For instance, some models prepend a space like `' ' + message['content']` to ensure the first word can have a leading space, allowing the tokenizer to combine the word and space into a single token.

+ }); + parser.build_grammar(builder, data.grammar_lazy); +}); +``` + +The notable exception is the `negate(p)` lookahead parser, which cannot be +defined as a CFG grammar and therefore does not produce a rule. Its usage +should be limited and preferably hidden behind a `schema()` parser. In many +cases, `until(delimiter)` or `until_one_of(delimiters)` is a better choice. + +Another limitation is that the PEG parser requires an unambiguous grammar. In +contrast, the `llama-grammar` implementation can support ambiguous grammars, +though they are difficult to parse. + +### Lazy Grammars + +During lazy grammar generation, only rules reachable from a `trigger_rule(p)` +are emitted in the grammar. All trigger rules are added as alternations in the +root rule. It is still necessary to define trigger patterns, as the parser has +no interaction with the grammar sampling. + +### JSON Schema + +The `schema(p, name, schema, raw)` parser will use the `json-schema-to-grammar` +implementation to generate the grammar instead of the underlying parser. + +The `raw` option emits a grammar suitable for a raw string instead of a JSON +string. In other words, it won't be wrapped in quotes or require escaping +quotes. It should only be used when `type == "string"`. + +The downside is that it can potentially lead to ambiguous grammars. For +example, if a user provides the pattern `^.*$`, the following grammar may be +generated: + +``` +root ::= "" .* "" +``` + +This creates an ambiguous grammar that cannot be parsed by the PEG parser. To +help mitigate this, if `.*` is found in the pattern, the grammar from the +underlying parser will be emitted instead. + +## Common AST Shapes for Chat Parsing + +Most model output can be placed in one of the following categories: + +- Content only +- Tool calling with arguments emitted as a single JSON object +- Tool calling with arguments emitted as separate entities, either XML + (Qwen3-Coder, MiniMax M2) or pseudo-function calls (LFM2) + +To provide broad coverage, +[`common/chat-peg-parser.h`](common/chat-peg-parser.h) contains builders and +mappers that help create parsers and visitors/extractors for these types. They +require parsers to tag nodes to conform to an AST "shape". This normalization +makes it easy to extract information and generalize parsing. + +### Simple + +The `common_chat_peg_builder` builds a `simple` parser that supports +content-only models with optional reasoning. + +- **`reasoning(p)`** - Tag node for extracting `reasoning_content` +- **`content(p)`** - Tag node for extracting `content` + +```cpp +build_chat_peg_parser([&](common_chat_peg_parser & p) { + return p.sequence({ + p.optional("" + p.reasoning(p.until("")) + ""), + p.content(p.until("")), + p.end() + }); +}); +``` + +Use `common_chat_peg_mapper` to extract the content.
