Issue

I have a Ruby script that outputs an array:

arr = ["filename1", integer1, integer2, "filename2", integer3, integer4, "filename3", integer5, integer6 ...]

What I need is this array to be more readable; I'd like to print only three elements in a single line, so:

"filename1", integer1, integer2,
"filename2", integer3, integer4,
"filename3", integer5, integer6,

I managed to get to the point of having an array of arrays with arr.each_slice(3).to_a:

arr = [["filename1", integer1, integer2], ["filename2", integer3, integer4], ["filename3", integer5, integer6] ...]

but I still can't make each array of the array be printed in a separate line.

Is there a way of doing this?

The ideal output would look something like this:

filename1: integer1, integer2
filename2: integer3, integer4
filename3: integer5, integer6

but I understand that adding the colon after filename is another issue, I would probably have to play around with join().

Solution

Formatting an array can be done with the [%] method1

arr.each_slice(3){|trio| puts "%s: %d, %d" % trio}
