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.
