Hello,
when I run a ruby script how can I determine all the modules that are
getting loaded?
Thanks
ObjectSpace.each_object(Module) {|m| p m}
Alternatively you could try to traverse across all constants, e.g.
seen = {}
queue = [Object]
until queue.empty?
x = queue.shift
seen = x
p x if Module === x
if Module === x || Class === x
x.constants.each do |c|
o = x.const_get c
queue << o if !seen[o] && (Module === x || Class == x)
end
end
end
Kind regards
robert

Do you actually mean Module or "package like thing". I ask simply because of the ambiguity of the word "loaded".

I don't know if that's what you are looking for, but there's also the
$LOADED_FEATURES variable (aka $").
ruby -e 'puts $LOADED_FEATURES'
Robert thank you, I was not expecting to see that many modules getting dumped!

Alternatively you could try to traverse across all constants, e.g.
seen = {}
queue = [Object]until queue.empty?
x = queue.shift
seen = xp x if Module === x
if Module === x || Class === x
x.constants.each do |c|
o = x.const_get c
queue << o if !seen[o] && (Module === x || Class == x)
end

Hello,
so how do you get a list of all used gems / things that are required?
Thanks
Berg
What I used the word module I meant is in the sense of a module file
that gets pulled in using require.
From the initial source file it's easy to just look at all the require
statement, however the included modules may have dependencies on other
modules, so I wanted to determine a list of these modules getting
loaded for the code to function.
I assume this would also allow me to figure out things like what ruby
gems are being loaded?

Robert, Lucas thanks the output seems more manageable, I'll play
around with both and do more reading up.

You might be able to pull something off with set_trace_func. Try
$ ruby -e 'set_trace_func ->(*a){p a};require "thread"'

Yeah, probably. I guess you can also find a constant that contains
loaded gems somewhere.
Kind regards
