@hackage flow2dot0.3

This is a tool to generate nice sequence (flow) diagrams from textual descriptions, written in Haskell.

This tool generates a diagram description, which could be made into a nice picture with help of Graphviz (www.graphviz.org)

To try it out, run: runhaskell flow2dot.hs sample.flow | dot -T png -o sample.png and view "sample.png" with your favorite picture viewer. If you dont get a nice picture and get something else (for example, ugly segfault from dot), try upgrading to latest Graphviz (2.12 or later)

If you want to use national alphabets, make sure that your .flow files are encoded in UTF-8. If you want to tweak the output - read Dot manual and use it for scaling, colors, pagination etc.

Latest version could be obtained via: darcs pull http://adept.linux.kiev.ua/repos/flow2dot/

Thanks to Cale, quicksilver and roconnor from #haskell for suggestions on how to modularize this. Thanks to Dema from haskell@conference.jabber.ru for win32 testing. Gwern0 helped to adapt this to GHC 6.8.2
