Detailed Description

Interface to the Task module.

Macro Definition Documentation

#define BOOLEAN_TASK_DECLARE	(		Name,
			Help,
			Flag,
			Deps
	)		extern bool Flag;

Instantiate a BooleanTask.

#define CONCAT	(		A,
			B
	)		CONCAT_(A, B)

#define CONCAT_	(		A,
			B
	)		A ## B

A means to concatenate tokens with delayed evaluation.

#define DISJUNCTIVE_TASK_DECLARE	(		Name,
			Help,
			Deps
	)

Instantiate a DisjunctiveTask.

#define INT_TASK_DECLARE	(		Name,
			Min,
			Max,
			Help,
			Flag,
			Deps
	)

Instantiate an IntTask.

#define MULTIPLE_STRING_TASK_DECLARE	(		Name,
			Help,
			Routine,
			Deps
	)		extern void (Routine) (std::string);

Instantiate a MultipleStringTask.

#define STRING_TASK_DECLARE	(		Name,
			Default,
			Help,
			Flag,
			Deps
	)		extern std::string Flag;

Instantiate a StringTask.

#define TASK_DECLARE	(		Name,
			Help,
			Routine,
			Deps
	)		extern void (Routine) ()

Instantiate a FunctionTask.

#define TASK_GROUP

(

Name

)

extern const char* group_name

Define the current Task group name.

#define TASK_UNIQUE

(

)

CONCAT(task_, __LINE__)

Make a "unique" token using the line number of invocation of this macro.

Conflicts are possible, but unlikely: tasks declared at the same line number, but in different files, are not a problem, since anyway the tasks are static, and in different namespaces.

Just don't declare two tasks on the same line!
