indent Function

indent adds a given number of spaces to the beginnings of all but the first line in a given multi-line string.

indent(num_spaces, string)

Examples

This function is useful for inserting a multi-line string into an already-indented context in another string:

> "  items: %{indent(2, "[\n  foo,\n  bar,\n]\n")}"
  items: [
    foo,
    bar,
  ]

The first line of the string is not indented so that, as above, it can be placed after an introduction sequence that has already begun the line.
