Status: New Owner: ---- New issue 495 by woofy1...@gmail.com: XMonad.Util.Run.safeRunInTerm does not work correctly http://code.google.com/p/xmonad/issues/detail?id=495 What steps will reproduce the problem? 1. Add a keybinding such as ((myModMask, xK_a ), safeRunInTerm "" "alsamixer" ) 2. Recompile and press M-a What is the expected output? What do you see instead? Expected: an xterm window with alsamixer running in it. Actual: nothing, xterm silently dies ('xterm: bad command line option "-e"') What version of the product are you using? On what operating system? xmonad 0.10-2 and xmonad-contrib 0.10-1 on Arch Linux. Please provide any additional information below. The definition of safeRunInTerm is broken: safeRunInTerm :: String -> String -> X () safeRunInTerm options command = asks (terminal . config) >>= \t -> safeSpawn t [options, " -e " ++ command] In the example, 'safeRunInTerm "" "alsamixer"' will run 'safeSpawn xterm ["", " -e alsamixer"], which is not the format that xterm, urxvt nor lxterminal expect (I have not tested with other terminals). A possible fix would be a definition such as safeRunInTermP :: [String] -> [String] -> X () safeRunInTermP options command = asks (terminal . config) >>= \t -> safeSpawn t (options ++ ["-e"] ++ command) which gives the desired behaviour for 'safeRunInTerm [] ["alsamixer"]', and correctly allows the specification of multiple arguments to both the terminal and the program to be run, eg 'safeRunInTerm ["-fg","#ffff00"] ["alsamixer","-V","capture"]' works correctly. The Strings passed to safeRunInTerm could be broken up with 'words' for a back compatible wrapper.

X.H.FadeInactive: Better support for multi monitor setups
by Jesper Reenberg 25 Apr '12

25 Apr '12

Hi, I have added fadeInactiveCurrentWSLogHook which given a rationale fades all windows that are not active. However unlike fadeInactiveLogHook, then it only does it for the current active workspace which makes it much easier to read the content on the other screens. Most of the code is courtesy of Morten Brøns-Pedersen. This is my first official patch, hope it is done correctly. -- Reenberg

[patch] Add emacs-like Keymap to XMonad.Prompt

Hello, please find attached the following patch. Feel free to change the function's name, in case the patch gets through that is. 1 patch for repository http://code.haskell.org/XMonadContrib: Sat Apr 21 03:10:55 CEST 2012 Carlos Lopez-Camey <c.lopez(a)kmels.net> * Add emacs-like Keymap in XMonad.Prompt Combination keys C-d, C-f, C-b, M-f, M-b, M-x, M-Backspace.

Similarly to X.L.PerWorkspace, it provides onHost, onHosts, modHost, and modHosts layout modifiers. It attempts to do smart hostname comparison, such that short names will be matched with short names and FQDNs with FQDNs. This module currently requires that $HOST be set in the environment. You can use System.Posix.Env.setEnv to do so in xmonad.hs if need be. (Properly, this should be done via the network library, but I'm trying to avoid adding that dependency.)

This may not always work as intended, since UrgencyHook likes to assume that a window being visible is sufficient to disable urgency notification; but with suppressWhen = Never it may work well enough. There is a report that if a new window is created at the wrong time, the wrong window may be marked urgent somehow. I seem to once again be revealing bugs in underlying packages, although a quick examination of X.H.UrgencyHook doesn't seem to show any way for the wrong window to be selected. ] [Adding use case for namedScratchpad. nicolas.dudebout@gatech.edu**20120122235843 Ignore-this: 44201e82bcd708cd7098f060345400f1 ] [Actions.WindowGo: typo fix - trim 's' per cub.uanic https://code.google.com/p/xmonad/issues/detail?id=491 gwern0@gmail.com**20120116224244 Ignore-this: fb1d55c1b4609069c55f13523c091260 ] [XMonad.Actions.PhysicalScreens: fix typo spotted by Chris Pick <haskell(a)chrispick.com> gwern0@gmail.com**20120115223013 Ignore-this: eb73b33b07dc58a36d3aa00bc8ac31c2 ] [roll back previous incorrect fix Daniel Wagner <daniel(a)wagner-home.com>**20120111214133 Ignore-this: 91496faef411e6ae3442498b528d119b ] [Extending: fix http://code.google.com/p/xmonad/issues/detail?id=490 gwern0@gmail.com**20120111211907 Ignore-this: 515afbed507c070d60ab547e98682f12 ] [another documentation patch: XMonadContrib.UpdatePointer -> XMonad.Actions.UpdatePointer Daniel Wagner <daniel(a)wagner-home.com>**20120111211226 Ignore-this: 1444e4a3f20ba442602ef1811d0b32c7 ] [documentation patch, fixes issue 490 Daniel Wagner <daniel(a)wagner-home.com>**20120111210832 Ignore-this: 8d899e15f9d1a657e9fc687e2f649f45 ] [X.H.EwmhDesktops note that fullscreenEventHook is not included in ewmh Adam Vogt <vogt.adam(a)gmail.com>**20120102211404 Ignore-this: 92f15fa93877c165158c8fbd24aa2360 Just a documentation fix (nomeata's suggestion at issue 339). ] [X.H.EwmhDesktops haddock formatting.

