If you just fix the second part (that you can now retrieve all members of std), doesn't it fix the problem? -Steve Main problem is that allMembers returns strings and you can't tell if member is an import from it. If it returned aliases then you could do is(m == module), etc.

One unfortunate sideeffect of allMembers change is that it breaks
this king of loop:
```
foreach(m; __traits(allMembers, M)) { // M is module
alias member = __traits(getMember, M, m); // now fails
because std.stdio is not a member of M
}
```
To fix I needed to rewrite it as:
```
foreach(m; __traits(allMembers, M)) { // M is module
static if (__traits(compiles, __traits(getMember, M, m)))
alias member = __traits(getMember, M, m);
}
```

I'm annoyed with C++ includes and I'm tired to create 2 files every time when I need to add something new to the project... But I must admit that one thing I like in header files is that it is a convenient way to read public interfaces. In D we have interface specification and implementation in a single file and also one approach with unit testing is to put them immediately after functions which makes writing unit tests even more easy task (and I like it very much) but again it makes the gaps between declarations even wider. So, what are the common approaches for reading public interfaces in D programs? Especially it would be great to see the answers of developers who work with more or less big codebases. The few possible solution I'm thinking about at the moment: a) Provide D interfaces for corresponding classes (but probably it's only for more or less complex abstractions and also I won't use it for Vector3D, also very often I use just regular functions). b) Write DDocs and read documentation. The problem here is that I'm going to use D only for my own projects and in the last time I tend to write less documentation, for example I do not write it for the most methods of Vector3D. c) Do nothing special, just write D modules and try to figure out public interfaces reading its code. Maybe it works in practice. Thanks, Artem. You can also fold all the function bodies in your editor, this helps me to read massive sources.

Note that this is still in a very early stage, it was put together in a very quick-and-dirty style by a person with little webdev experience. Currently it just scans `code.dlang.org`, looking for changes (yes, I know, this will break as soon as code.dlang.org changes, I plan to raise issue/s (PRs?) to the dub registry project so it can have a full/stable API, but I wanted to get something to work *right now*.

That is pretty cool! I will put a link to it in all my project readmes. I've noticed that License: a$(WEB boost.org/LICENSE_1_0.txt, Boost License 1.0). gets rendered as a. Am I doing it wrong?

There is a comparison to msgpack here (and to other formats too): http://tools.ietf.org/html/rfc7049#appendix-E.2 which states: [MessagePack] is a concise, widely implemented counted binary serialization format, similar in many properties to CBOR, although somewhat less regular. While the data model can be used to represent JSON data, MessagePack has also been used in many remote procedure call (RPC) applications and for long-term storage of data. MessagePack has been essentially stable since it was first published around 2011; it has not yet had a transition. The evolution of MessagePack is impeded by an imperative to maintain complete backwards compatibility with existing stored data, while only few bytecodes are still available for extension. Repeated requests over the years from the MessagePack user community to separate out binary text strings in the encoding recently have led to an extension proposal that would leave MessagePack's raw data ambiguous between its usages for binary and text data. The extension mechanism for MessagePack remains unclear.

Here is more info about format: http://cbor.io/
You can easily encode and decode things like built-in types,
arrays, hash-maps, structs, tuples, classes, strings and raw
arrays (ubyte[]).
Here is some simple code:
import cbor;
struct Inner
{
int[] array;
string someText;
}
struct Test
{
ubyte b;
short s;
uint i;
long l;
float f;
double d;
ubyte[] arr;
string str;
Inner inner;
void fun(){} // not encoded
void* pointer; // not encoded
int* numPointer; // not encoded
}
ubyte[1024] buffer;
size_t encodedSize;
Test test = Test(42, -120, 11, -123456789, 0.1234,
-0.987654,
cast(ubyte[])[1,2,3,4,5,6,7,8], It is a test string,
Inner([1,2,3,4,5], Test of inner struct));
encodedSize = encodeCborArray(buffer[], test);
// ubyte[] and string types are slices of input ubyte[].

The different DLLs have different copies of the RTTI for the

pointers, so it doesn't find the target class of a cast in the
hierarchy inside another DLL.

Another workaround for a limited number of classes would be to
add member functions 'ISharedModule1 toSharedModule1() { return
null; }' in IModule and override these 'ISharedModule1
toSharedModule1() { return this; }' in the appropriate class.
Another, and more major issue is, that when exception is thrown

I haven't tried in a while but I think it should work on Win32,
but probably does not on Win64.
I thought it will work at least for interfaces.
Any way, this is workaroundable, but exceptions must be there at
least.

