Overview of linters

A linter is a software tool that analyzes codebase for bugs, errors, and other mistakes that impact its quality and can cause problems. Basically, each Qodana linter is associated with a specific programming language and helps you:

• Detect anomalous code and probable bugs

• Eliminate dead code

• Highlight spelling problems

• Improve overall code structure

• Introduce coding best practices

• Check third-party license compatibility. This feature is available in several linters

• Upload analysis reports to Qodana Cloud

Currently, several linters provide inspections for several programming languages.

* Using tags, you can pull pre-configured Qodana images:

• For the Qodana for C/C++ linter, in the -clangXX tag specify the Clang-Tidy version from 15 to 18.

• For the Qodana for Ruby linter, in the -ruby3.X tag specify the Ruby version from 3.1 to 3.4.

Using the -privileged tag, you can run Qodana in the privileged mode to execute commands that require root access. In this case, Qodana comes with a default qodana user that possesses root privileges and does not require a password.
