-- This package provides some useful utility subprograms that provide access
-- to source code information known at compile time. 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 (Source_Info);
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.
--
-- 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.
