I’m new to Ruby and I am willing to learn. Anyone need help on a
project for the next 3 days? All my friends are on vacation and I have
nothing better to do. I do have programming experience in Java and C.

Have you done the Ruby Koans?
Never heard of it, but I’ll get right on it. Thanks.

“method_missing” is automagically called on a class if it doesn’t have

Thanks again for pointing me in the right direction.
No problem!
Two other sites come to mind:

Hi.
Im programming for the fun of it. I lose my internet connection
in a month, for a looong time.
So I thought if I switch to perl I can download the cpan and
have 22000 modules on my hd. So I did.
But I really,really,really prefer Ruby.
So I thought maybe I can download all of gem?
So I can stick with ruby?

There’s no free WiFi anywhere near you so you can get a few gems now and
then?
Hi,
I found “gem mirror” command in a old version of gem, but
a current version of gem doesn’t have such a command.
Now, I think that the one way to download all gem files is to do
following steps:
- obtain all gem names with “gem search” command
$ gem search --remote - download all gem files with “gem fetch” command
$ gem fetch [gemname] [gemname] [gemname] …
([gemname] is one of the gem names obtained in step 1)
Although this way is troublesome if you do by your hand,
you can write a simple script which do these steps automatically.
There might be a better way than this way, but I don’t know.
Regards,
Hi *,

using bash this might look like this:
=========================================================================
$ for GEM in $(gem search -qr | awk ‘NR>2 { print $1 }’); do gem fetch
${GEM}; done;
All available remote gems (~25k@gemcutter) will be fetched to the
current
working directory. However, this also includes all sort of garbage
modules
created for testing or those no longer under active development.
Hope this helps …
So long …

This worked for me:
$ cd some/dir/to/store/gems/in
$ gem update --system && gem search --no-installed --no-details
–no-versions --remote | awk ‘NR<10’ | xargs gem fetch --bulk-threshold

If you want all of them, just don’t pipe it through awk. I think Jan is
on
the right path with fetching the gems (as opposed to installing them,
which
could have security consequences, and probably lead to hard to track
bugs
from some gem authors not understanding the conventions). Then, when you
want one of the gems, you can cd into that dir and $ gem install gemname-version.gem
Of course, this doesn’t fetch every version of every gem, just the most
recent.
$ gem search --remote
$ for GEM in $(gem search -qr | awk ‘NR>2 { print $1 }’); do gem fetch
${GEM}; done;

thanx ill try this… im sure cpan holds some garbage modules too…
this means i can stick with ruby…

This is actually sh syntax. It just also happens to work in bash.

Expect the next version of bash to fix this bug.

Jeremy, thanks for that hint, I instantly fell in love with this site.
Unfortunately I was never great at math but I love to tinker with such

What about
$ gem19 help mirror
?

looks like it hasn’t been released as a gem yet… I haven’t seen much
movement on it lately so I don’t know the status of it.
That said… gem mirror will download ALL the gems, not just the
latest. It’s a bit heavy handed if you’re looking to do something more
casual.
