映射vim中的shift键 [英] mapping the shift key in vim

问题描述

在VIM中映射 Shift 键时遇到问题。我想要 Ctrl + L 与 Ctrl + Shift + / p>

所以我有这个

 for insert mode remap< c -l> to：
为ruby插入一个哈希火箭
插入一个 - > php 
为咖啡，shift键决定
 
函数！ SmartHash（...）
 let shift = a：0> 0 
 let ruby​​ =& ft =='ruby'
 let php =& ft =='php'
 let coffee =& ft =='coffee'
 
 if php 
 return\-> 
 end 
 
如果咖啡
返回班次？ \ => \ n：\  - > \\\

 end 
 
如果ruby 
返回\ =>
 end 
 
 return
 
 endfunction 
 
 imap< c-l> < c-r> = SmartHash（）< cr> 
 imap< C-S-L> < c-r> = SmartHash（1）< cr> 
  

...但它只是触发第二个映射，无论我是否有 Shift 按键。

根据接受的答案更新

 插入模式重映射到：
为ruby $ b插入哈希火箭$ b插入一个 - >对于php和coffeescript 
双击确实替代符号为php和coffescript 
功能！ SmartHash（...）
 let alt = a：0> 0 
 let ruby​​ =& ft =='ruby'
 let php =& ft =='php'
 let coffee =& ft =='coffee'
 
 if php || coffee 
 return alt？ \ => \ n：\  - > \\\

 end 
 
如果ruby 
返回\ =>
 end 
 
 return
 
 endfunction 
 
 imap< c-l> < c-r> = SmartHash（）< cr> 
 imap< c-l>< c-l> < c-r> = SmartHash（1）< cr> 
  

解决方案

由于键盘输入内部处理，这不幸的是今天是不可能的，即使在GVIM。这是一个已知的痛点，是关于vim_dev和#vim IRC频道的各种讨论的主题。

有些人（最重要的是Paul LeoNerd Evans）甚至对于支持此的终端中的控制台Vim），并且已经浮动了各种提议，cp。 http://groups.google.com/group/vim_dev/browse_thread/thread/626e83fa4588b32a/bfbcb22f37a8a1f8

但截至今天，没有补丁或志愿者尚未出现，虽然许多人已表示希望在未来的Vim 8主要版本中拥有这一点。 / p>

我通常通过使用 g 开始替换映射来解决这个问题，例如< C-l> 和 g ，但是在插入模式下不起作用。在你的情况下，用一点额外的逻辑，你可以在同一位置第二个< C-l> 改变以前插入的 - > 到 => ，以便您通过< C-l& code>，第二个通过< C-l>< C-1> 。

I'm having an issue when mapping the Shift key in VIM. I want Ctrl+L to behave differently than Ctrl+Shift+L

so I have this

" for insert mode remap <c-l> to:
" Insert a hash rocket  for ruby
" Insert a -> for php
" for coffee the shift key decides

function! SmartHash(...)
  let shift = a:0 > 0
  let ruby = &ft == 'ruby'
  let php = &ft == 'php'
  let coffee = &ft == 'coffee'

  if php
    return "\->"
  end

  if coffee
    return shift ? "\ =>\n" : "\ ->\n"
  end

  if ruby
    return "\ => "
  end

  return ""

endfunction

imap <c-l> <c-r>=SmartHash()<cr>
imap <C-S-L> <c-r>=SmartHash(1)<cr>

...but it's just triggering the second mapping whether I have the Shift key pressed or not.

Updated based on accepted answer

" for insert mode remap <c-l> to:
" Insert a hash rocket  for ruby
" Insert a -> for php and coffeescript
" double tapping does alternate symbol for php and coffescript
function! SmartHash(...)
  let alt = a:0 > 0
  let ruby = &ft == 'ruby'
  let php = &ft == 'php'
  let coffee = &ft == 'coffee'

  if php || coffee
    return alt ? "\ =>\n" : "\ ->\n"
  end

  if ruby
    return "\ => "
  end

  return ""

endfunction

imap <c-l> <c-r>=SmartHash()<cr>
imap <c-l><c-l> <c-r>=SmartHash(1)<cr>

解决方案

Due to the way that the keyboard input is handled internally, this unfortunately isn't possible today, even in GVIM. This is a known pain point, and the subject of various discussions on vim_dev and the #vim IRC channel.

Some people (foremost Paul LeoNerd Evans) want to fix that (even for console Vim in terminals that support this), and have floated various proposals, cp. http://groups.google.com/group/vim_dev/browse_thread/thread/626e83fa4588b32a/bfbcb22f37a8a1f8

But as of today, no patches or volunteers have yet come forward, though many have expressed a desire to have this in a future Vim 8 major release.

I usually work around this by starting my alternate mapping with g, e.g. <C-l> and g<C-l>, but that won't work in insert mode. In your case, with a little bit of additional logic, you could make a second <C-l> at the same position change the previously inserted -> to =>, so that you get the first alternative via <C-l>, and the second via <C-l><C-l>.
