[英]Switching workspaces in xmonad using programmer dvorak keyboard layout (shifted numbers)
Well, I am not using Dvorak actually but Neo2 , but as I am using a matrix type keyboard ( Truly Ergonomic ) I have also shifted the numbers. 好吧,我实际上并没有使用Dvorak而是使用Neo2 ,但是当我使用矩阵型键盘( Truly Ergonomic )时, 我也改变了数字。
Therefore this construction in my xmonad.hs
does not work ergonomically: 因此,我的xmonad.hs
中的这种构造不符合人体工程学:
-- mod-[1..9], Switch to workspace N
-- mod-shift-[1..9], Move client to workspace N
--
[((m .|. modMask, k), windows $ f i)
| (i, k) <- zip (XMonad.workspaces conf) [xK_1 .. xK_9]
, (f, m) <- [(W.greedyView, 0), (W.shift, shiftMask)]
I want to change that, to be able to access the workspaces 1 to 9 with the keys 2 to 0. 我想改变这一点,以便能够使用键2到0访问工作区1到9。
How could I achive that? 我怎么能这样做? I have tried to change the third line to 我试图改变第三行
| (i, k) <- zip (XMonad.workspaces conf) [xK_2 .. xK_0]
but then I could not access the 9th workspace. 但后来我无法访问第9个工作区。 How do I have to change this? 我该如何改变这个? A short explanition would be nice, so to learn something about this construction (I learned Haskell many years ago and forgot most of it). 一个简短的解释会很好,所以要了解一下这个结构(我多年前学过Haskell而忘记了大部分内容)。
Your problem is that xK_2
is bigger than xK_0
, so the list [xK_2 .. xK_0]
is empty: 您的问题是xK_2
大于xK_0
,因此列表[xK_2 .. xK_0]
为空:
Prelude XMonad> xK_2
50
Prelude XMonad> xK_0
48
Prelude XMonad> [xK_2 .. xK_0]
[]
You'll want to use a bit longer list than that. 你会想要使用比这更长的列表。 There's at least two reasonable ways to do this; 至少有两种合理的方法可以做到这一点; one is to just specify all of keys yourself manually: 一种是自己手动指定所有键:
Prelude XMonad> [xK_2, xK_3, xK_4, xK_5, xK_6, xK_7, xK_8, xK_9, xK_0]
[50,51,52,53,54,55,56,57,48]
What I would probably use is a bit shorter: 我可能会使用的更短一点:
Prelude XMonad> [xK_2 .. xK_9] ++ [xK_0]
[50,51,52,53,54,55,56,57,48]
Remember to add some parentheses if it's part of a bigger expression. 如果它是更大表达式的一部分,请记住添加一些括号。
