Calling a Method

Ron Green

9/17/2008 4:28:00 PM

If I have a file that contains a method that takes one parameter. and
I want to call the method from the command line, how do you do that?
I know how to run a script from the command line but not how to call a
method.

I'll be interested to see if there is a better way to do this...

npowell@delilah ~ $ cat test.rb
class Foo
def bar
puts "Oh Hai!"
end
end
npowell@delilah ~ $ ruby -e 'require "test"; f = Foo.new; f.bar;'
Oh Hai!

Is this what you mean?

henning@box:~$ cat test.rb
def bar(p=ARGV[0])
puts "bar called with parameter '#{p}'"
end
henning@box:~$ ruby -rtest -e 'bar' Hello
bar called with parameter 'Hello'

Nice. I should have looked at the Ruby man page. -r makes sense.

Though I would have done this:

npowell@delilah ~ $ ruby -r test -e 'bar("Oh Hai")'
Oh Hai

Just to keep from having to add the ARGV[0] as the default value.

Re: CBS reports on Dims calling Tea Party racists...

In your post, you gave a YouTube video of some of Carter's statements
about Tea Party participants

In the YouTube video you cited, Carter states (with MY CAPS)

"I think that an overwhelming portion of the INTENSELY DEMONSTRATED
ANIMOSITY toward President Barack Obama is based on the fact that he
is a black man."

During that video, a rectangular baloon at Carter's mouth says Carter
denied having said this. He did not deny saying it, but corrected a
reporter who stated:

"You said OVERALL that you thought the protesters were upset that
there was a black president, that there was racism involved....."

Carter cut her off and corrected her. He said the VITUPERATIVE
attacks were racially motivated. For your edification, vituperative
means: Criticism or invective which is sustained and considered to be
OVERLY HARSH. That is to say, intensely demonstrated animosity: that
which comes from the fringe elements. Carter makes this very clear.


There are two videos of these interviews that can be seen at one URL

http://www.abovetopsecret.com/forum/thread...

So much of what I see posted by the Right on this group is based on a
child like interpretation of what is actually said. I hate to say it
(but secretly enjoy it): RightWingers posting on this group are
stupid. Illiterate. Gullible.

Obama has surrounded him self with 'violent' radicals who committed
