Ok, so I have this array of pairs that control file movements, for
organizing directory trees. It looks something like this:
rules = [
['(.+).tgz', 'tars/$1'],
['(.+)-(.+).war', '$1/webapps/$2'],
# and so on...
]
Then, I want to iterate through these, capturing the regex matches and
using them in the paths on the right side of the hash. I have something
like this:
file = 'abc.tgz' # just for example
dest = ''
rules.each do |row|
if file =~ %r{^#{row[0]}$}
eval "dest = \"#{row[1]}\"" # XXX broken: want to ref matches
break
end
end
puts dest # "tars/$1", instead of "tars/abc"
The problem is, I can't get the matches to show up inside the eval. I've
tried %Q, different quote combinations, etc. Anyone know a way to make
this work?
Thanks,
Nate
