**MAIN REMAINING TASK** -- [ ] Profile-guided optimization -- [ ] Link-time optimization -- [ ] Incremental compilation -- [ ] Parallel compilation - -## Technical Decisions Made - -1. **Implementation Language**: Rust (for memory safety and performance) -2. **Parsing Strategy**: Hand-written recursive descent with Pratt parsing -3. **Memory Model**: Automatic Reference Counting with cycle detection -4. **Type System**: Gradual typing with Hindley-Milner inference -5. **Compilation Strategy**: Dual backend (Cranelift for dev, LLVM for prod) -6. **Error Philosophy**: Multiple errors per compilation, helpful messages -7. **Syntax Style**: JavaScript/GDScript inspired for familiarity - -## Open Design Questions - -1. **Concurrency Model**: Actor model vs shared memory with safety? -- Actor model with escape hatches -The actor model aligns perfectly with your philosophy: - -Beginners: "Send messages between actors" is intuitive - like passing notes -Games: Natural fit for game entities communicating -Web: Maps well to web workers and async operations -Safety: Eliminates data races by design -``` -// Simple actor example -actor Player { - let x: f32 = 0 - let y: f32 = 0 - - receive move(dx, dy) { - x += dx - y += dy - } -} - -// But allow shared memory for performance-critical paths -unsafe shared { - let physics_cache = SharedArray() -} -``` -2. **Error Handling**: Result types vs exceptions vs panic? -- Result types with syntactic sugar -Results are more explicit and beginner-friendly than exceptions: - -No invisible control flow -Errors are values, making them less scary -Can add sugar to reduce boilerplate -``` -// Result type approach -fn divide(a: f32, b: f32) -> Result { - if b == 0 { - Err("Division by zero") - } else { - Ok(a / b) - } -} - -// With syntactic sugar using ? operator -fn calculate() -> Result { - let x = divide(10, 2)? // Returns early if error - let y = divide(x, 3)? - Ok(x + y) -} - -// Panic only for unrecoverable errors -assert(index < array.len, "Index out of bounds") -``` -3. **Trait/Interface System**: Structural vs nominal typing? -- Structural typing with optional nominal -Structural typing is more beginner-friendly and flexible: - -"If it walks like a duck..." is intuitive -No need to explicitly implement interfaces -Natural for JavaScript developers -``` -// Structural by default -type Drawable = { - draw(canvas: Canvas) -> () -} - -// Any type with a draw method works -struct Circle { - radius: f32 - - fn draw(canvas: Canvas) { - // implementation - } -} - -// Optional nominal for when you need it -trait GameEntity { - fn update(dt: f32) - fn render() -} - -impl GameEntity for Player { - // explicit implementation -} -``` -4. **Macro System**: Include macros or keep language simple? -- No user-defined macros, but built-in metaprogramming -Macros add significant complexity for beginners. Instead: - -Provide powerful built-in constructs -Code generation through external tools -Template-like features for common patterns -``` -// Built-in derives instead of macros -@derive(Debug, Serialize) -struct Player { - name: String - score: i32 -} - -// Built-in list comprehensions -let doubled = [x * 2 for x in numbers if x > 0] - -// External codegen for complex cases -@generate("protobuf", "schema.proto") -``` -5. **Package Distribution**: Centralized registry vs decentralized? -- Hybrid approach - start centralized, allow mirrors -Begin with simplicity: - -Central registry for discoverability (like npm, crates.io) -Git URLs as escape hatch -Mirror support from day one -``` -// manuscript.toml -[dependencies] -web-framework = "1.2.0" // from registry -game-engine = { git = "https://github.com/user/engine" } -internal-lib = { path = "../libs/internal" } - -[registries] -default = "https://manuscript.script.org" -corporate = "https://internal.company.com/manuscript" -``` -6. **Compile-time Execution**: Const functions vs compile-time interpreter? -- Const functions with clear boundaries -Simpler than full compile-time interpretation: - -Mark functions as @const for compile-time evaluation -Clear rules about what can be const -Useful for configuration and optimization -``` -@const -fn calculate_pi(iterations: i32) -> f32 { - // Can only call other @const functions - // No I/O, no randomness - let pi = // ... calculation - pi -} - -// Evaluated at compile time -const PI = calculate_pi(1000000) - -// Conditional compilation -@const -fn target_os() -> String { - // Returns "windows", "macos", "linux", etc. -} - -if @const(target_os() == "windows") { - // Windows-specific code -} -``` -## Current Focus (Phase 8: Optimizations & Performance) - -With Phases 1-7 now complete (except for minor debugger features), significant progress has been made on optimizations and performance: -

-## Phase 6: Module System Implementation Plan - -With pattern matching fully implemented across all language layers, the next major priority is implementing a comprehensive module and package system for Script. This system should be beginner-friendly while supporting modern development practices. - -### Design Philosophy - -The Script module system follows these principles: -1. **Beginner-Friendly**: Simple, intuitive syntax inspired by familiar languages -2. **Explicit Control**: Clear visibility rules and intentional exports -3. **Path-Based**: Module paths correspond to file system structure -4. **Package-Aware**: Built-in support for external dependencies -5. **Performance-Oriented**: Efficient compilation and resolution - -### Syntax Design - -Based on research of modern languages (Rust, TypeScript, Python, Go), Script will use: - -**Module Declaration:** -```script -// In math/geometry.script -export fn area_circle(radius: f32) -> f32 { - PI * radius * radius -} - -export fn area_rectangle(width: f32, height: f32) -> f32 { - width * height -} - -fn internal_helper() -> i32 { // Not exported - private to module - 42 -} - -export const PI = 3.14159 -``` - -**Import Syntax:** -```script -// Single import -import { area_circle } from "./math/geometry" - -// Multiple imports -import { area_circle, area_rectangle, PI } from "./math/geometry" - -// Import entire module -import * as geo from "./math/geometry" - -// Import with alias -import { area_circle as circle_area } from "./math/geometry" - -// External package import -import { Vec2, Vec3 } from "mathlib" -import { http_get } from "web" -``` - -**Re-export Syntax:** -```script -// In math/mod.script - re-export from submodules -export { area_circle, area_rectangle } from "./geometry" -export { sin, cos, tan } from "./trigonometry" -export * from "./linear_algebra" -``` - -### Implementation Phases -

no compile-time verification that all cases are covered -3. **Pattern Matching Tests**: **ZERO DEDICATED TESTS** - major quality/reliability risk -4. **Guards Implementation**: Incomplete - AST support exists but lowering/semantic analysis gaps -5. **OR Patterns**: Incomplete implementation despite claims - -**MEDIUM PRIORITY:** -6. **Unreachable Pattern Warnings**: Important developer experience feature missing -7. **Documentation**: No examples or usage guides found in codebase -8. **Performance Optimization**: Decision tree optimization not implemented -

