Summary: Allow passing arguments to templates in CTFE Product: D Version: D2 Platform: All OS/Version: All Status: NEW Severity: enhancement Priority: P2 Component: DMD AssignedTo: nob...@puremagic.com ReportedBy: jens.k.muel...@gmx.de --- Comment #0 from jens.k.muel...@gmx.de 2012-09-23 13:47:19 PDT --- When doing CTFE it may be worthwhile to allow passing of function arguments to template instantiations. This eases better integration between templates and CTFE making meta programming more convenient. Example: bool foo(string a) { return bar!(a); } template bar(string b) { enum bar = true; } fails to compile with test.d(3): Error: variable a cannot be read at compile time The problem is that foo must be compilable to be executed at run-time which clearly cannot work with the above code. But if __ctfe was a compile-time known value foo could be written like: static if (__ctfe) { return bar!(a) } else { return false; } -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
