Twitgraph at Github

February 1, 2012

I just released the sources of my hashtag graph generator here in Github with a BSD-style licence. I was planning to write a tutorial for it, but it is a single file package so I documented everything in source file in a newbie-friendly -at least I hope so- manner.

Some terms (e.g. search-ref) are part of the protocol defined in cl-twitter, they aren’t explained in twitgraph documentation.

I only tested it on Arch Linux with SBCL 1.0.54 (AMD64), graph generation is done via Graphviz. Source code is ANSI CL compliant. so it should work on all ANSI CL implementations and platforms that are supported by package dependencies + Graphviz.

All suggestions/critique about the code are welcome and appreciated. Also, do not hesitate asking questions or requesting a tutorial if the source documentation does not make sense.