+ +The Script programming language is designed with security as a first-class concern. This document outlines the security features, best practices, and considerations when working with Script. + +## Security Features + +### 1. Denial-of-Service (DoS) Protection + +Script includes comprehensive protection against DoS attacks during compilation: + +#### Resource Limits +- **Timeout Protection**: All compilation phases have configurable timeouts +- **Memory Limits**: System memory usage is monitored and bounded +- **Iteration Limits**: Recursive operations have maximum iteration counts +- **Recursion Depth**: Stack overflow protection through depth tracking +- **Specialization Limits**: Generic instantiation explosion prevention + +#### Configuration +```rust +use script_lang::compilation::resource_limits::ResourceLimits; + +// Production environment (secure defaults) +let limits = ResourceLimits::production(); + +// Development environment (more permissive) +let limits = ResourceLimits::development(); + +// Custom limits +let limits = ResourceLimits::custom() + .max_iterations(10_000) + .phase_timeout(Duration::from_secs(30)) + .max_memory_bytes(512 * 1024 * 1024) // 512MB + .build()?; +``` + +### 2. Memory Safety + +#### Array Bounds Checking +- All array accesses include runtime bounds checking +- Negative index detection +- Automatic length validation +- Panic-on-violation with clear error messages + +```script +let arr = [1, 2, 3]; +let val = arr[10]; // Runtime panic: "Array index 10 out of bounds (length: 3)" +``` + +#### Null Pointer Protection +- Automatic null pointer detection in field access +- Runtime validation of object references +- Memory corruption prevention + +### 3. Type Safety + +#### Field Access Validation +- Compile-time field existence checking +- Type-safe field offset calculation +- Prevention of invalid memory access + +#### Generic Type Security +- Specialization explosion prevention +- Type variable limit enforcement +- Constraint system protection + +### 4. Async Runtime Security + +#### Memory Corruption Prevention +- Proper Arc reference counting in async operations +- FFI pointer lifetime tracking +- Race condition elimination + +#### Resource Management +- Bounded async state allocation +- Automatic cleanup of async resources +- Overflow protection in state machines + +## Security Best Practices + +### 1. Compilation Environment + +#### Production Settings +```rust +// Use production resource limits in production +let context = CompilationContext::with_resource_limits( + ResourceLimits::production() +); + +// Enable all security features +let bounds_checker = BoundsChecker::new(BoundsCheckMode::Always); +``` + +#### Development Settings +```rust +// More permissive limits for development +let context = CompilationContext::for_development(); +``` + +### 2. Input Validation + +#### External Code +When processing external Script code, always use restrictive resource limits: + +```rust +let limits = ResourceLimits::custom() + .max_iterations(1_000) // Low iteration limit + .phase_timeout(Duration::from_secs(10)) // Short timeout + .max_memory_bytes(50 * 1024 * 1024) // 50MB limit + .build()?; + +let mut context = CompilationContext::with_resource_limits(limits); +``` + +#### User-Provided Types +- Validate user-defined struct/enum definitions +- Limit nesting depth for complex types +- Prevent recursive type definitions + +### 3. Runtime Security + +#### Array Operations +```script +// Safe array access with bounds checking +fn safe_access(arr: [i32], index: i32) -> Option { + if index >= 0 && index < arr.length { + Some(arr[index]) + } else { + None + } +} +``` + +#### Error Handling +```script +// Use Result types for potentially failing operations +fn divide(a: i32, b: i32) -> Result { + if b == 0 { + Err("Division by zero") + } else { + Ok(a / b) + } +} +``` + +## Security Vulnerabilities and Mitigations + +### 1. Resource Exhaustion Attacks + +**Attack Vector**: Malicious code that consumes excessive compilation resources + +**Mitigation**: Comprehensive resource monitoring and limits +- Timeout enforcement at all compilation phases +- Memory usage tracking and limits +- Iteration count restrictions +- Specialization explosion prevention + +**Example Protection**: +```rust +// This will be caught and prevented +fn recursive_type_bomb() { + // Attempting to create exponential type specializations + // Compiler will abort with security violation +} +``` + +### 2. Memory Corruption + +**Attack Vector**: Buffer overflows through array access or pointer manipulation + +**Mitigation**: Runtime bounds checking and memory safety +- All array accesses validated at runtime +- Negative index detection +- Null pointer protection +- Automatic memory management + +**Example Protection**: +```script +let arr = [1, 2, 3]; +let val = arr[-1]; // Caught: negative index +let val2 = arr[100]; // Caught: index out of bounds +``` + +### 3. Type Confusion + +**Attack Vector**: Exploiting type system weaknesses to access invalid memory + +**Mitigation**: Strong type safety and validation +- Compile-time type checking +- Runtime type validation +- Field access validation +- Generic type constraints + +### 4. Denial of Service + +**Attack Vector**: Code that causes infinite compilation or excessive resource usage + +**Mitigation**: Comprehensive DoS protection +- Phase timeouts prevent infinite compilation +- Memory limits prevent memory exhaustion +- Iteration limits prevent infinite loops in type checking +- Recursion depth limits prevent stack overflow + +## Security Testing + +### 1. Automated Security Tests + +The Script compiler includes comprehensive security tests: + +```bash +# Run all security tests +cargo test security + +# Run resource limit tests specifically +cargo test resource_limits_test + +# Run DoS protection tests +cargo test test_dos_attack_simulation +``` + +### 2. Fuzzing + +For additional security validation, consider fuzzing the compiler: + +```bash +# Install cargo-fuzz +cargo install cargo-fuzz + +# Run parser fuzzing +cargo fuzz run parser_fuzz + +# Run type inference fuzzing +cargo fuzz run inference_fuzz +``` + +### 3. Security Auditing + +Regular security audits should include: + +- Resource limit effectiveness testing +- Memory safety verification +- Attack vector analysis +- Dependency security scanning + +## Security Reporting + +### Vulnerability Disclosure + +If you discover a security vulnerability in the Script language: + +1. **Do not** create a public issue +2. Email security reports to: [security@script-lang.org] +3. Include detailed reproduction steps +4. Allow time for investigation and patching + +### Security Updates + +Security updates will be: +- Released immediately for critical vulnerabilities +- Clearly marked in release notes +- Documented with mitigation strategies +- Backwards compatible when possible + +## Compliance and Certifications + +### Security Standards + +Script follows these security guidelines: +- OWASP Secure Coding Practices +- SANS Top 25 Software Errors prevention +- CWE (Common Weakness Enumeration) mitigation + +### Auditing + +The Script compiler is designed to support: +- SOC 2 compliance requirements +- Security auditing and logging +- Reproducible builds +- Supply chain security + +## Security Configuration Examples + +### High-Security Environment +```rust +let limits = ResourceLimits::custom() + .max_iterations(1_000) // Very restrictive + .phase_timeout(Duration::from_secs(5)) // Short timeout + .total_timeout(Duration::from_secs(15)) // Total limit + .max_memory_bytes(10 * 1024 * 1024) // 10MB only + .max_recursion_depth(50) // Shallow recursion + .max_specializations(100) // Limited generics + .build()?; + +let context = CompilationContext::with_resource_limits(limits); +``` + +### Standard Production Environment +```rust +let limits = ResourceLimits::production(); // Secure defaults +let context = CompilationContext::with_resource_limits(limits); +``` + +### Development Environment +```rust +let limits = ResourceLimits::development(); // More permissive +let context = CompilationContext::for_development(); +``` + +## Monitoring and Alerting + +### Resource Usage Monitoring +```rust +let stats = resource_monitor.get_stats(); +println!("Compilation time: {:?}", stats.compilation_time); +println!("Memory usage: {} bytes", stats.memory_usage); +println!("Type variables: {}", stats.type_variable_count); +``` + +### Security Event Logging +```rust +// Security violations are automatically logged +match context.compile_file(&path) { + Err(Error::SecurityViolation(msg)) => { + log::warn!("Security violation detected: {}", msg); + // Alert security team + } + Ok(module) => { /* Success */ } + Err(other) => { /* Handle other errors */ } +} +``` + +## Conclusion + +The Script language provides comprehensive security features designed to protect against common attack vectors while maintaining usability and performance. By following the guidelines in this document and leveraging the built-in security features, developers can build secure applications with confidence. + +For the latest security updates and announcements, monitor the Script language security advisories and keep your installation up to date. \ No newline at end of file diff --git a/docs/TESTING_README.md b/docs/TESTING_README.md index 51baf8f2..77540b36 100644 --- a/docs/TESTING_README.md +++ b/docs/TESTING_README.md @@ -182,7 +182,7 @@ Example GitHub Actions: ## Learn More -- [Full Testing Documentation](testing_framework.md) +- [Full Testing Documentation](development/TESTING_FRAMEWORK.md) - [Example Tests](../examples/test_basics.script) - [Advanced Examples](../examples/test_stdlib.script) diff --git a/docs/USER_GUIDE.md b/docs/USER_GUIDE.md index 70d11fc9..1f0695b3 100644 --- a/docs/USER_GUIDE.md +++ b/docs/USER_GUIDE.md @@ -1,7 +1,11 @@ # Script Language User Guide +**Version: 0.5.0-alpha** | **Status: ~90% Complete** + Welcome to Script - a modern programming language designed to be simple enough for beginners while powerful enough for production applications.

The design emphasizes: + +- **Explicit over implicit**: Errors are part of the type system +- **Safety by default**: No hidden exceptions or runtime crashes +- **Composability**: Error handling operations can be chained and combined +- **Performance**: Zero-cost abstractions with compile-time optimization +- **Ergonomics**: Concise syntax for common error handling patterns + +### Key Design Decisions + +1. **No exceptions**: Script doesn't have exception handling with try/catch +2. **Explicit Result types**: Functions that can fail return `Result` +3. **Null safety**: Use `Option` instead of null pointers +4. **Composable operations**: Monadic patterns for chaining operations +5. **Early returns**: The `?` operator for convenient error propagation + +## Core Types: Result and Option + +### Result<T, E> + +The `Result` type represents either success (`Ok(T)`) or failure (`Err(E)`). + +```script +// Function that can fail +fn divide(a: i32, b: i32) -> Result { + if b == 0 { + Err("Division by zero") + } else { + Ok(a / b) + } +} + +// Usage +match divide(10, 2) { + Ok(result) => println("Result: {}", result), + Err(error) => println("Error: {}", error), +} +``` + +### Option<T> + +The `Option` type represents either some value (`Some(T)`) or no value (`None`). + +```script +// Function that might not find a value +fn find_user(id: i32) -> Option { + if id == 1 { + Some(User { name: "Alice", id: 1 }) + } else { + None + } +} + +// Usage +match find_user(1) { + Some(user) => println("Found user: {}", user.name), + None => println("User not found"), +} +``` + +## Error Propagation Operator (?) + +The `?` operator provides a concise way to propagate errors up the call stack. + +### Basic Usage + +```script +fn process_data(input: string) -> Result { + let parsed = parse_input(input)?; // Returns early if parse_input fails + let validated = validate_data(parsed)?; // Returns early if validation fails + let processed = transform_data(validated)?; // Returns early if transformation fails + Ok(processed) +} +``` + +### How It Works + +The `?` operator: +1. Evaluates the expression +2. If it's `Ok(value)` or `Some(value)`, unwraps the value +3. If it's `Err(error)` or `None`, returns early with the error/None +4. Automatically converts error types if needed + +### Type Requirements + +The `?` operator can only be used in functions that return: +- `Result` for Result propagation +- `Option` for Option propagation + +## Basic Error Handling Patterns + +### Pattern Matching + +```script +// Exhaustive pattern matching +match parse_number("42") { + Ok(num) => println("Parsed: {}", num), + Err(e) => println("Parse error: {}", e), +} + +// Nested pattern matching +match get_user_data(user_id) { + Ok(Some(data)) => process_data(data), + Ok(None) => println("User has no data"), + Err(e) => println("Error fetching user: {}", e), +} +``` + +### Unwrapping with Defaults + +```script +// Provide default values +let value = parse_number("invalid").unwrap_or(0);

