# FastLED CI/Build System Agent Guidelines
## 🔧 Python Build System
### Core Architecture
FastLED uses a high-performance Python-based build system:
**Key Components:**
- `ci/compiler/clang_compiler.py` - Core compiler with PCH and fingerprint cache
- `ci/ci/fingerprint_cache.py` - 99% faster PCH rebuilds through intelligent caching
- `ci/util/build_flags.py` - TOML-based build configuration management
- `ci/compiler/test_example_compilation.py` - Example compilation system
**Performance Features:**
- **PCH (Precompiled Headers)** - Dramatically faster compilation
- **Fingerprint Cache** - 99% time reduction for unchanged dependencies
- **Parallel Compilation** - Automatic CPU-optimized parallel builds
- **Smart Rebuilds** - Only rebuild when source files actually change
### 🚨 Command Execution Rules
#### FOREGROUND AGENTS (Interactive Development)
**Python Code Execution:**
- ✅ **Create/modify tmp.py** in project root (NOT subdirectories)
- ✅ **Always run: `uv run python tmp.py`** (never just `python`)
- ✅ **Correct import paths:** `from ci.ci.module` for ci.ci modules, `from ci.module` for top-level ci modules
- ❌ **NEVER cd to subdirectories** - stay in project root
**Example:**
```python
# tmp.py (created in project root)
from ci.ci.clang_compiler import Compiler # CORRECT import path
import subprocess
result = subprocess.run(['git', 'status'], capture_output=True, text=True)
print(result.stdout)
```
Then run: `uv run python tmp.py`
#### BACKGROUND AGENTS (Automated/CI Environments)
**Restrictions:**
- ❌ **NO tmp.py files** (forbidden for background agents)
- ✅ **Use existing scripts:** `uv run python ci/ci-compile.py uno --examples Blink`
- ✅ **Use MCP server tools** for programmatic operations
- ✅ **Always use `uv run python`** with existing scripts
## 🤖 MCP Server Configuration
**Start server:** `uv run mcp_server.py`
**Available Tools:**
- Running tests with various options
- Compiling examples for different platforms
- Code fingerprinting and change detection
- Linting and formatting
- **Build info analysis** for platform-specific defines, compiler flags, toolchain information
- **Symbol analysis** for binary optimization (all platforms)
- Stack trace setup for enhanced debugging
- **🌐 FastLED Web Compiler** with Playwright (FOREGROUND AGENTS ONLY)
- **🚨 `validate_completion` tool** (MANDATORY for background agents)
### FastLED Web Compiler (FOREGROUND AGENTS ONLY)
**Prerequisites:**
- `pip install fastled` - FastLED web compiler
- `pip install playwright` - Browser automation
- Docker (optional, for faster compilation)
**Usage via MCP Server:**
```python
# Basic usage
use run_fastled_web_compiler tool with:
- example_path: "examples/Audio"
- capture_duration: 30
- headless: false
- save_screenshot: true
```
**Key Features:**
- Compiles Arduino sketches to WASM for browser execution
- Captures console.log output with playwright automation
- Takes screenshots of running visualizations
- Monitors FastLED_onFrame calls to verify proper initialization
**🚫 BACKGROUND AGENT RESTRICTION:** This tool is COMPLETELY DISABLED for background agents and CI environments.
## 🤖 Linting Guidelines
### FOREGROUND AGENTS
**🚨 ALWAYS USE `bash lint` - DO NOT RUN INDIVIDUAL LINTING SCRIPTS**
- ✅ **CORRECT:** `bash lint`
- ❌ **FORBIDDEN:** `./lint-js`, `./check-js`, `python3 scripts/enhance-js-typing.py`
