v1.9.311

Bug Fixes

• SDLXLIFF export: fix missing translations for self-closing mrk segments — When Trados SDLXLIFF files contained self-closing <mrk mtype="seg" mid="N" /> tags in the <target> element (used for empty/untranslated segments), Supervertaler's export would silently skip them because the regex only matched the open+close form. This caused translated segments to appear empty when re-opened in Trados Studio. The export now handles both forms correctly via a second replacement pass for self-closing tags.

v1.9.285

What's new

• Import folder of SDLXLIFF files (issue #80) — A new Import → Trados Studio → Bilingual XLIFF Folder (.sdlxliff)... menu item lets you point Supervertaler at a folder and automatically import all .sdlxliff files found inside it, including those in subfolders. This covers the common workflow where clients send a directory of SDLXLIFF files instead of a packaged .sdlppx. After translating, export all files back via Export → Trados Studio → Bilingual XLIFF - Translated (.sdlxliff)... as usual.

v1.9.276 - Fix SQLite database locking, fix macOS Finder launch crash

🍎 macOS Users: Important First-Launch Instructions

macOS may block Supervertaler from opening because it is not signed with an Apple Developer certificate. To allow it to run:

1. Double-click Supervertaler.app — macOS will show a warning that it "can't be opened"
2. Open System Settings → Privacy & Security
3. Scroll down to find the message about Supervertaler being blocked
4. Click "Open Anyway"
5. Confirm when prompted — Supervertaler will now launch normally every time

You only need to do this once.

---

Bug Fixes

• Fixed SQLite "database is locked" errors during termbase operations — Activating, deactivating, or changing read-only status of termbases would intermittently fail. Enabled WAL journal mode and 15-second busy timeout on all SQLite connections, and added rollback on error to release locks after failed commits.
• Fixed macOS Finder launch crash — Removed leftover debug file writes (theme_debug.txt, superlookup_debug.txt) that crashed the app with OSError: Read-only file system when launched from Finder (where CWD is /).

What's Changed

Bug Fix

• Fix macOS Finder launch crash - App worked from Terminal but bounced/crashed when double-clicked in Finder. Root cause: macOS Finder launches apps with minimal environment (no LANG/LC_CTYPE), causing locale-dependent code to fail silently. Fixed by adding LSEnvironment to Info.plist setting LANG and LC_CTYPE to en_US.UTF-8.
• Add macOS crash logging - When launched as a frozen .app on macOS, diagnostic info is written to ~/Desktop/supervertaler_crash.log to aid debugging Finder-specific launch issues.

v1.9.274

Bug Fixes

• TM matches now shown consistently when revisiting segments - The Match Panel (TM Source/Target boxes) showed TM hits only on the first visit to a segment. On revisit, the cached results were displayed in the Translation Results panel but the Match Panel was not updated. Fixes #164.
• Find & Replace: uppercase history no longer overwrites lowercase input - The auto-completer on the F&R input fields matched case-insensitively, so previously searched uppercase terms (e.g. COMMISSIONING) would overwrite lowercase input. Disabled the completer; dropdown history remains accessible via the arrow button. Fixes #163.
• Standalone builds now show the correct version number - PyInstaller .exe builds always displayed a stale fallback version because pyproject.toml was not bundled. Now bundled in both Windows and macOS builds. Also added importlib.metadata fallback for pip installs, fixed create_release_zip.py version extraction, and made macOS CFBundleVersion dynamic. Fixes #165.

pip: pip install --upgrade supervertaler

Windows standalone: Download the ZIP below, extract, and run Supervertaler/Supervertaler.exe.

Supervertaler v1.9.255

Supervertaler v1.9.255

Professional AI-enhanced translation workbench with multi-LLM support (GPT-4, Claude, Gemini, Ollama), translation memory, glossary management, and seamless CAT tool integration (memoQ, Trados, CafeTran, Phrase, Déjà Vu).

