Hi Denis:

I have not been able to get the Octave plugin to work correctly on any 
version of TeXmacs up to and including 1.0.7.18. This includes the MS 
Windows, OS X, and GNU/Linux ports/packages. I use GNU/Linux 95% of the 
time. However, I am not familiar with the Octave installer package in 
the form of an executable that you reference below. I personally don't 
plan on using the MS Windows version of TeXmacs, and so I will probably 
not install any MS Windows Octave port again in any case. I plan to stay 
with GNU/Linux (Lubuntu is what I use) and forgo all of these extra 
compatibility issues.

However, I am interested in knowing whether or not the installer you 
reference modified the the PATH environment by adding the path to the 
Octave executable? The TeXmacs Octave plugin will not work at all if 
this is not done either by the user or by the installer. The Octave 
session will be missing or dead in that case.

It might be of value for you to send a email message to the user list 
with the URL link to the octave-3.6.2-vs2010-setup.exe you reference. 
The package i used was from a link located on the Octave project website 
page. It is not "painful," but it is "clumsy" by my way of thinking - 
certainly not a typical "click-and-go" executable installer program like 
you reference..

Also, thanks for the tip on the plugin modification. I have not tried 
this yet, but it looks like this addresses the Octave plugin anomaly I 
describe. I will let you know as soon as I get a chance to take a swing 
at this. If this modification fixes the issue, then this needs to be 
conveyed to the TeXmacs developers, and then hats off to you for fixing 
this.

I have been using Octave through the Oct2Py Python module from a TeXmacs 
Python plugin session. This has worked flawlessly so far, but a 
standalone Octave plugin that works correctly would be nice to have.

Best Wishes,
