A thread for program ideas

Question

I wanted to make a place where people can come to get ideas from others or to give others their ideas for programs. If you have an idea, post it here so we can help you with it and see it done. If you are at a roadblock and need an idea, you can come here to find inspiration for a code. If you need help with your program idea then you can get help from others to get it done.
Please, to make this successful, only post on what this was meant for - program ideas and helping others.

Answer 1

@J.G. In a more advanced form one could make a user interface where one could place the figures but u could also tell the user to write the position in a text file in a human and machine readable way like:
Rb,Hb,Bb,Qb,Kb,Bb,Hb,Rb
P,P,P,P,P,P,P,P
e,e,e.......
where P=Pawn,Hb=HorseBlack,e=empty field....
Then a console application that would ask for the file path to the games and the file path to the user specified position would be sufficient.

Answer 2

@Arcturus So you would select one board position, from anywhere in the game? How would you select which board position to display?

Answer 3

Well for those of you who play chess...you could try to make a program which parses pgn (portable game notation) files which contain chess games in algebraic notation and lets the user get all games where a certain position was on the board...I tried to implement this once since online chess servers (like lichess) allow download of all your games but don't offer this kind of search....this might be implemented somewhere already and is of course of limited general use
