Great. I will now put a link to that from the main page and put it also
on the blogger. I have fixedup the main page a bit. No more putting it
off.http://introspector.sourceforge.net/
Any ideas as to what should go there?

Can you please a link to the sf log on the web page 
http://sourceforge.net/sflogo.php?group_id=19878

Please Do.
I still am working on the pixbuf, that uses the various
libpng, jpeg and even tiff i guess to render on. 

Don't think I will get any hacking done tonight.

Re: [Introspector-developers] Introspector Status Report 18 Nov. 2002

[James M. D. <mdu...@ya...>]

Stepen,

Thanks for your support. 
I have submitted here to get into savannah :
http://mail.gnu.org/pipermail/savannah-hackers/2002-April/007285.html

and again for the GNUVCG.

The introspector was held up because the sources were not all GPLEd,
I have to resubmit. The GNUVCG is awaiting approval for the name.

You are right, I should push to get this into savannah, alot harder.

Yes!

I have to admit that I have provoked some negativity to begin with, 
it seems that now we have found a happy medium, and with more people
interested in the project, it will be hard to stop now.

But, I still have the mail from RMS asking me to delete the project,
and let me tell you, he has tried this on a number of people.

yes, well I am waiting for the VCG for now,
that is needed and wanted by the fsf, and the gcc developers.

As soon as we get the introspector source in a bit more cleaned up
state, I will resubmit it. First i want to finish this mingw32 port,
and then I will start really hacking at the perl code.


thanks again,

mike

Sorry to pipe in here, but this has been sitting in my head for some 
time. As the FSF has been in some cases hostile to your project, James, 
in my observation at least, it would be an excellent challenge to 
Savannah's intended role in the community to add Introspector to its 
project rolls.

To explain: as I recall, Savannah was originally created in response to 
the "closing" of SF, as well as to answer the need for a free-software 
community counterpart to the OSI-community's SF. GNU, as the host, is of 
course allowed to lay out the ground rules for such a system (GNU in/not 
in project name, GPL-compatible licensing, etc.). However, to allow a 
free community of various projects, it must be willing to accept those 
projects that do not seem to be in line with goals elsewhere in the GNU 
organization; namely, the GCC project. (Though this has changed, no?)

So the offering of the Introspector project proposal to Savannah might 
prove interesting. It might offer Savannah a chance to show whether it 
was for the community, or whether it would be susceptible to the whims 
of GNU leaders. A political test case for Savannah, if you will.

Personally, I feel that they will demonstrate the former. Then again, I 
am usually confident that GNU is doing/will do the right thing.

Dear Fellow Hackers,

This is just a quick note to let you know that the introspector web
filesystem is no longer read only. The ssh is back up and running.

I have uploaded the new ATK (accessiblity toolkit) port to mingw32 and
also the source code to pango.

[Introspector-developers] Introspector Status Report 18 Nov. 2002

[James M. D. <mdu...@ya...>]

Dear Fellow Hackers,

The introspector project is approaching a major milestone in the GUI
area. Mike Garnsey and I have been busy hacking away at the
repackaging/re-porting of GTK+/DIA to Windows. We are using the mingw32
cross compiler under Debian GNU/Linux to create windows binaries.

The new packages are so easy to use, you can compile for windows under
debian with the familiar dpkg-buildpackage command, all the nasty work
is being done in the background.

Just this weekend, we have prepared the libart, Pango, and Atk for
testing. That leaves just the gdkpixbuf and GTK+ before we are done. As
you can imagine, a GUI will be of great value for the system.

Also, the FSF has stated that they are interested in the GNUVCG name,
and are considering adopting the VCG as a GNU project.

As soon as we have dia ported over, VCG will be the next step in
creating on of the most powerful software development tools in the free
software world.

The sourceforge server has been down for a move, and I have been in
contact with the debian-sf (debian sourceforge) project about finding a
new host. The server objectweb. http://debian-sf.objectweb.org/ might
be a possible new home, if not savannah itself.

