Summary: Mixin template evaluated to string can convert to string mixin expression implicitly Product: D Version: D2 Platform: All OS/Version: All Status: NEW Severity: enhancement Priority: P2 Component: DMD AssignedTo: nob...@puremagic.com ReportedBy: k.hara...@gmail.com --- Comment #0 from Kenji Hara <k.hara...@gmail.com> 2011-06-24 03:48:28 PDT --- If mixin template instantiation makes manifest constant string and it appears in expression context, the compiler converts it implicitly to string mixin expression. This enhancement feature does not conflict with any existing features. Because normal instantiating with mixin template is illegal. Sample code: ---- mixin template expand(string code) { static if (code.length >= 2 && code[0..2] == "$x") { enum expand = `x` ~ code[2..$]; pragma(msg, expand); } else enum expand = code; } void main() { int x = 1; int y = expand!q{$x+2}; // Rhs is implicitly converted to mixin(expand!(q{$x+2})) assert(y == 3); } ---- -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
