}Representation of the proof state of a theorem.
val finished : proof_state -> boolfinished ps tells whether there are unsolved goals in ps.
val goals : proof_state Lplib.Base.ppgoals ppf gl prints the goal list gl to channel ppf.
val remove_solved_goals : proof_state -> proof_stateremove_solved_goals ps removes from the proof state ps the typing goals that are solved.
val meta_of_key : proof_state -> int -> Core.Term.meta optionmeta_of_key ps i returns Some m where m is a meta of ps whose key is i, or else it returns None.
val focus_env : proof_state option -> Core.Env.tfocus_env ps returns the scoping environment of the focused goal or the empty environment if there is none.
