July 15, 2017 Add property setting to chain | ||||
---|---|---|---|---|
| ||||
Let i have code: Clock.currTime.to!DateTime.Interval!DateTime( 24.hours ).fwdRange( h=>h+1.hours ).writeln; Now if i want to set the minute=0 and second=0 without breaking chain, what i should do? I think about somewhat like: with( Clock.currTime.to!DateTime){ minute=0; second=0 }.Interval!DateTime( 24.hours ).fwdRange( h=>h+1.hours ).writeln; But it is wrong, because 'with' not return me anything. |

Posted in reply to closescreen | I found this solution: Clock.currTime.to!DateTime.pipe!( dt=>(dt.minute=0,dt.second=0, dt) ).Interval!DateTime( 24.hours ).fwdRange( h=>h+1.hours ).writeln; Or: Clock.currTime.to!DateTime.pipe!( "a.minute=0, a.second=0, a" ).Interval!DateTime( 24.hours ).fwdRange( h=>h+1.hours ).writeln; Is this code looks good, idiomatic? |

I would probably write a function: import std.datetime; import std.stdio; import std.range; import std.conv; DateTime hourPrecision(DateTime dt) { dt.minute = 0; dt.second = 0; return dt; } void main() { Clock.currTime.to!DateTime.hourPrecision.Interval!DateTime( 24.hours ).fwdRange( h=>h+1.hours ).writeln; } Ali |