I have done some review of the gcc interface code, the perl modules.
That needs alot of work, and I promise to tell you more about that real
soon now (tm). Basically we will be beefing up the class model with
more documentation, with links to the original gcc docs, and getting
the java interface up to speed. Via perls Inline::Java we should be
able to interface the perl and java code. By using a SAX parser, we can
be able to write modules directly in java as well.

More to come.

Mike

RE: [Introspector-developers] Deployment Diagram

[Dupont, M. <mic...@mc...>]

ok, Looks good. I think i owe you some explainations.

> Here is my first attempt at a Introspector deployment diagram.  Please
> bear with me because I am just starting to understand Introspector.

The only thing is that we need to revist are the treecc generatorm,and the
threelayers of the intrspector, the meta-level, the compiler level, and the
runtime.

The treecc generation is on the meta-programming level, based on 
the introspector class model that I have shown you. This is dealing with the
types of
tree nodes.

This .tc files fed to the treecc will generate a set of classes for using in
the compiler.
These c bindings that get later linked into the gcc compiler.
That will be used for writing trees back intot the compiler,
otherwise, an XML reader would work as well.

So we have two levels right now :

THe meta-level with the descriptions of the classs,
this is part of the introspector.pl/intrspctr.pl, here the framwork classes
are outputted.

Later the classes are used for reading an XML stream. that is the compiler
level.

so we have :

1. definition of tree classes fed into the introspector
2. introspector creates all types of classes for holding these objects
3. The user installs callbacks into these classes for specializing the
introspector.
4. gcc dumps xml

--- here are the future steps :

5. the c_files/process.pl reads in stream and instanciates objects that were
defined in step 2
the callbacks from step 3 are executed.

6. The user defined code and that could be generated from 5 will be linked
into the final executable program, this would then be called and executed by
the user.

7. Some functions of the itrospector are embedded directly into the gcc, by
the creating of built in functions we can provide access to the trees to the
users of the compiler! This will allow very very interesting programs to be
written.

I hope that I have explained things a bit better.

[Introspector-developers] Deployment Diagram

[Kyle L. <ky...@ar...>]

Here is my first attempt at a Introspector deployment diagram.  Please
bear with me because I am just starting to understand Introspector.

Many of the existing entities should also be given their source code
names for easy reference.

Of course some excerpts for each of the components should follow.

This diagram is only meant for C, I still do not know the necessary
differences for other languages.

Hope you like.

[Introspector-developers] status report november 5 2002

[James M. D. <mdu...@ya...>]

Dear fellow hackers, 

Thank you very much for you help and activity.
This is a long status report, and please read on if you have been one
of the helpers and/or are interested in helping out in the future.

Your help makes a difference, your ideas matter. 
Let me introduce some new and active members of the team,

We have a concrete set of goals for the next months. Get the GCC SSA
branch going, get the DIA port for Win32 going, get it tested,  get the
VCG going afterwards on top of the GTK+ GUI layer.. 

Mike Garnsey is the first active member of the project, he has posted
his LIb Pthread and libxml dlls for mingw32,I am very happy for all his
good help and support. It is important that we find united goals, so
that the motivation for the completion is higher. He is researching,
testing and documenting the mingw32 interface. Ths work he is doing
with me will give us a cross platform GUI for windows and linux, and
even other platforms. He will also be using this in other parts of
projects he is working on.

Mario Luca Bernardi has been hacking away at the GCC interface, 
togeather we have been testing the GCC interface. I am very happy about
all his good help. He is working on his further education and will be
intergrating some of his research into the gcc into this project.

E-Kyle,  Kyle Lahnakoski  has been helping reviewing the documentation
and providing some good and hard questions. He is interested in parsers
and languages. His work on the YAY, yet another yacc brings some
interesting aspects of parser generators and languages into the
project.

David Barker has done some interesting work with creating xml
representations of a commercial c++ compiler (edg IIRC) and has some
possible usages for the gcc. I hope to intergrate his research into the
project. 

Others have expressed interest and ideas in the GCC interface, in the
GUI tools, in the mingw32 port. 

