Short String Compression for Ruby.

RSmaz is a pure-Ruby port of the Smaz short string compression algorithm by Salvatore Sanfilippo and released as a C library at: github.com/antirez/smaz/tree/master

I’ve done some initial cleanup of a pure Ruby->C port, but this is not yet complete. It does pass the specs, however! Feel free to clean it up as it’s a bit memory inefficient right now… :)

• MiniTest (in the Ruby 1.9 stdlib or ‘gem install minitest` on Ruby 1.8)

gem install rsmaz

require 'rsmaz'
r = RSmaz.compress("whatever")
puts RSmaz.decompress(r)

RSmaz.compress always returns a string with the binary encoding. The input can be any encoding, it will internally force it to binary and compress byte-by-byte.

RSmaz.decompress also always returns a string with the binary encoding. You must manually force the encoding back to the right one because RSmaz does not store information about the original encoding.
