The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
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.

Solving the Expression Problem in Go
Not diminishing the article at all, there's massive value I've gained from leveraging this runtime solution in multiple projects: https://github.com/antonmedv/expr
The language is easy enough for people to pick-up.
- Expr Release v1.15
- Expr v1.14 release: Go expression language
- Expr – expression language with type checker

FireScroll - The config database to deploy everywhere (now with conditional statements!)
Uses the [expr](https://github.com/antonmedv/expr) language to achieve this and I've been super happy with the results.

Library to analyze an arbitrary JSON string
I have been using expr (https://github.com/antonmedv/expr) to do something like this for a while. no complains so far.

[gcalc] A simple calculater in golang
If you wanted it to not require putting in the operation first and just accept string equations (without using something like https://github.com/antonmedv/expr) you could parse, tokenize and then process the input.

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

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
