If user continues to type in a UFCS method, and that doesn't match any members, the autocomplete should start looking for functions that start with that text.

Re: Mixin statements
Also a feature that would make this perfect is macro template
arguments.
Something like
void templateFunction(macro a)()
{
int x = 5;
return mixin(a);
}
Essentially, the expression in the argument would be converted to
an expression macro.
Calling templateFunction!(x + x)() would return 10
Why would you want this over string mixins?
For one, it looks a lot cleaner.
Also as its not a string, it cant be changed and the parser need
not re-parse it when it gets mixed in, which could be faster than
normal string mixins.
Also it would allow for mixin macros to look something similar to
c++ macros only with the mixin keyword in front of it. Would keep
the whole thing clean looking.
Example assert doing c style return error codes.
mixin macro cassert(macro expression, alias errorcode)
{
if(!(mixin(expression))) return errorcode;
}
... some other piece of code that returns null on error ...
mixin cassert(x == 3, null);

[Issue 14682] [REG2.037] Incorrect interpretation of ~ []
https://issues.dlang.org/show_bug.cgi?id=14682
--- Comment #12 from Kenji Hara k.hara...@gmail.com ---
(In reply to Kenji Hara from comment #3)
At a concatenation expression, arr ~ elem is preferred than arr ~ arr2 when
elem is implicitly convertible to typeof(arr[i]). In the code, the rhs `[]`
is implicitly convertible to typeof(foo) == string.
Sorry I was mistaken. Normally D's array concatenation prefers two arrays
concat, rather than prepending/appending one element.
I noticed a comment in CatExp::semantic explains how the ambiguity should be
resolved to.
if (tb1next tb2next
(tb1next-implicitConvTo(tb2next) = MATCHconst ||
tb2next-implicitConvTo(tb1next) = MATCHconst
)
)
{
/* Here to avoid the case of:
*void*[] a = [cast(void*)1];
*void*[] b = [cast(void*)2];
*a ~ b;
* becoming:
*a ~ [cast(void*)b];
*/
}
And in CatAssignExp::semantic, array appending is already preferred than
element appending.
int[] a1;
int[][] a2;
int[][][] a3;
import std.stdio;
{ auto x = a1 ~ []; x.writeln(); } // prints []
{ auto x = a2 ~ []; x.writeln(); } // prints []
{ auto x = a3 ~ []; x.writeln(); } // prints []
Therefore I can say it's just an implementation bug in dmd.

Mixin statements
Can we get a way to mix in statements and expressions? Current
mixin templates only allow mixing in declarations. The only way
to actually mixin statements is through string mixins which are
not parsable by auto complete and such, and are really over kill
for a lot of common uses.
My first thought was to just allow statements in a mixin template
but that does not really make sense. Where would the statements
be placed for
mixin someMixInTemplateName!() A;
So I propose using the currently unused macro keyword for it(I
don't think it will ever be used for AST macros any ways...)
mixin macro macroTemplateName(ARGS...)
{
statements or declarations to be mixed in.
}
and could be use in the same way as mixin templates, just without
giving it a name. Example...
mixin macroTemplateName!();
Also an extension of this would be to allow expression macros. I
haven't really thought of a good syntax for defining these
though, but maybe something like...
mixin macro expressionMacroName() = (some expression to be mixed
in);
I am not totally sure on that though because I feel like you
would want to be able to do static if's and such, but you could
probably at that point call out to a more complex template to
handle things like that. The only purpose of the expression macro
would be to allow it to capture identifiers in the calling scope.
Could be used like string mixins. Example...
int a = 3 + 5 + mixin(expressionMacroName!());
Thoughts? Is this something that any one else has wanted?

