthews 100%.

I been trying to convince people to use #cuelang anytime they are yaml programming. But practice has been people still "like" yaml cause that's what they know. 🫠 Fully misunderstanding what a data value validity brings instead to your sanity. 😅

@CleoMenezesJr Most of my #GTK app wishlist is either #GTK4 modernization or new features for existing apps...mainly #SelfHosted server sync. Would be nice to login to #Nextcloud via GOA & have a solid client for each NC app.

Outside of that:

- Database viewer / query runner
- REST API tester
- #ActivityPub tester
- Clients for various fediverse servers
- #JSONSchema / #Cuelang / #Nickel contract validator
- GIF search
- GitHub / #Forgejo Actions manager & runner
- #systemd unit manager

New #cuelang goodies dropped: https://github.com/cue-lang/cue/releases/tag/v0.9.0

@lawouach I see, recently I also took a look at #cuelang #dhalllang and #jsonnet but for a team that is not coming from a functional programming background with not a lot seniority, #helm still seems more appealing, even without considering the ubiquity of it. Or that was the impression that I got.

OH: You sprinkled some #cuelang on it!

Current status: Learning cue and using it in anger (the good kind). #cuelang

Thinking about #kustomize that would excel in #declarative programming and overlays vs Helm...

What about using general purpose functional programming? Using a YAML type provider in #fsharp can provide strong typing for YAML configuration files, making it easier to work with YAML data in a more type-safe manner. It would be more familiar to me than #cuelang.

Well, the combination of #golang and #cuelang appears to be the most common choice.

Now hearing from Rog Peppe about the Cue language here at @golab #golang #CueLang

I only learned properly a couple of weeks back about how elegant #CUE's multi-for-loop construct is!

Because in #ConfigMgmt land we're /so/ often dealing with spiky, nested objects, the nested "for" loop has a lovely indent-saving form: here, the loop starting on L37 incorporates 3 for elements, 1 "if" guard, & 1 additional temporary allocation ("let"), whilst letting me iterate over the /innermost/ elements of a (resource|data).<level1>.<level2> shaped struct 🙂

#cuelang is genuinely awesome!

As much as I love "diagrams as code", what I actually want is"diagrams as data" so I can both generate visual output and do calculations.

This is a fascinating example:

Does anyone now the status of using #cuelang for @grafana dashboards? There have been various issues, PRs and experiments over the last couple of years, but the current state still seems unclear.

Someone needs to replace #helm with something #cuelang based

#CueLang makes it very easy and elegant to add #monitoring to your system (in this example exposing @Prometheus scrape endpoints) across environments and deployments, with templating, validation, defaults and even enforcement.
Good talk by #CueLang creator Marcel van Lohuizen

It’s worth spending the time to make your code as easy to maintain and update. You might not be the one troubleshooting in an emergency. #cuelang #CfgMgmtCamp

I'm putting out some short and uncomplicated videos on my favourite thing at the moment: CUE!

#Cuelang is a smart #data #constraint #language that /looks/ a bit #JSON shaped, but is actually going to save us all from the dreary, #YaML-esque future that /feels/ so inevitable!

Here's a really short video I've just published about a fantastic CUE feature that lets us combine #schemas and concrete values, separately but hierarchically, organising instances in parallel: https://www.youtube.com/watch?v=OaPLbvHpVlc

@dirsigler Nothing against it exactly, but this is for a toy project and I've been looking for an opportunity to play with #cuelang for a while, and this has been the first thing that I've needed a structured config file for in a while, so it seemed like a good fit.

So, I need a config file for my toy project in #golang. Nothing terribly fancy, but there's some structure to it that makes TOML, etc unnatural. So I figured I'd play with #cuelang, and then have my code read either a YAML or JSON file, process it against my Cue definition, and use the result.

I have it working fine with 'cue eval'. Feels pretty reasonable, actually. So I tried to add it to my code and... I can't even figure out where to start.

"Cuelang.org, while taking a moment to fully appreciate, is a fantastic tool to unify all those with automation build in and effortless value type based schema. Highly recommended."

For the curious: CUE is a language for defining, generating, and validating data. Written in Go but useful for everyone. (That is, it's not specific to Go.)
