Dear D community

The first public release of Tango is now ready for download.

Tango is a D library that provides a runtime for the D programming language,
plus many additional library features for the D programmer. Further growth
and sharpening of quality is expected for coming releases.

A feature list can be found on
http://www.dsource.org/projects/tango/wiki/Features

Extensive work has been put into documenting the basic features, and in
trying to make usage and installation easy for as many as possible.
Platform support will be provided with the help of the users. Win32, Posix
x86 and PPC have currently received most testing.

Tango is not yet fully polished, but the last few weeks have seen efforts to
solve toolchain problems, cleaning operations, documentation production, an
improved website and more. Hopefully you will find it a useful addition to
the D world, and feedback will gladly be accepted.

The Tango homepage can be found at

W00t!  Looks fabulous, and right on schedule, too.  The future is 
looking bright indeed.

One thing I couldn't find browsing thought the docs: what's the 
situation with the GC?  Have Walter's type-aware additions made it in? 
Or is it still necessary to add manual "no_pointers_here" calls in the 
Tango GC to avoid scans non-pointer memory blocks?


One more question -- is there some kind of compile-time version check 
that can be used in code to determine if Tango is being used or not?
I suspect there's going to be a transition period here where people 
would like to support both Phobos and Tango for those who haven't bit 
the Tango bullet yet.

Yes, the "Tango" flag should be added to sc.ini (or equivalent) when 
Tango is installed. A Tango install which does not define the "Tango" 
version flag should be considered a broken install.

Yes.  Type-awareness was added as soon as the DMD bugs were sorted out.

Previously, Tango keyed on element size so the "no pointers here" calls 
still really weren't necessary as a default measure.  But with type 
awareness things are still obviously much improved :-)

The manual install guide suggests adding a "-version=Tango" to DFLAGS 
for DMD, and the equivalent for GDC.  And I believe the installers will 
take care of this for you as well.

Great.

Well, I'm concerned primarily with large blocks of floats and doubles, 
so I don't think the element size optimization would have benefited me much.

Great.  I see it now.

To Kirk -- if no -version=Tango flag means a broken Tango, then the 
wording on the Windows install page should probably be made a little 
stronger:
    http://www.dsource.org/projects/tango/wiki/WindowsInstall
It currently describes the flag as "optional".

In my view, if the flag is not mandatory, it is useless. (I want to be 
able to write code that relies on it.)

GUI is something that's being actively pursued.

There will be at least one Tango gui lib but it won't be in the core lib 
per se, since we intend to keep that 'tight' and 'agnostic'

Can you folks comment on what you see as the the transition plan?  The 
migration document does a decent job explaining how to convert from 
Phobos over to Tango whole hog, but realistically not everyone can make 
this transition overnight.  So anyone writing libraries intended for 
consumption by 3rd parties is faced with the options of
A) Port whole hog -- abandoning any users who are stuck with Phobos
B) Don't port at all -- annoying any users hoping to move to Tango
C) Port while maintaining compatibility -- annoying the poor me who has 
to deal with incompatibilities in the most basic functions (e.g. 
toString, writefln)


Option C) seems like the most logical.  And given that, it seems like a 
compatibility library would be helpful.  Some way to make it easier to 
write code that looks mostly like Tango code with a minimum of version 
statements, but which actually calls on Phobos at the bottom layers.

Or maybe I've misunderstood the options.  Given the new GC and new 
Object class it seems like any use of Tango with Phobos is radioactive 
and fraught with peril, but maybe its not so bad?  For example, can one 
use the io framework from Tango while still using Phobos as the std lib?

Anyway, I think a page on how to migrate from Phobos to Tango while 
mainintaining backwards compatibility would be of great use to library 
writers.

I and several others are trying to garner an effort to essentially port 
Phobos to Tango in such a way that most Phobos software could be 
compiled verbatim. This is the best option in my opinion, because it 
provides full backwards compatibility.

There already is the tango.phobos project at DSource which contains a "port"
of Phobos, although unsupported by the Tango team.

It has changed all std. to phobos. and been made to work with the Tango
runtime. There are a couple of catches with this version. Firstly,
threading is tightly integrated with the GC and as such the Tango threading
should be used, secondly it has afaik only (or mostly) been tested on Linux
and with DMD. 