+ + for item in items { + results.push(process_item(item)?); + } + + Ok(results) +} +``` + +## Best Practices + +### 1. Use Descriptive Error Messages + +```script +// Good +fn validate_email(email: string) -> Result { + if email.is_empty() { + return Err("Email address cannot be empty"); + } + + if !email.contains("@") { + return Err("Email address must contain @ symbol"); + } + + Ok(Email::new(email)) +} + +// Bad +fn validate_email(email: string) -> Result { + if email.is_empty() || !email.contains("@") { + return Err("Invalid email"); + } + + Ok(Email::new(email)) +} +``` + +### 2. Fail Fast, Recover Gracefully + +```script +// Fail fast in validation +fn validate_user_input(input: UserInput) -> Result { + validate_username(input.username)?; + validate_email(input.email)?; + validate_password(input.password)?; + Ok(ValidatedInput::new(input)) +} + +// Recover gracefully in application logic +fn handle_user_request(request: Request) -> Response { + match process_request(request) { + Ok(response) => response, + Err(AppError::Validation(e)) => { + Response::bad_request(format!("Validation error: {}", e)) + }, + Err(AppError::Authentication(e)) => { + Response::unauthorized(format!("Auth error: {}", e)) + }, + Err(e) => { + log_error("Internal error: {}", e); + Response::internal_error("Something went wrong") + }, + } +} +``` + +### 3. Use Appropriate Error Types + +```script +// Use Option for "not found" scenarios +fn find_user_by_id(id: i32) -> Option { /* ... */ } + +// Use Result for operations that can fail +fn save_user(user: User) -> Result<(), DatabaseError> { /* ... */ } + +// Use custom error types for domain-specific errors +fn process_payment(payment: Payment) -> Result { /* ... */ } +``` + +### 4.

Permissive Mode (`UnicodeSecurityLevel::Permissive`) + +- **Behavior**: Allows all confusable identifiers without warnings +- **Use Case**: International applications with heavy Unicode usage +- **Impact**: Maximum flexibility, minimal security enforcement + +```rust +let config = UnicodeSecurityConfig { + level: UnicodeSecurityLevel::Permissive, + normalize_identifiers: true, + detect_confusables: true, +}; +``` + +### Feature Toggles + +You can independently control normalization and confusable detection: + +```rust +// Only normalization, no confusable detection +let config = UnicodeSecurityConfig { + level: UnicodeSecurityLevel::Warning, + normalize_identifiers: true, + detect_confusables: false, +}; + +// No Unicode processing at all +let config = UnicodeSecurityConfig { + level: UnicodeSecurityLevel::Permissive, + normalize_identifiers: false, + detect_confusables: false, +}; +``` + +## Performance Characteristics + +### ASCII Fast Path + +Script optimizes for ASCII-only identifiers, which make up the majority of code in most applications: + +- **ASCII identifiers**: Zero Unicode processing overhead +- **Unicode identifiers**: 5-10% normalization overhead +- **Confusable detection**: 10-15% additional overhead with caching benefits + +### Caching System + +Script implements aggressive caching to minimize repeated Unicode operations: + +```rust +// First occurrence: Full Unicode processing +let café = 42; + +// Subsequent occurrences: Cache hit, no processing +let café = 43; +let café = 44; +``` + +### Memory Efficiency + +- **String interning**: Eliminates duplicate Unicode strings +- **Compact caching**: Minimal memory overhead for Unicode metadata +- **Lazy loading**: Unicode data loaded only when needed + +## Best Practices + +### 1.

Through AI integration, Script becomes not just a tool for building applications, but a partner in the development process itself. + +The path to AI-native development reveals itself through the measured implementation of security, the patient building of trust, and the unwavering commitment to both accessibility and safety. Each line of code written with care, each security consideration thoroughly addressed, contributes to a larger vision: programming languages that understand and enhance human creativity rather than merely executing instructions. + +May Script guide many programmers on their journey while demonstrating that the future of development lies not in replacing human insight, but in amplifying it through thoughtful AI integration. \ No newline at end of file diff --git a/kb/README.md b/kb/README.md new file mode 100644 index 00000000..0b211d10 --- /dev/null +++ b/kb/README.md @@ -0,0 +1,70 @@ +# Knowledge Base + +Welcome to your knowledge base! + +## Structure +- `docs/` - Documentation files +- `notes/` - Meeting notes and quick thoughts +- `references/` - Reference materials and specs +- `guides/` - How-to guides and tutorials +- `archive/` - Archived content + +## Important Distinction: kb/ vs src/doc/ + +This knowledge base (`kb/`) serves a different purpose than the `src/doc/` directory: + +- **`kb/` (this directory)**: Internal development documentation + - Tracks implementation status, known issues, and development notes + - Used by developers working on the Script language compiler + - Integrated with MCP tools for project management + - Contains markdown files about compiler architecture and development + +- **`src/doc/`**: Documentation generator for Script language + - Generates HTML documentation from Script source code comments + - Parses `///` and `/** */` doc comments from `.script` files + - Creates user-facing API documentation + - Used by Script language users to document their code + +Both systems are complementary and serve distinct audiences. + +## Usage +```bash +# Read a file +kb read docs/example.md + +# Create a file +kb write docs/new-doc.md "# New Document\n\nContent here" + +# List files +kb list + +# Search content +kb search "keyword" + +# Delete a file +kb delete docs/old-file.md + +# Start MCP server +kb serve + +# Manage database (for graph backend) +kb db start # Start local database +kb db stop # Stop database +kb db status # Check database status +``` + +## CLI Commands +- `kb init` - Initialize a new knowledge base +- `kb read ` - Read a file +- `kb write ` - Write content to a file +- `kb list [directory]` - List files +- `kb search ` - Search for content +- `kb delete ` - Delete a file +- `kb status` - Show status information +- `kb serve` - Start MCP server +- `kb db` - Manage local graph database +- `kb version` - Show version + +--- + +Generated by KB-MCP CLI v2.1.1 \ No newline at end of file diff --git a/kb/active/CODEGEN_SECURITY_AUDIT_ISSUE.md b/kb/active/CODEGEN_SECURITY_AUDIT_ISSUE.md new file mode 100644 index 00000000..d1879100 --- /dev/null +++ b/kb/active/CODEGEN_SECURITY_AUDIT_ISSUE.md @@ -0,0 +1,395 @@ +# Codegen Security Audit & Optimization Issue + +**Issue ID**: CODEGEN-SEC-2025-001 +**Priority**: Critical +**Status**: Open +**Assigned**: Warren Gates +**Created**: 2025-01-13 +**Affects**: src/codegen/ module + +## Executive Summary + +A comprehensive security audit of the `src/codegen/` directory revealed **6 critical security vulnerabilities** and multiple optimization opportunities.

