fe Namespace Reference

Namespaces
namespace	format
namespace	utf8

Classes
class	Arena
	An arena pre-allocates so-called pages of size Arena::page_size_. More...
struct	basic_ostream_formatter
	Make types that support ostream operators available for std::format. More...
struct	Driver
	Use/derive from this class for "global" variables that you need all over the place. More...
class	Lexer
	The blueprint for a lexer with a buffer of K tokens to peek into the future (Lexer::ahead). More...
struct	Loc
	Location in a File. More...
class	Parser
	The blueprint for a recursive descent/ ascent parser using a K lookahead of Tokens. More...
struct	Pos
	Position in a source file; pass around as value. More...
class	Ring
	A ring buffer with N elements. More...
class	Ring< T, 1 >
	Specialization if N == 1 - doesn't need a ring. More...
class	Ring< T, 2 >
	Specialization if N == 2; doesn't need a ring, we just copy. More...
class	RuntimeCast
	Inherit from this class using CRTP, for some nice dynamic_cast-style wrappers. More...
class	Sym
	A Symbol just wraps a pointer to Sym::String, so pass Sym itself around as value. More...
class	SymPool
	Hash set where all strings - wrapped in Symbol - live in. More...
class	Tab
	Keeps track of indentation level during output. More...

Concepts
concept	Nodeable

Typedefs
using	ostream_formatter = basic_ostream_formatter< char >
Sym
Set/Map is keyed by pointer - which is hashed in SymPool.
template<class V >
using	SymMap = std::unordered_map< Sym, V >
using	SymSet = std::unordered_set< Sym >

Functions
void	unreachable ()
void	breakpoint ()
	Raise breaokpoint in debugger.
std::ostream &	operator<< (std::ostream &os, Pos pos)
std::ostream &	operator<< (std::ostream &os, Loc loc)
out/outln/err/errln
Print to std::cout/std::cerr via std::format; the *ln variants conclude with std::endl.
