name: validate description: Validate iPlug2 plugin builds using format-specific validators (auval, pluginval, vstvalidator, clap-validator) (project)

Validate iPlug2 Plugin

Validate a built plugin using format-specific validation tools. Plugin must have been built prior to using this skill.

Arguments

PROJECT_NAME (required): Name of the project (e.g., IPlugEffect)
FORMAT (optional): Specific format to validate (AU, AUv3, VST3, CLAP, all). Default: all

Validation Workflow

Step 1: Read config.h to extract plugin identifiers

Read Examples/[PROJECT_NAME]/config.h or Tests/[PROJECT_NAME]/config.h and extract:

PLUG_NAME - Plugin display name
PLUG_UNIQUE_ID - 4-char subtype (e.g., 'Ipef' → Ipef)
PLUG_MFR_ID - 4-char manufacturer code (e.g., 'Acme' → Acme)
PLUG_MFR - Manufacturer display name
PLUG_TYPE - 0=effect (aufx), 1=instrument (aumu), 2=MIDI effect (aumf)

Step 2: Determine AU type from PLUG_TYPE

PLUG_TYPE 0 → aufx
PLUG_TYPE 1 → aumu
PLUG_TYPE 2 → aumf

Step 3: Validate each format

AUv2 (macOS) - auval

# Restart audio server first to pick up changes
sudo killall -9 AudioComponentRegistrar 2>/dev/null; sleep 1

# Run validation
auval -v [AU_TYPE] [PLUG_UNIQUE_ID] [PLUG_MFR_ID]

Example: auval -v aufx Ipef Acme

Look for AU VALIDATION SUCCEEDED at the end.

Useful auval options:

-strict - Enforce strict checks (recommended for release)
-r N - Repeat validation N times
-o - Quick open/init test only (faster debugging)
-q - Quiet mode (errors/warnings only)

AUv3 (macOS) - auval

Note: The host app must be built codesigned and launched at least once to register the AUv3 extension. AUv2 plugin should be removed to avoid conflict. Auval usage the same as AUv2, but should see "This AudioUnit is a version 3 implementation."

VST3 - vstvalidator

Build vstvalidator if not present:

# macOS/Linux
cd Dependencies/IPlug && ./download-vst3-sdk.sh master build-validator

# Windows (use Git Bash or WSL)
cd Dependencies/IPlug && ./download-vst3-sdk.sh master build-validator

The validator binary will be at Dependencies/IPlug/VST3_SDK/validator (or validator.exe on Windows).

Run validation:

# macOS
Dependencies/IPlug/VST3_SDK/validator ~/Library/Audio/Plug-Ins/VST3/[PLUG_NAME].vst3

# Windows
Dependencies\IPlug\VST3_SDK\validator.exe "C:\Program Files\Common Files\VST3\[PLUG_NAME].vst3"

CLAP - clap-validator

Install clap-validator: Download from https://github.com/free-audio/clap-validator/releases

Run validation:

# macOS
clap-validator validate ~/Library/Audio/Plug-Ins/CLAP/[PLUG_NAME].clap

# Windows
clap-validator.exe validate "C:\Program Files\Common Files\CLAP\[PLUG_NAME].clap"

Look for X tests run, Y passed, 0 failed at the end.

Useful options:

--in-process - Run in-process (faster)
--only-failed - Show only failed tests

Multi-format: pluginval

# macOS
brew install --cask pluginval
/Applications/pluginval.app/Contents/MacOS/pluginval --strictness-level 5 --validate ~/Library/Audio/Plug-Ins/VST3/[PLUG_NAME].vst3

# Windows (download from https://github.com/Tracktion/pluginval/releases)
pluginval.exe --strictness-level 5 --validate "C:\Program Files\Common Files\VST3\[PLUG_NAME].vst3"

Plugin Locations

Format	macOS	Windows
AUv2	`~/Library/Audio/Plug-Ins/Components/[NAME].component`	N/A
AUv3	`~/Applications/[NAME].app/Contents/PlugIns/[NAME].appex`	N/A
VST3	`~/Library/Audio/Plug-Ins/VST3/[NAME].vst3`	`C:\Program Files\Common Files\VST3\[NAME].vst3`
CLAP	`~/Library/Audio/Plug-Ins/CLAP/[NAME].clap`	`C:\Program Files\Common Files\CLAP\[NAME].clap`

Expected Output

Report validation results in a table:

Format	Status	Details
AUv2	PASS/FAIL	Brief summary
AUv3	PASS/FAIL/SKIP	Reason if skipped
VST3	PASS/FAIL/SKIP	Reason if skipped
CLAP	PASS/FAIL/SKIP	Reason if skipped
