vexy-mkdocs-strip-number-prefix 1.0.4

MkDocs plugin to strip numeric prefixes from page URLs while keeping them in source files

vexy-mkdocs-strip-number-prefix

A lightweight MkDocs plugin that strips numeric prefixes from page URLs while preserving them in source filenames for natural sorting.

Features

• ✅ Clean URLs: Remove numeric prefixes from generated URLs
• ✅ Natural Sorting: Keep prefixes in source files for predictable ordering
• ✅ Collision Detection: Prevent duplicate URLs with configurable strictness
• ✅ Link Rewriting: Automatically update internal markdown links
• ✅ Flexible Patterns: Customize prefix matching with regex patterns
• ✅ Debug Support: Verbose logging for troubleshooting

Installation

Install from PyPI:

uv pip install --system --upgrade vexy-mkdocs-strip-number-prefix

or from source:

pip install git+https://github.com/vexyart/vexy-mkdocs-strip-number-prefix

Quick Start

Add the plugin to your mkdocs.yml:

plugins:
  - search
  - strip-number-prefix

Name your files with numeric prefixes:

docs/
├── 010--introduction.md
├── 020--getting-started.md
├── 030--configuration.md
└── 999--faq.md

Build your site:

mkdocs build

Generated URLs will be clean:

• /introduction/
• /getting-started/
• /configuration/
• /faq/

Configuration

All configuration options with their defaults:

plugins:
  - strip-number-prefix:
      pattern: '^\\d+--'     # Regex pattern for prefix (default: '^\\d+--')
      verbose: false         # Enable debug logging (default: false)
      strict: true           # Fail on slug collisions (default: true)
      strip_links: false     # Strip prefixes from markdown links (default: false)

Pattern Examples

Pattern	Matches	Example
^\\d+--	Any digits + --	123--file.md
^\\d{3}--	Exactly 3 digits + --	001--file.md
^\\d+-	Any digits + -	42-file.md
^\\d+\\.	Any digits + .	1.file.md

Collision Handling

When multiple files would generate the same URL after prefix removal:

plugins:
  - strip-number-prefix:
      strict: true   # Fail build (recommended)
      # strict: false  # Log warning and continue

Link Rewriting

Automatically update internal markdown links:

plugins:
  - strip-number-prefix:
      strip_links: true

File Organization Strategies

Sequential Numbering

docs/
├── 010--introduction.md
├── 020--installation.md
├── 030--configuration.md
├── 040--advanced.md
└── 999--troubleshooting.md

Hierarchical Numbering

docs/
├── 100--getting-started.md
├── 110--installation.md
├── 120--first-steps.md
├── 200--configuration.md
├── 210--basic-config.md
├── 220--advanced-config.md
└── 900--appendix.md

Category Prefixes

docs/
├── 01--intro/
│   ├── 010--overview.md
│   └── 020--quickstart.md
├── 02--guides/
│   ├── 010--setup.md
│   └── 020--deployment.md
└── 99--reference/
    └── 010--api.md

Compatibility

• MkDocs: >= 1.5.0
• Python: >= 3.9
• Works with:
  • Material for MkDocs
  • vexy-mkdocs-awesome-nav
  • vexy-mkdocs-nav-weight
  • Most other MkDocs plugins

Troubleshooting

Duplicate URLs

ERROR: Multiple files would map to 'intro.md': 010--intro.md, 020--intro.md

Solution: Use unique base names:

• 010--intro-basics.md
• 020--intro-advanced.md

Broken Links

When strip_links: false (default), use clean slugs in links:

✅ [Next page](configuration.md)
❌ [Next page](030--configuration.md)

When strip_links: true, both forms work:

✅ [Next page](configuration.md)
✅ [Next page](030--configuration.md)  # Auto-converted

Debug Mode

Enable verbose logging:

plugins:
  - strip-number-prefix:
      verbose: true

This shows:

• File transformations
• URL mappings
• Collision warnings
• Link rewriting
