pure function join_to_text([separator: text], [prefix: text], [postfix: text], [limit: integer?], [truncated: text], [transform: ((K, V)) -> text]): text

Generate a textual representation of this iterable.

An optional separator, prefix and postfix can be provided. One can also provide a limit: integer?. If there are more elements in the result than limit, the elements whose indices exceed limit are omitted, and the passed truncated: text is included instead.

Examples:

[1, 2, 3].join_to_text() returns '1, 2, 3'.
[1, 2, 3].join_to_text('_') returns '1_2_3'.
[1, 2, 3].join_to_text('*', '(', ')') returns '(1*2*3)'.
list<T>().join_to_text('!', '(', ')') returns '()' (where T is a valid type).
range(10).join_to_text('', '', '', 5) returns '01234...'.
range(10).join_to_text('', '', '', 5, 'more') returns '01234more'.

Where the function even is defined:

function even(x: integer): text {
   return if (x % 2 == 0) 'EVEN' else 'ODD';
}

Then:

range(10).join_to_text('->', '{', '}', 5, '...', even(*)) returns {EVEN->ODD->EVEN->ODD->EVEN->...}.
