Hoogle search scope question -- was: [HXT] Simple question
I have a hoogle question. While I was reading the HXT discussion
(below), I tried to search "runX" and "readString" in Hoogle (since I
am new to HXT and Arrows). But neither search yielded any result and I
had to use google to find the Haskell docs.
So I am wondering what is the scope of Hoogle that people can search?
Only things in the standard library? How much does it cover in the
Hackage? I tried to find the scope description in the Tutorial but in
vain. It is fair to say if someone needs to use Hoogle, he/she
probably has no idea what he is looking for, needless to say, what is
in scope of Hoogle or what is not.
Thanks,
Steve

Seems rather strange for me, I've just installed HXT and got this:
Prelude Text.XML.HXT.Arrow> runX $ readString [(a_validate,"0")] "<this> </this>" >>> writeDocumentToString [] ["<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n<this> </this>"]
Everything works fine except for the fact that all the nodes <this> </this> (that is, a space (an XML text node whose contents are a single space character) within a <this> element node) get transformed to a <this/> element node,

Hi
I have a hoogle question. While I was reading the HXT discussion (below), I tried to search "runX" and "readString" in Hoogle (since I am new to HXT and Arrows). But neither search yielded any result and I had to use google to find the Haskell docs.

http://www.haskell.org/haskellwiki/Hoogle#Scope_of_Searches (new section just added)
Only things in the standard library?
Mainly those things distributed with GHC.
How much does it cover in the Hackage?
Virtually none. This will change at some point in the future.
I tried to find the scope description in the Tutorial but in vain. It is fair to say if someone needs to use Hoogle, he/she probably has no idea what he is looking for, needless to say, what is in scope of Hoogle or what is not.
In general, Hoogle is designed if you want to find a generally applicable function. If you are using HXT, then you probably know whether you want a general function or one that works over the HXT data types/classes/monads etc. I do want to expand Hoogle to search everything on hackage, and to have package specific searches as well, but it requires more coding first.
