I'm revisiting this because I now have had the chance to look at the various libraries and IMHO the "really awesome, 100% complete library" depends on the users' goals and their definition of awesome and complete. Aside from ddbc which is like ODBC/JDBC and thus supports multiple db's (not my interest), I've found five Postgres-specific libraries worthy of further exploration: 1. derelict-pq. This is the most downloaded one and is simply a binding over libpq, so AFAICT it's nearly 100% complete. It's also well-documented, in part because the Derelict libraries provide overall guidance, but mainly because a D user can refer directly to the comprehensive libpq documentation and (C) examples. The only strange fact is that it's been stuck in a beta.3 release for the last five months. 2. dpq2. Second most downloaded and built on top of derelict-pq. The "documentation" consists of a README listing the features and a single example, which appears to focus on support for JSON/BSON. 3. vibe-d-postgresql. Third most downloaded and built on top of dpq2. Docs consist of a single example program. 4. ddb. About the same number of downloads as the above. Implemented on top of front/backend protocol. No documentation although repository has a folder with two sample programs. 5. dpq. Implements its own wrapper over libpq and has some ORM functionality. Docs are a README with example program. The main issue is that, other than derelict-pq, using any of these libraries involves reading the library code and understanding the sui generis interfaces implemented by each. I'm new to the D community, but coming from Python, the contrast is significant. First there is the well-documented PEP 249 (https://www.python.org/dev/peps/pep-0249/) promulgated by the Python DB-SIG (and note that 249 is v.2), which led to the implementation of psycopg (also well-documented including various extensions to the API) and many other adapters to Postgres and other databases. Some developers spend hours writing code but don't feel the need to speed minutes documenting or at least showing how to use their code. Part of the reason others roll their own (one they will understand). Goes on and on. If its for their personal use, then they shouldn't put it on dub to saturate the ecosystem. I sometimes go around sending pull requests to some with sample I got from their unittests or "example" folder. Worst case, they send you a link to the C library they wrote bindings for... "oh its easy to know by looking at the C docs". Some don't even border... this is common with C libraries. C has libs but hard to figure out how to use without going through code. Laugh at, as one may, Javascript npm libraries are well documented so there's high adoption. OP even agrees derelict-pq is well documented so it has a higher usage. All Dub libraries with good docs are those that are downloaded. Most importantly, a description of package and a sample/demo is the README.md file. A link to generated docs may follow to more info. Only generated docs don't cut it. If you document your code well, others will use and contribute to it without rolling their own. Docs on library purpose and sample usage at least. "The most used Dub libraries are those well documented." +1 I want to subscribe to this. To improve the D ecosystem it would be a plus point to mark all libs at code.dlang.org having documentation with a special sign. Most people want a solution for their problems, they don't want to make an analysis, which of n available libs is best to use. Most more widely adopted languages offer the needed DB connectors in their std. The medium step between expanding the std lib and having nothing official might be, to try to adopt more for the dlang git repro. (https://github.com/dlang-community) (As mentioned before) Even if the first choice might be not the best of all available libs for one problem, if the community has started to develop _one_ solution for a problem, the value of contributing to this increases dramatically. I think the community is not big enough to support five different well documented, well designed and understood libs for solving the same problem. Regards mt.

Has any body taken a look at monetdb?
An old friend of mine is working in the database research group in Amsterdam, they have developed monetdb: From https://www.monetdb.org/Home The column-store pioneer The column store technology of MonetDB has found its way into the product offerings of all major commercial database vendors. Its pioneering role has been internationally recognized with the prestigious ACM SIGMOD Edgar F. Codd Innovation Award and ACM SIGMOD Systems Award. The market for applications empowered by these techniques provide ample space for further innovation, e.g. as demonstrated by our ongoing projects. At the same time, the landscape for major innovations remain wide open. A peek preview is given in the award winning paper titled: The Researcher's Guide to the Data Deluge: Querying a Scientific Database in Just a Few Seconds. I just found that there everything is now on Git hub, with clients written for: Ruby, Perl, PHP, Python and Java. https://www.monetdb.org/blog/monetdb-on-github I just took a short look into the Ruby client code, I have not used Monetdb yet, but is there anybody interested in trying to make a D client? I think it might give an interesting storage concept especially for people using D for Big Data. Any comment? Regards mt.

