Positional parses fixed-width fields.

module Row = Delimited_kernel.Read.Row

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

type header = (string * int * int) list

Specify the name, and 0-based starting position and length of each column. For example column 'foo' starting on the first character of each line and 8 characters wide would be ("foo", 0, 8). Column ranges must not overlap.

All following funtions return Error if column ranges overlap.

val of_reader : 
  (header,
    ?strict:bool ->
    Async.Reader.t ->
    Row.t Async.Pipe.Reader.t Core.Or_error.t)
    Shared.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.

  (header,
    ?strict:bool ->
    string ->
    Row.t Async.Pipe.Reader.t Async.Deferred.Or_error.t)
    Shared.reader
