Pure OCaml implementation of Zlib

Decompress is a pure implementation of zlib. The goal is to create an available package for Mirage OS for zlib in OCaml (instead a C code).

We respect the interface of zlib and all flush mode is available (experimental):

• SYNC_FLUSH
• PARTIAL_FLUSH
• FULL_FLUSH

The interface proposed is a non-blocking interface.

Installation

Decompress can be installed with opam:

opam install decompress

Sample programs

Sample program are located in the bin directory of the distribution. It can be built with (dependancy with Unix module, the cmdliner package and a C code):

ocamlbuild -use-ocamlfind bin/dpipe.native

Another good example is provided in bin/easy.ml with the signature:

val compress   : ?level:int -> string -> string
val uncompress : string -> string

And you can compile this program with:

ocamlbuild -use-ocamlfind bin/easy.native

But keep in your mind, it's an easy example and it's not optimized for a productive environment - so, don't copy/paste and think.

The documentation is available online to understand how to use Decompress.

Build Requirements

• OCaml >= 4.02.0
• base-bytes meta-package
• Bigarray module (provided by the standard library of OCaml)
• topkg, ocamlfind and ocamlbuild to build the project

If you want to compile the test program, you need:

• camlzip to compare decompress with zlib
• re
• alcotest
