Toby developed the Dollar Sign Aware Word Selection feature for the ghostty-org/ghostty terminal emulator, enhancing word selection logic to treat the dollar sign as a word boundary. Working in Zig, he implemented changes that align ghostty’s behavior with iTerm, improving consistency for users who rely on precise text selection in terminal environments. Toby focused on robust boundary handling, adding targeted tests to verify correct selection behavior when encountering dollar signs. His work included preparing changelogs and commits for review, demonstrating attention to maintainability and code quality. The project showcased skills in Zig programming, terminal development, and comprehensive testing practices.