A Vision on Improved DMD Template Instantiation Diagonostics
After having seen Andrei's Walter's talks on DConf 2015 it's time reveal a dream of mine. It resolves around of feature that I believe is one of the most important improvements that will benefit aggregation of more *new* users to the D Community. Namely a more clever DMD diagnostics when a template instantion fails to match any template definition in the current scope. For instance, if f(a,b,c,d) fails to match any of the overloads f(a,b,c) if (PRED_1(a,b,c) PRED_2(a,b,c)) f(a,b,c,d) if (PRED(a,b) PRED(b,c) PRED(c,d)) instead of saying Error: neither of these matched - f(a,b,c) if (PRED_1(a,b,c) PRED_2(a,b,c)) - f(a,b,c,d) if (PRED(a,b) PRED(b,c) PRED(c,d)) it should instead say Error: no template match to call of f(a,b,c,d) for neither - f(a,b,c) if (PRED_1(a,b,c) PRED_2(a,b,c)) - because template restriction `PRED_2(a,b,c)` evaluate to false - f(a,b,c,d) if (PRED(a,b) PRED(b,c) PRED(c,d)) - because template restriction `PRED(b,c)` evaluated to false Eventhough this might be a bit tricky to get right and may break lots of existing diagnostics (in DMD unittests), I'd say it's definitiely worth effort. Such a feature would attract lots of new users not used to D's advanced template restrictions. All users, newbies aswell as experts, would be benefit from this feature. I you DMD review guys are interested in getting this in and helping me out on source code directions I'd be very happy to start working on DMD PR for this. Destroy.

While most handsets are bought with pre-paid cards, iPhone requires a contract. Before Apple was reborn, buying a Mac meant having to travel to Porto or Lisbon and get one there, with leasing. Same thing to get them repaired. My university in Lisbon (UNL) was the first time I got to see LCs live, even then only used by administrative personal and one room for students with around 10 of them. Everywhere else on the campus there were DG/UX, Aix terminals and PCs available. Nowadays you can get them everywhere at a big surface, but for most families still means making use of 3 - 5 years leasing, given the average salaries and life cost. -- Paulo

I have no desire to join D with Fortran libraries :) D definitely needs BLAS API support for matrix multiplication. Best BLAS libraries are written in assembler like openBLAS. Otherwise D will have last position in corresponding math benchmarks. A complication for linear algebra (or other mathsy things in general) is the inability to detect and implement compound operations. We don't declare mathematical operators to be algebraic operations, which I think is a lost opportunity. If we defined the properties along with their properties (commutativity, transitivity, invertibility, etc), then the compiler could potentially do an algebraic simplification on expressions before performing codegen and optimisation. There are a lot of situations where the optimiser can't simplify expressions because it runs into an arbitrary function call, and I've never seen an optimiser that understands exp/log/roots, etc, to the point where it can reduce those expressions properly. To compete with maths benchmarks, we need some means to simplify expressions properly. Simplified expressions would [NOT] help because 1. On matrix (hight) level optimisation can be done very well by programer (algorithms with matrixes in terms of count of matrix multiplications are small). Perhaps you've never worked with incompetent programmers (in my experience, 50% of the professional workforce). Programmers, on average, don't know maths. They literally have no idea how to simplify an algebraic expression. I think there are about 3-4 (being generous!) people in my office (of 30-40) that could do it properly, and without spending heaps of time on it. 2. Low level optimisation requires specific CPU/Cache optimisation. Modern implementations are optimised for all cache levels. See work by KAZUSHIGE GOTO http://www.cs.utexas.edu/users/pingali/CS378/2008sp/papers/gotoPaper.pdf Low-level optimisation is a sliding scale, not a binary position. Reaching 'optimal' state definitely requires careful consideration of all the details you refer to, but there are a lot of improvements that can be gained from quickly written code without full low-level optimisation. A lot of basic low-level optimisations (like just using appropriate opcodes, or eliding redundant operations; ie, squares followed by sqrt) can't be applied without first simplifying expressions. OK, generally you are talking about something we can name MathD. I understand the reasons. However I am strictly against algebraic operations (or eliding redundant operations for floating points) for basic routines in system programming language. That's nice... I'm all for it :) Perhaps if there were some distinction between a base type and an algebraic type? I wonder if it would be possible to express an algebraic expression like a lazy range, and then capture the expression at the end and simplify it with some fancy template... I'd call that an abomination, but it might be possible. Hopefully nobody in their right mind would ever use that ;) Even float/double internal conversion to real in math expressions is a huge headache when math algorithms are implemented (see first two comments at https://github.com/D-Programming-Language/phobos/pull/2991 ). In system PL sqrt(x)^2 should compiles as is. Yeah... unless you -fast-math, in which case I want the compiler to do whatever it can. Incidentally, I don't think I've ever run into a case in practise where precision was lost by doing _less_ operations. Such optimisations can be implemented over the basic routines (pow, sqrt, gemv, gemm, etc). We can use approach similar to D compile time regexp. Not really. The main trouble is that many of these patterns only emerge when inlining is performed. It would be particularly awkward to express such expressions in some DSL that spanned across conventional API boundaries.

