Ruby: how to initialize an array across several lines
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 lik开发者_高级运维e 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?
MyArray = %w(
string1
string2
string2
)
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"
]
Another way to create an array in multi-line is:
myArray = %w(
Lorem
ipsum
dolor
sit
amet
)
MyArray = Array.new(
"string 1"
,"string 2"
,"string 2"
)
