Module Logtk.UntypedAST

Main AST before Typing

module Loc = ParseLocation
module T = STerm
type term = T.t
type ty = T.t
type form = T.t
type data = {
data_name : string;
data_vars : string list;
data_cstors : (string * (string option * ty) list) list;
}

Basic definition of inductive types

type attr =
| A_app of string * attr list
| A_quoted of string
| A_list of attr list

Attributes (general terms)

type attrs = attr list
type def = {
def_id : string;
def_ty : ty;
def_rules : term list;
}
type statement_view =
| Include of string
| Decl of string * ty
| Def of def list
| Rewrite of term
| Data of data list
| Assert of form
| Lemma of form
| Goal of form

Statement

type statement = {
stmt : statement_view;
attrs : attrs;
loc : Loc.t option;
}