How to pass voldemort types to functions
Hi; I have tuples created by std.algorithm.group function. auto tupleB = stringB.group(); I need to write a a function which takes tubleB and do some cool stuff. If I don't use a function and write all code below .group() everytihng works but for reusing the code I want to call a function with my tuples. I tried ; void foo(T...)(T tuple) void foo(Tuple!(dchar,uint) tuplle) But even couldn't compiile. Do you have any idea for passing result of std.algorithm.group() to my free function?

Repro:
struct A {
@property foo() { return 42; }
}
This is correct code, the fact that foo is a function is inferred from the
presence of @property, and the return type is deduced automatically from the
body. However, if a .di file is generated it'll have this code:
struct A {
@property foo();
}
which is incorrect D.
Solution: keep the bodies of functions with automatically inferred type in the
.di file.

Obvious in retrospect. Repro picked from std.array:
inout(T)[] overlap(T)(inout(T)[] r1, inout(T)[] r2) @trusted pure nothrow
{
alias U = inout(T);
static U* max(U* a, U* b) nothrow { return a b ? a : b; }
static U* min(U* a, U* b) nothrow { return a b ? a : b; }
auto b = max(r1.ptr, r2.ptr);
auto e = min(r1.ptr + r1.length, r2.ptr + r2.length);
return b e ? b[0 .. e - b] : null;
}
After .di generation:
pure nothrow @trusted inout(T)[] overlap(T)(inout(T)[] r1, inout(T)[] r2)
{
alias U = inout(T);
static nothrow U* max(U* a, U* b);
static nothrow U* min(U* a, U* b);
auto b = max(r1.ptr, r2.ptr);
auto e = min(r1.ptr + r1.length, r2.ptr + r2.length);
return b e ? b[0..e - b] : null;
}
Obviously that's not going to work for more than one reason :o).

Originally (.Net 1) there was only 'Parse', 'TryParse' came in .Net 2, I guess they had to admit that exceptions are not always practical. I think TryParse (and anything marked prefixed with Try) is meant for quick stuff. It doesn't return any error. Just a boolean indicating that it failed. The entire function seems to be a wrapper around the actual try mechanism. So Parse will give you an error, TryParse will just tell you it failed.

According to group()'s documentation, the elements of the range are
Tuples (not the range itself). Best thing to do is to use a template and
optionally require that the elements are instances of the Tuple template.
import std.stdio;
import std.algorithm;
import std.typecons;
import std.traits;
import std.range;
void foo(R)(R range)
if (isInstanceOf!(Tuple, ElementType!R))// -- optional
{

}
void main()
{
int[] arr = [ 1, 2, 2, 2, 2, 3, 4, 4, 4, 5 ];
foo(arr.group);
}
Prints
Tuple!(int, uint)(1, 1)
Tuple!(int, uint)(2, 4)
Tuple!(int, uint)(3, 1)
Tuple!(int, uint)(4, 3)

BLAS and LAPACK (or variants on them) are low-level matrix math libraries that many higher-level libraries call. Few people actually use BLAS directly. So, clearly, not every matrix math library is the same. What differentiates BLAS from Armadillo is that you can be far more productive in Armadillo because the syntax is friendly (and quite similar to Matlab and others). There’s a reason why people use glm in C++. It’s probably the most productive way to do matrix math with OpenGL. However, it may not be the most productive way to do more general matrix math. That’s why I hear about people using Armadillo, Eigen, and Blaze, but I’ve never heard anyone recommend using glm. Syntax matters.
