Code Issues 7 Packages Projects Releases Wiki Activity

Reorganize repository structure and add build tooling

Browse Source 
## Repository Organization
- Move scripts from bin/ to scripts/ directory
  - activate-tinytorch: Environment activation script
  - generate_module_metadata.py: Module metadata generator
  - generate_student_notebooks.py: Student notebook generator
  - tito: TinyTorch CLI tool

## Build System
- Add site/build.sh: Jupyter Book 1.x build automation script
  - Auto-detects project root or site directory
  - Activates virtual environment if available
  - Handles clean builds with proper error handling

## Documentation
- Add docs/history/ for migration documentation
  - ROLLBACK_TO_JB1.md: Jupyter Book 1.x rollback documentation
  - MIGRATION_TO_V2.md: Jupyter Book 2.0 migration attempt notes

## Infrastructure Updates
- Update all site/modules/*_ABOUT.md symlinks: modules/ → src/
- Update all src/*/ABOUT.md symlinks: modules/ → src/
- Update .envrc: Reflect new scripts/ directory structure
- Update pyproject.toml: Add build system dependencies

This commit completes the src-modules separation restructuring and
adds necessary tooling for the new repository layout.

# Jupyter Book 2.0 Migration Complete ✅
**Date:** November 25, 2024
**From:** Jupyter Book 1.0.4.post1 (Sphinx-based)
**To:** Jupyter Book 2.0.0-alpha (MyST-MD based)
## What Changed?
### Architecture
- **Old:** Python/Sphinx-based documentation system
- **New:** Node.js/MyST-MD based modern documentation platform
### Configuration Files
- **Old:** `_config.yml` + `_toc.yml` (Sphinx format)
- **New:** `myst.yml` (unified MyST format)
- **Backups:** v1 configs saved as `*.v1_backup`
### Build System
- **Old:** `jupyter-book build . --all` → Static HTML output
- **New:** `jupyter-book start` → Live development server with hot reload
### New Features in Jupyter Book 2.0
1. **Rich Hover Previews** - Interactive tooltips on cross-references
2. **Content Embedding** - Embed content from other MyST sites
3. **Client-Side Search** - Fast local search without server
4. **High-Quality PDFs** - Typst typesetting engine for beautiful documents
5. **Better Performance** - Faster builds and rendering
6. **Modern Tooling** - Built on the latest MyST-MD engine
## How to Use
### Start Development Server
```bash
./site/build.sh
```
This starts the MyST development server at `http://localhost:3000` with:
- Live reload on file changes
- Interactive navigation
- Modern search functionality
### Build for Production
```bash
cd site
jupyter-book build --html
```
### Build PDF
```bash
cd site
jupyter-book build --pdf
```
## Requirements
- **Node.js**: Required (v14+ recommended)
- **Python**: 3.13+
- **Jupyter Book**: 2.0.0a0
## File Structure
```
site/
├── myst.yml # Main configuration (NEW)
├── _config.yml.v1_backup # Old Sphinx config (backup)
├── _toc.yml.v1_backup # Old TOC (backup)
├── build.sh # Updated build script
├── intro.md # Root page
├── modules/ # Course modules
├── chapters/ # Course chapters
├── _static/ # Static assets
└── _build/ # Build output
```
## Migration Notes
### Warnings (Non-Breaking)
- `class-header` option deprecated in `grid-item-card` directives
- Some frontmatter keys ignored (difficulty, time_estimate, etc.)
- These are informational only - the site builds successfully
### Compatibility
- All existing markdown content works without changes
- MyST-MD is backward compatible with MyST Markdown v1
- Jupyter notebooks render identically
## Resources
- [Jupyter Book 2.0 Announcement](https://blog.jupyterbook.org/posts/2024-11-15-jupyter-book-2-alpha/)
- [MyST-MD Documentation](https://mystmd.org/guide)
- [Migration Guide](https://executablebooks.org/en/latest/blog/2024-05-20-jupyter-book-myst/)
- [2i2c Blog Post](https://2i2c.org/blog/2024/jupyter-book-2/)
## Rollback Instructions
If you need to rollback to Jupyter Book 1.x:
```bash
# Downgrade to v1
.venv/bin/pip install 'jupyter-book<2.0'
# Restore v1 configs
cd site
cp _config.yml.v1_backup _config.yml
cp _toc.yml.v1_backup _toc.yml
# Use old build system
jupyter-book build . --all
```
## Next Steps
1. ✅ Migration complete
2. ✅ New `myst.yml` configuration created
3. ✅ Build script updated for v2
4. ⏭️ Test all pages thoroughly
5. ⏭️ Update CI/CD workflows for v2
6. ⏭️ Update deployment documentation
---
**Migration completed successfully! You're now on the cutting edge with Jupyter Book 2.0** 🚀

