PMD
Enhance your code quality with PMD.
PMD is a source code analyzer that finds unused variables, empty catch blocks, and unnecessary object creation.
Overview
PMD is an extensible multilanguage static code analyzer that identifies common programming flaws such as unused variables, empty catch blocks, and unnecessary object creation. It primarily focuses on Java and Apex while supporting 16 additional languages.
Key Features
- Over 400 built-in rules
- Support for multiple languages including Java, JavaScript, and Apex
- Custom rule creation
- Utilizes JavaCC and Antlr for parsing
- Abstract syntax tree (AST) analysis
Use Cases
PMD is ideal for developers looking to maintain clean code and improve software quality through static analysis. It can be used in continuous integration pipelines to automate code reviews.
How It Works
PMD parses source files into abstract syntax trees (AST) and applies rules to detect violations. Rules can be defined in Java or XPath queries, allowing for flexibility in customization.
Integrations
PMD can be integrated into various development environments and CI/CD tools, enhancing the code review process.
Security & Compliance
By identifying potential vulnerabilities and code smells, PMD helps ensure compliance with coding standards and security best practices.
Ideal For
PMD is suitable for software developers, teams focused on code quality, and organizations implementing coding standards across projects.
