feat: add `is` operator for type checking and refactor primitives registration Add TOKEN_IS token and CODE_IS bytecode to support runtime type checking via the `is` keyword. Refactor primitive registration by replacing `registerPrimitives` with `loadCore`, which compiles a core library string to define built-in classes (Bool, Class, Function, Num, Null, String, IO) and then attaches primitive methods to them. Update Primitive typedef to remove unused numArgs parameter, and add findGlobal helper to retrieve globals by name. Include test files for class syntax, class instantiation, and the new `is` operator. 2013-11-08 02:07:32 +01:00			`class Foo {}`

feat: replace `new` keyword with `this` constructor syntax and `ClassName.new()` calls across core library and docs Replace all uses of the `new` reserved word with explicit `this new()` constructor definitions and `ClassName.new()` instantiation calls in builtin/core.wren. Update all documentation files (classes.markdown, fiber.markdown, fn.markdown, sequence.markdown, error-handling.markdown, expressions.markdown, fibers.markdown, functions.markdown) to reflect the new constructor syntax, removing `new` keyword examples and replacing them with `ClassName.new()` patterns and `this new()` definitions. 2015-07-10 18:18:22 +02:00			`var foo = Foo.new()`
feat: rename IO.write to IO.print and add Unicode escape support in strings Rename the IO.write method to IO.print, which now prints without a trailing newline, and add a new IO.print method that appends a newline after output. Update all benchmark, example, and test files to use IO.print instead of IO.write. Additionally, implement Unicode escape sequence parsing in the compiler's string tokenizer, supporting \uXXXX and \u{...} syntax with proper UTF-8 encoding for code points up to U+10FFFF. 2014-01-05 21:27:12 +01:00			`IO.print(foo is Foo) // expect: true`
refactor: replace `Foo.new` constructor syntax with `new Foo` and simplify superclass constructor calls Remove the `this new` constructor declaration syntax in favor of a `new` keyword that creates instances directly. Superclass constructors are now invoked via bare `super(args)` instead of `super.new(args)`, eliminating the semantic weirdness of calling a constructor on a partially-constructed instance. Update the compiler to treat `new` as a keyword token, replace the `isMethod` flag with `methodName`/`methodLength` fields, and change the VM's `NEW` opcode to pop the class from the stack before creating the instance. Add a default `new` native method on Object that returns `this`. Update all benchmarks and tests to use the new syntax. 2013-12-19 16:02:27 +01:00