The OP wasn't looking for other benefits of the template version other than argument checking and didn't consider the downsides either. So maybe there is room for improvement using runtime arguments. So let's add some features: 1) compile-time "in" contract, run on the argument list 2) functionality to promote runtime arguments to compile-time This was the more precise question: How to "promote runtime arguments to compile-time". I forgot the exact error, but it was during using vibe.d, that there was an error popping up at runtime, which I thought should have been detected as simple syntax violation already during compile time. Making me feeling for some seconds being back at .php. :) I think it was in a regex, where the use of ctRegex would have prevented me from the runtime error.

In theory, you could write your code so that it's easy for the optimizer to prove that you're only using 8 or 16 bits and variables would fit in single registers, so you would be able to get away without a performance penalty for using a language where ints are 32-bit. Ah, that makes sense. Thanks for clarifying. For me it hasn't proved a problem, but I could see it being if you do a lot of arithmetic with 16-bit integers. I just want to point out, that my impression is that the maker scene using all this 16 bit Arm Arduino and what ever micro controllers, would be happy to have D as an alternative for coding in C.

I think this is a very pragmatic analysis of the main roots of the problem, which clearly explains why D remains much less popular than Go, Python, Kotlin, etc despite the language itself is at least as modern and convenient (and even more IMHO). I don't think the situation will change any time soon, so I feel exactly in the same mood as you. Hence my suggession to simply make a few "cosmetic" changes to change D's perception on the web, to compensate for the lack of money and manpower. But they won't probably be applied. And I know that for the "do it yourself" I'm probably part of the problem... I understand the frustration, brilliant language but not so well designed ecosystem around. Please be aware, that even the setup of the D Foundation is still work in progress. So we are still waiting for the foundation to offer some kind of supporting memberships. But as Andrei A. told us on DConf, the foundation already is paying some students (a small salary) for their work. So best thing we can do is to push the D Foundation (Andrei+Walter) to optimize the support structure. The good thing behind these obvious missing parts is, that there is a strong focus on the language itself, so I am convinced, that D is here to stay, so that every effort in learning the language is a well made investment.

Also, it only works if you're just sending the string to
writeln. It doesn't help the general case :(
you can define:
auto mixinter(string x)(){return mixin(interp!x);}
(in the same scope as the vars used inside x)
And use:
string text = mixinter!"${name} and this are app ${age*365*24}
hours!";
But can someone explain me why this works:
import scriptlike;
void main()
{
auto name = userInput!string("Please enter your name");
auto age = userInput!int("And your age");
// The proposed notation for scriplike string interpolation
writeln(mixin(interp!"${name} you are app. ${age*365} days
old"));
// with exho definition
auto exho(string x)(){return mixin("writeln("~interp!x~")");}
exho!"${name} and this are app ${age*365*24} hours!";
}
and this not?
import scriptlike;
// with exho definition outside the scope of the used vars
auto exho(string x)(){return mixin("writeln("~interp!x~")");}
void main()
{
auto name = userInput!string("Please enter your name");
auto age = userInput!int("And your age");
writeln(mixin(interp!"${name} you are app. ${age*365} days
old"));
exho!"${name} and this are app ${age*365*24} hours!";
}
Can it be possible to allow a function to be defined outside the
scope of use to return a "mixin object"?, than everything can be
done in a lib outside, no need to add parsing complexity to the
language?

You can just write:
exho!"The number ${num} doubled is ${num * 2}!"
It requires 'num' to be available to the exho function
definition so will not
work in the general case.
Thats a pity, so shouldn't we than try to find a way to define a
alias like 'shortcut'
for something like
mixin(compiletime_expresion!var)
so we can write just
shortcut!var ?
Or what about defining a new return type for functions allowing
them to return a mixin even if defined in a lib? (Because the
code above is allowed but only working if exho is defined in the
same scope as the var 'num'.)

Yea, and note, I'm still open to the idea of better names than
"interp". I'm still not entirely happy with that name. I'm even
half-tempted to use "_".
The only one problem I've found with doing it in library
though: Far as I could tell, it seems to require the caller
uses string mixins, which makes actually using it a little
uglier and more verbose than I would like.
I was trying to get it shorter:
// From

int num = 21;
writeln( mixin(interp!"The number ${num} doubled is ${num * 2}!")
);
defining a new method exho! (derived from echo + mixin...:-)
auto exho(string x)(){
return mixin("writeln("~interp!x~")");}
You can just write:
exho!"The number ${num} doubled is ${num * 2}!"
This now looks more like "normal" scripting than
writeln( mixin(interp!"The number ${num} doubled is ${num *
2}!") );
Maybe I'm overlooking something obvious, but I haven't been
able to find a way to change it to either a template mixin or
even just a plain template without sacrificing to whole point
of interpolated strings: specifying the arguments 100% inline.
What I think would be ideal is a language enhancement to allow
"interp" to do its job without the extra syntactical noise.
That would not only give us good interpolates strings, but
would likely have other applications as well.
I am not against the idea making string interpolations part of
the language, in vibe.d diet templates the extrapolation is
marked with #{var}, the ruby style, I like this too.

