OT: Tiobe Index - December Headline: What is happening to good old language C?

[Nick B via Digitalmars-d]

The programming language of all programming languages C is 
consistently going down since November 2015. The language was in 
a range of 15% to 20% for more than 15 years and this year it 
suddenly started to suffer. Its ratings are now less than 10% and 
there is no clear way back to the top. So what happened to C? 
Some months ago we already listed some possible reasons: it is 
not a language that you think of while writing programs for 
popular fields such as mobile apps or websites, it is not 
evolving that much and there is no big company promoting the 
language. May be there are more reasons. If you happen to know 
one, please share it with us.

That'd be great, drop in to our gitter some time

My unscientific, anecdotal experience with reddit is that the first post, 
written well, will spark positive interest and discussion. It's really the same 
thing you already did when you posted the link to the n.g.


A negative first post will frame everything negatively afterwards. We shouldn't 
leave this possibility to chance. First impressions matter here as much as anywhere.


No first post often results in nobody ever commenting on it. If I see a topic 
with no posts, I think "why waste my time commenting here, nobody cares about 
this and nobody is looking at it."


If a title alone is good enough, movies would not be marketed with trailers, and 
books would not have a back cover.


If you're writing first posts that get downvoted, I suspect that concluding that 
first posts are a bad idea may not be correct. Maybe it just needs to be a 
better first post :-) Next time this happens, please ping me or Andrei and maybe 
we can help.

It should be as simple as a linear find (over the range of

Hmm not sure that will work.

The annoying property of this problem is calculating .empty and 
having .empty not mutate the ranges. however if you settle for an 
eager empty something like


auto setIntersect(RoR,alias _pred)(RoR ror) if (allSatisfy!(RoR, 
isSortedRange!_pred) &&
  
allSatisfy!(RoR, isSame!(ElementType) &&
 
!allSatisfy!(RoR, isRandomAccessRange))

{
enum lengths = RoR.length;

alias pred = BinaryFun!_pred;
struct SetIntersect

RoR ror;
elem[lengths] fronts = void;
elem front = void;

While it may be too late to redeem Phobos and its handling of 
arrays as ranges, it is worth noting that in the library I've 
been working on the `isRange` template behaves like you're 
expecting. In mach, `front` and `popFront` and `empty` are not 
defined for strings; rather, functions that accept ranges also 
accept types that ranges can be made to enumerate, including 
strings and other arrays.


If you really wanted an `isInputRange` that behaves like you're 
wanting, it's only a 6 line template that you would have to 
interject in your code.


enum bool isInputRange(T) = is(typeof({
T range = T.init;
if(range.empty){}
auto element = range.front;
range.popFront();

Random covers C++11 random number generation for example.


If D code can be compiled into a common C libraries like Mir

Currently it is possible only with LDC (requires some

My main problem is that now I am looking for industry 
placements, it is clear that in this field C and C++ are highly 
desired. I have used C++ prior to discovering D, but much of my 
learning curve has occured while using D, and I feel quite 
comfortable using it. Using D makes me look back at what a 
great language it is compared to C++ (I know it can also be 
compared to C but I haven't used C).


So I don't want to go back. It isn't as if I have a career in 
C++ (like I know some people here have) and use D (only) for 
pleasure so I have no real knowledge of how things I write in D 
compare to what I would do in C++ (and none whatsoever for C).


Does anyone have any advice for me? Obviously I'm going to have 
to make this leap and the organizations will have their own

Failing that, think of this as another one of those 'D is

I'm an academic, so no useful advice. I was reminded when reading 
your post of all the comments from Lisp, Scheme, Haskell, and 
[insert language] users that are able to choose their language 
for much of their job. Many use Lisp. Just not for production. An 
advantage of D is that you can mix C/C++ with D, so that 
increases the chance of using it.

This might not be usefull for ure current usecase but if you want 
a property to behave like a field, it has to be a field.
So a boxed type might be better depending how much you want to 
manage.

