vim - 如何在 vim 宏中包含光标移动

Question

宏似乎没有考虑击键。在这种特殊情况下，我想编写一个注释掉一行的宏(在 latex 注释中以 % 开头)。以下是我使用的击键:

q +一个 +0 +w +我 +% +j +j +j +q

将宏分配给 a，转到行首，进入插入模式，放置百分号，退出插入模式，向下移动一行，并结束宏。然后我像这样使用宏

@ +一个

如果我有 4 行这样

1   In This life I have learned one thing █
2   It is pity incarnate of which I sing.
3   You have been told about the back of the crowd
4   And I repeat it, plenty loud.

使用宏三次导致这个

1   %%%In This life I have learned one thing █
2   It is pity incarnate of which I sing.
3   You have been told about the back of the crowd
4   And I repeat it, plenty loud.

当我想要的是这个

1   %In This life I have learned one thing █
2   %It is pity incarnate of which I sing.
3   %You have been told about the back of the crowd
4   And I repeat it, plenty loud.

更具体地说，我希望能够执行 30 + @ + a 来注释掉 30 行。我该怎么做？

Answer 1

我会去:

:.,+30 s/^\s*/&%

解释:

• .,+30 是从当前行到当前行 + 30 的范围(因此跨越 31 行)(:help range)
• s 是替换命令(:help :s)
• / 是模式分隔符
• ^\s* 是一个模式(:help pattern)，它对应于一行开头的任意数量的空格
• & 是插入匹配模式的替换特殊字符

其他方式:

ab©d (cursor on the c)
efgh
ijkl

键入CTRL-V、2j、I、你好、Esc，你会得到:

abhellocd
efhellogh
ijhellokl
