The fpclassify() macro is not available in C++98, causing build failures on older compilers. This commit replaces the switch on fpclassify with explicit isnan() and isinf() checks, handling NaN and infinity edge cases directly. The logic for signed infinity is preserved by comparing value > 0.0 instead of using signbit(), which is also not guaranteed in C++98. This aligns with the existing usage of isnan/isinf elsewhere in the Wren codebase.
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.
