Mastering LuaJIT (Paperback)

Paperback. Master LuaJIT and Push Dynamic Scripting to C-Level PerformanceMastering LuaJIT is a deep, authoritative guide to building high-performance Lua applications using LuaJIT's trace-based JIT compiler, advanced optimization techniques, and zero-overhead C integration via the FFI.Designed for experienced developers, systems engineers, and performance-focused programmers, this book reveals how LuaJIT achieves execution speeds that rival optimized C and how you can write JIT-compliant Lua code that consistently stays on the fast path.What You'll LearnHow LuaJIT's trace compiler works internally hot loops, guards, side exits, and trace stitchingBytecode internals, virtual registers, stack frames, and execution flow analysisWriting high-performance Lua scripting code that avoids NYI abortsAdvanced LuaJIT optimization techniques used in games, networking, and real-time systemsUsing the Lua FFI for direct C integration with near-zero overheadZero-copy data structures, manual memory management, and GC pressure reductionProfiling and debugging LuaJIT using jit.dump, jit.v, and system profilersEmbedding LuaJIT in C/C++ applications and managing multi-threaded executionAdvanced Topics CoveredTrace-based JIT vs method-based JIT compilationNaN tagging, GC64 mode, and memory layout optimizationsRegister allocation and machine code generationFFI callbacks, C structs, bitfields, and ABI alignmentOptimizing LuaJIT for game development and real-time enginesHigh-throughput scripting with OpenResty LuaJIT and NginxPlatform-specific tuning for x86-64 and ARM64 systemsThis book is ideal for: Lua developers seeking maximum performanceGame developers using LuaJIT in real-time enginesSystems programmers interested in compiler internalsBackend engineers using OpenResty LuaJIT at scaleDevelopers embedding LuaJIT into native C or C++ applicationsIt assumes familiarity with Lua and basic C concepts. This is not an introductory Lua book, it is a performance engineering manual for developers who want to understand what the JIT compiler is really doing.LuaJIT is more than a faster Lua interpreter. It is a carefully engineered runtime that combines: A hand-written assembly interpreterA trace-based JIT compiler optimized for hot execution pathsA revolutionary Foreign Function Interface (FFI)When used correctly, LuaJIT enables low-latency scripting, deterministic performance, and seamless native integration making it a powerful tool for modern systems programming.Mastering LuaJIT gives you the mental model, tools, and techniques needed to write Lua code that the JIT compiler loves transforming scripts into production-grade, high-performance systems.If you want to understand how LuaJIT really works and how to make it work for you this book is your definitive guide.Author: Lucas Wallace This item is printed on demand.
