ShowSet

Build Status

This module makes the printing of Set objects in Julia nicer.

Usage

Without the use of this module, Set objects display like this:

julia> BitSet([1,3,0])
BitSet([1,3,0])

julia> Set(["One", "Two", "Three"])
Set("One","Two","Three")

However, after using ShowSet it looks like this:

julia> BitSet([1,3,0])
{0,1,3}

julia> Set(["One", "Two", "Three"])
{One,Three,Two}

The elements of the Set object are sorted into ascending order unless Julia is unable to do so. In that case, the order of the objects is arbitrary.

julia> Set([1, "hello", 4.5, 2+3im])
{hello,2 + 3im,4.5,1}

Representing the empty set

By default, this module renders the empty set as Ø (LaTeX \O). This behavior can be changed with the set_empty function.

julia> A = Set()
Ø
julia> set_empty("{}");

julia> A
{}

Conversion to string

We extend the string function for Set and BitSet objects to provide for their conversion into String objects. Some examples:

julia> A = Set(["alpha", "beta", "gamma"]);

julia> string(A)
"{alpha,beta,gamma}"

julia> B = BitSet([5,3,1]);

julia> string(B)
"{1,3,5}"

julia> typeof(ans)
String
