feat: replace AST-based parser with single-pass bytecode compiler and VM Replace the recursive-descent parser that built an AST (Node* tree) with a single-pass compiler that emits bytecode directly into a Block structure. Remove the parser.c/parser.h files and their AST node types (NodeLiteral, NodeCall, NodeBinaryOp, etc.), add new compiler.c/compiler.h with a Compiler struct and Pratt-style precedence parsing that outputs CODE_CONSTANT and CODE_END instructions, and introduce vm.c/vm.h containing a Fiber-based interpreter with a stack, interpret() loop, and printValue() for OBJ_INT. Update main.c to call compile() then interpret() instead of parse(), remove TOKEN_INDENT/TOKEN_OUTDENT from token.h and dumpTokens(), and adjust the Xcode project to include the new source files while excluding the old parser. 2013-10-22 21:16:39 +02:00			`#ifndef wren_parser_h`

feat: add class parsing and object type system with ObjBlock, ObjClass, and ObjNum structs Introduce token types TOKEN_CLASS and TOKEN_META for class declaration parsing in the compiler. Refactor the internal object model from a single Obj union to distinct ObjNum, ObjBlock, and ObjClass structs, replacing the old Block type with ObjBlock throughout the compiler, VM, and main entry point. Implement makeClass() and makeBlock() factory functions, update makeNum() to return ObjNum*, and add CODE_CLASS and CODE_DUP bytecodes to support class definition at compile time. Modify the symbol table and method dispatch to use a Method union (primitive or block) stored in ObjClass, and update the VM's callBlock signature and newVM initialization accordingly. 2013-10-24 07:50:04 +02:00			`ObjBlock* compile(VM* vm, const char* source, size_t sourceLength);`