What's New (v1.9.250 – v1.9.255)

New Features

• QuickTrans pastes translation at cursor — Invoke QuickTrans (Ctrl+Alt+M / ⌃⌘M) from any app, pick a translation, and it's pasted right where your cursor was — replacing the selected text. Works in Chrome, Trados, text editors, everywhere.
• Copy Source to Target works on multi-selection — Select multiple segments (Ctrl+Click / Shift+Click), press Ctrl+Shift+S (Cmd+Shift+S on Mac), and all selected segments get their source copied to target at once. (#141)

Cross-Platform (macOS & Linux)

• macOS global hotkeys — Superlookup (⌃⌘L) and QuickTrans (⌃⌘M) now work natively on macOS via pynput.
• Accessibility permission guidance — Clear instructions when macOS blocks hotkey registration.
• macOS build support — New BUILD_MACOS.md guide and Supervertaler_macOS.spec for building a native .app bundle.

Bug Fixes

• Superlookup window focus — Ctrl+Alt+L now reliably brings Supervertaler to the foreground from any app (Windows, macOS, Linux).
• QuickTrans no longer flashes taskbar — Uses Tool window type when invoked via global hotkey.
• Trados bilingual self-closing tags — Tags like <255/> are now exported correctly with the Tag character style; no more tag errors on Trados re-import.
• TM/Glossary preselection cleared on new project — Previous project's TM and glossary checkboxes no longer carry over.
• Trados Bilingual Review dialog — Corrected preparation instructions for segment selection and file renaming.
• macOS shortcut labels — Settings now show correct ⌃⌘ (Ctrl+Cmd) instead of ⌘⌥ (Cmd+Option).

What's New in v1.9.204

Bug Fixes

DOCX Export Improvements

• Font Preservation: Fixed an issue where exported DOCX files would lose the original font name (e.g., Verdana) and font size (e.g., 10pt). The export now correctly preserves font properties from the original document.

• All Caps Preservation: Fixed an issue where text with the "All Caps" font effect (like patent titles) would export in normal case instead of uppercase. The all_caps font property is now preserved.

• Subscript/Superscript Support: Fixed an issue where <sub> and <sup> formatting tags were not being processed during export. Text like "CO₂" now correctly exports with subscript formatting.

• Partial Replacement Formatting: Fixed an issue where paragraphs containing multiple segments would lose all inline formatting (bold, italic, subscript, superscript) during export. Partial replacements now properly apply formatting tags.

UI Improvements

• Export Menu Reorganization: Moved monolingual export formats to the top of the Export menu for easier access:
  • Target Only (DOCX)
  • Simple Text File - Translated (TXT)
  • AI-Readable Markdown (.md)
  • ─────────────────
  • [Bilingual CAT tool formats below]

🚀 What's New in v1.9.183

⚡ Major Performance Improvements: Instant Navigation

The big one: Ctrl+Enter navigation is now instant instead of taking 10-50+ seconds per segment.

In-Memory Termbase Index

• Pre-indexed, in-memory glossary lookup system replaces per-segment database queries
• Glossary lookups now take <1ms instead of 52 seconds per segment
• Index is built once when project loads (~0.15s for 1,400 terms) and updated instantly when terms are added
• 95%+ cache hit rate after initial segment visit

Async Auto-Confirm

• The "auto-confirm 100% TM matches" feature now runs asynchronously
• Navigation completes instantly; TM lookup happens in the background
• If a 100% match is found, the segment is auto-confirmed after you've already moved

Cache System Enabled by Default

• Prefetch cache is now enabled by default for new installations
• Background workers pre-cache termbase and TM matches for upcoming segments
• Massive performance improvement out of the box

🐛 Bug Fixes

• TermView Updates on Ctrl+Enter: The glossary/terminology panel now updates immediately when navigating with Ctrl+Enter, not just on mouse click

• TM Panel Updates on Ctrl+Enter: Translation Memory matches now appear immediately when navigating with Ctrl+Enter

• Source Text Always Visible: TermView now displays the source text even when there are no glossary matches, with appropriate status messages ("No matches in X words", "No glossaries activated", etc.)

• Row Selection on Ctrl+Enter: The target row is now properly selected (blue highlight) after Ctrl+Enter navigation

• TM Results for Correct Segment: Fixed race condition where fast navigation could show TM results for the wrong segment; added segment validation before and after TM lookup

• TM Lookup on Cache Hit: Fixed issue where TM matches weren't shown when termbase was cached
