File scope variable

Martin Martinos

10/3/2007 3:33:00 AM

I tried to find a way to have a variable that has a file scope. A
variable that I can access in each function of each class but which is
private to my .rb file.

Does anybody has a idea?

Yes. Don't do it. That's a horrible idea. If a method in your class
needs a value, pass the value as an argument.

I agree with you on this point, but in some circumstance it would be
interesting to have file scoped variables. There are at least one
built-in variable that is local to the current file and it's the
__FILE__ variable. In fact in my require function I would use a local
variable that tells me what is the current file folder path. I would
also use it to localize the path of the binary files that my script
uses. I don't think in that case its a bad idea since __FILE__ has also
a file scope.

example:

require 'pathname'
my_path = Pathname.new(__FILE__).realpath.dirname

require my_path +'mylib'

def exec_my_bin()
`#{my_path + 'bin/mybin'}`
end

Well, it's not that __FILE__ has a file scope, it's that it is a
pseudovariable which is magically set to the current file name.

If you really need to do this, maybe a hash keyed by __FILE__ sort of
like a file-local as an analogy to a thread local variable.

What is wrong with this solution? my_path *is* visible in the current
file only as far as I can see. Btw, what are you trying to achieve?

Kind regards

In fact, it only visible in the current file but it's not visible in the
exec_my_bin() function and I don't want to write:

def exec_my_bin()
`#{Pathname.new(__FILE__).realpath.dirname + 'bin/mybin'}`
end

Also I don't want to use a global variable, which I think is a bad idea
since I don't want to use it in another file.

Thanks

Right you are. I overlooked that one. You could work around that
using a lambda:

$ ruby <<XXX
> foo = 100
> bar = lambda { puts foo }
> bar[]
> XXX
100

Reasonable. But still, what do you need that for?

Kind regards

Oh yeah, and "Undercover Boss, Epic Employees"

In theory this was a go-back to see how the employees shown on
previous episodes did with their big gifts and new promotions. In
fact it looks like it was filmed no more than a month later, and none
of the parts that I saw showed anything new - except that the fat
*boss* from one episode managed to lose 100 pounds, so I guess some
time must have passed there. But they did get one thing right,
several times I heard, "I got this $20,000 for appearing on Undercover
Boss", which was unfortunately true, even though the show makes out
that the gifts are FROM the boss for previously undiscovered merit.

The show often rubs me the wrong way, showing struggling people in
underpaid jobs, clueless bosses, dysfunctional organizations.

This upcoming Fox show, what's the title, "Toxic Office: Does Someone
Have to Go?", now that is going to be something. Will everyone there
get $20,000 for appearing?

It also seems like it would engender a lot of bad morale among the rest
of the employees. "So Jane gets teamed up to work with the boss the day
he comes in and comes out of it with 20 grand and I still have to sweep
floors for minimum wage?"

Good stuff until the end

Having him go on vacation to India and not hear from him for a few

But another Canadian Bertram actress? What are the odds she's related

And then he comes back with Priya, easily the hottest of the BBT women.
Or maybe he stays in India and sends Priya back in his place. Yeah, that
works better.
