Implement String.split(delim) and String.replace(from, to) methods in the core Wren VM. split returns a list of substrings separated by the given delimiter, while replace returns a new string with all occurrences of the old substring replaced by the new one. Both methods validate arguments (must be non-empty strings) and abort the fiber on invalid input. Include comprehensive test suites covering basic usage, multiple matches, non-ASCII characters, 8-bit clean data, and error cases. Update the string.markdown documentation with usage examples for both methods.
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.
