AST‑Based Visual Programming for Vue SFC: Design, Implementation, and Demo

By binding a Vue single‑file component’s AST to a visual UI, this project parses templates with node‑html‑parser, transforms scripts via Babel, and processes styles with standard loaders, allowing developers to edit component properties visually, automatically regenerate synchronized source code, and preview changes, with a prototype demo and planned drag‑and‑drop, styling, state, AI, and CI/CD extensions.

How Source Code Is Transformed into Machine Instructions

A compiler transforms source code into executable machine instructions by first tokenizing the text into keywords, identifiers and literals, then parsing these tokens into an abstract syntax tree, generating and optimizing intermediate code, and finally assembling and linking the output for the target architecture or LLVM IR.
