Adds test/terminal/escape/parser_test.dart — 70 unit tests covering the parser's dispatch surface end-to-end: - single-byte controls (BEL, BS, HT, LF/VT/FF, CR, SO, SI), - ESC sequences (D, E, H, M, =, >, 7, 8, ( name, ) name, unknown), - CSI cursor moves (A/B/C/D/E/F/G/H/d/f) with default + 0-as-1 fallback semantics, - erase / scroll / line-insert/delete / chars (J, K, L, M, P, S, T, X, @, b, g, r), - device attributes (c / >c / =c) and DSR (5, 6), - window manipulation (CSI 8 t resize, CSI 18 t sendSize, ignored no-op codes, malformed CSI 8 t), - mode set/reset (h/l, ? prefix for DEC modes — covering ?1, ?3, ?5, ?6, ?7, ?9, ?12, ?25, ?47, ?66, ?1000, ?1002, ?1003, ?1004, ?1005, ?1006, ?1007, ?1015, ?1047, ?1048, ?1049, ?2004, + unknown fallback), - SGR styling (resets, set/unset for every attr, 16-colour foreground + background, 256-colour, 24-bit RGB, 39 / 49 resets, unknown → unsupportedStyle), - OSC 0/1/2 (BEL- and ST-terminated), unknown OSC, incomplete sequence held back across writes, - unknown CSI final byte → unknownCSI, - token bookkeeping (tokenBegin / tokenEnd advance with consumed bytes). Plus EscapeEmitter — every reply string format (primary / secondary / tertiary device attributes, operating status, cursor position, bracketed paste, size). Coverage delta: - parser.dart: 0 / 462 → 504 / 514 (98.1%; the remaining 10 lines sit inside the `// ignore: dead_code` SGR loop, which I'm surfacing for separate review rather than extending tests around). - emitter.dart: 1 / 11 → 11 / 11. - Total project: 43.20% → 49.38%; coverage_floor bumped 43 → 49. Two real source-code issues found while writing tests, fixed in the same commit: 1. Swapped docstrings on `_escHandleSetAppKeypadMode` / `_escHandleResetAppKeypadMode`. The function names + dispatch table + bodies all match the VT spec correctly (ESC = enables, ESC > disables); only the doc-comments were swapped. Now read the right way around. 2. `case 10061000:` in `_setDecMode` was unreachable (no DEC mode has that value). Almost certainly a typo where `case 1006:` meant to glue onto `case 1000:` but a newline went missing. Mode 1006 is already handled separately at its own clause as `MouseReportMode.sgr`. Removed.

clide
An IDE for Claude Code CLI. Native rendering, terminal-first interaction, pql-powered queries, canvas and graph surfaces. Linux and macOS.
Architecture
Single Flutter package at the repo root. The app hosts everything in-process: IPC server, subsystem handlers (pane, files, editor, git, pql), and the extension framework. tmux owns Claude session persistence.
lib/— all Dart code. Kernel services (theme, i18n, settings, panels, commands, focus), UI widgets, built-in extensions, and the extension contract.ptyc/— small C helper. Spawns a PTY + child and hands the master fd back overSCM_RIGHTS. Every pane (shell, tmux, claude, LSP, debug adapter) goes through it.- pql — external supporter tool. Clide wraps it for every query surface; never re-implements it.
Claude drives the UI through a clide CLI surface (Bash, not MCP). Every CLI subcommand has a UI affordance and every UI action has a CLI equivalent.
Built-in extensions
canvas, claude, claude_control, decisions, diff, editor, extensions_ui, files, git, graph, grammars_core, ipc_status, keybindings_ui, markdown, pql, problems, settings_ui, terminal, theme_picker, tickets, todos, welcome.
Building
Requires Flutter (stable channel) on the host. One-time setup:
make hooks && flutter pub get
Then:
make run # launch the desktop app
make test # fast suite: analyze + format + unit + widget + golden
make test-core # core subsystem tests (IPC, PTY, git, pane registry)
make test-integration # real app boot integration tests
make build-linux # flutter build linux
make build-macos # flutter build macos
make ptyc-build # build the ptyc PTY-spawn helper
make push-check # pre-push gate: decisions + core + fast tests
Status
Pre-v2.0 (2.0.0-dev). Interaction model and panel system landed. The Python Textual v1.2.0 predecessor is archived under legacy/.
Design doc: docs/initial-plan.md. Architectural decisions: decisions/.
