Blinking cursor. Visible whitespace toggle. + *New:* `CodeEditorWidget.h` + +- [ ] **Step 78: Line numbers and gutter** + Fixed-width gutter on the left with line numbers (gray, right-aligned). + Gutter also serves as anchor for future markers (errors, annotations, breakpoints). + Click gutter = select entire line. Current line highlighted. + Gutter width auto-adjusts for file length (3-digit vs 4-digit line numbers). + *Modifies:* `CodeEditorWidget.h` + +- [ ] **Step 79: Auto-indent and smart editing** + Wire `EditorMode.h` into the editor widget. On Enter: auto-indent based on + language rules (Python: indent after colon, C++: indent after brace). + Tab key inserts spaces per language config. Auto-close brackets/quotes. + *Wires:* `EditorMode.h` + +- [ ] **Step 80: Scroll, selection, clipboard** + Smooth scrolling with mousewheel. Shift+click and Shift+arrow for selection. + Ctrl+C/X/V clipboard integration (SDL clipboard API). Ctrl+A select all. + Drag to select. Double-click selects word, triple-click selects line. + *Modifies:* `CodeEditorWidget.h` + +- [ ] **Step 81: Code folding** + Collapse/expand function bodies and block statements.

Click to scroll. Highlight viewport position. Color-coded + to match syntax highlighting. Toggle via View menu. + *Modifies:* `CodeEditorWidget.h` + +- [ ] **Step 83: Additional tree-sitter grammars** + Add tree-sitter grammars via FetchContent for JavaScript, TypeScript, Java, + Rust, and Go. Add `EditorMode` configs for each (indent rules, comment style, + bracket pairs). Language menu updated. Syntax highlighting works for all 8 + languages.

Keyboard + shortcut cheat sheet. Dismisses when a file is opened. + *Wires:* `WelcomeScreen.h` + +- [ ] **Step 88: Drag-and-drop file open** + Handle SDL_DROPFILE events. Drop a file onto the editor window → open it + in a new tab. Drop a folder → set as workspace root. Visual feedback + during drag (overlay "Drop to open"). + *Modifies:* `main.cpp` + +- [ ] **Step 89: File watching and auto-reload** + Detect external file changes (stat-based polling every 2s). If file changed + on disk and buffer is clean → auto-reload. If buffer is dirty → prompt + "File changed on disk. Reload?"

"Update" shows available newer versions. + Changes write back to the appropriate dependency file. + *New:* `DependencyPanel` in `main.cpp` + +- [ ] **Step 130: Library API indexing via LSP** + When a package is imported, leverage the LSP server to extract its public API + surface. Send `workspace/symbol` queries and `textDocument/completion` with + library prefix to discover available functions, classes, constants. + Cache results in `ExternalModule` AST nodes (name, public symbols, type signatures). + *Modifies:* `LSPClient.h`, `ExternalModule` AST concept + +- [ ] **Step 131: Library API indexing via type stubs** + Fallback for when LSP isn't available or insufficient. Parse type stub files: + - Python: `.pyi` stub files (typeshed, bundled stubs) + - TypeScript: `.d.ts` declaration files + - C/C++: header files (tree-sitter parse for function signatures) + - Rust: parse `lib.rs` public items + Extract function signatures, class/struct definitions, constants into + `TypeSignature` AST nodes attached to `ExternalModule`. + *New:* `StubParser.h`, modifies `ExternalModule` AST concept + +- [ ] **Step 132: Library symbol browser** + New panel or Explorer sub-section: "Libraries".

