LALR(1) parser generator for Rust based on Lemon + SQL parser
The following input crashes the parser because of an invalid UTF8 sequence [bad-utf8.txt](https://github.com/gwenn/lemon-rs/files/14605850/bad-utf8.txt)

(a) from official test suite, we need to have both DDL and statement. (b) introduce `rusqlite` as a test dependency ? (c) check `Cmd#column_count` vs `sqlite3_column_count` (d) check `Cmd#readonly` vs...
Sqite has a rather flexible syntax for joins, and the parser should support them. This PR alleviate the restriction on joins, and make them more flexible. see: https://www.sqlite.org/lang_select.html#strange_join_names
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...
I am wondering how hard it would be to have spanned AST node. It would be very useful to retrieve the subslice of the original string that an AST node...
```sh % rg -FN 'sqlite3ErrorMsg(pParse, "' sqlite3.c ``` ```C sqlite3ErrorMsg(pParse, "misuse of aliased aggregate %s", zAs); sqlite3ErrorMsg(pParse, "misuse of aliased window function %s",zAs); sqlite3ErrorMsg(pParse, "row value misused"); sqlite3ErrorMsg(pParse, "%s: %s.%s.%s",...
