Uncrustify is a highly configurable source code beautifier for C, C++, C#, Objective-C, D, Java, Pawn, and Vala. It reformats code by adjusting spacing, newlines, indentation, alignment, and braces according to hundreds of configurable options.

Use cases

• format C++ code to a consistent style
• enforce code style across a C-like codebase
• add or remove braces on single-statement if/for/while blocks
• align variable definitions and struct initializers
• reformat Java indentation and spacing
• normalize whitespace before parens and around operators
• integrate a code formatter into CI to check style

When to choose

• you need fine-grained control over formatting rules beyond what clang-format offers
• your project uses C, C++, C#, Objective-C, D, Java, Pawn, or Vala
• you want to enforce a custom house style with hundreds of tweakable options

When to avoid

• you want zero-configuration opinionated formatting out of the box
• your language is not C-like (e.g., Python, Go, Rust)
• you prefer a formatter with a small, simple option set
