在 Vim 中用递增的值搜索和替换 [英] Search and Replace with incremented values in Vim

问题描述

假设我写了一个简单的 CSS 规则，如下所示:

Lets say I wrote a simple CSS rule like this:

.star_10 {
  background: url(stars.png) no-repeat 0 0;
}

我需要 10 个，所以我复制了 9 次.

And I need 10, so I copied it 9 times.

.star_10 {
  background: url(stars.png) no-repeat 0 0;
}
.star_10 {
  background: url(stars.png) no-repeat 0 0;
}
.star_10 {
  background: url(stars.png) no-repeat 0 0;
}
.star_10 {
  background: url(stars.png) no-repeat 0 0;
}
.star_10 {
  background: url(stars.png) no-repeat 0 0;
}

等

现在我想用递增的值更改 star_10 和 0 0 如下所示:

Now I want to change the star_10 and 0 0 with incremented values so it looks like this:

.star_10 {
  background: url(stars.png) no-repeat 0 0;
}
.star_9 {
  background: url(stars.png) no-repeat 0 -18px;
}
.star_8 {
  background: url(stars.png) no-repeat 0 -36px;
}
.star_7 {
  background: url(stars.png) no-repeat 0 -54px;
}

等等...

那么我如何搜索/替换每个实例，进行计算并编写它?

So how can I search/replace every instance, do a calculation and write it?

推荐答案

您可以使用宏轻松完成.假设您只有这个:

You can do it easily with a macro. Lets say you have only this:

.star_10 {
  background: url(stars.png) no-repeat 0 0;
}

将光标放在第一个点上(在 .star10 中)并在正常模式下键入以下内容:

Place your cursor over the first dot (in .star10) and type the following in normal mode:

qa3yy3jp^Xjt;18^Xk0q

说明:

1. qa 将在寄存器a"中开始录制宏.
2. 3yy 将拉取(复制)以下 3 行.
3. 3j 会将光标向下放置 3 行.
4. p 将粘贴过去的文本.
5. ^X (ctrl+x) 会递减星级.
6. j 会将光标向下移动一行.
7. t; 会将光标置于当前行中的下一个 ; 之前.
8. 18^X 将背景的 y 坐标减少 18；
9. k 将光标放在一行，
10. 0 将光标置于行首.
11. q 将完成宏录制.

1. qa will start a macro recording in register "a".
2. 3yy will yank (copy) the following 3 lines.
3. 3j will place the cursor 3 lines down.
4. p will paste the past yanked text.
5. ^X (ctrl+x) will decrement the star class number.
6. j will place your cursor one line down.
7. t; will place your cursor before the next ; in the current line.
8. 18^X will decrement the y coordinate of backround by 18;
9. k will put the cursor one line up,
10. 0 will put the cursor at the beggining of the line.
11. q will finish the macro recording.

在那之后，你可能会有这样的事情.

After that, you may have something like this.

.star_10 {
  background: url(stars.png) no-repeat 0 0;
}

.star_9 {
  background: url(stars.png) no-repeat 0 -18;
}

就是这样.只需将光标放在 .star_9 上的点上，然后按 8@a 再执行 8 次寄存器 a 中记录的宏.

That's it. Just place your cursor at the dot on .star_9 and press 8@a to execute the macro recorded in register a eight more times.
