如何使用Eclipse使用行注释将Java从Allman重新格式化为K＆R？(How to reformat Java from Allman to K&R with line comments using Eclipse?)

我开始使用Allman风格进行编码，使用对齐的大括号：

void foobar() { if(foo) { bar(); } }

几十年后，我决定要增加屏幕空间; 此外，我的客户使用不匹配的大括号，因此很难从工作中来回切换到我的个人代码。 所以我想将现有的所有代码转换为K＆R：

void foobar() { if(foo) { bar(); } }

Eclipse 4.4有足够的代码格式化程序，如果我选择源代码树，我甚至可以批量格式化文件。 问题是，如果我有一个K＆R括号的行注释，Eclipse会拒绝将一个支架移动到一条线上，让我有一个大杂烩的编码风格：

void foobar() { if(foo) //if foo { bar(); } }

我怎么能告诉Eclipse移动支架，即使支架上的线有注释？

void foobar() { if(foo) { //if foo bar(); } }

I started out coding using the Allman style, with aligned braces:

void foobar() { if(foo) { bar(); } }

After decades I've decided I want that extra screen space; and besides, my client uses non-matched braces, so it's hard to switch back and forth from work to my personal code. So I want to convert all my existing code to K&R:

void foobar() { if(foo) { bar(); } }

Eclipse 4.4 has a sufficient code formatter, and if I select my source tree I can even format files in bulk. The problem is that if I have a line comment where a K&R brace would be, Eclipse will refuse to move the brace up a line, leaving me with a hodgepodge of coding styles:

void foobar() { if(foo) //if foo { bar(); } }

How can I tell Eclipse to move the brace up, even if there is a comment on the line where the brace goes?

void foobar() { if(foo) { //if foo bar(); } }

正则表达式替换文件; 更换

\)\s*(//.*)(\r?\n)(\s*)\{ 1 2 3

有：

) {\2\3 \1\2

更新（Garret Wilson）：经过大量实验，理想的正则表达式替换解决了所有变化并满足了我的需求：

^([^/]*(?:\)|\>|do|else|Exception|static|try))\s*(//.*)(\r?\n)(\s*)\{

替换为：

\1 { \2

A regular expression replacement over files; replace

\)\s*(//.*)(\r?\n)(\s*)\{ 1 2 3

with:

) {\2\3 \1\2

Update (Garret Wilson): After much experimentation, the ideal regular expression replacement that addressed all the variations and met my needs was:

^([^/]*(?:\)|\>|do|else|Exception|static|try))\s*(//.*)(\r?\n)(\s*)\{

replaced with:

\1 { \2
