I am trying to auto-generate a diagram from a Python script in my Lyx document
using the "External Material" function. I have created a Python script called
"myscript.py" which generates a diagram and saves it to "myscript.pdf". I am
trying to make Lyx run my script to generate the diagram when I export my
document to PDF.
I added the following to the Lyx external_templates file:
Template Python
GuiName "Python: $$AbsOrRelPathParent$$Basename"
HelpText
Python diagram.
HelpTextEnd
InputFormat "*"
FileFilter "*.py"
AutomaticProduction true
Preview Graphics
Format PDFLaTeX
Product "\\includegraphics{$$AbsPath$$Basename.pdf}"
Requirement "graphicx"
UpdateCommand "python $$AbsPath$$Basename.py"
UpdateFormat pdf
UpdateResult "$$AbsPath$$Basename.pdf"
Requirement "graphicx"
ReferencedFile pdflatex "$$AbsPath$$Basename.pdf"
FormatEnd
TemplateEnd
However, when I insert the Python script in Lyx, it draws a box that says
"Error converting to loadable format". If I try exporting to PDF using
pdflatex, I get the following error:
"Missing $ inserted. Missing { inserted. I've inserted a begin-math/end-math
symbol since I think you left one out. Proceed, with fingers crossed."
If I export to Latex using pdflatex, it seems to export correctly, and my text
file contains something like this:
begin{document}
\includegraphics{C:/Documents and Settings/MyUsername/Desktop/myscript.pdf}
\end{document}
However, it doesn't run my update command, i.e. doesn't run the Python script.
(I've even tried changing my update command to things like "echo test>
output.txt" but I can't seem to get any commands to run at all.)
Any ideas what I am doing wrong? I've tried on Lyx 1.6.3 and 1.6.5-1 on Windows
XP.
