This version includes: +* Replacement of `nlohmann::json` with `rapidjson` types (`Document`, `RValue`). +* A redesigned `minja::Value` class using `RValue rvalue_` for primitive JSON types and `std::unique_ptr owned_document_` for memory management when `minja::Value` owns the data (e.g., for strings or newly created JSON values). Minja-specific list (`ArrayType`) and map (`ObjectType`) are retained as shared pointers. +* Updated constructors for `minja::Value` to handle basic C++ types and initialize `rvalue_`. The constructor `Value(const nlohmann::json&)` is kept temporarily for bridging, converting `nlohmann::json` to the new `rapidjson`-based internal representation. +* A helper `get_rvalue_allocator()` in `minja::Value` to manage `owned_document_` and provide an allocator. +* Rewritten `dump()` and a new `dump_string_rvalue()` for string representation, catering to both Pythonic and JSON-style output. +* Updated type-checking methods (`is_string`, `is_number`, etc.) and other utility methods (`to_str`, `to_int`, `empty`, `size`, `keys`) to work with the `rvalue_` or the Minja-specific types. +* Revised operators (`+`, `-`, `*`, `/`, `%`, comparisons, `[]`) to handle operations between `minja::Value` instances, considering their underlying types (Minja map/array or `rvalue_`). The `at()` / `operator[]` for `rvalue_` JSON arrays/objects still has known challenges regarding returning references (`Value&`) safely. +* The `Parser`'s `parseNumber()` was replaced with `parseNumberRapid()` using `std::stoll/stod` to produce an `RValue`, and `parseConstant()` was updated accordingly. +* The `Context` class methods like `make` and `builtins` were adapted. `Context::builtins()` still has dependencies on the temporary `Value(const nlohmann::json&)` constructor for some complex filter arguments, which is a known area for future refinement (direct `RValue` to `minja::Value` construction). +* The `std::hash` specialization was updated. + +**Next Steps:** + +With `include/minja/minja.hpp` now (hopefully) in a state that reflects the `rapidjson` migration (albeit with some known areas needing refinement, especially around `Value::at()` and `RValue` to `minja::Value` conversion in `builtins`), I will proceed to refactor the remaining files. + +The next file is `examples/raw.cpp`.
