Hmm... we could have employed Pathname, couldn't we?

It does not represent the file itself. A Pathname can be relative or absolute. It’s not until you try to reference the file that it even matters whether the file exists or not.

[arlimus]

@srenatus basename for Pathname defaults to the running system's separator. When we are targeting a remote system, that might be local=Unix vs remote=Windows. Afaics, pathname doesn't provide us with a configurable separator. The docs point from Pathname.basename to File.basename:

See File.basename. Returns the last component of the path.

which in turn:

Returns the last component of the filename given in file_name, which can be formed using both File::SEPARATOR and File::ALT_SEPARATOR as the separator when File::ALT_SEPARATOR is not nil. If suffix is given and present at the end of file_name, it is removed. If suffix is “.*”, any extension will be removed.

Try:

Pathname.new('C:\hello\world').basename

Unless you know how to do that?

[srenatus]

Nah, you're right. I mistook the "suffix" thing for the ability to pass a separator :/

Can't even get Pathname to work when I override File::SEPARATOR...

[arlimus]

Oh wow, I was expecting it to work at least that far... well, really hate to duplicate code, but ... 🐹
