Re: Can someone explain how glfw3.dll gets created?
On 10/14/2014 5:21 AM, WhatMeWorry wrote: I have a simple GLFW3 program running in Visual D integrated shell, that kept aborting at DerelictFLFW3.load() with a failed to load the shared libraries: glfw3.dll.' So I found a glfw3.dll somewhere and moved it into the project folder (I know this is bad technique) and that fixed the problem. But now I'm wondering were this glfw3.dll came from. Others have already answered your specific question, but I would just like to point out that their answers are generally true for any Derelict package you use. Derelict binds to C libraries, or C++ libraries with C interfaces, so that they are usable from D. When you add Derelict to your dub configuration, or in your Visual D build settings, all you are getting are the D files allow you to interface with the C libraries -- you are not getting the C libraries themselves. On Windows, in most cases you have to go out and either download a prebuilt binary or download and compile the C source yourself. I say /most cases/ because OpenGL will already be on your system as part of your graphics driver and you may already have another library or two installed in your system directories (like OpenAL, perhaps). Furthermore, Derelict is a /dynamic/ binding in that it loads the shared libraries at runtime and has absolutely no compile time dependency on any of them. This is why you have to call DerelictFoo.load(). That looks for the library on the system path and, if found, loads it into memory so that you can start calling into it. So if you are going to use GLFW, SDL, or anything else, you need to go to that project's web site and use their documentation to understand how to build (if they don't provide binaries) and use those libraries, then make sure that the compiled DLLs are on the system path (meaning, usually, in the executable's directory). --- This email is free from viruses and malware because avast!

When betterC triggers errors in compilation?
Hello,
According to this:
http://forum.dlang.org/post/lddug4$jgv$1...@digitalmars.com
-betterC should disable support for exception handling. So I
expected dmd to reject the following code:
===
import std.stdio;
int readDieFromFile()
{
auto file = File(the_file_that_contains_the_value, r);
int die;
file.readf( %s, die);
return die;
}
int tryReadingFromFile()
{
int die;
try {
die = readDieFromFile();
} catch (std.exception.ErrnoException exc) {
writeln((Could not read from file; assuming 1));
die = 1;
}
return die;
}
void main()
{
const int die = tryReadingFromFile();
writeln(Die value: , die);
}
===
(from Ali's book; thanks once again)
But it compiles and runs fine:
$dmd betterC.d -betterC
$./betterC
(Could not read from file; assuming 1)
Die value: 1
This is with dmd 2.066 on Linux x86_64.
What code would fail under -betterC and how?

(And I think that went way too far, IMO betterC should just remove the mandatory stuff like ModuleInfo and TypeInfo assumptions and leave the rest to be opt in. I'd be against it making exception handling an error). -betterC right now is still an undocumented hack that doesn't do much.

Mixin template functions are ignored in struct
I have written a struct and a mixin template, and that mixin
template is mixed into that struct as follows.
private mixin template TestCommonMethods(){
public bool apply( int d, int e ){
return false;
}
}
public struct Test{
public mixin TestCommonMethods;
public bool apply( char c ){
return true;
}
}
void main(){
Test t;
t.apply( 5, 3 );
}
---
For the line t.apply( 5, 3 );, error is given saying that
function test.apply(char c) is not callable.
---
For better testing, I added another function to template as
public bool blah(){}, and called it in main, and it works. So,
thus this mean overloading is not supported with mixin templates?

http://dlang.org/template-mixin.html says:
If the name of a declaration in a mixin is the same as a
declaration in the surrounding scope, the surrounding

So, yes, the mixed in `apply` doesn't overload with the other one.
You can use an alias declaration to bring them together:
public struct Test{
public mixin TestCommonMethods Common;
alias apply = Common.apply;
public bool apply( char c ){
return true;
}
}

Hmm, so it is not able to mix enough then. That's a weird
decision though. Anyway, that suggested usage is making my work
harder. I am putting that mixin in many struct and defining each
method one by one in that way doesn't seem like suitable to me.
Re: Mixin template functions are ignored in struct
On Tuesday, 14 October 2014 at 20:58:19 UTC, tcak wrote: So, thus this mean overloading is not supported with mixin templates? Nope, what happens is mixin stuff adds items by name. If you have a variable or function in the object with the same name, it overrides the mixin one entirely. This is really useful for customizing the behavior of a mixin by taking most but not all of its functions.

You could rename the method in the struct then mixin the rest.
Like
private mixin template TestCommonMethods(){
public bool apply( int d, int e ){
return false;
}
}
public struct Test{
public mixin TestCommonMethods;
public bool apply2( char c ){ // now named apply2
return true;
}
}
void main(){
Test t;
t.apply( 5, 3 ); // works
t.apply2('c'); // also works
}
The mixin template might also define an apply function that just
forwards the call to the other name, similarly to how a final
method in a class or interface might call a virtual function to
allow customization.