- ❌ **FORBIDDEN:** `uv run ruff check`, `uv run black`, individual tools
**WHY:** `bash lint` provides comprehensive coverage of Python, C++, JavaScript, and enhancement analysis.
### BACKGROUND AGENTS
**CAN USE FINE-GRAINED LINTING FOR SPECIFIC NEEDS**
Background agents may use individual linting scripts when needed:
- `./lint-js` - JavaScript-only linting
- `./check-js` - JavaScript type checking
- `python3 scripts/enhance-js-typing.py` - JavaScript enhancement analysis
- `uv run ruff check` - Python linting only
- MCP server `lint_code` tool - Programmatic access
**BUT STILL PREFER `bash lint` FOR COMPREHENSIVE CHECKING**
## Build System Commands
**Unit Test Compilation:**
```bash
# Fast Python API (default)
bash test --unit --verbose # Uses PCH optimization
# Disable PCH if needed
bash test --unit --no-pch --verbose
# Legacy CMake system (8x slower)
bash test --unit --legacy --verbose
```
**Available Build Options:**
- `--no-pch` - Disable precompiled headers
- `--clang` - Use Clang compiler (recommended for speed)
- `--clean` - Force full rebuild
- `--verbose` - Show detailed compilation output
- `--legacy` - Use old CMake system (discouraged)
**Platform Compilation:**
```bash
# Compile examples for specific platforms
uv run ci/ci-compile.py uno --examples Blink
uv run ci/ci-compile.py esp32dev --examples Blink
uv run ci/ci-compile.py teensy31 --examples Blink
```
**WASM Compilation:**
```bash
# Compile any sketch directory to WASM
uv run ci/wasm_compile.py path/to/your/sketch
# Quick compile test (compile only, no browser)
uv run ci/wasm_compile.py examples/Blink --just-compile
# Compile and open browser
uv run ci/wasm_compile.py examples/Blink -b --open
```
## Build Troubleshooting
**For Linker Issues:**
1. Check `tests/cmake/LinkerCompatibility.cmake` first
2. Look for lld-link detection and compatibility functions
3. Check GNU→MSVC flag translation logic
4. Verify warning suppression settings
**For Compiler Issues:**
1. Check `tests/cmake/CompilerDetection.cmake` for detection logic
2. Review `tests/cmake/CompilerFlags.cmake` for flag conflicts
3. Verify optimization settings in `OptimizationSettings.cmake`
**For Build Performance:**
1. Check `tests/cmake/ParallelBuild.cmake` for parallel settings
2. Review LTO configuration in `OptimizationSettings.cmake`
3. Verify linker selection (mold, lld, default)
## 🚨 Critical User Feedback Corrections
**Always Use `uv run python` - NEVER just `python` or `uv run`:**
- ❌ **WRONG**: `python -c "..."`
- ❌ **WRONG**: `uv run -c "..."`
- ✅ **CORRECT**: `uv run python -c "..."`
**Correct Import Paths:**
- ✅ **CORRECT**: `from ci.ci.clang_compiler import ...` (for ci.ci modules)
- ✅ **CORRECT**: `from ci.clang_compiler import ...` (for top-level ci modules, if they exist)
**Never Change Directory:**
- ❌ **WRONG**: `cd ci && python ...`
- ❌ **WRONG**: `cd ci/ci && python ...`
- ✅ **CORRECT**: Stay in project root, use full paths: `uv run python ci/script.py`
**Git-Bash Terminal Compatibility:**
Use leading space for git-bash compatibility:
- ✅ **CORRECT**: ` bash test` (note the leading space)
- ❌ **INCORRECT**: `bash test` (may get truncated to `ash test`)
## Platform Build Information Analysis
**Generate Build Info:**
```bash
# Compile a platform to generate build_info.json
uv run ci/ci-compile.py uno --examples Blink
uv run ci/ci-compile.py esp32dev --examples Blink
```
**Analyze Platform Defines:**
```bash
# Command line tool
python3 ci/ci/build_info_analyzer.py --board uno --show-defines
# Via MCP server
uv run mcp_server.py
# Use build_info_analysis tool with: board="uno", show_defines=true
```
**Compare Platforms:**
```bash
# Command line
python3 ci/ci/build_info_analyzer.py --compare uno esp32dev
# Via MCP
# Use build_info_analysis tool with: board="uno", compare_with="esp32dev"
```
## Symbol Analysis for Binary Optimization
**Analyze specific platform:**
```bash
uv run ci/ci/symbol_analysis.py --board uno
uv run ci/ci/symbol_analysis.py --board esp32dev
uv run ci/ci/symbol_analysis.py --board teensy31
```
**Analyze all available platforms:**
```bash
uv run ci/demo_symbol_analysis.py
```
**Using MCP Server:**
```bash
# Use MCP server tools
uv run mcp_server.py
# Then use symbol_analysis tool with board: "uno" or "auto"
# Or use symbol_analysis tool with run_all_platforms: true
```
**JSON Output:**
```bash
uv run symbol_analysis.py --board esp32dev --output-json
# Results saved to: .build/esp32dev_symbol_analysis.json
```
## Memory Refresh Rule
**🚨 ALL AGENTS: Read ci/AGENTS.md before concluding CI/build work to refresh memory about current Python build system rules and MCP server requirements.**

"module.cpp.o": ["symbol1", "symbol2", ...]
