[Issue 14425] New: Indirect template instantiation within is expression causes missing linker symbols
https://issues.dlang.org/show_bug.cgi?id=14425
Issue ID: 14425
Summary: Indirect template instantiation within is expression
causes missing linker symbols
Product: D
Version: D2
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: P1
Component: DMD
Assignee: nob...@puremagic.com
Reporter: slud...@outerproduct.org
The following causes the linker to complain about missing
Foo!string.__xopEquals and .__xtoHash:
---
struct Foo(I) { I i; }
struct Bar(I) { I i; }
static assert(is(Foo!(Bar!string)));
---
Workaround is to explicitly instantiate the template:
alias Workaround = Foo!(Bar!string);

Implementing Iterator to support foreach
I am planning to implement Iterator class. But looking at
foreach statement, it takes a range only.
So is there any way other than returning an array from a function
that is to be passed foreach statement? So I could write like
that:
Iterator iter = new MyList();
foreach(item; iter){
}
Otherwise I will need to write like that:
foreach(item; iter.getArrayOfAvailableItems()){
}

DDMD is now in the master branch
Several hours ago, Walter merged my DDMD branch into master. This means that an additional 'ddmd' target is available in the makefiles, and the autotester will check that it builds. The make target converts the C++ frontend source to D, and then compiles with the host dmd. The converter is included in the DMD repo for now. If you are a DMD developer, pull requests may need to be updated to modify the converter's configuration file, or to replace problematic code that cannot be converted. Details can be found here: http://wiki.dlang.org/Updating_Pull_Requests_for_DDMD For everyone else, please test the generated ddmd binary with your projects and report any correctness or performance problems you encounter. I'm also interested in feedback on the quality of the generated D source. When we are satisfied with the quality of the D version, we will switch over all development to it and delete the C++ source. If we're lucky this will happen before the 2.068 release. Thanks to everybody who has helped with DDMD over the last two years.

Yes, I don't like writeln being used with UFCS, it's an
abuse.
My point is that every language has WATs :-)
Why is it 'an abuse'? Do you special case any other functions
or is names.parallel unacceptable as well? Are longer chains
ending in writeln acceptable or do you insist in putting the
whole chain inside a parens writeln?
name.reverse.writeln
or
writeln(name.reverse)
or surely that would break your dislike of single UFCS
arguments so you should stick to:
writeln(reverse(name))
Which is proper yoda speak.
At the very least, put () after the writelne:
name.reverse.writeln();
Using the property getter style for a function used solely for
it's side-effects kind of conceals what you are trying to do
here...
At any rate, since UFCS allows you to choose the order your code
will be read in, you should try give as much information as soon
as possible:
`writeln(name.reverse);` - the first word is `writeln`, so I know
it's a statement that's going to write something to stdout.
`name.reverse.writeln();` - the first word is `name`, so I know
it has something to do with the name.
Decide which one to use based on the first impression you want
people to get from that statement.

Question number 2: Is it possible to change the VectorFunc to

I did something along these lines (modified to match your
example) and it worked fine for me:
alias VectorFunc = void function();
@attribute(weak) @attribute(alias, defaultHandler)
extern void Reset_Handler();
@attribute(weak) @attribute(alias, defaultHandler)
extern void NMI_Handler()
@attribute(weak) @attribute(alias, defaultHandler)
extern void HardFault_Handler();
@attribute(section,.isr_vector.ro)
immutable ISR[3] g_pfnVectors =
[
Reset_Handler
, NMI_Handler
, HardFault_Handler
];
I did this before weak, alias, and section attributes were
added, however. To see my original code, look at the slide in
the presentation here: https://youtu.be/o5m0m_ZG9e8?t=2332. My
original code had everything decorated with extern(C) as well so
I could refer to the symbol directly in my linker scripts. That
may not be needed for you, so I left it out.
Question number 3: How can I call an external function and keep
the binary file size down ?
Are you compiling with -ffunction-sections -fdata-sections and
linking with --gc-sections? You may need to in order to get rid
of some things.
What do you using for your D runtime? Perhaps some code in your
runtime is implicitly linking to some code you're not directly
calling.
I also add the following to my linker scripts to get rid of stuff
I don't find necessary:
/DISCARD/ :
{
*(.ARM.extab*)
*(.ARM.exidx*)
}
/DISCARD/ :
{
*(.ARM.attributes*)
*(.comment)
}
You can see the latest incarnation of my linker script here:
https://github.com/JinShil/stm32f42_discovery_demo/blob/master/linker/linker.ld
Question number 4: How can I reduce the function declaration of
the Reset_Handler and NMI_Handler shown above ?
Try something along these lines.
enum weak = gcc.attribute.attribute(weak);
enum isrDefault = gcc.attribute.attribute(alias,
defaultHandler);
extern @weak @isrDefault void NMI_Handler();
extern @weak @isrDefault void HardFault_Handler();
I use this idiom briefly in my code here:
https://github.com/JinShil/stm32f42_discovery_demo/blob/master/source/start.d
The enum thing kinda bugs me about D, but you'll see it used
everywhere, especially phobos. It's called a manifest constant,
and you can find a short blurb about it at the bottom of this
page: http://dlang.org/enum.html