What is there should be up-to-date with DMD 1.004, but no guarantees. Anyone
who wants to get involved are free to do so :)

I don't know that this is entirely fair--you paint the existence of 
Tango as annoying in three entirely different ways :-).  That said, code 
compatibility issues are (hopefully) not a long-term problem as people 
will either port their code or they won't.  What worries me personally 
about presenting option C as an official alternative is that it places 
us (ie. the Tango team) in a position of supporting a Phobos facade for 
a potentially indefinite period.


 Option C) seems like the most logical.  And given that, it seems like a 
 compatibility library would be helpful.  Some way to make it easier to 
 write code that looks mostly like Tango code with a minimum of version 
 statements, but which actually calls on Phobos at the bottom layers.


I think it would be more the reverse.  A library that looks like Phobos 
but calls Tango at the bottom layers.  But it's still a lot of code to 
maintain that has no direct relation to the project.  Perhaps such a 
thing could be created and managed separately?

I too wonder why those were changed. Why not leave them be? What's so 
terrible about toString? It returns a string, doesn't it? Furthermore, 
there's no toUTF16, toUTF32, so what's the point?

Seems like a change for the sake of being different.

Well, that's not entirely fair :)

You mention two specific areas:

1) writefln does not support the functionality we needed. It has no 
support for either Locales, or for indexing the arguments themselves 
(both for supporting I18N). We decided to go a different route, because 
we beleive I18N is important enough to warrant some direct attention. 
(locale is not quite fully enabled in this release, but it will be in 
the next one).

It would be cool if you ported the writefln code though, as an external 
option -- we can't expect I18N support to be to everyone's liking.


2) there's no toUtf16() and toUtf32()? This is not the case. Tango uses 
those in a number of modules to do just what they indicate. There are 
modules that expose all three ... in certain cases they're also 
templated for the base type that you want stored within (e.g. store as 
dchar, expose as all three types).

This really was a not an easy decision for us to take, as I'm sure you 
can imagine.

Tango is what it is, and yet is open to change too. There's a /lot/ of 
people involved as you can see on the site, and I do hope you'll give it 
a good look?

A noble cause, for sure, and I'm glad you did it. I just think that 
porting from phobos should be a no-brainer.

Obviously, I was talking about Object.toString. Changing Object creates 
unnecessary incompatibilities.

I definitely will. I, like most people, have been waiting for a general 
framework to appear and Tango is the best :) So far :)

Maybe my post was too harsh, I really appreciate the effort put in 
Tango. D needs Tango.

This was a difficult decision for us.  Technically, Object.toString 
doesn't return a string, it returns a char array (ie. a sequence of 
UTF-8 characters).  Thus, toUtf8 is a more meaningful term for what the 
method actually does.  Another reason we chose this route is because 
Tango has a string class, and toString suggests that an instance of this 
class would be returned.  I suppose it's worth mentioning, however, that 
toString support for structs has not been changed because it is a 
compiler feature, and the disparity bothers me.  Fortunately, toString 
isn't required for IO in Tango so the issue hasn't come up in practice.

This has been argued before on these newsgroups. It is a change for the sake
of consistency and correctness, nothing else, and Walter stated that this
would be a better solution, except that he finds the symbol ugly (!). Tango
does have a String class and I believe it would be misleading to return
d/w/char[] from toString in that case.

Good work guys! Keep going! :)

Even though I like Tango project, I would never abandon Phobos, because I like
Phobos simplicity (ie. it is not "too much OO"). As we discussed this many
times on IRC, many other people think this way.
Whenever I come to something I do not like in Phobos, I would either post some
suggestion to Phobos maintainer, or develop my own module which adds needed
functionality.
Tango is realy a GOOD and HUGE work, and as someone said previously - if You
realy want Tango as replacement for Phobos, You need to have all Phobos
functionality (ie. backward-compatibility), so Phobos users could use Tango
out-of-box.

 Dear D community
 The first public release of Tango is now ready for download.
 Tango is a D library that provides a runtime for the D programming language,
 plus many additional library features for the D programmer. Further growth
 and sharpening of quality is expected for coming releases.
 A feature list can be found on

I already installed tango from source on windows and I intend to use it as a

Although I just did some simple review and testing, it seems very promising.
The code looks very clean and structured. So I hope it will become the standard
lib for D.

