# 🚀 AUTO CODE EXTRACTOR 3000™
**The ultimate one-command solution for automated code extraction!**
Stop manually refactoring large files. Let the Auto Code Extractor 3000™ automatically split your 150+ LOC files into clean, modular, lambda-per-file structure with a single command.
## ✨ Features
- 🤖 **Fully Automated** - One command does everything
- 🔍 **Smart Scanning** - Automatically finds files exceeding 150 lines
- 🎯 **Priority-Based** - Processes files by difficulty (high/medium/low)
- 📦 **Batch Processing** - Extract multiple files in controlled batches
- 🛡️ **Safety First** - Dry-run mode, confirmation prompts, git history backup
- 🔧 **Auto-Fix** - Runs linter and fixes imports automatically
- 🧪 **Test Integration** - Runs tests to verify functionality
- 📊 **Progress Tracking** - Detailed reports and JSON results
-**Fast** - AST-based extraction for accuracy and speed
## 🚀 Quick Start
### Preview What Would Be Extracted (Safe!)
```bash
npm run extract:preview
```
This is completely safe - it shows you what would happen without changing any files.
### Extract 5 Files (Recommended First Try)
```bash
npm run extract:quick
```
Extracts 5 high-priority files with confirmation prompt.
### Fully Automated Extraction
```bash
npm run extract:auto
```
Automatically extracts all high-priority files without prompts.
### Extract Everything (Advanced)
```bash
npm run extract:all
```
⚠️ Warning: This processes up to 50 files automatically. Use with caution!
## 📖 Usage
### Basic Command
```bash
npx tsx tools/refactoring/auto-code-extractor-3000.ts [options]
```
### Available Options
| Option | Description | Default |
|--------|-------------|---------|
| `--dry-run` | Preview changes without modifying files | `false` |
| `--priority=<level>` | Filter by priority: `high`, `medium`, `low`, `all` | `high` |
| `--limit=N` | Process only N files | `10` |
| `--batch-size=N` | Process N files at a time | `5` |
| `--skip-lint` | Skip linting phase | `false` |
| `--skip-test` | Skip testing phase | `false` |
| `--auto-confirm` | Skip confirmation prompts | `false` |
| `--verbose` | Show detailed output | `false` |
| `--help` | Show help message | - |
### Examples
#### Safe Exploration
```bash
# Preview all high-priority files
npx tsx tools/refactoring/auto-code-extractor-3000.ts --dry-run
# Preview with verbose output
npx tsx tools/refactoring/auto-code-extractor-3000.ts --dry-run --verbose
# Preview medium-priority files
npx tsx tools/refactoring/auto-code-extractor-3000.ts --dry-run --priority=medium
```
#### Controlled Extraction
```bash
# Extract just 3 files (with confirmation)
npx tsx tools/refactoring/auto-code-extractor-3000.ts --limit=3
# Extract 10 files in batches of 2
npx tsx tools/refactoring/auto-code-extractor-3000.ts --limit=10 --batch-size=2
# Extract medium-priority files
npx tsx tools/refactoring/auto-code-extractor-3000.ts --priority=medium --limit=5
```
#### Automated Workflows
```bash
# Fully automated extraction of high-priority files
npx tsx tools/refactoring/auto-code-extractor-3000.ts --auto-confirm
# Extract all files (up to limit), skip tests for speed
npx tsx tools/refactoring/auto-code-extractor-3000.ts --priority=all --limit=30 --auto-confirm --skip-test
# Verbose automated extraction
npx tsx tools/refactoring/auto-code-extractor-3000.ts --auto-confirm --verbose
```
## 🔄 Workflow
The Auto Code Extractor 3000™ follows a comprehensive workflow:
```
1. 📋 SCANNING
└─ Scans codebase for files >150 LOC
└─ Categorizes by type (component, library, tool, etc.)
