After session-id binding (T-146), a pane that attached (via new-session -A) to a session created before the change — which has no --session-id, so its transcript is under a different id — would wait forever for a transcript that never appears. Same on any unconnectable session. Before spawning, if no transcript exists for our deterministic session id, kill the clide tmux session of that exact name so new-session creates a clean one with our --session-id. This self-heals the stuck state on next launch and makes clean-install/first-run robust. Safe by construction: only clide's own session is killed — by its exact clide-claude-<slug> name on the private -L clide socket (a terminal claude never runs there) — and no transcript file is ever deleted. A healthy session's transcript already exists, so re-attach continuity (D-41) is preserved. Co-Authored-By: Claude Opus 4.7 (1M context) <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 (D-41).
lib/— all Dart code. Core subsystems (lib/src/), kernel services (lib/kernel/), UI widgets (lib/widgets/), built-in extensions (lib/builtin/), the extension framework (lib/extension/).- PTY —
lib/src/pty/spawns child processes via Dart FFIposix_openpt()+posix_spawn()directly; no external helper binary. native/— vendored native libraries (libtree-sitter.sowith wasmtime embedded). Linux only today.- 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 (D-6).
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-a11y # accessibility contract tests
make test-integration # real app boot integration tests
make build-linux # flutter build linux
make build-macos # flutter build macos
make push-check # pre-push gate: decisions + core + fast + a11y + coverage + changelog
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/.
