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 - Akwa parser (not working) - Aliceml parser (partially working) - Ansi C11 parser (partially working) - Ansi C18 parser (partially working) - Ansi C parser - Antlr4.5 parser - Bison parser (partially working) - Blawn parser - Braille parser (not working) - C3c parser - Calculator parser - Carbon parser (need review of '*') - Chapel parser - CocoR parser (partially working) - Cpp5-v2 parser (not working) - Cql parser - Cxx parser (not working) - Doxygen code scanner torture - Ecere parser (not working) - GramGrep parser - HTML parser - idl2cpp parser - Ispc parser - Java11 parser - JavascriptCore parser - Jq parser (partially working) - Json5 parser - Json lexer - Json parser - LALR parser - Lark parser - Lezer parser (partially working) - LFortran parser (partially working) - Linden Script parser - Lox parser - LPegrex parser (partially working) - LPython parser (not working) - Lua2ljs parser - Lua-5.3 parser - Lua parser - LuaPP parser (partially working) - Minic parser - Minizinc parser (not working) - MSTA parser - Mulang parser (not working) - Openscad parser (partially working) - Peg parser (partially working) - Pikchr parser - Playground3 parser - Playground parser - PnetC parser - PnetCSHarp parser - PnetDPas parser - PnetJava parser - PnetVBasic parser - Postgresql parser (be patient) - Preprocessor parser (not working) - Rust parser - Scheme parser - Souffle parser - Tameparse parser (not working) - Textdiagram parser - Textmapper parser - Webassembly interpreter parser - XML parser - Z80 assembler parser
