starlark-go VS cuetorials.com

Starlark in go https://github.com/google/starlark-go is a great way to combine the best of both, the ease of use of Python and the simplicity of go.

I have been building a platform for deploying internal web applications using this approach https://github.com/claceio/clace. Use Starlark to configure the application, the platform itself is built in go.

The big unknown is your task definition: what does user-defined logic look like? If you're expecting go code, that's gonna need some cleverness because of the compiled nature of it. There's a node runtime implemented in go if you want to provide sandboxed javascript (check the source of k6.io, it's the main one I know that uses it). If you want to provide building blocks and let them compose them, starlark might be a good choice.

Another one of those (with broader language support) is the Starlark language, which has a Go implementation: https://github.com/google/starlark-go

Every config format gets as complex to be touring complete in the end. We had similar problems and eventually got rid of that complexity and switched to starlark (the bazel config language), was a huge benefit for the tools. https://github.com/google/starlark-go "Starlark is a dialect of Python intended for use as a configuration language. Like Python, it is an untyped dynamic language with high-level data types, first-class functions with lexical scope, and garbage collection."

Direct link to the Go implementation of Starlark: https://github.com/google/starlark-go

For a Python-like syntax, https://github.com/google/starlark-go is the language used in Babel. It's very mature, but since it is used in a massive mature project with a specific purpose, it doesn't move fast or drift from the spec of its Java-based sibling. It doesn't have exception try except blocks or some other features you might expect, but for short extension logic, it might be exactly what you want with the stability you can depend upon.

Context: https://github.com/google/starlark-go/blob/cfacd890221418a2dc2c736f7b5e3476c38709b1/starlark/int_posix64.go

Thus envd is more like Dockerfile, while it uses a simplified python dialect starlark https://github.com/google/starlark-go as the build language.

Use Go (mostly for starlark-go)

I have a website I maintain, many people tell me it has helped them

https://cuetorials.com

CUE(lang), because devops & yaml engineering has gotten out of hand

I maintain https://cuetorials.com and am heading up the CUE sig-infra group for the time being

If you need help with CUE(lang), we maintain https://cuetorials.com and have experience helping others adopt it at their companies

email is in my HN profile, same handle on GitHub and X

If you are more focused on the devops part, and not implementing a static site generator, then go with Python. For our static sites we use Hugo + GH Actions + Kubernetes (since we have a cluster anyway). There is not really any code involved here (example: https://github.com/hofstadter-io/cuetorials.com)

I'm personally interested to try https://docs.dagger.io/sdk/python/ for something. I used the CUE sdk, but it is effectively deprecated at this point. I use a mix of base, make, python, and CUE fro most devops / devex stuff now. Dagger makes it so local & CI stuff runs the same.

yup, I'm betting the proverbial ranch on CUE :]

I also maintain https://cuetorials.com

I also maintain https://cuetorials.com, bet the farm on CUE or something like that :]
