[Gmath-devel] Project status

[Hassan A. <au...@DM...>]

 Hi, 

 You probably noticed the project is stalling a bit. 

 However it is not dead. I am just having a lot to do right now: a new born boy, 
a math thesis to finish and a full time job. 

 Coding will resume at a slow pace in January and will probably return to 
standard early pace by next June.
 
 So please be patient, and in the meantime, feel free to help by contributing 
directly.

[Gmath-devel] RPMS disappeared

[Hassan A. <au...@DM...>]

 Ok RPMS seem to have disappeared from Matias's page. 

 Any know why? 

 Anyway, I will try for 0.3 release to have it RPM friendly. Any help with deb 
friendly is welcome too.

how about using TeX for this ?
Maybe an expression can have a context-menu with an option to display
it using TeX ?
or a terminal-command or both ?

This should be easy because TeX is very tree-like:
(x^2 + 7*x^2)/sin(x) => $\frac{x^2 + 7x^2}{\sin x}$
So you can just convert the expression-tree recursively.

the advantages are that you don't have to care about boxes and symbols and
you get a high-quality output. the disadvantage is that it takes a few
seconds to come up, so it is most probably not appropriate for
inline-graphics.

 Well thanks for your comments. Now, if you could be more precise 
about cut and paste. I don't really understand or your question is 
trivial. Do you really mean cut and paste, or is it drag and drop?

 This is a tough one. Ok, for now gmath's session is really a terminal 
session with some hopefully nice user layer.

 Think of it a Mathematica 1.0 but looking better. The next step for 
me is to leave this interface for terminal sessions, and write a new one. 

 However for now, gnome/gtk text widgets are ugly and useless. I 
thought about the canvas but that would be too much work, and I don't 
want to do it.

 This simply means that I have to wait for gnome/gtk folks to finish 
writing pango. Pango is a niftier text widget with support for all 
kinds of input and for unicode.

 Again this means that when all is done, we would be able to display 
just about anything in those, including math symbols and such. 
Otherwise, you need to write those symbols yourself or have the kind 
of resources Wolfram has to create Mathematica.

 So for now, think of GmatH, as a nice numerical simulation 
environment, where you can compute, visualize, save sessions, then use 
them as starting point for coding more complex stuff, soon code, debug 
....

 We will take care of presentation later.

 I have not yet looked at those things. Ayal Pinkus the creator and 
maintainer of Yacas should be able to help you more with that.
 He is on the list yell Ayal.

 I agree, but have no fear since no embedding will happen for now. As 
far as I am concerned. I'd like to have a full-fledged data 
visualization thing, a coding/session/debugging thing, a presentation 
thing. But that's far still.

[Gmath-devel] Mathematical Symbols

[Klaus N. <kl...@xo...>]

Dear Hassan,

I think your Project sounds very nice and indeed it is a good idea to
provide a generic user-interface for mathematical programs. I have been
using for sometime Maple and though I confess that I use most often
text-mode, I really like the cut and paste functions of this program. I
don't know how mathematica looks like, but I guess similar.

Are you planning to implement such cut and paste functions for your
project? Are you able to display fractions, greek letters,
integral-signs and so on? (For greek letters Pango should do it, I guess
and I think it will be soon used as default for Gtk anyway, but
fractions and subindexes and things is probably difficult.)

I'm not sure if I really want to participate, but I will have at least a
look at your program.

By the way, when I was doing my master thesis I developed a small
algebra-program and the thing I really found annoying was, that I had to
program the parser that transforms all those term like [[a,b]+5c,d] into
a tree structure myself. Could you tell me if you know a standard
library for this, please.

Thank you for your effort and I will watch your program with interest.

Greetings
	Klaus Niederkrueger

A suggestion: The reason why I don't use Xmaple anymore was that they
switched from the nice Unix-interface to a windows interface. I explain:
In older versions everytime you made a plot, a new window was opened for
it. In their newer versions the plot is embedded into the worksheet and
you cannot move a subwindow out of the mainwindow. Though this at first
looks really very compact and elegant, I think is really antiproductive.
I think if you write a text it may be normal to have just one window
open, but for mathematics this is not the case.

[Gmath-devel] News of the front

[Hassan A. <au...@cr...>]

 Hi,

 This is a copy of what was posted on the gmath-project/News section.

 Hi guys/garls, 

 			I am pleased to announce that Janko Hauser and Matias
Mutchinick are now part of this little project. 

                       Matias has been the first to create rpms and will
continue to do so, maybe more?


                       As for Janko, I have taken the liberty to use his
excellent short reference
                       documentation (getting longer by the week) on Numerical
Python and integrated it
                       using his tools and the new gtkhtml to obtain something
I'd like to call nifty. 

                       Even though this is not released yet, because of many
worries, gtkhtml still a bit
                       weird, gnome-python going through a major overhaul ....,
you can have a look at
                       the screenshots which will be updated sooner than the
software itself. 

