Online yacc/lex grammar editor/tester

[mingodad]

I'm trying to build 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 !
