Add tab-completion support to the interactive REPL by introducing a new `Meta.getModuleVariables` foreign method that returns all top-level variable names from a given module. The REPL's `run()` method now handles the tab key to append completions, and the `refreshLine` method accepts a boolean parameter to control whether completion hints are shown. Also fix the Ctrl-D exit logic (inverted condition) and remove the unused `EscapeBracket` class.
This contains the automated validation suite for the VM and built-in libraries.
-
benchmark/- Performance tests. These aren't strictly pass/fail, but let us compare performance both against other languages and against previous builds of Wren itself. -
core/- Tests for the built in core library, mainly methods on the core classes. If a bug is inwren_core.corwren_value.c, it will most likely break one of these tests. -
language/- Tests of the language itself, its grammar and runtime semantics. If a bug is inwren_compiler.corwren_vm.c, it will most likely break one of these tests. This includes tests for the syntax for the literal forms of the core classes. -
limit/- Tests for various hardcoded limits. The language doesn't officially specify these limits, but the Wren implementation has them. These tests ensure that limit behavior is well-defined and tested.
