Module `Tacred`

type evaluable_global_reference = | EvalVarRef of Names.Id.t | EvalConstRef of Names.Constant.t

val eq_egr : evaluable_global_reference -> evaluable_global_reference -> bool
val subst_evaluable_reference : Mod_subst.substitution -> evaluable_global_reference -> evaluable_global_reference: Here the semantics is completely unclear. What does "Hint Unfold t" means when "t" is a parameter? Does the user mean "Unfold X.t" or does she mean "Unfold y" where X.t is later on instantiated with y? I choose the first interpretation (i.e. an evaluable reference is never expanded).

type reduction_tactic_error = | InvalidAbstraction of Environ.env * Evd.evar_map * EConstr.constr * Environ.env * Type_errors.type_error

val error_not_evaluable : Names.GlobRef.t -> 'a
val evaluable_of_global_reference : Environ.env -> Names.GlobRef.t -> evaluable_global_reference
val global_of_evaluable_reference : evaluable_global_reference -> Names.GlobRef.t
val red_product : Environ.env -> Evd.evar_map -> EConstr.constr -> EConstr.constr option: Red (returns None if nothing reducible)

val hnf_constr : Reductionops.reduction_function: Hnf: like whd_simpl but force delta-reduction of constants that do not immediately hide a non reducible fix or cofix

val hnf_constr0 : Reductionops.reduction_function: Variant of the above that does not perform nf-βι

val unfoldn : (Locus.occurrences * evaluable_global_reference) list -> Reductionops.reduction_function: Unfold

val fold_commands : EConstr.constr list -> Reductionops.reduction_function: Fold

val pattern_occs : (Locus.occurrences * EConstr.constr) list -> Reductionops.e_reduction_function: Pattern

val cbv_norm_flags : RedFlags.reds -> strong:bool -> Reductionops.reduction_function: Call by value strategy (uses Closures)

val reduce_to_atomic_ind : Environ.env -> Evd.evar_map -> EConstr.types -> (Names.inductive * EConstr.EInstance.t) * EConstr.types: reduce_to_atomic_ind env sigma t puts t in the form t'=(I args) with I an inductive definition; returns I and t' or fails with a user error

val reduce_to_quantified_ind : Environ.env -> Evd.evar_map -> EConstr.types -> (Names.inductive * EConstr.EInstance.t) * EConstr.types: reduce_to_quantified_ind env sigma t puts t in the form t'=(x1:A1)..(xn:An)(I args) with I an inductive definition; returns I and t' or fails with a user error

val eval_to_quantified_ind : Environ.env -> Evd.evar_map -> EConstr.types -> Names.inductive * EConstr.EInstance.t: Same as reduce_to_quantified_ind but more efficient because it does not return the normalized type.

val reduce_to_quantified_ref : ?⁠allow_failure:bool -> Environ.env -> Evd.evar_map -> Names.GlobRef.t -> EConstr.types -> EConstr.types: reduce_to_quantified_ref env sigma ref t try to put t in the form t'=(x1:A1)..(xn:An)(ref args). When this is not possible, if allow_failure is specified, t is unfolded until the point where this impossibility is plainly visible. Otherwise, it fails with user error.

val reduce_to_atomic_ref : ?⁠allow_failure:bool -> Environ.env -> Evd.evar_map -> Names.GlobRef.t -> EConstr.types -> EConstr.types
val find_hnf_rectype : Environ.env -> Evd.evar_map -> EConstr.types -> (Names.inductive * EConstr.EInstance.t) * EConstr.constr list
val contextually : bool -> (Locus.occurrences * Pattern.constr_pattern) -> (Ltac_pretype.patvar_map -> Reductionops.reduction_function) -> Reductionops.reduction_function
val e_contextually : bool -> (Locus.occurrences * Pattern.constr_pattern) -> (Ltac_pretype.patvar_map -> Reductionops.e_reduction_function) -> Reductionops.e_reduction_function
val check_privacy : Environ.env -> Names.inductive -> unit: Errors if the inductive is not allowed for pattern-matching. *
