Macros and exceptions

Detailed Description

Foundational macros, exception types and compiler/platform glue.

Classes
class	triqs::exception
	Base class for exceptions thrown in TRIQS. More...
class	triqs::keyboard_interrupt
	Exception raised when the user interrupts the program with Ctrl-C. More...
class	triqs::runtime_error
	Generic runtime error thrown in TRIQS. More...

Macros
#define	TRIQS_CONCAT(X1, X2)
	Concatenate two tokens, expanding them first if they are macros.
#define	TRIQS_FORTRAN_MANGLING(id)
	Translate the C++ identifier id to the corresponding Fortran symbol name.
#define	TRIQS_CONCEPT_TAG_NAME(MyBeautifulConcept)
	Helper macro that produces the name of the tag for TRIQS_DEFINE_CONCEPT_AND_ASSOCIATED_TRAIT.
#define	TRIQS_DEFINE_CONCEPT_AND_ASSOCIATED_TRAIT(MyBeautifulConcept)
	Define a tag-based pseudo-concept.
#define	TRIQS_DEFINE_CONCEPT_AND_ASSOCIATED_TRAIT_R_AUX(r, data, i, elem)
	Helper used by TRIQS_DEFINE_CONCEPT_AND_ASSOCIATED_TRAIT_R.
#define	TRIQS_DEFINE_CONCEPT_AND_ASSOCIATED_TRAIT_R(MyBeautifulConcept, Rs)
	Define a tag-based pseudo-concept with refinements.
#define	TRIQS_ERROR(CLASS, NAME)
	Throw an exception of type CLASS whose message starts with Triqs <NAME> and the current source location.
#define	TRIQS_RUNTIME_ERROR   TRIQS_ERROR(triqs::runtime_error, "runtime error")
	Throw a triqs::runtime_error with the current source location.
#define	TRIQS_KEYBOARD_INTERRUPT   TRIQS_ERROR(triqs::keyboard_interrupt, "Ctrl-C")
	Throw a triqs::keyboard_interrupt with the current source location.
#define	TRIQS_ASSERT(X)
	Throw a triqs::runtime_error if the boolean expression X evaluates to false.
#define	TRIQS_ASSERT2(X, ...)
	Like TRIQS_ASSERT but lets the caller add a custom message.
#define	DECL_AND_RETURN(...)
	Trailing-return-type convenience: expands to -> decltype(...) { return ...; }.
#define	TRIQS_CATCH_AND_ABORT
	Macro to catch exceptions, print the error message and return 1.
#define	TRIQS_DEPRECATED(Message)
	Mark a function or type as deprecated with a custom message.
#define	TRIQS_PRINT(X)
	Macro that prints the name and value of a variable together with the source location.
#define	FORCEINLINE   __inline__ __attribute__((always_inline))
	Force-inline attribute portable across GCC and Clang.
#define	TERMINATE(X)
	Macro that prints a message together with the source location and calls std::terminate().

TRIQS_DEFINE_CONCEPT_AND_ASSOCIATED_TRAIT

#define TRIQS_DEFINE_CONCEPT_AND_ASSOCIATED_TRAIT

(

MyBeautifulConcept

)

#include <triqs/utility/concept_tools.hpp>

Value:

  struct TRIQS_CONCEPT_TAG_NAME(MyBeautifulConcept) {};                                                                                              \

  template <typename T> struct MyBeautifulConcept<const T> : MyBeautifulConcept<T> {};                                                               \

  constexpr bool MyBeautifulConcept##_v = std::is_base_of<TRIQS_CONCEPT_TAG_NAME(MyBeautifulConcept), typename std::decay<T>::type>::value;

Define a tag-based pseudo-concept.

It does the following:

• Defines an empty tag struct using TRIQS_CONCEPT_TAG_NAME.
• Defines a class template MyBeautifulConcept<T> derived from std::is_base_of<tag, T> and partial specializations that strip cv- and reference-qualifiers.
• Defines a variable template MyBeautifulConcept_v<T> that evaluates to true if T inherits from the tag.
