FREE SOFTWARE FOR WEBSERVICES AND FOR C# PROGRAMMING

As of December 2012, the DotGNU project has been decommissioned, until and
unless a substantial new volunteer effort arises. The exception is the libjit
component, which is now a separate libjit package.

The DotGNU project aims to be for webservices and for C# programs what GNU/Linux
is rapidly becoming for desktop and server applications: the industry leader and
provider of Free Software solutions.

DotGNU currently consists of three main development projects (further components
will be added over time):

 * DotGNU Portable.NET, an implementation of the Common Language Infrastructure
   (CLI), more commonly known as ".NET", includes everything that you need to
   compile and run C# and C applications that use the base class libraries, XML,
   and Systems.Windows.Forms. Currently supported CPUs: x86, ppc, arm, parisc,
   s390, ia64, alpha, mips, sparc. Supported operating systems: GNU/Linux (on
   PCs, Sparc, iPAQ, Sharp Zaurus, PlayStation 2, Xbox,...), *BSD,
   Cygwin/Mingw32, Mac OS X, Solaris, AIX. [Intro] [Download] [Install]
 * phpGroupWare, a multi-user web-based GroupWare suite, which also serves to
   provide a good collection of webservice components, all of which can be
   accessed through XML-RPC so that you can easily integrate them into
   webservice applications of your own.
 * The DGEE webservice server is also moving forward nicely. [Intro] [Download]
   [Install]



Major motivations for being involved in DotGNU include:

 * A desire to prevent Microsoft from achieving their stated goal "that the era
   of 'open computing,' the free exchange of digital information that has
   defined the personal computer industry, is ending". Read the quotation in
   context and learn how the Free Software movement works to prevent this
   disaster. The contribution of the DotGNU project might turn out to be
   important.
 * A technical interest in webservices, bytecode systems, and compiler
   construction.
 * A business strategy of using DotGNU, and contributing to DotGNU. DotGNU is
   part of GNU and thereby protected from coming under the control of any single
   company.




NEWS

JUNE 06-06-2009: DEVELOPMENT VERSION CONTROL SWITCHED FROM CVS TO GIT !

The active development takes place now in a GIT repository on savannah. The CVS
repository will be available for read only access for some time but no further
updates will be committed there. For information on how to obtain the GIT
repository have a look at the GIT info.


DECEMBER 12-10-2008: LIBJIT 0.1.2 RELEASED !

The changes are the switch from GPL to LGPL 2.1 licence, native support of
x86-64/AMD64, a fixed libjit interpreter and various other improvements and
bugfixes. You can get the source tarball from savannah's download area.


APRIL 04-15-2008: LIBJIT RUNS WINDOWS.FORMS APPLICATIONS NATIVE ON X86-64 !

The big brother x86-64 is joining the JIT x86 family. The current CVS HEAD of
libjit, along with the corresponding pnet, can run GUI Windows.Forms programs in
pure JIT mode on x86-64.


MARCH 03-20-2007: DOTGNU PORTABLE.NET 0.8.0 RELEASED !

After a year of work, the Portable.NET x86 JIT is finally ready to leave the
confines of CVS into a stable release. The new release includes the new libjit
based x86 JIT with all the bells and whistles as well as all the bug fixes which
have gone into various parts of the system. This release is also the first to be
gift-wrapped by klausT & co, rather than our regular release master rhysw. You
can get the source tarballs from savannah's download area. Give it a whirl, it
should be faster, better and more stable than ever before.


FEB 02-23-2007: DOTGNU IN "REAL LIFE"(TM)

Despite what this scarcely maintained webpage might suggest, interesting things
are afoot in dotgnu developer land. We've finally managed to catch a glimpse of
DotGNU in action from the Trumpf labs. Take a closer look at their laser
appliance control panel, which is a Windows.Forms application which uses a
touch-screen interface. The appliance and dotgnu was recently featured in the
Elektronik magazine issue 03/2007 (in German).


AUG 08-21-2006: LIBJIT ON ALPHA

As part of the Google Summer of Code project, tcort has been hacking away at the
libjit port to alpha. As the SoC was ending yesterday, tcort showed the basic
JIT samples working on alpha, including on-demand compilation and execution of
functions. There is a lot more work left in Alpha land and tcort has said that
he plans to continue working on it. Take a look at his blog post and the
screenshot. If you're interested in helping, take a look at his Alpha porting
guide first.


