https://d.puremagic.com/issues/show_bug.cgi?id=12067 Summary: std.datetime.measureTime() has incomplete example, and does not work Product: D Version: D2 Platform: All OS/Version: All Status: NEW Severity: normal Priority: P2 Component: Phobos AssignedTo: nobody puremagic.com ReportedBy: bugzilla digitalmars.com 20:59:43 PST --- is supposed to be for measuring the elapsed time of some code, i.e. for benchmarking it. But: 1. The example given is a code fragment, the user is left to guess what else might be needed to get it to work. 2. The user most likely wants to print the elapsed time. The example gives no clue how to do that. 3. Guessing at what is needed to make a complete program, the program fails to link: ----------------------------- import std.datetime; import std.stdio; void main() { writeln("benchmark start!"); { auto mt = measureTime!((a){assert(a.seconds);}); doSomething(); } writeln("benchmark end!"); } ------------------------------ C:\mars>\dmd2\windows\bin\dmd foo OPTLINK (R) for Win32 Release 8.00.13 Copyright (C) Digital Mars 1989-2010 All rights reserved. http://www.digitalmars.com/ctg/optlink.html foo.obj(foo) Error 42: Symbol Undefined _D3foo4mainFZv46__T14__funcliteral1TS4core4time12TickDurationZ14__funcli teral1FS4core4time12TickDurationZv --- errorlevel 1 -- Configure issuemail: https://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------

Note that the measureTime examples do not use documented unittest blocks, because that doesn't work when the documentation is split out into a separate version(StdDDoc) section. https://github.com/D-Programming-Language/phobos/commit/ef000e8150ffaf0030ea5c62c311a23e5067d139 Fix issue 12067. -- Configure issuemail: https://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
