astyle

相信大家都了解Coding Style對於程式的可讀性有重大的影響，

然而可能沒有幾個人能真正的遵守好一個固定的Coding Style。

Astyle 是一個跨平台的Coding Style Adjusting軟體，支援 C, C++, C#, and Java

它可以幫助各位輕易的把程式碼轉變成你所想要的格式。

它 default 支援 ANSI, GNU, K&R, Linux和 Java 的Code style

當然，你可以自行定義自已喜好的 Coding style

以下是我個人的使用例子

我個人喜好使用 java (--style=java) 的 coding style，而且我不希望做完縮排後產生備份檔 (-n)

我的使用方法就變成了

astyle --style=java –n …

如果我希望 default 就是我的喜好格式，

可以把我的 config 放入 ~/.astylerc

Example:

> cat ~/.astylerc

--style=java –n

Hello

Hello All,
Welcome to my Blog!
This is a place I put my notes of my interests.
I may write in chinese or English.

I enjoy linux (kernel) programming and playing ocarina a lot.
And therefore I named this blob as "Linux & Ocarina",
though I might put something else here.
