From 0d509f725fdbb24e0ff8e8b2f2df8fae16464282 Mon Sep 17 00:00:00 2001 From: Claude Date: Sat, 31 Jan 2026 17:48:04 +0000 Subject: [PATCH 01/15] Integrate VST3 validator directly into pluginval binary - Add VST3 SDK as a dependency via CPM (fetched during cmake configure) - Create VST3ValidatorRunner wrapper to call SDK validation APIs - Add --vst3-validator-mode CLI option for running embedded validator - Modify VST3validator test to use embedded validator instead of external binary - Remove --vst3validator CLI option and related UI code (no longer needed) - Update CLAUDE.md documentation with new build options and architecture The embedded validator eliminates the need for users to supply a separate vstvalidator binary path. When built with PLUGINVAL_VST3_VALIDATOR=ON (default), the validator runs automatically for VST3 plugins at strictness level 5+. https://claude.ai/code/session_01AY9chvBEmsCVjNZSUkNcbw --- CLAUDE.md | 26 ++ CMakeLists.txt | 41 +++ Source/CommandLine.cpp | 47 +++- Source/MainComponent.cpp | 42 --- Source/PluginTests.h | 1 - Source/tests/BasicTests.cpp | 29 ++- Source/vst3validator/VST3ValidatorRunner.cpp | 256 +++++++++++++++++++ Source/vst3validator/VST3ValidatorRunner.h | 48 ++++ 8 files changed, 429 insertions(+), 61 deletions(-) create mode 100644 Source/vst3validator/VST3ValidatorRunner.cpp create mode 100644 Source/vst3validator/VST3ValidatorRunner.h diff --git a/CLAUDE.md b/CLAUDE.md index beb407af..0f72a828 100644 --- a/CLAUDE.md +++ b/CLAUDE.md @@ -49,6 +49,9 @@ pluginval/ │ ├── PluginvalLookAndFeel.h # Custom UI styling │ ├── StrictnessInfoPopup.h # Strictness level info UI │ ├── binarydata/ # Binary resources (icons) +│ ├── vst3validator/ # Embedded VST3 validator integration +│ │ ├── VST3ValidatorRunner.h +│ │ └── VST3ValidatorRunner.cpp │ └── tests/ # Individual test implementations │ ├── BasicTests.cpp # Core plugin tests (info, state, audio) │ ├── BusTests.cpp # Audio bus configuration tests @@ -101,6 +104,7 @@ cmake --build Builds/Debug --config Debug | Option | Description | Default | |--------|-------------|---------| | `PLUGINVAL_FETCH_JUCE` | Fetch JUCE with pluginval | ON | +| `PLUGINVAL_VST3_VALIDATOR` | Build with embedded VST3 validator | ON | | `WITH_ADDRESS_SANITIZER` | Enable AddressSanitizer | OFF | | `WITH_THREAD_SANITIZER` | Enable ThreadSanitizer | OFF | | `VST2_SDK_DIR` | Path to VST2 SDK (env var) | - | @@ -177,6 +181,27 @@ struct Requirements { | `LocaleTest.cpp` | Locale handling verification | | `ExtremeTests.cpp` | Edge cases, stress tests | +### VST3 Validator Integration + +The VST3 validator (Steinberg's vstvalidator) is embedded directly into pluginval when built with `PLUGINVAL_VST3_VALIDATOR=ON` (the default).