FAQ, UTF-8-Question
by 1126 19 Apr '12

19 Apr '12

Hello List! I don't know if this is the proper place to ask, but I don't know where else I should drop this. I browsed through the FAQ on the website and stumbled over a TODO at question 3.20 (http://www.haskell.org/haskellwiki/Xmonad/Frequently_asked_questions#How_ca…) I don't know whether xmonad >=0.8 supports (and uses) UTF-8 as default, but I guess that this could be answered and thus this answer could and should be adjusted ;) So, how is it with xmonad and UTF-8? Greetings from Cologne, Christian.

XMonad Efficiency
by Norbert Zeh 18 Apr '12

18 Apr '12

Hi folks, I must admit that I for now gave up on trying to make the decoration module more efficient. I tried two of the three ideas I had, and they didn't work well at all. My third idea (turning most of the lists in the decoration module into binary trees) is likely to work well, but for now I don't have time to implement it, particularly because it's not one of my main issues I would like to see addressed in xmonad. Related to the above, however, I noticed that even without decoration, fast focus switches drive my CPU usage up, much more so than in other non-tiling window managers. Running top gave me a surprising insight: it's not xmonad but the X server that consumes that many cpu cycles when focus switching. Here's my theory of the source of the issue: every focus change triggers the recomputation of the layout (as it should because some layouts rearrange windows in response to focus changes), and every recomputation of the layout updates the geometry of every window currently visible - that's a lot of work on the X server's side for a simple focus change. (1) Can anybody who is more familiar with the inner workings of xmonad core confirm that this is indeed what's going on? (2) A fairly simple fix for the above would be to cache the geometries of visible windows and tell the X server to update a window only if its geometry has in fact changed. Does anyone on the list have a feel for how hard it would be to add such a caching mechanism to xmonad core? Would it break anything? At this point, I'm simply pondering what can be done about it, as one of the reason's I'm using xmonad is that I want a lightweight desktop environment. (When fast focus changes drive one of my cores to 50%, that's hardly lightweight.) It'll be a while before I would get around to trying to implement the above.

Issue 505 in xmonad: Strip the executable file created during recompilation

Status: New Owner: ---- New issue 505 by jach...@gmail.com: Strip the executable file created during recompilation http://code.google.com/p/xmonad/issues/detail?id=505 What steps will reproduce the problem? 1. recompile xmonad I think it's a good idea to strip the executable file generated during recompilation to make it even more lightweight.

Issue 504 in xmonad: Suggested modification to XMonad.Actions.WindowsGo.runOrRaiseNext
by codesite-noreply＠google.com 16 Apr '12

Status: New Owner: ---- New issue 504 by dansp...@gmail.com: Suggested modification to XMonad.Actions.WindowsGo.runOrRaiseNext http://code.google.com/p/xmonad/issues/detail?id=504 Best explained by an example: Currently: I have 2 instances of chrome running: Chrome1 (runRaiseNext Pidgin) Pidgin (runRaiseNext Chrome) Chrome2 (runRaiseNext Chrome) Chrome1 Proposed Change: I have 2 instances of chrome running: Chrome1 (runRaiseNext Pidgin) Pidgin (runRaiseNext Chrome) Chrome1 (runRaiseNext Chrome) Chrome2 I think the current behavior is not ideal, as it makes it difficult to swap between a particular window of an application and any other window. Very simply put my suggestion is NOT to cycle to the next window if the window we are coming from is not an instance of the window type.

Mail-plugin from xmobar
by 1126 16 Apr '12

16 Apr '12

Hello list! I'm not sure wether this is the right list to ask, but the Xmobar-List itself seems pretty dead to me. At least that's what I figured when browsing through the archives. Anyway, here's my problem: I try to add the mail-plugin to my xmobarrc and it complains: unexpected "s" expecting space or "Run" Here's what my xmobarrc looks like: Config { font = "xft:terminus-8" , bgColor = "#121212" , fgColor = "#ECECEC" , border = TopB , borderColor = "#F0E800" , position = Bottom , lowerOnStart = True , commands = [ Run Com "uname" ["-s", "-r"] "" 0 -- , Run MPD ["-t", "<state> (<lapsed>/<length>) | <artist> - <album> - <track> - <title>"] 10 , Run Mail [("inbox", "~/mail/mailboxes/uni/INBOX")] "mail" ] , sepChar = "%" , alignSep = "}{" , template = " %uname% }{ %mail% " } Any help is appreciated. Thank you :) Greetings from Cologne, Chris

Desktop Environment Integration
by Sean Allen 07 Apr '12

07 Apr '12

No right answer here. Just looking for information/advice about desktop environment integration. I've been using xmonad for about 16 months now and loving it. I currently use it integrated with gnome 2. About the only things I use gnome for are: gtk/desktop theming. easier multiple monitor setup. less x hassles. basically, has a shortcut to getting the basics configured. I'm going to be moving on from that machine soon and I'm trying to decide what to do. xmonad w/ nothing? <-- and handle all of the above issues manually gnome 2? gnome 3? kde? Problems using any of the above? Suggestions based on what I really care about with using gnome for best things to use? Seriously considering just going w/ xmonad but I really do like the little layer of 'not x' that I get with a gnome or kde or xfce etc. Thanks. -Sean-
