create_hint_db local name st use_dn. st is a transparency state for unification using this db use_dn switches the use of the discrimination net for all hints and patterns.

A constr which is Hint'ed will be:

push_resolve_hyp hname htyp db. used to add an hypothesis to the local hint database; Never raises a user exception; If the hyp cannot be used as a Hint, it is not added.

val push_resolve_hyp : Environ.env -> Evd.evar_map -> Names.Id.t -> Hint_db.t -> Hint_db.t

Create a Hint database from the pairs (name, constr). Useful to take the current goal hypotheses as hints; Boolean tells if lemmas with evars are allowed

val make_local_hint_db : Environ.env -> Evd.evar_map -> ?ts:TransparentState.t -> bool -> Tactypes.delayed_open_constr list -> hint_db
val make_db_list : hint_db_name list -> hint_db list
val wrap_hint_warning : 'a Proofview.tactic -> 'a Proofview.tactic

Use around toplevel calls to hint-using tactics, to enable the tracking of non-imported hints. Any tactic calling run_hint must be wrapped this way.

val wrap_hint_warning_fun : Environ.env -> Evd.evar_map -> (Evd.evar_map -> 'a * Evd.evar_map) -> 'a * Evd.evar_map

Variant of the above for non-tactics

val hint_res_pf : ?with_evars:bool -> ?with_classes:bool -> ?flags:Unification.unify_flags -> hint -> unit Proofview.tactic
