Question

I have a small Ruby script where an array is initialized to hold a few strings

MyArray = ["string 1", "string 2" , "string 2" ]

The problem is that I have quite a few strings in the initialization list and I would like to break the line:

MyArray = [
            "string 1"
           ,"string 2" 
           ,"string 2"
          ]

but Ruby flags a syntax error for this format
I tried adding “\” to the end of each line without any success.

How can this be accomplished in Ruby?

Answer 1

You will want to put the comma, after the item like so

myarray = [
  "string 1",
  "string 2",
  "string 3"
]

Also, if you might be thinking of putting the comma before the item, for say easy commenting or something like that while your working out your code. You can leave a hanging comma in there with no real adverse side effects.

myarray_comma_ended = [
  "test",
  "test1",
  "test2", # other langs you might have to comment out this comma as well
  #"comment this one"
]

myarray_no_comma_end = [
  "test",
  "test1",
  "test2"
]
