But it'll make tango depending on phobos which is something that not all people seem to like.

Great news. Makes me wanna do D again after I gave it up mainly because the lack of Tango for D2 and the obvious death of D1 years ago. I don't see the announcement in the tango forums. I'm wandering if the original tango developers have any plans in using D2 and developing tango for D2? Also what are your plans for maintaining the port? Does it seem it will have long happy future or it is more of a hobby project?

All the user modules are now ported (save for tango.math.BigInt, which right now is aliased to std.bigint... this might change in the future). All unittests pass on Linux (using LDC2) and most do on Windows. Additionally, again kudos to Igor, it compiles with -property and -w flags for all of you style purists. Additionally, most of the examples have been also ported.

Don, what about cases when you don't need Phobos at all and you would to stick to Tango+Druntime only?

tango.math.internal.* are mostly constness changes (and coding style change :D)
but tango.math.BigInt and std.bigint seems to be a bit different (more features in Phobos version?)

I cannot speak for SiegeLord, but since the project is on github, anyone can fork it and continue the maintenance. As long as there is someone who wants it to be maintained, it probably will be.

To add to what Timon Gehr said, I plan on using it and thus maintaining it as much as possible. I keep it synched up with the D1 original, so as long as the Tango developers keep improving the original, I'll keep the port updated. I also welcome new features as long as they are in the spirit of Tango, and don't break backwards compatibility too much (after all, a big use case of Tango is for porting).

I haven't talked to the developers about making this an "official" port or anything like that. I plan to in the future.

It should be fixed now. Make sure to compile the example and the library with the -g flag.

That's OK. It has no dependencies on anything else in Phobos.
(OK, recently there is a toString() thing, which needs to be sorted out in general for Phobos/Tango compatibility).

I wrote both of them. The tango one is just a really old version, with many more bugs.

Same here!

This is the number one thing I waited for to be ported to D2. I never considered moving to D2 without Tango. Big thanks to SiegeLord and all the other contributors.

Just one example why I like Tango:

hello_tango.d:
module hello_tango;
// dmd 2.057 + SiegeLord-Tango-D2-4c9566e 2012-01-24
import tango.io.Stdout;

int main(string[] args)
{
   foreach(i, arg; args)
   {
       Stdout.formatln("  arg {,3}: '{}'", i, arg);
   }
   return 0;
}

rdmd --build-only -release -O hello_tango.d

hello_tango a b ä ö
 arg   0: 'hello_tango'
 arg   1: 'a'
 arg   2: 'b'
 arg   3: 'ä'
 arg   4: 'ö'


hello_phobos.d:
module hello_phobos;

// dmd 2.057
import std.stdio;

int main(string[] args)
{
   foreach(i, arg; args)
   {
       stdout.writefln("  arg %3d: '%s'", i, arg);
   }
   return 0;
}

rdmd --build-only -release -O hello_phobos.d

hello_phobos a b ä ö
 arg   0: 'hello_phobos'
 arg   1: 'a'
 arg   2: 'b'
 arg   3: '+ñ'
 arg   4: '+Â'


E:\source\D\d2>dir he*
09.02.2012  15:18               204 hello_phobos.d
09.02.2012  15:18           992.284 hello_phobos.exe
09.02.2012  15:18               250 hello_tango.d
09.02.2012  15:18           180.764 hello_tango.exe

The hello_tango.exe is much smaller and it even works with strange german umlauts :-)

BTW:
Tango doesn't build (bob) with dmd 2.058 beta because of:
...
dmd -c -I. -release -oftango-net-device-Berkeley-release.obj ./tango/net/device/Berkeley.d

For me it is the other way round: I never considered trying Tango until it was ported to D2. =)

fixed:

import std.stdio;

void main(string[] args){
   foreach(i, arg; args){
       writefln("  arg %3d: '%s'", i, arg);
   }
}

Works for me with Phobos perfectly fine. What platform are you on? (probably Windows?)

Harmless 'bug' exposed by bugfix in compiler. Should be a trivial. It would cease to be an issue if this enhancement was implemented in the compiler:
