VALUE rb_str_ellipsize ( VALUE  str,

Shortens _str_ and adds three dots, an ellipsis, if it is longer than _len_ characters.

Parameters:
str the string to ellipsize.
len the maximum string length.
Returns:
the ellipsized string.
Precondition:
_len_ must not be negative.
Postcondition:
the length of the returned string in characters is less than or equal to _len_.

If the length of _str_ is less than or equal _len_, returns _str_ itself.

the encoding of returned string is equal to the encoding of _str_.

the class of returned string is equal to the class of _str_.

Note:
the length is counted in characters.
