Namespaces
namespace	string_util
	some common string processing functions, for std::string
Functions
char	string_util::localeToUpper (char c)
	uses the standard library's "locale" to convert case of a single character
char	string_util::localeToLower (char c)
	uses the standard library's "locale" to convert case of a single character
string	string_util::makeUpper (const std::string &s) ATTR_must_check
	returns upper case version of s
string	string_util::makeLower (const std::string &s) ATTR_must_check
	returns lower case version of s
string	string_util::removePrefix (const std::string &str, const std::string &pre) ATTR_must_check
	returns str with pre removed - if pre is not fully matched, str is returned unchanged
string	string_util::tildeExpansion (const std::string &str) ATTR_must_check
	replaces ~USER prefix with specified user's home directory, or ~ prefix with current HOME environment setting; returns str if no valid expansion is found
string	string_util::trim (const std::string &str) ATTR_must_check
	removes whitespace (as defined by isspace()) from the beginning and end of str, and returns the result
bool	string_util::beginsWith (const std::string &str, const std::string &prefix)
	returns true if str begins with prefix
bool	string_util::endsWith (const std::string &str, const std::string &suffix)
	returns true if str ends with suffix
std::string	string_util::makePath (const std::string &rel, const std::string &path)
	Returns tgt if it is an absolute path or rel is empty, otherwise drops trailing file (if any) from rel and appends tgt.
std::vector< std::string >	string_util::tokenize (const std::string &str, const std::string &delims=", \t")
	convert input string into vector of string tokens
bool	string_util::parseArgs (const std::string &input, std::vector< std::string > &args, std::vector< unsigned int > &offsets)
	parses the input string into an arg list, with corresponding offsets of each arg in the original input
bool	string_util::reMatch (const std::string &str, const std::string &regex)
	returns true if str matches re (assumes 'extended' regular expression, not 'basic'), false otherwise and throws std::string message on error
bool	string_util::reMatch (const std::string &str, const std::string &regex, int flags)
	returns true if str matches re (with optional flags to control interpretation), false otherwise and throws std::string message on error
std::string	string_util::intToStringIP (int ip)
	Converts a int representation of an IP to a string.
int	string_util::stringToIntIP (std::string ip)
	Converts a string representation of an IP to an int.
size_t	string_util::utf8len (const std::string &str)
	returns the number of utf8 code points found in the string
std::string	string_util::demangle (const std::string &symbol)
	returns demangled version of a symbol name
std::string	string_util::int2str (int const n)
	convert int to string so robot can speak numbers
Variables
static const std::locale &	string_util::curLocale = std::locale::classic()
	reference to the current standard library 'locale'
