Several Improvements (well... see description)

[hybras]

I forked your project and made a bunch of changes. So far I've

• created os specific modules
• changed how cfg(target_os) was being used
• Made the unix variant use which to check for the different open handlers.

I also plan to change the windows variant to call to explorer.exe using Command instead of winapi::um::shellapi::ShellExecuteW. This removes unsafe from windows::that and drastically simplifies the method.

I would like your feedback on my changes.

Whether you accept them or not, I love open! Previously I was using a shell function, which was very hacky not always portable.

question: isn't xdg-open always available?

question: isn't xdg-open always available?

You... are probably right. But by that logic, why are we checking for alternatives at all? Do u want me to special case xdg-open?

EDIT: On my wsl ubuntu install, xdg-utils is not installed by default.

Will have a closer look later. In the meantime: Maybe also consult the ‘opener’ crate for reference.

Would you be OK to send a draft PR so I can have a look and potentially leave some comments?

[hybras]

Yes I'll do that. At time of writing i still haven't finished the last point I mentioned
