astronomia 0.3.2

Astronomical algorithms in Dart — positions of Sun, Moon, and planets, eclipses, phases, coordinates, magnitudes, and more. Based on Jean Meeus's "Astronomical Algorithms".

0.3.2

• Rename VSOP87 data files to lower_case_with_underscores (fixes 8 file_names lint issues).
• Remove unused imports and variables across test files.
• Fix unnecessary brace in string interpolation in sexagesimal.dart.
• Zero dart analyze issues.

0.3.1

• Add lib/<module>.dart public re-export files for all modules (fixes implementation_imports lint).
• Add missing lib/base.dart re-export, remove empty node directory.

0.3.0

• All 56 modules complete — no more stubs.
• Mars physical ephemeris — planetocentric declinations, areographic meridian, position angles, illuminated fraction (Ch. 42).
• Moon physical libration — optical + physical librations, selenographic Sun coordinates, sunrise/sunset on lunar surface, 52-feature catalog (Ch. 53).
• Saturn moons — positions of all 8 major moons (Mimas through Iapetus) in Saturn radii (Ch. 46).
• Planetary conjunctions — Len5 interpolation for planetary and stellar conjunctions (Ch. 18).
• Solar VSOP87 — added trueVSOP87() and apparentVSOP87() high-accuracy functions.
• Public re-export files — every module now has a lib/<module>.dart re-export. Import as package:astronomia/solar.dart instead of reaching into src/. No more implementation_imports lint.
• 216 tests passing.

0.2.0

• VSOP87 planetary positions — full heliocentric coordinates for all 8 planets via planetposition module.
• Rise/transit/set — Meeus ch. 15 refined algorithm with 3-day interpolation. Includes moonTimes() with lunar parallax correction.
• Geocentric planet positions — elliptic.position() with light-time correction, aberration, FK5, nutation.
• Equation of time — high-accuracy e() and simplified eSmart().
• Solar disk ephemeris — P, B0, L0 for physical observations of the Sun.
• Saturn ring geometry — B, B', ΔU, P, and ring axes.
• Ecliptic aberration — apparent.eclipticAberration() for ecliptic coordinates.
• Apparent sidereal time — sidereal.apparent0UT() with nutation correction.
• Cleaned up barrel file — non-conflicting foundational exports only, specialized modules imported directly.
• Fixed all lint warnings. 202 tests passing.

0.1.0

• Initial release with 45 fully ported modules from Meeus's "Astronomical Algorithms".
• Sun: position, solstices, sunrise/sunset, equation of time.
• Moon: position, phases, illumination, nodes, apsis, max declination.
• Planets: Kepler solvers, orbital elements, conjunctions, oppositions, Pluto.
• Coordinates: ecliptic/equatorial/horizontal/galactic, precession, nutation, parallax, refraction.
• Misc: eclipses, Easter, magnitudes, binary stars, geodesy, angular separation, sundials.
• 12 modules stubbed pending VSOP87 planetary theory data.
