Usage Examples

# Session management
tmxu attach -menu                    # Interactive session picker
tmxu new -templ dev-setup api-proj   # Create from template

# Save/restore workflow
tmxu save                            # Backup all sessions
tmxu restore                         # Restore all sessions
tmxu restore -force                  # Force restore (kills existing)

# Template workflow
tmxu save-template -name mytemplate mysession
tmxu new -templ mytemplate -path ~/projects/app newproject

File Storage

~/.config/tmxu/
├── tmux-sessions.json       # Saved sessions
└── templates/               # Template files
    ├── dev-template.json
    └── web-template.json

All files are JSON and can be version controlled or manually edited.

Tips

• Backup templates: Templates are just JSON files - version control them!
• Use templates for structure: Use save/restore for exact state
• Interactive menu: tmxu attach -menu for quick switching
• Path flexibility: Templates can use any working directory with -path

Requirements

• tmux installed and in PATH
• Go 1.16+ (for building from source)