Public API surface (all stdlib functions) + +## Test Quality Standards + +### 1. Test Independence +Each test must be fully independent: +- No shared mutable state +- Clean runtime/environment per test +- No ordering dependencies + +### 2. Test Clarity +Tests should be self-documenting: +```rust +#[test] +fn test_closure_captures_preserve_types() { + // Arrange: Create closure with various typed captures + let captures = vec![ + ("int_val".to_string(), Value::I32(42)), + ("float_val".to_string(), Value::F32(3.14)), + ("string_val".to_string(), Value::String("test".to_string())), + ]; + + // Act: Create closure and retrieve captures + let closure = create_closure_heap("test".to_string(), vec![], captures, false); + let retrieved = extract_closure(&closure); + + // Assert: All types preserved correctly + assert_eq!(retrieved.captured_vars["int_val"], Value::I32(42)); + assert_eq!(retrieved.captured_vars["float_val"], Value::F32(3.14)); + assert_eq!(retrieved.captured_vars["string_val"], Value::String("test".to_string())); +} +``` + +### 3. Error Testing +All error paths must be tested: +```rust +#[test] +fn test_closure_execution_parameter_mismatch() { + let mut runtime = ClosureRuntime::new(); + runtime.register_closure("needs_two", |_| Ok(Value::Null)); + + let closure = create_closure_heap( + "needs_two".to_string(), + vec!["a".to_string(), "b".to_string()], // Expects 2 params + vec![], + false, + ); + + // Call with wrong number of arguments + let result = runtime.execute_closure( + &extract_closure(&closure), + &[Value::I32(1)], // Only 1 argument + ); + + assert!(result.is_err()); + assert!(result.unwrap_err().to_string().contains("expected 2 arguments")); +} +``` + +### 4. Performance Assertions +Performance tests must include assertions: +```rust +#[bench] +fn bench_closure_creation_performance(b: &mut Bencher) { + let baseline_ns = 1000; // Expected max nanoseconds + + b.iter(|| { + create_closure_heap("test".to_string(), vec![], vec![], false) + }); + + assert!( + b.ns_per_iter() < baseline_ns, + "Closure creation too slow: {} ns > {} ns", + b.ns_per_iter(), + baseline_ns + ); +} +``` + +## Continuous Integration + +### Required CI Checks +1. **All tests pass** on Linux, macOS, Windows +2. **Coverage thresholds** met (90% line, 85% branch) +3. **No performance regressions** (benchmarks within 5% of baseline) +4. **Security tests pass** (all attack vectors tested) +5. **Memory leak detection** (valgrind/sanitizers clean) + +### Test Execution +```bash +# Run all closure tests +cargo test closure + +# Run with coverage +cargo tarpaulin --out html --include-tests closure + +# Run benchmarks +cargo bench closure + +# Run security tests +cargo test --test closure_security_tests + +# Run with sanitizers +RUSTFLAGS="-Z sanitizer=address" cargo test closure +``` + +## Maintenance Guidelines + +### Adding New Features +When adding closure features: +1. Write tests FIRST (TDD approach) +2. Cover all new code paths +3. Add integration tests for feature interactions +4. Update benchmarks if performance-relevant +5. Add security tests if external input involved + +### Fixing Bugs +When fixing closure bugs: +1. Write failing test that reproduces bug +2. Fix the bug +3. Verify test now passes +4. Add regression test to prevent reoccurrence +5. Check for similar issues in related code + +### Performance Optimization +When optimizing closures: +1. Benchmark current performance +2. Implement optimization +3. Verify benchmarks show improvement +4. Ensure no functionality regression +5.

Input Validation +Always validate external inputs before processing in async functions: + +```script +async fn process_user_data(input: string) -> Result<(), Error> { + // Validate input size + if input.len() > MAX_INPUT_SIZE { + return Err(Error::InputTooLarge); + } + + // Sanitize input + let sanitized = sanitize_input(input)?; + + // Process safely + await process_sanitized(sanitized) +} +``` + +### 2. Resource Management +Implement proper cleanup and resource limits: + +```script +async fn with_resource() -> Result<(), Error> { + let resource = await acquire_resource()?; + + // Use try-finally pattern for cleanup + try { + await use_resource(resource) + } finally { + await release_resource(resource) + } +} +``` + +### 3. Timeout Protection +Always use timeouts for external operations: + +```script +async fn fetch_with_retry(url: string) -> Result { + let mut attempts = 0; + + while attempts < MAX_RETRIES { + match await_timeout(fetch(url), TIMEOUT_MS) { + Ok(data) => return Ok(data), + Err(TimeoutError) => { + attempts += 1; + await sleep(backoff_ms(attempts)); + } + Err(other) => return Err(other), + } + } + + Err(Error::MaxRetriesExceeded) +} +``` + +### 4. Concurrent Task Management +Limit concurrent operations to prevent resource exhaustion: + +```script +async fn process_batch(items: Vec) -> Vec> { + let mut results = Vec::new(); + + // Process in chunks to limit concurrency + for chunk in items.chunks(MAX_CONCURRENT) { + let tasks = chunk.map(|item| spawn(process_item(item))); + let chunk_results = await join_all(tasks); + results.extend(chunk_results); + } + + results +} +``` + +### 5. Error Propagation +Properly handle and propagate errors: + +```script +async fn multi_step_operation() -> Result<(), Error> { + // Use ? operator for clean error propagation + let step1 = await first_step()?; + let step2 = await second_step(step1)?; + let step3 = await third_step(step2)?; + + Ok(()) +} +``` + +## Performance Tuning + +### 1. Task Granularity +Balance between too many small tasks and too few large tasks: + +```script +// Good: Reasonable task size +async fn process_data_batch(batch: Vec) -> Vec { + let tasks = batch.chunks(100) + .map(|chunk| spawn(process_chunk(chunk))) + .collect(); + + await join_all(tasks) +} + +// Bad: Too fine-grained +async fn process_data_items(items: Vec) -> Vec { + let tasks = items.into_iter() + .map(|item| spawn(process_single(item))) // One task per item + .collect(); + + await join_all(tasks) +} +``` + +### 2. Resource Pooling +Reuse resources to reduce allocation overhead: + +```script +// Connection pool for database operations +let pool = ConnectionPool::new(max_connections: 50); + +async fn query_database(query: string) -> Result { + let conn = await pool.acquire()?; + + try { + await conn.execute(query) + } finally { + pool.release(conn); + } +} +``` + +### 3. Caching Strategies +Implement caching to reduce redundant async operations: + +```script +let cache = AsyncCache::new(max_size: 1000); + +async fn get_user(id: i32) -> Result { + // Check cache first + if let Some(user) = await cache.get(id) { + return Ok(user); + } + + // Fetch from database + let user = await fetch_user_from_db(id)?; + + // Update cache + await cache.set(id, user.clone()); + + Ok(user) +} +``` + +## Troubleshooting + +### Common Issues + +#### 1. Task Spawn Failures +**Symptom**: `spawn()` returns 0 or error +**Causes**: +- Task limit exceeded +- Rate limiting triggered +- System under pressure + +**Solution**: +```script +// Check system state before spawning +if can_spawn_task() { + let handle = spawn(async_work()); +} else { + // Use alternative strategy + await async_work(); // Execute directly +} +``` + +#### 2. Timeout Errors +**Symptom**: Operations timing out unexpectedly +**Causes**: +- Network latency +- Resource contention +- Insufficient timeout values + +**Solution**: +```script +// Adaptive timeout based on conditions +let timeout = if is_peak_hours() { + TIMEOUT_MS * 2 // Double timeout during peak +} else { + TIMEOUT_MS +}; + +await_timeout(operation(), timeout) +``` + +#### 3. Memory Limit Errors +**Symptom**: Task memory allocation failures +**Causes**: +- Large data structures +- Memory leaks +- Insufficient limits + +**Solution**: +```script +// Stream processing for large data +async fn process_large_file(path: string) -> Result<(), Error> { + let stream = await open_stream(path)?; + + while let Some(chunk) = await stream.read_chunk()? { + await process_chunk(chunk)?; + // Chunk is dropped here, freeing memory + } + + Ok(()) +} +``` + +### Debug Techniques + +#### 1.

