:'''Project Explorer's Actions now able to run in background'''. The "Proof Replay on Undischarged POs", "Retry Auto Provers" and "Recalculate Auto Status" commands are now able to run in background. The user is allowed to modify his models, and do interactive proving while such commands are running. Note that the "save" action on interactively proved PO which is concerned by such command, might be delayed as concurrency occurs. The "save" action will be then be scheduled as a further task to perform, and the user will have to wait or cancel the command. Those commands are accessible by a right-click in the Event-B Explorer.

:'''A new mechanism to collect informations while traversing formulae'''. IFormulaInspector<F> interface has been added and published in order to ease the aggregation of informations (of type F) computed while traversing the AST of a formula. This mechanism replace the old one, where one should retrieve positions where such informations could take place and iterate in a second time on each positions to calculate and accumulate informations.

Overview

The Proving Perspective is made of a number of windows (views): the Proof Tree, the Goal, the Selected Hypotheses, the Proof Control, the Proof Information, and the Search Hypotheses. In subsequent sections, we study each of these windows. Below is a screenshot of the proving perspective:

Loading a Proof

In order to load a proof, enter the Proof Obligation window, select the project, select and expand the component, finally select the proof obligation: the corresponding proof will be loaded. As a consequence:

  • the proof tree is loaded in the Proof Tree window. As we shall see in section 6.2, each node of the proof tree is associated with a sequent.
  • In case the proof tree has some "pending" nodes (whose sequents are not discharged yet) then the sequent corresponding to the first pending node is decomposed: its goal is loaded in the Goal window (section 6.3), whereas parts of its hypotheses (the "selected" ones) are loaded in the Selected Hypotheses window (section 6.3).
  • In case the proof tree has no pending node, then the sequent of the root node is loaded as explained previously.
