Hi,
I'm learning Ruby from the pickaxe book and I'm using the IRB to try
out examples. I'd like to know if it is possible to save to disk the
IRB session so that when I come back I can load up a session to the
state it was in before. Is this possible?
Thanks,
Matt
I do not think so. You certainly can store objects to disk (using Marshal or Yaml) but then you would still be missing a lot info (local variables, files to require etc.)
If you are on a Unix a workaround might be to use screen.
Kind regards

This comes up from time-to-time. I don't know if
there is a hands-down winner, but
saving irb session - Google Search
turns up at least two answers:

Cool! That looks fairly easy. /me makes mental note.

Even better, Ben Bleything showed off his IRb enhancements for this in a RubyConf 06 lightening talk. They are quite smooth.
You can get Ben's code from his blog:

Thanks for the mention, James!
I've been meaning to get that cleaned up and post usage examples and
whatnot. In the meantime, if anyone has any questions or suggestions,
I'd be happy to hear 'em.
It also sounds as if Nick Sieger and I are going to be pooling resources
and putting out a gem soon full of similar IRB hacks. Watch this space

No one mentioned Wirble, even though it's linked from Ben's post:
http://pablotron.org/software/wirble/
Setup:
$ sudo gem install wirble
$ cat > ~/.irbrc
%w{rubygems wirble}.each { |lib| require lib }
Wirble.init

In the history realm, does wirble do more than just enabling readline?
I use it for colorization and that, but haven't been able to figure out
much else.
I also emailed you a couple of times to see if you wanted to join forces
with Nick and I, but got no response. It occurs to me now that maybe
they didn't make it through?

That's pretty much it. I went through the Ruby Garden Irb page and
snagged the useful stuff, then rolled it up with my fancy-schmancy
colorization and called it Wirble.

I didn't get them. I've been getting over 20k spam messages per month
for the last two months, so it's possible they may have gotten snagged
by my spam filter.
I'll check my spam folder; it might be time to set up a whitelist and/or
re-train spamprobe.

I just checked through my spam folder from last month and I didn't see
anything from you. What address did you email (I'm trying to figure out
if I'm losing mail or if the messages got routed to some other folder).
Anyway, I'm interested in collaberating, or, at the very least,
borrowing your guys' hard work and shamelessly rolling it in to Wirble
:).
PS. As of October, I'm officially over 30k spam messages per month --
Yipee.

Just FYI, there's a bug in Wirble's colorization I'm hitting pretty often. This exposes it:
>> class Example
>> attr_writer :var
>> end
=> nil
>> ex = Example.new
=> #<Example:0x74722c>
>> ex.var = {:one => 1, :two => 2}
=> {:one=>1, :two=>2}
>> ex
=> #<Example:0x74722c @var={:one=>1, :two=>2}

Well now, that's no good. I'll toss it in my pile o' bugs.
Thanks!
