Oh hey :-) I applied your patches for ddbc and hibernated a to my copy while back, because they weren't merged and fix real issues. There are also other patches floating around, for example people will really want https://github.com/KrzaQ/hibernated/commit/efa38c50effdd77e973b174feea89016b8d1fa1f applied when using hibernated. If there is enough interest, we can maybe provide at least some basic level of maintenance for these projects together, maybe under the dlang-community umbrella or similar. Per adoption guidelines[1], I think the projects are popular enough, but Hibernated is of course not the only D ORM (although a pretty complete one), and the continued maintenance is also not sure, even when PRs finally get reviewed and accepted faster (but that really depends on the library users).

Re: Access Violation when passing the result of a C function directly to a D function?

I'm compiling on Windows 7 x64, DMD32 D Compiler v2.075.1 and

Every Fmod function returns an int telling me if the function

helper function that will print something for me if it
encounters an error:
static void ErrorFMOD(int result, string msg = ""){
if(result != FMOD_OK)
writeln("[ FMOD ] ", msg, FMOD_ErrorString(result));
}
This function has been causing Access Violation Errors when I
call it. It doesn't happen every time and it doesn't always
happen in the same place. The errors occur _even when I comment
out everything inside the function_. I've been calling it like
so:
ErrorFMOD(FMOD_System_Create(), "Error Creating System:
");
Making the calls without my helper function doesn't cause an
Access Violation.
Calling it like this is the only thing that seems to fix it:
auto result = FMOD_System_Create();
ErrorFMOD(result, "Error Creating System: ");
Is this a known issue, or am I required to save the result of a
C function to variable before passing it into another function
or?
Probably you have to use const char * msg when interfacing with
C. string is a struct - size_t length and const char * value

Why struct destructor need Druntime? Compiler must simply past call of destructor before exit from scope or return statement. Where is Druntime here (dynamic allocations, pointers to scopes and other)? I think struct destructor must work in betterC code. Otherwise it will be one step to be likeC, not betterC. +1 I don't see the reason. If struct destructors were working correctly in betterC mode, it would be possible to use RAII. Missing RAII is a main reason of WTF messages when people see list of betterC limitations.

Если при открытии диалога создать файл будет выбран шаблон модуль и фокус на редакторе имени, а по Enter - срабатывать кнопка создания файла - все будет удобно. Создание папок само по себе достаточно бесполезно. Папки без файлов не показываются в Workspace explorer, а новая папка с файлом создается в диалоге выбора папки для файла. В Workspace Explorer есть еще один если не баг, то не очень удобный момент: при закрытии вкладки с кодом или при создании нового модуля, то есть по сути при "рефреше" дерева слетает текущее позиционирование курсора и состояние закрытых открытых узлов дерева. То есть перед "рефрешем" надо сохранить состояние курсора и состояние узлов дерева(раскрыт/закрыт), а после обновления восстановить (по-возможности) как было, с учетом того, что какие-то файлы/папки могут быть удалены.

I'm using DCD as a library in DlangIDE. All DCD calls are made from separate thread. DCD works ok until some thread is created (e.g. to invoke DUB for building). After this operation DCD stops working correctly and can locate symbols only from current source file. Root cause: If some another thread is created after DCD thread instantiated ModuleCache, DCD is not able to process goToDefinition for symbol and other functions if they are related to other modules than current source file. Probably, it's related to ModuleCache and/or allocators. Steps to reproduce: After creation of ModuleCache, start some thread and wait until it's finished. Does someone know some workaround?

Or perhaps there is an alternative that fits the bill of being production ready now, and either gives the same UI across all platforms or provides a platform UI with no change of source code, just a recompilation. There is DlangUI library. Gives same UI across all platforms, no source code change required, just recompilation. Widget set is not as full as in Qt or wx, but it's easy to extend, because DlangUI is not a binding, and written completely in D.

I wouldn't mind creating themes and adding them to DlangIDE as a humble contribution. Don't forget that contents of all those files in resources.list is also "hardwired" into the executable, so there's not much difference between mentioning something in such list file and in the source code. Of course, dynamic loading would be a nice thing to do, in addition to what there is now. Sure, but changing `resources.list` is trivial and can be added to the docs like so "Add the path to your theme file to `resources.list` and restart DlangIDE." It has to be hardwired somewhere, but it shouldn't be the themes. Other editors/IDE's allow you to load your own themes. This is important, because apart from aesthetics, some people might find certain themes easier on the eye than others, e.g. color blind people or people with some sort of visual impairment. Hello, External themes support is planned. It is not a hard task. Btw, try to copy your resource files (res directory) to the same place dlangui executable (e.g. dlangide) is located. Resources from this directory must be accessible from application. The only problem should be list of themes in UI settings. AFAIR, resources from directory should have higher priority than embedded ones. So for testing, you can rename theme to standard name. Best regards, Vadim