}
}
```
## Supported Platforms
The tool automatically detects and works with any platform that has:
- A `build_info.json` file in `.build/{platform}/`
- Standard toolchain tools (nm, c++filt) in the build info aliases
Successfully tested platforms:
- ✅ **UNO** (AVR) - 51 symbols, 3.7 KB
- ✅ **ESP32DEV** (Xtensa) - 2503 symbols, 231.5 KB
- ✅ **ESP32S3** (Xtensa) - 2831 symbols, 254.6 KB
- ✅ **TEENSY31** (ARM Cortex-M4) - 238 symbols, 10.9 KB
- ✅ **TEENSYLC** (ARM Cortex-M0+) - 241 symbols, 9.1 KB
- ✅ **DIGIX** (ARM Cortex-M3) - 298 symbols, 17.9 KB
- ✅ **STM32** (ARM Cortex-M3) - 311 symbols, 15.6 KB
## Key Improvements
### From ESP32-specific to Generic
**Before (ESP32 only):**
```python
# Hard-coded ESP32 board detection
esp32_boards = ["esp32dev", "esp32", "esp32s2", ...]
# FastLED-specific filtering
if any(keyword in search_text for keyword in [
"fastled", "cfastled", "crgb", "hsv", ...]):
fastled_symbols.append(symbol_info)
```
**After (Generic):**
```python
# Auto-detect any platform with build_info.json
for item in build_dir.iterdir():
if item.is_dir() and (item / "build_info.json").exists():
available_boards.append((build_info_file, item.name))
# No filtering - analyze ALL symbols
symbols.append(symbol_info) # Everything included
```
### Symbol Analysis Improvements
1. **No Classification** - All symbols are included without filtering
2. **Complete Demangling** - All C++ symbols are properly demangled
3. **Platform Agnostic** - Works with any toolchain (AVR, ARM, Xtensa, etc.)
4. **Size-based Sorting** - All results sorted by symbol size for easy optimization targeting
## GitHub Actions Integration
The `symbol_analysis_runner.py` script provides GitHub Actions compatibility:
```yaml
- name: Run Symbol Analysis
run: python ci/symbol_analysis_runner.py --board uno --example Blink
```
This runner:
- Validates build_info.json exists
- Handles errors gracefully with `--skip-on-failure`
- Provides proper exit codes for CI/CD
## Migration from ESP32 Analysis
If you were using the old ESP32-specific analysis:
**Old command:**
```bash
cd ci/ci && python esp32_symbol_analysis.py
```
**New command:**
```bash
cd ci && uv run symbol_analysis.py --board esp32dev
```
The new tool provides all the same information plus:
- Support for more platforms
- ALL symbols instead of just FastLED ones
- Better error handling
- Cleaner output format
## Advanced Usage
### Analyzing Custom Platforms
To add support for a new platform:
1. Ensure the platform builds correctly with PlatformIO
2. Verify `build_info.json` is generated in `.build/{platform}/`
3. Run: `uv run symbol_analysis.py --board {platform}`
### Batch Analysis
```bash
# Analyze all available platforms
uv run demo_symbol_analysis.py
# Analyze specific platforms in sequence
for board in uno esp32dev teensy31; do
uv run symbol_analysis.py --board $board
done
```
### Integration with Build Systems
```python
# In your Python build script
from ci.ci.symbol_analysis import main as analyze_symbols
import sys
# Override arguments
sys.argv = ["symbol_analysis.py", "--board", "uno"]
analyze_symbols()
```
## Troubleshooting
### Common Issues
1. **"build_info.json not found"**
- Solution: Compile the platform first: `uv run ci/ci-compile.py {board} --examples Blink`
2. **"KeyError: 'board_name'"**
- Solution: The board name in the directory doesn't match the key in build_info.json
- Check: `cat .build/{board}/build_info.json | jq 'keys'`
3. **"Tool not found"**
- Solution: The toolchain isn't installed or path is incorrect in build_info.json
### Debug Mode
To debug issues, run with verbose Python output:
```bash
uv run python -v symbol_analysis.py --board uno
```
## Contributing
When adding new features:
1. Maintain platform independence
2. Don't add filtering logic
3. Test on multiple platforms
4. Update this documentation
5. Add tests to verify functionality
## Performance
Platform analysis times (approximate):
- **UNO**: < 1 second (51 symbols)
- **Teensy**: < 2 seconds (238-241 symbols)
- **STM32**: < 3 seconds (311 symbols)
- **ESP32**: < 10 seconds (2503 symbols)
The tool scales well with symbol count and provides progress feedback during demangling.

