Implementation of the Deflate algorithm in pure OCaml

Escalate

Pure OCaml data compression.

Rationale

zlib is a de-facto key library of the internet, as the DEFLATE compression and its container formats ZLIB and GZIP are ubiquitous. This library tries to supply a type-safe, memory safe alternative to zlib.

Format support

Parsing deflated files is currently in the works.

Inflate support	partly
Uncompressed	yes
Fixed Huffman	yes
Dynamic Huffman	no

Compressing is not yet implemented.

Deflate support	no
Uncompressed	no
Fixed Huffman	no
Dynamic Huffman	no

DEFLATE streams can be part of a number of containers. The most common ones are planned to be implemented.

Container support	partly
ZLIB	yes
GZIP	no
ZIP	no

Installation

You want to try it out? Cool, here are the the build instructions. At best you get your OCaml via OPAM. Eventually, once this library matures, it will also be available from OPAM directly!

If you want to build the code from the Git repository, you should follow my footsteps and use these commands:

opam install oasis bitstring ounit
oasis setup
ocaml setup.ml -configure
ocaml setup.ml -build

This will get you the compiled binaries.

License

The license of escalate is the same as of zlib, the so-called zlib license, for convenience reasons. If you can use zlib in your program, you can use escalate.
