A new version of <a href="http://hackage.haskell.org/cgi-bin/hackage-scripts/package/Yampa-0.9.2">yampa</a> was uploaded to hackage today, but it&#39;s <a href="http://www.haskell.org/yampa/">website</a> hasn&#39;t been updated since 2004. <br>
<br><a href="http://hackage.haskell.org/cgi-bin/hackage-scripts/package/SpaceInvaders-0.4.1">SpaceInvaders</a> depends on HGL and Yampa.<br><br>There&#39;s been more noise around <a href="http://haskell.org/haskellwiki/Phooey">Phooey</a> and <a href="http://haskell.org/haskellwiki/TV">TV</a> in recent months, but afaik, hasn&#39;t been used for any applications yet.<br>
<br>There was also <a href="http://twan.home.fmf.nl/parsep/">ParseP</a> which seems to tackle a similar problem, but from the perspective of a more general parsing library.<br><br>Are there other purely functional reactive libraries in active development?&nbsp; Why might one choose one over another?<br>
<br>Thanks,<br>Greg<br><br><br>
