Per Tillisch, Tooling Team SW Engineer at Arduino, has published a new article on the official Arduino blog detailing a new tool to check Arduino projects for common problems. Arduino Lint runs over 175 checks on your sketches, libraries, and boards platforms which cover specification compliance, Library Manager submission requirements, and best practices.
What is Arduino Lint?
Arduino Lint is an easy-to-use, yet powerful, command line tool, focusing on the structure, metadata, and configuration of Arduino projects, rather than the code itself. This tool is designed to help developers ensure that their projects adhere to the best practices and standards set by the Arduino community. It is available to install now via GitHub, making it accessible for developers worldwide.
The tool performs a comprehensive analysis of your project, checking for common issues that could cause problems during development or deployment. By running over 175 checks, Arduino Lint helps you catch potential issues early, saving you time and effort in the long run. These checks include verifying the structure of your project, ensuring that metadata is correctly formatted, and checking that configuration files meet the required standards.
How to Install and Use Arduino Lint
Installing Arduino Lint is straightforward. The script requires `sh`, which is always available on Linux and macOS. However, `sh` is not available by default on Windows. To run the script on Windows, you need to install Git for Windows and then run it from Git Bash. Pre-built binaries for all the supported platforms are available, making the installation process even more convenient.
Once Arduino Lint is installed, you only need to open a terminal at your project folder and run the command: `arduino-lint`. This command will initiate the tool, and it will begin checking your project for any issues. The results are displayed in the terminal, providing you with a detailed report of any problems found and suggestions for how to fix them.

Benefits of Using Arduino Lint
Using Arduino Lint offers several benefits for developers. Firstly, it helps maintain a high standard of quality for your projects by ensuring that they comply with Arduino’s specifications and best practices. This can be particularly useful for developers who are submitting their libraries to the Arduino Library Manager, as it helps ensure that their submissions meet the necessary requirements.
Additionally, Arduino Lint can save you time and effort by catching potential issues early in the development process. By identifying problems before they become more significant, you can address them quickly and avoid the frustration of debugging complex issues later on. This can lead to a more efficient development process and a more stable final product.
Furthermore, Arduino Lint is a valuable tool for collaborative projects. By ensuring that all team members adhere to the same standards and best practices, you can improve the overall quality and consistency of your codebase. This can make it easier to manage and maintain your project over time, particularly as it grows in size and complexity.
In conclusion, Arduino Lint is a powerful and easy-to-use tool that can help developers ensure their projects adhere to Arduino’s best practices and standards. By running over 175 checks on your sketches, libraries, and boards platforms, it helps catch potential issues early, saving you time and effort in the long run. Whether you’re a solo developer or part of a larger team, Arduino Lint can help you maintain a high standard of quality for your projects and improve your overall development process.
Once Arduino Lint is installed, you only need to open a terminal at your project folder and run the command: arduino-lint.
