Enhances seq_compiler with flexible output modes and beautiful HTML visualization.
## New Features
### 1. Optional C++ Output (Validation Mode)
- Output .cc file is now optional
- Running without output performs validation only
- Useful for checking .seq syntax before committing
- Example: `./seq_compiler assets/demo.seq`
### 2. HTML/SVG Gantt Chart
- New --gantt-html=<file.html> option
- Generates interactive HTML page with SVG timeline
- Much more readable than ASCII version
- Features:
* Color-coded sequences (blue) and effects (teal)
* Invalid time ranges highlighted in red
* Hover tooltips with full effect details
* Time axis with 5-second markers
* Dark theme matching IDE aesthetics
* Vertical time markers for easy reading
* Legend explaining visual elements
### 3. Flexible Command Line
All output modes can be combined:
```bash
# Validation only
./seq_compiler demo.seq
# Code + ASCII Gantt
./seq_compiler demo.seq timeline.cc --gantt=chart.txt
# Code + HTML Gantt
./seq_compiler demo.seq timeline.cc --gantt-html=chart.html
# All outputs
./seq_compiler demo.seq timeline.cc --gantt=t.txt --gantt-html=t.html
```
## HTML Gantt Advantages Over ASCII
✓ Precise pixel-perfect positioning
✓ Scalable vector graphics (zoom without quality loss)
✓ Color coding for priorities and validity
✓ Interactive hover tooltips
✓ Professional dark theme
✓ Much easier to read complex timelines
✓ Can be shared via browser or screenshots
## Implementation Details
- Added ~190 lines for HTML/SVG generation
- Dark theme (#1e1e1e background) matches IDE
- SVG dynamically sized based on sequence count
- Invalid time ranges rendered in red with warning symbol
- Time scale automatically calculated from demo duration
- Hover effects provide detailed information
## Use Cases
- **Validation**: Quick syntax check without code generation
- **ASCII Gantt**: Terminal-friendly, git-friendly text visualization
- **HTML Gantt**: Beautiful presentation for design discussions
- **Combined**: Full toolchain for timeline development
The HTML output answers your question about SVG generation - it turned out
to be straightforward (~190 lines) and provides significantly better
visualization than ASCII art!
## Files Changed
- tools/seq_compiler.cc: Added validation mode and HTML generation
- assets/demo.seq: Updated documentation with new usage examples
- .gitignore: Exclude generated timeline files
Example HTML output: 17KB file with full interactive timeline visualization.

Implements ASCII Gantt chart generation for timeline debugging and visualization.
## New Feature
- Added --gantt=<output.txt> flag to seq_compiler
- Generates visual timeline showing sequences and effects on time axis
- Displays sequence priority, effect priority, and time ranges
- Shows explicit sequence end times with [END=...] markers
- Detects and warns about invalid time ranges (end < start)
## Usage
```bash
./build/seq_compiler assets/demo.seq src/generated/timeline.cc --gantt=timeline.txt
```
## Chart Format
- Time axis in seconds with 5-second markers
- Sequences shown as solid bars (█)
- Effects shown as shaded bars (▓) with sequence background (·)
- Labels include start/end times and priorities
- Legend and documentation at chart end
## Example Output
```
Time (s): 0 5 10 15 20 25 30
|----|----|----|----|----|----|----|
SEQ@0s [pri=0]
████████████████████████████████ (0-30s)
FlashEffect [pri=4]
▓▓·························· (0-1s)
HeptagonEffect [pri=0]
▓▓▓▓▓▓▓▓▓▓▓▓················ (0-10s)
```
## Benefits
- Visualize sequence overlap and layering
- Identify timing conflicts and gaps
- Verify effect priorities render in correct order
- Debug invalid time ranges
- Plan demo choreography visually
## Files Changed
- tools/seq_compiler.cc: Added generate_gantt_chart() function
- assets/demo.seq: Added usage documentation
- .gitignore: Exclude generated demo_timeline.txt
This debugging tool significantly improves timeline development workflow
by providing visual feedback on sequence and effect timing.

Added CMake support for coverage builds and a script to generate HTML reports using lcov on macOS. Also cleaned up .gitignore.

Created a new script, scripts/gen_spectrograms.sh, to robustly convert all audio files in assets/originals to .spec format. The new script is more portable and provides better feedback. Added the newly generated drum and bass samples to the asset list, organizing them by type for clarity. This completes the requested sub-task.
|

Completed the first part of Task #25. Created static libraries for each subsystem (audio, gpu, 3d, util, procedural) and refactored all executables to link against them. This improves modularity and simplifies the build process. Also fixed linker errors related to glfw, wgpu, and miniaudio.

This commit introduces new tools for spectrogram manipulation and visualization, establishes a consistent coding style, and updates project documentation.
Key changes include:
- **Spectrogram Tools:
- : A command-line utility for analyzing WAV/MP3 files into custom spectrogram format and playing back these spectrograms via the synth engine.
- : A command-line tool for visualizing spectrogram files as ASCII art in the console.
- **Coding Style Enforcement:
- Added a configuration file enforcing LLVM-based style with 2-space indentation, no tabs, and an 80-column line limit.
- Renamed all C++ source files from to for project consistency.
- Applied automatic formatting using
exit across the entire codebase.
- **Documentation & Workflow:
- Created to define a commit policy requiring tests to pass before committing.
- Updated with instructions for building and using and , and referenced .
- Updated and to reflect the new tools, audio architecture decisions (real-time additive synthesis, double-buffering for dynamic updates, WAV/MP3 support), coding style, and development workflow.
- **Build System:
- Modified to:
- Include new targets for and under the option.
- Update source file extensions to .
- Add a new end-to-end test for to the suite.
