Hi Neil, This is a great addition! There's several packages up there that I want to search. A couple of small bug reports though: 1. Searching using a package name that isn't all lower case results in nothing (e.g. (a -> b) -> f a -> f b +InfixApplicative gives no results, while (a -> b) -> f a -> f b +infixapplicative gives 2). 2. Searching with the +package syntax seems to remove all other possible results. Perhaps it would be nice to show results from the default library set below. And one feature request: If you get the package name wrong (i.e. specify a package that hoogle can't see), it would be nice for it to report something like google does -- maybe you meant xyz.

Hi,
I am pleased to annouce that the Hoogle on http://haskell.org/hoogle will now search lots of the libraries present on hackage. For example, to search for the parse function in tagsoup, try:
"parse +tagsoup" (http://haskell.org/hoogle/?hoogle=parse+%2Btagsoup)
By default Hoogle will still search the default libraries it always has (cabal, base etc.) but now, by doing +packagename, you can search for any of the libraries listed at the bottom of this message. The work of generating the necessary search databases was done by Gwern Branwen, for which I am very grateful.
This is early work, and there are certain to be bugs. For example, when searching a package String /= [Char], documentation might not always be present, constructors containing functions might be a bit iffy, not all packages are present, no executables are present, if you mistype the +packagename it won't say anything. Hopefully these will all be addressed over time.
QUESTIONS
At the moment Hoogle searches will default to the small set of packages shipped with GHC. What should Hoogle default to? What compound sets of packages should be defined? i.e. there will probably be hlp which corresponds to all the Haskell Library Platform packages. This is a community tool, and these sorts of decisions are ones for the whole community. Otherwise by default you are likely to end up searching uniplate, tagsoup, safe, filepath, proposition, homeomorphic and binarydefer :-)
HELP ME
I can't currently recompile Hoogle, which is a bit of an issue! The haskell.org server gives the error message "timer_create: Operation not supported" on any relatively recent binaries created by GHC. I need to be able to compile the hoogle executable and upload it so it works. I used to do this using a copy of GHC 6.6.1 installed at York, but that was recently removed (6.6.0 has a bug which crashes hoogle, 6.8+ makes use of timer_create). How easy is it to make the haskell.org server support timer_create? How easy is it to generate binaries that don't depend on it? Anyone any good advice?
Please direct any follow-ups to haskell-cafe@
Thanks
Neil