Here are some property like examples:

   struct Prop(T)
   {
  private T value;

  alias opCall this;
  ref T opCall() { return value; }
  ref T opCall(T val) { return value = val; }
  string toString() { import std.conv: to; return 
value.to!string; }

   }

   struct ReadOnly(T)
   {
  private T value;

  alias opCall this;
  T opCall() { return value; } // return a copy
  string toString() { import std.conv: to; return 
value.to!string; }

   }

   struct WriteOnly(T)
   {
  private T value;

  void opAssign(T val) { value = val; }
  string toString() { return typeof(this).stringof; }
   }

// alternative write only so you can chain opCall 
writeOnly(33)(56)(66);

struct AltWriteOnly(T)
   {
  private T value;

  ref typeof(this) opCall(T val) { value = val; return this; }
  string toString() { return typeof(this).stringof; }
   }

   struct FunProp(T) if(isSomeFunction!T)
   {
  private T value;

  alias value this;
  void opAssign(T val) { value = val; }
  string toString() { return T.stringof; }
   }


   class Test
   {
   Prop!int someVal;
   ReadOnly!string name;
   WriteOnly!int someOtherVal;
   FunProp!(void delegate(int)) funProp;

   this()
   {
   name.value = "Test";
   }
   }

   void main()
   {
   auto test = new Test;
   test.someVal = 66;
   test.someVal++;
   test.someOtherVal = 100;
   test.funProp = (int i) => i + test.someVal;
   test.someVal.writeln;
   test.name.writeln;
   test.funProp(33).writeln;
   test.funProp.writeln;
   test.someOtherVal.writeln;
   }

haven't done extencive tests with them but they can be used as 
builing blocks, you can add other operator overloads to manage 
other access to the value.

you can build better properties without @property :/

On arch linux there should not be any issue. Archlinux does not

Thanks for the tip. I haven't done a lot of development on linux

Having said that, from the arch wiki:

Looks like there is a hardening-wrapper which forces PIC by 
default. As clang worked just fine I assumed that was the actual

There are several issues related to the nsis-based windows installer

Programming an installer is a small job but it has a long term impact
on the user experience. Worth 100€ imo.


Any particular reason to use Inno Setup over for example Wix Toolset?



In my last job I worked on installers (which I didn't like but someone 
had to do it.) I recommend WiX over Inno. The main reason is that WiX 
produces an MSI and Inno doesn't. An MSI is just a data file, not an 
executable, and is thus better for security. I normally wrapped the MSI 
in a bootstrap exe. But we had one customer that was part of the 
government and wouldn't accept anything but an MSI.
If you want, you can generate the XML with a program. I just didn't 
because I figured it was easier to modify if you can directly see the 
XML. My install builder was actually a combination of C# and WiX. I 
never found scripts to be flexible enough and it's just one more 
language to know.

[Semi-OT] I don't want to leave this language!

[e-y-e via Digitalmars-d-learn]

Currently I have been learning D for about a year and a half. 
This may seem like a short time, but this is the longest I have 
stuck with any language. I have only been learning for 4 years 
and I am currently in university studying first year of computer 
systems engineering.


My main problem is that now I am looking for industry placements, 
it is clear that in this field C and C++ are highly desired. I 
have used C++ prior to discovering D, but much of my learning 
curve has occured while using D, and I feel quite comfortable 
using it. Using D makes me look back at what a great language it 
is compared to C++ (I know it can also be compared to C but I 
haven't used C).


So I don't want to go back. It isn't as if I have a career in C++ 
(like I know some people here have) and use D (only) for pleasure 
so I have no real knowledge of how things I write in D compare to 
what I would do in C++ (and none whatsoever for C).


Does anyone have any advice for me? Obviously I'm going to have 
to make this leap and the organizations will have their own 
ecosystem but while I'm learning how can I replace some of the 
great things about D? Things like built-in unittests, sane static 
if, painless CTFE, ranges, or even just the DUB package 
manager/build tool.


Failing that, think of this as another one of those 'D is great!' 
posts ;). And whatever happens, I'll certainly try and convince 
my host company to use it...

Actually, I think I may know the problem with the access denied 
bit, it's too late for me to test now but I will test tomorrow.  
My D source code and the GLFW3.dll library are stored on a Linux 
file server (I am using D in Eclipse on a Windows 10 machine), so 
perhaps there is some issue with the FileServer denying access to 
certain things, so I will investigate if moving the source and 
the dll to my local machine will remove this issue, I will post 
here the results.

DUB works on Windows just fine. My question is, why are you

There are several issues related to the nsis-based windows

Fall with a virus false detection may happen again. "Braddr" 
proposed to handle digital signatures in case it would 
involve payment.


Programming an installer is a small job but it has a long 
term impact on the user experience. Worth 100€ imo.


Any particular reason to use Inno Setup over for example Wix 
Toolset?


D has `extern(Pascal)`, which means the the new setup program 
could be mostly coded in a D dll used by the innosetup script.

java) but I really like D as a language, and want this interface 
to be written in it.

