Hi,
Hoogle is definitely not deprecated. The reason you can't yet search
all packages simultaneously is that it consumes too many resources -
the number of Haskell packages exploded at a time when I wasn't able
to spend enough time to allow Hoogle to keep up. It's definitely

Yeah! It does sound a bit pointless. Hoogle should search everything
by default, and then you can refine your search by clicking on the '+'
or '-' on the packages that appear on the left menu.

Wait - there's a semantic difference:
hoogle does understand type signatures
(e.g., it can specialize them, or flip arguments of functions)
while hayoo just treats signatures as strings

Hi,
I noticed Hayoo appears as a link in the toolbox of
http://hackage.haskell.org and also that Hayoo seems to display better
results than Hoogle. For example, if you search for 'PublicKey' in
Hayoo, you will get several results from Hackage libraries, such as,
'crypto-pubkey' and 'crypto-api'.
Sorry yes - it was just a caching problem. Now I've cleared the Chrome
cache, it is all working beautifully again.

It's actually implemented as +nameOfLibrary. Hoogling for "rstrip +missingh"

it seems Hayoo only does exact (string?) match on types,

E.g., search for "String -> Int".
Hoogle finds length :: [a]-> Int as well,
I think Hayoo doesn't.

Hi Alvaro,
by default Hoogle only searches some standard set of packages, which is
only a relatively small subset of all Hackage content. From
http://www.haskell.org/haskellwiki/Hoogle#Scope_of_Web_Searches :
> Using the standard web interface, Hoogle searches: array, arrows, base,
bytestring,
Searching Hoogle for symbols like `rstrip` or `lstrip` produces "No
results found" for me, even though they exist in the MissingH library.
To wit:

Outside of flags to enable display of modules specific to each major

on hoogle having some sort of list of modules for each platform, which

The Network.Socket module works fine on Windows. The original Winsock

It just takes a bit of massaging to do what you want:

ghci> :t (?f some_func [?a .. ?b])
Here's an example:
Prelude> :t ?f map [?a .. ?b]
?f map [?a .. ?b] :: forall t a b t1.

Well, as I said, replacing one term with another transforms
one signature into the other. I guess you can't curry type
constructors as easily as functions - or at least, Hoogle
currently doesn't like it.
Yes, currying of type constructors is much less common, and en

Hi
Try doing a Hoogle search for "c1 (c2 x) -> c2 (c1 x)".
Hoogle correctly states that Data.Traversable.sequence will
do it for you.
Now try doing "c1 k (c2 x) -> c2 (c1 k x)". The 'sequence'
function will also do this, but now Hoogle returns 0 results.
This is p

I could probably elaborate on that point further.

Hoogle does not search the general web, just the libraries supplied
with GHC. A quick scan of the first few Google result
Hi Haskellers:
I have just been asked for usage of timer in haskell. Which I did not
remember clearly. So I ask the search engine.
In Hoogle: timer
In Google: haskell timer
After I tried these, I wonder, when and how often the hoogle update its
database? And, could hoogle search range cover the
1 - 100 of 134 matches
