Setz is a command line utility used to run set operations on files using python syntax

Usage

setz “query” [a.txt b.txt ..]

Possible Queries

Set Membership. Test if an element belongs to a set.
“‘test’ in a”
Set Equality. Test if two sets contain the same elements.
“a == b”
Set Cardinality. Return the number of elements in the set.
“len(a)”
Subset Test. Test if a given set is a subset of another set.
“a < b”
Set Union. Find union of two sets.
“a | b”
Set Intersection. Find intersection of two sets.
“a & b”
Set Complement. Given two sets A and B, find all elements in A that are not in B.
“a - b”
Set Symmetric Difference. Find symmetric difference of two sets.
“a ^ b”
Power Set. Generate all subsets of a set.
“power_set(a)”
Set Cartesian Product. Find A x B.
“product(a, b, ..)”
Disjoint Set Test. Test if two sets are disjoint.
“is_disjoint(a, b, ..)”
Empty Set Test. Test if a given set is empty.
“is_empty(a)”
Minimum. Find the smallest element of a set.
“max(a)”
Maximum. Find the largest element of a set.
“min(a)”

Examples

> setz ‘“foo” in a’ <(echo foo) 1 > setz ‘len(a)’ <(echo for bar garply) 3 > setz ‘a < b’ <(echo foo bar baz) <(echo foo bar) 0 > setz ‘max(a)’ <(echo 9001 10) 9001 > setz ‘is_disjoint(a, b, c)’ <(echo foo) <(echo bar) <(echo baz garply) 1 > setz ‘a | b’ <(echo foo) <(echo baz garply) garply foo baz > setz ‘product(a, b)’ <(echo foo bar) <(echo baz garply) foo, garply foo, baz bar, garply bar, baz > setz ‘power_set(a)’ <(echo foo bar garply) garply foo garply, foo bar garply, bar foo, bar garply, foo, bar
