PROFILE
Maëlle Salmon
Worked on the igraph/rigraph repository over three months, focusing on improving reliability, maintainability, and developer workflows for R-based graph analysis. Enhanced error handling by replacing deprecated stop() calls with cli_abort(), providing clearer user feedback and standardizing validation in layout functions. Addressed a bug in weighted graph detection logic, ensuring accurate analysis when weights are inconsistently defined. Automated release processes with a new R function, streamlined code by removing obsolete demo artifacts, and refactored core C interfaces for better organization and future performance gains. Utilized R, C, and Makefile, applying skills in code refactoring, package development, and release management.

Aug 1, 2025In 2025-08, delivered a focused bug fix in igraph/rigraph to improve reliability of graph analysis when weights are present but not uniformly defined. The change replaces the detection logic any(!is.na(weights)) with !all(is.na(weights)) to correctly identify the presence of non-NA weights, enhancing robustness across weighted graph operations. The work also included a readability-oriented commit to simplify the related code and documentation.
