The dependency graph (DG) of a software project offers valuable insights for identifying its key components and, hence has been leveraged in numerous studies. Nevertheless, there is a lack of reusable tools for DG extraction. Existing tools are either outdated and difficult to configure, or fail to provide accurate analysis. However, Integrated Development Environments (IDEs) are designed to address the above issues. This study introduces RefExpo, a reusable DG extraction tool that supports multiple languages, such as Java, Python, and JavaScript. RefExpo is a plugin based on IntelliJ which is a well-maintained and reputed IDE. In addition, we compile an initial version of our dataset consisting of 20 Java and Python projects. We evaluated RefExpo’s validity at two levels: specific language features and comparisons against other existing tools, which we refer to as the micro and macro levels. Our evaluation shows RefExpo achieving 92% and 100% recall on micro test suites Judge and PyCG for Python and Java, respectively. In macro-level experiments, RefExpo outperformed existing tools by at least 31% and 7% in finding unique and shared results (non-overlapping and overlapping with other tools). The installable version of RefExpo is available on the IntelliJ marketplace. Additionally, a short video describing its functionality is available on YouTube.
