[TeXmacs] inline plots in Maxima

Bill Eaton — 2013-05-21T16:12:45

I'm soliciting for help in getting inline plots working in Maxima. Maybe
there's already a feature that does this. 
 
I've had some success in getting inline plots working in Python and Octave,
it would also be nice to have them working in Maxima. The process would go
something like this:
   * create plot
   * save plot as eps file
   * call a new ps_out(fname) function to read the eps file
     and display it within TeXmacs document

The last bit could be a Maxima command that looks like this:
    print(ascii(2),"ps:",read_list("fname.eps"),ascii(5));

I have tried this command from a Maxima session and I get a display of raw
PostScript. The Maxima plugin seems to revolve around a Lisp file.
Regrettably, Lisp is a language I don't speak, so I don't know how to hack
it to get a function working. Algorithms so far have been:
   Octave: Drop a new ps_out.m function file where other plugin function
files are.
           Octave will see this file as one of the things to search when it
tries 
           to interp

Wow. That actually works quite well. Thank you. For both Python and Octave
plots. 

I was trying to do stuff I found on the right click menu like Set url... or
Show hidden. But those are hit or miss on whether you can trigger an update.


I still prefer the inline technique in many cases because it puts the figure
in the middle of my session and I can continue working on my maths.

RE: [TeXmacs] inline plots

Bill Eaton — 2013-05-20T18:28:58

Ok. I managed to get inline plotting working in Octave. It's kind of kludgy
at the moment, but it works. It should work with Matlab as well. Although,
if there are any differences it is possible to write one set of code that
autodetects if its running from Octave or Matlab and does the appropriate
thing.

What I did: Create a file called ps_out.m which contains

       function ps_out(fname)
         disp( [char(2) 'ps:' fileread(fname)' char(5)] );
       endfunction
This is slightly different from my earlier post. I put this file in the same
folder as a file called "tmrepl.m". In Linux this is found in
/usr/share/texmacs/TeXmacs/plugins/octave/octave/tm. In Windows, it's buried
in a C:\Program Files\TexMacs directory.

Here is a minimal example of how you might use this in a session on Linux:
  cd ~/
  x=1:10
  plot(x, x.^2)
  print 'test.eps' '-S500,300'
  ps_out('test.eps');
And voila! You should now have an inline plot. Ha! If you go back and tweak
things, you can quickly regenerate a 'test.eps' file an

[TeXmacs] Tensor indices

2013-05-20T11:05:25

Hello *,

In tensor calculus (as used in general relativity and in other areas of 
physics) tensors with many upper and lower indices are often used. Their 
order is important even if some indices are upper and some lower: a tensor 
can have, say, the first index upper, the second one lower, the third 
upper, etc. As an exception, if a tensor is symmetric in a pair of 
adjacent indices, and one of them is upper and the other one is lower, 
they are traditionally written with the indices on top of each other (a 
typical example is the Kronecker \delta_\mu^\nu - it is easy to write in 
TeXmacs).

So, i've written the following the following scheme function:

(tm-define (tensor . args)
     (define (process-args l u d)
       (if (null? l)
           `(concat (rsup ,(apply tmconcat (reverse u)))
                    (rsub ,(apply tmconcat (reverse d))))
           (let ((x (tree->stree (car l))))
             (cond ((== (car x) 'rsup)
                    (process-args (cdr l) (cons (cadr x) u) (cons `(hphantom ,

[TeXmacs] QT-TeXmacs + TexGraph + Eukleides on MacOS X

2013-05-19T15:20:15

Hi,

I've been trying for a long time to have TeXmacs and TeXgraph run on  
my Macbook Pro without success.

I tried recently with the Qt-port. I have texgraph installed both as  
an App and with the ./install.sh linux command from the source. It  
does not work. Inside a session, it tells me

  "cat: texgraphtmp: No such file or directory"

For eukleides session :

"Error at line 2: syntax error"

Does anybody has those plugins running on MacOSX + Qt-TeXmacs ?

Thanks for your help.

