Implement two new C API functions to retrieve list metadata and values from Wren slots: wrenGetSlotListSize returns the element count of a list in a slot, and wrenGetSlotListValue returns a captured WrenValue pointer for a specific index. Add corresponding foreign method bindings in test/api/slots.c and test cases in test/api/slots.wren that verify size retrieval and indexed value access on a three-element list. Also add Damien Radtke to AUTHORS.
This contains the Wren source code. It is organized like so:
-
optional: the Wren and C source code for the optional modules. These are built in to the VM and can be used even when you embed the VM in your own application. But they are also optional and can be compiled out by setting defines. -
cli: the source code for the command line interface. This is a custom executable that embeds the VM in itself. Code here handles reading command-line, running the REPL, loading modules from disc, etc. -
include: the public header directory for the VM. If you are embedding the VM in your own application, you will add this to your include path. -
module: the source code for the built-in modules that come with the CLI. These modules are written in a mixture of C and Wren and generally use libuv to implement their underlying functionality. -
vm: the source code for the Wren VM itself. Unlike code incliandmodule, this has no dependencies on libuv. If you are embedding the VM in your own application from source, you will compile the files here into your app.
