Controlling Window Location with XMonad.Layout.ThreeColumns
by Eyal Erez 12 Jan '17

12 Jan '17

Hi, I have an ultrawide monitor and so I use ThreeColumns most of the time. I create it like so: ThreeColMid 1 (3/100) (1/3) This works fine, however, I'm getting some strange behavior when creating an closing windows. I hope I can explain this with a small diagram which shows window location as I create and close apps: CREATE 1 [ a ] 2 [b][ a ] 3 [a][c][b] CLOSE 1 [a][c][b] 2 [b][ a ] 3 [ a ] So, when going from 2 to 3 open windows, window "a" and "b" switch location for some reason. in step #2 "b" is on the left and "a" is on the right, but when a third window is added (or removed) they swap locations. This is very confusing. Is there anyway I can cause this to stop happening? It would also be nice if window "b" was created into the active location, but that's more of a nitpick. Thank you -- There are 10 types of people, those who know binary and those who don't.

Ready for v0.13?
by Peter Jones 12 Jan '17

12 Jan '17

It's been almost a year since we released v0.12 (which had an unfortunate struts bug). We should have done this a long time ago but better late than never. With my favorite holiday behind us, I have some spare time I could use to drive another release. But I'm going to need everyone's help. I'd like to close as many issues and pull requests as we can before making a release. And of course, getting master tested before the release would be a good idea too ;) Want to help? Pick one or more of the following: 1. Look through the list of pull requests and find one that sounds interesting to you. Merge it into your local xmonad and try it out: https://github.com/xmonad/xmonad/pulls https://github.com/xmonad/xmonad-contrib/pulls 2. Look through the list of issues and: a) Add a comment with more details if the bug is also affecting you b) If you think you can fix it, add a comment and then get working! 3. If you are interested in testing master before the release please let us know so we can start a dialog. What if you want to help but don't know how to build xmonad from source, or don't know how to use git? No problem! Reach out to me, I'd be more than happy to help you out. Either post a message to this mailing list, send me a direct email, or reach out to me on IRC, I'm pmade on #xmonad (on freenode). (We probably need a CONTRIBUTING.md file in the repo. I can work on that too.) I love xmonad and I know a lot of you do too. Let's make v0.13 a good release and make future releases easier. Thanks! -- Peter Jones, Founder, Devalot.com Defending the honor of good code

contrib: fixing raiseNext stuck between 2 workspaces
by Loïc 13 Nov '16

13 Nov '16

Dear all, I'm a big fan of raiseNext(Maybe) action from xmonad-contrib. However, there is a quite annoying bug, reported some years ago still active: raiseNext cycles only between 2 workspaces, making impossible to cycle through the entire list of windows (for a full description, not by me, see https://code.google.com/archive/p/xmonad/issues/284 ) The reason is that raiseNext calls allWindows from xmonad StackSet, which relies on a list of workspaces built as follows: the current workspace is put first, followed by visible then hidden workspaces. Thus the ordering of workspaces is not absolute, which is why raiseNext will cycle only between the current and another workspace. I found the following fix: - create a allWindowsSorted function in Xmonad.StackSet which relies on a list of workspaces sorted by their tags - call W.allWindowsSorted instead of W.allWindows in raiseNext. The patch is given below for 0.12. Let me know if it is an appropriate way to fix the bug. If so, I can create the pull requests for xmonad and xmonad-contrib that apply on current master. Otherwise, let me know what solution you would prefer. It would be nice that 0.13 contains a fix.

Can avoidStruts stop working?
by Jan Christoph Uhde 06 Nov '16

06 Nov '16

Hi, I experience the same issues as in: https://mail.haskell.org/pipermail/xmonad/2016-March/015047.html avoidStruts works for me in 0.11.1 (not compatible with the newest ghc 8.x.y in debian sid). In version 0.12 (cabal-default) it does not work on the first workspace, but starts working after pressing (mod-shift-space). In current git version xmonad (8b055621e92e7ade127043e968f50713c15a00a0) / xmonad-contrib (ec5f9a9e59ed5fa6bbd4c3850e4025526155f86e) my xmobar is never visible as soon as there is any other window. I have tried to work with sanboxes and different ghc versions but it is all very painful as I have to cd into the correct sandbox and even then xmonad must use a certain ghc version on startup when it compiles it's configuration. Please let me know how I can help debugging the problem. I know a bit programming and a few haskell basics. So please give me enough details to be helpful. You will find me as obiwahn in #xmonad(a)freenode.net. Regards Jan Christoph Uhde
