This package wraps the project-owned `jme_*` C API from the JPL Moshier Ephemeris native library. Contract -------- [](#contract) - Primary public functions: `jme_*` - Primary public constants: `JME_*` - Current wrapper target: all 204 public `jme_*` functions tracked by the native API inventory - Native headers contain 462 `JME_*` tokens including two header guards; the PHP wrapper exposes the semantic native constants and preserves existing compatibility aliases where present - Native backend: `libjme.so`, `libjme.dylib`, or `jme.dll` - No hidden rounding, output reshaping, or dropped status/error buffers - Incomplete native behavior should return `JME_ERR` from the C library rather than pretending to provide production ephemeris output Engine Selection ---------------- [](#engine-selection) The low-level `JmeEphFFI` class exposes every native function directly. The optional Laravel-style `JmeService::calc()` convenience method sets `ENGINE=...` through `jme_set_astro_models()` and then calls `jme_calc()`: - `AUTO`: let the native C core choose its standard JPL/fallback policy - `JPL`: require JPL kernel-backed behavior - `MOSHIER`: force Moshier analytical behavior - `VSOP_ELP_MEEUS`: force VSOP87/ELP2000/Meeus analytical behavior Use direct `jme_jpl_*` calls for raw JPL/CALCEPH kernel access. The PHP layer does not normalize or reinterpret native outputs. Requirements ------------ [](#requirements) - PHP `^8.3` - PHP FFI extension (`ext-ffi`) - A compiled JME shared library - The matching CALCEPH runtime library when using the JPL/CALCEPH backend By default, the wrapper loads the bundled platform library from this package, for example: ``` vendor/jayeshmepani/jpl-moshier-ephemeris-php/libs/linux-x64/libjme.so ``` Override it with: ``` export JME_LIBRARY_PATH=/path/to/libjme.so ``` Runtime Libraries and Kernels ----------------------------- [](#runtime-libraries-and-kernels) Composer installs prebuilt runtime archives from this repository's GitHub releases when a local library is not already present. Each runtime archive contains: - JME: `jme.dll`, `libjme.so`, or `libjme.dylib` - CALCEPH: the platform runtime library required by JPL kernel mode JPL `.bsp` kernels are not shipped in this package. Download them separately from the native JME kernel release: ``` https://github.com/jayeshmepani/jpl-ephemeris/releases/tag/jpl-kernels ``` Supported kernel choices: - `de440s.bsp` - small - `de440.bsp` - medium - `de441.bsp` - large, published as split release parts because the full file exceeds GitHub's single asset size limit Quick Start ----------- [](#quick-start) ``` use FFI; use JmeEph\FFI\JmeEphFFI; $jme = new JmeEphFFI(); $jd = $jme->jme_julian_day( 2000, 1, 1, 12.0, JmeEphFFI::JME_CALENDAR_GREGORIAN ); $xx = $jme->getFFI()->new('double[6]'); $error = $jme->getFFI()->new('char[256]'); $result = $jme->jme_calc_ut( $jd, JmeEphFFI::JME_BODY_SUN, JmeEphFFI::JME_CALC_NONE, $xx, $error ); if ($result === JmeEphFFI::JME_OK) { echo "Sun longitude: {$xx[0]}\n"; } else { echo 'JME error: ' . FFI::string($error) . "\n"; } ``` Test ---- [](#test) ``` composer install composer verify:surface composer test ``` The test suite verifies the PHP wrapper against the JME-native contract, including function inventory coverage, constant inventory coverage, key `JME_*` values, and convenience calculation paths. Set `JME_SOURCE_PATH` if the native source tree is not at the default local path. `composer verify:surface` performs an exact low-level surface audit of the generated wrapper: - `204` tracked `jme_*` declarations compared against the native header prototypes - `462` `JME_*` constants compared against native header values - numeric constants cross-checked through a compiled C probe instead of trusting PHP generation alone ### Health Score 41 — FairBetter than 87% of packages Maintenance88 Actively maintained with recent releases Popularity8 Limited adoption so far Community12 Small or concentrated contributor base Maturity50 Maturing project, gaining track record Bus Factor1 Top contributor holds 77.5% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
