Hi guys.  I'm playing with D at the moment, it's quite nice.  I'm checking out properties, ie..
class Mytest
{
	int tmp;
	
	void tp(int newTmp) { printf("assigning tmp\n"); tmp =newTmp;};
	int tp() { printf("getting tmp\n"); return tmp;};
}

but DLI gives me the following errors
test.d(48): Error: cannot implicitly convert int to void(int newTmp)
test.d(49): Error: cannot implicitly convert void(int newTmp) to int

Is this a problem in my code, lack of implementation in Walter's frontend or a missing section in DLI?
If it is a DLI issue could someone point me to a place to look to implement it?

Cheers
Brad

Does your class really look like that?
haven't you forgotten a little thing?
did you try to compile the piece you're sending?
here the identifiers simply don't match. i've marked them below.

Properties support is in the very latest version (http://www.opend.org/dli/arc/dli-0.1.2.tar.gz).  I see that the menu bar on OpenD is still linking to 0.1.1, I'll have to fix that.

That's what I originally thought too, but according to the sample code in the D spec...

class Abc
	{	int myprop;
		void property(int newproperty) { myprop = newproperty; } // set'er
		int property() { return myprop; }	// get'er
	}

Personally I'd like to keep the property & it's setters/getters similar, but still different.  If they're difference then I can more clearly know what I am trying to do - ie am I try to access the var directly, or though the property methods - I don't want the variable to exactly shadow the getters/settors.

I suspect I will take a code style where my internal variables that are accessed through setters/getters have some kind of pre or postfix - ie
_property or somesuch.


Cheers
Brad

Damnit, i was looking at the very same piece of code in the manual, and didn't notice the identifiers here are different too... I guess i need to force myself to sleep more. sorry for misleading.
