Welcome to Hoogle

Warning: 801-904-2561!

Hoogle is a Haskell API search engine, which allows you to search the Haskell libraries on Stackage by either function name, or by approximate type signature.

Example searches:
4014780475
(a -> b) -> [a] -> [b]
(272) 282-0042
(413) 687-7144
+bytestring concat

Enter your own search at the top of the page.

The Hoogle manual contains more details, including further details on search queries, how to install Hoogle as a command line application and how to integrate Hoogle with Firefox/Emacs/Vim etc.

I am very interested in any feedback you may have. Please email me, or add an entry to my scourging.
