PROFILE

Marcus Mellor

Worked across the getsolus/packages and siliconcompiler/siliconcompiler repositories to deliver packaging upgrades, toolchain modernization, and improved visualization workflows. Upgraded core components such as r2modman, Cemu, Zig, and EDA toolchains, focusing on ABI compatibility, dependency management, and cross-platform stability. Enhanced desktop integration by implementing AppStream metadata and standardizing desktop file naming, while introducing Wayland and GTK4 support for modern environments. In siliconcompiler, developed a dynamic VCD visualization workflow with runtime binary checks and graceful fallback, improving reliability. Leveraged C, C++, and Python alongside CMake and packaging automation to ensure maintainable deployments, robust CI, and streamlined downstream integration.

Month: 2025-09 — Key work delivered in getsolus/packages focused on modernizing toolchains, enabling Wayland support, and keeping components up to date. The summary below covers key features, major fixes, impact, and skills demonstrated. Key features delivered: - Zig Compiler Update to 0.14.1: ABI changes across libraries and symbols; updated package definition and source tarball to align with the new compiler. - Ghostty Terminal Emulator Update to 1.2.0: Updated to 1.2.0; updated ABI libraries and symbols due to GTK4 layer shell integration; adjusted package configuration. - GTK4 Layer-Shell Library Introduced (Wayland) 1.2.0: Added gtk4-layer-shell 1.2.0 to packages; includes ABI files, monitoring configuration, and packaging for Wayland desktops. - ncdu Update to 2.9.1: Updated to 2.9.1; revised package definition and source URL; updated ABI symbol list for the new version. Major bugs fixed: - Resolved ABI compatibility issues introduced by toolchain updates; ensured packaging definitions and source tarballs reflect new versions; addressed GTK4/Wayland integration-related packaging adjustments to prevent build failures. Overall impact and accomplishments: - Maintained build stability on modern toolchains, expanded Wayland support, and kept critical utilities current (Zig, Ghostty, ncdu) reducing maintenance risk and enabling smoother downstream deployments. Technologies/skills demonstrated: - Toolchain/ABI management, packaging automation, GTK4/Wayland integration, dependency/version governance, repository maintenance, cross-component coordination.

June 2025 monthly summary for siliconcompiler/siliconcompiler: Delivered a robust VCD visualization workflow with a dynamic surfer binary check and fallback to gtkwave, improving UX when surfer is unavailable. Improved code quality in the surfer module and stabilized tests by skipping VCD showtools tests until the surfer release adds exit functionality, reducing flaky CI runs. These changes enhance reliability, reduce support overhead, and demonstrate strong Python tooling, testing discipline, and release-gate practices.
