Module Parsexp__.Parser_automaton

include module type of Parsexp__.Parser_automaton_internal.Public
type ('user_state, 'stack) state

Internal state of the automaton

type ('u, 's) mode =
| Single

Parse a single s-expression

| Many

Parse a list of s-expressions

| Eager of {
got_sexp : ('u, 's) state -> 's -> 's;

Whether to consider no s-expression in the input as an error or not.

The mutability is used in Parsexp.Eager*.Lexbuf_consumer.

mutable no_sexp_is_error : bool;
}

Gives back s-expressions as soon as they are found.
