LuaJIT LPeg Module

This is a custom build of the LPeg library for LuaJIT on macOS, using FFI for loading.

Installation

  1. Copy lpeg.lua and lpeg_ffi.so to your Lua package path (e.g., /usr/local/lib/lua/5.1/ or a local directory).
  2. Ensure both files are in the same directory.

Usage

local lpeg = require("lpeg")
-- Use lpeg functions as usual

API

The module exposes the standard LPeg API. See the official documentation for details.

Key Functions

  • lpeg.match(pattern, subject [, init]): Matches a pattern against a string.
  • lpeg.P(value): Converts a value into a pattern.
  • lpeg.R(range): Matches a range of characters.
  • lpeg.S(set): Matches any character in a set.
  • lpeg.C(pattern): Captures the match.
  • lpeg.Ct(pattern): Captures the match as a table.

Build

To build the shared library from source:

gcc -O2 -bundle -undefined dynamic_lookup -I/opt/homebrew/include/luajit-2.1 -o lpeg_ffi.so lpeg-src/*.c

Notes

  • The build command assumes you have LuaJIT installed in /opt/homebrew/include/luajit-2.1. Adjust the path if your LuaJIT installation is in a different location.
  • This build is specifically for macOS. For other platforms, you may need to adjust the build flags.
