Claude/wokelang ebnf grammar qoe vv (#20)
* Implement WokeLang interpreter in Rust Complete implementation of WokeLang with: Lexer (src/lexer/): - Token definitions for all keywords, operators, literals - Uses logos for fast tokenization - Handles comments, strings with escapes, numbers Parser (src/parser/): - Recursive descent parser - Full expression parsing with correct precedence - All statement types: remember, when/otherwise, repeat, attempt safely - Pattern matching with decide based on - Emote tags, consent blocks, gratitude declarations AST (src/ast/): - Complete type definitions for all language constructs - Spanned nodes for error reporting Interpreter (src/interpreter/): - Tree-walking interpreter - Scoped environments for variables - Built-in functions: print, len, toString, toInt - Consent system with interactive prompts - Pattern matching evaluation - All operators (arithmetic, comparison, logical) CLI (src/main.rs): - woke <file.woke> - run program - woke --tokenize <file> - show tokens - woke --parse <file> - show AST Examples: - examples/hello.woke - feature showcase - examples/demo.woke - runnable demo * Add REPL, WASM compilation, and Zig FFI REPL (src/repl.rs): - Interactive command-line interface with rustyline - Commands: :help, :quit, :clear, :reset, :load, :ast - Expression evaluation with automatic result printing - Start with `woke` or `woke --repl` WASM Compilation (src/codegen/): - Compile WokeLang to WebAssembly binary format - Uses wasm-encoder for proper WASM generation - Supports functions, expressions, loops, conditionals - Pattern matching compilation - CLI: `woke -c input.woke` outputs input.wasm Zig FFI (src/ffi/, zig/, include/): - C-compatible API for embedding WokeLang - Interpreter lifecycle: woke_interpreter_new/free - Code execution: woke_exec, woke_eval - Value operations: type checking, conversion, creation - Static library (libwokelang.a) and shared library (.so) - C header (include/wokelang.h) - Zig bindings (zig/wokelang.zig) with idiomatic wrapper - Example Zig program and build.zig Other: - examples/math.woke - math functions for WASM demo - Cargo.toml updated for cdylib/staticlib targets * Add comprehensive documentation and wiki Includes: - Project roadmap (ROADMAP.md) with version timeline through v1.0 - Wiki home page with table of contents - Getting Started guides: Installation, Hello World, Basic Syntax, REPL - Language Guide: Functions, Control Flow, Error Handling, Variables/Types - Core Concepts: Consent System, Gratitude, Emote Tags - Reference: CLI, Built-in Functions, Keywords, Operators, Language Spec - Internals: Architecture, Lexer, Parser, Interpreter, WASM, FFI - Tutorial: Building a CLI app * Implement Phase 2 Language Completeness features - Add Result types (Okay/Oops) with pattern matching support - Implement error propagation operator (?) for Result types - Add pattern matching destructuring with guard clauses - Implement module system with use/share keywords - Add new builtins: isOkay, isOops, getOkay, getOops - Update WASM compiler and FFI for new AST variants - Add example programs for Result types and modules * Add static type inference with Hindley-Milner style checker - Implement TypeChecker module with type inference - Support for basic types: Int, Float, String, Bool, Unit - Support for compound types: Array, Result, Maybe, Function - Implement unification algorithm for type constraints - Add built-in function type handling - Include comprehensive test suite for type checking * Implement Phase 3 Worker System with message passing - Add async worker module with thread-based execution - Implement WorkerHandle, WorkerContext, WorkerPool - Add message passing: WorkerMessage enum with Value, Stop, Ping, etc. - Add cancellation tokens for task control - New lexer tokens: send, receive, channel, await, cancel, from - New AST nodes: SendMessage, ReceiveMessage, AwaitWorker, CancelWorker - Update parser for new worker syntax - Update interpreter with worker statement handling - Update WASM codegen and typechecker for new statements - Add worker tests (4 new tests) - Add workers.woke example demonstrating worker system - Update ROADMAP.md with Phase 2 completion status * Implement Phase 3 Security: capability-based security and persistent consent storage - Add CapabilityRegistry with support for FileRead, FileWrite, Execute, Network, Environment, Process, SystemInfo, Crypto, Clipboard, Notify capabilities - Implement wildcard capability matching (e.g., file:read:* grants all file reads) - Add audit logging for all capability requests, grants, denials, and revocations - Create ConsentStore for persistent storage of consent decisions - Support consent durations: Session, Day, Week, Forever, Once - Add security.woke example demonstrating superpower declarations * Implement Phase 4 Standard Library for WokeLang Add comprehensive standard library with the following modules: - std.math: Mathematical functions (abs, sqrt, pow, sin, cos, tan, floor, ceil, round, min, max, random, pi, e) - std.io: File I/O with consent-based access control (readFile, writeFile, appendFile, exists, delete, listDir, createDir, readLine) - std.json: JSON parsing and generation (parse, stringify, get, set) - std.time: Date/time handling (now, timestamp, format, parse, sleep, elapsed) - std.net: HTTP networking with consent (httpGet, httpPost, download) Key features: - StdlibRegistry for function registration and lookup - Capability-based security integration for I/O and network operations - Simple JSON parser/serializer without external dependencies - Basic HTTP client using TCP sockets (no TLS for now) - Elapsed timer with thread-local storage - Add Record variant to Value for JSON objects Includes stdlib_demo.woke example demonstrating all modules. * Implement Phase 5: Bytecode Compiler and VM with Optimizations Add a complete bytecode virtual machine for WokeLang with: Bytecode Infrastructure: - Stack-based OpCode instruction set (arithmetic, control flow, functions) - CompiledFunction with constant pool and local variable slots - CompiledProgram with function registry and entry point detection Bytecode Compiler: - Compiles AST to bytecode instructions - Handles all statement types (VarDecl, Assignment, Conditional, Loop, etc.) - Pattern matching compilation for decide statements - Function call and closure support - Result type (Okay/Oops) compilation Virtual Machine: - Stack-based execution with call frames - Local and global variable support - Full arithmetic and comparison operations - Control flow (jumps, conditionals, loops) - Array and record operations - Result type handling with error propagation - Safety limits (max stack size, max call depth) Optimizer: - Constant folding (evaluates constant expressions at compile time) - Dead code elimination (removes unreachable instructions) - Peephole optimizations (double negation, jump-to-next removal) - Nop removal with jump target patching Performance Benchmarks: - Comparative benchmarks for interpreter vs VM execution - Shows 6-11x speedup with precompiled bytecode * Add EBNF grammar and standard library structure EBNF Grammar (docs/grammar.ebnf): - Complete lexical grammar (literals, identifiers, operators) - Full syntactic grammar for all language constructs - Program structure, functions, statements, expressions - Pattern matching, concurrency, modules, types - Consent blocks, gratitude declarations, pragmas - Emote tags and emotional annotations - Operator precedence documentation Standard Library Structure: lib/common/ - Language-agnostic utilities: - prelude.woke: Core utilities (identity, boolean, numeric, string, array, result) - collections.woke: Higher-order functions (map, filter, reduce, zip, partition) - async.woke: Concurrent patterns (workers, retry, timeout, channels) lib/wokelang/ - WokeLang-specific features: - consent.woke: Consent and permission management with safe operations - emotes.woke: Emotional annotations, sentiment-aware code, code health - gratitude.woke: Attribution management, contributor recognition Includes README documenting library structure and usage patterns. --------- Co-authored-by: Claude <noreply@anthropic.com>