FastLED Unified Build API
This module provides a unified build system for both unit tests and examples,
centralizing PCH and library building while providing a simple, elegant API.
Key Features:
- Unified API for both unit tests and examples
- Automatic PCH header building and reuse
- Automatic libfastled.a building and reuse
- Organized build directories under .build/
- Efficient multiple target building
- Simple, elegant interface
Usage:
# Unit test building
unit_builder = BuildAPI(
config_file="ci/build_unit.toml",
build_dir=".build/unit",
build_type=BuildType.UNIT_TEST
)
unit_builder.build_targets(["test_json.cpp", "test_color.cpp"])
# Example building
example_builder = BuildAPI(
config_file="ci/build_example.toml",
build_dir=".build/examples",
build_type=BuildType.EXAMPLE
)
example_builder.build_targets(["Blink.ino", "DemoReel100.ino"])

FastLED Unified Build API - Example Usage
This script demonstrates how to use the new unified build API to replace
the old scattered build logic for both unit tests and examples.
Before (scattered logic):
- PCH building logic in multiple places
- libfastled.a building in callers
- Build flags mixed between unit tests and examples
- Manual directory management
After (unified API):
- Single API for both unit tests and examples
- Automatic PCH and library building
- Clean separation of build configurations
- Organized build directory structure

BACKUP: Original concurrent build system - REPLACED by pio ci approach
This file is a backup of the original ci-compile.py that used concurrent builds.
It has been replaced by a simpler pio ci approach in the main ci-compile.py.
The original system used ThreadPoolExecutor to run multiple board compilations
in parallel with build directory creation and artifact recycling.
The new system uses pio ci command directly for each board/example combination,
which is simpler and more straightforward.
This backup is kept for reference and potential future needs.

- Enumerates library source files under src/ (respecting optional filters.exclude_dirs)
- Emits one entry per translation unit with accurate arguments/command fields
Notes:
- This script intentionally avoids project-unit-test driven flags to keep
IntelliSense consistent with the core FastLED library build.

# Docker-based QEMU ESP32 Testing
This directory contains Docker-based QEMU ESP32 emulation tools for FastLED testing.
## Overview
The Docker QEMU solution provides:
- Consistent testing environment across different platforms
- No need for local QEMU installation
- Isolated execution environment
- Support for multiple ESP32 variants (ESP32, ESP32-C3, ESP32-S2, ESP32-S3)
## Components
### Core Files
- `DockerManager.py` - Docker container management utilities
- `qemu_esp32_docker.py` - Main Docker QEMU runner script
- `qemu_test_integration.py` - Integration with existing test framework
- `Dockerfile.qemu-esp32` - Full ESP-IDF + QEMU environment
- `Dockerfile.qemu-esp32-lite` - Lightweight QEMU-only environment
- `docker-compose.yml` - Docker Compose configuration
## Usage
### Quick Start
1. **Run a firmware test with Docker:**
```bash
uv run ci/docker/qemu_esp32_docker.py path/to/firmware.bin
```
2. **Run with specific timeout and interrupt pattern:**
```bash
uv run ci/docker/qemu_esp32_docker.py firmware.bin \
--timeout 60 \
--interrupt-regex "Test passed"
```
3. **Use docker-compose:**
```bash
cd ci/docker
FIRMWARE_DIR=../../.pio/build/esp32dev docker-compose up qemu-esp32
```
### Integration with Test Framework
The Docker QEMU runner integrates with the existing test framework:
```bash
# Check available runners
uv run ci/docker/qemu_test_integration.py check
# Run test with automatic runner selection
uv run ci/docker/qemu_test_integration.py test --firmware path/to/firmware.bin
# Force Docker runner
uv run ci/docker/qemu_test_integration.py test --firmware firmware.bin --docker
```
### Building Docker Images
```bash
# Build lightweight image
docker build -f Dockerfile.qemu-esp32-lite -t fastled/qemu-esp32:lite .
# Build full ESP-IDF image
docker build -f Dockerfile.qemu-esp32 -t fastled/qemu-esp32:full .
