Opt in with either: exp2cxx --api-version 2 schema.exp or: cmake -DSC_EXP2CXX_API_VERSION=2 ... Version 1 remains the default, and the regression test verifies default output is byte-identical to explicit v1 output. API v2 now provides: - Compact SELECT classes backed by shared descriptor-driven runtime code instead of repeated generated parsing, assignment, and serialization bodies. - Generic Set* and typed getter APIs in include/clstepcore/sdaiSelect.h:109. - Dependency-bounded entity headers and source-owned dependencies in src/exp2cxx/classes_entity.c:968. - Out-of-line entity creators. - Unity chunks that no longer include the all-entity header. - C++11 output; C++17 did not offer enough additional benefit for this tranche. The command-line handling is in src/exp2cxx/fedex_main.c:85, while compact SELECT generation begins in src/exp2cxx/selects.c:702. Measured using the BRL-CAD ap242e4.exp, Release builds, eight parallel jobs, and 64:8 unity chunks: Metric API v1 Final API v2 Reduction ━━━━━━━━━━━━━━━━━━━━━━━━ ━━━━━━━━━━━━━━━ ━━━━━━━━━━━━━━ ━━━━━━━━━━━ Generated C++ lines 1,210,640 522,445 56.8% ──────────────────────── ─────────────── ────────────── ─────────── Generated bytes 57,566,051 27,202,644 52.7% ──────────────────────── ─────────────── ────────────── ─────────── Schema build wall time 183.22 s 88.31 s 51.8% ──────────────────────── ─────────────── ────────────── ─────────── Compiler CPU time 641.53 s 378.49 s 41.0% ──────────────────────── ─────────────── ────────────── ─────────── Peak RSS 1,035,112 KiB 916,412 KiB 11.5% ──────────────────────── ─────────────── ────────────── ─────────── Object-file bytes 70,472,952 40,031,088 43.2% ──────────────────────── ─────────────── ────────────── ─────────── Shared-library text 34,361,400 19,420,467 43.5% ──────────────────────── ─────────────── ────────────── ─────────── Generation wall time 1.52 s 0.69 s 54.6%
