How koutarou4096/g-tracer works

This browser-based pseudo-language tracer helps exam learners inspect program execution and convert programs to code. The main workflow is to enter a program and initial values, parse the program into an AST, execute it with tracing, and view the resulting state table. A separate code-generation branch produces Python; the README also documents Java generation as implemented in JavaScript, though its page button is not yet present. The excerpts show the main calls; the page markup and unsampled generator details were not inspected.
