SonarLint for VS Code v4.3

SonarLint for VS Code v4.3 enhances the combined power of SonarLint and SonarQube while streamlining the setup process.


Now, a one-click connection setup and project binding option will be shown to a SonarLint for VS Code developer utilizing the SonarQube “Open in IDE” button to investigate an issue directly in their VS Code IDE. This functionality, which requires SonarQube v10.4, assists developers in rapidly examining and resolving issues using SonarLint directly in their VS Code IDE.


Plus, with their SonarLint for VS Code v4.3 connected to SonarQube v10.4, developers can now detect custom secrets in their code, directly in their IDE. Using custom rules based on secret patterns defined in SonarQube allows developers to spot secrets before they can be leaked into repositories. (Requires SonarQube Enterprise or Data Center Edition).


Also, when using connected mode to SonarCloud or SonarQube v10.4, it is now possible to mark an issue as “Accepted”. This results in the unresolved issue becoming part of the project’s technical debt.

SonarLint for VS Code v4.0

SonarLint for VS Code v4.0 brings initial support for C# analysis, plus further benefits when using SonarLint in connected mode to SonarCloud and SonarQube.


We are excited to announce support for C# analysis, available both in standalone or connected mode to SonarQube and SonarCloud. The most requested feature in our roadmap this initial support is designed to help those developing .NET applications to create clean code.

With SonarQube v10.3, you can now open any issue you’re investigating in SonarQube directly into the IDE, with just a click of a button, thanks to connected mode. This allows you to leverage SonarLint’s dataflow navigation, rule descriptions, and quick fixes for efficient issue investigation and resolution.


Using connected mode to SonarCloud, any issue or status change (e.g. Won’t Fix, False Positive) made in SonarCloud will be instantly synchronized to your IDE, ensuring you can focus on relevant issues.


Plus:

  • 6 Java rules dedicated to the Spring framework
  • 5 Python rules 2 for the Pandas library
  • Many new JavaScript and TypeScript rules for React


Lastly, please be advised that we are raising the minimum required Java runtime version to 17. See here for more details.

SonarLint for VS Code v3.22

In SonarLint for VS Code v3.2, we deliver a new feature supporting the Sonar Clean as You Code methodology. Plus we have extra rules to detect secrets directly in the IDE, the option to configure file or directory exclusions, and new rules for Data Scientists and Dockerfiles!


SonarLint is pairing up with SonarQube and SonarCloud to deliver the “Focus on new code” feature. Enabled, this empowers you to focus only on issues in your new code (ie code that has been added or changed, according to your new code definition.) Supporting the Sonar Clean as You Code approach, this powerful feature is available when SonarLint is working together with SonarQube or SonarCloud in connected mode. Learn how here.


In addition, we have incorporated 42 new rules to detect secrets (API tokens, passwords) within your Cloud applications. This enables the immediate detection of secrets in your code as you add or copy/paste them, before you commit or push the code into a repository. This proactive approach not only boosts confidence in your code but also minimizes exposure.

This latest addition brings the total to 100 different types of secrets spanning 60 cloud providers.


Plus:


  • An option to configure file or directory exclusions for SonarLint analysis to avoid scanning generated or third-party code. See how here.
  • 8 new Python rules (and 3 quick fixes) to help you write clean scientific code using NumPy
  • 12 new rules to write intentional and consistent Dockerfiles

SonarLint for VS Code v3.21

In SonarLint for VS Code v3.21, we introduce the adoption of Clean Code attributes to categorize issues, enhanced secret pattern detection, and improved teamwork features together with SonarQube.


Firstly, we have made various product changes in alignment with our Clean Code vision. For each issue raised in your code, SonarLint will report the Clean Code attribute and software qualities impacted.


In addition, and leveraging a new Sonar open-source secret detection engine, this version delivers a powerful approach to identifying potential security vulnerabilities related to secrets (tokens, passwords, API keys). SonarLint can now detect secrets for an additional 22 popular cloud applications and providers.


On top of this, for SonarQube 10.2 users, we’ve added the capability to change the status of issues you will not fix in code that has yet to be analyzed by SonarQube.
