Can you try again, I updated the installer and tried to revert

Converting Java code to D
Here is a fragment of Java code from an SWT program...
public enum LineStyle {
NONE(None),
SOLID(Solid),
DASH(Dash),
DOT(Dot),
DASHDOT(Dash Dot),
DASHDOTDOT(Dash Dot Dot);
public final String label;
private LineStyle(String label) {
this.label = label;
}
}
What would be the best ('canonical') way of translating it to D?

The constructor doesn't look very useful.
Perhaps a named enum is safer.

True, the constructor doesn't really add anything here.
To be honest, the combination of enumeration and runtime
variables in the Java code seems like a rubbish design, but
perhaps there's a good reason for it that I'm not aware of.
Maybe they extended enum to get over the lack of structs.
Looking at the spec for java enums it appears that you can return
an enumeration or the associated string using the original code.

sorry, but no. btw, if MyDataArray is struct, you should do
this:
foreach (ref m; mda) m.data.length = y;
or even this:
foreach (ref m; mda = new MyDataArray[](x)) m.data.length = x;
the thing is that without 'ref' you operates on the local copy,

Hi.
I've created a graphic button as per this example on the dgui
website:
import dgui.all;
class MyForm: Form
{
this()
{
text = An Exception was thrown...;
size = Size(130, 100);
// Or use `Bitmap.fromFile`:
auto img = new Bitmap(90, 15, SystemColors.yellow);
auto pen = SystemPens.blackPen;
with(new Button())
{
bounds = Rect(10, 10, 100, 25);
parent = this;
paint.attach((s, e)
{
e.canvas.drawImage(img, 5, 5);
e.canvas.drawLine(pen, 5, 10, 95, 10);
e.canvas.drawLine(pen, 10, 5, 10, 20);
});
}
}
}
int main()
{
return Application.run(new MyForm());
}

DMD Compiler - lexer
Hi, Looking at the DMD Source Guide it says The lexer transforms the file into an array of tokens. Why is this step taken instead of, say, just calling a function that returns the next token (or however many required for the look-ahead)? Regards, -=mike=-

Re: DlangUI
Vadim Lopatin coolreader@gmail.com wrote in message

Hello!
I would like to announce my project, DlangUI library - cross-platform GUI
for D.
https://github.com/buggins/dlangui
License: Boost License 1.0
Native library written in D (not a wrapper to other GUI library) - easy to
extend.
As a backend, uses SDL2 on any platform, Win32 API on Windows, XCB on
Linux. Other backends can be added easy.
Tested on Windows and Linux.
Supports hardware acceleration - drawing using OpenGL when built with
version=USE_OPENGL.
Unicode support.
Internationalization support.
Uses Win32 API fonts on Windows, and FreeType on other platforms.
Same look and feel can be achieved on all platforms.
Flexible look and feel - themes and styles.
API is a bit similar to Android UI.
Flexible layout, support of different screen DPI, scaling.
Uses two phase layout like in Android.
Supports drawable resources in .png and .jpeg, nine-patch pngs and state
drawables like in Android.
Single threaded. Use other threads for performing slow tasks.
Mouse oriented.
Actually, it's a port (with major redesign) of my library used for
cross-platform version of my application CoolReader from C++.
State of project: alpha. But, already can be used for simple 2D games and
simple GUI apps.
I'm keeping in mind a goal to write D language IDE based on dlangui. :)
Adding support of 3D graphics is planned.
Currently implemented widgets:
TextWidget - simple static text (TODO: implement multiline formatting)
ImageWidget - static image
Button - simple button with text label
ImageButton - image only button
TextImageButton - button with icon and label
CheckBox - check button with label
RadioButton - radio button with label
EditLine - single line edit
EditBox - multiline editor
VSpacer - vertical spacer - just an empty widget with layoutHeight ==
FILL_PARENT, to fill vertical space in layouts
HSpacer - horizontal spacer - just an empty widget with layoutWidth ==
FILL_PARENT, to fill horizontal space in layouts
ScrollBar - scroll bar
TabControl - tabs widget, allows to select one of tabs
TabHost - container for pages controlled by TabControl
TabWidget - combination of TabControl and TabHost
Layouts - Similar to layouts in Android
LinearLayout - layout children horizontally or vertically depending on
orientation
VerticalLayout - just a LinearLayout with vertical orientation
HorizontalLayout - just a LinearLayout with vertical orientation
FrameLayout - all children occupy the same place; usually onle one of them
is visible
TableLayout - children are aligned into rows and columns of table
List Views - similar to lists in Android UI API.
ListWidget - layout dynamic items horizontally or vertically (one in
row/column) with automatic scrollbar; can reuse widgets for similar items
ListAdapter - interface to provide data and widgets for ListWidget
WidgetListAdapter - simple implementation of ListAdapter interface - just
a list of widgets (one per list item) to show
Sample project, example1 contains demo code for most of dlangui API.
Try it using DUB:
git clone https://github.com/buggins/dlangui.git
cd dlangui
dub run dlangui:example1
Fonts note: on Linux, several .TTFs are loaded from hardcoded paths
(suitable for Ubuntu).
TODO: add fontconfig support to access all available system fonts.
Helloworld:
// main.d
import dlangui.all;
mixin DLANGUI_ENTRY_POINT;
/// entry point for dlangui based application
extern (C) int UIAppMain(string[] args) {
// resource directory search paths
string[] resourceDirs = [
appendPath(exePath, ../res/), // for Visual D and DUB builds
appendPath(exePath, ../../res/) // for Mono-D builds
];
// setup resource directories - will use only existing directories
Platform.instance.resourceDirs = resourceDirs;
// select translation file - for english language
Platform.instance.uiLanguage = en;
// load theme from file theme_default.xml
Platform.instance.uiTheme = theme_default;
// create window
Window window = Platform.instance.createWindow(My Window, null);
// create some widget to show in window
window.mainWidget = (new Button()).text(Hello
worldd).textColor(0xFF); // red text
// show window
window.show();
// run message loop
return Platform.instance.enterMessageLoop();
}
DDOC generated documentation can be found there:
https://github.com/buggins/dlangui/tree/master/docs
For more info see readme and example1 code.
I would be glad to see any feedback.
Can this project be useful for someone? What features/widgets are must
have for you?
Best regards,