Making plugin system with shared libraries. Upcast in shared lib
I'm using Windows.
I was making some sort of modular system where you can define
modules that are loaded by host application.
Here is a simple example
https://gist.github.com/MrSmith33/7692328455a19e820a7c
Now i want to separate these modules in separate shared libs
and link them on the fly.
The issue i have is that some modules can define some useful
functions and in order to use them you need to upcast to concrete
type. This is easy in a single application, but i was unable to
do this through dll boundary.
So basically all dll's have factory function that returns an
instance of IModule.
Than any module can search for registered modules and try to cast
them to concrete type (upcast).

override string name() {return Module2;}
override void init(ModuleManager modman){}
void someMethod2(){}
}
And what files should i compile with what packages?
application
IModule
main
other
module1 dll
IModule
Module1
Module2 - should i import it, compile of import .di file?
module2 dll
IModule
Module2
Is it possible at all? Or it is an issue with Windows shared lib
support?
Re: Trying to get Derelict.opengl3.gl3 and derelict.glfw3.glfw3 to work together

The gl3 module only declares and loads modern OpenGL. If you really want to use the deprecated stuff, change the gl3 import to this: import derelict.opengl3.gl; And call load/reload on the DerelictGL instance rather than DerelictGL3. All of the modern stuff will still be available. Thanks for this. Was using GLFW's example trying to troubleshoot it. Wasn't really considering them using the outdated functions. I guess I'll look for a different tutorial elsewhere. Also, thanks for making it in the first place! We have opengl tutorials in D https://github.com/d-gamedev-team/opengl-tutorials
Extracting string parameter from template instance received via alias parameter
Given the following program:
-
import std.stdio;
template first(string s)
{
string first(string par)
{
if (par == s)
return true;
else
return false;
}
}
template second(alias firstInstance)
{
string second(string par)
{
// this line doesn't work
static if (is(firstInstance : F!(str), alias F, string str))
{
writeln(matched , str);
}
enum s = XXX; // get s from firstInstance
// without parsing strings and using mixins
// something like second(alias C : F!(str), alias F, string str)
import std.string : icmp;
if (icmp(par, s) == 0)
return true;
else
return false;
}
}
void main()
{
writeln(first!str(str));
writeln(second!( first!str )(StR)); // should match string
from first, but case insensetive
}
-
How do I extract s parameter of first passed to second via alias
parameter. It seems like it is not possible. Or is it?

Thank you, Ali. I will try to not mismatch open tabs next time =)

Re: Using input ranges with std.regex?

For now, yes you have to convert them. Any random access range of code units should do the trick but stringish template constraints might kill that. I plan to extend this eventually. The problematic point is that match internally is delimited by integer offsets (indices). Forward ranges technically can work (the match then will return something like take(..., n);) with a bunch of extra .save calls. Input ranges can't be used at all. Is there any progress on this thing?

Re: bgfx bindings
On Tuesday, 1 July 2014 at 20:43:27 UTC, ponce wrote: Hi, I'd like to announce DerelictBgfx, a dynamic bindings to the bgfx library. https://github.com/derelictorg/derelictbgfx bgfx is a library which abstract the accelerated graphics API through a common denominator. DX9, DX11, Desktop OpenGL and OpenGL ES can be used from the same abstraction. I believe it to be useful and risk-mitigating for games. To allows this feat, a shader language and compiler is included in the original library there: https://github.com/bkaradzic/bgfx Using the derelict-bgfx package, you would have to build bgfx as a dynamic library and the associated shader compiler. bgfx is decoupled from the windowing library. It can be used through the likes of SDL and GLFW, provided a OS-dependent window handle is given. That is awesome!

Re: delegate issue

hi,
i stumbled upon something weird - it looks like a bug to me but
maybe it is a feature that is unclear to me.
so i know i can declare function and delegate pointers at
module level.
for function pointers, i can initialize with a lambda.
BUT for delegates i get an error - see below
i found out that using module static this(){...} provides a
workaround, but why is this necessary?
also, if there is a good reason after all then the error
message should make more sense.
/det
ps: i know there is a shorthand syntax for this.
module demo;
int function(int) fn = function int(int){ return 42; };
// ok
int delegate(int) dg = delegate int(int){ return 666; };
// demo.d(6): Error: non-constant nested delegate literal

void main(){}
You can't assign a delegate at compile time now.
But you can do this in static constructor like this:
int delegate(int) dg;
static this()
{
dg = delegate int(int){ return 666; };
}