└─ Assigns priority levels
2. 🎯 FILTERING
└─ Filters by priority level
└─ Applies file limit
└─ Excludes skipped files (tests, types)
3. 🔍 PREVIEW & CONFIRMATION
└─ Shows files to be processed
└─ Requests confirmation (unless --auto-confirm)
4. 🔨 EXTRACTION (Batch Processing)
└─ Uses AST analysis for accurate code transformation
└─ Extracts functions to individual files
└─ Creates class wrappers for backward compatibility
└─ Generates barrel exports (index.ts)
└─ Replaces original file with re-exports
5. 🔧 LINTING
└─ Runs eslint with auto-fix
└─ Fixes imports and formatting
6. 🧪 TESTING
└─ Runs unit tests
└─ Verifies functionality preserved
7. 📊 REPORTING
└─ Updates progress report
└─ Saves detailed JSON results
└─ Prints summary
8. ✅ COMPLETE
└─ All done! Review and commit
```
## 📁 Output Structure
### Before Extraction
```
lib/
└── utils.ts (300 lines, 10 functions)
```
### After Extraction
```
lib/
├── utils.ts (re-exports everything)
└── utils/
├── functions/
│ ├── validate-email.ts
│ ├── parse-date.ts
│ ├── format-currency.ts
│ ├── calculate-total.ts
│ └── ... (one file per function)
├── UtilsUtils.ts (class wrapper)
└── index.ts (barrel export)
```
### Usage After Extraction
```typescript
// Option 1: Import individual functions (recommended)
import { validateEmail, parseDate } from '@/lib/utils'
// Option 2: Use class wrapper (for those who prefer classes)
import { UtilsUtils } from '@/lib/utils'
UtilsUtils.validateEmail(email)
// Option 3: Direct import from function file
import { validateEmail } from '@/lib/utils/functions/validate-email'
```
## 🎯 Priority Levels
### High Priority (Easiest)
- **Library files** - Pure utility functions, no dependencies
- **Tool files** - Development scripts
-**Recommended to start here**
### Medium Priority
- **DBAL files** - Database abstraction layer
- **Component files** - React components (may need sub-component extraction)
### Low Priority (Complex)
- **Very large files** (>500 lines)
- **Complex interdependencies**
- ⚠️ May need manual review
### Skipped
- **Test files** - Comprehensive coverage is acceptable
- **Type definition files** - Naturally large
## 📊 Reports & Results
### Progress Report
`docs/todo/LAMBDA_REFACTOR_PROGRESS.md`
Markdown report showing:
- All files exceeding 150 lines
- Categorization and priority
- Completion status
- Refactoring recommendations
### Extraction Results
`docs/todo/AUTO_EXTRACT_RESULTS.json`
JSON file containing:
- Timestamp and duration
- Options used
- Summary statistics
- Per-file results with errors
## 🛡️ Safety Features
### 1. Dry-Run Mode
Preview all changes without modifying files:
```bash
npm run extract:preview
```
### 2. Confirmation Prompts
Unless `--auto-confirm` is used, you'll get a 5-second warning before any changes.
### 3. Batch Processing
Process files in small batches to catch issues early:
```bash
npx tsx tools/refactoring/auto-code-extractor-3000.ts --batch-size=2
```
### 4. Git History
All original code is preserved in git history. You can always revert:
```bash
git checkout path/to/file.ts
```
### 5. Automatic Testing
Unless skipped, tests run after extraction to verify functionality.
### 6. Detailed Error Reporting
Any failures are logged with full error messages for troubleshooting.
## 🔧 Troubleshooting
### Import Errors After Extraction
```bash
# Re-run linter
npm run lint:fix
```
### Type Errors
```bash
# Check type errors
npm run typecheck
# Or if using tsx
npx tsc --noEmit
```
### Tests Failing
1. Check if function signatures changed
2. Update test imports to new locations
3. Verify mocks are still valid
### Rollback Changes
```bash
# Revert specific file
git checkout path/to/file.ts
# Revert all changes
git reset --hard HEAD
```
### Tool Not Working
```bash
# Check Node.js version (requires 18+)
node --version
# Install tsx if missing
npm install -g tsx
# Run with verbose output for debugging
npx tsx tools/refactoring/auto-code-extractor-3000.ts --dry-run --verbose
```
## 📝 Recommended Workflow
### Phase 1: Test Drive (2 minutes)
```bash
# 1. Preview what would happen
npm run extract:preview
# 2. Try on 3 files
npx tsx tools/refactoring/auto-code-extractor-3000.ts --limit=3
# 3. Review the output
git diff
# 4. If happy, commit
git add . && git commit -m "refactor: extract 3 files to lambda-per-file structure"
```
### Phase 2: High-Priority Batch (10 minutes)
```bash
