/p7zip-ciel

A new p7zip fork with additional codecs and improvements (forked from https://sourceforge.net/projects/p7zip/).

Primary LanguageC++

Retrying to contact jinfeihan57 by https://github.com/jinfeihan57/p7zip/issues/179#issuecomment-1294270250 , let's see how it will go...

This repository's goal was these:

  • to provide automated p7zip binary generator for Windows / macOS (x86-64/arm64) / Linux / Android
  • to provide standalone Codecs plugin for PKImplode / BALZ / BCM

These goals have been already acheived. You can put Codecs directory to the same directory as 7z.so/dll (from official 7-zip or jinfeihan57/p7zip).

I'd like to have these patch merged into jinfeihan57/p7zip, but I had issue in resolving conflict, so I have given up.

Excuse: to utilize git's 3-way merge, I have suggested https://github.com/jinfeihan57/p7zip/issues/179 , but it was not adopted.

This repo has been archived (might be temporary unarchived when I got interested but it will happen rarely).

Refer https://github.com/cielavenir/p7zip/blob/main/.github/workflows/ci.yaml for building manually.

7zz with extension method

This is the place for 7zz (Well known as 7zip-22.01 Linux version) to include major modern codecs such as Brotli, Fast LZMA2, LZ4, LZ5, Lizard and Zstd. In order to support multithreading for those addional codecs, this project depends on the Multithreading Library.

Codec overview

  1. Zstandard v1.5.2 is a real-time compression algorithm, providing high compression ratios. It offers a very wide range of compression / speed trade-off, while being backed by a very fast decoder.

    • Levels: 1..22

  2. LZ4 v1.9.4 is lossless compression algorithm, providing compression speed at 400 MB/s per core (0.16 Bytes/cycle). It features an extremely fast decoder, with speed in multiple GB/s per core (0.71 Bytes/cycle). A high compression derivative, called LZ4_HC, is available, trading customizable CPU time for compression ratio.

    • Levels: 1..12

  3. Fast LZMA2 v1.0.1 is a LZMA2 compression algorithm, 20% to 100% faster than normal LZMA2 at levels 5 and above, but with a slightly lower compression ratio. It uses a parallel buffered radix matchfinder and some optimizations from Zstandard. The codec uses much less additional memory per thread than standard LZMA2.

    • Levels: 1..9

  4. Brotli v1.0.9 is a generic-purpose lossless compression algorithm that compresses data using a combination of a modern variant of the LZ77 algorithm, Huffman coding and 2nd order context modeling, with a compression ratio comparable to the best currently available general-purpose compression methods. It is similar in speed with deflate but offers more dense compression.

    • Levels: 0..11

  5. LZ5 v1.5 is a modification of LZ4 which gives a better ratio at cost of slower compression and decompression.

    • Levels: 1..15

  6. Lizard v1.0 is an efficient compressor with very fast decompression. It achieves compression ratio that is comparable to zip/zlib and zstd/brotli (at low and medium compression levels) at decompression speed of 1000 MB/s and faster.

    • Levels 10..19 (fastLZ4) are designed to give about 10% better decompression speed than LZ4
    • Levels 20..29 (LIZv1) are designed to give better ratio than LZ4 keeping 75% decompression speed
    • Levels 30..39 (fastLZ4 + Huffman) adds Huffman coding to fastLZ4
    • Levels 40..49 (LIZv1 + Huffman) give the best ratio, comparable to zlib and low levels of zstd/brotli, but with a faster decompression speed

  7. [Lzham] v1.1 is a lossless data compression codec written in C/C++ (specifically C++03), with a compression ratio similar to LZMA but with 1.5x-8x faster decompression speed.

    • Levels: 1..9
    • Level: 1 best speed
    • Level: 9 best compression
    • Level: 10 best with extreme parsing (can be very slow) NOT RECOMMEND

  8. PKImplode is LZ variant used in PKZIP. Implementation adopted from StormLib 9.24.

  9. BALZ is ROLZ based compressor.

  10. BCM v1.60 is BWT+CM based compressor.

Build Binary

(Currently only supports CLI, if you want to do GUI please contact us)

  1. Download src:
   git clone -b 7zip_21.02 https://github.com/jinfeihan57/p7zip.git
  1. Use makefile to compile and build the binary 7zz:
   cd p7zip/CPP/7zip/Bundles/Alone2 && make -f makefile.gcc
   OR
   cd p7zip/CPP/7zip/Bundles/Alone2 && make -j -f ../../cmpl_gcc.mak

If you want build 7za:

   cd p7zip/CPP/7zip/Bundles/Alone && make -f makefile.gcc
   OR
   cd p7zip/CPP/7zip/Bundles/Alone && make -j -f ../../cmpl_gcc.mak

7zr:

   cd p7zip/CPP/7zip/Bundles/Alone7z && make -f makefile.gcc
   OR
   cd p7zip/CPP/7zip/Bundles/Alone7z && make -j -f ../../cmpl_gcc.mak

or build 7z.so:

   cd p7zip/CPP/7zip/Bundles/Format7zF && make -f makefile.gcc
   OR
   cd p7zip/CPP/7zip/Bundles/Format7zF && make -j -f ../../cmpl_gcc.mak
  1. Test:
   ./_o/7zz i
  1. The output should look like this:
XXX@ubuntu:~/github/p7zip/CPP/7zip/Bundles/Alone2$ ./_o/7zz i
