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

#!/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

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

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
