A wrapper of Jane Street's Stdio.In_channel. Add's peek_char and peek_line functions that work on fifos as well as regular files.

Used internally for bio input channels so that you can pipe directly from gzip even in channels that need peeking.

Differences from Stdio.In_channel

Some functions are not implemented.

type t

include Ppx_compare_lib.Equal.S with type t := t

val equal : t -> t -> bool

val stdin : t

val create : Base.string -> t

val close : t -> Base.unit

val with_file : Base.string -> f:(t -> 'a) -> 'a

val input_all : t -> Base.string

val input_line : ?fix_win_eol:Base.bool -> t -> Base.string Base.option

val input_line_exn : ?fix_win_eol:Base.bool -> t -> Base.string

val fold_lines : 
  ?fix_win_eol:Base.bool ->
  t ->
  init:'a ->
  f:('a -> Base.string -> 'a) ->
  'a

val input_lines : ?fix_win_eol:Base.bool -> t -> Base.string Base.list

val iter_lines : 
  ?fix_win_eol:Base.bool ->
  t ->
  f:(Base.string -> Base.unit) ->
  Base.unit

val read_lines : ?fix_win_eol:Base.bool -> Base.string -> Base.string Base.list

val read_all : Base.string -> Base.string

Both peek functions are safe to call in the context of one of the iterator functions.

val peek_char : ?fix_win_eol:Base.bool -> t -> Base.char Base.option

val peek_line : ?fix_win_eol:Base.bool -> t -> Base.string Base.option
