Project Description

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
