Indigo is a project to provide a platform-independent non-GUI library that accomplishes some of the tasks of the Qt library for C++. Everything is designed to behave as equal to its Qt equivalent as possible, but also to take advantage of D specialties. Everything should be fast and simple. Currently it includes almost all Qt containers, a clean signals&slots implementation, I/O with IODevice, File and DataStream, and internationalisation basics with fast UTF conversion and message translation (including 2 helper programs imupdate and imrelease).

The new message translation module is very easy to use, and the helper program imupdate produces TS files like lupdate from Qt. Use linguist or KBabel to translate, and run imrelease (equivalent to lrelease) afterwards. Message translation is heavily optimized, and imupdate has a sophisticated algorithm to find similar older translations for new/changed strings. I would be happy to receive comments on the API and the programs.

Ah, and i forgot: The whole library is now LGPL-licensed. Thanks to Stewart for pointing this out to me. License is included as well, and the zip file now also contains the HTML docs.

Are there any screenshots available? I'm very interested in a matter of "look & feel" of indigo. Does it use (will use?) pure XServer / WindowsAPI or some frontend (gtk or smth).

Sorry. Now I see _non_ -GUI word. Late here - I need a sleep ... dreaming about the library with Qt frontend. :)

I can compile the modules into a library using a home-made makefile. However, when I try to use it, the linker complains that the symbol _lstat is undefined.

Is there some undocumented library requirement?  Or has it just not been tested under Windows in a while?

The I/O modules have been tested under Windows as well, but obviously not after adding the lstat() function (needed by File.exists). I have fixed the error, and uploaded a new indigo.tar.gz.

Thanks for the report.

How about LGPL with exception allow static linking?

Like the wxWidgets Licence:

Arrggh this licensing stuff eats more time than programming. :)  Well, of couse you can link the library to your program statically. There is no way beyond it anyways, as all the templates must be instantiated "freshly". I'll add a notice to the license.

Thanks & ciao

Well, i changed my mind. I will leave the license unchanged. There are enough options specified in section 6 of the LGPL that permit binary distributions of works using the library. If someone needs an exception for his commercial application, he can still contact me.

I've now got it installed and running.  Just a few issues drop it short
of perfect.  For example, it's a step behind std.stream in that it only detects EOF after trying to read past the end.  My thought is that an I/O library should be able to detect EOF when it gets there, and that one should also be able to rely on exceptions to catch a premature end of file.

This would be simple to implement for File.  It might take a bit of work for other IODevice types but it would be worth it IMO.

But I believe a TextStream is a feasible addition to this library, with the help of a few more IODevice members to help with UTF detection and the like.  I'll see what I can do....
