This is particularly useful for managing large documents like books, technical documentation, or structured reports. + +## Installation + +The `md-explode` command is built into MarkiTect as part of the markdown commands plugin. No additional installation is required. + +## Usage + +### Basic Syntax +```bash +markitect md-explode [OPTIONS] +``` + +### Parameters + +#### Required +- `INPUT_FILE` - Path to the markdown file to explode + +#### Options +- `--output-dir, -o PATH` - Output directory for exploded files (default: `_exploded/`) +- `--max-depth INTEGER` - Maximum directory nesting depth (default: 10) +- `--dry-run` - Preview what would be created without actually creating files +- `--verbose, -v` - Show detailed output during processing + +## Examples + +### Basic Usage +```bash +# Explode book.md into book_exploded/ directory +markitect md-explode book.md +``` + +### Custom Output Directory +```bash +# Explode into a specific directory +markitect md-explode documentation.md --output-dir ./chapters/ +``` + +### Preview Mode +```bash +# See what structure would be created without creating files +markitect md-explode large-document.md --dry-run --verbose +``` + +### Verbose Output +```bash +# Get detailed information about the explosion process +markitect md-explode technical-guide.md --verbose +``` + +## Input Format + +The command expects markdown files with hierarchical heading structure: + +```markdown +# Part 1: Introduction +Introduction content here. + +## Chapter 1: Getting Started +Chapter content here. + +### Section 1.1: Installation +Installation instructions. + +### Section 1.2: Configuration +Configuration details. + +## Chapter 2: Advanced Topics +Advanced content. + +# Part 2: Reference +Reference material. +``` + +## Output Structure + +The command creates a directory structure that mirrors the document hierarchy: + +``` +document_exploded/ +├── part_1_introduction/ +│ ├── index.md # Part introduction content +│ ├── chapter_1_getting_started/ +│ │ ├── index.md # Chapter content +│ │ ├── section_11_installation.md +│ │ └── section_12_configuration.md +│ └── chapter_2_advanced_topics.md +└── part_2_reference.md +``` + +### Structure Rules + +1. **Directories** are created for headings that have child sections +2. **Files** are created for leaf sections (no children) +3. **Index files** contain the content of parent sections +4. **Nested structure** preserves the document hierarchy +5. **Safe filenames** are generated from heading text + +## Filename Generation + +Headings are converted to filesystem-safe filenames using these rules: + +- **Lowercase conversion**: "Chapter 1" → "chapter_1" +- **Special character removal**: "What's New?" → "whats_new" +- **Unicode normalization**: "Café & Résumé" → "cafe_resume" +- **Number preservation**: "Section 1.1.1" → "section_1_1_1" +- **Path character handling**: "File/Path Issues" → "file_path_issues" +- **Length limiting**: Very long titles are truncated to 100 characters +- **Conflict resolution**: Duplicate names get numbered suffixes + +## Features + +### Front Matter Support +YAML front matter is automatically detected and handled: + +```markdown +--- +title: "My Document" +author: "John Doe" +--- + +# Chapter 1 +Content starts here... +``` + +Front matter is preserved appropriately during the explosion process. + +### Content Preservation +- **Markdown formatting** is fully preserved in exploded files +- **Code blocks** maintain their syntax highlighting +- **Tables, lists, and links** are kept intact +- **Images and media references** are preserved + +### Error Handling +- **Missing files**: Clear error messages for non-existent input files +- **Permission errors**: Graceful handling of filesystem permission issues +- **Malformed markdown**: Robust parsing that handles inconsistent heading levels +- **Empty files**: Appropriate handling of files with no heading structure + +## Advanced Usage + +### Limiting Directory Depth +```bash +# Limit to 3 levels of nesting +markitect md-explode complex-doc.md --max-depth 3 +``` + +When depth is exceeded, deeper sections are flattened into files rather than creating more directories. + +### Working with Large Documents +For very large documents, use dry-run mode first to preview the structure: + +```bash +markitect md-explode huge-manual.md --dry-run --verbose +``` + +This helps you understand the output structure and estimate disk space requirements. + +## Troubleshooting + +### Common Issues + +**"No heading structure found"** +- The markdown file contains no headings (`#`, `##`, etc.) +- Solution: Add headings to structure your document + +**"Permission denied"** +- Insufficient permissions to write to the output directory +- Solution: Check directory permissions or specify a different output location + +**"File already exists"** +- The output directory already exists and contains files +- Solution: Choose a different output directory or remove existing files + +**"Invalid markdown format"** +- The input file is not valid markdown +- Solution: Check the file format and fix any syntax errors + +### Getting Help + +```bash +# Show command help +markitect md-explode --help + +# Show general MarkiTect help +markitect --help +``` + +## Best Practices + +1. **Use descriptive headings** - They become directory and file names +2. **Maintain consistent heading levels** - Don't skip from `#` to `###` +3. **Keep headings concise** - Very long headings result in long filenames +4. **Avoid special characters** in headings when possible +5. **Preview first** - Use `--dry-run` for large documents +6. **Backup originals** - Always keep a copy of your source markdown file + +## Integration + +The `md-explode` command works well with other MarkiTect commands: + +```bash +# Render exploded files to HTML +markitect md-render exploded_directory/ --recursive + +# Create an index of the exploded structure +markitect md-index exploded_directory/ --recursive +``` + +This creates a complete documentation workflow from single file to organized, rendered website. + +## Technical Details + +### Implementation +- **Language**: Python 3.8+ +- **Dependencies**: Click for CLI, unicodedata for filename normalization +- **Parser**: Custom markdown heading parser (no external markdown library required) +- **Performance**: Efficient for documents up to thousands of sections + +### File System Compatibility +- **Cross-platform**: Works on Windows, macOS, and Linux +- **Character encoding**: UTF-8 throughout +- **Filename limits**: Respects filesystem limitations +- **Path length**: Handles deep directory structures appropriately + +## See Also + +- [`md-render`](md-render-command.md) - Render markdown files to HTML +-
