https://d.puremagic.com/issues/show_bug.cgi?id=11847 Summary: Importing "package.d" module causes qualified name lookup to fail for sub modules Product: D Version: D2 Platform: All OS/Version: All Status: NEW Severity: major Priority: P2 Component: DMD AssignedTo: nobody puremagic.com ReportedBy: sludwig outerproduct.org PST --- The following errors out with "main.d(5): Error: undefined identifier 'mod'": main.d --- import test; import test.mod; void main() { test.mod.func(); } --- test/package.d --- module test; --- test/mod.d --- module test.mod; void func() {} --- Seems like ".test" now refers to the module instead of the package and thus there is no sub module "mod". Tested on DMD 2.064.2. -- Configure issuemail: https://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------

https://d.puremagic.com/issues/show_bug.cgi?id=11847The following errors out with "main.d(5): Error: undefined identifier 'mod'": main.d --- import test; import test.mod; void main() { test.mod.func(); } ---Currently this is by design. If you use fully qualified name that starts with "test.", test/package.d is always preferred to avoid ambiguity. -- Configure issuemail: https://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------

https://d.puremagic.com/issues/show_bug.cgi?id=11847So how would I specify a qualified name in test.mod?There's no way, if you import both test/package.d and test/mod.d. I think it is legitimate limitation of the new package.d feature. -- Configure issuemail: https://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------

https://d.puremagic.com/issues/show_bug.cgi?id=11847 PST --- I think this is actually totally unacceptable and a *serious* design flaw. What this means is that it is now impossible to reference any sub module of "test" as soon as "test" is imported. This seems to be based on the assumption that "package.d" modules always import all modules of their package, which is just wrong. There are many possible reasons why it would exclude certain modules. This also means that it is now impossible to disambiguate conflicting symbols when one of them is in such a sub module. This completely breaks the module system. A real world example, where it is important to be able to handle this cleanly, is an automatically generated function that iterates over all modules of a project (It's a unit test runner that runs all unit tests for each module). It contains code similar this: --- static import test; static import test.mod; alias AllModules = TypeTuple!(test, test.mod); // error main() { foreach (mod; AllModules) ... } --- The only half reasonable thing that could be done there is to generally ignore all "package.d" modules. And that is based on the assumption that "package.d" modules *only* import all sub modules and have no own declarations, which, in general, again is wrong. Also, if there is no NG or conference discussion that I didn't see, there is no sign in the original DIP that this issue was even considered before implementing it. In this case, calling it by design may be a slight exaggeration. -- Configure issuemail: https://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
