Irb

Is there any way to reset irb without closing and restarting it?

2

I have this function in my .irbrc:
def reset_irb
   exec($0)
end

Effectively its closing and restaring it, but its a little faster, I think

I don't know if this is any help, but do you know about IRB's
workspaces?

cool.
I'll try it, as soon as I figure out what ~/.irbc equates to under
Windows.

I use Linux at home, but I can't get a linux machine at work. So I'm
using my spare time at work to learn Ruby on Windows, hoping that all is
reasonably transferrable.

Cool.

Workspaces seem to share class definitions (if a class is created or
modified in one workspace it is visible in all workspaces) but regular
objects created in one workspace are not available in other workspaces.

Awesome, Logan. I didn't even know I could use an rc file.

On Win2k and later, it should be by default C:\Documents and Settings\<user

\.irbrc

Also, the Ruby interpreter should happily take "~" as a file path even on
Windowsenso you can have it expand into the real path with one of the file
name manipulation functions. (Which I've never used, so you're stuck to
reading the docs as to what tells you the absolute path.)
