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)

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.

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.

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?

Thanks. That looks like exactly what I needed.

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.

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.
