…arch, and resizing
- Frontend:
- Added `xterm-addon-fit` for responsive terminal resizing.
- Implemented shell state management (input buffer, cursor, history).
- Added key bindings: Ctrl+C (reset), Ctrl+L (clear), Ctrl+A/E (home/end), Ctrl+U/W (delete line/word).
- Implemented Tab completion with a custom dropdown UI overlay.
- Implemented Ctrl+R for basic reverse history search.
- Updated `HeadlessWasmAdapter` to support `reset()` and structured completion results.
- Backend (`eldritch-wasm`):
- Added `HeadlessRepl::reset()` to clear the internal buffer.
- Updated `HeadlessRepl::complete()` to return `{ suggestions: [...], start: usize }` instead of a flat list, enabling correct inline replacement.
- Added tests for reset and completion structure.
- Rebuilt WASM artifacts with `fake_bindings` feature.

👋 Jules, reporting for duty! I'm here to lend a hand with this pull request. When you start a review, I'll add a 👀 emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down. I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job! For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with New to Jules? Learn more at jules.google/docs. For security, I will only act on instructions from the user who triggered this task. |
- **Cursor Flicker:** Optimized `redrawLine` to avoid clearing the entire line (including prompt) and rewrite only the input buffer using `\r` + content + `\x1b[K`. Added fast-path logic in `onData` for appending characters or backspacing at the end of the line, bypassing `redrawLine` entirely for the most common typing scenarios. - **Tab Indenting:** Updated Tab handler to insert 4 spaces if the input buffer is empty or consists only of whitespace, enabling standard indentation behavior. - **Function Termination:** Ensured `state.prompt` is reset to `>>> ` when a command returns `"complete"` status, fixing an issue where the prompt would remain `.. ` after finishing a multi-line function definition.
