The result is a String, which is part of {src}, starting from byte {start}, with the byte length {len}. When {chars} is present and TRUE then {len} is the number of characters positions (composing characters are not counted separately, thus "1" means one base character and any following composing characters). To count {start} as characters instead of bytes use |strcharpart()|. When bytes are selected which do not exist, this doesn't result in an error, the bytes are simply omitted. If {len} is missing, the copy continues from {start} till the end of the {src}. strpart("abcdefg", 3, 2) == "de" strpart("abcdefg", -2, 4) == "ab" strpart("abcdefg", 5, 4) == "fg" strpart("abcdefg", 3) == "defg" Note: To get the first character, {start} must be 0. For example, to get the character under the cursor: strpart(getline("."), col(".") - 1, 1, v:true) Can also be used as a |method|: GetText()->strpart(5)