AUG 08-19-2006: LIBJT RUNS WINDOWS.FORMS APPLICATIONS

Over the last few months, libjit has made progress in leaps and bounds. The
current CVS HEAD of libjit, along with the corresponding pnet, can run GUI
Windows.Forms programs in a pure JIT mode on x86. Actually, it has been
functional for a while now. We apologize for the delay in announcing this, but
we are all too busy hacking :)


MAY 01-05-2006: GOOGLE SUMMER OF CODE 2006

DotGNU is taking part in the Google Summer of Code 2006 as a part of the GNU
Operating System. If you are a student and are interested in working on DotGNU
(or another part of GNU) see the list of GNU ideas. The DotGNU related items are
mainly about implementing C# 2.0 features in the compiler, enhancing
System.Windows.Forms and improving libjit. DotGNU related Summer of Code
projects can be found on this list.


MARCH 04-03-2006: DOTGNU WEBSITE REDESIGN

We are currently looking at redesigning dotgnu.org and building a new look and
feel. The old template system is also going to be replaced with an XSLT based
one. If you are interested in helping, please join up on the #dotgnu IRC channel
or mail the developers mailing list, we are very interested in general proposals
and mockups.


FEBRUARY 11-02-2006: LINUX.CONF.AU 2006

Some DotGNU developers met at this year's Linux.conf.au in Dunedin, NZ to
discuss plans for 2006. Some DotGNU people can be seen on this photo. Apart from
a nice dessert, there was also quite some discussion about Portable.NET's
future. The conclusion was to go ahead and give Portable.NET a big boost in 2006
as there is a lot of exciting technology in Portable.NET to play around with.


JANUARY 15-01-2006: DOTGNU PORTABLE.NET 0.7.4 AND LIBJIT 0.0.6 RELEASED!

New versions of Portable.NET and libjit are available. Far too many new features
and bug fixes to list them here, see the announcement which includes a full list
of new features and bug fixes. You can get it from the download page.


DECEMBER 03-12-2005: PORTABLE.NET AND LIBJIT PROGRESS

Work on libjit (A JIT designed to be independent of any particular virtual
machine bytecode format or language) has resumed again and we are gearing
towards using it in Portable.NET soon. Recently, there have also been donations
which will be distributed amongst developers who contribute code to get libjit
finished and hook it into Portable.NET's runtime engine.

On Portable.NET related news, there have been many changes since the last
release, probably the most notable one is the development of libCrayons, the new
System.Drawing backend. With a bit of luck, developers can even get one of the
Windows.Forms related bounties for their code contribution.

If you are interested in any of the recent libjit or Portable.NET developments
you should subscribe to the mailing lists or talk to us on IRC.


AUGUST 17-08-2005: DOTGNU PORTABLE.NET 0.7.2 RELEASED!

Changes since the last release and download links can be found in the
announcement.


JULY 31-07-2005: THIRD REVISION OF C# AND CLI SPECIFICATIONS

The third edition of the ECMA C# Language Specification and Common Language
Infrastructure (CLI) have been approved recently.


JUNE 11-06-2005: DOTGNU PORTABLE.NET 0.7.0 RELEASED!

We have reached yet another milestone: Portable.NET 0.7.0. There is an unroller
for PPC, runtime optimizations and fixes all over the place, many
System.Windows.Forms, System.Drawing and Xsharp fixes plus XML and networking
enhancements! See the announcement for a more detailed list of changes and get
it from the download page.


JANUARY 16-01-2005: DOTGNU PORTABLE.NET 0.6.12 RELEASED!

Portable.NET 0.6.12 and TreeCC 0.3.6 have been released today.

For a list of changes and bug fixes read the announcement or visit the download
page where you can also find binary packages for numerous platforms.


DECEMBER 05-12-2004: VIDEO CLIP OF DOTGNU RUNNING ON ENCORE SIMPUTER

DotGNU Portable.NET has been ported to the Encore Simputer, a handheld computer
based on on Intel's StrongARM CPU (a RISC microprocessor designed for embedded
applications), within 72 hours after the release of Encore's port of the
GNU/Linux development tools for this platform at the "Linux Bangalore/2004"
conference. Conference organiser Atul Chitnis said, ''I threw the challenge as a
joke, the bet being a cup of coffee. Gopal borrowed a PC at the conference, and
finally an Encore Simputer, and came to me on the third day, saying that I now
owed him a cup of coffee. It took a few seconds before the enormity of that
statement hit me.'' Here's a video clip.


