solve (SelectNth n) tac applies tactic tac to the nth subgoal of the current focused proof. solve SelectAll tac applies tac to all subgoals.

val solve : ?with_end_tac:unit Proofview.tactic -> Goal_select.t -> int option -> unit Proofview.tactic -> t -> t * bool
val use_unification_heuristics : unit -> bool

Option telling if unification heuristics should be used.

val refine_by_tactic : name:Names.Id.t -> poly:bool -> Environ.env -> Evd.evar_map -> EConstr.types -> unit Proofview.tactic -> Constr.constr * Evd.evar_map

A variant of the above function that handles open terms as well. Caveat: all effects are purged in the returned term at the end, but other evars solved by side-effects are NOT purged, so that unexpected failures may occur. Ideally all code using this function should be rewritten in the monad.

Helpers to obtain proof state when in an interactive proof

val get_proof_context : t -> Evd.evar_map * Environ.env

get_proof_context () gets the goal context for the first subgoal of the proof
