Utilities for reading input one line at a time. The basic idea is that different types of input which can be read one line at a time can all be converted into a string Seq.t. Then any further manipulations / operations on this input can be done in a uniform way by operating on those.
type t = string Seq.tval of_channel : in_channel -> tRead data from a channel one line at a time. I.e this is like using the input_line funtion from Stdlib and the creating a Seq of the results, until the end of the input is reached.
val of_string : string -> tSplit string into lines
type 'a loader = string -> t -> 'aA 'a loarder converts input into a value of type 'a. It is given the first line of input as its first argument, and any additional lines can be read from the second parameter as needed. (This mechanic allows a one line lookahead for making decisions about how to parse data.
load_list terminator item_loader produces a line-based loader which reads in a list of items by using item_loader to load one item, until the input matches an expected terminator string.
val load_line : string loaderA loader that loads a single line of input and returns that as its result
