Virtual Domain Specific Languages via Embedded Projectional Editing
summary
Presents a working hybrid editor that matches AST patterns in Python or JavaScript and renders matched code as live web components, serializing always back to pure GPL text so existing toolchains (linters, LSP) keep working. Implements pattern+projection elements, a small program‑by‑example generator that creates patterns and text widgets from paired samples, and a CodeMirror 6 web demo at https://puredit.korz.dev/. Matches are dynamic with fallback to source when projection fails; implementation is incremental and used on multiple domain examples.
