The export_to_level method looks like: -MyPackage->export_to_level($where_to_export, $package, @what_to_export); + MyPackage->export_to_level($where_to_export, $package, @what_to_export); where $where_to_export is an integer telling how far up the calling stack to export your symbols, and @what_to_export is an array telling what @@ -257,30 +257,30 @@ currently unused. For example, suppose that you have a module, A, which already has an import function: -package A; + package A; -@ISA = qw(Exporter); -@EXPORT_OK = qw ($b); + @ISA = qw(Exporter); + @EXPORT_OK = qw ($b); -sub import -{ - $A::b = 1; # not a very useful import method -} + sub import + { + $A::b = 1; # not a very useful import method + } and you want to Export symbol $A::b back to the module that called package A. Since Exporter relies on the import method to work, via inheritance, as it stands Exporter::import() will never get called. Instead, say the following: -package A; -@ISA = qw(Exporter); -@EXPORT_OK = qw ($b); + package A; + @ISA = qw(Exporter); + @EXPORT_OK = qw ($b); -sub import -{ - $A::b = 1; - A->export_to_level(1, @_); -} + sub import + { + $A::b = 1; + A->export_to_level(1, @_); + } This will export the symbols one level 'above' the current package - ie: to the program or module that used package A. |
