Module Delimited

All readers defined below will raise if they encounter unparsable content.


module Header : sig .. end
module Row : sig .. end
type ('a, 'b) reader = ?strip:bool -> ?skip_lines:int -> ?on_parse_error:[
| `Raise
| `Handle of string Core.Std.Queue.t -> exn -> [
| `Continue
| `Finish
] -> header:'a -> 'b

If strip is true (default is false) then spaces will be stripped from the beginning and end of fields.

If skip_lines is given then that number of lines will be read and discarded from the top of the file or Reader.t given.

If on_parse_error is `Raise any lines that fail to parse will raise an exception. If `Handle is given the offending line will be passed to the function given, which may then indicate that processing should continue or finish.

module Csv : sig .. end
proper csv file parsing is different than general delimited file parsing and requires special handling code
module Positional : sig .. end
val of_reader : (Header.t, ?quote:char -> sep:char -> Async.Std.Reader.t -> Row.t Async.Std.Pipe.Reader.t) reader

of_reader ?quote ?strip ?skip_lines ~sep ~header r returns a row pipe based on data read from the provided reader. sep is used as the separator between fields, and is assumed to be escaped with \ unless quote is given.

val create_reader : (Header.t, ?quote:char -> sep:char -> string -> Row.t Async.Std.Pipe.Reader.t Async.Std.Deferred.t) reader

create_reader ?strip ?skip_lines ~header filename same as of_reader, but creates the reader for you
