v0.9.0

Termlet v0.9.0 💻

Termlet v0.9.0 brings a major UX and productivity upgrade across the entire workspace, introducing a Multi-Tab Remote Terminal runner, real Line-Based Shell Stream with multi-line command continuation (\ & Shift+Enter), VS Code Style Draggable Resizing for both the terminal drawer and sidepanel, unified sidebar width, and tab management polish.

---

✨ What's New & Highlights

💻 Multi-Tab Line-Based Terminal Runner

• True Line-Based Stream:
  • Replaced the detached bottom input box with a real terminal emulator stream where the prompt (username@host:path$ [cursor]) follows output directly inline.
  • History entries render as authentic prompt lines with working directory context.
  • Pressing Enter on an empty line naturally emits a fresh prompt on the next line; pressing Ctrl+C prints ^C inline and resets the prompt.
• Multi-Line Command Continuation (\ and Shift+Enter):
  • Write multi-line commands using standard trailing backslash \ (e.g. docker run -d \) or Shift+Enter.
  • Continuation lines render with secondary shell prompt (> ) matching real Bash/Zsh behavior.
  • Pressing Backspace on an empty continuation prompt pops the previous line back into the active input for easy editing.
  • Smart multi-line paste support: pasting multi-line scripts or command blocks automatically parses them into continuation lines and active input ready to inspect and run.
• Multiple Concurrent Terminal Tabs:
  • Open multiple concurrent terminals (Terminal 1, Terminal 2, etc.) multiplexed over the same SSH connection.
  • Each tab maintains independent remote working directory (CWD), history, and command execution state.
  • Run long-running tasks in one tab while executing commands concurrently in another.
• Tab Management Polish:
  • Double-Click to Rename: Double-click any tab title to rename it to something custom like docker, web-server, or logs.
  • Duplicate Tab: Dedicated button next to + to duplicate active tab in its current remote working directory.
  • Horizontal Wheel & Arrow Scrolling: Scroll horizontally with your mouse wheel, click left/right navigation arrows, and enjoy smooth automatic centering on the active tab.
  • Local exit / logout Handling: Typing exit or logout cleanly closes the active tab (or drawer if last tab).

📐 Workspace Layout & Resizing

• VS Code Style Drag-to-Resize Drawer:
  • Drag the top border of the terminal drawer to adjust height smoothly between 100px and workspaceHeight - 50px.
  • Double-click the resize handle to toggle maximize / restore height.
  • Height is saved across app restarts.
• Draggable Sidepanel & Unified Width:
  • Added a draggable vertical resize handle on the right border of the sidepanel.
  • Clamped smoothly between 180px and 60% of the window width, with double-click reset to default (270px).
  • Unified width across Explorer, Ports, and Profiles views, eliminating previous width jumping.
• Workspace-Scoped Drawer:
  • Terminal drawer sits strictly inside the editor workspace to the right of the sidebar, never covering the ActivityBar or file tree.
• ActivityBar Tab Reordering:
  • Moved Remote Profiles & Sessions (Server icon) to the very top above Explorer (Files icon), defaulting to connections on app startup for instant server selection.

⚡ Port Forwarding Stability

• Deterministic Port List Ordering:
  • Fixed a race condition where Go map iteration randomization caused active/inactive port forwarding cards to continually bounce and swap positions on periodic refresh.
  • Ports are now stably sorted by local port and ID on both backend and frontend.

v0.8.0

Termlet v0.8.0 💻

Termlet v0.8.0 introduces a high-performance, interactive Remote SSH Command Runner & Terminal Drawer with stateful working directory persistence, live SFTP directory tree synchronization, interactive TTY interception, and instant cancellation.

