I’m trying to unpack a gem into a particular directory, but cannot get
the --target option to work.
$ gem --version
1.2.0
gem help unpack
Usage: gem unpack GEMNAME [options]
Options:
–target target directory for unpacking
$ gem unpack RedCloth --target /tmp
ERROR: While executing gem … (Gem::CommandLineError)
Too many gem names (RedCloth, /tmp); please specify only one
$ gem unpack RedCloth --target=/tmp
ERROR: While executing gem … (OptionParser::NeedlessArgument)
needless argument: --target=/tmp
How is this supposed to work?
$ gem unpack RedCloth
works fine; trying to give a target not so fine.
Thanks,

gem unpack foo.gem – --target foo # works here.

I just tried it. It “works” by unpacking the gem into the current
directory, completely ignoring the --target option.
Not quite what I’m looking for.

What version of rubygems do you have? Mine cleanly unpacked into the
‘foo’ directory. I’m on 1.2.0.

The – indicates that no more arguments are coming; I suspect it’s a bug
(feature?) in rubygems’s argument parser that it wants it this way.

I’m using 1.2.0, on Kubuntu, running
ruby 1.8.6 (2008-08-08 patchlevel 286) [i686-linux]
I don’t have a ‘foo.gem’ file to try; I have RedCloth installed as a gem
and want to unpack it to a particular location.
I can unpack to the current directory if I omit any --target option.
So, this works:
james@james06:~$ pwd
/home/james
james@james06:~$ gem unpack RedCloth
Unpacked gem: '/home/james/RedCloth-3.0.4'
james@james06:~$
This fails
james@james06:~$ gem unpack RedCloth --target /tmp/RC
ERROR: While executing gem ... (Gem::CommandLineError)
Too many gem names (RedCloth, /tmp/RC); please specify only one
james@james06:~$
Using the extra ‘–’ as in your example acts as if I pass no --target
option:
james@james06:~$ gem unpack RedCloth -- --target /tmp/RC
Unpacked gem: '/home/james/RedCloth-3.0.4'
If I copy the actual gem file to my working directory:
james@james06:~$ gem unpack RedCloth-3.0.4.gem -- --target /tmp/RC
Unpacked gem: '/home/james/RedCloth-3.0.4'
james@james06:~$ gem unpack RedCloth-3.0.4.gem --target /tmp/RC
ERROR: While executing gem ... (Gem::CommandLineError)
Too many gem names (RedCloth-3.0.4.gem, /tmp/RC); please specify
only one
BTW, why do you use the extra ‘–’ in your example? (Not that it helps
me either way.)

Looks like a bug.

Well. If a maintainer of rubygems reads this, I believe it should be
included.
(I tried to submit the patch via rubyforge, but I don’t have an account
there.)

Well, that would explain why, when I run unpack using those dahss it
ignore the subsequent --target option.
I’m thinking now that if you are unpacking foo.gem then, by default, it
will go into foo/ (which is the same as having no --target option, and
which is what you get using the ‘–’ as you have).
If you run
gem unpack foo.gem – --target bar
I think you’d still get a foo/ directory, not bar/
