Add table format parameter to show table recursion

[o-lim]

This adds the TableFormatShowRecursion parameter to enable showing of table recursion when a table is formatted for display. This parameter is set to false by default.

  it("Test recursive table - show recursion", function()
    local t = {1,2}
    t[3] = t
    assert:set_parameter("TableFormatShowRecursion", true)
    assert.is.equal({}, t)
  end)

Failure → spec/test_spec.lua @ 1
Test recursive table - show recursion
spec/test_spec.lua:5: Expected objects to be equal.
Passed in:
(table) {
  [1] = 1
  [2] = 2
  [3] = { ... recursive } }
Expected:
(table) { }

  it("Test recursive table - no show recursion", function()
    local t = {1,2}
    t[3] = t
    assert:set_parameter("TableFormatShowRecursion", false)  -- this is the default value
    assert.is.equal({}, t)
