Re: Suggestion of new program: execute mathematical set operations on lists

Hi Frank, In my opinion if you need the tool, write it - don't worry about what anybody else thinks. If other people want it as well then that's the point to worry about distro support. Cheers, Roger

Re: Suggestion of new program: execute mathematical set operations on lists

Hi Frank, I think I know a language that will do what you want, it is called LISP! Lisp stands for `list processing language' or `lots of irritating superfluous parentheses' when it doesn't. Lisp allows you to program as if you were writing mathematics, aka functional programming. I learned Lisp

Suggestion of new program: execute mathematical set operations on lists

Hello everybody, I am not yet looking for a sponsor, but going to program a tiny tool: "setop" takes as inputs several lists/sets, calculates desired (mathematical) set operations on them and outputs the final set (or depending on operation resulting number of elements, answer yes/no, …).

Re: Suggestion of new program: execute mathematical set operations on lists

Hi, a quick googling returns me this link [1] seems that python natively do some sort of this python3 >>> a = set([3, 3, 2, 5, 1]) >>> a {1, 2, 3, 5} >>> b = set([5, 90, 2, 7]) >>> b {90, 2, 5, 7} >>> a | b {1, 2, 3, 5, 7, 90} >>> a & b {2, 5} >>> [1]

Suggestion of new program: execute mathematical set operations on lists

Hello everybody, I am not yet looking for a sponsor, but going to program a tiny tool. Because I am unexperienced and don’t want to do all the work for nothing, first of all: Is this tool senseful, is there a certain need for it? I am very interested in your opinions, hoping that this list is

Re: Suggestion of new program: execute mathematical set operations on lists

Well, I had once programmed a tool like this called mset (multiset) and it is still on my hard disk though releasing it would require some kind of testing and quality assurance (I call the package leutils). First of all the xchroot package I have just released would need to get accepted before I
