CLI tool for doing set operations (e.g. intersection, difference, union) on lines of input

Project description


CLI Tool for doing set-operations on lines of input. Each line is treated as an item in a set. Each input is treated as a set.


usage: kvenn [-h] [-n] [-s] [-f]
             [-o {+,-,x,d,union,difference,intersection,unique}]
             sets [sets ...]

positional arguments:
  sets                  Each file is a set and each line in the file is a
                        member of the set

optional arguments:
  -h, --help            show this help message and exit
  -n, --non-empty       non-empty values only
  -s, --strip           strip surrounding whitespace
  -f, --filter          strip and filter to non-empty
  -o {+,-,x,d,union,difference,intersection,unique}, --operation {+,-,x,d,union,difference,intersection,unique}
                        Operation to perform on the sets [-] Subtract sets
                        1...N from set 0 [+] Get the union of sets 0...N [x]
                        Get the intersection of sets 0...N [d] Symmetric
                        difference (disjunctive union). Elements from all sets
                        which are not in any others.


Unique values in a file

kvenn <input>

Unique values in two or more files (Also --union)

kvenn <input1> <input2> <inputN>

Values found in both files

kvenn <input1> <input2> --operation intersection

Values found in only one file

kvenn <input1> <input2> <inputN> --operation unique

Values found in only one file

kvenn <input1> <input2> <inputN> --operation unique

Subtract values in B (and C, D.. etc) from A. (Unique values from A)

kvenn <inputA> <inputB> [<inputC>] --operation subtract
