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.
gram_grep
-
AST-grep(sg) is a CLI tool for code structural search, lint, and rewriting
There is also gram_grep[0]"Search text using a grammar, lexer, or straight regex. Chain searches for greater refinement."
See also parsertl-playground[1] for online edit/test grammars.

Show HN: Yacc/Lex editor/tester online
I'm building an online yacc/lex (LALR(1)) grammar editor/tester to help develop/debug/document grammars, the main repository is here https://github.com/mingodad/parsertl-playground and the online playground with several non trivial examples is here https://mingodad.github.io/parsertl-playground/playground/ .
Select a grammar/example from "Examples" select box and then click "Parse" to see a parser tree for the source in "Input source" editor.
It's based on https://github.com/BenHanson/gram_grep and https://github.com/BenHanson/lexertl14 .
Any feedback is welcome !
The grammars available so far (with varying state of correctness):
- Ada parser
- Question about lexer and parser generators in Rust

Thanks for the tip, but I fear storing the result on the stack will be too much to ask for for big lexers (see https://github.com/BenHanson/gram_grep/blob/c64f8829661f11b38a55b42b37f5051c5eabfaa6/main.cpp#L2301 for example).

Ask HN: What apps have you created for your own use?
It's currently whitelist-based [0]. The downside is larger (code) size. The upside is simplicity. I imagine a blacklist could also work well, at smaller size but with more preprocessing needed.

Wow! What a coincidence. Just the other day I finished "v1" of a similar tool: https://github.com/alexpovel/srgn , calling it a combination of tr/sed, ripgrep and tree-sitter.
I've spent a lot of time trying to find similar tools, and even list them in the README, but `AST-grep` did not come up! I was a bit confused, as I was sure such a thing must exist already. AST-grep looks much more capable and dynamic, great work.
