A number lower is higher priority

poly : bool;

Is the hint polymorpic and hence should be refreshed at each application

pat : Pattern.constr_pattern option;

A pattern for the concl of the Goal

name : hints_path_atom;

A potential name to refer to the hint

db : string option;

The database from which the hint comes

secvars : Names.Id.Pred.t;

The set of section variables the hint depends on

code : 'a;

the tactic to apply when the concl matches pat

This function is for backward compatibility only, not to use in newly written code.

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
