As we say in french "it's in the old pots that made the best soups".
Equate was originally written by Andrew Williams something like 8 years ago, and was using EWL and/or Edje for the GUI.
I didn't touch the math expression parser, but change the GUI, remove all the ewl and ecore_evas stuff, use Elementary for the window creation and keep edje for the GUI.
What i can said is that i'm impressed that after 8 years the originally edje file is still building without any issue, and the whole program is usable (except for the EWL part) !
I change the Edje file a bit to use new stuff like table instead of aligned objects by hand, but the old theme that you can find in OLD/MISC/equate is still usable as is.
