cmakelint
Static code checker for CMake files
Decision gist · record as of 2026-08-14
Yes, if you maintain CMake projects and want automated style checking. The tool is lightweight, dependency-free, and permissively licensed. The dormant maintenance status is a minor concern for new features, but the stable codebase and lack of known vulnerabilities make it safe for ongoing use in established workflows.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Low install friction with no runtime dependencies.
- Maintenance is dormant—last release was in May 2024—but the repository remains active and the package is marked Production/Stable.

What it is and what it does
cmakelint is a static code checker for CMake files that enforces style and quality rules. It parses CMakeLists.txt and related CMake scripts, then reports violations across multiple categories: syntax errors, whitespace issues (indentation, tabs, line endings, extra whitespace), readability problems (mixed case, logic clarity), package consistency, and filename conventions. The tool is configured via command-line filters or a .cmakelintrc configuration file, and supports inline directives within CMake files to override rules on a per-file basis.
It integrates into development workflows as a standalone command-line tool or as a pre-commit hook. With no runtime dependencies and a pure-Python wheel distribution, installation is straightforward. The package has been stable since its early releases and remains in production use, though active development has slowed.
Use it for
- Enforce consistent CMake style across a project before committing code.
- Integrate CMake linting into CI/CD pipelines to catch style violations early.
- Set up pre-commit hooks to automatically check CMakeLists.txt files on each commit.
- Audit existing CMake codebases for whitespace and naming convention violations.
- Configure project-specific CMake rules via .cmakelintrc to match team standards.
