T2 (`check_per_call_markers()`) disambiguates by checking if the second call in a two-call output starts with the section marker. +3. **Python Dict Format**: The Seed template family uses single-quoted JSON (`'key': 'value'`). The `uses_python_dicts` flag causes the PEG builder to register a flexible `json-string` rule accepting both quote styles before any JSON rules are built. +4. **Tag Boundary Fixing**: `calculate_diff_split()` iteratively adjusts prefix/suffix boundaries to avoid splitting `` or `[marker]` tokens, ensuring clean extraction. +5. **Call ID Side Effects**: When a call ID is detected, `per_call_end` may have been incorrectly set to include the call ID suffix. T7 clears `per_call_end` in this case. +6. **Tool Analysis Gating**: `analyze_tools` is only constructed (and all tool analysis phases run) when `jinja_caps.supports_tool_calls` is true. Within tool analysis, `check_per_call_markers()` (T2) only runs if `jinja_caps.supports_parallel_tool_calls`. +7. **`analyze_arguments()` Gating**: Within tool analysis, A1 and A2 (argument name/value marker extraction) only run for `TAG_WITH_TAGGED` format. `extract_argument_separator()` and `extract_args_markers()` run for all non-`JSON_NATIVE` formats. diff --git a/docs/development/parsing.md b/docs/development/parsing.md index 113ab2e2ee..d461b12f6b 100644 --- a/docs/development/parsing.md +++ b/docs/development/parsing.md @@ -22,7 +22,7 @@ Below is a contrived example demonstrating how to use the PEG parser to parse output from a model that emits arguments as JSON. ```cpp -auto parser = build_chat_peg_native_parser([&](common_chat_peg_native_builder & p) { +auto parser = build_chat_peg_parser([&](common_chat_peg_builder & p) { // Build a choice of all available tools auto tool_choice = p.choice();
