2 Commits • 1 Features
Mar 1, 2026March 2026: jarun/nnn delivered stability improvements in selection handling and reinforced code quality with static analysis tooling. Key work focused on the Selection Inversion Stability fix and a Code Quality Enforcement upgrade to clang-tidy. The selection inversion fix reconciles off-screen entries with the selection buffer (selbuf) using findmarkentry, eliminating unstable behavior during inversion and improving user experience. The clang-tidy update strengthens code quality checks and reduces the risk of build-time issues due to style or static analysis problems. Impact includes smoother selection operations for end-users, more reliable behavior across the selection workflow, and a maintainable codebase with stronger quality gates. Technologies demonstrated include C/C++ development practices, static analysis with clang-tidy, robust selection buffer management, and integration of quality checks into the development workflow.

Dec 1, 2025December 2025 (jarun/nnn) focused on performance optimization of the Output Buffering System. Implemented pipe-based buffering to replace temporary files, simplified the command execution and buffering loop, standardized an 8 KB buffer size, and streamlined the selection buffer logic for better efficiency. These changes reduce IO overhead in the floating window path, improve throughput, and enhance code readability and maintainability. The work also prepared the codebase for easier future enhancements and better lint hygiene.
