| -- 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. |
