dhondta/recursive-compression

Tinyscript tool for recursively (de)compressing nested archives using multiple algorithms (bzip2, rar, lzma, ...)

Introduction

This tool relies on Tinyscript and allows to recursively (de)compress nested archives according to various decompression algorithms implemented in Patool.

Installation

$ pip install recursive-compression

Quick Start

Compression

$ rec-comp -h
usage: rec-comp [-c CHARSET] [-d] [-n NCHARS] [-r ROUNDS] [-h] [-p] [--stats]
                [--timings] [-v]
                files [files ...]

This tool allows to recursively compress an archive relying on Patool, a Python
 library supporting various archive formats.

Note: Password-protected compression is not supported.

positional arguments:
  files                 files to be archived

optional arguments:
  -c CHARSET            character set of random archive name (default: abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789)
  -d                    delete input files (default: False)
  -f FORMATS            compression algorithms (default: all)
  -n NCHARS             length of random archive name (default: 8)
  -r ROUNDS, --rounds ROUNDS
                        number of compression rounds (default: 10)
  --reverse             reverse byte order (default: False)

data options:
  --data DATA           data to be embedded (default: None)
  --chunks CHUNKS       number of chunks the data should be split in (default: 10)

extra arguments:
  -h, --help            show this help message and exit
  -p, --progress        progress mode (default: False)
  -v, --verbose         verbose mode (default: False)

timing arguments:
  --stats               display execution time stats at exit (default: False)
  --timings             display time stats during execution (default: False)

Usage examples:
  rec-comp file1 file2 file3 -r 10
  rec-comp file -c abcd -n 10
  rec-comp -p

$ rec-comp file1 file2 file3 -r 10 -p

Decompression

$ rec-decomp -h
usage: rec-decomp [-d] [-p] [-h] [--stats] [--timings] [-v] archive

This tool allows to recursively decompress an archive relying on Patool, a
 Python library supporting various archive formats.

Note: Password-protected compression is not supported yet. If the tool freezes
       while decompressing, it may be necessary to press enter to submit a blank
       password, which will stop decompression.

positional arguments:
  archive        input archive

optional arguments:
  -d             delete input archive (default: False)
  -p             print resulting file, if possible (default: False)

extra arguments:
  -h, --help     show this help message and exit
  -v, --verbose  verbose mode (default: False)

timing arguments:
  --stats        display execution time stats at exit (default: False)
  --timings      display time stats during execution (default: False)

Usage examples:
  rec-decomp archive.zip
  rec-decomp archive.zip -d
