Enumerations
enum	SkipWhitespace : unsigned char { kNone = 0, kLeading = 1, kTrailing = 2, kSurrounding = 3 }
	Option to determine how to treat surrounding whitespace when scanning an input stream. More...

Functions
template<typename InputStream >
void	affirm_char_or_throw (InputStream &source, char criterion, SkipWhitespace skip_ws=SkipWhitespace::kNone)
	Lexing function that checks whether the current char from the stream equals the provided one. More...
template<typename InputStream >
void	affirm_char_or_throw (InputStream &source, std::function< bool(char)> criterion, SkipWhitespace skip_ws=SkipWhitespace::kNone)
	Lexing function that checks whether the current char from the stream fulfills the provided criterion. More...
constexpr bool	operator& (SkipWhitespace lhs, SkipWhitespace rhs) noexcept
	And-operator to check whether a SkipWhitespace is set. More...
template<typename InputStream >
char	read_char_or_throw (InputStream &source, char criterion, SkipWhitespace skip_ws=SkipWhitespace::kNone)
	Lexing function that reads a single char from the stream and checks whether it equals the provided one. More...
template<typename InputStream >
char	read_char_or_throw (InputStream &source, std::function< bool(char)> criterion, SkipWhitespace skip_ws=SkipWhitespace::kNone)
	Lexing function that reads a single char from the stream and checks whether it fulfills the provided criterion. More...
template<typename InputStream >
std::string	read_to_end_of_line (InputStream &source)
	Lexing function that reads until the end of the line (i.e., to the new line char), and returns the read chars (excluding the new line char). More...
template<typename InputStream >
std::string	read_until (InputStream &source, char criterion)
	Lexing function that reads from the stream until its current char equals the provided one. The read chars are returned. More...
template<typename InputStream >
std::string	read_until (InputStream &source, std::function< bool(char)> criterion)
	Lexing function that reads from the stream until its current char fulfills the provided criterion. The read chars are returned. More...
template<typename InputStream >
std::string	read_while (InputStream &source, char criterion)
	Lexing function that reads from the stream while its current char equals the provided one. The read chars are returned. More...
template<typename InputStream >
std::string	read_while (InputStream &source, std::function< bool(char)> criterion)
	Lexing function that reads from the stream while its current char fulfills the provided criterion. The read chars are returned. More...
template<typename InputStream >
void	skip_to_end_of_line (InputStream &source)
	Lexing function that advances the stream to the end of the line, i.e., to the new line char. More...
template<typename InputStream >
void	skip_until (InputStream &source, char criterion)
	Lexing function that advances the stream until its current char equals the provided one. More...