Code is built UP from library +building blocks rather than hallucinated from training data. Imported libraries +are a convenience, not a 100% constraint — users can always write any code +they want, but the system surfaces library functions first and nudges toward +what's already available. + +- [ ] **Step 134: Available primitives registry** + Create `PrimitivesRegistry.h` that aggregates all available symbols: + - Built-in language primitives (Python builtins, C++ std library, etc.) + - Imported library symbols (from `ExternalModule` AST nodes) + - User-defined symbols (from the current module's AST) + Registry provides: `getAvailableFunctions()`, `getAvailableTypes()`, + `getAvailableConstants()`, filtered by scope and import state. + *New:* `PrimitivesRegistry.h` + +- [ ] **Step 135: Library-aware completion** + Modify the completion system (LSP + Whetstone) to **prioritize** symbols + from `PrimitivesRegistry` without excluding others.

Completions include + parameter types from `TypeSignature`. + *Modifies:* `CodeEditorWidget.h`, `LSPClient.h` + +- [ ] **Step 136: Agent library-aware mode** + New agent capability flag: `preferImports`. When set, the agent + (via WebSocket API) **prefers** inserting code that references symbols in + `PrimitivesRegistry`, and warns (not rejects) when using symbols outside + imported libraries. The `ASTMutationAPI` checks mutations: if a mutation + references a function not in any `ExternalModule` or the current module, + return a warning listing available alternatives — but still allow the + mutation. An optional `strictMode` flag is available for users who DO want + hard enforcement, but it defaults to off. + *Modifies:* `ASTMutationAPI.h`, `WebSocketServer.h` + +- [ ] **Step 137: Function composition builder** + New UI mode: "Compose". Shows a visual flow of available library functions. + User picks a function → sees its inputs/outputs → picks the next function + whose input matches the previous output. Builds a pipeline/chain visually. + Generates code from the composition. Think: visual dataflow programming + backed by real library APIs. + *New:* `CompositionBuilder.h`, `CompositionPanel` in `main.cpp` + +- [ ] **Step 138: Type-aware code generation** + Enhance generators to use `TypeSignature` information from imported libraries. + When generating C++ from Python code that uses numpy, the generator knows + `numpy.array` maps to `std::vector` (or Eigen::MatrixXd). + Cross-language projection respects library type mappings. + *Modifies:* `CrossLanguageProjector.h`, `Generator.h` + +- [ ] **Step 139: Library compatibility matrix** + Track which libraries have equivalents across languages.

