Function Documentation

std::vector<std::string> StringUtils::split ( const std::string &  s,
char  delimiter,
bool  removeEmpty = false 

Split a string at a given separator.

std::vector<char*> StringUtils::makeArgv ( std::vector< std::string > &  strings)

Turns a vector of strings into a vector of char*, useful for generating argv, with the first element being a nullptr. Note: the pointers are not const char*, because this is the way argv normally is. However, I don't think getopt_long() and the likes actually change the content of the memory locations.

stringsthe vector of strings.
a vector of const char*. Each element points to the memory allocated by each of the elements of strings, and is therefore only valid as long as the latter remains unchanged.