                       I cannnot promise any near release, but I'd say we will
have a nifty one in
                       July/August. 

                       In the meantime, enjoy the screenshots below:

Re: [Gmath-devel] Problems running gmath

[Hassan A. <au...@cr...>]

 This error is kindda weird. Anyone else experiencing this?

 The usual is that you also need pygnome, gtkextra and pygtkextra.

 I know this is a very long list, and I am looking into ways of making 
it smaller but for now, you need all of those packages plus python of 
course.

 I really don't know what could have gone wrong.

 The function causing problems is correct. 

 Can you try to uncomment it? Then run the script again?

 Ok,
 
 I am looking at suggestions. I have already looked at another NumPy doc that 
looks like Python online docs.
 
  What I really would like to do is have:
  
  -A way of retrieving from a stable web page the TOC of documentation that I'd 
then put in a custom gnome-tree-like widget and when the user clicks on one item 
it'd open a link to online corresponding page.
  
  -An entry widget that'd have a search item that look in index of docs (online) 
and return all possible choices then when user chooses one show the 
corresponding page.
  
  -A bookmarking facility so that users can go back quickly to places they have 
seen.
  
  -The choice to download the whole .tar.gz thing to browse off-line.
  
  
  
  All of the above is easy to implement, and I have already started doing so 
with GMatH (http://gmath.sourceforge.net), provided there is a known stable 
place where to look for these docs.
  
  I already have a place to look for, but I forgot the address.
  
  All I need is some nifty .py thing that'd fetch the TOC, and index (from web 
site) and search through that index. I am not very good with urllib or httpblib, 
so any help is welcome.
  
  
  Thanks

[Gmath-devel] Help needed

[Hassan A. <au...@DM...>]

Is it possible anyone out there would be nice enough to turn GMatH into an 
autoconf/automake/rpm/deb ready? It shouldn't be too hard since it's in Python 
and there are no powerful/cryptic Makefiles.in/configure.in to write. 

Also, another thing that I would like to see is one gmath.c file that could get 
compiled and that would be a replacement to the present gmath script created at 
install time. 

The point here is to have a gmath process appear under top. For as a python 
script, you don't get to know which process to kill since all their names are 
python. 

Of course as usual, I am asking for help because I am an autoconf/C/automake 
illeterate.

Thanks,

H. Aurag

Re: [Gmath-devel] GMatH News and Questions

[Adrian F. <fe...@ma...>]

What you have to do is to parse the color you want, "light blue", for
example, using gdk_color_parse. Then you get the fields
color.red/green/blue. After that you use gdk_color_alloc to get the best
match according to your X color depth, you don't have to care about that.
Hope this helps,

 I was really talking about available colors and not all colors. It

available colors depend on your X depth (8 bit, 16, 24, 32)

[Gmath-devel] GMatH News and Questions

[Hassan A. <au...@cr...>]

 Hi all,

 Well it's been a waiting period for GmatH. I am still waiting for a 
working gtkhtml widget and its python bindings. 

 The plan is to have html-based integrated help within each session. 
For instance yacas for now uses lynx to show help, I plan on making it 
use an internal gtkhtml widget to show it and show the contents of 
this help. Same thing with Numerical Python. 

 On another front I am still discovering all the facets of gtkplot. It 
really is cool as it allows for instance realtime plots among other 
things. I still don't know if it is possible to edit the plots on the 
fly for legends, labels and captions. 

 What I really want is to be able for instance to plot something, then 
edit the paper sheet where it is, add other plots (easy), write some 
text, etc.... Ideally it would be stripped down math-word processor 
where you can type some text add some formulas and such then print the 
sheet as an eps and insert it into your article, presentation ....

 Now comes the questions period. I am trying to implement among other 
things real-time plotting. You would create a function that returns a 
point/curve at given intervals and then the RTPlot command would take 
this as its arguments, and add the plot accordingly with proper 
identification. If you have points depending, it would just plot the 
thing and join the points if needed. If you are plotting curves that 
depend on time, then it would the curves in normal x,y coords and add 
a legend to each one, say time t=0, t=5, t=10 etc... Of course this 
has some limits, the number of colors you have on your system.

 Now comes the real questions:

 -Anyone knows how to get the rgb list of colors on your system, or 
the gnome strings associated with them?

 -Anyone knows what should happen if you wanted to interrupt the 
process for any reason?
 Would you want it to save its state, then maybe restart after 
corrections, dump everything, have the choices but then which choices? 
Any suggestions (reasonable) accepted!

I think this "ps" thing - although it's not critical at all - should
be fixed, because as you can see it is deprecated. But I don't think you
have to move to another module - maybe just tell the maintainer
to change this ?

[Gmath-devel] Re: scientific python

[Hassan A. <au...@cr...>]

 Yappa di doo or more humanly agreed.