Stored as a + configurable JSON mapping file. + *New:* `LibraryCompatibility.h` + +- [ ] **Step 140: Constructive coding tests** + End-to-end tests verifying: + 1. Import numpy → agent prioritizes numpy/builtin functions in suggestions + 2. Remove import → agent's prioritized primitives shrink (but arbitrary code still allowed) + 3. Agent with `preferImports` warns on out-of-library usage but doesn't block + 4. Agent with optional `strictMode` does block out-of-library usage + 5. Cross-language projection with library mapping works + 6. Function composition builder generates correct code + 7. Type-aware generation produces compilable output + *New:* `step140_test.cpp` and supporting test infrastructure + +--- + +## Phase 5c: Emacs Ecosystem Integration (Steps 141–146) + +For Emacs users: respect their init.el, load their packages, expose Emacs +functionality through the Whetstone UI. + +- [ ] **Step 141: Emacs daemon with user config** + Modify the Orchestrator's Emacs daemon to start with the user's init file. + Setting: "Emacs Config Path" (defaults to `~/.emacs.d/init.el`). + Daemon loads user's packages (MELPA, ELPA, straight.el, use-package). + Startup log shown in Output panel. Errors in init.el reported as diagnostics. + *Modifies:* `EmacsIntegration.h`, `Orchestrator.h` + +- [ ] **Step 142: Elisp package browser** + New panel section for Emacs users: "Emacs Packages". Lists loaded packages + from the running daemon (query via `package-alist`). Shows: package name, + version, description. "Load Package" button sends `(require 'package-name)` + to the daemon. Status: loaded/available/not-installed. + *New:* `EmacsPackageBrowser` panel + +- [ ] **Step 143: Elisp function discovery** + Query the running Emacs daemon for available functions from loaded packages. + Send `(apropos-internal "prefix")` → get function list. + Send `(describe-function 'name)` → get docstring and signature. + Populate `ExternalModule` AST nodes for Elisp libraries. + Feed into `PrimitivesRegistry` for constrained coding. + *Modifies:* `ElispCommandBuilder`, `PrimitivesRegistry.h` + +- [ ] **Step 144: Emacs keybinding deep integration** + Go beyond the simple keybinding profile. In Emacs layout mode, support: + - M-x command execution (sends to Emacs daemon) + - Emacs-style prefix keys (C-x C-f, C-x C-s, C-c prefix maps) + - Minibuffer emulation at the bottom of the editor + - Mode line showing major/minor modes + Keybindings loaded from user's Emacs config (key-binding query to daemon). + *Modifies:* `KeybindingManager.h`, `LayoutManager.h` + +- [ ] **Step 145: Org-mode and Literate programming support** + Parse `.org` files using a tree-sitter-org grammar. Render org-mode + documents with headings, source blocks, and prose. Source blocks + are editable with full syntax highlighting and LSP support. + Execute source blocks via the Emacs daemon or language runners. + Results rendered inline (like Jupyter notebooks). + *New:* tree-sitter-org grammar, `OrgMode.h` + +- [ ] **Step 146: Emacs-Whetstone bridge** + Bidirectional sync: Emacs buffers ↔ Whetstone buffers. When the user + has the Emacs layout active, they can switch to pure Emacs (daemon + connected to a graphical frame) for operations Whetstone doesn't + support yet, then switch back. Buffer state synchronized via + the Orchestrator's RPC channel. + *Modifies:* `Orchestrator.h`, `EmacsIntegration.h` + +--- + +## Phase 5d: Full Language Coverage (Steps 147–153) + +Complete generators and CST-to-AST conversion for all supported languages. +Sprint 4 added tree-sitter grammars for syntax highlighting; Sprint 5 +adds full semantic support. + +- [ ] **Step 147: JavaScript/TypeScript CST-to-AST** + Full tree-sitter CST-to-AST conversion for JavaScript and TypeScript. + Handle: functions (arrow, declaration, expression), classes, async/await, + destructuring, template literals, modules (import/export), JSX. + TypeScript: type annotations mapped to Whetstone Type AST nodes. + *Modifies:* `Parser.h` + +- [ ] **Step 148: JavaScript/TypeScript generator** + Generate JavaScript and TypeScript source from Whetstone AST. + Handle: function declarations, arrow functions, classes, async/await, + destructuring, template literals, import/export statements. + TypeScript generator includes type annotations.

Memory annotations map to: @Reclaim(Tracing) + → GC-managed (default), @Owner(Single) → AutoCloseable/try-with-resources. + *Modifies:* `Parser.h`, `Generator.h` + +- [ ] **Step 150: Rust CST-to-AST and generator** + Full tree-sitter Rust parsing: functions, structs, enums, traits, impls, + lifetimes, pattern matching, Result/Option. Generator produces Rust with + proper ownership semantics. Memory annotations map naturally: @Owner(Single) + → owned types, @Owner(Shared_ARC) → Arc, @Lifetime(RAII) → Drop trait, + @Reclaim(Tracing) → Rc with caution note. + *Modifies:* `Parser.h`, `Generator.h` + +- [ ] **Step 151: Go CST-to-AST and generator** + Full tree-sitter Go parsing: functions, structs, interfaces, goroutines, + channels, defer, multiple return values. Generator produces Go with + proper package/import structure. Memory annotations map to: @Reclaim(Escape) + → heap allocation via escape analysis, @Deallocate(Explicit) → manual + Close()/Release() patterns, @Owner(Single) → ownership convention comments. + *Modifies:* `Parser.h`, `Generator.h` + +- [ ] **Step 152: Cross-language projection for new languages** + Extend `CrossLanguageProjector` to handle projection between all pairs of + supported languages (Python, C++, Elisp, JS/TS, Java, Rust, Go). + Annotation adaptation rules for each target.
