Roger Pack

5/28/2009 1:39:00 PM

currently on windows we've got:

>> File.expand_path '~'
=> "/Documents and Settings/Melissa.BLACKY"

shouldn't it be
>> File.expand_path '~'
=> "c:/Documents and Settings/Melissa.BLACKY"

?

What's your Ruby version?
In my test, it works as expected:

C:\>ruby -ve 'p File.expand_path("~")'
ruby 1.9.1p0 (2009-01-30 revision 21907) [i386-mswin32]
"C:/Documents and Settings/phasis"

Odd:

D:\dev>c:ruby -ve 'p File.expand_path("~")'
ruby 1.9.1p129 (2009-05-12 revision 23412) [i386-mingw32]
"/Documents and Settings/Melissa.BLACKY"

maybe I should try p0 again :)
My guess is it's some compiler define not set right.

What's your ENV['HOME'], ENV['HOMEDRIVE'] and ENV['USERPROFILE'] set to?

Does it work if you try it from C:\ on the command line instead of D:\ ?

Odd. Works great on one computer of mine and on the other (which has
HOME HOMEDRIVE AND USERPROFILE all set) it doesn't. Any version of
ruby.
Odd. Well I'm glad to know that by default it includes the drive
letter, which is right. Luis if you're reading this might explain the
weird gem installation to different drives issue.
Thanks for your help all.
