 Project Goals
 -------------
@@ -26,89 +30,6 @@ Project Goals
  so a GUI can grow independently of the TUI.
 - Minimize dependencies; the GUI layer remains optional and isolated.

-User Experience (intended)
--------------------------
-
- Terminal first: instant startup, responsive editing, no surprises
-  over SSH.
- Optional GUI: an ImGui‑based window with tabs, menus, and
-  palette—sharing the same editor core and command model.
- Discoverable command model: WordStar/VDE style with a `C-k` prefix,
-  Emacs‑like incremental search, and context help.
- Sensible defaults with a simple config file for remaps and theme
-  selection.
- Respect the file system: no magic project files; autosave and
-  crash‑recovery journals are opt‑in and visible.
-
-Core Features (roadmapped)
--------------------------
-
- Buffers and windows
-    - Multiple file buffers; fast switching, closing, and reopening.
-    - Split views (horizontal/vertical) in TUI and tiled panels in
-      GUI.
- Editing primitives
-    - Gap buffer (primary) with an alternative piece table for
-      large‑edit scenarios.
-    - Kill/yank ring, word/sentence/paragraph motions, and rectangle
-      ops.
-    - Undo/redo with grouped edits and time‑travel scrubbing.
- Search and replace
-    - Incremental search (C-s) and regex search (C-r) with live
-      highlighting.
-    - Multi‑file grep with a quickfix list; replace with confirm.
- Files and projects
-    - Robust encoding/line‑ending detection; safe writes (atomic where
-      possible).
-    - File tree sidebar (GUI) and quick‑open palette.
-    - Lightweight session restore.
- Language niceties (opt‑in, no runtime servers required)
-    - Syntax highlighting via fast, table‑driven lexers.
-    - Basic indentation rules per language; trailing whitespace/EOF
-      newline helpers.
- Extensibility (later)
-    - Command palette actions backed by the core command model.
-    - Small C++ plugin ABI and a scripting shim for config‑time
-      customization.
-
-Interfaces
----------
-
- CLI: the primary interface. `kte [files]` starts in the terminal,
-  adopting your `$TERM` capabilities. Terminal mode is implemented
-  using ncurses.
- GUI: an optional ImGui‑based frontend that embeds the same editor
-  core.
-
-Architecture (intended)
-----------------------
-
- Core model
-    - Buffer: file I/O, cursor/mark, viewport state, and edit
-      operations.
-    - GapBuffer: fast in‑memory text structure for typical edits.
-    - PieceTable: alternative representation for heavy insert/delete
-      workflows.
- Controller layer
-    - InputHandler interface with `TerminalInputHandler` and
-      `GUIInputHandler` implementations.
-    - Command: normalized operations (save, kill, yank, move, search,
-      etc.).
- View layer
-    - Renderer interface with `TerminalRenderer` and `GUIRenderer`
-      implementations.
- Editor: top‑level state managing buffers, messaging, and global
-  flags.
-
-Performance and Reliability Targets
-----------------------------------
-
- Sub‑millisecond keystroke to screen update on typical files in TUI.
- Sustain fluid editing on multi‑megabyte files; graceful degradation
-  on very large files.
- Atomic/safe writes; autosave and crash‑recovery journals are
-  explicit and transparent.
-

 Status
 ------

- The project is under active evolution toward the above architecture
-  and UX. The terminal interface now uses ncurses for input and
-  rendering. GUI work will follow as a thin, optional layer. ke
-  compatibility remains a primary constraint while internals modernize.
-
-Roadmap (high level)
--------------------
-
-1. Solidify core buffer model (gap buffer), file I/O, and
-   ke‑compatible commands.
-2. Introduce structured undo/redo and search/replace with
-   highlighting.
-3. Stabilize terminal renderer and input handling across common
-   terminals. (initial ncurses implementation landed)
-4. Add piece table as an alternative backend with runtime selection
-   per buffer.
-5. Optional GUI frontend using ImGui; shared command palette.
-6. Language niceties (syntax highlighting, indentation rules) behind a
-   zero‑deps, fast path.
-7. Session restore, autosave/journaling, and safe write guarantees.
-8. Extensibility hooks with a small, stable API.

