how to associate .pde with processing

Question

On Ubuntu 14.04 in order to click on a PDE file and associate processing.

Clicking launches gedit, the default for text files. right clicking on the icon shows the different programs that could be executed, and clicking additional lists a lot more, but not processing.

Processing is at this point installed at:

/opt/processing-3.06b/

so I added that to the path, but that did not add it to the list of applications.

There does not appear to be any way to execute an arbitrary command.

You need a desktop file:

1. Create a desktop file

   nano ~/.local/share/applications/processing.desktop
   

2. Add the following entries

   Replace the attribute for Path with a valid icon path and note the %f. That's necessary to open a file in your file manager with this desktop file.

   [Desktop Entry]
   Version=1.0
   Type=Application
   Name=Processing
   Icon=/opt/processing-3.06b/processing.png
   Exec=/opt/processing-3.06b/processing %f
   Comment=Processing is a flexible software sketchbook
   Categories=Development;
   Terminal=false
   StartupWMClass=Processing
   MimeType=text/plain;

3. Open your file manager and navigate to a PDE file. Open the Properties dialog and the tab Open With. Search the entry Processing in the list and use the button Set as default
