To find the formulas and behaviour described you can also check
http://docs.gimp.org/2.8/en/gimp-concepts-layer-modes.html.

You will probably have no luck if you look in GIMP for the blending
modes. They are already ported to GEGL, so you will have more success
looking in the GEGL sources.
You find the GEGL API documentation at http://gegl.org/operations.html.
The section 'Compositors' is your friend ;-)

Make sure, you have all necessary tools and dependencies installed.
See also our developer wiki for more information:

To discuss development related questions, feel free to join the
Gimp-developer or Gegl-developer mailing lists.

Good luck + kind regards,
