使用程序员dvorak键盘布局切换xmonad中的工作区（移位的数字） [英] Switching workspaces in xmonad using programmer dvorak keyboard layout (shifted numbers)

问题描述

好吧，我实际上并没有使用Dvorak，而是 Neo2 ，但由于我使用的是矩阵式键盘（< a strong href =http://www.trulyergonomic.com/ =noreferrer>真正符合人体工程学的）我也改变了数字。

因此，我的 xmonad.hs 中的这个构造不符合人体工程学的设计：

   -  mod- [1..9]，切换到工作区N 
  -  mod-shift- [1..9]，将客户端移动到工作区N 
  - 
 [（（m。| .modMask，k），windows $ fi）
 | （w，shift，shiftMask），（f，m） -  [（w.gift_view，0），（w，shift，shiftMask） ] 
  

我想改变它，以便能够访问工作区1到9钥匙2到0。

我怎么能达到目的？我已经尝试将第三行改为

  | （i，k）←zip（XMonad.workspaces conf）[xK_2 .. xK_0] 
  

但之后我无法访问第9个工作区。我该如何改变这个？一个简短的解释会很好，所以要学习一些关于这个构造的知识（我在很多年前学过Haskell，并且忘记了它的大部分内容）。 解决方案

您的问题是 xK_2 大于 xK_0 ，所以列表 [xK_2 .. xK_0] 为空：

  Prelude XMonad> xK_2 
 50 
 Prelude XMonad> xK_0 
 48 
 Prelude XMonad> [xK_2 .. xK_0] 
 [] 
  

您需要稍长一些列表比。至少有两种合理的方法可以做到这一点;一个是你自己手动指定所有的键：

  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] 
  

我可能会用到的有点短：

  Prelude XMonad> [xK_2 .. xK_9] ++ [xK_0] 
 [50,51,52,53,54,55,56,57,48] 
  

如果它是更大表达式的一部分，请记住添加一些括号。

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.

Therefore this construction in my xmonad.hs does not work ergonomically:

-- 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.

How could I achive that? I have tried to change the third line to

    | (i, k) <- zip (XMonad.workspaces conf) [xK_2 .. xK_0]

but then I could not access the 9th workspace. How do I have to change this? A short explanition would be nice, so to learn something about this construction (I learned Haskell many years ago and forgot most of it).

解决方案

Your problem is that xK_2 is bigger than xK_0, so the list [xK_2 .. xK_0] is empty:

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. There's at least two reasonable ways to do this; one is to just specify all of keys yourself manually:

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:

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.
