Re: hoogling GHC

Hi Ranjit,

Is there a command line option that allows one to change the default prefix for the URL returned by searches?

No command line option, but you can change the .txt file itself by doing: @url http://www.haskell.org/ghc/docs/7.0.1/html/libraries/ghc-7.0.1/ @package ghc That should cause all the URL's in the GHC package that aren't explicit to have the above URL prepended to them. If there's demand, I can add a flag. Thanks, Neil

Hi Ranjit,

It sounds like you've got quite far. Sadly the manual is a bit out of date with respect to generating databases, but generally you need to produce ghc.txt on your own (using tools such as GHC's make system), then you can do:

hoogle convert ghc.txt default.hoo

Then you can run the local server with:

hoogle server --databases=.

That will find databases from the current directory, and serve them. Alternatively, if you put ghc.hoo (or default.hoo) in $DATADIR/databases it will pick them up automatically (where $DATADIR is whatever Cabal configured it to be). If you name the database as default.hoo it will be searched by default, if you name it ghc.hoo then "foo +ghc" will search for foo in the GHC database.

If a copy of ghc.txt was publicly available somewhere (and updated on some schedule), I'd be happy to make the official Hoogle server search it. Usually I just grab databases off Hackage, but I'll happily make an exception for GHC.

Thanks, Neil

The final stumbling block is getting the local webserver (hoogle server) to also search the above database. I'm sure there must be some simple way I can pass the name of the database as an argument when I boot up the server, but I can't seem to find it...

Have you found the various versions of the web deployment procedure yet?

deploy.txt:  instructions to follow manually (seems to be up-to-date) deploy.sh:   a shell script version to run locally (may be old) Deploy.hs:   a haskell version to run remotely (may also be old)

Obviously those scripts are tailored to the official installation, but there are some clues in there, for instance the steps

   cabal configure --datadir=/srv/web/haskell.org/hoogle/ --datasubdir=datadir -O2

and

   Upload datadir/resources to /srv/web/haskell.org/hoogle/datadir/resources    Upload datadir/databases/* to /srv/web/haskell.org/hoogle/datadir/databases