# Extract all high-priority files (library & tools)
npm run extract:auto
# Review and test
git diff
npm test
# Commit
git add . && git commit -m "refactor: extract high-priority files"
```
### Phase 3: Medium-Priority (30 minutes)
```bash
# Extract medium-priority files in batches
npx tsx tools/refactoring/auto-code-extractor-3000.ts --priority=medium --limit=10 --auto-confirm
# Review, test, commit
git diff
npm test
git add . && git commit -m "refactor: extract medium-priority files"
```
### Phase 4: Polish (variable)
```bash
# Review any failed extractions
cat docs/todo/AUTO_EXTRACT_RESULTS.json
# Manually handle complex cases
# Update tests if needed
# Final commit
```
## 🎓 Best Practices
### DO ✅
- Start with `--dry-run` to preview
- Begin with high-priority files
- Process in small batches (5-10 files)
- Review changes before committing
- Run tests after extraction
- Commit frequently
### DON'T ❌
- Don't skip the dry-run on first use
- Don't extract everything at once
- Don't commit without reviewing
- Don't skip tests (unless you have a reason)
- Don't panic if something fails - it's recoverable
## 🔗 Related Tools
- **`refactor-to-lambda.ts`** - Generate progress report only
- **`ast-lambda-refactor.ts`** - Extract a single file manually
- **`orchestrate-refactor.ts`** - Manual batch processing (legacy)
## 💡 Tips & Tricks
### Process Specific Files
```bash
# First, mark files in docs/todo/LAMBDA_REFACTOR_PROGRESS.md
# Then run with limit
npm run extract:quick
```
### Skip Slow Steps
```bash
# Skip tests for faster iteration during development
npx tsx tools/refactoring/auto-code-extractor-3000.ts --skip-test
# Skip both lint and tests for maximum speed (not recommended)
npx tsx tools/refactoring/auto-code-extractor-3000.ts --skip-lint --skip-test
```
### Verbose Debugging
```bash
# See exactly what's happening
npx tsx tools/refactoring/auto-code-extractor-3000.ts --dry-run --verbose
```
### Custom Workflow
```bash
# Extract only library files
npx tsx tools/refactoring/auto-code-extractor-3000.ts --priority=high --limit=20 --auto-confirm
# Then extract components separately
npx tsx tools/refactoring/auto-code-extractor-3000.ts --priority=medium --limit=10
```
## 📊 Statistics
Based on the current codebase:
- **Total files >150 LOC:** ~60 files
- **High Priority:** 14 files (library & tools)
- **Medium Priority:** 35 files (components & DBAL)
- **Low Priority:** 2 files (complex hooks)
- **Skipped:** 9 files (tests)
**Estimated Time:**
- High Priority: 5-10 minutes
- Medium Priority: 20-30 minutes
- Total: ~30-40 minutes for complete extraction

🚀 AUTO CODE EXTRACTOR 3000™ 🚀
The ultimate one-command solution for automatically extracting large files (>150 LOC)
into modular lambda-per-file structure.
USAGE:
npx tsx tools/refactoring/auto-code-extractor-3000.ts [options]
OPTIONS:
--dry-run Preview changes without modifying files
--priority=<level> Filter by priority: high, medium, low, all (default: high)
--limit=N Process only N files (default: 10)
--batch-size=N Process N files at a time (default: 5)
--skip-lint Skip linting phase
--skip-test Skip testing phase
--auto-confirm Skip confirmation prompts
--verbose Show detailed output
--help Show this help message
EXAMPLES:
# Preview what would be extracted (safe to run)
npx tsx tools/refactoring/auto-code-extractor-3000.ts --dry-run
# Extract 5 high-priority files with confirmation
npx tsx tools/refactoring/auto-code-extractor-3000.ts --limit=5
# Fully automated extraction of high-priority files
npx tsx tools/refactoring/auto-code-extractor-3000.ts --auto-confirm
# Process all files (use with caution!)
npx tsx tools/refactoring/auto-code-extractor-3000.ts --priority=all --limit=50 --auto-confirm
# Verbose dry run of medium priority files
npx tsx tools/refactoring/auto-code-extractor-3000.ts --dry-run --priority=medium --verbose
WORKFLOW:
1. 📋 Scans codebase for files >150 LOC
2. 🎯 Filters by priority and limit
3. 🔨 Extracts functions into individual files
4. 🔧 Runs linter to fix imports
5. 🧪 Runs tests to verify functionality
6. 📊 Updates progress reports
7. 💾 Saves detailed results
SAFETY FEATURES:
- Dry run mode for safe preview
- Batch processing for incremental work
- Automatic backup via git history
- Confirmation prompts for destructive operations
- Detailed error reporting and recovery
