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.

AST-grep(sg) is a CLI tool for code structural search, lint, and rewriting
Hi, ast-grep author here. This is a great question and I asked this in the first place before I started the hobby project.
TLDR; I designed ast-grep to be on different tracks than semgrep.
Semgrep is for security and ast-grep is for development.
First and foremost, I have always been in awe of semgrep. Semgrep's documentation, product sites and Padioleau's podcast all gave me a lot of inspiration. Using code to find code is such a cool idea that I never need to craft an intricate regex or write a lengthy AST program. sgrep and patch from https://github.com/facebookarchive/pfff/wiki/Sgrep have helped me a lot in real large codebases.
When I used semgrep as a software engineer, instead of a security researcher, I found semgrep has not touched too much on routine development works. I can use `semgrep -e PATTERN` but the Python wrapper is not too fast compared to grep.

What's wrong with static-analysis autofix/codemod tools? Why don't we use them more, across the industry? What's your experience?
Over the decades, there's been so very many attempts to address this conundrum; and yet, ...