Even selector is working on windows now. I mentioned it yesterday on irc and
today it's fixed, great :)

abnormal program termination

C:\Dprojects\tango>

--------------------------

main.d:

import tango.io.Stdout;

void main()
{
	Stdout.println("Hello world!" );
}

--------------------------

Any idea what caused this?


Also, reading the docs I have a few questions/complaints/critiques:

Why do I have to instantiate classes to do stuff like basic file/path 
operations?  I don't like having to keep track of classes and stuff when 
doing such trivial things.  Maybe there could be a procedural wrapper 
around this stuff?

Is there some simple way to get a start a timer that will either call a 
callback after some period of time or give you the time since it was 
started like in phobos' std.perf?

Is there any way I could make my programs that still use phobos compile 
again without uninstalling Tango?

The documentation uses 'auto' a lot.  auto is a cool feature, but now I 
have no idea what file.read; returns or how to deal with it.  Is it an 
array of (u)bytes (I hope!) ??  Is it something else that needs special 
care?  I suppose I could read the more exhaustive API index or even the 
source, but that would kinda defeat the purpose of a quick reference.


Questions/critique aside, Tango seems the best hope for a high quality 
and community driven standard library.  Thank you very much for your 
effort Tango team!

This is a bug in DMD but was fixed. Install the latest DMD version and try
again.

Yes; the Tango release is based upon a 1004 runtime model. You're using 
a 1.0 compiler? Imagine you'd find the same when using a 1.0 DMD 
compiler with a 1004 phobos.lib?




 
 
 Also, reading the docs I have a few questions/complaints/critiques:

That's possible, but usage of scope is handy here also? e.g.

scope path = new FilePath (...)

For many people, the advantages of keeping all the functionality 
together is a real boon.

Not yet. Want to write one?

 again without uninstalling Tango?


Yes, flip the phobos.lib file (or .a) back to the original one, and use 
the original -I setting. It's pretty easy, but might become easier if 
the compiler did not hard-code the lib name ("phobos.lib").

That's a good point. And at this time we don't have a quick reference 
per se [writes a ticket for it].

FWIW, untyped data in Tango is invariably returned as a void[], and the 
API links are pretty good even if the doc isn't always complete -- the 
doc API uses CandyDoc, and the big-blue-title at the top leads to a 
Decant generated source listing. All the other blue links on the 
CandyDoc pages lead to Wiki comments, which we'll uses for improving the 
code doc etc. Quite sophiticated really, for API doc :)

Yeah I was using a 1.0 compiler and the problem went away when I

For the rest of us, would you consider having a wrapper for that stuff

Sure.

Problem is though, I'm in a bit of time crunch with midterms,

able to even start for another week or so.  Is that OK?

Might I suggest that ubyte[] or byte[] be a more appropriate return type 
for some of those arrays due to the type-awareness of the GC?  It would 
suck to read in a "noisy" data file and have the GC choke on it, or have 
to always tell the GC that there are no pointers there.  I'm assuming 
you will never find valid pointers to memory in a file from a drive, or 
if you do, the GC probably wasn't scanning the file anyways so you'd 
have problems if you didn't already have a safety reference.

That would be great if it did. If a change were to happen there, it

Yes. There just wasn't enough time to doink all of those since the 
compiler release. Under the covers, though, methods like File.read() 
allocate a byte[], but return it as a void[] to indicate the lack of 
known type. If I understand correctly, this should address your concern?

Revision 1378 of Tango works with dmd 1.0.  It's tagged for dmd 1.000. 
I haven't tried later revisions.  DWT doesn't work with dmd 1.004, so 
I'm holding off on upgrading.  I expect other people are in the same 
situation.  This will probably change, since the cause seems to be a bug 
in dmd 1.004, related to missing or wrong TypeInfo instances.

I have sc.ini.phobos and sc.ini.tango, and just replace sc.ini with the 
relevant one when I want to switch libs.  If you follow the installation 
instructions on the web site, switching between phobos and tango is 
really that easy.  sc.ini.phobos is the default one, sc.ini.tango is 
edited following the installation instructions on this page:

I have my home directory set up to make this easy.  When I get a new D 
compiler, I unzip it under ~/d/d.1.004 (or wherever).  Then I create 
this symbolic link:

/home/me/d/current -> /home/me/d/d.1.004

Make the binaries executable, fix dmd.conf, and its ready to go.

