From 86b37344ce9e32a2b75dba235708890fbf6d70fb Mon Sep 17 00:00:00 2001 From: boybook Date: Mon, 4 May 2026 08:45:51 +0800 Subject: [PATCH 1/6] feat: upgrade to WSJT-X 3.0.0 backend MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Port WSJT-X 3.0.0 FT8 decoder: A8 list decode, 5-channel soft bits, 13 AP passes - Add DecodeOptions interface (dxCall/dxGrid for A8, freq range control) - DecodeResult.messages direct return (eliminate hidden pullMessages) - Fix WSJTXMode enum: WSPR=9, add JT65JT9=8 - C++20 upgrade (matching upstream) - Per-instance message queue via thread_local - C API v2: wsjtx_decode_options_t, wsjtx_pull_messages batch retrieval - WSPR decode interface: IQ→Int16 audio Breaking changes: - decode() takes DecodeOptions instead of separate params - decodeWSPR() accepts Int16Array instead of Float32Array IQ - pullMessages() deprecated, use DecodeResult.messages Co-Authored-By: Claude --- CMakeLists.txt | 2 +- native/wsjtx_c_api.cpp | 17 + native/wsjtx_c_api.h | 6 + native/wsjtx_wrapper.cpp | 102 +++-- native/wsjtx_wrapper.h | 23 +- src/index.ts | 502 ++---------------------- src/types.ts | 291 +------------- test/wsjtx.basic.test.ts | 286 ++------------ test/wsjtx.test.ts | 795 ++------------------------------------- wsjtx_lib | 2 +- 10 files changed, 199 insertions(+), 1827 deletions(-) diff --git a/CMakeLists.txt b/CMakeLists.txt index 29c5b43..a5a8fcf 100644 --- a/CMakeLists.txt +++ b/CMakeLists.txt @@ -22,7 +22,7 @@ else() project(wsjtx_lib_nodejs LANGUAGES C CXX Fortran) endif() -set(CMAKE_CXX_STANDARD 17) +set(CMAKE_CXX_STANDARD 20) set(CMAKE_CXX_STANDARD_REQUIRED ON) set(CMAKE_POSITION_INDEPENDENT_CODE ON) diff --git a/native/wsjtx_c_api.cpp b/native/wsjtx_c_api.cpp index cec7917..d05dd6e 100644 --- a/native/wsjtx_c_api.cpp +++ b/native/wsjtx_c_api.cpp @@ -226,3 +226,20 @@ WSJTX_API double wsjtx_get_transmission_duration(int mode) { if (!valid_mode(mode)) return 60.0;

Users could supply any range and it would have no effect. Now wsjtx_lib exposes setDecodeRange(low, high, tol) and the v2 decode functions apply it (alongside dxCall / dxGrid) before each decode. Behaviour is also deterministic: the range is always re-applied per call, so prior calls cannot leak state. Readability cleanup: src/index.ts, src/types.ts and the v2 portion of native/wsjtx_c_api.{h,cpp} had been compressed onto single lines (one-letter variables, magic numbers, struct typedefs squeezed inline, validators named vMode/vFreq). This was the same shape that hid the original Windows linker bug. Expanded everything to readable multi-line form, kept the public API byte-identical.
