Dir.exist?

hi!

Wouldn't it be nice to have

   Dir.exist?('somedir')

as an alias for File.directory? It seems quite
understandable that a  
nuby in our
German forum just asked why it wasn't working.

I like it personally - why not consider filing a feature
ticket with 
patch? (I remember seeing many posts here about using the
"alias" macro 
in Ruby .c source which appears simple to do)

Also Socket.exist?, Pipe.exist?, Symlink.exist? and so on?

Yes! If you work with those. Never used them before,
actually.  
Symlinks are not cross-platform.

The point is, not all programmers have the UNIXy view that  
"everything is a file".
For example, when Windows users think about their drive,
they see  
only folders and files.
And it's quite natural to end up with Dir.exists? then.

This proposal focuses on humans, not machines

Yeah, you got me with that. There are no Pipe or Symlink
classes.

I guess it only makes sense for Dir, and maybe for Socket.
Of course, things like Sticky.exists? would be crazy.

I've heard that Windows Vista will have symlinks.  What do
you
expect for it?

# Dir.exist? was added anyway.
