Grammar railroad diagram

[mingodad]

Using this tool https://www.bottlecaps.de/convert/ we can have a nice navigable railroad diagram (Syntax diagram) for sql.y.

Copy and paste sql.y on https://www.bottlecaps.de/convert/ Input grammar: textarea and then click the Convert button (with EBNF as target format) then click the View Diagram button to view a nice navigable railroad diagram.

I've just added this project grammar to https://mingodad.github.io/parsertl-playground/playground/ (select OctoSQL parser (partially working) under examples then click Parse to see the parser tree for the content of Input source editor).

The main repository is here https://github.com/mingodad/parsertl-playground it's a Yacc/Lex runtime grammar evaluator that can provide quick feedback loop when developing/testing/debug grammars.

It can also generate EBNF compatible with https://www.bottlecaps.de/rr/ui to generate railroad diagrams.

I hope it can help develop/debug/extend/test/document the grammar used in this project.

Any feedback is welcome !
