I confirmed Craig's behavior on 1.9.1 and 1.8.7 on Mac OSX and 1.8.7
on Ubuntu 9.10. I also tested on a Turnkey RoR VM appliance using Ruby
1.8.6 on Ubuntu 8.04 (LTS).

The only thing I can see is Robert is running some version of 1.8 that
was installed via a package manager (like apt-get). I'm guessing that

Hello all,

I'm looking for the equivalent of 'grep -v' in ruby. For example,
let's say I have the following array:

a=%w(foo bar bat)

I can grep for those items that have an /b/ with this:

irb(main):016:0> a.grep(/b/)
=> ["bar", "bat"]

I would like to be able to grep by specifying a negative, such as,

Don't have one, yet. Was just getting to that chapter in the pickaxe
book, when I inadvertently packed it in a box for moving. I'll
probably find it later tonight.

$ (set -x ; ruby -v ; irb -v ; lsb_release -a )
+ ruby -v
ruby 1.8.6 (2007-09-24 patchlevel 111) [i486-linux]
+ irb -v
irb 0.9.5(05/04/13)

You've really got 2 problems here, and I'm not sure how related they
are. First, the rescue clause isn't working. On my system, that
statement returns nil. Second, your IRB is exiting on errors. My IRB
session prints the traceback if I remove the rescue clause, but then
gives me another IRB prompt.

That didn't work for me. irb still exits on errors.

Yup, lot of variation is possible. I was trying to make each script
the most readable in that language and the most familiar to those not
versed in that language.

Interesting. I usually go the other way, using double quotes by
default unless I need single quotes, mainly because double quotes

I didn't know you could do that...

Luis commented on the Google group for RubyInstaller (The 5-click
Installer :) that gemcutter works with it, but he hasn't tested
jeweler. (if it doesn't shell out to *nix commands, it shuld be fine).

So he is aware of the move.

Gem's must from now on be "pushed" to gemvutter, if hosted on RF:

Duh. I should have realized that I should look in the String class for
the [] method. Even crazier is the assignment form:

str[regexp, fixnum] = new_str

I had a hard time finding documentation for __FILE__. It turns out
that it's a Ruby keyword, and a pseudo-variable, like true/false/nil/

I'd be willing to do a 15 minute talk on jeweler. I think it's the
bees knees.

Craig,

There is some discussion on this in the Ruby dev list (where Matz
hangs out). I'm not sure where he is going to end up, #Kernel.__dir__,
__dir__(*paths), __DIR__ or __DIR__(*paths). I think the consensus
might be for __DIR__ as a constant as you say. You can write your own
function that does a similar thing, assuming __DIR__ exists:

You can still pull down sources from Github via GIT, you just can't
pull them as a single file via gems. As I understand it, the idea is
to keep your development in Github (or anywhere else you care to) and
push to Gemcutter in addition to that.

I don't think Curt is involved much with the Windows Once-Click

The commenter you're talking about is probably Luis Lavena. He took
over as maintainer of the OneClick installer - now known as
RubyInstaller[1] - in December of 2007[2].

Craig, you are probably right about the dependencies. Note net-ssh,
json, etc. Needed for the push process, but not for backtracer itself.
However, based on your news re: the switch to rubygems.org
(Gemcutter), it can't hurt to have these installed.

I hope Curt Hibbs is reading thius. One of the commenters mentioned

Re: require File.expand_path(File.dirname(FILE ...

I don't much care for allowing __DIR__ to take args as a method.
__FILE__ is just a constant String, and I think __DIR__ should mirror
its implementation as much as possible.

The regex matches up until it reaches a colon, some digits (\d+), and
another colon. Then it stores what got matched within the parentheses.
