These subprograms are -- intrinsic operations that provide information known to the compiler in -- a form that can be embedded into the source program for identification -- and logging purposes. For example, an exception handler can print out -- the name of the source file in which the exception is handled. package GNAT.Source_Info is pragma Pure; function File return String; -- Return the name of the current file, not including the path information. -- The result is considered to be a static string constant. function Line return Positive; -- Return the current input line number. The result is considered to be a -- static expression. function Source_Location return String; -- Return a string literal of the form "name:line", where name is the -- current source file name without path information, and line is the -- current line number. In the event that instantiations are involved, -- additional suffixes of the same form are appended after the separating -- string " instantiated at ". The result is considered to be a static -- string constant. function Enclosing_Entity return String; -- Return the name of the current subprogram, package, task, entry or -- protected subprogram. The string is in exactly the form used for the -- declaration of the entity (casing and encoding conventions), and is -- considered to be a static string constant. The name is fully qualified -- using periods where possible (this is not always possible, notably in -- the case of entities appearing in unnamed block statements.) -- -- Note: if this function is used at the outer level of a generic package, -- the string returned will be the name of the instance, not the generic -- package itself. This is useful in identifying and logging information -- from within generic templates. private pragma Import (Intrinsic, File); pragma Import (Intrinsic, Line); pragma Import (Intrinsic, Source_Location); pragma Import (Intrinsic, Enclosing_Entity); end GNAT.Source_Info;
