Synopsis

Documentation

globSubsume :: LibName -> LibEnv -> LibEnv Source #

tries to apply global subsumption to all unproven global theorem edges

globDecompFromList :: LibName -> [LEdge DGLinkLab] -> LibEnv -> LibEnv Source #

applies global decomposition to the list of edges given (global theorem edges) if possible, if empty list is given then to all unproven global theorems. Notice: (for ticket 5, which solves the problem across library border) 1. before the actual global decomposition is applied, the whole DGraph is updated firstly by calling the function updateDGraph. 2. The changes of the update action should be added as the head of the history.
