The Infomap repository provides a software implementation of the Infomap algorithm for multi-level network clustering based on the map equation. It offers a standalone command-line interface and language bindings for Python, R, and JavaScript, enabling users to detect community structure in various network types (including weighted, directed, bipartite, multilayer, and higher-order networks). The core algorithm is implemented in C++ with a modular design separating optimization, I/O, configuration, and output handling. The architecture emphasizes reusability and extensibility, featuring a parameter catalog system for managing options, a console utility for formatted terminal output, and safe string conversion utilities. The system supports multiple input and output formats, integrates with popular graph libraries (NetworkX, igraph), and includes advanced features such as entropy correction, teleportation, and regularization. Comprehensive test suites, benchmarking tools, and documentation ensure reliability and ease of use across different platforms and programming languages. While the repository includes example networks and tutorial notebooks for demonstration and validation, its primary focus is delivering a robust, reusable tool for network analysis rather than conducting specific data research. The codebase is actively maintained with continuous integration, regular releases, and cross-language binding consistency checks.