---

✨ What's New & Highlights

💻 Interactive Remote SSH Terminal Runner & Drawer

• Persistent Bottom Terminal Drawer:
  • Open a sleek, embedded remote terminal runner directly beneath your SSH file workspace using the shortcut `Ctrl+`` or the bottom Status Bar Terminal toggle button.
  • Seamlessly runs remote shell commands against the active SSH connection without needing an external terminal emulator or third-party tools.
• Stateful Remote Working Directory Tracking (cd Persistence):
  • Preserves working directory across command executions. If you execute cd /var/log && pwd, subsequent commands execute within /var/log.
  • Captures the exact physical directory using POSIX-compliant pwd -P and cleanly propagates working directory changes.
• Bi-directional SFTP Explorer & Workspace Synchronization:
  • Whenever the remote directory changes inside the terminal runner (e.g. cd /etc/nginx), Termlet's remote SFTP tree and navigation breadcrumb automatically sync and reload to that directory in real time.
• Interactive TTY Interception & Smart Editor Hints:
  • Inline subshells cannot run full-screen interactive curses/TTY applications without freezing or sending unprintable terminal escape sequences.
  • Commands requiring an interactive TTY (e.g. vim, vi, nvim, nano, emacs, top, htop, btop, less, more, man) are intelligently intercepted before execution.
  • Termlet provides an actionable hint suggesting the graphical inline code editor, Quick Open (Ctrl+P), or non-interactive alternatives like cat or ps aux.
• Instant In-Flight Command Interruption (Ctrl+C / UI Cancel):
  • Stop running commands immediately by pressing Ctrl+C or clicking the Cancel button.
  • Closes the active SSH execution channel instantly without dropping the main SSH connection or disrupting file transfers.
  • Respects standard clipboard text selection when pressing Ctrl+C.
• Exit Code Reporting & Error Styling:
  • Displays exit codes for commands that return non-zero exit statuses.
  • Failed command output is styled with a distinct rose accent and border (border-rose-500/30), while quiet commands that exit non-zero (such as false or diff) display explicit [Process exited with code X] tags.
• Output Safety & Memory Limits:
  • Strips ANSI color codes for clean typography.
  • Protects webview DOM performance by truncating outputs exceeding 100,000 characters with an alert marker.
• Terminal History & Productivity Shortcuts:
  • Browse command history with Up and Down arrow keys.
  • Quick screen clear via clear command, Ctrl+L, or the trash button.
  • One-click Copy All Output to clipboard.
  • Maximize / restore height toggle buttons.

---

✨ What's New & Highlights

🛡️ SSH Host Key Verification & MitM Attack Protection

• Dual-Layer Known Hosts Store:
  • Automatically queries both the standard OpenSSH ~/.ssh/known_hosts file and Termlet's dedicated application store (~/.config/termlet/known_hosts / %APPDATA%\termlet\known_hosts).
  • Automatically records newly trusted hosts with SHA256 cryptographic fingerprints, host keys, and port numbers without mutating standard system files unless configured.
• Trust On First Use (TOFU) Verification:
  • When connecting to an unknown host for the first time, an interactive modal presents the host address, key type (e.g., ssh-ed25519, ecdsa-sha2-nistp256, rsa-sha2-512), and full SHA256 fingerprint.
  • Allows you to inspect and confirm the remote server's identity before any authentication tokens or credentials are transmitted over the network.
• Strict Host Key Mismatch Detection:
  • If a server's host key changes unexpectedly, Termlet flags a high-priority security warning to prevent Man-in-the-Middle (MitM) eavesdropping and spoofing attacks.
  • Displays side-by-side comparison of the expected fingerprint versus the incoming fingerprint, requiring explicit confirmation before proceeding.

🗂️ Dedicated SSH Security & Known Hosts Manager (termlet://known-hosts)

• Full Workspace Tab Experience:
  • Moved out of general settings into a dedicated, first-class workspace tab (termlet://known-hosts) featuring a shield icon, tab state persistence, and responsive full-width layout.
  • Quick-access button added directly to the bottom status bar (Known Hosts) and from the Security section in Settings.
• Search & Source Filtering:
  • Real-time search across hostnames, key algorithms, and fingerprints.
  • Filter chips to quickly narrow entries between All, Termlet Store, and System Store (~/.ssh/known_hosts).

