问题描述

有时我想查看某个函数在文件或代码块中被调用了多少次.你是怎样做的?我使用的是 Vim 7.2.

Sometimes I want to see how many times a certain function is called in a file or a code block. How do you do that? I am using Vim 7.2.

我想你必须使用 !wc 或类似的东西.

推荐答案

要计算某个模式出现的次数，请使用:

For counting the number of times some pattern occurs, use:

:%s/pattern//gn

'n' 标志计算出现的次数，而不对文档进行任何更改.

The 'n' flag count the number of occurrences without doing any change to the document.

要计算总字数，您有多种选择.

For counting the total number of words, you have several options.

如果您想作为外部命令运行:

If you want to run as an external command:

:!wc -w %

如果你想在 VIM 中运行它:

If you want to run it inside VIM:

:w !wc -w
