In both the IRB from Ruby 1.6.4 and irb-0.9-02.07.03.tgz from RAA,
there appears to be a bug in the handling of $irbrc: it’s ignored.
I think the problem is in init.rb, here:
def IRB.run_config
if @CONF[:RC]
rcs = []
rcs.push File.expand_path("~/.irbrc") if ENV.key?(“HOME”)
rcs.push ".irbrc"
rcs.push "irb.rc"
rcs.push "_irbrc"
rcs.push “$irbrc” ### Here
# now try each file.
Note the quotes around “$irbrc”. I suggest the last line read like this:
rcs.push $irbrc if $irbrc
That works when I try it.
···
I’m tempted to suggest that $irbrc come first in the list of init
files to try, rather than last. I’m tweaking IRB to be a command-line
interface to an application. I have to delete HOME from ENV to avoid
having ~/.irbrc loaded instead of the application-specific init file
$irbrc names.
Since I may be the first person ever to use $irbrc, it seems unlikely
the change would break someone else’s code. However, it would make a
lie of the sentence in Programming Ruby that describes the load
order.

If I told you this mail message would have an attachment, it doesn’t
seem to, and you use Outlook to read mail: you’ve probably been
bitten by an Outlook bug. The attachment is really there, Outlook
just isn’t showing it to you. You can still save it with File | Save
Attachments. (If that doesn’t work, I must have forgotten to attach
the file.) I’m sad when my choice of a Macintosh and the Eudora
mailer is an inconvenience to others.

A file name called $irbrc exists for BOW.
BOW stands for “BSD on Windows”.

Both are written in Japanese.
However, BOW is hardly used any longer and don’t refer to
this file name for it.

Interesting! Should I make an RCR that IRB obey a global variable $irbrc rather than (in addition to?) the file named by the string "$irbrc"?

I would be happy to correct every copy brought to the Ruby Conference.

Hi,
In [ruby-talk:48526] the message: “Bug report: $irbrc does not affect
IRB”, on Aug/29 13:34(JST) Yukihiro Matsumoto writes:

$irbrc rather than (in addition to?) the file named by the string
“$irbrc”?
Then who should set up the value of $irbrc?
Maybe, for embedding irb to another application. I don’t think
positively support for embedding irb at the moment.
You can redefine Irb.run_config in your application.
def IRB.run_config
if @CONF[:RC]
rcs =
rcs.push File.expand_path(“~/.an_app_rc”) if ENV.key?(“HOME”)
:
or you can write .irbrc next:
if $0 == “app_name”
require “.app_rc”
exit
end
