common : implement new jinja template engine (#18462)
* jinja vm * lexer * add vm types * demo * clean up * parser ok * binary_expression::execute * shadow naming * bin ops works! * fix map object * add string builtins * add more builtins * wip * use mk_val * eval with is_user_input * render gemma tmpl ok * track input string even after transformations * support binded functions * keyword arguments and slicing array * use shared_ptr for values * add mk_stmt * allow print source on exception * fix negate test * testing more templates * mostly works * add filter_statement * allow func to access ctx * add jinja-value.cpp * impl global_from_json * a lot of fixes * more tests * more fix, more tests * more fixes * rm workarounds * demo: type inferrence * add placeholder for tojson * improve function args handling * rm type inference * no more std::regex * trailing spaces * make testing more flexible * make output a bit cleaner * (wip) redirect minja calls * test: add --output * fix crash on macro kwargs * add minimal caps system * add some workarounds * rm caps_apply_workarounds * get rid of preprocessing * more fixes * fix test-chat-template * move test-chat-jinja into test-chat-template * rm test-chat-jinja from cmake * test-chat-template: use common * fix build * fix build (2) * rename vm --> interpreter * improve error reporting * correct lstrip behavior * add tojson * more fixes * disable tests for COMMON_CHAT_FORMAT_GENERIC * make sure tojson output correct order * add object.length * fully functional selectattr / rejectattr * improve error reporting * more builtins added, more fixes * create jinja rendering tests * fix testing.h path * adjust whitespace rules * more fixes * temporary disable test for ibm-granite * r/lstrip behavior matched with hf.js * minimax, glm4.5 ok * add append and pop * kimi-k2 ok * test-chat passed * fix lstrip_block * add more jinja tests * cast to unsigned char * allow dict key to be numeric * nemotron: rm windows newline * tests ok * fix test * rename interpreter --> runtime * fix build * add more checks * bring back generic format support * fix Apertus * [json.exception.out_of_range.403] key 'content' not found * rm generic test * refactor input marking * add docs * fix windows build * clarify error message * improved tests * split/rsplit with maxsplit * non-inverse maxsplit forgot to change after simplifying * implement separators for tojson and fix indent * i like to move it move it * rename null -- > none * token::eof * some nits + comments * add exception classes for lexer and parser * null -> none * rename global -> env * rm minja * update docs * docs: add input marking caveats * imlement missing jinja-tests functions * oops * support trim filter with args, remove bogus to_json reference * numerous argument fixes * updated tests * implement optional strip chars parameter * use new chars parameter * float filter also has default * always leave at least one decimal in float string * jinja : static analysis + header cleanup + minor fixes * add fuzz test * add string.cpp * fix chat_template_kwargs * nits * fix build * revert * unrevert sorry :) * add fuzz func_args, refactor to be safer * fix array.map() * loosen ensure_vals max count condition, add not impl for map(int) * hopefully fix windows * check if empty first * normalize newlines --------- Co-authored-by: Alde Rojas <hello@alde.dev> Co-authored-by: Sigbjørn Skjæret <sigbjorn.skjaeret@scala.com> Co-authored-by: Georgi Gerganov <ggerganov@gmail.com>
