std::vector< std::string > utils::quoted_split (const std::string &val, char c=',', int flags=REMOVE_EMPTY|STRIP_SPACES, char quote='\\')
 This function is identical to split(), except it does not split when it otherwise would if the previous character was identical to the parameter 'quote' (i.e. More...

std::string utils::bool_string (const bool value)
 Converts a bool value to 'true' or 'false'. More...
std::string utils::signed_value (int val)
 Convert into a signed value (using the Unicode "−" and +0 convention. More...