Did you see example1 from examples folder in dlangui? It has
two languages and allows switching at runtime via menu.
But I don't know how to change the language for ui components
such as buttons and text. And the most important thing is
removing "UNTRANSLATED: " from items in my list.
Are you really see it on example1? It looks like you selected
Russian language in "View"/"Interface Language" menu. Select
English (in russian translation, it's first item of third main
menu item -- "Вид"/"Язык интерфейса").
UNTRANSLATED: prefix is being added to all string resources not
found in translation files.
For widgets, usually both plain unicode dstring values and string
resource ids can be used.
E.g.
`label.text = "exit"c;` assigns string resource id
(views/res/i18n/your_language_code.ini should contain line
"exit=SOME_TRANSLATION_HERE", otherwise "UNTRANSLATED: exit" will
be shown. Strings specified by resource ids will be automatically
translated when language is changed.
`label.text = "exit"d; assigns plain unicode string value. Such
strings remain unchanged when application language is changed.
In DML, when you assign string property as identifier (w/o
quotes), it's considered as resource id. When "string in quotes"
is assigned, it's plain string.
TextWidget { text: RESOURCE_ID } // translation must exist in
res/i18n/*.ini files
TextWidget { text: "plain text" } // just plain text value

Shouldn't there be like a common (interface/abstract class)

these things are done. And perhaps there are performance
reasons that many of these are baked in.
perhaps it should be like:
standard color implementation.
font interface that converts glyphs into drawing strokes.
and a standard set of drawing instructions with transforms.
//probably a grotesque simplification
interface font_do{
glyphstrokes getstrokes(string characterstoget);
}
interface draw_do{
drawpixel(double x,double y);
drawline(double x,double y);
drawglyph(glypstrokes g);
getpostdrawnsize(glypstroks g)
... other things
}
I can consider splitting of DlangUI library into platform and
widgets.
Platform will provide window creation, initialization of OpenGL
context when necessary, keyboard and mouse events, user events.
As well, it has font support - FreeType and on Windows it can use
native Windows fonts.
Currently supported platforms:
Windows: Win32 API or SDL
Linux, OSX: SDL or X11
I'm planning to make Cocoa (native OSX) and Wayland (for Linux)
support later.

However this requires that I write the image out to disk, and then load it again to display it. Is there any way I can update or create the image in memory without going to disk? Thanks, Eric Hello, Sorry for delayed answer. Is your question still actual? You can use something like // create RGBA drawing buffer ColorDrawBuffer buf = new ColorDrawBuffer(width, height); // copy pixels into buf from your custom image // . // put into DrawBufRef DrawBufRef imageDrawBuf = buf; // create image drawable DrawableRef myCustomImageDrawable = new ImageDrawable(imageDrawBuf); // set drawable of ImageWidget imageWidget.drawable = myCustomImageDrawable; There was code in dlangui.graphics.image which could copy FreeImage images to ColorDrawBuf, but in recent version it's removed. You can check github revision history to get proper code. BTW, why do you need FreeImage to create image? Isn't it just possible inside dlangui?

I have a variable, x, which I want to update when the content

working now by implementing a custom subclass of EditLine as
below:
class XEditLine : EditLine

this(string ID, dstring initialContent = null)
{
super(ID, initialContent);
}
override bool onKeyEvent(KeyEvent e)
{
super.onKeyEvent(e);
x = to!double(this.text);
return true;

This works but it seems like there should be a cleaner way to
do this, any suggestions? Thanks.
You can either override onContentChange or use
onContentChangeListener
override void onContentChange(EditableContent content,
EditOperation operation, ref TextRange rangeBefore, ref TextRange
rangeAfter, Object source) {
super.onContentChange(content, operation, rangeBefore,
rangeAfter, source);
// do something
x = to!double(this.text);
}
or
EditLine line = new EditLine();
line.onContentChangeListener = delegate(EditableContent) {
// do something
x = to!double(line.text);
}
of a DlangUI EditLine is modified. I tried making this work
with the onContentChange method listed in the API
documentation, but dmd told me it's not there. I've got this
If you don't see onContentChange method, probably you have older
version of DlangUI. Try dub upgrade --force-remove

Best regards, Vadim I once remember pulling out my hair trying todo the same in order to get it to work with a monodevelop win32 debugger addon. It resulted in a writing new clr wrapper with a different exposed interface https://github.com/aBothe/MagoWrapper e.g. of how the debugee was was launched here: https://github.com/aBothe/MagoWrapper/blob/master/DebugEngine/MagoWrapper/NativeDebugger.cpp Thank you a lot! BTW, it's not clear what license in used for MagoWrapper. In readme, it's said that it's under GPL2, but everywhere in source code I see Apache license.

DDOX question
Hello! I'm trying to generate documentation for a library. I like result of DDOX generation - nice navigation by modules and classes. But I cannot figure out how to generate custom pages (e.g. from .dd .d Ddoc), and how to add links to custom pages to all generated pages, e.g. like on Vibe.d documentation site. Could someone point on example or docs wich can help me? Best regards, Vadim
Customization of DUB build=DDOX output
Hello, I'm trying to use DDOX to generate documentation pages for my library (dlangui). dub --build=ddox produces nice output with navigation by modules, but I cannot find out how to embed some custom navigation pane on all pages. E.g. put links to some additional pages like downloads, screenshots, github... Is it possible to do it using dub+ddox build? Best regards, Vadim