[TeXmacs] Update: Modifications to Texmacs Python Plugin To Accommodate SymPy LaTeX Output

David E. Miller — 2013-05-19T08:07:37

All:

Attached is a TeXmacs file that documents the latest efforts of the 
required modifications to the existing Python plugin required to adapt 
this plugin to a dedicated SymPy plugin. Also attached is the existing 
Python plugin file tm_python which I have modified to accommodate SymPy 
LaTeX output to TeXmacs.

It might also be possible to  use what I have done so far and merely 
modify the existing Python plugin to accommodate SymPy LaTeX output 
which is what I have accomplished here while preserving as much of the 
original Python plugin code as possible.

TeXmacs user Bill Eaton first brought the attention of users to this 
issue and several replies seemed to favor some accommodation for his 
goal. Personally I am not sure I will ever use this feature if it is 
brought to fruition, but the challenge sort of got under my skin, so I 
gave it a go and the results of what I was able to accomplish so far are 
attached. There are probably some sharp Pythonists out there that can 
see this through from her

I think I've come across the same problem. Months ago I was using Texmacs
1.0.7.18 normally on Windows 8, but one day this problem suddenly occurs. I
had to abandon it for a while. When weeks ago I found a new release, I
tried it. The problem was as before, but with a message box this time:[image:

I wrote to the bug-report twice, but each time got a delivery failure.

Days ago I recommended Texmacs to a friend of mine. I thought this is
simply a peculiar problem and Texmacs will work on his computer. But sadly
the problems occurs as well on his Windows 8.

Great! I'm new to texmacs so I'm not sure what existing works there are. 
If none, github is really the right place to make a tip collection. Much 
easier collaboration, free pages hosting, etc.

Looking forward.

[TeXmacs] Export in LaTeX

Emile L — 2013-05-18T13:06:22

I have imported an HTML page in texmacs (1.0.7.19-x11-i386 linux). When I
export the obtained tm file in LateX, I get the command \color{dark cyan} at
several places in the TeX file that pdflatex cannot handle.

The only colorss defined in the generated TeX file are :

\definecolor{grey}{rgb}{0.75,0.75,0.75}
\definecolor{orange}{rgb}{1.0,0.5,0.5}
\definecolor{brown}{rgb}{0.5,0.25,0.0}
\definecolor{pink}{rgb}{1.0,0.5,0.5}

There is no definition for dark cyan.

Hi all,

- Did someone set up a github repo or a certain shared document of the
"texmacs-tips" from this email list?

I think it will be great if we get the solution of a specific problem from
this email list, we not only fix it on our own PC,  but also paste it in a
online document or in a github repo.

- Previously I noticed the texmacs mind map by Yin Wang. It is great.
Can we edit this mind map?

[TeXmacs] TeXmacs Sympy plugin LaTeX Output Issue Solved

David E. Miller — 2013-05-18T06:15:24

The attached TeXmacs file documents a proposed solution to the main 
issue of developing a TeXmacs plugin for SymPy that outputs expressions 
to TeXmacs formatted as LaTeX.

I think there is probably a little more work that needs to be done by 
those that have an interest in this plugin, but it appears the the main 
hurdle of formatting the output is solved.

Comments and suggestions are welcome.

You should have a list of all the sections in the focus toolbar when the

Re: [TeXmacs] Sympy plugin

David E. Miller — 2013-05-18T03:04:31

Greetings François:

For the sake of those TeXmacs user that are not familiar with SymPy, you 
should not need a dedicated plugin.

Merely start a TeXmacs Python session and load the sympy module,

[Python from sympy import *

or use some other import statement form to get at the sympy module 
namespace of interest.

This is all a SymPy plugin would do for you and this way the user has 
control over what is imported.

The same is true for any number of other Python modules -- NumPy, SciPy, 
Scientific Python, Scitools, Matplotlib, Oct2Py( Python-Octave 
interface) , and others.

However, if you want the kind of quality of displayed output that say 
the Maxima plugin provides, then more is required. This is the context 
of the issue that was raised about SymPy -- how to get the output to 
display in the same way TeXmacs displays math expressions. The existing 
Python plugin does not provide this capability.  Maybe some of the 
developers can help in this effort. However, then the natural question 
that arise
