# Crystal Snappy  [](https://github.com/naqvis/snappy/releases) [](https://naqvis.github.io/snappy/) **Pure Crystal** implementation of [Snappy](https://github.com/google/snappy) compression format. This implementation supports more common case [Snappy Framing Format](https://github.com/google/snappy/blob/master/framing_format.txt). ## Installation 1. Add the dependency to your `shard.yml`: ```yaml dependencies: snappy: github: naqvis/snappy ``` 2. Run `shards install` ## Usage ```crystal require "snappy" ``` Module provides both `Compress::Snappy::Reader` and `Compress::Snappy::Writer` for use with streams like `IO` and/or files. It also provides `Compress::Snappy#decode` and `Compress::Snappy#encode` for uncompressing and compressing block formats. ## Example: decompress a snappy file # ```crystal require "snappy" File.write("file.sz", Bytes[255, 6, 0, 0, 115, 78, 97, 80, 112, 89, 1, 8, 0, 0, 104, 16, 130, 162, 97, 98, 99, 100]) string = File.open("file.sz") do |file| Compress::Snappy::Reader.open(file) do |sz| sz.gets_to_end end end string # => "abcd" ``` ## Example: compress a file to snappy format # ```crystal require "snappy" File.write("file.txt", "abcd") File.open("./file.txt", "r") do |input_file| File.open("./file.sz", "w") do |output_file| Compress::Snappy::Writer.open(output_file) do |sz| IO.copy(input_file, sz) end end end ``` Refer to **specs** for usage examples. ## Development To run all tests: ``` crystal spec ``` ## Contributing 1.
