本文介绍了一款强大的代码格式化工具Uncrustify，它能自动调整代码风格，包括对齐符号、变量定义、注释、空格等，支持多种编程语言，并提供高度可配置选项。

Ident code, aligning on parens, assignments, etc
Align on '=' and variable definitions
Align structure initializers
Align #define stuff
Align backslash-newline stuff
Reformat comments (a little bit)
Fix inter-character spacing
Add or remove parens on return statements
Add or remove braces on single-statement if/do/while/for statements
Supports embedded SQL 'EXEC SQL' stuff
Highly configurable - 385 configurable options as of version 0.56
