Rocky Man 📚

Rocky Man is a comprehensive man page hosting solution for Rocky Linux, providing beautiful, searchable documentation for all packages in BaseOS and AppStream repositories across Rocky Linux 8, 9, and 10.

✨ This is a complete rewrite with 60-80% faster performance, modern architecture, and production-ready features!

🎉 What's New in This Rewrite

This version is a complete ground-up rebuild with major improvements:

• 🚀 60-80% faster - Pre-filters packages using filelists.xml (downloads only ~800 packages instead of ~3000)
• 🏗️ Modular architecture - Clean separation into models, repo, processor, web, and utils
• 🎨 Modern UI - Beautiful dark theme with instant fuzzy search
• 🐳 Container ready - Multi-stage Dockerfile that works on any architecture
• ⚡ Parallel processing - Concurrent downloads and HTML conversions
• 🧹 Smart cleanup - Automatic cleanup of temporary files
• 📝 Well documented - Comprehensive docstrings and type hints throughout
• 🔒 Thread safe - Proper locking and resource management
• 🤖 GitHub Actions - Automated weekly builds and deployment

Quick Start

Option 1: Docker (Recommended)

# Build the image
docker build -t rocky-man .

# Generate man pages for Rocky Linux 9.6
docker run --rm -v $(pwd)/html:/data/html rocky-man --versions 9.6

# Generate for multiple versions
docker run --rm -v $(pwd)/html:/data/html rocky-man --versions 8.10 9.6 10.0

# With verbose logging
docker run --rm -v $(pwd)/html:/data/html rocky-man --versions 9.6 --verbose

# Keep downloaded RPMs (mount the download directory)
docker run --rm -it \
  -v $(pwd)/html:/data/html \
  -v $(pwd)/downloads:/data/tmp/downloads \
  rocky-man --versions 9.6 --keep-rpms --verbose

Option 2: Podman (Native Rocky Linux)

# Build the image
podman build -t rocky-man .

# Run with podman (note the :Z flag for SELinux)
podman run --rm -v $(pwd)/html:/data/html:Z rocky-man --versions 9.6

# Interactive mode for debugging
podman run --rm -it -v $(pwd)/html:/data/html:Z rocky-man --versions 9.6 --verbose

# Keep downloaded RPMs (mount the download directory)
podman run --rm -it \
  -v $(pwd)/html:/data/html:Z \
  -v $(pwd)/downloads:/data/tmp/downloads:Z \
  rocky-man --versions 9.6 --keep-rpms --verbose

Option 3: Docker Compose (Development)

# Build and run
docker-compose up

# The generated HTML will be in ./html/
# Preview at http://localhost:8080 (nginx container)

Directory Structure in Container

When running in a container, rocky-man uses these directories inside /data/:

• /data/html - Generated HTML output (mount this to access results)
• /data/tmp/downloads - Downloaded RPM files (temporary)
• /data/tmp/extracts - Extracted man page files (temporary)

By default, RPMs and extracts are automatically cleaned up after processing. If you want to keep the RPMs (e.g., for debugging or multiple runs), mount the download directory and use --keep-rpms:

# This keeps RPMs on your host in ./downloads/
podman run --rm -it \
  -v $(pwd)/html:/data/html:Z \
  -v $(pwd)/downloads:/data/tmp/downloads:Z \
  rocky-man --versions 9.6 --keep-rpms

Note: Without mounting /data/tmp/downloads, the --keep-rpms flag will keep files inside the container, but they'll be lost when the container stops (especially with --rm).

Option 4: Local Development

Prerequisites

• Python 3.9+
• pip (Python package manager)
• mandoc (man page converter)
• Rocky Linux system or container (for DNF)

Installation

# On Rocky Linux, install system dependencies
dnf install -y python3 python3-pip python3-dnf mandoc rpm-build dnf-plugins-core

# Install Python dependencies
pip3 install -e .

Usage

# Generate man pages for Rocky 9.6
python -m rocky_man.main --versions 9.6

# Generate for multiple versions (default)
python -m rocky_man.main --versions 8.10 9.6 10.0

# Custom output directory
python -m rocky_man.main --output-dir /var/www/html/man --versions 9.6

# Keep downloaded RPMs for debugging
python -m rocky_man.main --keep-rpms --verbose

# Adjust parallelism for faster processing
python -m rocky_man.main --parallel-downloads 10 --parallel-conversions 20

# Use a different mirror
python -m rocky_man.main --mirror https://mirrors.example.com/

Architecture

Rocky Man is organized into clean, modular components:

How It Works

1. Package Discovery 🔍

   • Parse repository filelists.xml to identify packages with man pages
   • This is the key optimization - we know what to download before downloading!

