Bash Completion Script + +- **File**: `completions/backup-scripts-completion.bash` +- **Functions**: + - `_backup_immich_completion()` - Completion for backup-immich.sh + - `_backup_plex_completion()` - Completion for backup-plex.sh + - `_backup_media_completion()` - Completion for backup-media.sh + - `_backup_generic_completion()` - Fallback for other backup scripts + +### 2. Supported Scripts and Flags + +#### backup-immich.sh + +- `--help`, `-h` - Show help message +- `--dry-run` - Preview backup without executing +- `--no-upload` - Skip B2 upload (local backup only) +- `--verbose` - Enable verbose logging + +#### backup-plex.sh + +- `--help`, `-h` - Show help message +- `--auto-repair` - Automatically attempt to repair corrupted databases +- `--check-integrity` - Only check database integrity, don't backup +- `--non-interactive` - Run in non-interactive mode (for automation) +- `--no-parallel` - Disable parallel verification +- `--no-performance` - Disable performance monitoring +- `--webhook=URL` - Send notifications to webhook URL +- `--email=ADDRESS` - Send notifications to email address + +#### backup-media.sh + +- `--help`, `-h` - Show help message +- `--dry-run` - Show what would be backed up without doing it +- `--no-verify` - Skip backup verification +- `--sequential` - Run backups sequentially instead of parallel +- `--interactive` - Ask for confirmation before each backup +- `--webhook URL` - Custom webhook URL for notifications + +### 3. Advanced Features + +#### Intelligent Argument Completion + +- **Webhook URLs**: Auto-suggests `https://notify.peterwood.rocks/lab` +- **Email addresses**: Auto-suggests `peter@peterwood.dev` +- **Flag recognition**: Only shows relevant flags for each script + +#### Path-Aware Completion + +- Works with script name only (if in PATH): `backup-immich.sh --` +- Works with relative paths: `./backup-immich.sh --` +- Works with absolute paths: `/home/acedanger/shell/immich/backup-immich.sh --` + +#### Cross-Shell Support + +- Compatible with bash (native) +- Compatible with zsh (via bashcompinit) + +## Integration with Setup System + +### 1. Modified bootstrap.sh + +- Makes completion script executable during clone/update + +### 2. Modified setup.sh + +- Copies completion script to user's local completion directory +- Ensures proper permissions +- Integrates with zsh configuration + +### 3. Modified .zshrc (dotfiles) + +- Enables bash completion compatibility in zsh +- Sources the completion script automatically +- Loads on every shell session + +## Installation Process + +### Automatic Installation + +1. Run `./setup/bootstrap.sh` or `./setup/setup.sh` +2. Completion is automatically configured and available +3. Works immediately in new shell sessions + +### Manual Installation Steps + +1. Copy script: `cp ~/shell/completions/backup-scripts-completion.bash ~/.local/share/bash-completion/completions/` +2. Make executable: `chmod +x ~/.local/share/bash-completion/completions/backup-scripts-completion.bash` +3. Source in shell: Add `source ~/shell/completions/backup-scripts-completion.bash` to `.zshrc` + +## Testing Results + +Successfully tested all completion functions: + +- ✅ Flag completion for all three main backup scripts +- ✅ Webhook URL completion +- ✅ Email address completion +- ✅ Path-based completion for different invocation methods +- ✅ Registration verification with `complete -p | grep backup` +- ✅ Integration with existing help functionality + +## Usage Examples + +```bash +# Basic flag completion +~/shell/immich/backup-immich.sh -- +# Shows: --help --dry-run --no-upload --verbose + +# Webhook completion +~/shell/plex/backup-plex.sh --webhook +# Shows: https://notify.peterwood.rocks/lab + +# Help verification +~/shell/immich/backup-immich.sh --help +# Shows comprehensive help with all available options +``` + +## Benefits + +### For Users + +- **Faster command entry**: No need to remember exact flag names +- **Reduced errors**: Prevents typos in command-line arguments +- **Better discoverability**: Easy to explore available options +- **Consistent experience**: Works the same way across all backup scripts + +### For Development + +- **Easy to extend**: Simple to add new scripts or flags +- **Maintainable**: Clear structure and well-documented +- **Future-proof**: Works with any script following the naming pattern + +## Files Modified/Created + +### New Files + +- `completions/backup-scripts-completion.bash` - Main completion script +- `completions/README.md` - Comprehensive documentation + +### Modified Files + +- `setup/bootstrap.sh` - Added executable permissions for completion script +- `setup/setup.sh` - Added completion installation during setup +- `dotfiles/.zshrc` - Already had bash completion loading (no changes needed) +- `README.md` - Added tab completion section to main documentation + +## Maintenance + +### Adding New Scripts + +1. Add completion function to `backup-scripts-completion.bash` +2. Register with `complete -F function_name script_name` +3. Test completion works correctly +4. Update documentation + +### Adding New Flags + +1. Update the `opts` variable in the relevant completion function +2. Add argument handling if the flag takes a value +3. Test completion includes the new flag +4. Update help text in the actual script + +## Integration Status + +- ✅ **Implemented**: Full tab completion system +- ✅ **Tested**: All completion functions work correctly +- ✅ **Integrated**: Automatic installation via setup scripts +- ✅ **Documented**: Comprehensive documentation created +- ✅ **Compatible**: Works with both bash and zsh +- ✅ **Future-ready**: Easy to extend for new scripts + +The tab completion system is now fully integrated and ready for use. Users will automatically get intelligent tab completion for all backup script flags after running the setup process.