# Or use docker-compose
docker-compose build
```
## Docker Images
### Pre-built Images
The runner can use pre-built images:
- `espressif/qemu:esp-develop-8.2.0-20240122` (Official Espressif image)
- `mluis/qemu-esp32:latest` (Community image)
### Custom Images
Two Dockerfiles are provided:
1. **Dockerfile.qemu-esp32-lite** (Recommended)
- Minimal Ubuntu base
- QEMU binaries only
- ~200MB image size
- Fast startup
2. **Dockerfile.qemu-esp32**
- Full ESP-IDF environment
- Development tools included
- ~2GB image size
- Complete toolchain
## Features
### Automatic Fallback
The integration module automatically selects the best available runner:
1. Native QEMU (if installed)
2. Docker QEMU (if Docker available)
3. Error if neither available
### Platform Support
Works on:
- Linux (native Docker)
- macOS (Docker Desktop)
- Windows (Docker Desktop, WSL2)
### Firmware Formats
Supports:
- Direct `firmware.bin` files
- PlatformIO build directories
- ESP-IDF build directories
## Environment Variables
- `FIRMWARE_DIR` - Directory containing firmware files
- `FIRMWARE_FILE` - Specific firmware file to run
- `MACHINE` - ESP32 variant (esp32, esp32c3, esp32s2, esp32s3)
- `FLASH_SIZE` - Flash size in MB (default: 4)
- `TIMEOUT` - Execution timeout in seconds (default: 30)
## Troubleshooting
### Docker Not Found
Install Docker:
- **Windows/Mac**: Install Docker Desktop
- **Linux**: `sudo apt-get install docker.io` or equivalent
### Permission Denied
Add user to docker group:
```bash
sudo usermod -aG docker $USER
# Log out and back in
```
### Image Pull Failed
Check internet connection and Docker Hub access. The runner will automatically try alternative images if the primary fails.
### QEMU Timeout
Increase timeout value:
```bash
uv run ci/docker/qemu_esp32_docker.py firmware.bin --timeout 120
```
## CI/CD Integration
### GitHub Actions
```yaml
- name: Run QEMU Test in Docker
run: |
uv run ci/docker/qemu_esp32_docker.py \
.pio/build/esp32dev/firmware.bin \
--timeout 60 \
--interrupt-regex "Setup complete"
```
### Local CI
```bash
# Install dependencies
uv pip install -r requirements.txt
# Run tests
uv run ci/docker/qemu_test_integration.py test \
--firmware .pio/build/esp32dev/firmware.bin
```
## Development
### Adding New ESP32 Variants
1. Update Dockerfiles with new ROM files
2. Add machine type to runner scripts
3. Test with sample firmware
### Debugging
Run interactively:
```bash
uv run ci/docker/qemu_esp32_docker.py firmware.bin --interactive
```
Enable verbose output:
```bash
docker-compose up qemu-esp32-interactive
```
## Performance
- Docker adds ~2-5 seconds overhead vs native QEMU
- First run pulls image (one-time ~100MB download)
- Subsequent runs use cached image
- Consider using lightweight image for CI/CD

# FastLED JavaScript Linting Tools
This directory contains JavaScript linting tools for the FastLED project, using Node.js + ESLint for **fast** JavaScript validation.
### Via Main Lint Script (Recommended)
```bash
# JavaScript linting is included by default (fast only!)
bash lint
```
## Setup
The fast JavaScript linter is automatically installed during project setup:
```bash
# Installs everything including fast JS linting
./install
```
Or manually install just the JavaScript linter:
```bash
uv run ci/setup-js-linting-fast.py
```
This will:
- Download Node.js binary to `.js-tools/node/`
- Install ESLint to `.js-tools/node_modules/`
- Create ESLint configuration in `.js-tools/.eslintrc.js`
- Create fast linting script `.cache/js-tools/lint-js-fast`
## Philosophy: Fast Only
**JavaScript linting follows a "fast only" policy:**
- ✅ **Fast linting available**: Uses Node.js + ESLint (~0.9 seconds)
- ⚠️ **Fast linting unavailable**: Skips JavaScript linting entirely
- ❌ **No slow fallback**: Fast linting or no linting at all
## Configuration
The fast linter only checks for **critical runtime issues**:
- `no-debugger` - Prevents debugger statements in production
- `no-eval` - Prevents eval() security vulnerabilities
**No style enforcement** - focuses on critical issues only for maximum speed.
## Integration
JavaScript linting is included by default in `bash lint` when fast linting is available.
## Performance
- **Fast linting**: ~0.9 seconds (53x faster than previous solution)
- **Total lint time**: ~1.6 seconds (Python + C++ + JavaScript)