The following links never change, they redirect everything through 
"current":

/etc/dmd.conf -> /home/me/d/current/dmd/bin/dmd.conf
/usr/lib/libphobos.a -> /home/me/d/current/dmd/lib/libphobos.a
/home/me/bin/dmd -> /home/me/d/current/dmd/bin/dmd
/home/me/bin/rdmd -> /home/me/d/current/dmd/bin/rdmd
/home/me/bin/obj2asm -> /home/me/d/current/dmd/bin/obj2asm
/home/me/bin/dumpobj -> /home/me/d/current/dmd/bin/dumpobj

I can change the "current" symlink to get a particular version of D.

I imagine in Windows you could use rename instead of symbolic links to 
achieve almost the same effect.  With a little more tweaking I could 
switch D versions with an evironment variable.

Walter and the Tango guys:

Cool, both! Congrats!!!!



Wish I'd been there, but lately I've been (luckily only) almost 
electrocuted to death just 3 (three) times simply the last week!

(One of them: 500V DC, 125A. I happened to poke the wrong thing in the 
connection box with my multimeter. Result: a bang that locked my ears, a 
spark that scared the audience, a jolt that threw me back two steps 
without "moving a limb", and a darkness that impressed the guys at the 
other shops in the block.) There's a rumor we're doing something 
"heavy". Not likely we'll clip that one anymore. Oh, and my multimeter 
minus side probe is 1/4" shorter now.

We're in Europe, so the green-yellow striped one is the shield ground 
wire. My associate fastens all three wires while he's talking gossip and 
the weather and NOT looking at what he's doing. He's like the film star 
in the car scene, driving and explaining the plot to the female co-star: 
never even glimpsing the road.

There were 18 plugs he had to wire, and (only after some near-misses of 
life) it turned out he'd miswired more than half of them. Honestly, I'd 
want to "teach" him with a shotgun. :-( !!!!! I've got three minor kids, 
for chrissake!

I'm now doing software for our second Extruder Unit, which is very 
different from the first one. For one thing, the watch points went from 
6 to 10, and then we got 5 pressure points to monitor too. And it's been 
shown to me that a thermostat-like temperature control simply is not 
adequate anymore. We need some kind of adaptive or pre-emptive, or 
learning, temperature "intelligence" with this new machine. (Anybody 
have any pointers, hints or ideas?) And looks like it'd have to "learn" 
from the motor rpm+amperes+voltage + temperatures+pressures + 
first-and-second-derivatives-of-them, and Bob knows what -- to become 
prescient, or at the very least, "aware".

(My associate would not exactly understand if any of you guys would 
suggest I'd tell him he's demanding more than Cyberdyne Systems 
contributed to Skynet.)

Tango is a D library that provides a runtime for the D programming language,
plus many additional library features for the D programmer. Further growth
and sharpening of quality is expected for coming releases.

A feature list can be found on

http://www.dsource.org/projects/tango/wiki/Features

Extensive work has been put into documenting the basic features, and in
trying to make usage and installation easy for as many as possible.
Platform support will be provided with the help of the users. Win32, Posix
x86 and PPC have currently received most testing.

Tango is not yet fully polished, but the last few weeks have seen efforts to
solve toolchain problems, cleaning operations, documentation production, an
improved website and more. Hopefully you will find it a useful addition to
the D world, and feedback will gladly be accepted.

The Tango homepage can be found at

http://www.dsource.org/projects/tango

Downloads:
http://www.dsource.org/projects/tango/wiki/Download - Note that only the
source distributions have been updated. If the main download site don't
provide you with the downloads, try the mirror or try again later.

See http://www.dsource.org/projects/tango/wiki/TopicInstallTango for more
detailed installation instructions for your system.

 I got this message.


Seems to have worked, great :)


 
 Then I tried to compile example/**/*.d, but got errors.
 What's wrong?

Others have been encountering this bug, too, today.. don't know what's 
wrong, though. Is the file tango/core/Exception.di existent?

 I failed to issue install-dmd.sh on my Debian GNU/Linux box.


 
 What exactly do you mean? Does the script fail for you?


 
 Yes. I got a syntax error.
 But after I applied the patch, installation was successful.
 
 ./install-dmd.sh: line 302: syntax error near unexpected token `fi'
 ./install-dmd.sh: line 302: `   fi'

The fix is now in trunk and the 0_95_beta1 branch.
