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.

App init and graceful watch lib recommendations ?
For configuration, I like Koanf.
-
Two ways to provide configuration: command-line, yaml file.
Of course. You should always use a good config package. caarlos0/env is okay but https://github.com/knadh/koanf is a better all around solution imo.

Golang equivalent of Python’s click (CLT framework)
You can also use Viper with urfave/cli, or you can replace Viper with knadh/koanf, which I personally prefer.

Viper – Go Configuration with Fangs
Use viper with care. It has some dangerous fundamental flaws [1]. We got bitten hard, submitted a PR [2] and followed up for a year and a half to no avail, before I went ahead and reinvented the wheel and wrote koanf (plug), specifically to avoid viper's flaws.
Most importantly:
- Breaks JSON, YAML, TOML etc. language specs by forcibly lowercasing all keys internally. Dangerous because it can silently merge differently cased config keys into lowercase.
- Hard codes big unnecessary dependencies into the core, significantly bloating build sizes. No separation or abstraction.

Extracting embedded files
It's not hard to a) look for a key in an environment variable b) accept a key as a parameter c) load a key from a file d) all of the above with something like koanf

Coral, a friendly Cobra fork with nearly all its features, but only 4 dependencies
Came across this the other day https://github.com/knadh/koanf as an alternative to Viper.
-
What are your favorite packages to use?
https://github.com/knadh/koanf for config management. Readme contains why it's a good alternative to viper.

climate "CLI Mate": a CLI library that autogenerates CLIs from structs / functions with support for nested subcommands, global / local flags, help generation from godocs, typo suggestions, shell completion and more
I’ve been using https://github.com/alecthomas/kong for exposing generated protobuf structs for CLI args. How does your library compare?
-
Which packages do you recommend for building cli tools?
I prefer https://github.com/alecthomas/kong these days
- I'm looking for a library that can parse through a string and pickup parameters and add it to a golang object

Coral, a friendly Cobra fork with nearly all its features, but only 4 dependencies
We switched all our cli tools from cobra/viper to kong. I can highly recommend it. Almost no deps and easy to use, a great replacement for cobra in my opinion.
-
Recommended framework/library for creating cli apps in go?
I switched all from viper to kong.

I'm looking for a good alternativ to Viper
For all my commandline parsing and config loading needs I use kong. In contrast to Viper and Cobra it has almost no dependencies (while viper and cobra pull in half a jungle).
-
Made my first command-line tool with Golang
I think it is probably just a matter of personal taste, but I like to handle params and flags on the main function. I am probably biased by C experience and using https://github.com/alecthomas/kong though. Kong is certainly not as popular as cobra, but its approach.