Attacker creates reference to object +2. Object is freed by another thread +3. Attacker accesses freed memory +4. Memory corruption or information disclosure +``` + +**Script Protection**: +```rust +// Generation counters prevent use-after-free +struct SecureRcWrapper { + generation: u64, // Prevents stale references + type_id: TypeId, // Validates type consistency + object_size: usize, // Enables bounds checking +} + +// All access validated +fn access_object(&self) -> Result<&T, SecurityError> { + self.validate_generation()?; // Prevent use-after-free + self.validate_type()?; // Prevent type confusion + self.validate_bounds()?; // Prevent buffer overflow + // Safe access granted +} +``` + +#### 2. **Memory Corruption Attacks** + +**Attack Pattern**: +``` +1. Attacker triggers buffer overflow +2. Overwrites adjacent memory structures +3. Corrupts object metadata or code pointers +4. Achieves code execution or privilege escalation +``` + +**Script Protection**: +```rust +// Comprehensive bounds checking +fn write_to_memory(&self, offset: usize, data: &[u8]) -> Result<(), SecurityError> { + // Validate write bounds + if offset + data.len() > self.object_size { + return Err(SecurityError::OutOfBounds); + } + + // Validate alignment + if (self.ptr.as_ptr() as usize + offset) % alignment != 0 { + return Err(SecurityError::InvalidAlignment); + } + + // Validate write permissions + if !self.has_write_permission() { + return Err(SecurityError::AccessDenied); + } + + // Safe write + unsafe { /* validated write operation */ } +} +``` + +#### 3. **Denial of Service Attacks** + +**Attack Pattern**: +``` +1. Attacker creates excessive allocations +2. Memory or CPU resources exhausted +3. System becomes unresponsive +4. Legitimate users cannot access service +``` + +**Script Protection**: +```rust +// Resource limit enforcement +fn allocate_object(&self, size: usize) -> Result { + // Check memory limits + self.resource_monitor.record_allocation(size)?; + + // Check allocation count limits + if self.allocation_count.load(Ordering::Relaxed) > MAX_ALLOCATIONS { + return Err(ResourceViolation::AllocationLimitExceeded); + } + + // Check memory pressure + if self.resource_monitor.is_under_memory_pressure() { + self.trigger_emergency_collection()?; + } + + // Proceed with controlled allocation +} +``` + +#### 4. **Race Condition Exploits** + +**Attack Pattern**: +``` +1. Attacker identifies race condition window +2. Triggers concurrent operations +3. Exploits timing to bypass security checks +4. Achieves unauthorized access or corruption +``` + +**Script Protection**: +```rust +// Lock-free atomic operations +fn safe_reference_increment(&self) -> Result<(), SecurityError> { + let mut retries = 0; + const MAX_RETRIES: usize = 10; + + loop { + let current = self.strong_count.load(Ordering::Acquire); + + // Validate state + if current == 0 { + return Err(SecurityError::ObjectFreed); + } + + // Prevent overflow + let new_count = current.checked_add(1) + .ok_or(SecurityError::CounterOverflow)?;

You can utilize React to power your game's UI, or you can hook up [`react-three-fiber`](https://github.com/pmndrs/react-three-fiber) or [`react-pixi`](https://github.com/inlet/react-pixi) to power your whole game. + +Of course, React adds additional overhead and can require a lot of imperative bailouts (i.e. `ref`s) to render realtime visualizations - but you get to decide where to draw the line for your game. + +For more details, take a look at the [`@0g/react`](https://github.com/a-type/0g/tree/master/packages/react) package after you've read up on the basics of `0G`. + +## Docs + +`0G` has an "ECS inspired" architecture. It's probably not accurate to call it an ECS - it doesn't follow all the rules, and in particular it doesn't maintain the kinds of performance optimizations which form a core part of what "ECS" means (Components in `0G` are objects, not raw data - so JavaScript can't optimize their memory locations like you could in a lower-level implementation). + +If you're familiar with ECS, some of these concepts should also feel familiar - but be sure to read on for details about the specifics of `0G`'s usage and patterns! + +### Components + +```tsx +class Transform extends Component({ + x: 0, + y: 0, + angle: 0, +}) { + get position() { + return { + x: this.x, + y: this.y, + }; + } +} + +class Rigidbody extends State({ + value: new PhysicsLibrary.Rigidbody(), +}) {} +``` + +To start modeling your game behavior, you'll probably first begin defining Components. + +Components are where your game state lives. The purpose of the rest of your code is either to group, change, or render Components. + +Components come in two flavors: + +- _Component_ (persistent): Serializeable and runtime-editable1, this data forms the loadable "scene." + - Example: Store the configuration of a physics rigidbody for each character +- _State_ (ephemeral): Store any data you want. Usually these components are derived from persistent Components at initialization time. + - Example: Store the runtime rigidbody created by the physics system at runtime + +1 Runtime editing is not yet supported... except in the devtools console. + +You'll notice the syntax for defining a Component is a bit odd. A Component, like `Transform` above, is a class constructor which inherits from a class generated by calling the function `Component` (or `State`). + +This unique syntax allows `0G` to correctly type all the data in your Components thoughout your game and provide advanced DX. + +To the `Component/State` function, we pass the default values. The object we pass to this function will define what data is serialized in a `Component`. + +In our actual class body, we can define additional properties or methods to improve the usage of our Component. I like to put computed data in properties here to reduce duplicated stored state and make things simpler in my game logic. + +#### Component Change Tracking + +`0G` can track changes you make to Components when you update it in certain ways. While not often needed, this can help to optimize certain parts of your game which might only need to run when a Component changes. + +To inform `0G` that your component data has changed, you can do one of two things: + +1. Set `.updated = true` on your component +2. Make your changes within an `.update(comp => { comp.foo = 'bar'; })` block + +Most of the time, 1 is sufficient and straightforward. + +When you tell `0G` a Component has been updated, anything 'listening' for changes won't be informed immediately. The new updated flag state will be cached until the next frame. + +### Entities + +```tsx +const transform = entity.get(stores.Transform); +transform.x = 100; +``` + +As in classic ECS, Entities are identifiers for groupings of Components. Each Entity has an ID. In `0G`, an Entity object provides some convenience tools for retrieving its components, with full TypeScript support. + +There are a few ways to "get" Entities in `0G`. The most common is to get them from a Query (see below). Sometimes, you may know an Entity's ID and want to grab it directly. For that you can use `Game.get`: + +```ts +const ent = game.get(23); +``` + +When you use a Query to find Entities, the resulting Entities will be fully typed with guarantees on known Components the Entity must possess. When you get an Entity directly from the game, all Components are considered nullable and you'll need to test to see if they are present before referencing them. + +```ts +const ent = game.get(23); +const transform = ent.get(Transform); +// null safety is required - Transform may not exist on entity 23 +const x = transform?.x ?? 0; +``` + +There may be more to say about Entities, but it's better to see them in the context of Queries and Systems. + +### Queries + +```tsx +[Player, changed(Transform), not(Body)]; +``` + +It's important, as a game developer, to find Entities in the game and iterate over them. Generally you want to find Entities by certain criteria. In `0G` the primary criteria is which Components they have associated. + +Queries are managed by the game, and they monitor changes to Entities and select which Entities match your criteria. For example, you could have a Query which selects all Entities that have a `Transform` and `Body` store to do physics calculations. + +In practice, you'll usually define Queries by creating an array of Component constructors and Filters when constructing a System or Effect. + +#### Query Filters + +There are a number of filters available on `0G` you can use to select Entities: + +- `not(Component)`: The Entity does not have `Component` associated with it +- `any(ComponentA, ComponentB)`: The Entity has at least one of the listed Components associated with it +- `changed(Component)`: The query will only include an Entity if the specified Component changed last frame +- `has(Component)`: The Entity has this Component. Implied if you just pass in `Component` directly + +`changed` is probably the most interesting. It relates to the change tracking mentioned above in the Components section. An Entity will only appear in a Query with a `changed` filter if the Component specified by that filter was flagged as changed last frame - either `.updated = true` was called, or a change was made via `.update(...)`. + +### Systems + +```tsx +const demoMove = makeSystem([Transform], (entity, game) => { + const transform = entity.get(Transform); + // see the Resources section + const keyboard = game.resourceManager.immediate('keyboard'); + if (keyboard.getKeyPressed('ArrowLeft')) { + transform.x -= 5; + } else if (keyboard.getKeyPressed('ArrowRight')) { + transform.x += 5; + } +}); +``` + +Systems are where your game logic lives. They utilize Queries to access Entities in the game which meet certain constraints. Using those Queries, they can iterate over matching entities each frame, performing logic. + +A System has a Query definition (an array of Component constructors and Filters), and a callback. The callback is passed an Entity which matches the Query, and the Game itself. + +Inside the callback, reference the Entity's Components to gather data about it, and modify them to change the game state. You can also utilize `game` to add new Components, remove Components, create new Entities, etc. + +### Effects + +```ts +const manageModel = makeEffect([ModelSource], async (entity, game) => { + const { src } = entity.get(ModelSource); + const vertices = await game.resourceManager.load(src); + const modelGeometry = new ThreeDLibrary.Geometry({ vertices }); + game.add(entity.id, Mesh, { geometry: modelGeometry }); + + return () => { + game.remove(entity.id, Mesh); + modelGeometry.dispose(); + }; +}); +``` + +Effects are specialized Systems which give you a convenient way to express side-effects and asynchronous logic as part of your game. + +An effect specifies a Query and a callback. The callback receives an Entity which matches the Query, and the Game (like Systems). + +However, unlike Systems, the callback is only called once - when the Entity first matches the provided Query. The callback can also be `async` and await long-running tasks like asset loading. + +The callback can also return a new function. This returned function will be run during "cleanup" - when the Entity in question is first removed from the Query. + +Effects are great for modeling dependent state! Dependent state takes a form like "Any Entity with a BodyConfig component should also get a Body." These relationships are easy to express by defining the appropriate Query and writing a callback to create and assign the related Component, then unassign it when the Entity no longer satisfies the Query. + +### Resources + +The Game has some tools to help you manage shared global state and asset loading and management. + +#### Globals + +Globals are a big key-value store of anything you might need to reference from all over your game. Good candidates for global state are a Three.JS scene, a physics simulation, or smaller one-off state items like timers which might be awkward and heavy to implement with Components. + +More than just a dumb key-value, though, Globals allows you to `await` the presence of an expected global value. This is useful in Effects! For example, perhaps you want to have an Entity which controls the physics simulation on a per-scene basis. This Entity would then load the global physics simulation at some unspecified time - perhaps on the first frame, perhaps later. All Entities with physics objects associated with them would need to wait for this simulation to be bootstrapped - then will have to `await` it! + +```ts +const manageSimulation = makeEffect( + [PhysicsWorldConfig], + async (entity, game) => { + const config = entity.get(PhysicsWorldConfig); + game.globals.resolve('physicsWorld', new PhysicsLibrary.World(config)); + return () => { + game.globals.remove('physicsWorld'); + }; + }, +); + +const manageBody = makeEffect([BodyConfig], async (entity, game) => { + const simulation = await game.globals.load('physicsWorld'); + // now the world has been loaded and we can create the Body + const body = simulation.createBody(); + game.add(entity.id, Body, { value: body }); + return () => { + simulation.destroyBody(body); + game.remove(entity.id, Body); + }; +}); +``` + +Waiting for globals is a simple but powerful way to encode these kinds of dependencies in your Effects. You're also free to implement more than one way to define a global without changing the rest of the game logic which relies on it. + +#### Assets + +Assets are similar to Globals, but rather than resolving them manually, you provide specific named asset loaders up-front to your Game. For example, you might have an asset loader that loads `.OBJ` files. + +When an Asset is awaited for the first time, your loader kicks in and loads it for you, resolving the promise when loading is complete. + +Assets are cached once they're loaded the first time. Any subsequent waits on an asset will resolve immediately with the cached value. + +```ts +const manageModel = makeEffect([ModelSource], async (entity, game) => { + const { src } = entity.get(ModelSource); + const vertices = await game.assets.load('.obj', src); + const modelGeometry = new ThreeDLibrary.Geometry({ vertices }); + game.add(entity.id, Mesh, { geometry: modelGeometry }); + + return () => { + game.remove(entity.id, Mesh); + modelGeometry.dispose(); + }; +}); +``` + +#### Typings for Resources + +While `0G` can infer a lot of typings for you, globals are harder to do well. + +To achieve type-safety for Globals and Assets, you can manually define their shape by using `declare` in your game code to extend the interfaces which `0G` uses to define them: + +```ts +import { AssetLoader } from '0g'; + +declare package '0g' { + interface Globals { + physicsWorld: PhysicsEngine.Simulation; + scene: ThreeJS.Scene; + } + + interface AssetLoaders { + '.obj': AssetLoader; + '.jpg': AssetLoader; + } +} +``` + +With these type definitions in place, hopefully you'll see stricter type-checking for references to Globals or Assets. diff --git a/node_modules/0g/dist/Archetype.d.ts b/node_modules/0g/dist/Archetype.d.ts new file mode 100644 index 00000000..159e4709 --- /dev/null +++ b/node_modules/0g/dist/Archetype.d.ts @@ -0,0 +1,44 @@ +import { EventSubscriber } from '@a-type/utils'; +import { ComponentHandle } from './Component2.js'; +import { Entity } from './Entity.js'; +export type ArchetypeEvents = { + entityAdded(entity: Entity): any; + entityRemoved(entityId: number): any; +}; +/** + * Archetype is a group of Entities which share a common component signature. + * Archetypes are the storage system for Entities; each Entity traces back to an Archetype's + * entities array.

