Re: Rubygems 1.3.5 can't load 'rubygems/defaults/operating_sy..'

drbr...@segment7.net (Eric Hodel) — Tue, 24 Nov 2009 01:58:09 UT

It's a feature of ruby -d
$ ruby -de 'begin; raise; rescue; end; p :ok'
Exception `RuntimeError' at -e:1 -
$ ruby -de 'begin; require "no such file"; rescue LoadError; end; p :ok'
Exception `LoadError' at -e:1 - no such file to load -- no such file
it prints for every raised error, even if caught.

Thanks! This conveniently aligns with what I'd concluded; looks like
PDF::Writer isn't updated for 1.9, and Prawn looks nice.
Although it worries me a bit that I get a ton of warnings running it under
1.9. But they look harmless.

Re: What is FILE and $0? (newbie question)

ni...@slaphack.com (David Masover) — Tue, 24 Nov 2009 01:31:47 UT

I'm not sure that would always work...
$0 is probably named after the same variable in the shell -- it tells you how
the current program was executed.
__FILE__ is the name of the current file, wherever it's accessed.
It seems that what they're trying to do is only run the main loop when your
program is run as a program, and not when it's used as a library. That is, if

Hello everyone,
I am new to Ruby, learning the basics, and the basics of FXRuby (I
know this is not the FXRuby forum, but I think this question pertains
Ruby per se). I've noticed the "recommended" way of creating the main
app loop goes like this:
if __FILE__ == $0
#main loop code
end
I've already done some GUI apps, and had no need of these wierd

Printing from Ruby

usenet-nos...@seebs.net (Seebs) — Tue, 24 Nov 2009 00:35:17 UT

Long story short: I wanted to make pretty-printed stuff. I have, after
several hours, gotten something that can produce acceptable output by
rendering as HTML, which I then run through Firefox -- with five mostly
undocumented about:config changes and an elaborate printing procedure.
That sucks.
I am looking for the ability to do things that are frankly not much beyond

[ANN] mail Gem version 1.3.0

raasd...@gmail.com (Mikel Lindsaar) — Tue, 24 Nov 2009 00:31:08 UT

So, mail Gem version 1.3.0 has been released.
The upgrades have been mainly in getting ActionMailer to work with Mail
instead of TMail.
This really put Mail through it's paces and I found a lot of little edge
case bugs to fix.
The good news is that ActionMailer now runs with Mail with all tests passing

transf...@gmail.com (Intransition) — Tue, 24 Nov 2009 00:09:42 UT

I'm doing a little meta-programming in this case -- I've created a
function to find "plugins". So I need to search through the $LOAD_PATH
and Gems. But I'm all ears if there is another way to do it. Here's
the code:
# = Plugin Handler
#
# Find plugins across various library managers.

module Plugin

evansen...@gmail.com (Evan Senter) — Tue, 24 Nov 2009 00:05:35 UT

I explored your idea of using inheritance a bit further, and though it's
not entirely transparent to the consuming class (super has to be called)
it is a clean implementation, and would look something like this:
class A
def initialize(&block)
@_original_self = block.binding.eval("self")
instance_eval(&block) if block_given?
