I have something like this:
[#TrajectoryMeasurement depth: 0, move_e: 234>,
#TrajectoryMeasurement depth: 1475, move_e: 123>]
How to convert it to:
[[0, 234], [1475,123]]

1This is not a Hash. This is an array of objects.quetzalcoatl– quetzalcoatl2013-12-05 09:28:19 +00:00Commented Dec 5, 2013 at 9:28

@quetzalcoatl It is neither. It is not a valid Ruby code.sawa– sawa2013-12-05 09:29:12 +00:00Commented Dec 5, 2013 at 9:29

@sawa: I'll not argue, I'm just guessing as the notation seems broken to me. Is it a normal dump of some construct?quetzalcoatl– quetzalcoatl2013-12-05 09:31:13 +00:00Commented Dec 5, 2013 at 9:31

@plewas, does TrajectoryMeasurement respond to methods depth and move_e?BroiSatse– BroiSatse2013-12-05 09:31:46 +00:00Commented Dec 5, 2013 at 9:31

@quetzalcoatl I checked the source of the OP's original posting. I don't think the mess is because of interaction with the markup. The OP simply posted invalid code.sawa– sawa2013-12-05 09:43:44 +00:00Commented Dec 5, 2013 at 9:43

If it's an array of objects as I suspect you can use the #collect method on Array:
array = [#TrajectoryMeasurement depth: 0, move_e: 234>,
#TrajectoryMeasurement depth: 1475, move_e: 123>]
array.collect { |x| [x.depth, x.move_e] }
# => [[0, 234], [1475, 123]]

Supposing you really had a hash, all you need is calling .to_a to get exactly what you asked for.
{a:1, b:1}.to_a => [[:a, 1], [:b, 1]]
Alas, as it was said before, it wouldn't see, what you have there is a Hash, unless that's an ad-hoc representation of it.

Depending on the structure of your hash you might also want to have a look at .flatten.
