Module SequenceLabels.IO

val lines_of : ?⁠mode:int -> ?⁠flags:Pervasives.open_flag list -> string -> string t

lines_of filename reads all lines of the given file. It raises the same exception as would opening the file and read from it, except from End_of_file (which is caught). The file is always properly closed. Every time the sequence is iterated on, the file is opened again, so different iterations might return different results

parameter mode

default 0o644

parameter flags

default: [Open_rdonly]

val chunks_of : ?⁠mode:int -> ?⁠flags:Pervasives.open_flag list -> ?⁠size:int -> string -> string t

Read chunks of the given size from the file. The last chunk might be smaller. Behaves like lines_of regarding errors and options. Every time the sequence is iterated on, the file is opened again, so different iterations might return different results

val write_to : ?⁠mode:int -> ?⁠flags:Pervasives.open_flag list -> string -> string t -> unit

write_to filename seq writes all strings from seq into the given file. It takes care of opening and closing the file.

parameter mode

default 0o644

parameter flags

used by open_out_gen. Default: [Open_creat;Open_wronly].

val write_lines : ?⁠mode:int -> ?⁠flags:Pervasives.open_flag list -> string -> string t -> unit

Same as write_to, but intercales '\n' between each string
