Crystal XZ

Crystal bindings to the XZ (lzma) compression library. Requires liblzma version 5.2.4 and/or higher.

Installation

1. Add the dependency to your shard.yml:

   dependencies:
     xz:
       github: naqvis/xz.cr
   

2. Run shards install

Usage

require "xz"

XZ shard provides both Compress::XZ::Reader and Compress::XZ::Writer.

Example: decompress an xz file

require "xz"

string = File.open("file.xz") do |file|
   Compress::XZ::Reader.open(file) do |xz|
     xz.gets_to_end
   end
end
pp string

Example: compress to xz compression format

require "xz"

File.write("file.txt", "abcd")

File.open("./file.txt", "r") do |input_file|
  File.open("./file.xz", "w") do |output_file|
    Compress::XZ::Writer.open(output_file) do |xz|
      IO.copy(input_file, xz)
    end
  end
end
