feat: add module loading with String.import_ and embedder-provided loadModuleFn Implement initial module system allowing Wren code to import other modules via a temporary `String.import_` method. The embedder must supply a `WrenLoadModuleFn` callback that returns source code for a given module name; the VM caches loaded modules and returns a fiber to execute the module body. Add `wrenImportModule` to the VM API, wire `loadModuleFn` into `WrenConfiguration`, and update the CLI interpreter to resolve imports relative to the entry script's directory. Include test cases for importing multiple variables, shared imports across modules, and verifying that variable bindings are independent across import sites. 2015-02-06 16:01:15 +01:00			`// nontest`
			`IO.print("a")`
feat: append ".wren" extension to module paths in readModule and update test imports The readModule function now concatenates ".wren" to the module path when constructing the full file path, increasing the path buffer by 5 bytes. All test files have been updated to use bare module names (without ".wren") in import_ calls, and the expected error messages in unknown_module and unknown_variable tests are adjusted accordingly. A trailing blank line is also removed from wren_vm.c. 2015-02-06 20:52:05 +01:00			`var Shared = "shared".import_("Shared")`