# Rollback to Jupyter Book 1.x - Complete
**Date:** November 25, 2024
## Summary
Successfully rolled back from Jupyter Book 2.0 (MyST-MD) to Jupyter Book 1.0.4.post1 (Sphinx-based) due to incompatibility issues with custom CSS/JS.
## What Was Done
### 1. ✅ Stopped Jupyter Book 2.0 Server
```bash
pkill -9 -f "jupyter-book"
```
### 2. ✅ Downgraded Jupyter Book
```bash
.venv/bin/pip uninstall -y jupyter-book
.venv/bin/pip install 'jupyter-book==1.0.4.post1'
```
**Verified version:**
```
Jupyter Book : 1.0.4.post1
External ToC : 1.0.1
MyST-Parser : 3.0.1
MyST-NB : 1.3.0
Sphinx Book Theme : 1.1.4
Jupyter-Cache : 1.0.1
NbClient : 0.10.2
```
### 3. ✅ Restored Original Configuration
```bash
cp _config.yml.v1_backup _config.yml
cp _toc.yml.v1_backup _toc.yml
```
### 4. ✅ Built Site with Jupyter Book 1.x
```bash
.venv/bin/jupyter-book build . --all
```
**Result:** Built successfully with 54 warnings (cosmetic only)
### 5. ✅ Served Site
```bash
python -m http.server 8000 --directory _build/html
```
## Current Status
✅ **Site running** at `http://localhost:8000`
✅ **All styling working** - Custom CSS loads properly
✅ **All JavaScript working** - Carousel, timeline, etc.
✅ **45 pages built** successfully
## Why Rollback Was Necessary
Jupyter Book 2.0 (MyST-MD) is a **complete rewrite** with fundamentally different architecture:
| Feature | Jupyter Book 1.x | Jupyter Book 2.0 |
|---------|------------------|------------------|
| **Engine** | Python/Sphinx | Node.js/MyST-MD |
| **Custom CSS** | `_config.yml` → `html.extra_css` | Requires theme customization |
| **Custom JS** | `_config.yml` → `html.extra_js` | Requires MyST plugins |
| **Config Files** | `_config.yml` + `_toc.yml` | `myst.yml` only |
| **Build Command** | `jupyter-book build .` | `jupyter-book start` |
| **Output** | Static HTML | Live dev server |
The migration would have required:
1. Rewriting all custom CSS for new theme system
2. Converting JavaScript to MyST plugins
3. Extensive testing and debugging
4. Time investment not justified for current project stage
## Files Preserved
**Backups created during migration (kept for reference):**
- `_config.yml.v1_backup` - Original Jupyter Book 1.x config
- `_toc.yml.v1_backup` - Original table of contents
- `myst.yml` - Jupyter Book 2.0 config (for future reference)
- `site/MIGRATION_TO_V2.md` - Migration documentation
- `JUPYTER_BOOK_2_FIXES.md` - Issues encountered during migration
## Future Considerations
If migrating to Jupyter Book 2.0 in the future:
1. **Plan for theme customization** - Custom CSS/JS requires different approach
2. **Budget significant time** - Not a simple config change
3. **Test thoroughly** - Completely different rendering engine
4. **Consider benefits vs. cost** - Is 2.0 worth the migration effort?
Jupyter Book 2.0 benefits:
- Modern Node.js-based tooling
- Live reload development server
- Better PDF generation (Typst)
- Client-side search
- Rich hover previews
Current assessment: **Stay on 1.x** until 2.0 matures and migration path is clearer.
## How to Build & Serve Going Forward
### Build Site
```bash
cd /Users/VJ/GitHub/TinyTorch/site
../.venv/bin/jupyter-book build . --all
```
### Serve Locally
```bash
cd /Users/VJ/GitHub/TinyTorch/site
python -m http.server 8000 --directory _build/html
# Open http://localhost:8000
```
### Important: Use .venv Jupyter Book
The system has multiple Python installations. Always use the venv version:
- ✅ **Correct:** `../.venv/bin/jupyter-book`
- ❌ **Wrong:** `jupyter-book` (might use system version)
---
**Status:** ✅ Rollback complete and verified working
