Splint is a Clojure linter that examines coding style and the structure of expressions. Inspired by tools such as RuboCop and kibit, it helps developers follow established Clojure conventions and identify opportunities to simplify their code.
The application analyses source forms without executing them or expanding macros. Its rules concentrate on code shape rather than the meaning of variables or functions, making it complementary to tools such as clj-kondo and Eastwood.
Splint provides checks covering suspicious expressions, naming conventions, code complexity, performance and idiomatic Clojure style. Developers can enable or disable individual rules, adjust their behaviour and exclude particular files or expressions from analysis.
Some suggestions can be applied automatically, either directly or through an interactive confirmation process. The documentation warns that autocorrection can remove comments and unevaluated forms from modified expressions, so changes should be reviewed carefully.
This is free and open source software.
Key Features
- Linting rules grouped into style, naming, metrics, performance and correctness categories.
- Detects unnecessarily complex expressions and suggests more idiomatic alternatives.
- Checks naming conventions for functions, variables and other definitions.
- Measures code properties such as function length and parameter counts.
- Optional performance rules identify expressions with potentially more efficient alternatives.
- Configurable rules through .splint.edn, including rule-specific options.
- Exclude files using paths, glob patterns and regular expressions.
- Inline directives disable selected rules for individual expressions.
- Automatic correction for supported safe rules, with an interactive confirmation mode.
- Supports user-defined rules loaded from additional source files.
- Generates configuration files based on warnings found in an existing project.
- Plain text, Markdown, JSON and clj-kondo-compatible diagnostic output.
- Supports Clojure and ClojureScript source analysis.
- Parallel analysis of source files and configurable summary reporting.
