http://d.puremagic.com/issues/show_bug.cgi?id=11008 Summary: Allow -main switch even if user-defined main function exists Product: D Version: D2 Platform: All OS/Version: All Status: NEW Severity: enhancement Priority: P2 Component: DMD AssignedTo: nobody puremagic.com ReportedBy: k.hara.pg gmail.com Currently, if user-defined main() function exists, specifying -main switch will fail to compile. // test.d void main() {} $ dmd -main -run test test.d(1): Error: only one main/WinMain/DllMain allowed, -main switch added another main() But I think this is unnecessary restriction. Compiler can stop adding "another main" when user-defined main() detected. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------

Giving the user an error alerts them to the fact that they're trying to add a main when there already is one (one which almost certainly doesn't do what they want). So, it seems to me that not having -main error out gains us little and causes problems when someone tries to use -main when they already have a main function defined. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------

That way you'd be be able to run the unittests without executing anything else? -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
