I've decided to just go with randomR, simpler and guaranteed to work. Here's the PR: https://github.com/xmonad/xmonad-contrib/pull/573 P.S. I don't see an attachment in your email. But if there was simply an addition of "random >= 1.2" to build-depends (library and tests), then I've already tried and stack gave me lots of new errors (apparently the ghc snapshot it downloaded already includes random-1.1?).

Hi! I'm working on a PR right now. I've implemented the fix already, but I have trouble with tests - `stack test` uses random-1.1, and uniformR is not found there. Should I use randomR instead? Alternatively, how can I specify that a newer version of random should be used?

question about code in XMonad.Actions.GridSelect
by Platon Pronko 15 Jul '21

15 Jul '21

Hi! I'm looking at XMonad.Actions.GridSelect code (wanted to fix compilation warnings), and I stumbled over the following function. -- | Generates a Double from a string, trying to -- achieve a random distribution. -- We create a random seed from the sum of all characters -- in the string, and use it to generate a ratio between 0 and 1 stringToRatio :: String -> Double stringToRatio "" = 0 stringToRatio s = let gen = mkStdGen $ sum $ map fromEnum s range = (\(a, b) -> b - a) $ genRange gen randomInt = foldr1 combine $ replicate 20 next combine f1 f2 g = let (_, g') = f1 g in f2 g' in fi (fst $ randomInt gen) / fi range Looks like it is supposed to simply generate a Double number between 0 and 1 - why such complicated approach was used instead of `uniformR` from System.Random? (also it seems that it is buggy and returns huge negative numbers, because `range = (\(a, b) -> b - a) $ genRange gen` is always -1. Best regards, Platon Pronko

Full-screen messes up tabs on google chrome
by Eyal Erez 04 Jul '21

04 Jul '21

Hi, I've started encountering a strange issue with xmonad and google chrome. After a full-screen chrome (e.g. by watching a youtube video and hitting "f"), the top part of chrome goes behind xmobar. If I make a layout change or open another window or app then it pops back into place, but this is a little bit annoying. I have some screenshots to try and illustrate this issue: During full-screen: https://ibb.co/z4hjC31 Before full-screen: https://ibb.co/TPPgRVS After full-screen: https://ibb.co/Y2vK1Xq Is it my setup that's the problem? Is there any way to fix it? My config file as available here: https://controlc.com/09924e80 Thank you -- There are 10 types of people, those who know binary and those who don't.

Hi, Not an answer to your question per se, but there's a patch [1] I made for the BSP layout that adds support for X.U.Minimize minimized windows. I've been using it for some time now, works perfectly.

Layout.Hiding: showing hidden in rofi and/or unhiding all
by Ramon Diaz-Uriarte 16 May '21

16 May '21

Hi, Is it possible to have hidden windows (from Layout.Hiding) be shown by rofi (rofi -show window)? I guess the answer is no [1]. In such a case, is it possible to unhide all hidden windows in all workspaces? (Probably not, either). Why this or something similar? Sometimes I have a window that I hide (say, emacs editing a file, unsaved) because something comes up. A while later I might not remember where that was (only "I have emacs somewhere opened editing file whatever"). I am forced to go through all of my workspaces popping the possible hidden windows. Maybe there is something much more sensible I am missing. (Note that using Layout.Minimize, instead of Layout.Hiding, is not really an option, since it interferes with BinarySpacePartition, which I use most of the time). Thanks, [1] That is why they are hidden :-) : "completely removes windows from the window set " from the documentation. -- Ramon Diaz-Uriarte Department of Biochemistry, Lab B-25 Facultad de Medicina Universidad Autónoma de Madrid Arzobispo Morcillo, 4 28029 Madrid Spain Phone: +34-91-497-2412 Email: rdiaz02(a)gmail.com ramon.diaz(a)iib.uam.es https://ligarto.org/rdiaz
