在柔软件开发过程中，代码风格的一致性至关关键。它不仅有助于搞优良代码的可读性和可维护性，还能少许些团队之间的沟通本钱。对于在Ubuntu上开发C语言项目的开发者统一代码风格尤为关键。本文将详细介绍怎么在Ubuntu上统一C代码风格，并给实用的工具和步骤。

选择代码风格规范

在统一代码风格之前，先说说需要选择一个合适的代码风格规范。常见的C代码风格规范包括Google C++ Style Guide、LLVM Coding Standards等。以下以LLVM Coding Standards为例进行说明。

LLVM Coding Standards

LLVM Coding Standards给了一套详细的代码风格规范， 包括缩进、命名规则、注释等。

Language: C
BasedOnStyle: LLVM
IndentWidth: 4
TabWidth: 4
UseTab: Never
BreakBeforeBraces: Allman
ColumnLimit: 99

安装代码风格工具

为了方便统一代码风格，能安装一些代码风格工具。以下推荐几种常用的工具：

Clang-Tidy

Clang-Tidy是一个基于Clang的代码静态琢磨工具，它能检查代码风格是不是符合指定的规范。安装Clang-Tidy的方法如下：

sudo apt-get install clang-tidy

Checkstyle

Checkstyle是一个Java代码风格检查工具，它也能用于C代码。安装Checkstyle的方法如下：

sudo apt-get install checkstyle

配置代码风格检查

安装完代码风格工具后需要配置它们以检查代码风格。以下以Clang-Tidy为例进行说明。

在项目根目录下创建一个名为clang-tidy-checks.txt的文件，并添加以下内容：
