Thank you very much for the given answers.
Yes, my English is difficult to read and to follow: I did never learn English! Why not? Because I speak other tongues (French, my birth language, German, I live in Germany, Russian but without any praxis because I am old and it was very difficult to write it withe the computer and I have no typewriter for it. Latin and old Greek). And as the most influential person of the English world did assert BASIC English does enough, if it is/was not a fib, I know enough having worked through the book of C.K. Ogden ;-)) !
I did explain clearly the goal of my searching in the title of the thread:
- genealogy application in prolog
- for private use (clearly: not to be programmed by myself! This only reinforce the condition no. 1 “available”. For family uses!)
As I did understand, there is probably nothing although that is in total contradiction with the extremely frequent use of genealogy dates in Prolog examples , I did add two thematics out also extremely frequently used stuff:
b. nutrition (see the manual from Colmerauer (probably the first one manual about Prolog?)
c. languages processing.
you speak above on Fibonaci (hm, really, for daily family uses!!!) and search to convince it is some kind of stuff for private useful applications? Really? No, looking for the dark side of the moon would be more useful!
Referring to manual is certainly not acceptable: Thousands of manual on Prolog did be edited without to be able to project Prolog since about 1970 into the top ranking places.
For nothing excepted highly specialized environments and projects (like for Forth! Moore did reach, say the history, that ONE (unique!!!) hospital did be managed in Forth. And his telescope. But nobody can mention more project REALLY realized in Forth excepted the Big Forth monster from author of Gforth in his own home page!).
Thousands of Prolog professors at thousands of universities seem to let the arms hang and did never reach that some kind of usable application did emerge from the (collaborative) work of their student for other people to give confidence to ordinary people in their science! I live 300 meter far from a Textile University Highschool (where a lot of never used (some library cards are completely virgin although they are on the bookshelf all the time ) Prolog manuals did be bough. But they show all yeras complete clothes and not just collars or sleeves without the rest of the shirts! More, they organize all years a real complete mode show!
