Contracts for interfaces and abstract classes

2012-08-20 Thread Mike L.
I'm on ubuntu x64 using dmd 2.060 and the following gives an exception: rdmd --main -unittest -version=useInterface mml/sets.d while the following runs just fine: rdmd --main -unittest -version=useAbstractClass mml/sets.d The exception is: object.Exception@src/object_.d(108): need opCmp for

Sorry, the title of the thread might be irrelevant, it's just that I was playing around with contracts when I noticed the problem.

Re: foreach for ranges?

2012-07-18 Thread Mike L.
Also, UFCS makes no sense on overloaded operators, because they don't get called with ., and all UFCS is is changing obj.func(params) to func(obj, params). - Jonathan M Davis Ok, that's basically what I was wondering. I had assumed foreach(e; someThing) {} could possibly have been converted

foreach for ranges?

2012-07-17 Thread Mike L.
How exactly does the compiler know how to do foreach on ranges (for example, ones returned by std.algorithm.map ?) I've looked around in std.algorithm and std.range, but can't seem to figure it out.

Tempated class instantiation

2009-12-15 Thread Mike L.
I'm making a class template that only works with strings, so I thought it'd be good to instantiate each template with char, wchar, and dchar right in the template's module so that when it's compiled it'll be part of the .obj file and won't have to compile it for every other project that uses

Apparently I'm missing some basic concept about how D does OO since I recreated the problem with a simpler function. I'll re-examine things...

Thanks, glad to have it all in one place.

Constants?

2009-02-11 Thread Mike L.
Could someone lay out for me the different ways of doing constants in D (d1, particularly)? I've heard things about const, final, invariant, and anonymous enums?

I saved and compiled the code given as getenv.d on the page http://www.digitalmars.com/d/archives/digitalmars/D/learn/623.html but I'm not entirely sure why it works. The reasons that I don't understand it are: 1. GetEnvironmentStringsA() and the other functions aren't mentioned in
