Release: a "which" command written in ruby--very useful for windows users at least

Announcing the release of “ruby which”[1]

README:
Ruby-which is the linux “which” command re-written in ruby [and
windows-friendly].

– An executable locator (which command) for windows that actually
works!

There seems to be a lack of a “which” command for windows that
actually work–they sometimes skip batch files entirely [batch file?
what’s that?] or don’t list extensions, leaving you in doubt. Despite
running “which yyy” you never know what you’re really running when you
next run yyy in the command line–is it yyy.exe or some other yyy.bat
that wasn’t reported by “which”?

Try it–you might really like it.

To install:

C:>gem install rogerdpack-whichr

C:>whichr executable_name_here [extension can be included, but is
optional]

usage:

C:>whichr ruby
higher in the list will be executed first
./ruby.bat
C:/Ruby/bin/ruby.exe
c:/cygwin/bin/ruby.exe

Enjoy.

$ gem which fileutils
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/
1.8/fileutils.rb
$ gem which nokogiri
(checking gem nokogiri-1.3.2 for nokogiri)
/Library/Ruby/Gems/1.8/gems/nokogiri-1.3.2/lib/nokogiri.rb

incidentally, it’s TTY smart:

$ gem which nokogiri | cat
/Library/Ruby/Gems/1.8/gems/nokogiri-1.3.2/lib/nokogiri.rb

$ gem which fileutils
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/fileutils.rb

Nice. I’ve noted the usefulness of “gem which” in the README file now.

Also have updated whichr to v 0.1.2 now to incorporate a few of Alexey
Borzenkov’s suggestions.

ChangeLog:
respect’s ENV[‘PATHEXT’] now on windows
