| 32 -- This package provides some useful utility subprograms that provide access | |
| 33 -- to source code information known at compile time. These subprograms are | |
| 34 -- intrinsic operations that provide information known to the compiler in | |
| 35 -- a form that can be embedded into the source program for identification | |
| 36 -- and logging purposes. For example, an exception handler can print out | |
| 37 -- the name of the source file in which the exception is handled. | |
| 38 | |
| 39 package GNAT.Source_Info is | |
| 40 pragma Preelaborate; | |
| 41 -- Note that this unit is Preelaborate, but not Pure, that's because the | |
| 42 -- functions here such as Line are clearly not pure functions, and normally | |
| 43 -- we mark intrinsic functions in a Pure unit as Pure, even though they are | |
| 44 -- imported. | |
| 45 -- | |
| 46 -- Historical note: this used to be Pure, but that was when we marked all | |
| 47 -- intrinsics as not Pure, even in Pure units, so no problems arose. | |
| 48 | |
| 49 function File return String with | |
| 50 Import, Convention => Intrinsic; | |
| 51 -- Return the name of the current file, not including the path information. | |
| 52 -- The result is considered to be a static string constant. | |
| 53 | |
| 54 function Line return Positive with | |
| 55 Import, Convention => Intrinsic; | |
| 56 -- Return the current input line number. The result is considered to be a | |
| 57 -- static expression. | |
| 58 | |
| 59 function Source_Location return String with | |
| 60 Import, Convention => Intrinsic; | |
| 61 -- Return a string literal of the form "name:line", where name is the | |
| 62 -- current source file name without path information, and line is the | |
| 63 -- current line number. In the event that instantiations are involved, | |
| 64 -- additional suffixes of the same form are appended after the separating | |
| 65 -- string " instantiated at ". The result is considered to be a static | |
| 66 -- string constant. | |
| 67 | |
| 68 function Enclosing_Entity return String with | |
| 69 Import, Convention => Intrinsic; | |
| 70 -- Return the name of the current subprogram, package, task, entry or | |
| 71 -- protected subprogram. The string is in exactly the form used for the | |
| 72 -- declaration of the entity (casing and encoding conventions), and is | |
| 73 -- considered to be a static string constant. The name is fully qualified | |
| 74 -- using periods where possible (this is not always possible, notably in | |
| 75 -- the case of entities appearing in unnamed block statements.) | |
| 76 -- | |
| 77 -- Note: if this function is used at the outer level of a generic package, | |
| 78 -- the string returned will be the name of the instance, not the generic | |
| 79 -- package itself. This is useful in identifying and logging information | |
| 80 -- from within generic templates. | |
| 81 | |
| 82 function Compilation_ISO_Date return String with | |
| 83 Import, Convention => Intrinsic; | |
| 84 -- Returns date of compilation as a static string "yyyy-mm-dd". | |
| 85 | |
| 86 function Compilation_Date return String with | |
| 87 Import, Convention => Intrinsic; | |
| 88 -- Returns date of compilation as a static string "mmm dd yyyy". This is | |
| 89 -- in local time form, and is exactly compatible with C macro __DATE__. | |
| 90 | |
| 91 function Compilation_Time return String with | |
| 92 Import, Convention => Intrinsic; | |
| 93 -- Returns GMT time of compilation as a static string "hh:mm:ss". This is | |
| 94 -- in local time form, and is exactly compatible with C macro __TIME__. | |
