Subject: Strange Win32 ARGV problem

(reposting in plain text...)


Using the following one line ruby script (to dump out argv):
puts "ARGV:\n#{ARGV.join("\n")}\n---"
I'm seeing VERY strange behavior with Ruby 1.8.0:

First, I'll show that 4 different files exist in a local directory.

M:\builds\SYStest\eic\Yellow\products\EIC\src\attendant>dir
audiodetaildlg.*
 Volume in drive M is WorkDrive3
 Volume Serial Number is 90DB-A0F3

 Directory of M:\builds\SYStest\eic\Yellow\products\EIC\src\attendant

09/04/2002  03:15 PM             3,817 AudioDetailDlg.cpp
03/25/2003  05:00 PM             1,498 AudioDetailDlg.h
               2 File(s)          5,315 bytes
               0 Dir(s)   6,820,958,208 bytes free

M:\builds\SYStest\eic\Yellow\products\EIC\src\attendant>dir audionode.*
 Volume in drive M is WorkDrive3
 Volume Serial Number is 90DB-A0F3

 Directory of M:\builds\SYStest\eic\Yellow\products\EIC\src\attendant

08/01/2002  02:25 PM             3,409 AudioNode.cpp
07/31/2002  04:07 PM             1,849 AudioNode.h
               2 File(s)          5,258 bytes
               0 Dir(s)   6,820,958,208 bytes free

Now, I'll run the script that dumps out argv and pass it some wildcard
arguments which should match these files.

M:\builds\SYStest\eic\Yellow\products\EIC\src\attendant>ruby bs.rb test
AudioDetailDlg.* AudioNode.*
ARGV:
test
AudioDetailDlg.* AudioNode.*
---

Huh?  Why did the two arguments get passed in as one argument to argv !?
This is causing some of my scripts serious problems.  :(

M:\builds\SYStest\eic\Yellow\products\EIC\src\attendant>ruby bs.rb test
AudioDetailDlg.*
ARGV:
test
AudioDetailDlg.cpp
AudioDetailDlg.h
---
Hmmm.... now it performed wildcard expansion and put the two files as
separate arguments.
Basically, the first option after a wildcard argument gets grouped in
with that wildcard parameter as a single argument and the expansion
doesn't occur.

M:\builds\SYStest\eic\Yellow\products\EIC\src\attendant>ruby bs.rb test
AudioDetailDlg.* foo AudioNode.*
ARGV:
test
AudioDetailDlg.* foo
AudioNode.cpp
AudioNode.h
---