OCTOBER 30-10-2004: DOTGNU PORTABLE.NET 0.6.10 RELEASED!

Version 0.6.10 of pnet, pnetlib, pnetC, and ml-pnet and version 0.3.4 of treecc
have been released. The full release announcement is here.


SEPTEMBER 25-9-2004: GETDOTGNU.COM COMMUNITY WEB PORTAL LAUNCHED

GetDotGNU.com is a new web portal dedicated to DotGNU and its development
projects. The site features news articles and editorials, forums, downloads,
screenshots, and many other great features. It is time to Get DotGNU! now.


AUGUST 7-8-2004: RELEASE OF PNET, PNETLIB, PNETC, ML-PNET, TREECC, AND LIBJIT

Version 0.6.8 of pnet, pnetlib, pnetC, and ml-pnet, version 0.3.2 of treecc, and
version 0.0.4 of libjit have been released. There are lots and lots of bug fixes
and new features. The full announcement with NEWS entries and signed MD5
checksums is here.


JULY 7-7-2004: PHPGW 0.9.16.002 SECURITY FIX RELEASE

All phpGroupWare versions earlier than 0.9.16.002 set header admin and setup
passwords as plain text cookies. Now the bugfix security release 0.9.16.002 is
out which fixes this security problem.


MAY 29-5-2004: DOTGNU PORTABLE.NET 0.6.6 RELEASED!

Even though Rhys was on "sabbatical" away from Portable.NET during this release
cycle (he has been working on libjit), major progress has been made in many
areas, including in particular threading, Winforms, System.Xml, ml-pnet, DCOP
and serialization.

The full release announcement is here.

Here are some screenshots: Portable Studio IDE, MyXaml, Photo Tool (wx.NET), KDE
DCOP Support, MDI and FileDialogs, Gtk-Sharp, Svg Rendering, XHTML Rendering .


MAY 13-5-2004: LIBJIT-0.0.2 HAS BEEN RELEASED!

Rhys has packaged up the current state of the libjit tree into a libjit 0.0.2
release.

Libjit is now at the state where primary testing and bug fixing can begin. We
initially need test cases that cover all of the functions in "jit-insn.h".

The easiest way to write a test case is to write a small program in the "Dynamic
Pascal" language that exercises the feature in question. Then place it into the
"libjit/tests" directory. The "libjit/tests/README" file contains more
information on how to do this. A couple of test cases are already provided that
demonstrate the concept.


APRIL 27-4-2004: LIBJIT-0.0.0F HAS BEEN RELEASED!

The libjit library implements Just-In-Time compilation functionality. Unlike
other JIT's, this one is designed to be independent of any particular virtual
machine bytecode format or language. The hope is that Free Software projects can
get a leg-up on proprietary VM vendors by using this library rather than
spending large amounts of time writing their own JIT from scratch.

This JIT is also designed to be portable to multiple architectures. If you run
libjit on a machine for which a native code generator is not yet available, then
libjit will fall back to interpreting the code. This way, you don't need to
write your own interpreter for your bytecode format if you don't want to.

libjit is independent of pnet (that's one of the main points!) but we'll
eventually modify pnet to use it for JIT'ing.

In the newly released version 0.0.0f, tutorials 1 to 4 now work correctly using
the interpreted back end, which should allow people to experiment with real
examples now. The x86 and ARM back-ends should follow in the next few days.

A mailing list for libjit-specific discussions has been set up.


MARCH 13-3-2004: DOTGNU PORTABLE.NET 0.6.4 RELEASED

Portable.NET 0.6.4 and Treecc 0.3.0 have been released. The big change this
cycle is the C compiler, which has now reached the point of being useful. We now
need lots of volunteers to help flesh out the C library, pnetC, to include all
of the usual libc features. There have also been a lot of bug fixes and
performance improvements in System.Windows.Forms, thanks to Neil Cawse. And
Richard Baumann has completely rewritten the System.Xml parser, fixing many
long-standing issues with the XML library.


MARCH 6-3-2004: C COMPILER: SIGNIFICANT PROGRESS AND CALL FOR VOLUNTEERS

The new C compiler type system has been checked in. Type layout is now totally
dynamic; the IL binary will automatically adapt itself to the runtime engine it
is running on. This means that DotGNU is bringing true "write once, run
anywhere" functionality to C, running on top of standard CLR implementations.
Unlike Microsoft's C compiler, whose output will only run on i386-based Windows
systems, ours will run portable ANSI C code on any platform that has a CLR, be
it 32-bit or 64-bit, little-endian or big.

