LALR(1)/Lex online editor/tester for grammars

[mingodad]

I've just added this project grammar on https://mingodad.github.io/parsertl-playground/playground/ that is an editor/tester for yacc/lex grammars, select TDengine SQL parser from Examples then click Parse to see the parser tree of the sql in Input source.

I hope it'll help document/debug/develop/test the grammar .

For it to work on the online playground I needed to add NK_SEMI that was not defined/used in the grammar and add 2 new rules to allow parse multiple statements.

%start commands

%%

commands :
    command
    | commands command
    ;

command :
    NK_SEMI
    | cmd
    ;

Any feedback is welcome !
