Adds test/terminal/buffer/range_test.dart — 38 unit tests covering the small pure-Dart files in lib/src/terminal/src/core/buffer/: - cell_offset.dart 23 / 23 (was 0 / 23) - range.dart 13 / 13 (was 0 / 13) - segment.dart 13 / 13 (was 0 / 13) - range_line.dart 30 / 30 (was 0 / 30) - range_block.dart 48 / 48 (was 0 / 48) Total project line coverage 34.90% → 36.39%; coverage_floor in pubspec.yaml bumped 34 → 36 in lockstep. Tests exercise the abstract BufferRange operator==/hashCode/toString via a local _StubRange (BufferRangeLine and BufferRangeBlock both override those, so the base versions are otherwise unreachable — worth a stub rather than carving the lines out of coverage). The denormalized-input branches in Block contain/toSegments/extend get explicit cases too. Pure Dart, no Flutter dependency — uses package:test/test.dart and runs in <100ms. First batch under T-91; line.dart and buffer.dart land in subsequent commits with their own floor bumps. Co-Authored-By: Claude <noreply@anthropic.com>
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/.
