Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Show HN: Togomak – declarative pipeline orchestrator based on HCL and Terraform
I am looking forward to a mix of both - I am hoping to add a concept called "operator" which would be a go-plugin [1], just like terraform providers, but build backends. So, someone would be able to, say, write a Slack plugin (in Go, or anything over RPC) which sends a message once a build is complete - like Jenkins/GitHub actions, or just scripts that we can reuse like GitLab CI through `modules`.
Perhaps a new registry where we can push custom modules and providers (operators in this case), I'm curious to know about if we have any existing implementations we could reuse for the registry.

referencing packages on the internet and using go plugin
I'd recommend looking into a different approach for plugins such as hashicorp/go-plugin (which uses multiple process PIDs and RPC communication between them) or traefik/yaegi (which implements a Go-compatible scripting language that can be interpreted at runtime and which still supports most Go modules).
- Can Go dynamically load library module at runtime?
-
Binary packages alternative
You'll never fully protect your code from someone who's dead-set on reverse-engineering it, however, you can use https://github.com/hashicorp/go-plugin or a similar RPC technique, which will let you ship binary plugins and will also be less fragile and janky compared to something made with `-buildmode=plugin`.
-
How would you guys support plugins in a Go app? (or any other compiled language for that matter)
The plugin system that hashicorp uses for all their projects works very well. It's essentially a local RPC implementation. https://github.com/hashicorp/go-plugin
-
Change go code behaviour at runtime
The leader is almost for certain https://github.com/hashicorp/go-plugin which uses RPC. This prevents some of the binary compatibility issues from the standard library option, operating system issues from the standard library option, and it is in use by lots of large projects from Terraform to Packer, Nomad, and Vault.
-
Is the documentation for making non-go plugins in the go-plugin repo outdated?
can you try older go-plugin versions? The only major change in v1.4.4 was a bugfix for automtls. https://github.com/hashicorp/go-plugin/blob/master/CHANGELOG.md

Making Games in Go for Absolute Beginners
> I am the developer of Astral Divide, which is entirely written in Go: https://store.steampowered.com/app/2597060/Astral_Divide/
Your game looks great, congrats on your progress! I especially enjoyed how the zoom works when you're leaving/arrive planets, and the unique propulsion system (also, the anchor made me giggle!).
> lack of data structure packages
I tend to not need many, so I'd be curious if you can recall any structure in particular which you couldn't find? No biggie if not.
> package structure not suited for games
I'm not a game dev, but I've seen some larger games such as https://github.com/divVerent/aaaaxy/tree/main/internal (if you haven't played it before—do it!) which seem to be able to place everything into separate packages without issue, so perhaps there's something to gleam from their design?
> maps are random when iterated
Hash map iteration shouldn't be sorted in _any_ language (here's Rust, for example https://play.rust-lang.org/?version=stable&mode=debug&editio... (Python makes it _appear_ as if dicts are sorted hash maps, but that's only because it doesn't only use a hash table, but a vector as well (same as you'd have to do in Go))), otherwise it would cause both portability and security (https://github.com/golang/go/issues/2630) issues. You can use a b-tree (which was probably the data structure you wanted there) if you aren't willing to sort it yourself.
> modding options
If you don't care about unloading https://github.com/pkujhd/goloader
Go actually has one of the best WASM runtimes https://github.com/tetratelabs/wazero
It also has a bunch of libraries for embedding scripting languages https://awesome-go.com/embeddable-scripting-languages, with Tengo _probably_ being quickest https://github.com/d5/tengo
I'd _highly_ recommend Ebitengine in the future, as not only have there been multiple brilliant games using it, but it also has Switch/Android/iOS support, and you can find help with any issue whatsoever in their Discord. People have built 3D games with it, and Hajime is an absolute beast of a developer.

Yes, I noticed those packages recently. The problem is that there is little data about how reliable and maintainable goloader is going to be on the long term.
As I care about performance and security, I don't want a scripting language, but WASM seems to be a very promising possibility. I have made benchmarks with 2~3 WASM engines in Go, and so far I am not completely convinced about the quality and performance of the available APIs. Also, when compiling Golang to WASM, the native compiler is still abysmally bad and does not have full support for imports, so Tinygo is a must-have.
Anyway, modding is still a long term idea at this point, so hopefully the ecosystem will get more mature within a couple of years.

Change go code behaviour at runtime
There are totally different things like https://github.com/d5/tengo but I don't know much about the docs, communities, or viability of them. Some like this one look very active and healthy. It might be worth considering.

Asking for advice to get deeper understanding of golang internals.
I started doing this a few years ago when I wanted to add programmability to another system I was working on, and didn't want Lua or anything else like that. I set it aside when other priorities arose, and didn't return to it when I saw that others had already done the same thing (yaegi, tengo).
