This repository hosts a Chinese translation of the Software Foundations textbook series, providing an interactive web-based platform for learning formal methods and programming language theory using the Coq proof assistant. The architecture consists of volume-specific directories (LF, PLF, QC, SECF, SLF, VC, VFA) containing Coq source files, generated HTML, and shared interactive components. Key features include in-browser Coq proof checking via jsCoq, proof visibility toggling, bilingual term highlighting, and slide presentation mode. The system relies on external dependencies like jsCoq, jQuery, and jQuery UI for its interactive functionality.
