变化括号现在的位置与SED [英] change braces postion with sed

问题描述

我有多个来源$ C ​​$ CS中括号都是这样

I have multiple source codes in which braces are like this

function()
{
    if(...)
    {
        ...
    }
    else
    {
        ...
    }
}

我想使它看起来像这样：

I would like to make it look like this:

function() {
    if(...) {
        ...
    }
    else {
        ...
    }
}

我已经尝试了一些技巧与 SED 命令，但我无法弄清楚如何得到它的正常工作。这里是我的最新尝试：

I've tried some tricks with the sed command, but I can't figure out how to get it working properly. Here is my latest try:

sed ":a; N; $!ba; s/\n{/ {/g" myfile

感谢您的帮助！

编辑 -

我设法把这个工作与命令：

I managed to have this working with that command:

sed "N;/\n *{/s// {/;P;D"

像往常一样与 SED ，我十分不明白为什么它的工作原理，但它确实。

As usual with sed, I quite don't understand why it works, but it does.
