Namespaces
	utility
	unresizable vector whose size is known at compile time, which may be allocated on the stack, and which indexes from 0.

Functions
void	utility::ReadFromFileOrDie (const std::string &filename, std::string *contents)
	Reads the contents of <filename> into <contents>, preserving newline characters. Aborts if an error is encoutered. More...
utility::vector1< std::string >	utility::split (const std::string &s)
	split given std::string using ' ' symbol. More...
utility::vector1< std::string >	utility::split_whitespace (const std::string &s)
	split given std::string using whitespace as a separator. Unlike string_split_multi_delim(), any group of mixed whitespace counts only as a single seperator. More...
std::string	utility::join (utility::vector1< std::string > const &s, std::string const &connector)
	combine strings with anything More...
std::string	utility::join (std::vector< std::string > const &s, std::string const &connector)
	combine strings with anything More...
std::string	utility::replace_spaces (std::string const &string_w_spaces, std::string const &replacement)
	replace space separations in a string with a connector such as '_' More...
std::list< std::string >	utility::split_to_list (const std::string &s)
	split given std::string using ' ' symbol. More...

utility::vector1< std::string >	utility::string_split (std::string const &in, char splitchar)
utility::vector1< std::string >	utility::string_split_simple (std::string const &in, char splitchar= ' ')
	split to vector1< std::string > using arbitrary split character, but no empty strings (closer to python string::split) More...
utility::vector1< std::string >	utility::string_split_multi_delim (std::string const &in, std::string splitchars)
float	utility::string2float (std::string st)
	convert a string to a float, returns -1 on failure More...
int	utility::string2int (std::string st)
	convert a string to an int, returns -1 on failure More...
platform::Size	utility::string2Size (std::string st)
	convert a string to a Size, returns numeric::get_undefined_size() on failure More...
platform::Real	utility::string2Real (std::string st)
	convert a string to a Real, returns numeric::get_undefined_real() on failure More...
void	utility::string2uint (const std::string &x, unsigned int *y)
bool	utility::trimmed_compare (std::string const &s1, std::string const &s2)
	compares two strings ignoring leading and trailing spaces More...
bool	utility::startswith (std::string const &haystack, std::string const &needle)
	True iff haystack starts with needle. More...
bool	utility::endswith (std::string const &haystack, std::string const &needle)
	True iff haystack ends with needle. More...
void	utility::slurp (std::istream &in, std::string &out)
void	utility::trim (std::string &s, const std::string &drop)
std::string	utility::trim (std::string const &s, std::string const &drop=" ")
	create a new string that drops all the unwanted substrings of the original string. More...
void	utility::add_spaces_left_align (std::string &st, std::size_t const newlen)
	adds spaces to a left aligned string until a given length is reached More...
void	utility::add_spaces_right_align (std::string &st, std::size_t const newlen)
	adds spaces to a right aligned string until a given length is reached More...
bool	utility::is_string_numeric (std::string const &input)
std::string	utility::file_contents (std::string const &file_name)
	Read the entire contents of a file into a string. All end-of-line characters are replaced by "\n". Throws a utility::excn::EXCN_msg_exception if the file cannot be opened. More...
std::string	utility::file_basename (const std::string &full_path)
std::string	utility::filename (const std::string &path)
std::string	utility::pathname (const std::string &path)
std::string	utility::replace_environment_variables (std::string input)
	find all environment variables with the form ${VARIABLE} and replace with the contents of that environment variable. if the environment variable does not exist, return string::npos More...
