Directory Separator Constant

[dragonflyeye]

Other platforms I've used define a Directory Separator (/ or \, based on platform) in their configuration files so that developers don't have to try to write parallel code for different platforms. It doesn't appear WordPress actually uses this, but it seems like a simple thing to include into the wp-config.php file.

Patch file of wp-config-sample.php with new definition.

Just defining a constant without using it in Core is pointless.

More so, PHP already comes with DIRECTORY_SEPARATOR, which has been suggested before: #15598

Well, using it in the core would be the point, wouldn't it? Didn't realize I'd have to create a patch with every single change across the entire system in it.

As for DIRECTORY_SEPARATOR, that's all well and good, but even the basic wp-config.php file doesn't make use of it, as in this:
define('ABSPATH', dirname(FILE) . '/');

There's no need. Windows works fine. DIRECTORY_SEPARATOR is much better for say, exploding a path received from Windows. And sometimes we do take that into account when working off __FILE__, see plugin_basename() for example. But building paths don't require that at all.