Do you have any clues as to what the problem could be? I didn't compile this, so take it with a grain of salt. Access violation reading 0x is a null pointer dereference. Looking at the source: _drawbuf = loadImage(_filename); if (_filename.endsWith(.9.png)) _drawbuf.detectNinePatch(); I'm making a wild guess that loadImage returns a null if it can't find the file. Dereferencing thus throws. You probably lack the image or it's in the wrong place. Hi Casper, I checked the sub-directory the loading refers to and all the pngs seems to be there. Regards, -=mike=-

On Windows with scripting language, this is often done through COM automation: the IDispatch interface. With regular C functions, you really just have to know the prototypes ahead of time... it won't be fully dynamic, you load the library at run time but know how to use it at compile time. That's the way I do it but I was wondering. Is it better to load all the functions from the DLL at the start of the program or load them when required and keep having to check if they're loaded before each use? -Mike-

There was this article recently: http://www.onthemedia.org/story/yesterday-internet-solved-20-year-old-mystery/ about how english is so redundant one can write sentences using just the first letter of each word, and it is actually understandable. These examples are more about context than redundancy in the grammar. This is very interesting, because the burden is more and more on the listener and less on the speaker. The speaker can omit things relying on the listener's common sense or knowledge of the world (or you know what I mean skills). In the beginning, languages were quite complicated (8 or more cases, inflections), but over the centuries things have been simplified, probably due to the fact that humans are experienced enough and can now trust the interpreter in the listener's head. A good example are headlines. A classic is Driver refused license. Now, everybody will assume that it was not the driver who refused the license (default assumption or the _unmarked case_). If it were in fact the driver who refused the license, the headline would have been different, some sort of linguistic flag would have been raised. This goes into the realms of pragmatics, a very interesting discipline. Some of the concepts found in natural languages can also be found in programming languages. I find it extremely interesting how the human mind (not just language) is reflected in programming languages. Headlines are a good source. My favourites are from WW2... MacArthur flies back to front.

It's so weird when I feel myself do it, but it's awfully hard to control (I don't have mates to play music with... I play a lot with a delay/looper). One of the worst examples of this I've heard of was pipe organs in a very large church. The organist console sits at the opposite end of the church from the pipes, perhaps 100 feet away from some pipes, leading to extremely large delays. I read one account where low notes had a 300ms delay from pressing the pedal. Jerry Yeh - I had a friend who restored and played theatre organs.

Re: Overflow-safe use of unsigned integral types
On Sunday, 10 November 2013 at 12:05:45 UTC, Joseph Rushton
Wakeling wrote:
One of the challenges when working with unsigned types is that
automatic wraparound and implicit conversion can combine to
unpleasant effect.
Consider e.g.:
void foo(ulong n)
{
writeln(n);
}
void main()
{
foo(-3);
}
... which will output: 18446744073709551613 (or, ulong.max + 1
- 3).
Is there a recommended way to handle this kind of potential
wraparound where it is absolutely unacceptable? I've
considered the following trick:
void bar(T : ulong)(T n)
{
static if (isSigned!T)
{
enforce(n = 0);// or assert, depending on your
priorities
}
writeln(n);
}
... but it would be nice if there was some kind of syntax sugar
in place that would avoid such a verbose solution.
I know that there have been requests for runtime overflow
detection that is on by default (bearophile?), but it could be
good to have some simple way to indicate really, no overflow
even where by default it's not provided.
(Motivation: suppose that you have some kind of function that
takes a size_t and uses that to determine an allocation. If a
negative number gets passed by accident, the function will thus
try to allocate 2^64 - n elements, and your computer will have
a very happy time...:-)
When writing software for embedded micros you can always check an
overflow flag - is the no such mechanism on PC software?

And then it crashes.
Bye,

Strangely, if you replace the break instruction with continue (I know
it's pointless code), it also crashes...

GtkD - Changing the default windows font
Running on Windows 7, the default font is very thin and indistinct on my machine - is there a system setting to change the default font? regards, Mike.
Re: 1 matches bool, 2 matches long
gdc: bool x = false; x++; main.d:50: Error: operation not allowed on bool 'x' why not? is just an integer after all. another special case? If you are going to create a boolean then use it as a boolean - it's not an integer any more. Don't mix and match - there's nothing worse than trying to follow some code that uses a variable in one way then, out of lazyness, uses it in a different way. this works: int x = false; x++;

Consider these nested switches:
---
enum Foo {a, b}
enum Bar {bar}
auto foo = Foo.a;
auto bar = Bar.bar;
final switch(foo)
{
case Foo.a:
final switch(bar)
{
case Bar.bar:
XX
break;
}
break;
case Foo.b:
break;
}
---
Without adding extra code anywhere else, is there anything I can stick
in for XX to get execution to jump to case Foo.b:?
Doing goto case Foo.b; doesn't work. It just gives a compile error
that a Foo can't be implicitly converted to Bar.
This ability isn't critical, of course, but it would help clean up some
code I have.
Re: Exceptional coding style
Maybe I should invent a programming language in which color has semantic value. And fonts. :-P Sort of :-) http://www.colorforth.com/primer.htm -=mike=-
