Execute ruby commands in a program

Haze Noc

8/18/2007 4:17:00 PM

Ok so lets say i have a program, And within the program i call a command
such as Ruby: <command>

Is there anyway to be able to run live ruby code and print the answers
(i dont really know how to put it) so like..

Ruby: name = 'john'; puts "Hi" if name == 'john'
Program: Hi


Sounds weird i know, But if Anyone out there understands me that would
be great..

I want to stay away from shell one liners like ruby -e "code here"

Thanks in advance

Um, this sounds like 'irb'. Depending on what OS you're on and how
you installed ruby, you should just be able to type 'irb' at the
command-line. That sounds like what you're after.

I have a bit of trouble understanding what it is you want to have
happen, especially since you specifically wish to avoid 1-liners.

Is "irb" (bundled with ruby) what you want?

Absent that, at the shell you can just run "ruby", type some ruby
code, then type
__END__
on a line by itself, (that's two underscores, then END, then two more
underscores) and the code will then run.

Is either of this what you wanted?

Sorry its quite hard to explain, Its not IRB, because i want to actually
run a command from within another ruby script.. Lets say i wanted to do
a 1 liner from within the program i could do something like..

me: ruby puts "Hello"
script runs `ruby -e "puts 'Hello'"
Program: Hello

But i didn't really want to do any 1 liners, althouth if i did, lets say
i have

while msg = gets
if msg =~ /^ruby (.+)/i
msg.gsub!(/\"/, "'")
message = `ruby -e "#{$1}"`
puts message
end
end

and input was..

puts 'hello'

How could i return the input?

....

On CNN yesterday, Abercrombie acknowledged that more documentation may
not satisfy the birthers, but said he was acting because of his personal
disgust with the claims and the fact that he knew Obama's parents back
in college when Obama was born and is deeply offended at claims he knows
to be false.

"It's a matter of principle with me. I knew his mom and dad. I was
here when he was born. Anybody who wants to ask a question honestly
could have had their answer already," he told CNN.

Fuck off, Shill, you psychokooker birther.

He can say lots of shit, Cuntston - doesn't make any of it true.
