XZ examples for Delphi


This repository aims to provide Delphi bindings for liblzma and a translation of \doc\examples\ from XZ Utils package to Delphi. This Delphi code is licensed under LGPL3.

It should work with almost all versions of Delphi and even with Lazarus/FreePascal. However, pay attention to older versions of Delphi : the ErrOutput variable is not defined.

Currently, I do not care of linux compatibility because I had troubles with command line FreePascal compiler and when generating Makefile.

Any suggestions or improvements are welcome. Send them to


About XZ utils and liblzma

liblzma is a public domain general-purpose data compression library with a zlib-like API. The native file format is .xz, but also the old .lzma format and raw (no headers) streams are supported. Multiple compression algorithms (filters) are supported. Currently LZMA2 is the primary filter.

liblzma is part of XZ Utils. XZ Utils includes a gzip-like command line tool named xz and some other tools. XZ Utils is developed and maintained by Lasse Collin.

Major parts of liblzma are based on Igor Pavlov's public domain LZMA SDK. The SHA-256 implementation is based on the public domain code found from 7-Zip, which has a modified version of the public domain SHA-256 code found from Crypto++. The SHA-256 code in Crypto++ was written by Kevin Springle and Wei Dai.