Learning programming with D - optimizing the entry point / the environment?
Hi, after a year of learning D and using it for some small projects. I think "we" should offer a Starter Kit like bundle designed to learn D. My inspiration is from the Basic256 http://www.basic256.org/, to have something similar for D, you would not need an complete IDE, but it would be nice. My last idea was, what about enhancing DUB to support the installation process of the different D compilers, (with DMD as default)? So if we get DUB as free software in Debian -> Ubuntu & CO. You have just one starting point (installing DUB). Then a special option might be to install(download) the existing set of tutorial examples to explore the language. Very important I think would be to add some graphics, especially to get the interests of kids, For example arsd.simpledisplay.d with its nice learning example Pong. What do you think about this?

The second thought is: When you get the power of vibe.d inside mysql, than everyone who is using mysql could use vibe to do the dataset rendering and by this you may speedup every system using mysql without having to change the complete front end to vibe allowing a smooth migration.

String symbols are Ruby's(and many Lisps', and maybe some
other, less popular languages) way to do untyped enums and
untyped structs. It's a dynamically typed languages thing and
has no room in statically typed languages like D. D mimics
dynamic typing to some extent by creating types on the fly with
it's powerful templates mechanism - but a new type still needs
to be created. D is geared toward reflection on types at
compile time, not towards type detection at run-time...
Thats true.
Allowing something like `auto params = [:y : 50, :x : 100]`
won't really solve anything. It works nicely in Ruby, because
Ruby has dynamic typing and with some syntactic sugar you get
elegant syntax for dynamic structs. But in a structured
language like D, you run into the problem that `[:y : 50, :x :
100] is an associative array with a determined type for it's
values, so you can't do things like `[:y : 50, :x : "hello"]` -
which greatly limits the usability of this syntax.
Yes.Ok.
What I like about the :symbol notation is, that a string witch is
used
only to distinguish between different objects in an Hash / AA has
a complete different
purpose than a string used to be displayed for the user.
I think that
writeln("Name", a[:name]); is easier to read, than
writeln("Name", a["name"]);
especially if the structures are getting bigger, or you are in a
vibe.d jade template string where you would have to use
additional quoting to write:
a(href="a[\"url\"]") a["link_text"]
a(href="a[:url]") a[:link_text]
May be I should get rid of this by using a struct for my mysql

Hey all,
I wanted to relive the discussion on named arguments and ping

There is a bunch of examples to show how needed a unified
solution for this problem is, let me give you one from phobos
[2].
```
// I want to allow downsizing
iota(10).sliced!(Yes.replaceArrayWithPointer,
Yes.allowDownsize)(4);
```
There is of course the alternative solution that an author
overloads his function to the utmost, but this results in
complexity and duplicated code (see e.g. redBlackTree in phobos
[3]).
Currently the best solution AFAICT is to use a struct to pass
such flags, like
```
struct Options{int x; int y=1; int z=2;}
auto fun(Options options)
{
return options.x + options.y + options.z;
}
Options options = {x: 4, z: 3};
auto a=fun(options);
```
There are also other workarounds as discussed in [1] (e.g. with
CTFE string analysis [4]).
I general there two solutions to this problem
1) get true named parameters support in D (probably complicated)
2) allow struct inits in functions - e.g. fun({x: 4})
For 2) Jacob Carlborg has proposed something similar three
years ago. In his case he proposed anonymous structs which
might be more generally applicable, however just created the
struct seems easier and allows more
It doesn't seem that complicated to me as the compiler already
knows the type of the argument.
Using structs is not ideal, because one can't require
parameters, but this can be solved by having those parameters
as normal ones like `sliced(4, {allowDownsize: true})` and it
creates some maybe unnecessary overhead.
However it is probably the easiest solution right now.
What are your thoughts on this issue?
On a side note: many templated functions are also complicated
and experiencing this issue, so it also might be worth to think
about this issue too ;-)
Cheers,
What about this idea? A new word "as" or something similar.
You have defined:
int fun(int x=100, int y=100, int r=100){...}
int xpos=100;
int ypos=100;
int radius=50;
Now you are allowed to call:
fun(xpos,ypos,radius); // normal nothing has changed!
Call with "as":
fun(ypos as y, xpos as x, radius as r); // different order!
or
fun(radius as r); // defaults values are used.
<=>
fun(,,radius);
The compiler is looking for the right mapping?