- Core ke key chords: C-g (cancel), C-k s/x/q/C-q, C-l, basic arrows, Enter/Backspace, C-s (simple find).
-
-Guiding principles
-
- Keep the core small and understandable; evolve incrementally.
- Separate model (Buffer/Editor), control (Input/Command), and view (Renderer).
- Favor terminal first; GUI hooks arrive later behind interfaces.
-
-✓ Milestone 0 — Wire up a minimal app shell
-
-1. main.cpp
-    - Replace demo printing with real startup using `Editor`.
-    - Parse CLI args; open each path into a buffer (create empty if none). ✓ when `kte file1 file2` loads buffers and
-      exits cleanly.
-2. Editor integration
-    - Ensure `Editor` can open/switch/close buffers and hold status messages.
-    - Add a temporary “headless loop” to prove open/save calls work.
-
-✓ Milestone 1 — Command model
-
-1. Command vocabulary
-    - Flesh out `Command.h/.cpp`: enums/struct for operations and data (e.g., InsertChar, MoveCursor, Save, Quit,
-      FindNext, etc.).
-    - Provide a dispatcher entry point callable from the input layer to mutate `Editor`/`Buffer`.
-    - Definition of done: commands exist for minimal edit/navigation/save/quit; no rendering yet.
-
-✓ Milestone 2 — Terminal input
-
-1. Input interfaces
-    - Add `InputHandler.h` interface plus `TerminalInputHandler` implementation.
-    - Terminal input via ncurses (`getch`, `keypad`, non‑blocking with `nodelay`), basic key decoding (arrows, Ctrl, ESC
-      sequences).
-2. Keymap
-    - Map ke chords to `Command` (C-k prefix handling, C-g cancel, C-l refresh, C-k s/x/q/C-q, C-s find start, text
-      input → InsertChar).
-3. Event loop
-    - Introduce the core loop in main: read key → translate to `Command` → dispatch → trigger render.
-
-✓ Milestone 3 — Terminal renderer
-
-1. View interfaces
-    - Add `Renderer.h` with `TerminalRenderer` implementation (ncurses‑based).
-2. Minimal draw
-    - Render viewport lines from current buffer; draw status bar (filename, dirty, row:col, message).
-    - Handle scrolling when cursor moves past edges; support window resize (SIGWINCH).
-3. Cursor
-    - Place terminal cursor at logical buffer location (account for tabs later; start with plain text).
-
-Milestone 4 — Buffer fundamentals to support editing
-
-1. GapBuffer
-    - Ensure `GapBuffer` supports insert char, backspace, delete, newline, and efficient cursor moves.
-2. Buffer API
-    - File I/O (open/save), dirty tracking, encoding/line ending kept simple (UTF‑8, LF) for v0.1.
-    - Cursor state, mark (optional later), and viewport bookkeeping.
-3. Basic motions
-    - Left/Right/Up/Down, Home/End, PageUp/PageDown; word f/b (optional in v0.1).
-
-Milestone 5 — Core editing loop complete
-
-1. Tighten loop timing
-    - Ensure keystroke→update→render latency is reliably low; avoid unnecessary redraws.
-2. Status/messages
-    - `Editor::SetStatus()` shows transient messages; C-l forces full refresh.
-3. Prompts
-    - Minimal prompt line for save‑as/confirm quit; blocking read in prompt mode is acceptable for v0.1.
-
-Milestone 6 — Search (minimal)
-
-1. Incremental search (C-s)
-    - Simple forward substring search with live highlight of current match; arrow keys navigate matches while in search
-      mode (ke‑style quirk acceptable).
-    - ESC/C-g exits search; Enter confirms and leaves cursor on match.
-
-Milestone 7 — Safety and polish for v0.1
-
-1. Safe writes
-    - Write to temp file then rename; preserve permissions where possible.
-2. Dirty/quit logic
-    - Confirm on quit when any buffer is dirty; `C-k C-q` bypasses confirmation.
-3. Resize/terminal quirks
-    - Handle small terminals gracefully; no crashes on narrow widths.
-4. Basic tests
-    - Unit tests for `GapBuffer`, Buffer open/save round‑trip, and command mapping.
-
-Out of scope for v0.1 (tracked, not blocking)
-
- Undo/redo, regex search, kill ring, word motions, tabs/render width, syntax highlighting, piece table selection, GUI.
-
-Implementation notes (files to add)
-
- Input: `InputHandler.h`, `TerminalInputHandler.cc/h` (ncurses).
- Rendering: `Renderer.h`, `TerminalRenderer.cc/h` (ncurses).
- Prompt helpers: minimal utility for line input in raw mode.
- Platform: small termios wrapper; SIGWINCH handler.
-
-Acceptance checklist for v0.1
-
- Start: `./kte [files]` opens files or an empty buffer.
- Edit: insert text, backspace, newlines; move cursor; content scrolls.
- Save: `C-k s` writes file atomically; dirty flag clears; status shows bytes written.
- Quit: `C-k q` confirms if dirty; `C-k C-q` exits without confirm; `C-k x` save+exit.
- Refresh: `C-l` redraws.
- Search: `C-s` finds next while typing; ESC cancels.
-
-Next concrete step
-
- Stabilize cursor placement and scrolling logic; add resize handling and begin minimal prompt for save‑as.
