peek'(ZZ,Thing) -- examine contents of an object

Synopsis

Usage:
peek'(n,s)
Function: peek'
Inputs:
- n, an integer
- s, a thing
Outputs:
- a net, a net that displays the contents of s, bypassing installed formatting and printing methods to depth n

Description

i1 : s = factor 112

      4
o1 = 2 7

o1 : Expression of class Product

i2 : peek s

              4
o2 = Product{2 , 7}

i3 : peek'_2 s

o3 = Product{Power{2, 4}, Power{7, 1}}

Some types of things have the notion of depth modified slightly to make the entire structure visible at depth 1, as in the following example, which also shows how to use wrap with the output from peek.
