Parameters

module T : TableFormat.TABLES

Signature

type state = int

val number : state -> int

type token = T.token

type terminal = int

type nonterminal = int

type semantic_value = Obj.t

val token2terminal : token -> terminal

val token2value : token -> semantic_value

val error_terminal : terminal

val error_value : semantic_value

val foreach_terminal : (terminal -> 'a -> 'a) -> 'a -> 'a

type production = int

val production_index : production -> int

val find_production : int -> production

val default_reduction : 
  state ->
  ('env -> production -> 'answer) ->
  ('env -> 'answer) ->
  'env ->
  'answer

val action : 
  state ->
  terminal ->
  semantic_value ->
  ('env -> bool -> terminal -> semantic_value -> state -> 'answer) ->
  ('env -> production -> 'answer) ->
  ('env -> 'answer) ->
  'env ->
  'answer

val maybe_shift_t : state -> terminal -> state option

maybe_shift_t s t determines whether there exists a transition out of the state s, labeled with the terminal symbol t, to some state s'. If so, it returns Some s'. Otherwise, it returns None.

val may_reduce_prod : state -> terminal -> production -> bool

may_reduce_prod s t prod determines whether in the state s, with lookahead symbol t, the automaton reduces production prod. This test accounts for the possible existence of a default reduction.

val goto_nt : state -> nonterminal -> state

val goto_prod : state -> production -> state

val maybe_goto_nt : state -> nonterminal -> state option

val lhs : production -> nonterminal

val is_start : production -> bool

exception Error