 We need to build a database of such stuff. Anyone care to do that?
 
 Any thoughts about how to do it? I need some kind of tree like list 
of packages for numerical python (xml?) that could be parsed by 
python. It would be placed on GmatH web page (hidden) and parsed by 
GmatH to check where packages are and what version. Something like:

 all = [list of all packages]
 NumericalPy, $version, $rpm_address/None, $tar.gz address/none
 Cephes,	$version ......

 Then we add a widget that would have a shipped list of packages but 
could "update" the list and packages from the web by fetching this 
tree-like file.

 This should be easy to do but needs a maintainer other than me.

 Volunteers anyone?

[Gmath-devel] scientific python

[Adrian F. <fe...@ma...>]

Hi Hassan. You posted a mail a few days ago about a code for derivatives
in python.

Did you take a look at scientific python? It looks like a natural
extension to numpy, with derivatives, less-squares fits, etc.

I think it worth it to be considered for gmath.

What do you think?
Regards,
<ADRIAN>

Re: [Gmath-devel] install fails, more installation instructions

 Ok,

here is my take at those bugs

 Is this the gnome dir? My default is /usr/share/gnome, but anyway I

 This means your site.sitedirs[0] does not exist even though python 
has it in its array of site directories. I am trying to get the first 
site-dir and it seems to fail. I will try to solve this.

 This is not normal at all, the readline module is a standard module 
in python. What is your python's package version? What distro do you 
use?

 Agreed, I am trying to figure out an intelligent way. The problem is 
that I use rpms and RedHat but you might not. 

 It is also difficult to coordinate with all package managers so that 
I am sure http://foo.bar has got the latest package always.

 I need something like Helix Code updater, and this means putting the 
packages on my site and make you go get it.

 In any case, I will be making it simpler for RedHat users soon. For 
others, I will need help from those who use it since I can't really 
afford to have 10 machines with ten distros or one huge machine with 
Vmware and all distros.

 Nope, there is a small handle at bottom of window that does resizing. 
It separates Quick help from terminal

 This will be changed into a try then bail if yacas not found. I tried 
this part only on my system.

 This is a stupid bug that has been fixed in CVS

 Ok the rest here is about ps. I am using a ps that might not be 
yours. I have been unable to find a good resource tracking module in 
python. The normal "resource" module is cryptic and does not work for 
children processes. Anyway, I will disable this if it screws your 
system.

 This is easy, it is related to the fact that your gnome help files 
were not where I expected them. It should now be fixed in CVS

Re: [Gmath-devel] install fails, more installation instructions

[Hassan A. <au...@cr...>]

 Seems like a lot of bugs to me.

 Please give me a week or so to look at the whole thing and how to 
solve those issues.

 But thanks a lot for this report, I need more of those.

 What version of python do you have btw?

[Gmath-devel] install fails, more installation instructions

[Felix N. <f.n...@nd...>]

hi,
- when running ./INSTALL (as root):
mkdir fails (directory does not exist)
and so on
it creates a file at /usr/local/lib/python1.5/site-packages
which contains "GMatH" (probably some problems in a shell command ?)
if I then remove this file and create the GMatH-directory manually,
everything works fine, except that in a numerical-python -session, python
can't find a module called "readline".

When I first took a closer look at gmath, I didn't install it because it
required numerical python (which I figured would require me to install some
weird packages; and when I felt up to it, I couldn't find a link). So I
think you need to make it easier for someone who is not actively using
python to install all these:

installation instructions:
* get python-1.52 from www.python.org and compile with --with-thread
* get gtkpy from www.gtk.org->python binding and install it
* get gnome-python from a gnome-mirror and install it
* get numerical-python (either RPM-packages or from numpy.sourceforge.net)
        * get distutils before that
(the numerical-python-RPM's didn't work for me (my path to python is
/usr/local/lib/python1.5/); though maybe this is my fault)
* install gmath ;-)

BTW:
* the help-windows are too small horizontally (I didn't see this in
screenshots, so this may be fixed)
* I get lots of warnings and errors, and in the case of the yacas-session,
it crashes after starting (I do not have yacas installed).
here's a session where I started a yacas session (but I am using the
developer gnome, so it may be because of that ..?)

[Gmath-devel] GMatH version 0.2 is out

[Hassan A. <au...@cr...>]

 GmatH is the Gnome Mathematical Interface. Its goal is to provide 
command-line mathematical tools with a nice and "integrated" GUI.

 For now it supports Numerical Python (35%) and Yacas (5%) and has 
basic data visualization using gtkplot (5%).

 Version 0.2 is the last gnome 1.0 oriented release. It should not be 
stable enough though as I was tired of doing it to scrap it a week 
later and replace a lot widgets with new ones.  

 Please check http://gmath.sourceforge.net for more info!

 Have fun and submit bug reports and give some help
