This is a bit of a style preference since of course you can always write the same thing with a for loop. However, I think sometimes the code looks better when using this method. It also provides an alternative to Sequence.map for cases where you don't need the resulting list, and one that becomes especially necessary when Sequence.map is changed to return a new sequence. The example in the README.md file was using Sequence.map in a way that required this alternative in that case.
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. -
io/- Tests for the built in IO library. In other words, methods on theIOclass. If a bug is inwren_io.c, it should 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.
