digitalmars.D.announce - Tango 0.97 RC1 released

reply Lars Ivar Igesund <larsivar igesund.net> writes:
Dear D community

This is the first release candidate release of Tango towards 1.0. This is
mostly a bugfix release, plus some news in the packaging department. The
most important changes are:

 * bundling of DMD
 * fixes for 64 bit use
 * fixes for Mac OSX use
 * daily snapshots
 * executable installers also on Linux

For a complete list, see
http://www.dsource.org/projects/tango/wiki/0_97_Changelog. There are still
a few rough edges, so we welcome all feedback and testing. Mac OSX
functionality has improved a lot, but we are still seing issues, mostly due
to differences between GDC and DMD in addition to a couple of show
stoppning bugs in the compiler.

DigitalMars has graciously given the Tango team permission to redistribute
DMD. This release sees the first packages of these bundles. Executable
installers are now also available on Linux, for both DMD and GDC. Please
report back on your experiences. Some downloads (GDC mainly) may take up to
a day before they are up.

Great stuff; I'll certainly be checking this out when I have some time!

One thing I'm very curious about, though: has anything changed to make 
Tango and Phobos play nicely together (e.g. removal of the hard-coded 
dependency on libphobos in dmd)? (I've been occupied with uni and work 
for the last couple of months so I wouldn't have noticed if it had!)

I ask this because I'm really eager to play around with Yage and some 
other projects that use Phobos, but my every-day use of D is with Tango.

I've created a compatibility layer, tangobos. It's mainly intended for 
porting (since porting incrementally is infinitely easier than porting 
in one blow), but I think it could also be useful for using Phobos 
libraries which you don't control in a Tango app, since it would be a 
bit silly to maintain a fork of an active app just because it doesn't 
use the right core library.

It's a bit controversial though :P

Tangobos doesn't have a home page yet, but stay tuned.

I think Tangobos is an excellent idea. Tango appears to be a powerful 
library, but I'm already used to Phobos. So it'd be nice to still be 
able to fall back on some Phobos functions as I try to learn more about 
Tango.

For example, I was trying to write a simple example using Tango, and I 
quickly discovered that I was having a hard time figuring out how to do 
anything. It's not than I think that Tango is inferior in any way to 
Phobos, it's just that I've become accustomed to the "Phobos way". If I 
want to replace one set of characters with another set of characters, I 
knew that all I have to do is use the replace function in std.string. 
When I tried to do a similar operation with Tango, I felt and 
embarrassed at my ineptitude (I suspect it's a simple matter of using a 
String object and using the right member function, but I couldn't get 
anything to work).

I had similar problems when I was first trying to learn how Phobos works 
(along with the additional problems of being new to D and D being such a 
young language). For some reason, I thought those days were behind me, 
but I forgot that every library is going to have it's own style. And 
learning the style can take some time and effort.



 Tangobos doesn't have a home page yet, but stay tuned.


I'll be waiting.

No reason to feel embarrassed, Tango _is_ different from Phobos. Tango
having a String class don't mean that there aren't any free functions to do
string handling though. Maybe

can lead you in the right direction?

 Dear D community
 
 This is the first release candidate release of Tango towards 1.0. This is
 mostly a bugfix release, plus some news in the packaging department. The
 most important changes are:
 
  * bundling of DMD
  * fixes for 64 bit use
  * fixes for Mac OSX use
  * daily snapshots
  * executable installers also on Linux
 


Great that DMD can be redistributed with Tango. It looks like soon 
problem of original, messy bundle for DMD will be resolved :-)

I just would like to propose to make few enhancement to current 
directory structure of installation:

* First - do not assume that people will use only Tango, but no Phobos 
at all.

Directory structure should allow to have installed Tango *AND* Phobos 
simultaneously. I propose sth. like this:

|-bin
|-doc         (maybe like on linux: share/doc/tango ??)
|  |-tango
|  |-phobos
|  |-<other libraries>
|
|-example
|  |-tango
|  |-phobos
|  |-<other libraries>
|
|-import
|  |-tango
|  |-phobos
|  |-<other libraries>
|
|-lib
|  |-tango
|  |   |
|  |  <libs>
|  |
|  |-phobos
|  |   |
|  |  <libs>
|  |
|  <common libs>
|
README.txt


I know that Tango is replacement for Phobos, so you may think that it is 
  unnecessary work to provide additional support for it. But I think it 
will make Tango more popular allowing people to use easily both 
libraries as necessary. Probably you could even consider to include 
sources for Phobos in bundle (if Walter allows it).

