Required scripts

Hi everybody,

I have a question:

Is there a way to find out which ruby script files are “required”
(==loaded) by the current application?

example:

require "foo/bar"
require "this/is/a/test"
require “cgi”

get_requrired => [foo/bar, this/is/a/test, cgi]

any help will be appreciated, thanks in advance!

get_requrired => [foo/bar, this/is/a/test, cgi]

pigeon% ruby -rsocket -e 'p $"'
["socket.so"]
pigeon%

pigeon% ruby -rsocket -rcgi -e 'p $"'
["socket.so", "cgi.rb", "English.rb", "delegate.rb"]
pigeon%

Take a look at the “rdep” utility on RAA:
This utility analyzes large Ruby programs and attempts to
determine all their dependencies and whether they can be
resolved. It recognizes simple forms of load, require, and
autoload.

so rdep actually parses some Ruby code to determine these things?

How about checking the Array in $" ?

From page 217 of the Pickaxe: “An array containing the filenames of
modules loaded by require.”

That’s useful at runtime, isn’t it? But what if
you can’t run because of missing files?

BTW, “parsing” is an overly kind description of
what rdep does. It’s hardly more sophisticated
than grep.
