Well, does every lambdabot user want mueval and hoogle installed? Quite possibly not, but it would it be too much to ask, to have the documentation mention that they need to be installed separately if you intend to use them through lambdabot?

Re: [Haskell-cafe] lambdabot hoogle
Hi Jacek, 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. I see someone raised a bug for this: http://code.google.com/p/ndmitchell/issues/detail?id=434 - it's a very reasonable idea, which I'll include in the next version. Then if you have either wget or curl it will work. Any pointers to the least painful way of getting 'hoogle data' to work on OS X? Set up a shell alias so wget just calls curl? Install wget on OS X? If neither of these is feasible let me know and I'll rush out a new version of Hoogle.

Their interfaces are different. (Though maybe there's some option which makes curl sufficiently similar to wget, but I haven't bothered to look because ...) Install wget on OS X? Yes. Download, untar, configure, make, sudo make install ... did the trick in about two minutes. (Kinda obvious really, wasn't it!

I wonder a few quick greps for error messages in the source code might have turned up something useful without too much trouble, I wonder myself too. From my point of complete ignorance about how the packages are put together, and almost complete ignorance about cabal, it's difficult to judge when (and for how long) it's worth digging in with grep etc.: sometimes it will be a fruitful exercise, and sometimes not. Sometimes someone else will understand my problem faster than I can type grep, and sometimes not. So my tactic is to dig a little, then send out a cry for help, before digging further. but from skimming messages it seems your efforts have been at least as much as can reasonably be expected for installing a cabal package without big giant disclaimers.

Hi Jacek, The lambdabot hoogle command requires hoogle to be installed locally, and to work. 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. One way to do that is to run (on gentoo this needs to be run as root): hoogle data And if that works, to try it again: hoogle '[a] - a' And if all that works hopefully it should work in lambdabot. It works in the gentoo-haskell overlay. Regards, Mark ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
