This module provides a function to translate a signature to the XTC format used in the termination competition.

see http://cl2-informatik.uibk.ac.at/mercurial.cgi/TPDB/file/tip/xml/xtc.xsd

val print_sym : Core.Term.sym Lplib.Base.pp

print_sym ppf s outputs the fully qualified name of s to ppf. Modules are separated with ".".

type symb_status =

| Object_level
| Basic_type
| Type_cstr

val status : Core.Term.sym -> symb_status

status s returns Type_cstr if s has a type of the form T1 -> ... -> Tn -> TYPE with n > 0, Basic_type if s has type TYPE and Object_level otherwise.

val print_term : int -> string -> Core.Term.term Lplib.Base.pp

print_term ppf p outputs XTC format corresponding to the term t, to ppf.

val print_type : int -> string -> Core.Term.term Lplib.Base.pp

val print_rule : 
  Stdlib.Format.formatter ->
  int ->
  Core.Term.sym ->
  Core.Term.rule ->
  unit

print_rule ppf s r outputs the rule declaration corresponding r (on the symbol s), to ppf.

val print_tl_rule : 
  Stdlib.Format.formatter ->
  int ->
  Core.Term.sym ->
  Core.Term.rule ->
  unit

print_tl_rule is identical to print_rule but for type-level rule

val get_vars : 
  Core.Term.sym ->
  Core.Term.rule ->
  (string * Core.Term.term) list

get_vars s r returns the list of variables used in the rule r, in the form of a pair containing the name of the variable and its type, inferred by the solver.

val to_XTC : Stdlib.Format.formatter -> Core.Sign.t -> unit

to_XTC ppf sign outputs a XTC representation of the rewriting system of the signature sign to ppf.