I like the "Vertical Split" option in general, but I dislike to have it on the Index Page, So I am very much in favor for changing the behavior of the "View Modes" in this direction. What do others think? Regards mt.

If the D community wasn't spread out: economic/scientific, games, web, hobby, professional, educated, non-educated... There tends to be contention between those that want to see D strive to become a potent system level programming language and those that want to see D become a convenient compiled scripting language. Trying to move in both directions at the same time is bound to lead to a net slow down in progress IMHO. Ok.

There are many corners. Some, like the corner of compiled languages with automatic memory management and high level features have moved a lot in the past few years (Swift and Go). It is gone. There is no way for D to catch up with Swift and Go. May be, I did not start to learn anything about these languages yet, so I just looked on the Wikipedia pages, and I am not convinced. Why? Syntax not C compatible, but for me this is a very strong argument, because everybody is defining his own similar elements and after "learning" some Languages (Basic,Z80Asm,Pascal,Comal,Prolog,(x86Asm),C,C++,Perl,Php,Ruby (RoR)) I am quite happy, that D offers a 'known' syntax. And the opportunity to use it for scripting - compiling very fast (#!-rdmd Execution). By learning D, I can write a super fast web applications (vibe.d) + stand alone programs for any purpose and even do scripting tasks. Is there any other language candidate offering the same? The other corner, taken by C, C++ and now also Rust, moves a lot slower and is in some areas incapable of moving. So I think the current focus on interfacing with C++ is the right focus, just keep focused on it. D needs to reach parity with common C++ features and then do it better across the board. Sounds right. [...] And a special second list, where people can vote, which topic of D (language or environment) need to be improved most? The historical challenge for D is a tendency to spread out. Voting is no good, it takes away focus. Then you are back to hunting down many corners, and D will remain one step behind. The voting purpose is exactly to see what are the improvements really needed, to get this focus. I think, it is not so useful, that there are already min. 4 different DUB modules to access MySQL/MariaDB).

D has been around the corner for a D-ecade. The corner is constantly moving so that is obviously not a winning strategy. If something is around the corner, you must know! So I got it via this: http://www.heise.de/developer/meldung/Programmiersprache-D-Compiler-ist-jetzt-selbst-in-D-geschrieben-2869589.html The most read IT News Ticker in Germany, pointing to D, saying that the D compiler now is written in D, and what made me interested, the reference to C++ and Ruby. So I started to read Wikipedia and in the end I gave it a try. What about making a special voting list/page, where every one registered to the forum, can put in, why he/she is using D and vote for other arguments giving + or maybe - points. And a special second list, where people can vote, which topic of D (language or environemt) need to be improved most?

Oh, I am sure I caused it myself, I am new on D and all my searching for it and than Bang ! :-) So, don't try to understand Tiobe, just be happy D is a new entry for top 20, and work hard to improve DMD, GDC, LDC, DUB, vibe.d etc... to make this real cool programming experience open for more people.

How to simplyfy "getting started" ? Installation desciption at dlang suboptimal.
As an new D user but old Linux/Ubuntu user, I am used to install nearly everything which is possible via sudo apt-get install, so I searched for "Installing D with Ubuntu", because I didn't wanted to use the package link offered on the website dlang.org. I came to: http://d-apt.sourceforge.net/ where the additional hints to dub and gtkd are very usefull. (Not mentioning what can be done via dub) And here: http://ljdelight.com/installing-dlang-dmd-dub-on-ubuntu/ the layout is better and libevent-dev libssl-dev for vibe.d are mentioned, too. So making an update at dlang.org, with a optimized page where all of the most important elements are described and in which order it is best to install would still be useful. I think probably the best would be if "sudo apt-get install dmd/dub", out of the box would deliver, without the need to use an external repository which, is not included as default in Debian/Ubuntu. Does anybody know how to form a "petition" for getting the always latest stable releases of D included in Debian (=>Ubuntu)? Regards Martin T.

D rose again from 23th to 21th! http://www.tiobe.com/index.php/content/paperinfo/tpci/index.html The rating is now more than 1% same as many other languages in the ~15+ range. Explore the history here: http://web.archive.org/web/20150101033933/http://www.tiobe.com/content/paperinfo/tpci/index.html?lm:1417992224 Its an quite interesting. regards mt.
