Single Monitor with Multiple Workspaces
by Eyal Erez 09 Jul '20

09 Jul '20

Hi, I used to have two monitors and I loved xmonad's ability to switch which workspace was visible on each. That allowed me to set up multiple windows in a workspace and then pop them all in and out as needed. I've since replaced them with a single ultra-wide monitor. I thought it would be amazing, if I can pop in two workspaces side by side on the same monitor and control each independently as if they were on two monitors. Could something like that be possible? -- *Eyal Erez <**oneself(a)gmail.com* <oneself(a)gmail.com>*>* There are 10 types of people, those who know binary and those who don't.

Change the visibility of windows
by Daniel Trstenjak 09 Jul '20

09 Jul '20

Hi, is there a way to temporary change the visibility of windows? Sometimes I want to temporary only see two windows of the workspace side by side and afterwards switch back to see all windows. Something like tagging the two windows and then switching to a layout only displaying the tagged. Perhaps even being able to tag windows from different workspaces might be a nice feature. Greetings, Daniel

incorrect focus after closing a window
by joe skinner 27 Jun '20

27 Jun '20

I currently use the following to get windows inserted in the order that I want and it works well. , manageHook=insertPosition Below Newer <+> manageHook def <+> manageDocks My issue is that when I close a window I always get the wrong window focused as it does not take into account the order in which it was created. Is there any way that this can be overcome? Thanks Joe

Opera Browser Window Borders Missing
by Eyal Erez 25 Jun '20

25 Jun '20

Hi, I have my active and inactive window borders set to orange and grey respectively. This works well for all windows. However, I've recently installed the Opera browser, and for some reason, the borders are not coming up at all. They seem transparent -- meaning, there's a gap between the Opera window and other windows, the edge of the screen, and xmobar on all sides. I seem to remember that this happened for Chrome as well, until I set "Use system title bar and borders" to on in the settings. I haven't been able to find something similar for Opera. Is there anyway to fix this? Thank you -- There are 10 types of people, those who know binary and those who don't.

XMonad.Actions.Search: Issue with escaped URL
by Christian Heinrich 12 Jun '20

12 Jun '20

Hi everyone, I've started to use XMonad.Actions.Search and I'm trying to define my own SearchEngine as follows: > searchFunc :: String -> String > searchFunc s = "https://de.pons.com/übersetzung/französisch-deutsch/" ++ (escape s) > pons = searchEngineF "pons" searchFunc The german umlauts ü and ö are actually part of the URL. According to the documentation, searchEngineF should not handle any escaping (unlike searchEngine), but the URL that is opened for "a" is https://de.pons.com/%C3%83%C2%BCbersetzung/franz%C3%83%C2%B6sisch-deutsch/a I can't find what I'm doing wrong even when looking at the source. Could anyone point out to me how to open that URL without escaping anything? I'm just surprised that the base-URL is escaped as well, and not just the argument. I'm pretty new to Haskell and would be grateful for any hint. Thanks! Christian

Correct config file for xmonad 0.15
by Alain Bertrand 09 May '20

09 May '20

Hi, I have installed Lubuntu 20.04 on my laptop and xmonad doesn't redraw it background. That is if I am on workspace 1 , and switch to a workspace with no window, the background of the new workspace is made by the windows of workspace 1. I do have some warnings in xmonad.errors but don't feel they are the explanation of the problem I encounter. Would somebody have a workaround ? Not being able to use Xmonad would be hard to bear.

How to trigger Xmonad.Prompt.AddFile on recurrent times?
by Alejandro Garcia 25 Apr '20

25 Apr '20

Hello In order to help with my personal productivity. I want to register what I'm doing every 15 minutes or so. And using Xmonad.Prompt.AddFile is very easy. Currently I launch it with a key combination and I can start writing what I'm doing in this moment. However, no I would like to automatically launch AddFile every 15 minutes... Ideally from cron (which I know) or maybe xmonad has a way to do it itself? -- Alejandro García F. (elviejo) Too brief? Here's why! http://emailcharter.org EOM – End Of Message.

why spawn (and safeSpawn, etc) use encodeString?
by Platon Pronko 17 Apr '20

17 Apr '20

Hi! I noticed that spawn mangled my unicode characters - instead of my unicode character the called program recieved garbage. Looking deeper I found out that spawn pre-processes the string with `encodeString` function. `encodeString` first converts [Char] into [Word8], and then converts each individual Word8 back into Char. Since unicode Char will be converted into multiple Word8, the resulting string would be quite different. Example: Prelude> import Codec.Binary.UTF8.String Prelude Codec.Binary.UTF8.String> encodeString "Ø" "\195\152" Prelude Codec.Binary.UTF8.String> putStrLn "Ø" Ø Prelude Codec.Binary.UTF8.String> putStrLn $ encodeString "Ø" ÃPrelude Codec.Binary.UTF8.String> Is there a reason why xmonad uses `encodeString` here? I implemented a copy of the function that doesn't use `encodeString`, seems to work okay: safeSpawnUnicode :: MonadIO m => FilePath -> [String] -> m () safeSpawnUnicode prog args = io $ void $ forkProcess $ do uninstallSignalHandlers _ <- createSession executeFile prog True args Nothing Best regards, Platon Pronko

