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.
