Add comment to line in multiline %w in ruby

Question

I have a multiline string array via percent string like this:

array = %w(test
           foo
           bar)

I want to add a comment message to the foo entry, something like

array = %w(test
           # TODO: Remove this line after fix #1
           foo
           bar)

Is there any way to do it without converting it to basic array like this?

array = ['test',
         # TODO: Remove this line after fix #1
         'foo',
         'bar']

Answer 1

I think there is no way to make that work, because %w() evaluates every space delimited element inside it to string.

There's no way from inside the string to make Ruby evaluate that string.

Answer 2

The only and tricky way:

array = %W(test
           #@foo
           bar).reject(&:empty?)

Note capital W and reject
