寻求可打包适配LuaJIT的便携正则表达式库（开箱即用无需安装）

Hey there! Since you're building a portable LuaJIT app and need PCRE/PCRE2-style regex support (without Lpeg), here are the best self-contained options that can be bundled with your source, interpreter, and app into a single, ready-to-run package:

1. lj2pcre (LuaJIT + PCRE2 FFI Binding) #

• Why it fits: This is a lightweight FFI-based binding for PCRE2, built specifically for LuaJIT. It supports full PCRE2 syntax, and crucially, you can compile it to statically link the PCRE2 library directly into your LuaJIT executable.
• Portability on Windows:
  • Compile using MinGW or MSVC to create a single .exe that includes LuaJIT, your script, and the PCRE2 regex logic. No separate DLLs required—users just run the exe and go.
  • If you don’t want to compile from source, you can find pre-built static binaries for Windows that work out of the box.
• Usage example:

  local pcre = require("lj2pcre")
  local match = pcre.match("Hello World", "Hello (\\w+)")
  print(match[1]) -- Outputs "World"
  

2. Statically Linked rex_pcre #

• Why it fits: rex_pcre is a widely used Lua binding for PCRE, and when statically linked against PCRE and LuaJIT, it eliminates external dependencies.
• Windows bundling:
  • Grab a pre-compiled static rex_pcre.dll (or compile your own) and bundle it alongside your LuaJIT interpreter and script.
  • Use tools like Enigma Virtual Box or 7-Zip SFX to package all files into a single self-extracting executable. When run, the tool extracts the files to a temporary directory, runs your app, and cleans up afterward—completely transparent to the user.
• Key note: Make sure you use the static build of rex_pcre (not the dynamic one that relies on system PCRE libraries) to avoid missing DLL errors.

3. LuaJIT-Regexp (Pure LuaJIT Bytecode, PCRE-Like) #

• Why it fits: If you want something that doesn’t require compiling C code, this library implements a PCRE-compatible regex engine entirely in LuaJIT-optimized bytecode. It’s slower than native PCRE bindings but works without any external C dependencies.
• Portability: Just drop the .lua file into your project, require it, and bundle it with your other files. No DLLs or compilation needed—perfect for quick, portable setups.

Pro Tips for Windows Portability #

• Always test your bundled app on a fresh Windows machine (no Lua or PCRE installed) to ensure there are no hidden dependencies.
• For single-file deployment, tools like srlua or luajit-srlua can compile your Lua script and the required libraries into a standalone LuaJIT executable—great for keeping things clean.