Simple examples of C programs can be compiled to IL now, and volunteers are
needed to work on the standard C library so that more programs and libraries can
be compiled. Our eventual goal is to bring a large body of Free Software
libraries and programs to the CLI environment, vastly increasing the range of
functionality beyond the small number of libraries currently defined for C#.


FEBRUARY 28-2-2004: .NET DEVELOPER'S JOURNAL READERS' CHOICE AWARDS 2003

We were mentioned in the ".NET Developer's Journal Readers' Choice Awards 2003",
achieving third runner up in the "Best .NET Build Tools/Installers" category and
second runner up in the "Best .NET CLI" category. The full details are at the
following URL:

FEBRUARY 27-2-2004: INTERVIEW WITH NB ON GNU-FRIENDS.ORG

Gnu-friends has an interview about the history of DotGNU and nb's views on Free
Software philosophy: http://gnu-friends.org/story/2004/2/27/15415/3365


FEBRUARY 11-2-2004: "DARWINPORTS" PACKAGES OF PORTABLE.NET 0.6.2 FOR MAC OS X

Thanks to the efforts of olegb, "DarwinPorts" packages of DotGNU Portable.NET
0.6.2, including System.Windows.Forms, are now available. To install, use "port
install pnet; port install pnetlib; port install ml-pnet"


JANUARY 3-1-2004: PORTABLE.NET 0.6.2 RELEASED

Version 0.6.2 of DotGNU Portable.NET has been released with many enhancements
particularly in the area of System.Windows.Forms, with improvements to most
controls, fonts, MDI, tree views, and file dialogs. Please use the Southern
Storm site for now for downloading it, as we are currently unable to update
ftp.gnu.org


JANUARY 11-1-2004: PORTABLE.NET ON PLAYSTATION 2

Thanks to the efforts of Adam Ballai and Lance Gilbert DotGNU Portable.Net is
now running on Sony Playstation 2 (which has a little endian "R5900 V3.1" MIPS
cpu.)


JANUARY 12-1-2004: DOTGNU AT LCA2004

Four DotGNU'ers have made it to LCA2004 in Adelaide, Australia. A group photo is
here. From the left, we have Andrew Mitchell (ajmitch), Rhys Weatherley (rhysw),
Chris Smith (cds), and Dave Hall (skwashd, who wishes to remain anonymous for
reasons unknown).


JANUARY 13-1-2004: WEBSITE UPDATE

All official GNU websites (which are on www.gnu.org or tightly synchronized with
www.gnu.org, where in the example of DotGNU, our website is at
http://www.gnu.org/projects/dotgnu/) were in hiatus between mid-November 2003
and January 2004 due to a security breach at an important server of the Free
Software Foundation, and the resulting need to set up a much more secure system.
The new system is available now, although it seems to have a bug which prevents
the www.gnu.org version of the DotGNU website from being updated. Since the
DotGNU project has important news to share, and I don't have much hope of this
project-specific bug being treated with priority (it may have to do with DotGNU
being under /projects on www.gnu.org and not under /software like almost
everything else), I'm now updating dotgnu.org without waiting for the savannah
webcvs bug to be fixed.


NOVEMBER 6-11-2003: DOTGNU SNAKE!

Support for the upcoming "Whidbey" System.Console routines has been added to
Portable.NET, and there is a simple "Snake" game that demonstrates how to use
it. A screenshot is here


NOVEMBER 4-11-2003: DOTGNU 0.1 RELEASE ANNOUNCEMENT

The release announcement for the DotGNU 0.1 CD-ROM release has been posted.


NOVEMBER 2-11-2003: EMBEDDING X APPLICATIONS IN XSHARP

It is now possible to embed any X application as a child widget within an Xsharp
application. The pnetlib CVS tree includes "XClockEmbed.cs" as an example of
doing this for "xclock", and this screenshot shows both "gedit" (a GNOME app)
and "kcalc" (a KDE app) running as two children of the same Xsharp main window.
This is important because the next version of WinForms will have a HTML web
browser control widget, and we will want to embed an existing third-part Free
Software web browser, and not write a web browser from scratch in C#.
