PROFILE
Stanislaw Gruszka
During a two-month period, Stefan delivered BPFtrace language support across the macvim-dev/macvim and nvim-treesitter/nvim-treesitter repositories, focusing on editor integration and kernel tracing tooling. He implemented filetype detection, syntax highlighting, and indentation for BPFtrace scripts in Vim using Vim script and Lua, ensuring a consistent editing experience. In nvim-treesitter, he extended parser capabilities for BPFtrace, enabling advanced syntax highlighting and laying groundwork for future tooling. Stefan also contributed to bpftrace/bpftrace by optimizing probe matching with a lazy kernel symbol reader in C++, improving error handling, and enhancing reliability in kprobe attachment, demonstrating depth in system programming and debugging.

Dec 1, 2025December 2025 focused on delivering BPFtrace support in Vim for macvim with end-to-end UX improvements: filetype detection for BPFtrace (including hashbang-driven detection and *.bt recognition), a dedicated syntax highlighting plugin, indentation support, and formatting adjustments that mirror C-like languages. A cohesive sequence of commits introduced the ftplugin and runtime syntax rules, enabling editing, syntax highlighting, proper indentation, and consistent comments formatting for BPFtrace files. This work closes multiple issues and lays the groundwork for broader BPFtrace tooling in the editor.
