# Revert Useless Changes
|
||||
|
||||
A functional programming-based tool to automatically detect and revert files with only cosmetic changes (whitespace or comments) in Git repositories.
|
||||
|
||||
## Architecture Overview
|
||||
|
||||
### 🏗️ Core Design Principles
|
||||
|
||||
- **Functional Programming**: Pure functions with minimal side effects
|
||||
- **Rule-Based Analysis**: Extensible rule system for different change types
|
||||
- **Immutable Data Flow**: Data flows through pure transformation functions
|
||||
- **Type Safety**: Full TypeScript coverage with strict typing
|
||||
|
||||
### 📦 Module Structure
|
||||
|
||||
```
|
||||
src/revert-useless-changes/
|
||||
├── types.ts # Core type definitions
|
||||
├── config.ts # Constants and configuration
|
||||
├── utils/ # Pure utility functions
|
||||
│ ├── git.ts # Git operations (getChangedFiles, revertFile, etc.)
|
||||
│ └── file.ts # File system operations (exists, readFile, etc.)
|
||||
├── rules/ # Analysis rules
|
||||
│ ├── index.ts # Rule registry and matching
|
||||
│ ├── whitespace-rule.ts # Detects whitespace-only changes
|
||||
│ └── ast-comment-rule.ts # Detects comment-only changes via AST
|
||||
├── reporter.ts # Output formatting (console, JSON)
|
||||
├── orchestrator.ts # Main workflow coordination
|
||||
├── cli.ts # Command-line interface (Commander.js)
|
||||
└── index.ts # Public API exports
|
||||
```
|
||||
|
||||
## 🔄 Core Workflow

