Yah static foreach is slow for sure. Part of the problem is that 
it literally just runs a lambda at CTFE that creates a tuple. So 
that static foreach 0 .. 1 literally creates a tuple with 
1 elements. Might even create an array first that then gets 
converted to that tuple. So yah, not very efficient at all.

Rising a dead module : SimpleVFS, a fork of D:GameVFS

[Luis via Digitalmars-d-announce]

Well, I need a simple VFS for my pet/toy game engine. And the 
only dub package that give me this... D:GameVFS. And it was 
abandoned some time ago.
So, I clone it, fixed & updated to work with D frontend 2.090, 
added travis and appveyor CI autotesting, documentation living on 
on GH pages, added package.d ...
I try to contact with the original author, and before waited some 
days for a response, I decide to publish my fork with a new name. 
So, if someone need a simple VFS, you can take a look to :


https://zardoz89.github.io/SimpleVFS/index.html

The initial release, 0.2.1, it's source compatible with D:GameVFS 
.


My TODO list for future versions, are :

* Rename modules to simplevfs.XXX
* Modernize the tests to use Silly
* Improve the test battery with more cases
* Check why it's using std.c.stdlib, and avoid using it. 
std.c.stdlib : fseek isn't compatible with files bigger that 2 
GiB ( don't calls _fseeki64 )
* Work to make @nogc friendly, if I can... I need to check how 
works exceptions with @nogc code.

Well, duh. I put the cart before the horse on that one. SDL2.dll 
is going to be in the same subdirectory since all the others 
depend on it and will fail to load if it isn't there (they don't 
load it dynamically, of course).


Working with args[0] or, since this is a Windows-only thing, 
calling the Win32 API directly (GetModuleFileName, IIRC) will get 
you there.

BindBC Updates: new loader function, SDL_net, streamlined SDL_* version indentifiers

[Mike Parker via Digitalmars-d-announce]

I've recently implemented some improvements centered on 
bindbc-sdl.


== New Loader Function

I've added a function to bindbc-loader (on Windows only) to allow 
adding a single path to the default DLL search path. This is to 
solve the problem that some of the SDL satellite libraries would 
fail to load when placed in a directory outside of the search 
path, such as a ./libs subdirectory.


The problem is that SDL loads its dependencies dynamically. So 
when a bindbc user would load a lib with a custom path, e.g., 
`loadSDLImage("libs\\SDL2_image.dll")`, the system loader would 
find that DLL just fine, but then when it in turn attempted to 
load a dependency like libpng, the system loader would search the 
DLL search path and *not* the libs subdirectory, thereby causing 
a failure.


Now you can do this:

```
version(Windows) setCustomLoaderSearchPath("libs");

if(loadSDL() < sdlSupport) { /* handle error */ }
if(loadSDL_Image() < sdlImageSupport) { /* handle error */ }

// Give SDL_image a chance to load libpng and libjpeg (it loads 
them lazily

// when the corresponding flags are passed to IMG_Init.
auto flags = IMG_INIT_PNG | IMG_INIT_JPEG;
if(IMG_Init(flags) != flags) { /* handle error */ }

// Now reset the default loader search path
version(Windows) setCustomLoaderSearchPath(null);
```

It's up to the caller to ensure the path is valid. For example, 
if the executable is run from a different directory, then "libs" 
will not be relative to the current working directory. 
`SDL_GetBasePath` can help there:


https://wiki.libsdl.org/SDL_GetBasePath?highlight=%28%5CbCategoryFilesystem%5Cb%29%7C%28CategoryEnum%29%7C%28CategoryStruct%29

I'm unaware of any issues with other libraries BindBC binds to, 
but if they do arise, this will solve those, too.


== SDL_net

I didn't initially port SDL_net over because I didn't think 
anyone was using it. I was waiting for someone to request it. 
Someone did. It's a small API, so it took a matter of minutes to 
complete.


== Streamlined SDL_* version identifiers

Previously, the SDL satellite library bindings could be enabled 
with e.g., `BindSDL_Image`, `BindSDL_TTF`, etc. That would enable 
the lowest supported version of the library. To enable a more 
recent version, an additional identifier was required 
(`SDL_Image_205`, `SDL_TTF_2014`). That's just dumb. Now, only 
one identifier is required, e.g., `SDL_Image_205` will do the 
trick by itself now. `SDL_Image` is equivalent to the 
`SDL_Image_200`. The old approach is still supported, though, so 
current build configs should continue to work without change.


See the loader documentation for details on the new function:

https://github.com/BindBC/bindbc-loader

There's also a bit about it in the bindbc-sdl documentation, 
along with the details about the approach to version identifiers.


https://github.com/BindBC/bindbc-sdl/blob/master/README.md

I've got some bigger packages to port over from Derelict yet (the 
OpenCL binding, for example). I've also had a request to include 
support for SDL's thread/mutex API so folks using DasBetterC can 
have access to it. That's all in the pipeline. Going forward, I 
plan to devote a handful of hours one day a week to bindbc until 
I've implemented everything on my task list, so it will get done 
sooner rather than later.

It's always exciting to see D used in teaching! :) Alex Ortiz, my 
contact at Educative.io, has student discounts. He say:



Please have them reach out if they'd like to use this course as part of 
the curriculum.


Maybe those students can avail themselves of Educative-related 
resources. We're part of the GitHub Student Education
Pack , through which college students 
can avail themselves of a free 6-month subscription to our courses. We 
also sometimes have special scholarships in place on our side. Finally, 
we can offer university students specifically of your course a 
discounted rate or somesuch.


In any case, the professor can in the future email *supp...@educative.io 
*, explain that they're a
professor who wants to use your course(s) in their university 
curriculum, and ask what we have in place to help their

students.

This is great! Finally, a D course. It is a shorter than "Programming in

Educative.io decided to provide the book in two parts. They are still
