Proof Skeleton View

Purpose

The Proof Skeleton View gives the user the ability to quickly browse the skeleton of a proof, without having to prove it anew. Furthermore, it is intended to be a convenient way to display rules and sequents together in the same view.

The Proof Skeleton View

Showing the View

The Proof Skeleton View is available as other views in the Window > Show View > Other > Event-B > Proof Skeleton View menu.

To watch a proof skeleton, simply select a proved predicate in the obligation explorer, or a proof file in the editor.

View Interpretation

Proof skeletons are displayed in a two-part view. On the left hand side is the tree structure of rules applied in the proof. On the other side stands the sequent on which the currently selected rule is applied.

The tree can be expanded or collapsed by using [+] and [-] buttons on the upper right corner.
