I have a question about creating native GUI applications for Windows 7 or/and Windows 10. I know that exist DWT, DlangUI and other... But I'm interesting in native GUI. If it will be C++ then I would use WinAPI from SDK. And what about D? What should I do? Make some kind of wrapper above C WinApi? I also know that on GitHub exists such wrapper (https://github.com/AndrejMitrovic/DWinProgramming) but it is old - last commit was 4 years ago. Could you help me? You can use libuid which can be found here https://code.dlang.org/packages/libuid. It wrapped the native os gui for d, and it's cross-platform. Any chance of having a version that allows static linking? Zz
ndslice help.
Hi,
Just playing with ndslice and I couldn't figure how to get the
following transformations.
given.
auto slicea = sliced(iota(6), 2, 3, 1);
foreach (item; slicea)
{
writeln(item);
}
which gives.
[[0][1][2]]
[[3][4][5]]
what transformation should i do to get the following from slicea.
[[0][2][4]]
[[1][3][5]]
[[4][2][0]]
[[5][3][1]]

Hi,
void main()
{
auto slicea = sliced(iota(6), 2, 3, 1);
auto sliceb = slicea.reshape(3, 2, 1).transposed!1;
auto slicec = sliceb.reversed!1;
writefln("%(%(%(%s%)\n%)\n\n%)", [slicea, sliceb, slicec]);
}
Output:
[0][1][2]
[3][4][5]
[0][2][4]
[1][3][5]
[4][2][0]
[5][3][1]

Thanks
ndslice help
Hi, I'm trying to generate the following sequences with ndslice. 0 0 0 1 1 1 1 1 1 0 0 0 0 1 2 0 1 2 2 1 0 2 1 0 It's okay with loops but was checking to see if it's possible with ndslice. Zz

Zz Here's my solution: http://dpaste.dzfl.pl/29676608fd88 The best part about ndslice is that you can use the ordinary slice operations with it like: http://dlang.org/spec/arrays.html#array-copying, http://dlang.org/spec/arrays.html#array-setting, http://dlang.org/spec/arrays.html#array-operations, etc. and also leverage the existing ranges, range transformations and algorithms from http://dlang.org/phobos/std_range and http://dlang.org/phobos/std_algorithm. In addition, I used nested array formatting with http://dlang.org/phobos/std_format. Thanks Zz
Guide - Migrating from std.experimental.ndslice to mir-algorithm
Hi, Just tried migrating from std.experimental.ndslice to mir-algorithm. Is there a guide on how migrate old code? I used the following imports before and using then with ndslice. import std.experimental.ndslice; import std.algorithm : each, max, sort; import std.range : iota, repeat; simplified example of how it was used. auto a = cr.iota.sliced(r, c); auto b = a.reshape(c, r).transposed!1; auto c = a.reversed!1; auto d = a.reshape(c, r).transposed!1.reversed!1; auto f = new int[cr].sliced(r, c); auto h = f.transposed(1); how can I do the following in mir-algorithm. Note: I will be going through the documentation. Zz

Zz Hello Zz, std.experimental.ndslice -> mir.ndslice std.range : iota, repeat -> mir.ndslice.topology: iota, repeat; std.algorithm : each; -> mir.ndslice.algorithm: each; std.algorithm : max; -> mir.utility: max; std.algorithm : sort; -> mir.ndslice.sorting: sort; Note, that Mir functions has different semantics compared with Phobos! For example, each iterates deep elements, so should be combined with `pack` to iterates rows instead of elements. Ndslices work with Phobos functions but it is suggested to use Mir analogs if any. // Mir's iota! It is already 2D ndslice :-) auto a = [r, c].iota; auto b = a // returns flattened iota, a has Contiguous kind, // so the result type would be equal to `iota(r*c)` .flattened // convert 1D iota ndslice to 2D iota ndslice .sliced(c, r) // It is required to use transposed // Convert ndslice kind from Contiguous to Universal. .universal // Transpose the Universal ndslice .transposed; auto c = a.universal.reversed!1; auto d = a.flattened.sliced(c, r).universal.transposed!1.reversed!1; // see also `rotated` auto f = slice!int(c, r); // new int[cr].sliced(r, c); works too. auto h = f.universal.transposed(1); --- Mir ndslices have three kinds: http://docs.algorithm.dlang.io/latest/mir_ndslice_slice.html#.SliceKind If you have any questions feel free to ask at the Gitter: https://gitter.im/libmir/public Best, Ilya Best, Ilya Thanks

jsoniopipe - exaples?
Hi,
Here are some samples from the std.json documentation.
Any idea on how to do something similar using jsoniopipe?
Directly copied from https://dlang.org/phobos/std_json.html
import std.conv : to;
// parse a file or string of json into a usable structure
string s = `{ "language": "D", "rating": 3.5, "code": "42" }`;
JSONValue j = parseJSON(s);
// j and j["language"] return JSONValue,
// j["language"].str returns a string
writeln(j["language"].str); // "D"
writeln(j["rating"].floating); // 3.5
// check a type
long x;
if (const(JSONValue)* code = "code" in j)
{
if (code.type() == JSONType.integer)
x = code.integer;
else
x = to!int(code.str);
}
// create a json struct
JSONValue jj = [ "language": "D" ];
// rating doesnt exist yet, so use .object to assign
jj.object["rating"] = JSONValue(3.5);
// create an array to assign to list
jj.object["list"] = JSONValue( ["a", "b", "c"] );
// list already exists, so .object optional
jj["list"].array ~= JSONValue("D");
string jjStr =
`{"language":"D","list":["a","b","c","D"],"rating":3.5}`;
writeln(jj.toString); // jjStr

Zz

How pretty-print a struct?
Hi, Is there an easy way to pretty-print a struct which also includes arrays? pretty_array does a very good job for arrays. ZZ
