Vim搜索替换正则表达式+增量函数 [英] Vim search replace regex + incremental function

问题描述

目前，我一直在vim中试图找到一个搜索/替换oneliner，以用另一个+每个新迭代的增量替换一个数字=当它找到一个新的匹配时。

 < tspan 
x =938.91315
y =783.20563
 id =tspan13017
 style =font-weight：bold> Text1：< tspan>< tspan 
x =938.91315
y =833.20563
 id =tspan13019> Text2< / tspan>< tspan 
x =938.91315
y =883.20563
 id =tspan13021>✗Text3< / tspan> 
  

等。

要做的就是改变这个结果：

 < tspan 
x =938.91315
y = 200
 id =tspan13017
 style =font-weight：bold> Text1：< / tspan>< tspan 
x =938.91315 240
 id =tspan13019> Text2< / tspan>< tspan 
x =938.91315
y =280
 id =tspan13021>文本3< / TSPAN> 
  

等。

从zzapper中发现了最好的vim tips资源，但我无法理解它：

将yy转换为10,11,12：

：let i = 10 | 'a，'bg / Abc / s / yy / \ = i / | let i = i + 1

它的东西，我可以理解，应该在我的家庭VIM工作：

 ：let i = 300 | 327，$ smagic！ y = \[0-9] \ +。[0-9] \ + \！ \ =我！ g |让我=我+ 50 
  

但不知何故，它不循环，我得到的是：

 < tspan 
x =938.91315
 300 
 id =tspan13017
 style =font-weight：bold> Text1：< / tspan>< tspan 
x =938.91315
 300 
 id =tspan13019> tspan>< tspan 
x =938.91315
 300 
 id =tspan13021>✗Text3< / tspan> 
  

所以我在这里被严重卡住了。我找不出什么不起作用：

• 我改编了原始公式？


• 我的数据布局？


• 我的.vimrc？

我会尝试查找其他资源我自己，但在这种技巧，他们是非常罕见的，我发现，和zzapper技巧一样，并不总是与手册一起交付。 解决方案

$ p
$ b

 ：let i = 300 | g / \ m \< y = / s / \my =\zs\d\ + .\d\ + \ze/ \ = i / |让我+ = 50 
  

翻译：

• let i = 300 - 希望很明显


• g / \m \< y = / ... - 对于所有匹配 \m\ 的行，应用以下命令; 以下命令是 s /.../.../ |让... ;正则表达式：


  
  
  • \m - magicregexp
    
  • \< - 仅在字边界匹配
  
  
  
  • s / \my =\zs\d\ + .\d\ + \ze/ \ = i / - substitute;正则表达式：


    
    
    • \m - magicregexp
      
    • \ d\ + - 一位或多位数字
    
    
    • \ zs ... \ze - 仅替换这些点之间匹配的内容
    
    
    • \ = i - replace with表达式的值 i
    
    
    
    • let i +
    
    $ b

    I'm currently stuck in vim trying to find a search/replace oneliner to replace a number with another + increment for each new iteration = when it finds a new match.

    I'm working in xml svg code to batch process files Inkscape cannot process the text (plain svg multiline text bug).

    <tspan
           x="938.91315"
           y="783.20563"
           id="tspan13017"
           style="font-weight:bold">Text1:</tspan><tspan
           x="938.91315"
           y="833.20563"
           id="tspan13019">Text2</tspan><tspan
           x="938.91315"
           y="883.20563"
           id="tspan13021">✗Text3</tspan>
    

    etc.

    So what I want to do is to change that to this result:

    <tspan
           x="938.91315"
           y="200"
           id="tspan13017"
           style="font-weight:bold">Text1:</tspan><tspan
           x="938.91315"
           y="240"
           id="tspan13019">Text2</tspan><tspan
           x="938.91315"
           y="280"
           id="tspan13021">✗Text3</tspan>
    

    etc.

    So I duckducked and found the best vim tips resource from zzapper, but I cannot understand it:

    convert yy to 10,11,12 :

    :let i=10 | ’a,’bg/Abc/s/yy/\=i/ |let i=i+1

    I then adapted it to something I can understand and should work in my home vim:

    :let i=300 | 327,$ smagic ! y=\"[0-9]\+.[0-9]\+\" ! \=i ! g | let i=i+50
    

    But somehow it doesn't loop, all I get is that:

    <tspan
           x="938.91315"
           300
           id="tspan13017"
           style="font-weight:bold">Text1:</tspan><tspan
           x="938.91315"
           300
           id="tspan13019">Text2</tspan><tspan
           x="938.91315"
           300
           id="tspan13021">✗Text3</tspan>
    

    So here I'm seriously stuck. I cannot figure out what doesn't work :

    • My adaptation of the original formula ?
    • My data layout ?
    • My .vimrc ?

    I'll try to find other resources by myself, but on that kind of trick they are pretty rare I find, and like in zzapper tips, not always delivered with a manual.

    解决方案

    One way to fix it:

    :let i = 300 | g/\m\<y=/ s/\my="\zs\d\+.\d\+\ze"/\=i/ | let i += 50
    

    Translation:

    • let i = 300 - hopefully obvious
    • g/\m\<y=/ ... - for all lines matching \m\<y=, apply the following command; the "following command" is s/.../.../ | let ...; the regexp:
      • \m - "magic" regexp
      • \< - match only at word boundary
    • s/\my="\zs\d\+.\d\+\ze"/\=i/ - substitute; the regexp:
      • \m - "magic" regexp
      • \d\+ - one or more digits
      • \zs...\ze - replace only what is matched between these points
      • \=i - replace with the value of expression i
    • let i += 50 - hopefully obvious again.