  • The close button is now neatly embedded in the top-right inside corner of the toast card with comfortable padding (pr-8) preventing any overlap with long notification text.
• Theme-Synchronized Styling:
  • Integrated hover states (bg-zinc-200/50 in light mode, bg-white/10 in dark mode) and subtle border styling.
  • Semantic status colors (emerald success, rose error, amber warning, sky info) dynamically adapt to Termlet's UI theme mode.
• Streamlined Release Notes View Header:
  • Removed duplicate close (x) button in the header above the notes since the editor tab bar already provides standard tab dismiss controls.

🛡️ Robust Fault-Tolerant Foundation (from v0.5.2)

• Sectional <ErrorBoundary>:
  • Isolates errors in side panels, explorer, editor, settings, and release notes without taking down the application.
  • Actionable crash recovery options: Reload View, Technical Stack Details, and Full Restart.
• Centralized Error Parsing:
  • Decodes Go, SSH, SFTP, and OS network errors into actionable guidance across 13 distinct categories.
• Streamlined In-Settings Automatic Updater:
  • Clean update management directly inside Settings without intrusive modals. Real-time download progress and 1-click restart to apply.

v0.5.2

Termlet v0.5.2 🚀

Termlet v0.5.2 brings comprehensive, production-grade error handling across the entire stack, eliminating white-screen crashes, introducing actionable diagnostic hints, and bolstering backend fault tolerance alongside our automatic updater and UI refinements.

---

✨ What's New & Highlights

🛡️ Robust Error Handling & Crash Protection

• React Sectional <ErrorBoundary>:
  • Integrated error boundaries around all major workspace zones (Side panels, Explorer, Editor, Settings, and Release Notes).
  • Component crashes or syntax errors in editors no longer cause white-screen failures.
  • Includes user-facing recovery controls: Reload View, collapsible Technical Details stack viewer, and Full Restart.
• Centralized Error Parsing & Actionable Hints (formatErrorMessage):
  • Automatically translates cryptic Go, SSH, SFTP, and OS errors into structured { title, message, hint, raw } objects across 13 categories:
    • Authentication Failures: Clear advice on username, password, or key passphrases.
    • Connection Refused: Guides users to check sshd status, listening ports, and firewall rules.
    • DNS / Host Resolution: Pinpoints DNS lookups and typos.
    • Connection Timeouts & Network Unreachability: Actionable hints on server reachability and VPN routing.
    • Host Key Verification & Security Warnings: Explicit guidance on untrusted or changed host keys.
    • SFTP Permissions & Missing Files: Clear Linux file permission (chmod/chown) hints.
    • Concurrent File Modification: Interactive conflict warnings with "Overwrite anyway" options.
    • Buffer Limits: Guards on files exceeding editor size limits.
    • Disconnected Sessions: Contextual prompts to reconnect.
• Inline Connection Error Banners:
  • Replaced fleeting toasts in ConnectDialog with persistent inline error alerts above action buttons, complete with troubleshooting hints and a toggleable raw technical details view.
• Remote Explorer Failure Recovery:
  • Replaced misleading "Directory is empty" states during SFTP failures with an explicit error screen and an inline Retry action.
• Go Backend Panic Prevention & Nil Safety:
  • Added centralized getSFTPClient in app.go with strict nil checks and session validation.
  • Added receiver and client nil guards across sftpclient.Client methods before mutex acquisitions.

Full Changelog: v0.5.1...v0.5.2

v0.5.1

Termlet v0.5.1 🚀

Termlet v0.5.1 is a major update bringing seamless in-app automatic update installation (matching Dockit's update architecture), native Windows icon integration, webview favicon fidelity, comprehensive light-mode theme contrast enhancements, and UI control cleanup across platforms.

