In the meantime, the trick used by e.g. Fedora's default xmonad configuration is environment variables.

Aha, that will do nicely. Thanks! And I agree, a --user-arg param would be convenient. Regards, Chris Bell Ph.D. Student University of South Florida College of Engineering Department of Computer Science and Engineering NarMOS Research Team

Curious what code you tried

I had a nasty little shell script that called xrandr, processed the output, and returned a number indicating the number of screens. I never did figure out what made it go wrong. I didn't even know the Xinerama package existed (still new to Haskell/XMonad); I'll have to try that out. On a related note, any recommendations for resources to help me wrap my head around/understand the capabilities of Haskell? Thanks!

Thanks for the suggestion! Yet another package I didn't know existed. I don't mind having to relaunch xmonad when I switch screen layouts, so that bug won't bother me much. I just need to discern how to configure/implement it. On Tue, Oct 7, 2014 at 12:49 AM, Devin Mullins wrote:

I've been working my way through Learn You a Haskell. It's been overwhelmingly helpful. My biggest obstacle is that I've never worked with a pure functional language before, so most of my old paradigms don't apply. You're probably right; picking a problem and beating my head against it until I solve it is probably the best way.

That's a big question. For a general intro, I've heard good things about Learn You a Haskell [1], and of course Real World Haskell [2] was co-written by one of the creators of xmonad. Myself, I just learned through my usual combination of trial-and-error and perusing blogs, mailing lists, random bits of code, and the spec.

As for what your head needs wrapping around, I would need more information, but for many people the first barrier is the syntax, so... Lesson #1: function calls look like `f 1 2` instead of `f(1, 2)`. There is actually a good reason for this. Exercise: Find out what that reason is. Class dismissed.

You may have some luck with XMonad.Hooks.DynamicBars (http://xmonad.org/xmonad-docs/xmonad-contrib/XMonad-Hooks-DynamicBars.html). It's for dynamically starting and stopping status bars on each screen, but you could probably use it to manage other things as well. I've been using it for a while now, and it works great for having one xmobar instance per screen.

Are there any examples available of how it's used? -- Hubert Chathi - Email/Jabber: hubert@uhoreg.ca - http://www.uhoreg.ca/ PGP/GnuPG key: 4096R/113A1368 (Key available at pool.sks-keyservers.net) Fingerprint: F24C F749 6C73 DDB8 DCB8 72DE B2DE 88D3 113A 1368
