A Hoogle error occurred.

I'm hoping that someone on Cafe might be able to offer a more helpful diagnosis than this ... erm ... terse ... error message.

Hi Jacek,

Hi Mark,

...

The lambdabot hoogle command requires hoogle to be installed locally, and to work.

Ah. Thank you. I had assumed that it connected to a server.

(Maybe my assumption was not entirely unfounded, given that the installation instructions for lambdabot blithely state that you "just cabal install lambdabot", nowhere suggesting that you might need to *manually* install some of its dependencies.)

...

Hence the first thing to ty is to run the hoogle command line version, something like:

hoogle '[a] -> a'

If that doesn't work, maybe try building some hoogle databases.

First I needed to 'cabal install hoogle'. Having done that, I needed to do what you suggested:

...

hoogle data

Which works swimmingly on Ubuntu, but fails on OS X, because wget seems to be hard-wired. I seem to recall that at least one of the packages that I installed over the last 2 days, automatically selected wget on Ubuntu, and curl on OS X.

Any pointers to the least painful way of getting 'hoogle data' to work on OS X?

Hi Jacek, Sorry I have no idea about OS X, hopefully someone else might know. I assume your test on OS X was with the latest hoogle version so that old issues would no longer be relevant: http://code.google.com/p/ndmitchell/issues/detail?id=429

Once I have the hoogle command line version working, it seems that lambdabot truncates its output to just the first 3 lines. Is this normal?

Yes.

Is there a way of customizing or changing this behaviour?

No (other than patching lambdabot), so the obvious workaround is to run the hoogle from the command line. Regards, Mark
