Re: [Inkscape-devel] Problem with the Latex Formula module
Sorry, my first message was meant to be addresed to the list.
Could you try with the latest svn version of the extension script and give us feedback?
http://inkscape.svn.sourceforge.net/viewvc/inkscape/inkscape/trunk/share/ext...
It is better, I have now a window message :) :
dvips: ! DVI file can't be opened.
[…]
Yes, it's better!
Now I guess you got this message because the formula input you gave to the extension was either not valid LateX, or it became invalid because of a shell expansion which occured when the script was called by the extensions manager (this is a bug).
Can you try with a simple "( \cos(x) )" LaTeX input?
To know how your imput will be expanded you can use the following shell command: $ echo -E "$$\cos(x)$$" 8012\cos(x)8012
For example '$$' is expanded to the pid of the processus. As a workarround, try not to use '$' or '$$' but '(' and '[' instead to enter math mode.
Stéphane.
PS: I'll also try to improve error reports when the given input is not valid LaTeX.

Actually I've tested it with the default input (so without $$).

Here the result :

ValueError: invalid literal for float(): 210mm
Various extensions have used a routine for converting these units to user units. I've just moved it to a central location in svn: inkex.py.
user_units = inkex.unittouu(string)

All right,
What should I do ?
Use the lastest inkex.py and updated eqtexsvg.py.
Also, if you have some spare time, I'd like some testing of a new version on as many platforms as possible. This version includes better temporary files management, and improved invalid LaTeX input errors, see:

Thanks, Stéphane

Thanks, it almost work. I have this error message (autopackage inkscape200611241751, inkex.py Revision 13431, eqtexsvg.py Revision 13446, eqtexsvg.inx Revision 13439 ):

however, this file /tmp/inkscape-fX_GpE/eq.svg exist and I can open it with inkscape (file->open), so I can now make nice picture with equations.
Just to notice, along with the equation there is also a white rectangle in the file.
Also, if you have some spare time, I'd like some testing of a new version on as many platforms as possible. This version includes better temporary files management, and improved invalid LaTeX input errors, see:
I tried several one-line equations and that's ok for the moment. I'm using an ubuntu edgy (i386) on a dell D610.
Thanks again,
J.L.
Hello,
I solved the problem by adding time.sleep(0.5) before svg_open(self, svg_file) in the eqtexsvg.py.
(With the latest inkscape package, inkex.py, eqtexsvg.py and eqtexsvg.inx)
