Hi all,

In Viper, FFC, and Instant there are Python scripts like viper, ffc,
ffc-clean, instant-clean, and instant-showcache. In Windows you cannot
execute these scripts by themselfs, even if they are in PATH (unless you
are using MSYS or Cygwin), so if you for instance want to display a mesh
with Viper, you can't do

  viper mesh.xml

but you have to do

  python <installation_prefix>\Scripts\viper mesh.xml

This is not very useful and breaks the code many places (like plotting in
DOLFIN). A simple solution is to create a batch file (e.g. viper.bat) that
executes the line above. The batch files are installed together with the
Python scripts into <installation_prefix>\Scripts and after adding this
folder to the PATH environment variable, one can start the scripts as one
would expect (no need to specify the .bat extension). I have created three
patches, one for each of Viper, FFC, and Instant (see attachment). Feel
free to modify the patches as you like.

Johannes
