Sourceval syms : string Core.Term.SymMap.t ref

syms maps every symbol to a name.

bvars is the set of abstracted variables.

Sourceval nb_rules : int ref

nb_rules is the number of rewrite rules.

Sourceval pvars : (int * int * Core.Term.term) list ref

pvars is the list of all pattern variables with their type.

Sourceval type_of_pvar : Core.Term.term array ref

typ is a reference to the types of the pvars of the current rules.

sym_name s translates the symbol name of s.

Sourceval add_sym : Core.Term.sym -> unit

add_sym declares a Lambdapi symbol.

type_sym ppf s translates the Lambdapi type symbol s.

sym ppf s translates the Lambdapi symbol s.

Sourceval add_bvar : Core.Term.tvar -> unit

add_bvar v declares an abstracted Lambdapi variable.

bvar v translates the Lambdapi bound variable v.

Sourceval pvar : int Lplib.Base.pp

pvar i translates the Lambdapi pattern variable i.

term ppf t translates the term t.

Sourceval pvar_app : (int * Core.Term.term array) Lplib.Base.pp
Sourceval add_pvars : Core.Term.sym -> Core.Term.rule -> unit

add_pvars s r adds the types of the pvars of r in pvars.

rule ppf r translates the pair of terms r as a rule.

sym_rule ppf s r increases the number of rules and translates the sym_rule r.

Translate the rules of symbol s.

Sourceval rules_of_sign : Core.Sign.t Lplib.Base.pp

Translate the rules of a dependency except if it is a ghost signature.

sign ppf s translates the Lambdapi signature s.
