Change in Dir.glob behavior on Windows between 1.8.5 and 1.8

Ruby

I’ve checked ruby-talk emails regarding Dir.glob and File.join but
didn’t see this one reported before.

C:> ruby --version
ruby 1.8.5 (2006-12-25 patchlevel 12) [i386-mswin32]

C:> irb
irb(main):001:0> Dir.glob(File.join(ENV[‘USERPROFILE’], ‘*.rnd’))
=> [C:\Documents and Settings\yura/putty.rnd"]

C:> ruby --version
ruby 1.8.6 (2007-03-13 patchlevel 0) [i386-mswin32]

C:> irb
irb(main):001:0> Dir.glob(File.join(ENV[‘USERPROFILE’], ‘*.rnd’))
=> []

C:> ruby --version
ruby 1.8.6 (2007-03-13 patchlevel 0) [i386-mswin32]

C:> irb
irb(main):001:0> Dir.glob(File.join(ENV[‘USERPROFILE’], ‘*.rnd’))
=> []

I could reproduce this on my system too.

Could it be that 1.8.6 Dir.glob gets upset on the spaces in
ENV[‘USERPROFILE’]?

No, backslash is a special character.

No, backslash is a special character.

So, is it a “fix” or a “bug”?

What is now a portable way to do the following (does not work on
Windows any more):

Dir.glob(File.join(ENV[‘HOME’], ‘*.dat’))

No, it’s File:ALT_SEPARATOR ():

C:> ruby --version
ruby 1.8.6 (2007-03-13 patchlevel 0) [i386-mswin32]

C:> irb
irb(main):001:0> Dir.glob(File.join(ENV[‘USERPROFILE’],
‘.rnd’).gsub(File::ALT_SEPARATOR, File::SEPARATOR))
=> [C:/Documents and Settings/yura/putty.rnd"]
irb(main):002:0> Dir.glob(File.join(ENV[‘USERPROFILE’],
'.rnd’).gsub(File::SEPARATOR, File::ALT_SEPARATOR))
=> []

a fix.

What is now a portable way to do the following (does not work on
Windows any more):

Dir.glob(File.join(ENV[‘HOME’], ‘*.dat’))

Dir.glob(File.expand_path(’*.dat’, ENV[‘HOME’]))

particularly for ENV[‘HOME’]:

Dir.glob(File.expand_path(’~/*.dat’))