By default we'll use `name`. +- `checked`: If `true`, the option will be checked by default. +- `disabled`: Disallow the option from being selected.

npmyarn
+ +```sh +npm install @inquirer/core +``` + + + +```sh +yarn add @inquirer/core +``` + +
+ +# Usage + +## Basic concept + +Visual terminal apps are at their core strings rendered onto the terminal. + +The most basic prompt is a function returning a string that'll be rendered in the terminal. This function will run every time the prompt state change, and the new returned string will replace the previously rendered one. The prompt cursor appears after the string. + +Wrapping the rendering function with `createPrompt()` will setup the rendering layer, inject the state management utilities, and wait until the `done` callback is called. + +```ts +import { createPrompt } from '@inquirer/core'; + +const input = createPrompt((config, done) => { + // Implement logic + + return '? My question'; +}); + +// And it is then called as +const answer = await input({ + /* config */ +}); +``` + +## Hooks + +State management and user interactions are handled through hooks. Hooks are common [within the React ecosystem](https://react.dev/reference/react/hooks), and Inquirer reimplement the common ones. + +### State hook + +State lets a component “remember” information like user input. For example, an input prompt can use state to store the input value, while a list prompt can use state to track the cursor index. + +`useState` declares a state variable that you can update directly. + +```ts +import { createPrompt, useState } from '@inquirer/core'; + +const input = createPrompt((config, done) => { + const [index, setIndex] = useState(0); + + // ... +``` + +### Keypress hook + +Almost all prompts need to react to user actions. In a terminal, this is done through typing. + +`useKeypress` allows you to react to keypress events, and access the prompt line. + +```ts +const input = createPrompt((config, done) => { + useKeypress((key) => { + if (key.name === 'enter') { + done(answer); + } + }); + + // ... +``` + +Behind the scenes, Inquirer prompts are wrappers around [readlines](https://nodejs.org/api/readline.html). Aside the keypress event object, the hook also pass the active readline instance to the event handler. + +```ts +const input = createPrompt((config, done) => { + useKeypress((key, readline) => { + setValue(readline.line); + }); + + // ... +``` + +### Ref hook + +Refs let a prompt hold some information that isn’t used for rendering, like a class instance or a timeout ID. Unlike with state, updating a ref does not re-render your prompt. Refs are an “escape hatch” from the rendering paradigm. + +`useRef` declares a ref. You can hold any value in it, but most often it’s used to hold a timeout ID. + +```ts +const input = createPrompt((config, done) => { + const timeout = useRef(null); + + // ... +``` + +### Effect Hook + +Effects let a prompt connect to and synchronize with external systems. This includes dealing with network or animations. + +`useEffect` connects a component to an external system. + +```ts +const chat = createPrompt((config, done) => { + useEffect(() => { + const connection = createConnection(roomId); + connection.connect(); + return () => connection.disconnect(); + }, [roomId]); + + // ... +``` + +### Performance hook + +A common way to optimize re-rendering performance is to skip unnecessary work. For example, you can tell Inquirer to reuse a cached calculation or to skip a re-render if the data has not changed since the previous render. + +`useMemo` lets you cache the result of an expensive calculation. + +```ts +const todoSelect = createPrompt((config, done) => { + const visibleTodos = useMemo(() => filterTodos(todos, tab), [todos, tab]); + + // ... +``` + +### Rendering hooks + +#### Prefix / loading + +All default prompts, and most custom ones, uses a prefix at the beginning of the prompt line. This helps visually delineate different questions, and provides a convenient area to render a loading spinner. + +`usePrefix` is a built-in hook to do this. + +```ts +const input = createPrompt((config, done) => { + const prefix = usePrefix({ status }); + + return `${prefix} My question`; +}); +``` + +#### Pagination + +When looping through a long list of options (like in the `select` prompt), paginating the results appearing on the screen at once can be necessary. The `usePagination` hook is the utility used within the `select` and `checkbox` prompts to cycle through the list of options. + +Pagination works by taking in the list of options and returning a subset of the rendered items that fit within the page. The hook takes in a few options. It needs a list of options (`items`), and a `pageSize` which is the number of lines to be rendered. The `active` index is the index of the currently selected/selectable item. The `loop` option is a boolean that indicates if the list should loop around when reaching the end: this is the default behavior. The pagination hook renders items only as necessary, so it takes a function that can render an item at an index, including an `active` state, called `renderItem`. + +```js +export default createPrompt((config, done) => { + const [active, setActive] = useState(0); + + const allChoices = config.choices.map((choice) => choice.name); + + const page = usePagination({ + items: allChoices, + active: active, + renderItem: ({ item, index, isActive }) => `${isActive ? ">" : " "}${index}. ${item.toString()}` + pageSize: config.pageSize, + loop: config.loop, + }); + + return `... ${page}`; +}); +``` + +## `createPrompt()` API + +As we saw earlier, the rendering function should return a string, and eventually call `done` to close the prompt and return the answer. + +```ts +const input = createPrompt((config, done) => { + const [value, setValue] = useState(); + + useKeypress((key, readline) => { + if (key.name === 'enter') { + done(answer); + } else { + setValue(readline.line); + } + }); + + return `? ${config.message} ${value}`; +}); +``` + +The rendering function can also return a tuple of 2 string (`[string, string]`.) The first string represents the prompt. The second one is content to render under the prompt, like an error message. The text input cursor will appear after the first string. + +```ts +const number = createPrompt((config, done) => { + // Add some logic here + + return [`? My question ${input}`, `! The input must be a number`]; +}); +``` + +### Typescript + +If using typescript, `createPrompt` takes 2 generic arguments. + +```ts +// createPrompt +const input = createPrompt(// ... +``` + +The first one is the type of the resolved value + +```ts +const answer: string = await input(); +``` + +The second one is the type of the prompt config; in other words the interface the created prompt will provide to users. + +```ts +const answer = await input({ + message: 'My question', +}); +``` + +## Key utilities + +Listening for keypress events inside an inquirer prompt is a very common pattern. To ease this, we export a few utility functions taking in the keypress event object and return a boolean: + +- `isEnterKey()` +- `isBackspaceKey()` +- `isSpaceKey()` +- `isUpKey()` - Note: this utility will handle vim and emacs keybindings (up, `k`, and `ctrl+p`) +- `isDownKey()` - Note: this utility will handle vim and emacs keybindings (down, `j`, and `ctrl+n`) +- `isNumberKey()` one of 1, 2, 3, 4, 5, 6, 7, 8, 9, 0 + +## Theming + +Theming utilities will allow you to expose customization of the prompt style.

