将 C 代码中的左大括号移到下一行? [英] Moving left brace in C code to the next line?

问题描述

我有几个 C 源文件需要更改一个特定的格式设置功能.在文件的某些部分，

I have several C source files that need to have one particular formatting feature changed. In some parts of the file,

if (x == NULL) {
    ...
}

需要改成

if (x == NULL)
{
    ...
}

我希望使用缩进"命令，但它太激进了.它想用所有选项更改整个文件.

I was hoping to use the "indent" command, but it's far too aggressive. It wants to change the entire file with all options.

我想我可以在 Perl 甚至 Sed 中做到这一点，但我对这两者的了解还不够清楚.

I suppose I can do this in Perl or maybe even Sed, but I don't know either well enough to figure that out.

推荐答案

看来今天是我的幸运日，看来我想通了:

Looks like today is my lucky day, as it appears I figured it out:

sed 's/^\([ ]*\)\(if (.* == NULL)\) {$/\1\2\n\1{/g' <filename>

有人可以确认这是正确的吗?

Can someone confirm that this is correct?
