- Rewrite precalc_moon_orbits.py to output orbit params as dotted keys
(orbit.semi_major_axis = ...) instead of nested tables, conforming
to TOML 1.0 spec for Python compatibility
- Add print_cpp_expected_values() helper to script output
- Add new test_moon_orbits.cpp replacing old_tests version:
* MoonData struct now carries int parent_index instead of pointer
* Eliminate opaque pointer arithmetic for parent index comparison
* Collect failures in vector during sim loops, assert once at end
(reduces assertions from 763,230 to 43 per test)
- Add test_moon_orbits.toml generated from precalc script
- Move all configs from tests/configs/ to tests/
- Rename configs to match test filenames (test_NAME.toml)
- Remove unused configs (earth_mars_simple, simple_root_transition, interplanetary_transfer)
- Combine earth_circular and mars_circular into test_orbital_period.toml
- Duplicate earth_circular.toml as test_energy.toml
- Remove invalid parent test case from test_invalid_parent_assignment.cpp
- Update all test files to reference new config paths
- Delete tests/configs/ directory
- Fixed velocity calculation in compute_orbital_velocity_from_vis_viva to use semi_major_axis for circular orbits instead of computing distance from global coordinates
- Fixed Titan's initial position in solar_system.toml to match semi_major_axis (1.43522e12 instead of 1.435e12)
- Moon orbit tests now pass (238,759 assertions)
- Created tests/test_moon_orbits.cpp with 4 test cases:
* Moon orbital stability around Earth
* Galilean moons orbital stability around Jupiter
* Titan orbital stability around Saturn
* Combined solar system parent stability
- Enhanced test_utilities.h/cpp:
* Added min_time_days field to OrbitTracker
* Added create_orbit_tracker_with_min_time() for short-period orbits
- Fixed parent indexes in tests/configs/solar_system.toml:
* Moon: parent 3 (Mars) → 2 (Earth)
* Io/Europa/Ganymede/Callisto: parent 5 (Saturn) → 4 (Jupiter)
* Titan: parent 6 (Uranus) → 5 (Saturn)
- Updated semi_major_axis for moons to actual orbital distances
Tests reveal need for hierarchical orbit physics implementation.
Net change: +368 lines
- Add tomlc17 library as git submodule
- Update Makefile to build tomlc17.c with C compiler
- Replace config_loader.cpp with TOML-based implementation
- Add helper functions for parsing TOML tables (position, color)
- Convert all 5 config files from .txt to .toml format:
* configs/solar_system.toml - full solar system with planets and moons
* configs/example_binary_star.toml - binary star system
* configs/test_simple.toml - various orbit types for testing
* tests/configs/earth_circular.toml - Earth orbit test
* tests/configs/mars_circular.toml - Mars orbit test
- Update all test files to reference .toml extensions
- Remove old .txt config files (maintain compatibility)
- Support both INT64 and FP64 TOML values (tomlc17 type flexibility)
- All automated tests pass with new TOML format
