# StringSplitter Library for Arduino An Arduino library that adds string splitting functionality to character delimited C++ strings. ## Features - Adds string splitting functionality to Arduino. - Can specify the maximum number of substrings, via ``limit`` up to ``MAX``. - ``MAX`` is ``5`` by default and can be overridden in ``StringSplitter.h``. - ``limit`` equal to and below ``1``, returns the whole input string. - The last substring contains the remaining part of the whole string, including delimiters. - If delimiter is not found, the whole string can be found in the first substring. ## Methods #### 1. Initialization #### ``` new StringSplitter(String input, char delimiter, unsigned int limit); * Return: StringSplitter object. * input: String with delimiters to be split. * delimiter: Character around which string will be split. Not included in substrings. * limit: Maximum number of substrings. Overriden by MAX in StringSplitter.h ``` #### 2. Get Substring Count #### ``` int getItemCount(); * Return: Number of substrings. Min = 1, Max = (limit or MAX, whichever is lesser). ``` #### 2. Get Substring at Index #### ``` String getItemAtIndex(int index); * Return: Substring of input string. * index: Position of substring with respect to the input string. Starts from 0. ``` ## Usage ``` #include "StringSplitter.h" StringSplitter *splitter = new StringSplitter("abc,def,ghi,jkl", ',', 3); int itemCount = splitter->getItemCount(); for(int i = 0; i < itemCount; i++){ String item = splitter->getItemAtIndex(i); } ```
