DazzleNodes Development Scripts

This directory contains development and maintenance scripts for DazzleNodes.

dev_mode.py

Development mode toggle script for managing DazzleNodes development workflow.

Purpose

Manages switching between two modes:

• Dev Mode (symlinks): Direct links to source repositories for rapid development
• Publish Mode (submodules): Git submodules for version control and distribution

Why Two Modes?

Dev Mode Benefits:

• Changes in source repos immediately visible in ComfyUI
• No commit → pull cycle needed during development
• Faster iteration and testing
• Work directly in your node's repository

Publish Mode Benefits:

• Clean git history with submodule tracking
• Version locking to specific commits
• Proper distribution structure
• Ready for git commits and publishing

Requirements

Install required Python packages:

cd C:\code\DazzleNodes\local\scripts
pip install -r requirements.txt

Required packages:

• pyyaml>=6.0 - YAML configuration file parsing

Important: Always run the script with python dev_mode.py, not just dev_mode.py directly. This ensures the correct Python interpreter (with installed dependencies) is used.

Commands

Status Command

Check current state of all nodes:

# Quick status (default)
python dev_mode.py status

# Detailed status with git information
python dev_mode.py status --complete

Quick Mode Output:

• Shows if node is in dev (symlink) or publish (submodule) mode
• Checks if node path exists
• Verifies source repository exists

Complete Mode Output:

• All quick mode information
• Current git branch
• Latest commit
• Uncommitted changes warning
• Git status for both submodule and source repository

Dev Command

Switch nodes to development mode (creates symlinks):

# Switch single node
python dev_mode.py dev smart-resolution-calc
python dev_mode.py dev fit-mask-to-image

# Switch all nodes
python dev_mode.py dev all

What It Does:

1. Backs up existing node directory to nodes_bak/ (with timestamp)
2. Removes existing submodule directory
3. Creates symlink/junction to source repository
4. Verifies symlink creation

After Running:

• Changes in C:\code\smart-resolution-calc-repo\local\ immediately visible in ComfyUI
• No git operations needed for testing
• Restart ComfyUI to see changes

Publish Command

Switch nodes to publish mode (restores submodules):

# Restore single node
python dev_mode.py publish smart-resolution-calc

# Restore all nodes
python dev_mode.py publish all

What It Does:

1. Backs up symlink info to nodes_bak/
2. Removes symlink
3. Restores git submodule with git submodule update --init
4. Submodule points to last committed version

After Running:

• Node directory is git submodule again
• Ready for git commit operations
• Changes in source repo NOT visible until committed and pulled

Global Options

-v, --verbose       # Show detailed operation logs
--dry-run          # Preview changes without making them
--no-backup        # Skip backup creation (dangerous)

Examples:

# See what would happen without making changes
python dev_mode.py --dry-run dev all

# Verbose output for debugging
python dev_mode.py -v dev smart-resolution-calc

# Skip backup (not recommended)
python dev_mode.py --no-backup publish all

Configuration

Edit dev_mode_config.yaml to set defaults:

# Default status mode
status_default_mode: quick  # or "complete"

# Backup before operations
backup_enabled: true

# Verbose output
verbose: false

Configuration Precedence:

1. Command line flags (highest priority)
2. Environment variables
3. Config file
4. Hardcoded defaults (lowest priority)

Environment Variables:

# Set default status mode
export DEV_MODE_STATUS_DEFAULT=complete

# Enable verbose output
export DEV_MODE_VERBOSE=1

Typical Development Workflow

Starting Development Work

# 1. Check current status
python dev_mode.py status

# 2. Switch to dev mode
python dev_mode.py dev all

# 3. Make changes in source repositories
cd C:\code\smart-resolution-calc-repo\local\py
# ... edit smart_resolution_calc.py ...

# 4. Restart ComfyUI to test changes
# Changes are immediately visible!

# 5. Iterate: edit → restart → test

Preparing to Commit

# 1. Commit changes in source repository
cd C:\code\smart-resolution-calc-repo\local
git add -A
git commit -m "Add new feature"

# 2. Switch back to publish mode
cd C:\code\DazzleNodes\local
python dev_mode.py publish all

# 3. Update submodule to latest commit
cd nodes/smart-resolution-calc
git pull

# 4. Commit submodule update in DazzleNodes
cd ../..
git add nodes/smart-resolution-calc
git commit -m "Update smart-resolution-calc to latest"

Safety Features

Automatic Backups:

• All destructive operations create timestamped backups
• Backups stored in nodes_bak/ directory
• Each backup includes timestamp: smart-resolution-calc_20251102_143015

Backup Contents:

• Real directories: Full copy of directory
• Symlinks: Text file with symlink target information

Restore from Backup:

# Manual restoration if needed
cd C:\code\DazzleNodes\local\nodes
rm -rf smart-resolution-calc
cp -r ../nodes_bak/smart-resolution-calc_20251102_143015 smart-resolution-calc

Dry Run Mode:

• Preview all operations before executing
• No files modified
• Shows exact commands that would run

Windows Symlink Details

Symlink Creation:

1. First attempts mklink /D (directory symlink)
2. Falls back to mklink /J (junction) if symlink fails
3. Junctions don't require administrator privileges

Checking Symlink Status:

• Script uses dir /AL to detect symlinks/junctions
• Works with both symlink types
• Handles Windows-specific link behavior

Troubleshooting

"Already in dev mode" but changes not visible

Solution: ComfyUI may be caching. Restart ComfyUI completely.

Symlink creation fails

Possible causes:

• Node directory already exists (script should backup first)
• Source repository not found at expected path
• Permissions issue (junctions should work without admin)

Solution:

# Check status
python dev_mode.py status --complete

# Try with verbose output
python dev_mode.py -v dev smart-resolution-calc

Git submodule restore fails

Possible causes:

• .gitmodules configuration issue
• Submodule URL not accessible
• Git error (see error output)

Solution:

# Manual submodule restore
cd C:\code\DazzleNodes\local
git submodule update --init --recursive

# Check submodule status
git submodule status

Changes not showing after switching modes

Dev Mode → Publish Mode:

• Changes must be committed in source repo first
• Then pulled in submodule
• This is expected behavior

Publish Mode → Dev Mode:

• Restart ComfyUI after switching
• Symlink should point directly to source

Windows Store Python Issues

Symptom: Running dev_mode.py directly fails with missing PyYAML, but python dev_mode.py works fine.

Cause: Windows file association points to Microsoft Store Python stub instead of your real Python installation.

Solution 1: Fix File Association (Recommended)

Run the provided batch script as Administrator:

scripts\fix_python_association.cmd

This will:

• Set .py files to use C:\Python312\python.exe
• Show current and new associations

Solution 2: Disable Windows Store Python Stubs

1. Open Windows Settings
2. Go to Apps > Apps & features > App execution aliases
3. Turn OFF both python.exe and python3.exe toggles
4. This removes the WindowsApps stubs from PATH

Solution 3: Always Use python Command (Workaround)

Just prefix commands with python:

python scripts\dev_mode.py status

Node Mappings

Node mappings are automatically discovered from .gitmodules. No manual configuration needed!

The script parses .gitmodules to find all nodes:

[submodule "nodes/smart-resolution-calc"]
    path = nodes/smart-resolution-calc
    url = /c/code/smart-resolution-calc-repo/local

[submodule "nodes/fit-mask-to-image"]
    path = nodes/fit-mask-to-image
    url = /c/code/ComfyUI-ImageMask-Fix/local

To Add New Node:

1. Add as git submodule: git submodule add <url> nodes/<node-name>
2. That's it! The script automatically discovers it
3. Run python dev_mode.py status to verify
