在Vim中选择整个函数定义 [英] Selecting entire function definition in Vim

问题描述

我现在一直在尝试Vim进行任何文本编辑工作。例如，如果我有这样的功能：

  void helloworlds（int num）
 {
 int n; （n = 0; n  printf（Hello World！\\\
）; 
 
} 
} 
  

我将如何删除整个定义，包括函数名称？

解决方案

在Vim中很常见，有很多方法！

请注意，前两个解决方案取决于没有空白行。

• 如果您的光标是在具有函数名称的行上，请尝试 d } 。它将删除所有到下一个块（即你的函数体）。




• 在函数体中， d a p 会删除'段落'。

一 } 。 （如果你喜欢这种语法，我推荐Tim Pope的奇妙的 surround.vim ，它增加了更多的功能类似的感觉）。


• 你也可以尝试使用正则表达式来删除，直到下一个最左边的缩进的大括号： d > ] 和 [ [移至下一个/上一个第一列大括号（相当于使用 / 和？与前面提到的那个正则表达式组合在一起。与 d 在 Python模式等插件中，这些运算符被重新定义为，以表示您正在寻找的内容：从函数移动到函数。

如何删除如果您位于标题/名称或块之前的行， d 包含的标题

一个 } 应该可以做到。

如果你在一个块下面，你也可以利用这个方便的'偏移'功能的Vim搜索。 d ^ { - ？ 1 将在第一列开头大括号首次出现之前向后删除一行。输入这个命令有点棘手。也许你可以制作一个< leader> 快捷方式。

插件

我在Vim中做的C编程并不多，但肯定有插件可以帮助解决这样的问题。试试 Vim脚本或他们的 GitHub上的镜像。

I've been trying Vim for any text editing work for almost a week now. I want to know the fastest way to select a C function definition.

For example, if I have a function like this:

void helloworlds( int num )
{
    int n;
    for ( n = 0; n < num; ++n ) {
        printf( "Hello World!\n" );
    }
}

How would I be able to delete the whole definition including the function name?

解决方案

As is common in Vim, there are a bunch of ways!

Note that the first two solutions depend on an absence of blank lines.

• If your cursor is on the line with the function name, try d}. It will delete everything to the next block (i.e. your function body).

• Within the function body itself, dap will delete the 'paragraph'.

• You can delete a curly brace block with da}. (If you like this syntax, I recommend Tim Pope's fantastic surround.vim, which adds more features with a similar feel).

• You could also try using regular expressions to delete until the next far left-indented closing curly brace: d/^}Enter

• ]] and [[ move to the next/previous first-column curly brace (equivalent to using / and ? with that regex I mentioned above. Combine with the d motion, and you acheive the same effect. In addons like Python-mode, these operators are redefined to mean exactly what you're looking for: move from function to function.

How to delete the whole block, header included

If you're on the header/name, or the line before the block, da} should do the trick.

If you're below a block, you can also make use of the handy 'offset' feature of a Vim search. d?^{?-1 will delete backwards to one line before the first occurrence of a first-column opening curly brace. This command's a bit tricky to type. Maybe you could make a <leader> shortcut out of it.

Plugins

I don't do much C programming in Vim, but there are surely plugins to help with such a thing. Try Vim Scripts or their mirror at GitHub.
