2. Why is the old CVS chosen instead of the newer SVN?

GEGL is more than 6 years old. Subversion simply didn't exist at that time. GNOME project has no SVN. Believe me, neither chosen programming language, nor type of versioning system affect (absense of) development of GEGL.

Oh, 6 years old. Got it.

6 years... I wonder if changing to a higher level language like C++ or better yet C# (mono has good enough support now) would speed up the development. I think it would.

What do you guys think?

The reason for using C is that it is much easier (possible) to make bindings for other languages, C, C#, C++, Python, Ruby etc.

The biggest obstacle to GEGL development as I see it, is that in its current state it doesn't do any actual image processing. Personally I find it difficult to improve on a non-working system.

I am aiming to improve on this by next weekend when I am going to do a presentation about GEGL at LGM [1] in a bout a week. My current efforts of replacing all the image processing of horizon [2] gives reason for optimism [3], the code that is in CVS is doing what it is intended to do and my overview of what needs to be done is improving.

Mono? Are you kidding? You want pure C application talking to a C# backend? You've just made my day :)

Well, of course there is a C++ VIGRA that is somewhat similar to GEGL and is already used in some projects like Scribus and Hugin, but those are written in C++, and general idea would be using same language for "backend" (or, rather, libraries) and "frontend", though an alliance of C libs and C++ frontend is known to work in gazillion cases. But not the other way round.

FYI, the transistion of the GNOME CVS to GNOME SVN is planned for the next weekend. Yes, this is the LGM weekend, and yes, this means that we might not have easy access to the current source of GEGL, GIMP or other GNOME software. See http://live.gnome.org/Subversion for more information.

I have moved 2 or 3 projects from CVS to SVN : the python script which does that works pretty well!

I have no doubt that it will work, but GNOME CVS contains more than 3 projects. Luckily, we (GIMP) are scheduled to be moved first: http://svn.gnome.org/~rossg/migrate-me.list - but gegl is still in the default alphabetic order.

And even if the migration is done on the server level, it has to be done on the client as well. Installing SVN, migrating the source trees, ...
