SonarSource provides a static code analyzer for PL/I projects. Based on our own technology, SonarPLI analyzes code and find code smells, bugs and security vulnerabilities. As for any product we develop at SonarSource, it was built on the following principles: depth, accuracy and speed.
SonarPLI covers some of the well-established quality standards. The SonarPLI capability is available in Compuware Topaz and IBM IDz for developers (SonarLint) as well as throughout the development chain for automated code review with self-hosted SonarQube or on-line SonarCloud.
SonarPLI provides the ability to write custom rules.
