Source files that construct or manipulate JSON values must include `nlohmann/json.hpp` under `__JSON`. The existing CMake option `ENABLE_JSON` controls this feature. Callers using only the higher-level declarations in `init_info.h` or `output_info.h` do not need the backend header. -## Normal usage +## Constructing metadata -### Add/Modify a value to object json node (key2 is a object node): -```cpp -Json::AbacusJson::add_json({"key1","key2"}, 3.1415,false); -``` +`gen_general_info()` owns the whole `general_info` section and assigns it as a complete object: -### Pushback a value to array json node (key2 is a array node): ```cpp -Json::AbacusJson::add_json({"key1","key2"}, 3.1415,true); +AbacusJson::document()["general_info"] = { + {"version", version}, + {"commit", commit}, + {"device", param.inp.device}, + {"mpi_num", mpi_num}, + {"omp_num", omp_num}, + {"pseudo_dir", param.inp.pseudo_dir}, + {"orbital_dir", param.inp.orbital_dir}, + {"stru_file", param.globalv.global_in_stru}, + {"kpt_file", param.inp.kpoint_file}, + {"start_time", start_time_str}, + {"end_time", end_time_str}}; ``` -Through this function alone, the addition of the majority of JSON parameters can be achieved. However, for complex array types, additional operations are required. - - -## Initialization and Assignment Functions for Different Value Types in Arrays - -### Object Type: -Since the object type consists of key-value pairs, four member functions are divided based on whether key and val are of type std::string. - -- JaddStringV(str,val): key is not string, val is string -- JaddStringK(str,val): key is string, val is not string -- JaddStringKV(str,val): both key and val are string -- JaddNormal(str,val): both key and val are not string - - -### Array Type: -For array types, the following member functions are used directly. - -- JPushBack(val): val is not string -- JPushBackString(val): val is string - -For example, to add nodes to a JSON tree with multiple arrays in Abacus, the following code is needed: +The `init` section is shared by `gen_stru()`, `gen_init()`, and `add_nkstot()`. The first two construct the fields they own in a local object, then apply a **shallow** update: ```cpp -// add key-val to an object array -for(int i=0;i<1;i++){ - Json::jsonValue object(JobjectType); - std::string str = std::to_string(i*100); - - object.JaddNormal("int",i); - object.JaddStringV("string", str); - Json::AbacusJson::add_json({"array"}, object,true); -} +// Inside init_info.cpp; init_section() is local to this source file. +init_section().update(info); ``` -```cpp -// add array in array -Json::jsonValue object0(JarrayType); +The local helper creates a missing `init` object but rejects an existing non-object, including `null`. The update preserves fields supplied by the other generators and replaces each supplied value as a whole. In particular, per-species maps and coordinate arrays must not retain stale entries or accumulate on repeated generation. Do not assign a newly generated object to the entire `init` section, and do not enable recursive object merging here. -object0.JPushBack(1); -object0.JPushBack(2); -object0.JPushBack(3); +`add_nkstot()` only sets its own field: -Json::AbacusJson::add_json({"Darray"}, object0,true); +```cpp +init_section()["nkstot"] = nkstot; ``` +## Output-record lifecycle +The workflow starts each record with `init_output_array_obj()` **before** the corresponding solver writes SCF or other result data. That function alone creates the `output` array and appends the initial record. It rejects an existing `output` value that is not an array; an explicit `null` is not treated as a missing field. +The existing workflow entry points own this initialization: +| Workflow | Record initialization | +| --- | --- | +| SCF/relaxation | `Relax_Driver::iter_info()` starts the record, except for the first `ks-lr` step described below. | +| `ks-lr` | `ESolver_LR::before_all_runners()` starts the record before its embedded KS calculation; the first relaxation-driver step reuses it. | +| UnitCell-backed MD | `Run_MD::md_line()` starts a record at the beginning of each MD iteration when `mdcell.has_backing_unitcell()` is true. | +| Socket/i-PI | `SocketHandlers::handle_posdata()` starts a record before running the solver for the received `POSDATA` frame. | -## Array Modification Instructions +Do not move record creation into individual field writers, create a second record for the same step, or reset the whole document to start a new step. -For values that need to be modified in arrays, the following method can be used: -- The index number of the array starts at 0, if it's negative, it's going from back to front. eg. If the index is -1, it means that the last element of the array is modified: -- If the path contains an array, use the array index directly. +The result writers use `current_output()`, a helper local to `output_info.cpp`. It rejects a missing or non-array `output`, an empty array, or a final element that is not an object. It never creates a record as a side effect of writing a result. -```cpp -AbacusJson::add_json({"path",index }, value, is_array); -``` +For example, inside namespace `Json` in `output_info.cpp`: -Here, index is a number. index >= 0 indicates the index from the beginning of the array, while index < 0 indicates traversal from the end of the array. - -For example, to modify the value of "vasp" to "cp2k" in the following JSON tree: - -```json -"Json":{ - "key6": { - "key7": [ - { - "a":1, - "new":2 - } - "vasp", - "abacus" - ] - } +```cpp +void add_output_energy(const double energy) +{ + current_output()["energy"] = energy; } ``` -The relative path of "vasp" in layman's terms is Json - key6 - key7[0]. To use the JSON modification method in abacus, simply change the index [0] to "0". -```cpp -AbacusJson::add_json({"Json","key6","key7",1}, "cp2k" , false); -``` +Coordinate, force, stress, magnetic-moment, and cell arrays are built locally and assigned as complete arrays. Repeatedly updating the same record must replace these arrays rather than append rows. -If traversal is done from the end: -```cpp -AbacusJson::add_json({"Json","key6","key7",-2}, "cp2k", false); -``` +SCF iterations are different: they form a history and must be appended. `add_output_scf_mag()` creates a missing `scf` array, rejects an existing non-array history, and appends one iteration object. Its implementation uses: -An error is reported if index exceeds the array length! ```cpp -AbacusJson::add_json({"Json","key6","key7",3}, "cp2k", false); +jsonValue& output = current_output(); +output["total_mag"] = total_mag; +output["absolute_mag"] = absolute_mag; +jsonValue& scf = *output.emplace("scf", jsonValue::array()).first; +if (!scf.is_array()) +{ + throw std::invalid_argument("JSON SCF history must be an array"); +} +scf.push_back({{"energy", energy}, {"ediff", ediff}, + {"drho", drho}, {"time", time}}); ``` +`ordered_json` may invalidate references to child values when new members are inserted into their parent object. Acquire the `scf` reference after inserting `total_mag` and `absolute_mag`, and do not retain a record reference across appending another `output` record. The same caution applies to references to root sections when new root keys are inserted. +## Serialization and tests +`document()` and `write_to_json()` do not perform MPI rank filtering. The existing `json_output()` wrapper writes `abacus.json` only on rank 0 in MPI builds; callers outside `module_json` should retain the existing integration wrappers. -# 2. Abacus Json Codes Addition Guidelines - -## Abacus JSON Functionality Code Structure +`write_to_json()` preserves the existing four-space formatting and reports file-open and write/close failures. It serializes the document before opening the destination, so a serialization error does not first truncate the file. Non-finite numbers serialize as JSON `null`; decimal versus scientific float notation is not part of the schema contract. -The current code structure of JSON functionality in Abacus is roughly as follows: +The tests reset the shared document through `document()` in their fixture; no access-control macro or friend accessor is needed. Focus coverage on ABACUS behavior: generated fields and units, repeated metadata updates, record initialization and SCF accumulation, invalid section types, insertion order, escaping and non-finite values through the real writer, and file errors.

Whenever possible, code to be added in the module should be written in the `json_output` module (there may also be cases where parameters cannot be directly obtained through parameter passing in `json_output`), and then called in the path `para_json.cpp` -> `device.cpp` or other main execution paths. (Ensure minimal impact on other modules as much as possible) - -2. For parameters that can be obtained without depending on other modules, do not reference parameter values saved in other modules. (Such as `mpi_num`, `start_time`) - -3. Use classes as function parameters as much as possible instead of using global classes for obtained parameters. (For example, in `gen_general_info`, `Input`) +`init_section()` and `current_output()` are file-local helpers, not public interfaces for workflow callers. -4. After adding parameters, supplement test code in `source_io/json_output/test`. +## Guidelines for extending JSON output -For the current JSON file, there are two JSON modules: `init` and `general_info`, `output_info`. -Taking `general_info` as an example, the code to be added is as follows: +Keep construction in the existing schema generator, pass its required data explicitly, and avoid adding `GlobalV`, `GlobalC`, or `PARAM` access. Preserve field names, value types, units, and order unless a schema change is intentional. Add focused tests for new fields and lifecycle behavior, and update the [JSON output reference](json_para.md) when the public schema changes. -```cpp -namespace Json -{ - -#ifdef __RAPIDJSON -void gen_general_info(const Parameter& param) -{ - -#ifdef VERSION - const std::string version = VERSION; -#else - const std::string version = "unknown"; -#endif -#ifdef COMMIT - const std::string commit = COMMIT; -#else - const std::string commit = "unknown"; -#endif - - // start_time - std::time_t start_time = input->get_start_time(); - std::string start_time_str; - convert_time(start_time, start_time_str); - - // end_time - std::time_t time_now = std::time(NULL); - std::string end_time_str; - convert_time(time_now, end_time_str); - -#ifdef __MPI - int mpi_num = Parallel_Global::mpi_number; - int omp_num = Parallel_Global::omp_number; -#elif - int mpi_num = 1; - int omp_num = 1; -#endif - - AbacusJson::add_json({"general_info", "version"}, version,false); - AbacusJson::add_json({"general_info", "commit"}, commit,false); - AbacusJson::add_json({"general_info", "device"}, input->device,false); - AbacusJson::add_json({"general_info", "mpi_num"}, mpi_num,false); - AbacusJson::add_json({"general_info", "omp_num"}, omp_num,false); - AbacusJson::add_json({"general_info", "pseudo_dir"}, input->pseudo_dir,false); - AbacusJson::add_json({"general_info", "orbital_dir"}, input->orbital_dir,false); - AbacusJson::add_json({"general_info", "stru_file"}, input->stru_file,false); - AbacusJson::add_json({"general_info", "kpt_file"}, input->kpoint_file,false); - AbacusJson::add_json({"general_info", "start_time"}, start_time_str,false); - AbacusJson::add_json({"general_info", "end_time"}, end_time_str,false); -} -#endif -} // namespace Json -``` \ No newline at end of file +Keep examples and new implementation code compatible with the C++11 baseline.
