)set output texmacs

     --------------------------- The texmacs Option ----------------------------

      Description: options for display of AXIOM output in TeXmacs

      )set output texmacs is used to control the TeXmacs-AXIOM interface
     The default values are controlled by environment variable TM_AXIOM
     and may be overriden by command line options.

     Syntax:   )set output texmacs <arg>
         where arg can be one or more of
       break <on>|<off>      line-break algorithm
       over <on>|<off>       convert 2-d \over to 1-d
       cdot <on>|<off>       convert \cdot to \ (space)
       space <on>|<off>      convert \ (space) to \,
       big( <on>|<off>       convert \left( \right to ( )
       width <9.99>          line width in inches

         <on> may be on, yes, 1
         <off> may be off, no , 0

     The current settings are:
       break 1, over 1, cdot 1, space 0, big( 1, width 4.5

->draw(sin(x),x=0..1) Compiling function %D with type DoubleFloat? -> DoubleFloat? Graph data being transmitted to the viewport manager... AXIOM2D data being transmitted to the viewport manager...

(1) TwoDimensionalViewport?: "sin x" Type: TwoDimensionalViewport?

But no picture was created. Does draw() still not work in this verion? Anyway, Axiom is excellent CAS and I will introduce this in my calculus class. Thanks!

I suspect the problem is that the axiom interface module is calling FRICASsys (the actual axiom interpreter) rather than the axiom shell script. The axiom shell script starts the sman (superman) process which starts FRICASsys, the hyperdoc browser, and the graphics connection. If you call FRICASsys directly then graphics will not work.

Please open a command terminal, set your AXIOM variable and PATH variable, and type axiom. Then retry the draw command. Please let me know if this succeeds or fails and send a message to the axiom-developer@nongnu.org mailing list.

Graphics still--John Sheppard

Sat, 19 Feb 2005 15:07:52 -0600 replyI too have problems displaying graphics. I finally managed to get the Windows version of axiom to work with the windows (non-cygwin) version of TeXmacs (i.e., WinTeXmacs?). I tried the draw command from the axiom tutorial, both in axiom and from WinTeXmacs?. Here's the sequence:

s := operator 's DE := D(s(t),t,2) = -k^2s(t) - cD(s(t),t) S := solve(DE,s,t=0,[A,0]?) S1 == eval(S,[A=1,k=1,c=3]?) draw(S1,t=0..100)

Following the compiling of the draw function, I get:

Graph data being transmitted to the viewport manager...

>>System error: SOCK-SEND-INT is invalid as a function.

protected-symbol-warn called with (NIL)

This same error appears both in axiom alone and in WinTeXmacs?. Any ideas for solving this would be appreciated. If I need to set the AXIOM and PATH variables, as suggested above, what should they be set to? You can respond to me at jws@cablespeed.com if you wish.

Thanks, John Sheppard

System error: Caught fatal error [memory may be damaged]? protected-symbol-warn called with (NIL)

Forgive my stupidity but ... any help??

Also can the axiom help/reference be lanched from within the TeXmacs as it can be done using MuPAD? from TeXmacs.

axiom is a script that launches sman (superman). sman starts hyperdoc, FRICASsys, and clef which is a command-line completion program.

I don't know but I suspect "clef" is getting in the way. Try changing the call to axiom to use axiom -noclef and see if the behavior changes.

Is it possible to get rid of the first prompt? Having prompts not preceeding user input is very annoying.

Is there a possibility of using the hyperdoc type in the commands in the TeXmacs interface (to get a nicely formatted output)?

Axiom hyperdoc is not required to get nicely formatted output in TeXmacs. FRICASsys generates Tex/LaTeX output that is processed by TeXmacs.

Could you please describe what effect you would like to achieve in TeXmacs? In what way is the current TeXmacs output not nicely formatted?

Can someone tell how this can be done or change the tm_axiom and distribute the code.

Any help is welcome.

There are a lot of things that can be improved in TeXmacs. First of all an online reference would certainely help a lot (those who are Turbo C IDE fans would know this)--one just presses some hot key and gets more information on the command he wishes to use and is not so sure about. He can get some examples on how to use the system, just fill in some entries and get the command output without having to learn hundreds of functions. This would be most beneficial to users new to axiom and to those who have just started to use Computer Algebra Systems. Not only that, this I think would save time of those users who are just using the interactive axiom and not programming with it.

Unfortunately, not a lot of resources are available to do this. At this time, the only person that I know who is working on this is Andrey G. Grozin. See

http://lists.gnu.org/archive/html/axiom-developer/2005-08/msg00229.html

Instead of starting FRICASsys, it should start axiom -noclef

Also, in void session(void), declare:

  int prompts=0;

and, a few lines later, replace the line:

  else if (code==PROMPT) break;

by the line:

  else if (code==PROMPT) { if ((++prompts)==2) break; }

However, it would be much better to fix this damn double-prompt problem once and for all. Axiom must not write a prompt when it is not prompting the user to input something.

save the following as a file and do a 'perl file tutorial':

        use strict;
        use warnings;
        use Cwd;

        use File::Find;

        my $read_dir=$ARGV[0];

        my $top = getcwd();

        find(&d, "$top/$read_dir");

        sub d
        {
          my $file = $File::Find::name;

          if (-f $file && $file =~ m/\.tm$/)
          {
                  print("found tex style file $file\n");

                  `mv -v $file $file.bak`;

                  open(IN,"$file.bak") or print("couldn't open $file.bak\n") && next;
                  open(OUT,">$file") or print("couldn't open $file for writing\n") && next;

                  while(my $line = <IN>)
                  {
                          $line =~ s/\|axiom\|axiom/\|axiom/g;
                          $line =~ s/axiom-tutorial\|axiom/axiom\|axiom-tutorial/;
                          print(OUT $line);
                  }

                  close(IN);
                  close(OUT);
          }
        }
