## How to Use

1. Clone the repository
2. Open the Jupyter notebooks
3. Explore the markdown explanations and code examples
4. Experiment with the code and adapt it to your projects

## Development Tools

### `create_folder.py` - Folder Structure Generator

**Purpose**: Automatically creates folder structures based on course text files.

**How it works**:
- Reads a text file containing course outline
- Detects lines ending with "practices" as course section indicators
- Creates numbered folders for each section found after a "practices" line

**Usage**:
```bash
python create_folder.py <text_file>
```

**Input format example**:
```
Unit 1
4 practices
16 min
Introduction to Tokenization (Rule-Based Tokenization)
Preview
Tokenize Text with NLTK
```

**Output**: Creates folder `1. Introduction to Tokenization (Rule-Based Tokenization)`

---

### `generate-ipynb.sh` - Jupyter Notebook Generator

**Purpose**: Converts structured text files into Jupyter notebooks with proper formatting.

**Features**:
- **Smart Filtering**: Automatically skips lines containing `N practices`, `N min`, or `Preview`
- **Intelligent Naming**: Creates notebook filenames using Unit number + first valid content line
- **Content Structure**: Converts text content to markdown cells with proper heading hierarchy

**Usage**:
```bash
./generate-ipynb.sh <input_text_file>
```

**Output example**:
- `1.Introduction-to-Tokenization-(Rule-Based-Tokenization).ipynb`
- `2.Byte-Pair-Encoding-(BPE)-Subword-Tokenization.ipynb`

---

### `rename_windows_safe.py` - Windows-Safe File Renamer

**Purpose**: Renames files and folders to be safe on Windows file systems.

**What it fixes**:
- Replaces Windows-forbidden characters: `: < > | " * ? \`
- Collapses double spaces and removes trailing dots/spaces
- Guards against Windows reserved names (CON, NUL, COM1–9, LPT1–9)

**Usage**:
```bash
# Dry-run (shows what would change, nothing renamed)
python rename_windows_safe.py <dir> [<dir> ...]

# Actually apply renames
python rename_windows_safe.py --execute <dir> [<dir> ...]
```

**Example**:
```bash
python rename_windows_safe.py --execute doc 40.Building-a-12-Factor-Agents-App-in-Python
```

---

### Workflow Example

1. **Organize Structure**: Use `create_folder.py` to create folder hierarchy
2. **Generate Content**: Use `generate-ipynb.sh` to create notebook files
3. **Manual Enhancement**: Add code cells, explanations, and examples to the notebooks
4. **Cross-platform Safety**: Run `rename_windows_safe.py` to ensure names work on Windows