The VCG usage has gotten some interest as well. I have received 3
patches, including the un-uglified one. The meeting with the FSF Europe
president George Greve went positive. I hope to have the name GNUVCG,
or  GnuViz(sualizer) approved soon.

The inline and swig groups have shown interest, the dotGNU have some,
but are apathetic to the cause of the introspector. I will send them
some notes of plans and ask for official oks before continuing. that
will buy us some more time.

I am going to be away until next wednesday,
flying back to the USA/NJ for the long weekend. Family visit, and long
weekend. 

The security devision of my work has said they are monitoring 
my irc and webmail, so I'll will be away from the IRC and mail at work 
for a while, sorry, it was fun.

The next goal for the project is the complete documentation of the
class model and some simple examples for building a compiler interface.
Alot of people have asked if we are still in the design stage,
no we have parts running, some with older versions of the compiler, 
but yes, the project is running, yes you can test parts of it. Yes we
are coding, we are not just in design stage.

It is time for me to buckle down, to start concentrating on things that
have to be done, and to remove the things that don't need to be done.

That means that I will be helping Mike and Mario as much as possible,
because they are the most active in the project and deserve the most
help needed. I will be supporting them in any way possible.

The irc channel #introspector at the irc.openprojects.net has come
along nicely, I am happy that so many of you have tried the connection.

I hope that by the end of novemeber we will have the dia/win32 port
ready for testing and the gcc/ssa branch as well. In fact, I hope to
port the gcc xml dumping to the cross compilier and create our own
package for the the gcc cross compiler. That will allow us to
experiment 
with the introspector on a set of needed packages.

I will also put the inline and cscc interfaces on hold for now,
the projects are not moving as we need them yet, and we need to get
some  
solid experience with releasing stable packages. I am grateful for so
many people subscribing to the mailling list, and hope that more will
step up and help out. It is strange for me who has been working on this
idea for so long to see so many good people help out.
That is why I will put the other aspects on hold to help out the people
who decided to make a difference, to help out, to test the software,
report bugs, even fix them. These people will get my #1 priority,
because they have decided to make a difference. 

Some people have expressed interest in helping out with the webpages,
does anyone want to help design a main project page, with some form of
main menu, to show all the aspects of the project and give a direction
to people who come to the project for the first time?


I wish you all a great next week, I will be checking in, but will try
and stay out of the workings untill next week.

Thanks for you time, and your help.

Regards,
Mike

[Introspector-developers] Test of perl, gcc and cscc interface with an xml output the GCC-Introspector 0.5

[James M. D. <mdu...@ya...>]

Dear fellow hackers,

Here is a phase of the project I have kept secret for a while,
an interface between the c# compiler cscc, gcc and perl
via an c++ interface.

http://introspector.sourceforge.net/debian/
there are the debian packages,
i am uploading now.

dpkg -i file.deb
or 
dpkg-source -x file.deb
of the tgz with the source.

I hope someone will take a look.

Thanks a lot for your help, this project has got some interested
parties. I am doing my best to keep you informed, people have asking to
get more information. I am working on more and better documentation.

Please feel free to fill out the survey  :
https://sourceforge.net/survey/survey.php?group_id=19878&survey_id=13191

I would really like to get to know you better,

Mike

[Introspector-developers] Build instructions for the cywin ssa branch

[James M. D. <mdu...@ya...>]

Here are the steps to build the cygwin gcc with the introspector
patches


0. Getting the sources 
cvs -d:pserver:an...@su...:/cvsroot/gcc login
# password is empty
cvs -d:pserver:an...@su...:/cvsroot/gcc co -r
tree-ssa-20020619-branch gcc

0.0.1 Patch :
http://introspector.sourceforge.net/cygwin/ssa-branch-patch.txt

0.1 Configure, make 

---------------------------------------------------------------------
1. hacking libjava configure 

In the libjava/configure : 
I hacked the test for the java thread model.

