September 04, 2019 D1: How to declare an Associative array with data | ||||
---|---|---|---|---|
| ||||
Yes, I know. I am using D1, and I love it. ;-) Greetings. I know that I can declare an array with data, ie. string[] d = ["1","2","three","4]; and this will be done at compiled time. I want to do the same with an associative array., ie. int[string] MyDigits = ["0" = 0, "1" = 1, "2" = 2]; That does not work. I also tried, int[string] MyDigits = ["0" : 0, "1" : 1, "2" : 2]; Nope, it does not work either. Any thoughts? thanks. josé |

I want to do the same with an associative array., ie. That's actually only at compile time if it is in static scope, if it inside a function, it is a runtime array. But anyway.. > int[string] MyDigits = ["0" : 0, "1" : 1, "2" : 2]; > > Nope, it does not work either. Any thoughts? thanks. this works at runtime inside a function, but does not work at compile time at all, in any version of D (as of right now); the compile-time AA to static data was never implemented. You could possibly do a custom implementation though. |

Darn it! I tried to see if I could get it set at compiled time. Thanks, and thanks for your wonderful knowledge and gift to D. Big fan of your work. Thanks. josé |
