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.

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

MSVC Backend Updates in Visual Studio 2019 version 16.10 Preview 2 | C++ Team Blog
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).
