digitalmars.D.learn - Clearly Label D1/D2/Tango/Phobos

D1/D2/Phobos/Tango and not just really poor unvetted tutorials.  
It would really be helpful if those providing references, code 
snippets, tutorials, etc clearly identify the context (i.e 
D1/D2/Phobos/Tango).  I just think it would help accelerate the 
spread and acceptance of this language if more of the code worked 
as listed.

If people are out cruising the web and download a fresh copy of D 
with excitement (about a cleaned-up, updated c-type systems 
language) and then the first several things don't compile w/o 
errors, they're going to move on.

Thanks so much to all who provide references, tutorials, etc!  It 
is great service in helping others learn.  I hope this is seen as 
constructive criticism for that is what it is.

Hi !

It's simple: use D2, and forget about Tango.
D1 is deprecated and its maintainance will be stopped by the end of the
year. Noone should be starting with D1 now.

You can start here:

I cleaned up this page a little bit, I hope this helps.

dlang.org is the official source for the current version of D.

Unfortunately there isn't really a way to "deprecate" the D1-specific
tutorials floating out on the web right now... we could do with more
publicity for dlang.org and other up-to-date D sites, though.

You can also take a look at:
http://ddili.org/ders/d.en/index.html

This is a "in progress" English translation of a Turkish book to learn D2=
 from scratch.

You can read it on-line, or download the pdf file.

What's wrong with Tango? It works with D2 and you can have it side by 
side with Phobos. The XML library in Tango is superior to the one in Phobos.

I tried one "file open" example from this site and one from 
another site and neither compiled w/o errors.  I thought perhaps 
I had copied some code that might have been related to a specific 
version of D.  I was just commenting that for people who are 
supplying exmaples/tutorials it would help if they specified more 
clearly what version/genre of D their code sample works with.  I 
have no opinion on the Phobos/Tango or deprecated 
features/version stuff.  I just think it would help the 
acceptance of the language if stuff compiled as listed.

As for the example from this site under std.stdio; it should 
compile.  It's a simple program.  This is the mother site.

A member helped me realize that it needs "import std.stdio;"


// test.d
void main(string args[])
{
     auto f = File("test.txt", "w"); // open for writing
     f.write("Hello");
     if (args.length > 1)
     {
         auto g = f; // now g and f write to the same file
                     // internal reference count is 2
         g.write(", ", args[1]);
         // g exits scope, reference count decreases to 1
     }
     f.writeln("!");
     // f exits scope, reference count falls to zero,
     // underlying FILE* is closed.
}

This is a documentation bug. Please file an issue in the bugtracker so
that this can be fixed.

All code examples in library documentation should compile without errors
as-is,  unless they are incomplete snippets, in which case they should
compile in the intended context with no further modifications. If
something doesn't compile, the documentation is faulty and needs to be
fixed.

<snip>

Even the particular version of (DM)D in which it has been tested, given how
much the 
language has been changing.  There have been language-level changes to D2 very
recently, 
and bug 1824 is one of probably many that still need to be dealt with before it
can stabilise.
