XTranslate ✦

XTranslate is a modern, lightweight, and blazing-fast desktop translation tool for Windows, inspired by QTranslate. Designed with WPF and .NET 8, it offers an exceptionally smooth translation experience right at your fingertips.

🚀 Key Features

• ⚡ Instantly Translate Anywhere: Highlight text in any application and press your configured hotkey to instantly view translations. No more copying and pasting into browser tabs!
• 🖱️ Smart Floating Popup: Press Ctrl + Q to open a sleek, transparent translation popup near your cursor. It automatically disappears when you click outside or returns focus to your work.
• 🖥️ Detailed Main Window: Press Ctrl + Enter to open a broader window for editing lengthy translations, checking character counts, and browsing complete translation outputs.
• 🧠 Intelligent Auto-Language Flipper: Uses advanced context awareness! If your Target Language is Vietnamese and you highlight a Vietnamese sentence, XTranslate will automatically flip the Target Language to English and translate seamlessly.
• 🔀 Quick Language Swapping: Integrated UI buttons let you reverse the Source and Target languages with a single click in both the Main and Popup windows.
• 🌙 Dark Mode First: Features a modern, aesthetically pleasing Dark UI with glassmorphism effects, ensuring zero eye strain during late-night coding or reading sessions.
• ⚙️ Multi-Engine Support: Built to support multiple translation engines. Currently powers translations via MyMemory, with an extensible architecture ready for Google, Bing, and DeepL integrations.

⌨️ Default Hotkeys

• Ctrl + Q: Activate Floating Popup Translation.
• Ctrl + Enter: Open Detailed Main Translation Window.
• Esc: Close open windows instantly.

📦 Deployment & Binaries

XTranslate is highly optimized and distributed in two deployment formats.

Run the included build.ps1 script to generate outputs:

• Lightweight Build (~5MB): Ultra-fast executable. Requires the .NET 8 Desktop Runtime installed on your target machine.
• Standalone Build (~68MB): Fully self-contained. Runs on any Windows machine immediately, without requiring users to download or install any framework.

Outputs are generated in PublishOutput/Lightweight/ and PublishOutput/Standalone/ respectively.

🛠️ Internal Architecture

Built with best practices using the MVVM pattern in C# and WPF Windows Presentation Foundation:

• Windows API: Leverages Global Keyboard Hooks (SetWindowsHookEx) to listen for hotkeys globally across applications.
• SendKeys API: Automates system clipboard interaction (^c) for blazing-fast 10ms text capturing from other active windows without blocking the UI thread.
• Dependency Injection: Strictly follows SOLID principles with Autofac for service encapsulation.
