No return statment:

$ cat a.d
import std.stdio;

int main() {
        writef("i kupa\n");
}

$ dmd a.d -run
i kupa
Error: AssertError Failure a(5)

Is this bug?


oh, and:
$ dmd -run a.d


suppose ...


Anyway - neat stuff. Time to rewrite some of my daily used scripts. :>

int main() { writef("i kupa\n"); return 0; } left out the return. I've done that. Dawid Ciężarkiewicz wrote:

Sorry, but I don't understand what are you trying to say. :) I know that I've got no return statement, but IMO assert(...) is not right way to communicate that. They are many posts of new users with "DMD's warnings/errors are cryptic" and they are always "where?" replies. "Here". Sorry if I missunderstood your intentions (please be more verbose in such circumstance).

Try compiling with "-w" switch. "warning - test.d(2): function test.main no return at end of function" -- Derek Parnell Melbourne, Australia

It's the compiler that should be more verbose :) Is there a technical difficulty to adding a custom string? Or some reason why a string wouldn't be desirable i.e. performance? binary size/complexity? This ties in with previous requests for custom strings on asserts, is it that there is a problem with doing it, or is it just a low priority feature? The argument against them in the past has been that an assert is a debug tool and if you get one you simply look in the source for the cause of the assert and as such no custom string is required. I think there is some sound reasoning there but I think that the fact that this assert is not visible in the code makes it a good cadidate for a custom string and I suspect that once it was added user defined custom strings for user defined asserts would become a trivial feature to add. I also imagine sending a customer a debug build in order to replicate a fault and debug it, in such a case an assert that could output the data it was asserting on, i.e. assert(i < 10,"i(%d) >= 10",i); would be a valuable debugging tool, no?
