IO Namespace Reference

Detailed Description

In-out (timers, profilers, and read/write data)

Namespaces
namespace	FRW
	File read/write utilities: text parsing and binary I/O.

Classes
class	ChronoTimer
	Class that uses std::chrono to easily time code. More...
class	InputBlock
	Holds a named list of key=value options and nested InputBlocks. More...
struct	IsArray
	Compile-time trait: IsArray<T>::v is true if T is std::array. IsArray<T>::t is the element type; IsArray<T>::size is the extent. More...
struct	IsVector
	Compile-time trait: IsVector<T>::v is true if T is std::vector. IsVector<T>::t is the element type. More...
struct	Option
	Simple struct; holds key-value pair, both strings. == compares key. More...

Functions
void	unkown_option (std::string_view test_string, const std::vector< std::string > &list)
	Prints unkown option warning, with suggested alternative.
std::string	removeSpaces (std::string str)
	Removes all white space (space, tab, newline), except for those in quotes.
std::string	removeQuoteMarks (std::string str)
	Removes all quote marks.
void	removeBlockComments (std::string &input)
	Removes all c++ style block comments from a string.
std::string	removeComments (const std::string &input)
	Removes all c++ style comments from a string (block and line)
std::string	expandIncludes (std::string input)
	Expands "#include" files.
template<typename T >
T	parse_str_to_T (const std::string &value_as_str)
	Parses a string to type T by stringstream.
std::string	file_to_string (const std::istream &file)
	Parses entire file into string. Note: v. inefficient.
void	print_line (const char c=' *', const int num=80)
	Prints a line of 'c' characters (dflt '*'), num chars long (dflt 80) to cout.
std::string	time_date ()
	Returns current local date and time as a string, e.g. "2026-05-14 13:01:02".
std::string	date ()
	Returns current local date as a string, e.g. "2026-05-14".
std::string	time ()
	Returns current local time as a string, e.g. "13:01:02".
bool	operator== (InputBlock block, std::string_view name)
bool	operator== (std::string_view name, InputBlock block)
bool	operator!= (InputBlock block, std::string_view name)
bool	operator!= (std::string_view name, InputBlock block)