A proper way to make XMonad.Actions.WindowMenu configurable?
by Michal J. 05 Apr '20

05 Apr '20

Hello friendly folks, I'm a relative newb to both xmonad and Haskell, and for a while I wrestled with a seemingly simple task -- to make XMonad.Actions.WindowMenu (from xmonad-contrib) configurable. Essentially I wanted to go from: windowMenu :: X () windowMenu = ... to: windowMenu :: ??? -> X () windowMenu actions = ... so I can customize the actions that pop up. So I can bind different menus to different key combos. Now, I documented some of my struggles at Stack Overflow: https://stackoverflow.com/q/61001342/1177128 and eventually came up with a solution (with help from others!): https://stackoverflow.com/a/61013887/1177128 But given that grepping the xmonad and xmonad-contrib sources for ":: XConf ->" returns exactly 1 result (spoiler: `runX` in `Core.hs`), I'm pretty sure I'm holding it wrong: ```haskell defaultActions :: XConf -> [(String, X ())] defaultActions = do tags <- asks (workspaces . config) return ([ ("Cancel menu", return ()) , ("Close" , kill) , ("Maximize" , withFocused $ \w -> sendMessage $ maximizeRestore w) , ("Minimize" , withFocused $ \w -> minimizeWindow w) ] ++ [ ("Move to " ++ tag, windows $ W.shift tag) | tag <- tags ]) windowMenu' :: (XConf -> [(String, X ())]) -> X () windowMenu' actions = withFocused $ \w -> do acts <- asks actions Rectangle x y wh ht <- getSize w Rectangle sx sy swh sht <- gets $ screenRect . W.screenDetail . W.current . windowset let originFractX = (fi x - fi sx + fi wh / 2) / fi swh originFractY = (fi y - fi sy + fi ht / 2) / fi sht gsConfig = (buildDefaultGSConfig colorizer) { gs_originFractX = originFractX , gs_originFractY = originFractY } runSelectedAction gsConfig acts -- now it composes well, and I can pass in my own `actions` to `windowMenu` windowMenu = windowMenu' defaultActions ``` Can anyone well versed in the idiosyncrasies of Haskell and XMonad please point out what would be the proper -- nay, canonical -- solution if it were done by someone who actually knows what they're doing? It'd be greatly appreciated. :-) Cheers, Michal PS: If the refactor seems like I really have no clue what's going on... well... I don't. And if you have a pointer to some text I should read to understand all this better, I'm all ears.

Problem upgrading xmonad via cabal
by Eyal Erez 11 Mar '20

11 Mar '20

Hi, I've recently tried to upgrade xmonad to the latest version but have been experiencing some problems. My guess is that the version I'm getting from cabal is conflicting with Fedora's packaged version, but I'm not sure how to disentangle. I've tried the following, any suggestions would be most welcome: > cabal --version cabal-install version 2.4.1.0 compiled using version 2.4.1.0 of the Cabal library > cabal update Warning: The update command is a part of the legacy v1 style of cabal usage. Please switch to using either the new project style and the new-update command or the legacy v1-update alias as new-style projects will become the default in the next version of cabal-install. Please file a bug if you cannot replicate a working v1- use case with the new-style commands. For more information, see: https://wiki.haskell.org/Cabal/NewBuild Downloading the latest package list from hackage.haskell.org To revert to previous state run: cabal update --index-state='2020-02-24T08:44:25Z' > cabal install xmonad Warning: The install command is a part of the legacy v1 style of cabal usage. Please switch to using either the new project style and the new-install command or the legacy v1-install alias as new-style projects will become the default in the next version of cabal-install. Please file a bug if you cannot replicate a working v1- use case with the new-style commands. For more information, see: https://wiki.haskell.org/Cabal/NewBuild Resolving dependencies... All the requested packages are already installed: xmonad-0.15 Use --reinstall if you want to reinstall anyway. > cabal install xmonad --reinstall Warning: The install command is a part of the legacy v1 style of cabal usage. Please switch to using either the new project style and the new-install command or the legacy v1-install alias as new-style projects will become the default in the next version of cabal-install. Please file a bug if you cannot replicate a working v1- use case with the new-style commands. For more information, see: https://wiki.haskell.org/Cabal/NewBuild Resolving dependencies... In order, the following would be installed: xmonad-0.15 (reinstall) cabal: The following packages are likely to be broken by the reinstalls: xmonad-contrib-0.16 xmonad-contrib-0.15 Use --force-reinstalls if you want to install anyway.