* Second - dsss and rebuild should be bundled with Tango. Rdmd should be 
merged to rebuild and removed from bundle then (I've put ticket for this 
enhancement for rebuild).

* Third - there should be dmdc script (second one from Andrei, which 
generates dmd.sc/dmd.conf for Tango or Phobos). This script could even 
scan import directory for paths to other libraries and generate proper 
script.

Thanks for addressing issues with uncomfortable installation of DMD and 
libraries for D!

Such script is not a good solution when it is possible to run several  
copies of dmd at one time (from different consoles for example) and one of  
copy use Phobos and another Tango.

When you need customized solution there is no way to find one which will 
  satisfy all people. In case you have described I would say that it is 
rather unusual that someone parallely use Phobos and Tango (just my bet).

Script can be easy customized to generate  dmd.sc / dmd.conf to current 
working directory rather than to bin directory. Then you can use Tango 
AND Phobos parallely.

I don't think we do, but I am sure there's still room for improvement.
Having imports for both should work out fine, having two
libphobos.a/phobos.lib around is worse (without changing configurations, or
actually having two installs).

A better solution for the docs is definately something we want.

We will certainly look at the above proposal for directory structure.


 
 I know that Tango is replacement for Phobos, so you may think that it is
   unnecessary work to provide additional support for it. But I think it
 will make Tango more popular allowing people to use easily both
 libraries as necessary. Probably you could even consider to include
 sources for Phobos in bundle (if Walter allows it).


I am pretty sure redistribution of the source is no problem, but we do
consider it a problem to (officially) distribute something that we don't
mantain ourselves. Gregor's tangobos effort may very well be the easier
solution in most cases where one is in need of using both, and I expect
that one to be available via DSSS.


 
 * Second - dsss and rebuild should be bundled with Tango. Rdmd should be
 merged to rebuild and removed from bundle then (I've put ticket for this
 enhancement for rebuild).


We will most likely make such a bundle (there already is for GDC), but we
will still need packages not depending on it. We may also label it
unofficial, given that DSSS/Rebuild is no Tango project per se.


 
 * Third - there should be dmdc script (second one from Andrei, which
 generates dmd.sc/dmd.conf for Tango or Phobos). This script could even
 scan import directory for paths to other libraries and generate proper
 script.


Feel free to approach is with further suggestions on this.


 
 Thanks for addressing issues with uncomfortable installation of DMD and
 libraries for D!


We are trying - but as of yet we do not want to provide official
distributions for tools/libraries not part of Tango itself (the compilers
being notable exceptions).

We may set up a page for more unoffical distributions however, if they can
be easily mantained and updated. Typical problems with such setups though,
are related to tool and library updates outside the Tango release cycle,
which is why tools such as DSSS probably will become much more useful in
the long run.

Further we would like to provide improved support for the different package
distribution systems on Linux and other platforms, if someone would like to
help out with creating such packaging.

I have RPMs pretty much ready to go for Tango, just polishing on the 
interaction between the -phobos-devel and -tango-devel packages...

As it stands now, you can install either of them - not both at once
(since they both supply an object.d file and a libgphobos.a library)

Will try to fix the build system so that it can build some packages.
(currently just installed on Fedora Core Development, so not for FC5)

The easiest way of installing Tango on Mac OS X is installing a fresh 
copy of GDC (and Rebuild) in a separate directory, like /opt/gdc or so.
Then set the PATH to this alternative prefix (PATH=/opt/gdc/bin:$PATH),
and build/install Tango there and finally use Rebuild to build programs.

So to use the regular library you would call /usr/bin/gdc (e.g. gdcmac),
and to use the alternative library it would call upon /opt/gdc/bin/gdc.

Thanks to Anders Bergh, we now have a Arch Linux repository set up for use
with Pacman. It lets you install, and later upgrade DMD and Tango via
Pacman.