2. Smart Download ⬇️

   • Download only packages containing man pages (60-80% reduction)
   • Parallel downloads for speed
   • Architecture-independent (man pages are the same across arches)

3. Extraction 📦

   • Extract man page files from RPM packages
   • Handle gzipped and plain text man pages
   • Support for multiple languages

4. Conversion 🔄

   • Convert troff format to HTML using mandoc
   • Clean up HTML output
   • Parallel processing for speed

5. Web Generation 🌐

   • Wrap HTML in beautiful templates
   • Generate search index with fuzzy search
   • Create multi-version navigation

6. Cleanup 🧹

   • Automatically remove temporary files (configurable)
   • Keep only what you need

Development

Adding New Features

The modular design makes it easy to extend:

• New repositories: Add to config.repo_types in utils/config.py
• Custom templates: Use --template-dir flag or modify templates/
• Additional metadata: Extend Package or ManFile models
• Alternative converters: Implement new converter in processor/
• Different outputs: Add new generator in web/

Running Tests

# Install dev dependencies
pip3 install -e ".[dev]"

# Run tests (when implemented)
pytest

# Type checking
mypy src/

# Linting
ruff check src/

Development Workflow

# 1. Make changes to code
vim src/rocky_man/processor/converter.py

# 2. Test locally in container
podman run --rm -it -v $(pwd):/app rockylinux:9 /bin/bash
cd /app
python3 -m rocky_man.main --versions 9.6 --verbose

# 3. Build Docker image
docker build -t rocky-man .

# 4. Test Docker image
docker run --rm -v $(pwd)/html:/data/html rocky-man --versions 9.6

# 5. Preview output
docker-compose up nginx
# Visit http://localhost:8080

# 6. Commit and push
git add .
git commit -m "feat: your feature description"
git push

Troubleshooting

DNF Errors

Problem: dnf module not found or repository errors

Solution: Ensure you're running on Rocky Linux or in a Rocky Linux container:

# Run in Rocky Linux container
podman run --rm -it -v $(pwd):/app rockylinux:9 /bin/bash
cd /app

# Install dependencies
dnf install -y python3 python3-dnf mandoc rpm-build dnf-plugins-core

# Run the script
python3 -m rocky_man.main --versions 9.6

Mandoc Not Found

Problem: mandoc: command not found

Solution: Install mandoc:

dnf install -y mandoc

Permission Errors in Container

Problem: Cannot write to mounted volume

Solution: Use the :Z flag with podman for SELinux contexts:

podman run --rm -v $(pwd)/html:/data/html:Z rocky-man

For Docker, ensure the volume path is absolute:

docker run --rm -v "$(pwd)/html":/data/html rocky-man

Out of Memory

Problem: Process killed due to memory

Solution: Reduce parallelism:

python -m rocky_man.main --parallel-downloads 2 --parallel-conversions 5

Slow Downloads

Problem: Downloads are very slow

Solution: Use a closer mirror:

# Find mirrors at: https://mirrors.rockylinux.org/mirrormanager/mirrors
python -m rocky_man.main --mirror https://mirror.example.com/rocky/

UTF-8 Decode Errors

Problem: 'utf-8' codec can't decode byte...

Solution: This is now handled with errors='replace' in the new version. The man page will still be processed with replacement characters for invalid UTF-8.

Performance Tips

1. Use closer mirrors - Significant speed improvement for downloads
2. Increase parallelism - If you have bandwidth: --parallel-downloads 15
3. Process one repo at a time - Use --repo-types BaseOS first, then --repo-types AppStream
4. Keep RPMs for re-runs - Use --keep-rpms if testing
5. Run in container - More consistent performance
