# Script Modularization and Consolidation Summary

## ✅ Completed

### 1. Common Library Structure Created

Created `scripts/lib/` directory structure with reusable libraries:

```
scripts/lib/
├── common/          # Common utilities
│   ├── colors.sh    # Color definitions (RED, GREEN, YELLOW, etc.)
│   ├── logging.sh   # Logging functions (log_info, log_error, etc.)
│   ├── paths.sh     # Path definitions (SCRIPT_DIR, PROJECT_ROOT)
│   └── utils.sh     # Utility functions (confirm, require_command, etc.)
├── config/          # Configuration
│   ├── env.sh       # Environment variable loading
│   └── regions.sh   # Region code mapping (single source of truth)
├── azure/           # Azure-specific functions
│   └── cli.sh       # Azure CLI wrapper functions
├── init.sh          # Initialize all libraries (main entry point)
└── README.md        # Library documentation
```

**Total Library Code**: 439 lines of reusable code

### 2. Key Features

#### Single Source of Truth for Region Codes
- All region codes standardized to exactly 3 characters
- Defined once in `lib/config/regions.sh`
- Functions: `get_region_code()`, `get_region_name()`, `get_all_regions()`
- Supports both new (3-char) and old codes for backward compatibility

#### Common Logging Functions
- `log_info()`, `log_warn()`, `log_error()`, `log_debug()`
- `log_success()`, `log_failure()`
- `log_section()`, `log_subsection()`
- Color-coded output with consistent formatting

#### Azure CLI Wrappers
- `ensure_azure_cli()` - Checks installation and login
- `check_azure_cli()`, `check_azure_login()`
- `get_current_subscription()`, `get_current_subscription_name()`
- `set_subscription()`, `get_subscription_id()`

#### Common Utilities
- `require_command()` - Exit if command not found
- `confirm()` - User confirmation prompts
- `is_dry_run()` - Check dry-run mode
- `print_header()`, `print_centered()` - Formatted output

### 3. Documentation Created

- ✅ `scripts/lib/README.md` - Library documentation
- ✅ `scripts/CONSOLIDATION_PLAN.md` - Consolidation strategy
- ✅ `scripts/REFACTORING_GUIDE.md` - Migration guide for existing scripts
- ✅ `scripts/azure/check-naming-conventions.sh.refactored` - Example refactored script

### 4. Script Inventory

**Total Scripts**: 248 shell scripts
- Many with duplicate patterns
- Ready for consolidation following the plan

## 📋 Consolidation Plan

### High-Priority Consolidations

1. **Monitor Scripts** (9 scripts → 1-2 scripts)
   - Consolidate all monitor variants into `monitor-deployment.sh` with modes

2. **Parallel Deployment Scripts** (11 scripts → 1 generic script)
   - Create generic `deploy-parallel.sh` with resource type parameter

3. **Cost Calculation Scripts** (12 scripts → 1 script + library)
   - Create `lib/deployment/costs.sh` library
   - Create single `calculate-costs.sh` script

4. **Verification Scripts** (10 scripts → 1 script)
   - Create `verify-deployment.sh` with resource type options

5. **Contract Deployment Scripts** (8 scripts → 1 generic script)
   - Create generic `deploy-contract.sh` with contract name parameter

### Expected Impact

- **Reduction**: ~50% reduction in script count (248 → ~124 scripts)
- **Maintainability**: Update once, applies everywhere
- **Consistency**: All scripts use same patterns and libraries
- **Documentation**: Clear library structure

## 🔄 Migration Strategy

### Phase 1: Library Adoption (✅ Completed)
1. ✅ Create library structure
2. ✅ Create shared utilities
3. ✅ Create documentation
4. 🔄 Update key scripts (in progress)

### Phase 2: High-Impact Consolidations (Next)
1. Consolidate monitor scripts
2. Consolidate parallel deployment scripts
3. Consolidate cost calculation scripts

### Phase 3: Medium-Impact Consolidations
1. Consolidate verification scripts
2. Consolidate check/status scripts
3. Consolidate contract deployment scripts

### Phase 4: Cleanup
1. Remove deprecated scripts
2. Update Makefile targets
3. Update all documentation

## 📝 Usage Examples

### Quick Start Template

```bash
#!/bin/bash
set -e

SCRIPT_DIR="$(cd "$(dirname "${BASH_SOURCE[0]}")" && pwd)"
source "$SCRIPT_DIR/../lib/init.sh"

# Initialize Azure
ensure_azure_cli || exit 1
set_subscription "$(get_subscription_id)" || true

log_section "Script Title"

# Your script logic here
log_success "Completed"
```

### Using Region Codes

```bash
source "$SCRIPT_DIR/../lib/init.sh"

# Get all regions
while IFS=':' read -r region_name region_code; do
    echo "Processing $region_name ($region_code)..."
done < <(get_all_regions)

# Get specific region code
CODE=$(get_region_code "westeurope")  # Returns "wst"

# Get region name from code
REGION=$(get_region_name "wst")  # Returns "westeurope"
```

### Using Logging

```bash
source "$SCRIPT_DIR/../lib/init.sh"

log_info "Starting process..."
log_warn "This might take a while"
log_error "Failed to connect"
log_success "Completed successfully"
log_section "Deployment Status"
```

## 📚 Next Steps

1. **Migrate High-Priority Scripts**:
   - Start with frequently-used scripts
   - Use `check-naming-conventions.sh.refactored` as template

2. **Create Consolidated Scripts**:
   - Begin with monitor scripts consolidation
   - Then parallel deployment scripts

3. **Update Documentation**:
   - Update all script README files
   - Add migration examples

4. **Testing**:
   - Test each consolidated script
   - Ensure backward compatibility

## 🎯 Benefits

1. **Single Source of Truth**: Region codes, colors, utilities defined once
2. **Consistency**: All scripts use same patterns and libraries
3. **Maintainability**: Update once, applies everywhere
4. **Reduced Duplication**: ~50% reduction in code duplication
5. **Better Error Handling**: Standardized error messages and checks
6. **Easier Testing**: Reusable functions can be unit tested
7. **Improved Documentation**: Clear library structure
