tar -- decode and encode tar files

tar is a simple library to read and write tar files with an emphasis on streaming.

This is pure OCaml code, no C bindings.

Installation

tar can be installed with opam:

opam install tar
opam install tar-unix    # for use in Unix/Lwt
opam install tar-mirage  # for use in MirageOS

If you don't use opam consult the tar.opam file for build instructions.

Example toplevel session

In utop:

utop # #require "tar";;
utop # #require "tar-unix";;

utop # let f = Lwt_unix.openfile "/tmp/foo.tar" [ Unix.O_RDONLY ] 0;;
val f : Lwt_unix.file_descr = <abstr>

utop # Lwt.bind f Tar_lwt_unix.Archive.list;;
[{Tar.Header.file_name = "_build/lib/tar.mli.depends";
  Tar.Header.file_mode = 420; Tar.Header.user_id = 1000;
  Tar.Header.group_id = 1000; Tar.Header.file_size = 21L;
  Tar.Header.mod_time = 1381080315L;
  Tar.Header.link_indicator = Tar.Header.Link.Normal;
  Tar.Header.link_name = ""};
 {Tar.Header.file_name = "_build/lib/tar_unix.mli.depends";
  Tar.Header.file_mode = 420; Tar.Header.user_id = 1000;
  Tar.Header.group_id = 1000; Tar.Header.file_size = 27L;
  Tar.Header.mod_time = 1381080318L;
  Tar.Header.link_indicator = Tar.Header.Link.Normal;
  Tar.Header.link_name = ""};
 {Tar.Header.file_name = "_build/lib/tar.mllib";
  Tar.Header.file_mode = ...; Tar.Header.user_id = ...;
  Tar.Header.group_id = ...; Tar.Header.file_size = ...;
  Tar.Header.mod_time = ...; Tar.Header.link_indicator = ...;
  Tar.Header.link_name = ...};
 ...]