We test for both standard and non-standard codes, as most of them follow the same or similar format and can be safely matched in strings without the risk of removing actual string content. There are a few non-standard control codes that do not follow the traditional format (i.e. they end in numbers) thus forcing us to exclude them from the test because we cannot reliably match them. + +On the historical side, those ECMA standards were established in the early 90's whereas the VT100, for example, was designed in the mid/late 70's. At that point in time, control codes were still pretty ungoverned and engineers used them for a multitude of things, namely to activate hardware ports that may have been proprietary. Somewhere else you see a similar 'anarchy' of codes is in the x86 architecture for processors; there are a ton of "interrupts" that can mean different things on certain brands of processors, most of which have been phased out. + + +## Maintainers + +- [Sindre Sorhus](https://github.com/sindresorhus) +- [Josh Junon](https://github.com/qix-) + + +--- + +

These pipes have + * limited (and platform-specific) capacity. If the subprocess writes to + * stdout in excess of that limit without the output being captured, the + * subprocess blocks waiting for the pipe buffer to accept more data. This is + * identical to the behavior of pipes in the shell. Use the `{ stdio: 'ignore' }` option if the output will not be consumed. + * + * The command lookup is performed using the `options.env.PATH` environment + * variable if `env` is in the `options` object.

If `options.env` is set without `PATH`, lookup on Unix is performed + * on a default search path search of `/usr/bin:/bin` (see your operating system's + * manual for execvpe/execvp), on Windows the current processes environment + * variable `PATH` is used. + * + * On Windows, environment variables are case-insensitive. Node.js + * lexicographically sorts the `env` keys and uses the first one that + * case-insensitively matches. Only first (in lexicographic order) entry will be + * passed to the subprocess.

The resulting + * message might not be the same as what is originally sent. + * + * For example, in the parent script: + * + * ```js + * import cp from 'node:child_process'; + * const n = cp.fork(`${__dirname}/sub.js`); + * + * n.on('message', (m) => { + * console.log('PARENT got message:', m); + * }); + * + * // Causes the child to print: CHILD got message: { hello: 'world' } + * n.send({ hello: 'world' }); + * ``` + * + * And then the child script, `'sub.js'` might look like this: + * + * ```js + * process.on('message', (m) => { + * console.log('CHILD got message:', m); + * }); + * + * // Causes the parent to print: PARENT got message: { foo: 'bar', baz: null } + * process.send({ foo: 'bar', baz: NaN }); + * ``` + * + * Child Node.js processes will have a `process.send()` method of their own + * that allows the child to send messages back to the parent. + * + * There is a special case when sending a `{cmd: 'NODE_foo'}` message. Messages + * containing a `NODE_` prefix in the `cmd` property are reserved for use within + * Node.js core and will not be emitted in the child's `'message'` event. Rather, such messages are emitted using the `'internalMessage'` event and are consumed internally by Node.js. + * Applications should avoid using such messages or listening for `'internalMessage'` events as it is subject to change without notice. + * + * The optional `sendHandle` argument that may be passed to `subprocess.send()` is + * for passing a TCP server or socket object to the child process. The child will + * receive the object as the second argument passed to the callback function + * registered on the `'message'` event. Any data that is received and buffered in + * the socket will not be sent to the child. Sending IPC sockets is not supported on Windows. + * + * The optional `callback` is a function that is invoked after the message is + * sent but before the child may have received it. The function is called with a + * single argument: `null` on success, or an `Error` object on failure. + * + * If no `callback` function is provided and the message cannot be sent, an `'error'` event will be emitted by the `ChildProcess` object. This can + * happen, for instance, when the child process has already exited. + * + * `subprocess.send()` will return `false` if the channel has closed or when the + * backlog of unsent messages exceeds a threshold that makes it unwise to send + * more. Otherwise, the method returns `true`. The `callback` function can be + * used to implement flow control. + * + * #### Example: sending a server object + * + * The `sendHandle` argument can be used, for instance, to pass the handle of + * a TCP server object to the child process as illustrated in the example below: + * + * ```js + * import { createServer } from 'node:net'; + * import { fork } from 'node:child_process'; + * const subprocess = fork('subprocess.js'); + * + * // Open up the server object and send the handle. + * const server = createServer(); + * server.on('connection', (socket) => { + * socket.end('handled by parent'); + * }); + * server.listen(1337, () => { + * subprocess.send('server', server); + * }); + * ``` + * + * The child would then receive the server object as: + * + * ```js + * process.on('message', (m, server) => { + * if (m === 'server') { + * server.on('connection', (socket) => { + * socket.end('handled by child'); + * }); + * } + * }); + * ``` + * + * Once the server is now shared between the parent and child, some connections + * can be handled by the parent and some by the child. + * + * While the example above uses a server created using the `node:net` module, `node:dgram` module servers use exactly the same workflow with the exceptions of + * listening on a `'message'` event instead of `'connection'` and using `server.bind()` instead of `server.listen()`. This is, however, only + * supported on Unix platforms. + * + * #### Example: sending a socket object + * + * Similarly, the `sendHandler` argument can be used to pass the handle of a + * socket to the child process. The example below spawns two children that each + * handle connections with "normal" or "special" priority: + * + * ```js + * import { createServer } from 'node:net'; + * import { fork } from 'node:child_process'; + * const normal = fork('subprocess.js', ['normal']); + * const special = fork('subprocess.js', ['special']); + * + * // Open up the server and send sockets to child. Use pauseOnConnect to prevent + * // the sockets from being read before they are sent to the child process. + * const server = createServer({ pauseOnConnect: true }); + * server.on('connection', (socket) => { + * + * // If this is special priority... + * if (socket.remoteAddress === '74.125.127.100') { + * special.send('socket', socket); + * return; + * } + * // This is normal priority. + * normal.send('socket', socket); + * }); + * server.listen(1337); + * ``` + * + * The `subprocess.js` would receive the socket handle as the second argument + * passed to the event callback function: + * + * ```js + * process.on('message', (m, socket) => { + * if (m === 'socket') { + * if (socket) { + * // Check that the client socket exists. + * // It is possible for the socket to be closed between the time it is + * // sent and the time it is received in the child process. + * socket.end(`Request handled with ${process.argv[2]} priority`); + * } + * } + * }); + * ``` + * + * Do not use `.maxConnections` on a socket that has been passed to a subprocess. + * The parent cannot track when the socket is destroyed. + * + * Any `'message'` handlers in the subprocess should verify that `socket` exists, + * as the connection may have been closed during the time it takes to send the + * connection to the child. + * @since v0.5.9 + * @param sendHandle `undefined`, or a [`net.Socket`](https://nodejs.org/docs/latest-v24.x/api/net.html#class-netsocket), [`net.Server`](https://nodejs.org/docs/latest-v24.x/api/net.html#class-netserver), or [`dgram.Socket`](https://nodejs.org/docs/latest-v24.x/api/dgram.html#class-dgramsocket) object. + * @param options The `options` argument, if present, is an object used to parameterize the sending of certain types of handles. `options` supports the following properties: + */ + send(message: Serializable, callback?: (error: Error | null) => void): boolean; + send(message: Serializable, sendHandle?: SendHandle, callback?: (error: Error | null) => void): boolean; + send( + message: Serializable, + sendHandle?: SendHandle, + options?: MessageOptions, + callback?: (error: Error | null) => void, + ): boolean; + /** + * Closes the IPC channel between parent and child, allowing the child to exit + * gracefully once there are no other connections keeping it alive.

