Non Existent Method Dir.empty? Description via "ri"

ruby-talk
21

I am using version 0.3.2

Checked it 3 ways

1. irb - non-conclusive

C:\Documents and Settings\Owner>irb
irb(main):001:0> require 'win32/dir'
=> true
irb(main):002:0> Dir::VERSION
(irb):2: warning: toplevel constant VERSION referenced by Dir::VERSION
=> "1.8.6"

2. extra from rdoc on my system

Class Dir
In: lib/win32/dir.rb

Parent: Object

Methods
create_junction empty? junction?
Included Modules
Windows::Directory Windows::Shell Windows::Error Windows::File
Windows::DeviceIO
Constants
VERSION = '0.3.2'

3. gem list

C:\Documents and Settings\Owner>gem query -n win32-dir

*** LOCAL GEMS ***

win32-dir (0.3.2)
    Extra constants and methods for the Dir class on Windows.

It may have been placed in version 0.3.1 but it is not in version
0.3.2

I doubt it:

C:\>irb
irb(main):001:0> require 'win32/dir'
=> true
irb(main):002:0> Dir.empty?('./')
=> false

You're probably using 0.3.0. The Dir.empty? method was added in 0.3.1.
You can check the Dir::VERSION.

Please leave the snideness and nastiness out of it. They add nothing

I didn't mean it as harmful as it obviously sounds. Sorry,

Then take your own advice about thinking first and then writing, friend.

I was really hurt by your code.

Hi,

Sorry Bertram!! I didn't mean to hurt you!

In the last days I had removed a bunch of memory leaks and
documentation bugs of another open source project and the
developers there only charged me not to have obeyed some
formalities. Further I have to cope with a spam flood of
some thousands. That all seems it has been too much; I'm a
bit nervous. Please understand.
