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.

Bash functions are better than I thought
At one time, I did learn myself to write shell scripts. I even wrote this 3Kl line monstrosity [0]
However, I would strongly advice to master a proper programming language. I respect the article and the efforts of the author, but I feel that it is the past.
I mastered Python a bit and the ability to just use things like dictionaries, proper parsing libraries and such, instead of kilometers of fragile pipes, it is so much better.
I understand something like Python may feel total overkill, but that 10 line shell script suddenly needs quite a bit of error handling and some other features and before you know it, you wish you started out with python or something similar.

> there isn't really an entry point in murex scripts
I have a nice trick in NGS for that. Under the idea that "small scripts should not suffer", script is running top to bottom without "entry point". However, if the script has defined main() function, it is invoked (with command line arguments passed).

> `args` still contains more boilerplate code than I'm happy with
Is there anything preventing you to have exactly the same functionality but with syntactic sugar that it looks like parameters declaration? (Just to be clear, keeping all the ARGV machinery).
Something like (assuming local variables are supported; if not, it could still be $args[Flags] etc):

No, you can't do it better in Python or bash (challenge)
Doing DevOps today? 99% either abuse bash or abuse a general purpose programming language.
bash does not meet any modern expectations from a programming language: syntax, error handling, data structures
General purpose languages such as Python, Ruby, etc are not domain specific enough to have the desired facilities.
Here is small example of straightforward solution to a small problem: list all CloudFormation stacks that are managed by the given CodePipeline.
