The documentation for (!>) in XMonad.Actions.Search is misleading. The documentation says "> multiEngine = intelligent (wikipedia !> mathworld !> (prefixAware google))", but this syntax doesn't provide the expected behaviour.
See
*XMonad.Actions.Search> use (wikipedia !> hoogle !> prefixAware google) "hoogle:foo" "http://www.google.com/search?num=100&q=hoogle%3Afoo"
compared to:
*XMonad.Actions.Search> use (wikipedia !> (hoogle !> (prefixAware google))) "hoogle:foo" "http://www.haskell.org/hoogle/?q=foo"
I propose changing the documentation from <snip>"intelligent (wikipedia !> mathworld !> (prefixAware google))"</snip> to <snip>"intelligent (wikipedia !> (mathworld !> (prefixAware google)))"</snip>
I never use this particular functionality (nor did I write it; Michal Trybus apparently did), but is this *desired* behavior? I mean, adding a infixity declaration would seem to bring the code back into correspondence with the documentation rather than the other way around. If you add hunk ./XMonad/Actions/Search.hs 327 +infixr 7 !> + Then GHCi seems to give the documentation's results: *XMonad.Actions.Search Control.Monad Data.Char Data.List> use (wikipedia !> hoogle !> prefixAware google) "hoogle:foo" Loading package X11-1.5.0.0 ... linking ... done.
