Sonarlint Code Analysis Tool for C, C++, C#, Java and more

Sonarlint code analysis tool is a top-rated code analysis tool that detects code quality and security issues on the fly. The key benefit of using Sonarlint to detect bugs is applying thousands of rules that notice common mistakes in our code. It works like a spell-checker, where issues are seen on the fly and reported as we write the code. Sonarlint precisely pinpoints where the problem is and provides recommendations on how to fix it.

Sonarlint Code Analysis Tool

SonarLint is a code analysis tool that helps developers to improve the quality of their code by identifying and fixing issues before they reach production. It is a plugin for various IDEs (Integrated Development Environments) such as Visual Studio, Eclipse, and IntelliJ IDEA, that uses the same rules and engine as the popular static code analysis tool, SonarQube.

SonarLint provides real-time feedback on code quality issues as the developer writes the code, such as bugs, security vulnerabilities, and code smells. This allows developers to address issues early in the development process, reducing the cost and effort required to fix them later on.

SonarLint uses a set of predefined rules to analyze the code and it can also be configured to use custom rules. It also supports multiple languages, including Java, C#, JavaScript, and Python.

Integrating SonarLint into the developer’s workflow helps to ensure that the code is of high quality, maintainable and secure and improves the developer’s productivity.

Sonarlint provides rich document sets that help us understand the issues better and discover the coding best practices. Sonarlint is multilingual and supports many languages. After installing the Sonarlint plugin, a startup notification will ask for installing support for additional languages. You can do this any time from the Sonarlint menu option.

SonarLint code analysis tool supports a wide range of programming languages, including Java, C#, JavaScript, and Python. It analyzes the code locally, and it does not require an internet connection to work. The tool helps developers to identify and fix issues before they are committed to the source control, thus improving the code quality and saving time for debugging and testing.

It’s important to note that SonarLint is not a replacement for testing, it is a tool to help you catch issues early and it provides additional information that can help to improve your codebase.

Sonarlint is an easy-to-use plugin where it doesn’t need any configuration after the installation.
Full solution analysis can be done by additional configuration in the visual studio.
Sonarlint is integrated with the Microsoft Code Analysis framework. The rules can be fine-tuned in the .ruleset file.
Sonarlint plugin can be installed or supported by the below list of development IDEs

  • Eclipse
  • IntelliJ IDEA
  • Visual Studio
  • VS Code

Sonarlint Rules:

Sonarlint code analysis tool is fully automated, which makes your code reliable by avoiding bugs and undefined behavior. It makes your code secure by avoiding breaches or attacks. Also, it makes your code maintainable through code updates.

The Sonarlint defined a set of rules for each programming language to validate the target code and provide necessary fixes if there are any issues. You can see all rules by following the This is the official document repository of Sonarlint, which covers the ruleset of all the languages. The document explains each rule in-depth by providing problem definitions and associated solutions with code snippets. This is one of the good resources for developers to understand how to code better.

Supported Languages:

Sonarlint code analysis tool covers most of the popular programming languages listed below.
ABAP, Apex, C, C++, COBAL, C#, CSS, Flex, Go, HTML, Java, JavaScript, Kotlin, Objective-C, PHP, PL/I, PL/SQL, Python, RPG, Ruby, Scala, Swift, TypeScript, T-SQL, VN.NET, VB6, XML.

Download location:

Solarlint code analysis tool can be downloaded from its official download location.
Sonarlint is currently supported for three major Visual Studio versions 2015, 2017, and 2019.

Sonarlint reports issues on the files that we are editing. The Output panel shows the output from Sonarlint as well. You can increase the verbosity in the Visual Studio options under the Sonarlint menu item.
