Pyshortstringcompression is a project mainly written in ..., it's free.
Compress short strings, using the Huffman algorithm.
Compress and decompress short strings.
We precompute a Huffman tree (dictionary) for our corpus, and this corpus is not stored in any way in the compressed strings.
WARNING: When decompressing, make sure you know what dictionary was used to compress the string, or you're hosed.
For happy porting, the compression dictionary is given in a human-readable format. Pull requests should be directed at: https://github.com/antirez/smaz
