Hi, guys.
I want An agent on machine, so that it can fake user actions.
class Agent
def initialize(user, dir)
@user = user
@dir = dir
end
def mkdir(dir)
bak = Process.euid
`mkdir`
Process.euid = bak
end
def create_file(file, content)
bak = Process.euid
`echo #{content} > #{file}`
Process.euid = bak
end
end
My problem is, I have a very long list of actions, like mv, touch, mkdir,
rm, etc.
I don't want to add save and restore euid for all methods.
I kind of guess here I should use some meta programming skills. here's what
i tried.
class Agent
def self.as_me_do(method_name, &block)
define_method method_name do
block
end
end
as_me_do mkdir do
`mkdir #{dir}`
end
end
but this still generate code duplications, and it doesn't work.
I'm not sure how this could be done gracefully.
Any one been here before?
thanks
