First use case: the package does not use OO <pre> namespace eval ::N1 { proc m1 {} {msgcat::mcpackagenamespaceget} } % N1::m1 -> ::N1 </pre> 2. Second use case: call within class definition script <pre> % namespace eval ::N2Class { oo::class create C1 {puts "pns=[msgcat::mcpackagenamespaceget]"} } -> pns=::N2Class -> ::N2Class::C1 </pre> 3. Third use case: The package implementation is done by a class <pre> namespace eval ::N3Class { oo::class create C1 oo::define C1 method m1 {msgcat::mcpackagenamespaceget} } # The class object may be used in another namespace namespace eval ::N3Obj { set O1 [::N3Class::C1 new] } % $N3Obj::O1 m1 -> ::N3Class </pre> 4. Fourth use case: The package implementation is done by a classless object <pre> namespace eval ::N4 { oo::object create O1 oo::objdefine O1 method m1 {} {msgcat::mcpackagenamespaceget} } % N4::O1 m1 -> ::N4 </pre> ### Manually overwriting the package namespace by namespace eval As stated in the introduction, current OO code might have used an explicit `namespace eval packagenamespace` to make msgcat work. This should still be supported: <pre> namespace eval ::N4 { oo::object create O1 oo::objdefine O1 method m1 {} { namespace eval ::N5 { msgcat::mcpackagenamespaceget} } |
