PROFILE
Esteban Dugueperoux
Esteban Duguéperoux modernized and modularized the build system for the IfcOpenShell/IfcOpenShell repository, focusing on cross-platform reliability and maintainability. Over five months, he refactored CMake configurations to enable per-component builds, streamlined dependency management, and standardized the use of C++17 across all configurations. His work included integrating HDF5 and OpenCOLLADA support, optimizing library linkage, and improving CI validation to ensure reproducible builds. By consolidating build logic and enhancing modularity with C++, CMake, and Python, Esteban reduced maintenance overhead and improved onboarding for new contributors, laying a scalable foundation for future development and more robust data processing workflows.

Jan 1, 2026January 2026 monthly summary for IfcOpenShell (repo: IfcOpenShell/IfcOpenShell). Focused on delivering a more reliable, modular build and stronger CI validation to reduce regressions and accelerate integration. Key features delivered include Kernel and Geometry Build System Modernization: consolidated and modernized CMake configuration to build kernels and geometry modules as libraries, improved inter-module linking, and reliable build outputs. This work included commits c739b9338964cec63bc7c6b3c0cabe99444c119e, a609bc61b9f297e92e6682c6f77aa1dabde14351, 128fdcb62e2d7b9756516aec4e6f110251234974. Additionally, CI and Output Validation Improvements for Example Executables refactored executable naming and added CI checks to verify post-build outputs exist, increasing reliability (commit 8f3715c0f14dd2a5b49020c6e7ed1319074fc608). These changes collectively reduce build fragility, improve developer experience, and set the stage for faster feature delivery.

Nov 1, 2025November 2025 delivered major modernization of the IfcOpenShell build system with a modular CMake architecture, enabling per-component builds and streamlined dependency management. CityJSON support was removed from IfcConvert to reduce maintenance surface area. Build/config hygiene was improved with centralized configurations for serializers and geometry mapping, refined installation commands, and optimized dependency linkage. Svgfill was integrated directly into the repository with adjusted install flow, and Eigen3 linkage was tightened to targets that require it. These changes establish a scalable foundation for future modules and serializers, accelerating release readiness and reducing build friction.

Jun 1, 2025June 2025 monthly work summary for IfcOpenShell/IfcOpenShell focused on cross-platform stability and code quality enhancements. Key feature delivered: standardization of the build system to C++17 with a policy to maintain consistent C++ standards across configurations, reducing friction for multi-compiler CI. Minor code quality improvement included a code style correction in IfcOffsetCurveByDistance.cpp (replacing 'or' with '||') to improve readability and enforce consistency.