echo $ac_n "checking for thread model used by GCC""... $ac_c" 1>&6
echo "configure:3165: checking for thread model used by GCC" >&5
#THREADS=`$CC -v 2>&1 | sed -n 's/^Thread model: //p'`
THREADS=none
--------------------------------------------------------------------
2. Hacking libmudflap

For LibMudFlap 
I added this file for the libmudflap execinfo.h

#ifndef _EXECINFO_H
#define _EXECINFO_H

int backtrace(int, int);
int backtrace_symbols(int, int);

#endif

--------------------------------------------------------------------
3. The standard make did not build libgc or libjava
these need to be built separatly

4. you can debug by adding these commands to the compiler :
-fdump-translation-unit -g  -save-temps  --verbose
then you can extract the sources.

4.1 The dumper crashes on the following file
and will need to be debugged. 
/gcc/i686-pc-cygwin/libiberty/floatformat.c

To get the commands
rm floatformat.o 
make floatformat.o > command.sh
extract that, add -fdump-translation-unit -g  --verbose

BUT DONT ADD -save-temps, it you add this, the error does not happen

/cygdrive/c/development/testing/gcc/gcc/gcc/xgcc
-B/cygdrive/c/development/testing/gcc/gcc/gcc/
-B/usr/local/i686-pc-cygwin/bin/ -B/usr/local/i686-pc-cygwin/lib/
-isystem /usr/local/i686-pc-cygwin/include -c -DHAVE_CONFIG_H -O2 -g
-O2 -I. -I./../../include  -W -Wall -Wtraditional -pedantic
floatformat.c -fdump-translation-unit -g  --verbose -o floatformat.o

The command line that crashed this was  :
 /cygdrive/c/development/testing/gcc/gcc/gcc/cc1.exe -quiet -v -I.
-I./../../include -iprefix
/cygdrive/c/development/testing/gcc/gcc/gcc/../lib/gcc-lib/i686-pc-cygwin/3.4-tree-ssa/
-isystem /cygdrive/c/development/testing/gcc/gcc/gcc/include -isystem
/usr/local/i686-pc-cygwin/bin/include -isystem
/usr/local/i686-pc-cygwin/lib/include -D__GNUC__=3 -D__GNUC_MINOR__=4
-D__GNUC_PATCHLEVEL__=0 -D__CYGWIN32__ -D__CYGWIN__ -Dunix -D__unix__
-D__unix -isystem /usr/local/include -idirafter
/usr/local/i686-pc-cygwin/include -idirafter /usr/include -idirafter
/usr/local/i686-pc-cygwin/include/w32api -idirafter /usr/include/w32api
-DHAVE_CONFIG_H -isystem /usr/local/i686-pc-cygwin/include
floatformat.c -quiet -dumpbase floatformat.c -auxbase-strip
floatformat.o -g -g -O2 -O2 -W -Wall -Wtraditional -pedantic -version
-fdump-translation-unit -o
/cygdrive/d/DOCUME~1/mdupont/LOCALS~1/Temp/ccJGy9eG.s

Here are the versbose output of the command :
http://introspector.sourceforge.net/cygwin/floatformat.bug

4.2 the dumper crashed on the following files
/gcc/i686-pc-cygwin/libstdc++-v3/libsupc++/del_op.cc

this command reproduces the crash : 
/cygdrive/c/development/testing/gcc/gcc/gcc/cc1plus.exe -fpreprocessed
del_op.ii -quiet -dumpbase del_op.cc -auxbase-strip del_op.o -g -g -O2
-Wall -Wno-format -W -Wwrite-strings -Winline -version
-fno-implicit-templates -fdiagnostics-show-location=once
-ffunction-sections -fdata-sections -fdump-translation-unit -o del_op.s

The file is located here 
http://introspector.sourceforge.net/cygwin/del_op.ii

can someone else try compiling this,
With a standard gcc 3.2 and the -fdump-translation-unit
and the gcc saa branch?

Thanks,

mike

[Introspector-developers] Function type diagram and a truckload of data files, rpm test files, old Talk about the Introspector

[James M. D. <mdu...@ya...>]

Documentation coming in by the truckload.

