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
- Why no more Lex/Yakk/ANTLR/whatever?
lexy
-
Why are strings and IO so complicated?

Koji projekat na Githubu vas je odusevio u zadnje vreme?
https://github.com/foonathan/lexy nakon sto sam se propatio sa errorima od boost spirita, a pegtl mi se nije svidao, ovaj library je dosao kao odusevljenje, a i dokumentacija je iznenadujuce ok

Simple question on compilers and syntax rules
In general, LALR parser generators are more difficult to work with than RD parser combinators. Instead of flex and bison, I'd recommend checking out Boost.Spirit or lexy.

How often do you use these keywords ?
lexy has something like std::bind with a way to specify fallback values for the placeholders if the arguments aren't provided: lexy::_1.or_default(fallback)