||||

||||

|
||||

|
||||

|

|
||||
J --> I[Display Results]
|
||||
```
|
||||
|
||||
## 🧩 Key Modules
|
||||
|
||||
### 1. **Orchestrator** (`orchestrator.ts`)
|
||||
**Purpose**: Coordinates the entire analysis workflow
|
||||
|
||||
**Core Function**: `execute(config: Config) -> Promise<AnalysisReport>`
|
||||
|
||||
**Flow**:
|
||||
```typescript
|
||||
1. getChangedFiles() -> string[] // Get Git changed files
|
||||
2. filterFiles() -> string[] // Apply include/exclude patterns
|
||||
3. analyzeFiles() -> FileAnalysis[] // Analyze each file with rules
|
||||
4. generateReport() -> AnalysisReport // Create summary statistics
|
||||
5. performReverts() -> AnalysisReport // Revert files (if not dry run)
|
||||
```
|
||||
|
||||
### 2. **Rule System** (`rules/`)
|
||||
**Purpose**: Pluggable analysis rules for different change types
|
||||
|
||||
**Rule Interface**:
|
||||
```typescript
|
||||
interface Rule {
|
||||
name: string; // Unique identifier
|
||||
description: string; // Human-readable description
|
||||
filePatterns: readonly string[]; // Glob patterns for applicable files
|
||||
}
|
||||
|
||||
type RuleAnalyzer = (filePath: string, config: Config) => Promise<RuleResult>
|
||||
```
|
||||
|
||||
**Built-in Rules**:
|
||||
- **WhitespaceRule**: Uses `git diff -w` to detect whitespace-only changes
|
||||
- **AstCommentRule**: Parses JS/TS with AST, removes comments, compares structure
|
||||
|
||||
**Rule Registry**:
|
||||
```typescript
|
||||
getRulesForFile(filePath) -> RuleDefinition[] // Get applicable rules
|
||||
getAllRules() -> RuleDefinition[] // Get all available rules
|
||||
```
|
||||
|
||||
### 3. **Git Utilities** (`utils/git.ts`)
|
||||
**Purpose**: Pure functions for Git operations
|
||||
|
||||
**Key Functions**:
|
||||
```typescript
|
||||
getChangedFiles(options) -> string[] // List modified files
|
||||
hasOnlyWhitespaceChanges(file, options) -> boolean
|
||||
getFileContentAtRef(file, options) -> string // Get file at Git ref
|
||||
revertFile(file, options) -> void // Revert single file
|
||||
findGitRepositoryRoot(startDir) -> string | null // Find Git repo root
|
||||
validateGitRepository(cwd) -> void // Validate Git repo or throw
|
||||
```
|
||||
|
||||
### 4. **File Utilities** (`utils/file.ts`)
|
||||
**Purpose**: Pure functions for file system operations
|
||||
|
||||
**Key Functions**:
|
||||
```typescript
|
||||
exists(path) -> boolean // Check file existence
|
||||
readFile(path) -> string // Read file content
|
||||
matchesPattern(path, patterns) -> boolean // Pattern matching
|
||||
toAbsolutePath(path, base) -> string // Path resolution
|
||||
```
|
||||
|
||||
### 5. **Reporter** (`reporter.ts`)
|
||||
**Purpose**: Output formatting and user feedback
|
||||
|
||||
**Key Functions**:
|
||||
```typescript
|
||||
generateReport(report, config) -> void // Main report output
|
||||
logProgress(message, config) -> void // Progress updates
|
||||
logVerbose(message, config) -> void // Detailed logging
|
||||
logError/logWarning/logSuccess(...) // Status messages
|
||||
```
|
||||
|
||||
## 🔍 Analysis Process
|
||||
|
||||
### File Analysis Flow
|
||||
```typescript
|
||||
1. Check file existence
|
||||
2. Find applicable rules based on file patterns
|
||||
3. Execute each rule analyzer function
|
||||
4. Combine results: shouldRevert = any(rule.shouldRevert)
|
||||
5. Create FileAnalysis with results and matched rule
|
||||
```
|
||||
|
||||
### Rule Execution
|
||||
```typescript
|
||||
// Whitespace Rule
|
||||
hasOnlyWhitespaceChanges(file) -> RuleResult {
|
||||
shouldRevert: git diff -w shows no changes
|
||||
}
|
||||
|
||||
// AST Comment Rule
|
||||
analyzeAstCommentRule(file) -> RuleResult {
|
||||
1. Parse current and previous versions with TypeScript parser
|
||||
2. Remove comment nodes from both ASTs
|
||||
3. Deep compare cleaned ASTs
|
||||
4. shouldRevert: ASTs are structurally identical
|
||||
}
|
||||
```
|
||||
|
||||
## 📊 Data Flow
|
||||
|
||||
### Configuration Flow
|
||||
```
|
||||
CLI Arguments -> Config Object -> All Functions
|
||||
```
|
||||
|
||||
### Analysis Flow
|
||||
```
|
||||
Git Files -> File Filters -> Rule Analysis -> Report Generation -> Output
|
||||
```
|
||||
|
||||
### Types Flow
|
||||
```typescript
|
||||
Config -> FileAnalysis[] -> AnalysisReport -> Console/JSON Output
|
||||
```
|
||||
|
||||
## 🎯 Extension Points
|
||||
|
||||
### Adding New Rules
|
||||
```typescript
|
||||
// 1. Define rule constant
|
||||
export const NEW_RULE: Rule = {
|
||||
name: 'new-rule',
|
||||
description: 'Detects new type of changes',
|
||||
filePatterns: ['**/*.ext']
|
||||
};
|
||||
|
||||
// 2. Implement analyzer function
|
||||
export const analyzeNewRule = async (filePath: string, config: Config): Promise<RuleResult> => {
|
||||
// Analysis logic here
|
||||
return { filePath, ruleName: NEW_RULE.name, shouldRevert: true/false };
|
||||
};
|
||||
|
||||
// 3. Register in rules/index.ts
|
||||
export const AVAILABLE_RULES = [
|
||||
{ rule: WHITESPACE_RULE, analyzer: analyzeWhitespaceRule },
|
||||
{ rule: AST_COMMENT_RULE, analyzer: analyzeAstCommentRule },
|
||||
{ rule: NEW_RULE, analyzer: analyzeNewRule }
|
||||
];
|
||||
```
|
||||
|
||||
### Adding New Output Formats
|
||||
```typescript
|
||||
// Extend reporter.ts
|
||||
export const generateXmlReport = (report: AnalysisReport) => {
|
||||
// XML formatting logic
|
||||
};
|
||||
```
|
||||
|
||||
## 🧪 Testing Strategy
|
||||
|
||||
### Unit Testing
|
||||
- Test each pure function in isolation
|
||||
- Mock Git operations for deterministic tests
|
||||
- Test rule analyzers with sample files
|
||||
|
||||
### Integration Testing
|
||||
- Test full workflow with temporary Git repos
|
||||
- Test CLI argument parsing
|
||||
- Test error handling scenarios
|
||||
|
||||
## 🚀 Usage
|
||||
|
||||
### Programmatic API
|
||||
```typescript
|
||||
import { analyzeAndRevert } from './index';
|
||||
|
||||
const report = await analyzeAndRevert({
|
||||
cwd: '/path/to/project',
|
||||
dryRun: true,
|
||||
verbose: false
|
||||
});
|
||||
```
|
||||
|
||||
### CLI Usage
|
||||
```bash
|
||||
# Analyze and show what would be reverted
|
||||
revert-useless-changes --dry-run --verbose
|
||||
|
||||
# Actually revert files with only whitespace/comment changes
|
||||
revert-useless-changes
|
||||
|
||||
# Analyze specific file types only
|
||||
revert-useless-changes --include "**/*.ts" --include "**/*.js"
|
||||
```
|
||||
|
||||
## 💡 Key Benefits
|
||||
|
||||
1. **Safe Operations**: Dry-run mode prevents accidental changes
|
||||
2. **Intelligent Analysis**: AST-based comment detection, Git-based whitespace detection
|
||||
3. **Extensible**: Easy to add new rule types
|
||||
4. **Fast**: Functional approach enables efficient processing
|
||||
5. **Reliable**: Pure functions are predictable and testable
