Lift whatever string-match or regexp function you need to the monad? For example, it looks like you could match isInfixOf on (/tmp); here's an existing example

Is the previous code right? I'm seeing an only single quote. Overall, I don't understand the example... what it has to do the first line with the last one? I'm sorry, I'm just starting to learn haskell to configure my xmonad.hs.

In pentadactyl (a firefox addon) you can write in an external editor instead a textbox, by default it spawns a gvim window and everytime it opens a pentadactyl.txt in tmp folder. Imho that behaviour is way more easier writing on a floating window.

Using xprop I found the WM_NAME it's the only variable that doesn't change, so I thought that using it in my myManageHook would do it.

$ xprop | grep 'WM_NAME' WM_NAME(STRING) = "pentadactyl.txt (/tmp) - GVIM"

myManageHook = (composeAll , concat $    [ , [ className =? "stalonetray"     --> doIgnore]    -- a lot of output removed --    , [ title =? "pentadactyl.txt (/tmp) - GVIM"    --> doFloat]    ]

I restarted xmonad, reopened the editor and I found that it doesn't work, I tried to check wm_name again, and guess what?

WM_NAME(STRING) = "pentadactyl.txt (/tmp) - GVIM1"

Obviously the last part "GVIM" changes all the time, so I can't know in advance which is gonna pick.

There's some way to regexp the wm_name part? Until now, I couldn't find anything about this topic :(

It's a backquote, and yes, there are two of them, surrounding "isInfixOf".

Yep, I can see that... I was asking for the quote after doSideFloat in the last line: ..."Call with " -?> doSideFloat' CE ]

...

The first one defined an operator (~?); the second showed how to use it.

Thanks, the "-?>" I guess it's another operator? I'm still trying to get used to haskell... way different about from what I used too.

Oh.  That's not behaving as a quote; it's behaving as a "prime" (following mathematical conventions).  Within an identifier (that is, not as the first character) single quotes are part of the identifier.  So you can have names like

    doSideFloat'     a'b'c     y''' (that's 3 primes)

Hahaha, another surprise :P.

Yes, it's defined in XMonad.Hooks.ManageHelpers.

http://xmonad.org/xmonad-docs/xmonad-contrib/XMonad-Hooks-ManageHelpers.html...

Thanks! I'm going to read the documentation.

Unless you have previous experience with an ML-family functional language, yes.

Thanks again for your help :). I just found Real World Haskell which until now looks waay more easy to read that 'Gentle introduction to haskell', which by the way of "gentle" has nothing. Can you suggest any other reference to someone that has some background working with web technologies, ruby and some python?
