innoextract allows extracting Inno Setup installers under non-Windows systems without running the actual installer using wine.

Pbzip2 is a parallel implementation of the bzip2 block-sorting file compressor that uses pthreads and achieves near-linear speedup on SMP machines. The output of this version is fully compatible with bzip2 v1.0.2 (i.e. anything compressed with pbzip2 can be decompressed with bzip2).

Blosc is a high performance compressor optimized for binary data. It has been designed to transmit data to the processor cache faster than the traditional, non-compressed, direct memory fetch approach via a memcpy() system call. Blosc is meant not only to reduce the size of large datasets on-disk or in-memory, but also to accelerate memory-bound computations.

Parallel Zstandard (PZstandard or pzstd) is a multi-threaded implementation of the Zstandard compression algorithm. It is fully compatible with the original Zstandard file format and command-line interface, and can be used as a drop-in replacement.

Compression is distributed over multiple processor cores to improve performance, as is the decompression of data compressed in this manner. Data compressed by other implementations will only be decompressed by two threads: one performing the actual decompression, the other input and output.

7-zip is a command-line file compressor that supports a number of archive formats and features self-extracting archives.

Lzip is a lossless data compressor with a user interface similar to the one of gzip or bzip2. Lzip decompresses almost as fast as gzip and compresses more than bzip2, which makes it well-suited for software distribution and data archiving. Lzip is a clean implementation of the LZMA algorithm.

Lunzip is a decompressor for files in the lzip compression format (.lz), written as a single small C tool with no dependencies. This makes it well-suited to embedded and other systems without a C++ compiler, or for use in applications such as software installers that need only to decompress files, not compress them. Lunzip is intended to be fully compatible with the regular lzip package.

Zip is a compression and file packaging/archive utility. Zip is useful for packaging a set of files for distribution, for archiving files, and for saving disk space by temporarily compressing unused files or directories. Zip puts one or more compressed files into a single ZIP archive, along with information about the files (name, path, date, time of last modification, protection, and check information to verify file integrity). An entire directory structure can be packed into a ZIP archive with a single command.

Zip has one compression method (deflation) and can also store files without compression. Zip automatically chooses the better of the two for each file. Compression ratios of 2:1 to 3:1 are common for text files.

UCL implements a number of compression algorithms that achieve an excellent compression ratio while allowing fast decompression. Decompression requires no additional memory.

Compared to LZO, the UCL algorithms achieve a better compression ratio but decompression is a little bit slower.

minizip-ng is a zip manipulation library written in C, forked from the zip manipulation library found in the zlib distribution.

Minizip is a minimalistic library that supports compressing, extracting and viewing ZIP archives. This version is extracted from the zlib source.

Miniz is a lossless data compression library that implements the zlib (RFC 1950) and Deflate (RFC 1951) compressed data format specification standards. It supports the most commonly used functions exported by the zlib library.

gzstream is a small library for providing zlib functionality in a C++ iostream.

Lziprecover is a data recovery tool and decompressor for files in the lzip compressed data format (.lz). It can test the integrity of lzip files, extract data from damaged ones, and repair most files with small errors (up to one single-byte error per member) entirely.

Lziprecover is not a replacement for regular backups, but a last line of defence when even the backups are corrupt. It can recover files by merging the good parts of two or more damaged copies, such as can be easily produced by running ddrescue on a failing device.

This package also includes unzcrash, a tool to test the robustness of decompressors when faced with corrupted input.

A data compression/decompression library for embedded/real-time systems.

Among its features are:

• Low memory usage (as low as 50 bytes.) It is useful for some cases with less than 50 bytes, and useful for many general cases with less than 300 bytes.

• Incremental, bounded CPU use. It can be used to chew on input data in arbitrarily tiny bites. This is a useful property in hard real-time environments.

• Can use either static or dynamic memory allocation.

Zstandard (zstd) is a lossless compression algorithm that combines very fast operation with a compression ratio comparable to that of zlib. In most scenarios, both compression and decompression can be performed in ‘real time’. The compressor can be configured to provide the most suitable trade-off between compression ratio and speed, without affecting decompression speed.

CBOR is a data format whose design goals include the possibility of extremely small code size, fairly small message size, and extensibility without the need for version negotiation. These design goals make it different from earlier binary serializations such as ASN.1 and MessagePack.

LZFSE is a Lempel-Ziv style data compression algorithm using Finite State Entropy coding. It targets similar compression rates at higher compression and decompression speed compared to Deflate using Zlib.

QuaZIP is a simple C++ wrapper over Gilles Vollant's ZIP/UNZIP package that can be used to access ZIP archives. It uses Trolltech's Qt toolkit.

QuaZIP allows you to access files inside ZIP archives using QIODevice API, and that means that you can also use QTextStream, QDataStream or whatever you would like to use on your zipped files.

QuaZIP provides complete abstraction of the ZIP/UNZIP API, for both reading from and writing to ZIP archives.

SfArkLib is a C++ library for decompressing SoundFont files compressed with the sfArk algorithm.

FastJar is an attempt to create a much faster replacement for Sun's jar utility. Instead of being written in Java, FastJar is written in C.

Compton is a compositor for the Xorg display server and a for of xcompmgr-dana, which implements some changes like:

• OpenGL backend (--backend glx), in addition to the old X Render backend.

• Inactive window transparency (-i) and dimming (--inactive-dim).

• Menu transparency (-m, thanks to Dana).

• Shadows are now enabled for argb windows, e.g terminals with transparency

• Removed serverside shadows (and simple compositing) to clean the code, the only option that remains is clientside shadows.

• Configuration files (see the man page for more details).

• Colored shadows (--shadow-[red/green/blue]).

• A new fade system.

• VSync support (not always working).

• Blur of background of transparent windows, window color inversion (bad in performance).

• Some more options...

Picom is a standalone compositor for Xorg, suitable for use with window managers that do not provide compositing.

Picom is a fork of compton, which is a fork of xcompmgr-dana, which in turn is a fork of xcompmgr.

Konsave is CLI that lets you backup your dotfiles and switch to other ones. Features:

• storing configurations in profiles

• exporting profiles to '.knsv' files

• import profiles from '.knsv' files

• official support for KDE Plasma