Here is a nice clean diagram,
shows how functions are set up. 
http://introspector.sourceforge.net/docs/introspector-function-type.png

Every scientific experiment needs source data:

Here again are a set of html files describing the tree nodes
I have removed the stupid index.html and you have a better list now
http://introspector.sourceforge.net/introspector-node-types/

we need a better indexing engine for all these files,
sorry.

the list of files uploaded is 
http://introspector.sourceforge.net/docs/files_list.txt

They are located here,
http://introspector.sourceforge.net/docs/

sorry about the temps!

Be sure to read 
http://introspector.sourceforge.net/docs/tree.html

this incredible excel sheet shows you
the types of fields the classes have
http://introspector.sourceforge.net/docs/Values2.xls

Here it is a monster html file
http://introspector.sourceforge.net/docs/ValuesOfClasses.html

Also, I have posted some rpms,
the freetype there are not good please test
http://introspector.sourceforge.net/alien/rpm/

Also, for all you gentoo hackers,
http://bugs.gentoo.org/show_bug.cgi?id=2626
here are the mingw stuff for gentoo
get it and start trying to compile stuff.

This is a talk that I held about the introspector 
at the YAPC::Europe.

[Introspector-developers] Tree structure UML and html files

[James M. D. <mdu...@ya...>]

http://introspector.sourceforge.net/introspector-node-types/node_base.html
This is a hyperlinked class model of the introspector.

Here is a rough diagram of the tree structure 
posted to the blogger :
http://gccintrospector.blogspot.com/2002_10_27_gccintrospector_archive.html


This should give you a guideline to the introspectors gcc tree model.

he project is made up of a few components.

1. The GCC patches
 The gcc patches give the ability to write the ASTs into XML.
 They also pipe the results into a perl script that reads them.

2. The perl XML reader
The processing of the XML is done in perl, first a class is
selected to contain the XMl and it is instanciated. The data is filled
into those objects. These objects are what you see in the diagrams.

3. The database access layer,
from those objects in memory we can then put the objects into the
database or get them out.

4. The Meta-Layer.
 there are lots of other code models for generating perl, java, sql and
all that from the descriptions of the nodes. This is meta-level code
that is not needed for interfacing into the gcc.

The cvs is available from the main project page.
http://sourceforge.net/cvs/?group_id=19878
http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/introspector/introspector/

Here are some overview of the files, the README 
http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/introspector/introspector/README?rev=HEAD&content-type=text/vnd.viewcvs-markup

Here is an example of the type of objects created.
we start with the generated perl classes for each expression type.

Here is the function call expression that will be instanciated 
whenever a function is called.

-------------------------------------
package introspector::node_call_expr;
# INHERITS
@ISA = qw[ introspector::node_expr  ];

# USES
use introspector::node_base;     # everything is derived from this.
use introspector::node_expr;      # the expr is the base class of the 
use introspector::node_tree_list; # the args are a in a list

sub  Getfn   { ... }   #   Get the function - this should be a
function_decl
sub  Getargs { ....}   #   Get the arguments - this should be a tree
list of arguments

-------------------------------------

These are your interfaces, They will be instanciated and called when
the trees are read in from the GCC.

Users can Derive and extend these classes with new functions, or write
functions
that take these as parameters.

Here is the cvs html branch.
http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/introspector/introspector/introspector/node_call_expr.pm?rev=HEAD&content-type=text/vnd.viewcvs-markup

The introspector collect meta information from the gcc and later perl,
dotgnu/pnet/c#, and also sql.

This information is then culled, selected into queries and layed out
with the vcg graph layout tool. Then the layout is passed to the Gnome
Dia UML drawing tool and from there can be hooked into emacs as an IDE.

This will provide with syntax highlighting of many different input
languages. I will build interfaces to existing system, creating data
piplines between them in a GPL static and safe manner, converting all
LGPL modules into GPL. I think the same for Artistic (clarefied) BSD,
MIT, X and also Mozilla? There are many tools available to be tacked
and glued on to make the best Free software reeingineering and
visualization tool.
