Constrexpr_ops: utilities on constr_expr

val sort_name_expr_eq : Constrexpr.sort_name_expr -> Constrexpr.sort_name_expr -> bool
val univ_level_expr_eq : Constrexpr.univ_level_expr -> Constrexpr.univ_level_expr -> bool
val sort_expr_eq : Constrexpr.sort_expr -> Constrexpr.sort_expr -> bool
val explicitation_eq : Constrexpr.explicitation -> Constrexpr.explicitation -> bool

Equality on explicitation.

val constr_expr_eq : Constrexpr.constr_expr -> Constrexpr.constr_expr -> bool

Equality on constr_expr. This is a syntactical one, which is oblivious to some parsing details, including locations.

Equality on local_binder_expr. Same properties as constr_expr_eq.

val binder_kind_eq : Constrexpr.binder_kind -> Constrexpr.binder_kind -> bool

Equality on binder_kind

Retrieving locations
val constr_loc : Constrexpr.constr_expr -> Loc.t option
val cases_pattern_expr_loc : Constrexpr.cases_pattern_expr -> Loc.t option
val local_binders_loc : Constrexpr.local_binder_expr list -> Loc.t option
Term constructors

Basic form of the corresponding constructors

Basic form of application, collapsing nested applications

Optimized constructors: does not add a constructor for an empty binder list

Aliases for the corresponding constructors; generally mkLambdaCN and mkProdCN should be preferred

Pattern constructors

Interpretation of a list of patterns as a disjunctive pattern (optimized)

Apply a list of pattern arguments to a pattern

val coerce_reference_to_id : Libnames.qualid -> Names.Id.t

FIXME: nothing to do here

val coerce_to_id : Constrexpr.constr_expr -> Names.lident

Destruct terms of the form CRef (Ident _).

val coerce_to_name : Constrexpr.constr_expr -> Names.lname

Destruct terms of the form CRef (Ident _) or CHole _.

val coerce_to_cases_pattern_expr : Constrexpr.constr_expr -> Constrexpr.cases_pattern_expr
Binder manipulation
val default_binder_kind : Constrexpr.binder_kind
val names_of_local_binders : Constrexpr.local_binder_expr list -> Names.lname list

Retrieve a list of binding names from a list of binders.

val names_of_local_assums : Constrexpr.local_binder_expr list -> Names.lname list

Same as names_of_local_binder_exprs, but does not take the let bindings into account.

Folds and maps
val fold_constr_expr_with_binders : (Names.Id.t -> 'a -> 'a) -> ('a -> 'b -> Constrexpr.constr_expr -> 'b) -> 'a -> 'b -> Constrexpr.constr_expr -> 'b

Used in typeclasses

Used in correctness and interface; absence of var capture not guaranteed in pattern-matching clauses and in binders of the form x,y:T(x)

val map_constr_expr_with_binders : (Names.Id.t -> 'a -> 'a) -> ('a -> Constrexpr.constr_expr -> Constrexpr.constr_expr) -> 'a -> Constrexpr.constr_expr -> Constrexpr.constr_expr
val free_vars_of_constr_expr : Constrexpr.constr_expr -> Names.Id.Set.t
val occur_var_constr_expr : Names.Id.t -> Constrexpr.constr_expr -> bool
val names_of_constr_expr : Constrexpr.constr_expr -> Names.Id.Set.t

Return all (non-qualified) names treating binders as names

val ntn_loc : ?loc:Loc.t -> Constrexpr.constr_notation_substitution -> Constrexpr.notation -> (int * int) list
val patntn_loc : ?loc:Loc.t -> Constrexpr.cases_pattern_notation_substitution -> Constrexpr.notation -> (int * int) list
val error_invalid_pattern_notation : ?loc:Loc.t -> unit -> 'a

For cases pattern parsing errors
