Neko Launcher (NekoLc) is a modern, cross-platform, multi-language launcher with built-in auto-update. It can launch arbitrary targets; the current template ships with Minecraft: Java Edition support. It can update both your content and Neko Core, install assets automatically, and present a customizable UI.

Preview:

Features

• Auto-update pipeline for both the launcher and your distributed content
• Cross-platform Qt UI with theme, font, and language customization
• Template for launching Minecraft: Java Edition; extensible to other targets
• Built-in dialogs for notices, inputs, and progress/loading states

Requirements

• CMake 3.20+ and a C++20 compiler (MSVC/Clang/GCC)
• Qt 6 (Widgets + Gui + Core); Qt 5.15+ may work but is untested
• Git (for submodules) and internet access for dependency fetch during configure

Quick Start (desktop)

# Clone
git clone https://github.com/moehoshio/NekoLauncher.git
cd NekoLauncher

# Configure
cmake -B build -DNEKO_LC_LIBRARY_PATH="<Qt_path>;<Package_path>" -DNEKO_LC_STATIC_LINK=ON -S .

# Build (Debug|Release)
cmake --build build --config Release

# Run
./build/Release/NekoLc.exe

For other toolchains, replace the generator/commands accordingly. Set NEKO_LC_LIBRARY_PATH if Qt is not auto-detected.

Configuration

• config.ini.example shows available options; copy it to config.ini and adjust paths, background, and update endpoints.
• Language files live in lang/; images live in resource/img/.

Contributing

• Templates: additional launch targets beyond Minecraft
• QoL: drag-and-drop layout customization, optional music playback, more tests
