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 24 Apr '20

24 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.

11 Mar '20

Hi all, The xmonad.org domain is up for renewal again. I've been managing the domain since 2007, but I am no longer involved with the xmonad/Haskell community. Would someone be interested in taking over the domain? Thanks, David

Cycle recent non-empty workspaces (seeking PR review)
by ivan 08 Mar '20

08 Mar '20

Hi, I have a pull request in xmonad-contrib that adds two new features to XMonad.Actions.CycleRecentWS and I'm hoping to get it reviewed. The first feature is the ability to cycle through non-empty workspaces, or more generally, the ability to apply a user-provided predicate to the list of workspaces included in the cycle. The second feature is the ability to toggle back and forth between the current and most recent workspace. It's essentially a special case of cycling, but with simpler keyboard behavior -- repeated key presses toggle back and forth regardless of whether a modifier key has been released or not. There's not a whole lot to it, but it was fun to put together. The PR can be found at: https://github.com/xmonad/xmonad-contrib/pull/331 Thanks! Ivan

master window with fixed pixels layout.
by Alejandro Garcia 25 Jan '20

25 Jan '20

Hello first of all thank you for xmonad. the seconds I have saved every day by not having o drag and drop windows has given me more time to focus on what matters. get the job done and go home to play with my kids. I would like to know: Is there a window layout with the property that the width and height of the master window can be specified in pixels? my use case Is that I would like to record video casts. But it would be helpful for me if the window size of the master window stays fixed independently of the other windows open in the screen. I have checke FixedColumns. but on it the Width of the column is specified in a rare metric (characters?) plus the height is not fixed. Any recommendation ? Thanks in advance. -- Alejandro García F.
