Summary: Infinite foreach on array Product: D Version: D2 Platform: x86 OS/Version: Windows Status: NEW Severity: enhancement Priority: P2 Component: DMD AssignedTo: nob...@puremagic.com ReportedBy: bearophile_h...@eml.cc --- Comment #0 from bearophile_h...@eml.cc 2011-11-29 19:11:45 PST --- Maybe this issues is already present in Bugzilla. I'd like this code to loop on all array 256 items once, initialize the array with all the bytes starting from the larger one, and then stop, but it goes into infinite loop: void main() { ubyte[256] table; foreach (ubyte i, ref x; table) x = 255 - i; } But Jonathan M Davis suggests that 'i' should always be size_t if it's an index: http://www.digitalmars.com/webnews/newsgroups.php?art_group=digitalmars.D.learn&article_id=30863 This means Jonathan M Davis suggests to turn that code in a compilation error, so the right code become something like (the & is needed because currently D2 can't infer that 255-i fits in one ubyte): void main() { ubyte[256] table; foreach (i, ref x; table) x = (255 - i) & ubyte.max; } In any case, regardless of the solution that will be chosen (make it do the 'right' thing, or statically forbid that code requiring the index to be a size_t, or yet another solution), I suggest to not leave such trap in D2. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
