ManageHook question
Hi all, If I wasn't still an almost total Haskell newbie, this would probably be easy for me to answer for myself. As is... If I want to have a manage hook that will run anytime a window title contains a string how do I do that? For example title =? 'downloads' --> doIgnore but instead of exactly matching title against 'downloads' we want to run the doIgnore for any window whose title contains 'downloads'. -Sean-

It's kinda ugly: ("downloads" `isInfixOf`) `fmap` title --> doIgnore or equivalently fmap (isInfixOf "downloads") title --> doIgnore More generally, to apply a comparison operation of some kind to a Query string, use "fmap" to run it "inside" the Query. So you can read the first version somewhat naturally as 'run ("downloads" `isInfixOf` x) with "x" being the string inside of "title"'. (You will probably need "import Data.List (isInfixOf)" at the top of your xmonad.hs.) - -- brandon s. allbery [linux,solaris,freebsd,perl] allbery.b@gmail.com system administrator [openafs,heimdal,too many hats] kf8nh -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (Darwin) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk1x6hoACgkQIn7hlCsL25VYYwCfbavF3cPlpTtcM8pq6K2gGsP+ Vr8An3O1VH7zrShw3s17E8TyBOZRK6He =PJin -----END PGP SIGNATURE-----
Thanks Brandon.
I'm constantly amused by what haskell I can figure out to get stuff
working in and what I can't.
I'm going to dig deeper into your explanation and hopefully really
learn something.
