Hey all, Last year during RubyConf, I showed a little hack for adding shell-style history manipulation to irb. There was a bug in it where history replays that did assignments were executed in the wrong context, causing you to not have access to the newly-assigned variable after the replay was done. Well, today, I’m happy to announce that this critical bug has been squashed and I’ve released the 1.0 (for lack of a better version number) version of the hack. It’s available on my blog, with background info, here: [http://blog.bleything.net/2007/7/30/announcing-shell-style-history-for-irb-the-fixed-edition](http://blog.bleything.net/2007/7/30/announcing-shell-style-history-for-irb-the-fixed-edition) You can take the code linked to from that post and drop it into your .irbrc and immediately enjoy such tasty methods as h, h!, and hw. I invite you to experiment! Back when I first announced this hack, I heard from a couple of people who were interested in collaborating on a set of IRB hacks. I haven’t forgotten, I’m just a really terrible correspondent. The upshot for everyone else is that soon, you may not need to copy and paste the code! Stay tuned for more info! Ben
