Marker API Feature Development Repository

This repository tracks all file changes during the development of the marker API feature using enhanced implementation guide generators that automatically extract and version control modified files.

Repository Structure

• modified_files/ - Contains copies of all modified/added files preserving original project structure
• implementation_guide.md - Generated comprehensive implementation guide with diff analysis
• file_manifest.md - Detailed manifest of all copied files with metadata
• generate_implementation_guide.sh - Enhanced shell script with file extraction and git integration
• generate_implementation_guide.py - Python script with advanced features and error handling
• deploy_to_test.sh - Development workflow automation script for Docker builds and deployments
• .git/ - Git repository tracking all changes and iterations

Key Features

Quick Start

Basic Usage

# Generate guide for the open-webui project (default branches)
./generate_implementation_guide.sh /path/to/open-webui

# With custom branches
./generate_implementation_guide.sh /path/to/repository feature-branch base-branch

# Example with specific branches
./generate_implementation_guide.sh ../open-webui marker-api-content-extraction main

What Happens When You Run the Script

1. Repository Initialization - Sets up git repository if needed
2. Branch Validation - Verifies both branches exist in target repository
3. File Extraction - Copies all modified/added files from feature branch
4. Structure Creation - Maintains original directory hierarchy
5. Guide Generation - Creates comprehensive implementation guide
6. Manifest Creation - Generates detailed file manifest
7. Auto-Commit - Commits all changes with descriptive message

Development Workflow Automation

# Deploy changes to test environment
./deploy_to_test.sh

What Happens When You Run the Deploy Script

1. Sync Changes - rsync from working repo to test repo (excludes .git)
2. Docker Build - Builds image with CUDA support and specific configuration
3. Image Tagging - Tags the built image for registry
4. Registry Push - Pushes tagged image to Docker Hub
5. Success Notification - Confirms deployment completion

Command Line Arguments

Shell Script

./generate_implementation_guide.sh [repository_path] [feature_branch] [base_branch]

Parameters:

• repository_path - Path to the git repository (required)
• feature_branch - Feature branch name (optional, defaults to "marker-api-content-extraction")

Advanced Features

Git Repository Management

• Auto-initialization - Creates git repo with proper README and .gitignore
• Commit Messages - Descriptive commits with branch info and timestamps
• History Tracking - Complete log of all script executions
• Remote Ready - Can be connected to remote repositories for backup/collaboration

File Extraction Technology

Usage Examples

Development Workflow

# Initial setup - first time running
./generate_implementation_guide.sh /path/to/main-project

# After making changes to feature branch
./generate_implementation_guide.sh /path/to/main-project

# Check what changed
git log --oneline
git show HEAD

# View extracted files
ls -la modified_files/

Different Project Types

# React/Node.js project
./generate_implementation_guide.sh /home/user/react-app feature/new-component main

# Python project
./generate_implementation_guide.sh /projects/python-api feature/auth-system develop

# Multiple feature branches
./generate_implementation_guide.sh /path/to/repo feature-a main
./generate_implementation_guide.sh /path/to/repo feature-b main

Troubleshooting

Common Issues

1. Repository not found

   • Verify the repository path is correct
   • Use absolute paths to avoid confusion
   • Check file permissions

2. Branch not found

   • Check branch names for typos: git branch -a
   • Ensure branches are fetched: git fetch --all
   • Verify branch exists in target repository

3. File extraction failures

   • Check if files exist in the specified branch
   • Verify git repository is not corrupted
   • Ensure sufficient disk space

4. Permission denied

   • Make scripts executable: chmod +x *.sh
   • Check write permissions in script directory
   • Verify git repository permissions

Debug Commands

# Check repository status
cd /path/to/target-repo && git status

# List available branches
cd /path/to/target-repo && git branch -a

# Test diff manually
cd /path/to/target-repo && git diff --stat main feature-branch

# Check script permissions
ls -la generate_implementation_guide.*
