digitalmars.D.announce - Tango for D2: All user modules ported

Hello everyone,

Just wanted to put out an announcement with a progress report on porting effort
of Tango. For those that don't know what it is, Tango is a framework library
that used to be/is the de facto standard library of D1.

Through the heroic efforts by Igor Stepanov, the initial porting was completed
ahead of schedule. 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.

I have personally used Tango in few KLoC line D2 project and I find it works
just as well as it did in D1.

This is naturally not the end, in the coming weeks/months you can expect the
following:

-New Makefile based build system
-Documentation creation
-Ironing out of a few const related inelegancies
-Revival of the support for MacOSX and FreeBSD
-Revival of the GDC
-Shared library creation
-Dance lessons

You can download the latest version of it here:

FAQ

Does it work alongside Phobos/does it use druntime?

Yes and yes.

Why are you doing this?

Because I want to.

Ok, I see. Then we would have four different build methods:

* bob.d
* bob.rb
* makefiles
* shell script (don't know if this works)

Not shell script (I wouldn't know how to get it working, don't know shell well
enough). The Ruby is in a similar situation, but perhaps I can learn enough of
it to fix it (or someone can step up, it probably works now thanks to your
efforts). I know enough Makefile to fix that up too if needed.

Same here for me with shell scripts. I almost hate shell scripts as bad 
as makefiles. You don't have to worry about the Ruby script. I created 
that one, and it already works for at least Mac OS X. Hopefully it 
already works on the other platforms.

The reason I created the Ruby script was the chicken and egg problem. I 
wanted to build the latest version of Tango, they had changed the build 
script to be written in D. There was no pre-compiled binary for Mac OS X 
and the build script used the latest version of Tango.

I think Ruby is a great scripting language and it's installed out of the 
box on Mac OS X.

So, any issues with Ruby script, just let me know.

Any comment that you can make on performance. Is it faster or slower 
than D1 ?

It's hard to say. I write very non-idiomatic D2 code... I don't use the string
type at all, saving on quite a bit of GC use. I would say that if you code just
like you did in D1, but use the const system to enforce some safety then your
code will be just as fast as it was in D1. If you start using immutable and all
the extra allocations that entails... I doubt it'd be nearly as fast.

As this project was written from scratch in D2, I don't have a D1 version to
compare to... Lastly, this was a game, so most of the time consumption comes
from the graphical pipeline... 

As for Tango itself, yes I had to add a few .dups here and there. They are
relatively rare, however, and usually only happen when an error is raised. I'd
be very surprised if under normal usage TangoD2 is significantly slower than
the original Tango.

I would recommend Waf for your build system, but the downside is that it

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

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.

 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.


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


 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;
 }


fixed:

import std.stdio;

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


 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'

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:

But I started using D back in the pre 0.125 days (2004) and I got 
used to using Tango.


 fixed:

 import std.stdio;

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


Just tried again with dmd2.057 and dmd2.058 beta:
    foreach(i, arg; args) {
        writefln("  arg %3d: '%s'", i, arg);
    }

And it's still the same.

Yes, Win XP SP3 32 Bit.

OT:
Just tried the new DMD 2.058 beta:
Whoa! Magicians at work.

I do like this:

hello.d:

module hello;
import std.stdio;
void main(string[] args)
{
    foreach(i, arg; args) {
        writefln("  arg %3d: '%s'", i, arg);
    }
}
rdmd --build-only -release -O hello.d

dmd2.057:
E:\source\D\d2>dir hello.exe
09.02.2012  18:21           992.284 hello.exe

dmd2.058beta:
E:\source\D\d2>dir hello.exe
09.02.2012  18:22           216.604 hello.exe

+1

Will have a look.

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