Spotless is a multi-language formatting orchestrator and Gradle plugin that automates code styling across various programming languages within a single build pipeline. It functions as a coordinator for multiple third-party formatters, a code style linting tool, and a system for inserting and updating standardized license headers. The project distinguishes itself through git-integrated style enforcement, using pre-push hooks and git references to apply formatting only to modified files or lines. It supports shared build configurations, allowing formatting rules to be distributed and loaded acr
Prettier is an opinionated code formatter that parses source code and reprints it from scratch to enforce a consistent, project-wide visual style. By transforming code into an abstract syntax tree and applying a recursive document printing process, it eliminates manual style debates and ensures that all source files adhere to a unified appearance. The project is distinguished by its extensible, plugin-based architecture, which decouples language-specific parsing logic from the core engine. This modular design allows for uniform style enforcement across diverse programming languages and comple
rustfmt is a Rust code formatter that operates as a Cargo subcommand, applying consistent formatting to Rust source files according to official style guidelines. It parses source code into a syntax tree, applies formatting rules to tree nodes, and pretty-prints the result back to text, with support for TOML-driven configuration that allows per-project style customization. The formatter is edition-aware, automatically selecting formatting rules based on the Rust edition specified in the project, and supports a style edition override that decouples formatting rules from the Rust edition used fo
Stylelint is a static code analysis tool and linter for CSS and style-like languages. It identifies errors, enforces coding conventions, and operates as a PostCSS plugin to validate stylesheets during build pipelines. The project distinguishes itself through support for non-standard syntaxes, including preprocessor parsing for SCSS and Less, and the ability to extract and lint embedded styles from JavaScript, HTML, and template literals. It features an automated fixing system that programmatically corrects repairable styling violations to ensure consistency. The system provides a plugin arch