It'll want to go through a few polish iterations before I even 
think of doing that; and it'll need support for things like 
toString/toHash/etc.


Another critical bit of functionality that std.bitmanip provides 
that I currently don't is a bit array. I also want to support 
statically sized bit arrays, Phobos only provides support for 
dynamically sized.

The order of libraries makes error in dub

[unDEFER via Digitalmars-d-learn]

Hello, dub makes string like the next to compile my program 
(WS_32.LIB at the beginning):


$ dmd -m32mscoff -lib 
-of.dub\\build\\library-debug-windows-x86-dmd_2072-83D2723917096513EB360761C22DDD87\\db.lib -debug -g -w -version=Have_bdb2d WS_32.LIB libdb53d.lib source/berkeleydb/* -vcolumns

Error: Error reading file 'WS_32.LIB'

So it shows error.

In other order (libraries at the end):
$ dmd -m32mscoff -lib 
-of.dub\\build\\library-debug-windows-x86-dmd_2072-83D2723917096513EB360761C22DDD87\\db.lib -debug -g -w -version=Have_bdb2d -Isource source/berkeleydb/* libdb53sd.lib WS2_32.LIB -vcolumns


No error.

But (again WS_32.LIB at beginning):
$ dmd -m32mscoff WS2_32.LIB libdb53sd.lib 
transactions_test/writer source/berkeleydb/*
LINK : warning LNK4098: defaultlib 'LIBCMTD' conflicts with use 
of other libs; use /NODEFAULTLIB:library


Again no error, only warning.

How to make with dub correct compilable compile line?

There are several issues related to the nsis-based windows

D has `extern(Pascal)`, which means the the new setup program 
could be mostly coded in a D dll used by the innosetup script.

[D.Rex via Digitalmars-d]

Hi,

I am sure this has been asked a thousand times before, but can 
anyone link me to a tutorial on how to set up derelict and GLFW3, 
I am trying to work on a project and I just can't get it set up 
regardless of how many times I read the derelict readme's.


Also, if anyone knows of any good tutorials or ways of creating a 
flow-graph editor similar to blender's flow-graph editor 
interface I would greatly appreciate a link or some assistance, I 
have a rather large project I am working on which I would love to 
do in D and requires a flow-graph GUI much like blender's.


Cheers!

It will with -w. And even if you build with -wi, it's bad practice to leave
warnings in. So, really, we should _never_ warn about anything where it
would be reasonable for the programmer to not fix whatever is causing the
warning.

That being said, if we're dealing with something that is clearly never okay,
a warning is fine. And I don't know how anyone can claim that doing
something like ++x on a variable that was initialized with null or void is
rasonable. But if such a warning were introduced, it would have to be done
carefully and only used when it was totally certain that what the programmer
was doing was invalid. For instance, taking the address of the variable or
passing it to a function would potentially be perfectly fine, whereas
calling a member function on it when nothing could have possibly given it a
value wouldn't be.

Java sometimes gets annoying with how it requires that you initialize a
variable before you use it, because its detection simply isn't smart enough,
and we don't want to get into a similar boat with D. So, if such detection
really _is_ smart enough, then fine, but it should never have false
positives, or it's making things worse than they are now.

not now, but it looks like needless limitation. any void

zeroes" in CTFE engine.


On the contrary. If something is NOT initialized, it uses its 
default (e.g. zeroes), but if it is =void it should be an error 
to use it before any assignment.

Re: How to use library compiled with Microsoft Visual Studio 2015 in D?

OK, I have found. It must be library WS2_32.LIB from Microsoft 
SDK. But dumpbin doesn't show __imp__htonl@4 symbol there. The 
magic!

Thank you!

it will: all my projects are built in "-Werror" mode (the only

unreachable" -- it is completely useless for me).


i'd prefer to have `pragma(warning/info, msg);` instead, so i can 
issue informational messages when i want to.

Big thanks! -m32mscoff is great!
But now I have the problem of unresolved external symbols, e.g. 
"__imp__htonl@4".
What I'm doing? I'm going to Microsoft Visual Studio directory

$ for i in `/bin/find.exe . -iname "*.lib"`; do bin/dumpbin 
/SYMBOLS $i | /bin/grep __imp__htonl@4 && echo $i; done

./atlmfc/lib/uafxcw.lib
3D6  UNDEF  notype   External | __imp__htonl@4
./atlmfc/lib/uafxcwd.lib

Try to link with found libraries, but it doesn't work. The 
symbols still unresolved.

What I'm doing wrong?
