Printing/Parsing

Sourcetype parse_cache

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

Sourceval create_parse_cache : unit -> parse_cache
Sourceval 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.

Sourceval 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

Sourceval 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.

Sourceval print_into : 't CCFormat.printer -> 't A.t Iter.t CCFormat.printer
Sourceval print_into_file : 't CCFormat.printer -> string -> 't A.t Iter.t -> unit
Sourceval has_includes : _ A.t Iter.t -> bool

Check whether some include declaration can be found in the sequence

Bridge to UntypedAST

  • raises Error

    if there are remaining includes

  • raises Error

    if the AST contains Data