---

✨ What's New & Highlights

🔄 Automatic In-App Update Installation & Management (Dockit Parity)

• One-Click In-App Updating:
  • Added background update detection shortly after startup that alerts users with a non-intrusive floating toast when a newer version is released.
  • Interactive <UpdateModal>: displays installed version vs new version badges, target package detection tag, release notes, and real-time download progress (percentage and downloaded MB).
  • Native Package & In-Place Installation:
    • Linux (.deb): automatically downloads .deb package and invokes pkexec dpkg -i (with fallback to apt-get install -f -y or desktop package manager), prompting for desktop authorization seamlessly.
    • Linux (.rpm): automatically downloads .rpm package and installs via pkexec rpm -Uvh --replacepkgs.
    • Windows: launches downloaded NSIS setup installer .exe or updates portable .zip in-place.
    • Standalone / Portable: extracts binary in-memory and applies the replacement in-place using selfupdate (or pkexec if destination directory requires root permission).
  • Seamless App Restart: integrated RestartApp() allows 1-click restarting directly into the newly updated version.
  • VS Code Style Post-Update Release Notes Tab:
    • Automatically opens a dedicated rendered Release Notes tab upon first launch after an update, showing the changelog and highlights.
    • Tracked via localStorage to ensure it is displayed only once per version update.
    • Seamlessly integrated as an editor tab (termlet://release-notes) alongside file and settings tabs.
    • Can be reopened at any time from the Settings view via the "Release Notes" button.
  • Settings Integration: direct "Check for Updates" and "Install Update" triggers right inside the Settings view and bottom status bar.

🪟 Windows Native Icon & Taskbar Integration

• Multi-Resolution Windows Executable Icon:
  • Generated and embedded a true multi-resolution icon (build/windows/icon.ico) with standard 16x16, 32x32, 48x48, 64x64, 128x128, and 256x256 RGBA layers.
  • Fixes icon display across Windows Taskbar, Alt-Tab task switcher, File Explorer detail/tile views, and the window title bar.
  • Resolved missing custom icon issue in NSIS installer setup wizard and Start Menu application shortcuts.
• Master App Icon Standardization:
  • Re-rendered build/appicon.png into a crisp 512x512 RGBA squircle asset with smooth antialiased corners for cross-platform packaging.

🌐 Webview & Browser Favicon Assets

• Webview Favicon Support:
  • Added frontend/public/favicon.png (512x512) and frontend/public/favicon.ico (multi-res 16/32/48).
  • Explicitly linked <link rel="icon" type="image/png" href="/favicon.png" /> in frontend/index.html to eliminate blank or default webview icons during runtime.
  • Added clean <title>Termlet</title> branding in the webview document head.

🎨 Complete Light Mode UI & Contrast Polish

• Remote File Tree Readability:
  • Enhanced text color contrast in light mode: unselected tree items now use high-contrast dark text (text-zinc-800 / hover:text-zinc-950) instead of low-contrast muted zinc.
  • Polished active item highlight: replaced low-contrast white highlight with a crisp, subtle blue badge (bg-blue-100 text-blue-900 in light mode, bg-blue-900/30 text-blue-200 in dark mode).
  • Ensured toolbar button icons (Refresh, Collapse All) adopt high-contrast foreground states in both themes.
• Code Editor Canvas & Status Bar:
  • Fixed empty editor background: eliminated the jarring dark canvas in light mode when no files are open, seamlessly adopting a clean bg-zinc-50 backdrop with dark zinc prompt text.
  • Seamless Status Bar: synchronized the bottom status bar background (bg-zinc-100/90 text-zinc-700) and border color to match the light theme workspace.
• SSH Connection Dialog:
  • Overhauled modal styling: resolved harsh dark panels in light mode by applying appropriate light theme containers (bg-white/95 text-zinc-800 border-zinc-200).

🎛️ Linux WebKitGTK Spinner Elimination

• Numeric Stepper Polish:
  • Fully suppressed native WebKitGTK number spin boxes in connection dialog port inputs and settings panels, providing clean, tactile, custom stepper buttons across all platforms.