function shadowed
i got two modules
opengvg.d and vg.d
vg.d contains calls to external c functions
openvg.d should wrap and simplify some of those calls
in openvg.d i make public import of submodule vg.d
such that if openvg.d is imported the functions in vg.d can be
called, this works as intended. but as soon as i overload a
function from vg.d in openvg.d i can only call the function in
openvg.d
example:
vg.d:
module vg;
extern (C) void vgSetParameterfv(VGHandle object, VGint
paramType, VGint count, VGfloat *values);
openvg.d
module openvg;
public import vg;
void vgSetParameterfv(VGHandle object, VGint paramType,
const(VGfloat[]) values)
{
vg.vgSetParameterfv(object, paramType, cast(int)values.length,
cast(VGfloat*)values);
}
test.d
import openvg;
vgSetParameterfv(object, paramType, length, values); // call to
fun in vg.d
how can i call both functions? i'd like to avoid using the module

Generating all combinations of length X in an array
Hi folks,
While trying to generate all combinations of length X in an array,
I came across the question on stackoverflow. [1]
Theres a couple good answers there, but one that caught my eye
shows a C# code snippet that is quite nice and short:
public static IEnumerableIEnumerableT CombinationsT(this
IEnumerableT elements, int k)
{
return k == 0 ? new[] { new T[0] } :
elements.SelectMany((e, i) =
elements.Skip(i + 1).Combinations(k - 1).Select(c = (new[]
{e}).Concat(c)));
}
I spent a couple hours trying to translate this to D, but couldnt
get my head around the SelectMany statement.
I think it's analogous to std.algorithm.map, but it seems quite
difficult to mimic the behaviour using map.
Anyone with more knowledge and/or skills like to have a crack?
Thanks!

Would it work in D to say compile a shared library and generate a number of .di files required to use it? Similar to druntime that provides only a hand full of its modules as .di or where necessary as .d files. I'm looking for a perspective out of the compile the world model in Dlang, since as far as I understand it, the D front-end will always parse all imported modules recursively. Even in single-file compilation mode, when only app.d changed it would parse the whole thing down to the last corner of all used D libraries like GtkD or vibe.d. With the minimum amount of required .di files for libraries, further private imports inside their modules are hidden away from the compiler, thereby short-circuiting the import the world recursion. -- Marco

Is it any faster to read array slices than just elements of an array?
While I technically finished the 0.2 version of my graphics engine which has a reasonable speed at low internal resolutions and with only a couple of sprites, but it still gets bottlenecked a lot. First I'll throw out the top-down determination algorhythm as it requires constant memory paging (alrought it made much more sense when the engine was full OO and even slower). Instead I'll use a overwriting (bottom-up) method. It still needs constant updates and I have to remove the per sprite transparency key and use a per layer key, however it requires much less paging, and still have the ability of unbound layer numbers and sprite count with unbound sizes. I also came up with the idea of reading slices out from the graphical elements to potentially speed up the process a bit, especially as the custom bitmaps it uses are 16bit for palette operations, so per pixel read operations would waste a portion of memory bus. So should I write a method for the bitmap class which gets a line from it? (an array slice as it contains the data in a single 1D array to avoid jagged arrays on a future expansion for a scaler) And can I write an array slice at a position of an array? (to reduce writeback calls)

It tells a *File* to do something. writeln is an OutputRange. It takes its input from the pipeline and places it in a container (the screen). But it is actually a method of stdout file, which was what Adam has pointed out. Hiding it behind free function and abusing that fact for UFCS is just mixing semantics and, well, abuse.

It isn't even remotely close to one - an OutputRange is a type, writeln is a function. isOutputRange doesn't even return false for it, it outright fails to compile! File isn't an output range either btw. An output range is defined by the presence of a put method, which File doesn't have. b.d(4): Error: static assert (isOutputRange!(File, char)) is false Even putting aside the formal definition of output range, output is NOT part of the pipeline! Pipelines can be composed and they keep pumping data through them. writeln does not transform its input nor does it forward it to the next item in the pipe. It just eats it. That's totally different than everything else in the sequence. And that's not even bringing in writeln's sister function, writefln, whose first argument isn't what is to be printed at all! (it can show something to print but passing arbitrary strings to writef as the first argument is a major program bug, you should never do it)

Thanks, Bogdan Nice! I'll give it a try when I get some time to set up a little private FileDAV server.

I want to experiment with that and I know no other production ready language which has this level of support, except the original gangsta Eiffel but the only supported Eiffel compiler is proprietary and and expensive. Doesn't a OSS version exist, in paralelle auf the commerzial one ?
An input range iteration question
If Iterator is a struct then Iterator.input won't be adjusted
properly when the foreach loop ends.
Iterator.input still holds abcde value.
If i mark Iterator as class then Iterator.input will be an empty
string after the foreach loop.
Could anyone explain me the difference please?
Thank you.
struct Iterator {
string input;
this(string input) {
this.input = input;
}
bool empty() { return input.empty; }
dchar front() { return input.front; }
void popFront() {
if (empty) {
return;
}
input.popFront();
writeln((iterator.popFront), input);
}
}
void main(string[] args) {
Iterator iterator = Iterator(abcde);
foreach (dchar c; iterator) {
writefln(%s, c);
}
writefln((the end): %s, iterator.input);
}
