| -- 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 Preelaborate; |
| -- Note that this unit is Preelaborate, but not Pure, that's because the |
| -- functions here such as Line are clearly not pure functions, and normally |
| -- we mark intrinsic functions in a Pure unit as Pure, even though they are |
| -- imported. |
| -- |
| -- Historical note: this used to be Pure, but that was when we marked all |
| -- intrinsics as not Pure, even in Pure units, so no problems arose. |
| |
| function File return String with |
| Import, Convention => Intrinsic; |
| -- 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 with |
| Import, Convention => Intrinsic; |
| -- Return the current input line number. The result is considered to be a |
| -- static expression. |
| |
| function Source_Location return String with |
| Import, Convention => Intrinsic; |
| -- 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 with |
| Import, Convention => Intrinsic; |
| -- 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. |
| |
| function Compilation_ISO_Date return String with |
| Import, Convention => Intrinsic; |
| -- Returns date of compilation as a static string "yyyy-mm-dd". |
| |
| function Compilation_Date return String with |
| Import, Convention => Intrinsic; |
| -- Returns date of compilation as a static string "mmm dd yyyy". This is |
| -- in local time form, and is exactly compatible with C macro __DATE__. |
| |
| function Compilation_Time return String with |
| Import, Convention => Intrinsic; |
| -- Returns GMT time of compilation as a static string "hh:mm:ss". This is |
| -- in local time form, and is exactly compatible with C macro __TIME__. |
