I request Dir.home again.

previous request was [ruby-dev:31957]

Portable way of getting home directory is complex see [ruby-core:12347].
I think a simplest getting home directory is
Dir.chdir { Dir.pwd }
now.
But this is not thread-safe and changes directory needlessness.

File.expand_path("~") works.

A Dir.home might be more idiomatic considering Windows et al.
(And, of course, File.expand_path "" does not expand to the
home directory in 1.8.6 at least, which may or may not be
expected.)

The changes File.expand_path("~") has not been backported to 1.8.6,
and I believe they will not be.

For that purpose, I always set HOME=%HOMEDRIVE%%HOMEPATH%

Agree on the idiomatic / Ruby style for Dir.home, that will be a nice addition.

What change? Using %HOMEDRIVE%%HOMEPATH%, %USERPROFILE% or the
personal folder patch has been backported at p127, in Jun 2008.

It is not expected definitely. It should be the current
working directory.

Dir.chdir(File.expand_path("~")) works on linux/unix
systems. Does that concept of a "home" Directory translate
to other OS's?

If Dir.chdir without arguments works,
Dir.home can return the directory.
Otherwise Dir.home will raise exception or return nil,
I think.
