Printing/Parsing

type parse_cache

Cache that remembers the set of files that have been parsed so far

val create_parse_cache : unit -> parse_cache

val find_file : string -> string -> string option

find_file name dir looks for a file with the given name, recursively, in dir, or in its parent dir recursively. It also looks in the "TPTP" environment variable.

val parse_lexbuf : 
  ?names:A.name list ->
  Lexing.lexbuf ->
  untyped A.t Iter.t or_error

Given a lexbuf, try to parse its content into a sequence of untyped declarations

val parse_file : 
  ?cache:parse_cache ->
  recursive:bool ->
  string ->
  untyped A.t Iter.t or_error

Parsing a TPTP file is here presented with a recursive option that, if true, will make "include" directives to be recursively parsed. It uses find_file for included files.

parameter parse_cache
used to avoid including the same file twice, if recursive=true

returns
an error-wrapped sequence of declarations.

Printing is simpler, because it does not involve includes.

val print_into : 't CCFormat.printer -> 't A.t Iter.t CCFormat.printer

val print_into_file : 't CCFormat.printer -> string -> 't A.t Iter.t -> unit

val has_includes : _ A.t Iter.t -> bool

Check whether some include declaration can be found in the sequence

Bridge to UntypedAST

val to_ast : untyped A.t -> Logtk.UntypedAST.statement

raises Error
if there are remaining includes

val of_ast : Logtk.UntypedAST.statement -> untyped A.t

raises Error
if the AST contains Data
