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.

When will Go get sets?
I also wish that go had more common data structure in the stdlib. Recently created lib for sets: https://github.com/rutaka-n/genericset

Have you used generics?
Hey there! I've finally tried generics. In most cases, I do not need them in my projects, but recently I need set and decided to implement a generic data structure. https://github.com/rutaka-n/genericset Do you have any need to use generics? especially in project code, not a library.

An Efficient Struct Configuration Pattern For Golang
Funcopts aren't always appropriate, but boy do they make things more readable sometimes. I use them pervasively in warg to allow declarative nested CLI commands

Which packages do you recommend for building cli tools?
I wrote my own! https://github.com/bbkane/warg/

Major standard library changes in Go 1.20
Very useful! I'll be playing with the error tree additions and studying the HTTP interface extension to see if I can replicate the pattern for https://github.com/bbkane/warg values. Id like to be able to have value-specific output for different types of --help , even ones not in warg
-
Have you used generics?
I'm using to allow for custom flag types in my CLI parsing library- a lot less duplicate code

Go: Functional Options Are Slow
One thing that I find nicer with functional options is building tree-like data structures.
My command line parsing library uses them to declaratively build CLI apps with arbitrarily nested subcommands.
Some examples at https://github.com/bbkane/warg/tree/master/examples

How are YOU using generics so far?
I'm writing a CLI parsing library, and generics have let me consolidate most of the flag value functionality for different types. So the flags for dbz --level 9000 --type superSaiyan share most of the same code even though one is an int and one is a string. So much fewer copy-paste-modify lines of code now!

Unix command line conventions over time
This is largely what the Azure CLI does. It simplifies even further by eliminating the no-value option. Instead, you pass "true" or "false" as the value ( --example true ). It's a little more verbose but very easy to parse/write/generate. I like this convention so much I stole it for my homemade Golang CLI parsing library https://github.com/bbkane/warg/ .
