[ANN] OneLuaPro 5.4.8.3 – Event-driven Multi-threading and SQLite3+sqlean Integration

[Kritzel Kratzel]

Hi everyone,

OneLuaPro 5.4.8.3 has been released. This update introduces significant changes to the internal handling of asynchronous tasks and provides native database capabilities.

Downloads: https://github.com/OneLuaPro/OneLuaPro/releases/tag/v5.4.8.3

Technical Updates:

• wxLanesBridge Implementation: Support for multi-threaded GUI applications is now facilitated by the wxLanesBridge module. This component bridges the gap between wxLua and Lua Lanes. The traditional bottleneck of timer-based polling has been eliminated; instead, an event-driven approach is utilized where worker threads communicate directly with the main GUI thread via postEvent(). This ensures immediate UI responsiveness and reduced CPU overhead.

• DistroCheck Tool: A new utility for verifying distribution integrity is included. Developed as a reference implementation for wxLanesBridge, it demonstrates how intensive I/O operations can be offloaded to worker threads without blocking the wxLua event loop. The implementation details and the postEvent() signaling logic can be examined in the OneLuaPro distro repository.

• OneLuaPro Help Center: Centralized documentation is now available through a dedicated Help Center, serving as the primary hub for all technical documentation.

• SQLite3 + sqlean Integration: Database support is provided via a reimplementation of lsqlite3, utilizing the most recent SQLite3 builds. Notably, the full suite of sqlean extensions (e.g., crypto, fileio, math, text) is integrated, providing a comprehensive set of functions for advanced data manipulation directly within SQL.

• Executables: All former .bat files within the bin/ directory have been replaced by native executables to ensure cleaner process handling and user experience.
