Decompressing a Gzip File by Hand

• infgen

  3 203 4.6 C

  Deflate disassember to convert a deflate, zlib, or gzip stream into a readable form.

For anyone looking to write their own Deflate/Gzip/Zlib, I would recommend looking at the little program called `infgen`:

> infgen is a deflate stream disassembler. It will read a gzip, zlib, or raw deflate stream, and output a readable description of the contents.

  1 2 0.0 C

  Naive implementation of DEFLATE in C for decompressing gzip files (RFC 1951, RFC 1952).

Programming a gzip (deflate) decompressor is a really good learning project. I did it last year, ultimately producing a pretty poor but working implementation [0]. I ended up modifying Mark Adler's puff example program to see the intermediary tables it produces to help debug my own implementation. I wish I had known about infgen (also by Adler). The other resource I would recommend, beyond the official specs is this article by Joshua Davies[1], also mentioned in the original post here.
