grammars: x{min,max} repetition operator (#6640)
* grammars: x{min,max} repetition operator + tweak +/*/? to avoid duplication of original over alternates * grammars: handle `x{n}` and fix `x{n,n}` * grammars: document new repetition operators * grammars: uniform use of int for min & max * grammars: refactor parser test * grammar: parsing tests w/ natural pretty print of updated expectations * grammars: much prettier print of expectations (+ TEST_GRAMMAR_PARSER_PRINT_ALL=1 to force all) * grammars: improve test pretty print again * grammars: pretty print rules and chars * grammars: fix copy rule skipping * grammars: disallow `a{,}` (not allowed in regexps) * Update common/grammar-parser.cpp Co-authored-by: Clint Herron <hanclinto@gmail.com> * grammars: fix copy rule skipping (again) & display of expectations * grammars: more test cases * grammars: update reps parsing to bring ? / * / + closer to before * json: use new GBNF repetitions{m,n} syntax * grammars: update performance gotchas w/ repetition advice * Update examples/json_schema_to_grammar.py Co-authored-by: Clint Herron <hanclinto@gmail.com> * Update examples/server/public/json-schema-to-grammar.mjs Co-authored-by: Clint Herron <hanclinto@gmail.com> * grammars: comment on rule repetitions * grammars: ensure unambiguous number alternatives * grammar: nit typo switched error msgs * grammar: nit numbering in comment * json: update numeric rule to be unambiguous * Apply suggestions from code review Co-authored-by: Clint Herron <hanclinto@gmail.com> * Update examples/server/public/json-schema-to-grammar.mjs Co-authored-by: Clint Herron <hanclinto@gmail.com> * json: fix integral-part * grammar: add repetition tests --------- Co-authored-by: Clint Herron <hanclinto@gmail.com>
