ClosedCode v0.1.0

🎉 ClosedCode v0.1.0

A local-only, no-egress AI coding workspace with full-featured CLI, desktop GUI, and TUI support.

🆕 New in v0.1.0 — chat-pane workspace & session management (June 21, 2026)

• Multiple chat sessions as TABS: the bottom chat pane is now a tabbed workspace. + opens a new session as a tab; click a tab to switch, the pencil renames it inline, and × or a middle-click closes it. The open tabs are persisted per workspace and restored on restart.
• Searchable session-history popup (the clock icon, dropping down on-screen and staying within the viewport): a search box filters the list, each row reveals rename (pencil) and delete (trash, with a confirm) actions on hover, and a "もっと読む" (load more) button fetches sessions beyond the synced/trimmed working set.
• Category tabs (tabs-within-tabs) across the panels: a チャット category above the session tabs in the chat pane, エクスプローラー on the left sidebar and レビュー on the right sidebar — a scaffold for future categories such as a terminal.
• Theme-aware pane-resize cursor: the resize handles use a custom double-arrow cursor (dark on light themes, light on dark) instead of the OS cursor that rendered as a hard-to-see white glyph, plus a visible hover divider.
• Fixes: a crash when switching session tabs mid-stream (reading 'id'), a blank agent selector in the composer (the vanilla Select snapshotted its options before the agents loaded), and the splash + main window briefly appearing on screen together at startup.

Also in this release (June 20, 2026)

• Interactive TUI works end-to-end: prompts and slash/shell commands now stream immediately (no more stalling on the home screen), permission and question prompts appear again, and the launch flags --continue (resume the most recent session), --model, and --fork are honored.
• Linux CLI/TUI build is glibc (Debian-built): closedcode-linux-x64.tar.gz is produced on Debian (glibc) via Dockerfile.sea-linux; musl/Alpine is not a build target this release. The npm wrapper declares linux-arm64 for forward-compat but does not yet publish it.
• Stability hardening: the in-house vanilla reactivity shim (ErrorBoundary / Show / For resource cleanup + synchronous-error routing) and serialized SQLite transactions remove a family of boot/teardown races.
• Docs: full JSDoc coverage of the own-source code + regenerated bilingual (en/ja) API reference.

Earlier in the dev line (June 16, 2026)

• New tab = in-memory untitled buffer: the editor "+" no longer creates an untitled.md on disk or errors with ENOENT — it opens an empty in-memory buffer and prompts a native Save As on first save (then swaps the tab for the real file; discard-safe).
• Customizable toolbar: Office-Quick-Access-Toolbar-style two-pane reorder / show-hide customizer at 設定 → 一般 → ツールバー; order + visibility persist.
• Editor find/replace: VS Code-style widget (case/word/regex, match counter, replace + replace-all).
• Bootstrap modals: delete confirmation and save-on-close (保存しますか？) replace native popups.
• Stability fixes: review-panel diff previews, blank editor/tab panes, white splash / first-paint, unsaved-edit preservation.
• Docs: refreshed online manual + JSDoc API reference (en/ja).

✨ Highlights

🖥️ Desktop GUI (Electron)

• Vanilla (solid-free) interface — the in-house reactivity shim fully replaces solid-js
• In-app CodeMirror editor with tabs, file tree, and custom file operations
• Tabbed chat-pane workspace with a searchable session history and tabs-within-tabs category bars
• Local LLM providers (Ollama, LM Studio, OpenAI-compatible endpoints)
• Build-less architecture (native ESM renderer served over vcc://)

💻 CLI + 🖲️ TUI

• One Node SEA binary: run with no args for the interactive TUI, or subcommands for the CLI
• Syntax-highlighted diffs, external editor integration, MCP/skill dialogs
• Works with any OpenAI-compatible LLM

🔐 Security & Privacy

• ✅ No telemetry · ✅ No cloud services required · ✅ Local execution only · ✅ Bring-your-own LLM
