Re: [Texmacs-dev] Octave plugin status

[Denis RAUX]

It's completely right when i integrate a plugin in the windows version, i make 
the very simple test  1 + 1. The main reasons are i have no idea how they 
should work and no left time to dig. So a windows port must be  similar to the 
linux version.  

Concerning the Octave installation, I fetched a true windows package with an 
installer : octave-3.6.2-vs2010-setup.exe. I don't remember it was painful to 
install. If you make the installation in the standard locations, texmacs must 
find it automatically. 

I didn't know anything about the plugins author intentions  when he wrote it. 
But if you want make Octave running with the test cases you gave, you have to 
modify the  tmrepl.m file located in C:\Program 
Files\TeXmacs\plugins\octave\octave\™

 function tmrepl()
        prompt=sprintf("%cchannel:prompt%coctave> %c",2,5,5);
        while ( 1 )
                r=input(prompt,'s');
                eval(r,"tmlasterr");
        endwhile
endfunction


This should give to you :

 octave>  A = 1 + 2

A =  3  
octave>  B = [1,2,3]

B =

   1   2   3

octave>  5 + 5

ans =  10  


I hope this will be convenient.