If one needs to + * upload a file with a POST request, then write to the `ClientRequest` object. + * + * ```js + * import http from 'node:http'; + * import { Buffer } from 'node:buffer'; + * + * const postData = JSON.stringify({ + * 'msg': 'Hello World!', + * }); + * + * const options = { + * hostname: 'www.google.com', + * port: 80, + * path: '/upload', + * method: 'POST', + * headers: { + * 'Content-Type': 'application/json', + * 'Content-Length': Buffer.byteLength(postData), + * }, + * }; + * + * const req = http.request(options, (res) => { + * console.log(`STATUS: ${res.statusCode}`); + * console.log(`HEADERS: ${JSON.stringify(res.headers)}`); + * res.setEncoding('utf8'); + * res.on('data', (chunk) => { + * console.log(`BODY: ${chunk}`); + * }); + * res.on('end', () => { + * console.log('No more data in response.'); + * }); + * }); + * + * req.on('error', (e) => { + * console.error(`problem with request: ${e.message}`); + * }); + * + * // Write data to request body + * req.write(postData); + * req.end(); + * ``` + * + * In the example `req.end()` was called. With `http.request()` one + * must always call `req.end()` to signify the end of the request - + * even if there is no data being written to the request body. + * + * If any error is encountered during the request (be that with DNS resolution, + * TCP level errors, or actual HTTP parse errors) an `'error'` event is emitted + * on the returned request object. As with all `'error'` events, if no listeners + * are registered the error will be thrown. + * + * There are a few special headers that should be noted. + * + * * Sending a 'Connection: keep-alive' will notify Node.js that the connection to + * the server should be persisted until the next request. + * * Sending a 'Content-Length' header will disable the default chunked encoding. + * * Sending an 'Expect' header will immediately send the request headers. + * Usually, when sending 'Expect: 100-continue', both a timeout and a listener + * for the `'continue'` event should be set.

If `async` / `await` flow and speed are both essential, a mixed approach can be applied: + * + * ```js + * import { once } from 'node:events'; + * import { createReadStream } from 'node:fs'; + * import { createInterface } from 'node:readline'; + * + * (async function processLineByLine() { + * try { + * const rl = createInterface({ + * input: createReadStream('big-file.txt'), + * crlfDelay: Infinity, + * }); + * + * rl.on('line', (line) => { + * // Process the line. + * }); + * + * await once(rl, 'close'); + * + * console.log('File processed.'); + * } catch (err) { + * console.error(err); + * } + * })(); + * ``` + * @since v0.7.7 + */ + export function emitKeypressEvents(stream: NodeJS.ReadableStream, readlineInterface?: Interface): void; + export type Direction = -1 | 0 | 1; + export interface CursorPos { + rows: number; + cols: number; + } + /** + * The `readline.clearLine()` method clears current line of given [TTY](https://nodejs.org/docs/latest-v24.x/api/tty.html) stream + * in a specified direction identified by `dir`. + * @since v0.7.7 + * @param callback Invoked once the operation completes. + * @return `false` if `stream` wishes for the calling code to wait for the `'drain'` event to be emitted before continuing to write additional data; otherwise `true`. + */ + export function clearLine(stream: NodeJS.WritableStream, dir: Direction, callback?: () => void): boolean; + /** + * The `readline.clearScreenDown()` method clears the given [TTY](https://nodejs.org/docs/latest-v24.x/api/tty.html) stream from + * the current position of the cursor down. + * @since v0.7.7 + * @param callback Invoked once the operation completes. + * @return `false` if `stream` wishes for the calling code to wait for the `'drain'` event to be emitted before continuing to write additional data; otherwise `true`. + */ + export function clearScreenDown(stream: NodeJS.WritableStream, callback?: () => void): boolean; + /** + * The `readline.cursorTo()` method moves cursor to the specified position in a + * given [TTY](https://nodejs.org/docs/latest-v24.x/api/tty.html) `stream`. + * @since v0.7.7 + * @param callback Invoked once the operation completes. + * @return `false` if `stream` wishes for the calling code to wait for the `'drain'` event to be emitted before continuing to write additional data; otherwise `true`. + */ + export function cursorTo(stream: NodeJS.WritableStream, x: number, y?: number, callback?: () => void): boolean; + /** + * The `readline.moveCursor()` method moves the cursor _relative_ to its current + * position in a given [TTY](https://nodejs.org/docs/latest-v24.x/api/tty.html) `stream`. + * @since v0.7.7 + * @param callback Invoked once the operation completes. + * @return `false` if `stream` wishes for the calling code to wait for the `'drain'` event to be emitted before continuing to write additional data; otherwise `true`. + */ + export function moveCursor(stream: NodeJS.WritableStream, dx: number, dy: number, callback?: () => void): boolean; +} +declare module "node:readline" { + export * from "readline"; +} diff --git a/node_modules/@types/mute-stream/node_modules/@types/node/readline/promises.d.ts b/node_modules/@types/mute-stream/node_modules/@types/node/readline/promises.d.ts new file mode 100644 index 00000000..c0ebf4ba --- /dev/null +++ b/node_modules/@types/mute-stream/node_modules/@types/node/readline/promises.d.ts @@ -0,0 +1,161 @@ +/** + * @since v17.0.0 + */ +declare module "readline/promises" { + import { Abortable } from "node:events"; + import { + CompleterResult, + Direction, + Interface as _Interface, + ReadLineOptions as _ReadLineOptions, + } from "node:readline"; + /** + * Instances of the `readlinePromises.Interface` class are constructed using the `readlinePromises.createInterface()` method.

Create a configuration file building a blob that can be injected into the + * single executable application (see `Generating single executable preparation blobs` for details): + * ```bash + * echo '{ "main": "hello.js", "output": "sea-prep.blob" }' > sea-config.json + * ``` + * 3. Generate the blob to be injected: + * ```bash + * node --experimental-sea-config sea-config.json + * ``` + * 4. Create a copy of the `node` executable and name it according to your needs: + * * On systems other than Windows: + * ```bash + * cp $(command -v node) hello + * ``` + * * On Windows: + * ```text + * node -e "require('fs').copyFileSync(process.execPath, 'hello.exe')" + * ``` + * The `.exe` extension is necessary. + * 5. Remove the signature of the binary (macOS and Windows only): + * * On macOS: + * ```bash + * codesign --remove-signature hello + * ``` + * * On Windows (optional): + * [signtool](https://learn.microsoft.com/en-us/windows/win32/seccrypto/signtool) can be used from the installed [Windows SDK](https://developer.microsoft.com/en-us/windows/downloads/windows-sdk/). + * If this step is + * skipped, ignore any signature-related warning from postject. + * ```powershell + * signtool remove /s hello.exe + * ``` + * 6. Inject the blob into the copied binary by running `postject` with + * the following options: + * * `hello` / `hello.exe` \- The name of the copy of the `node` executable + * created in step 4. + * * `NODE_SEA_BLOB` \- The name of the resource / note / section in the binary + * where the contents of the blob will be stored. + * * `sea-prep.blob` \- The name of the blob created in step 1. + * * `--sentinel-fuse NODE_SEA_FUSE_fce680ab2cc467b6e072b8b5df1996b2` \- The [fuse](https://www.electronjs.org/docs/latest/tutorial/fuses) used by the Node.js project to detect if a file has been + * injected. + * * `--macho-segment-name NODE_SEA` (only needed on macOS) - The name of the + * segment in the binary where the contents of the blob will be + * stored. + * To summarize, here is the required command for each platform: + * * On Linux: + * ```bash + * npx postject hello NODE_SEA_BLOB sea-prep.blob \ + * --sentinel-fuse NODE_SEA_FUSE_fce680ab2cc467b6e072b8b5df1996b2 + * ``` + * * On Windows - PowerShell: + * ```powershell + * npx postject hello.exe NODE_SEA_BLOB sea-prep.blob ` + * --sentinel-fuse NODE_SEA_FUSE_fce680ab2cc467b6e072b8b5df1996b2 + * ``` + * * On Windows - Command Prompt: + * ```text + * npx postject hello.exe NODE_SEA_BLOB sea-prep.blob ^ + * --sentinel-fuse NODE_SEA_FUSE_fce680ab2cc467b6e072b8b5df1996b2 + * ``` + * * On macOS: + * ```bash + * npx postject hello NODE_SEA_BLOB sea-prep.blob \ + * --sentinel-fuse NODE_SEA_FUSE_fce680ab2cc467b6e072b8b5df1996b2 \ + * --macho-segment-name NODE_SEA + * ``` + * 7. Sign the binary (macOS and Windows only): + * * On macOS: + * ```bash + * codesign --sign - hello + * ``` + * * On Windows (optional): + * A certificate needs to be present for this to work. However, the unsigned + * binary would still be runnable. + * ```powershell + * signtool sign /fd SHA256 hello.exe + * ``` + * 8.
