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.

A Deep Dive into PromQL — Promql Parser v0.1.0 Written in Rust is Now Available
prometheus-parser-rs implement the parser via pest, while promql-parser using grmtools, which is compatible with Yacc. promql-parser declares compatible with prometheus and covers most of the test cases in original Prometheus, which ensures you better compliance.

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
What are some alternatives?
c-compiler - A compiler that accepts any valid program written in C. It is made using Lex and Yacc. Returns a symbol table, parse tree, annotated syntax tree and intermediate code.
