hslua: A Lua language interpreter embedding in Haskell

[ foreign, library, mit ] [ Propose Tags ]

The Foreign.Lua module is a wrapper of Lua language interpreter as described on lua.org.

This package contains a full Lua interpreter version 5.3.4. If you want to link it with a system-wide Lua installation, use the system-lua flag.

Example programs are available in a separate repository.

Automatic Flags

Use the system-wide Lua instead of the bundled copy.


Compile Lua with -DLUA_USE_APICHECK.


Link with LuaJIT. This implies flag system-lua as well.


Build against lua 5.1.


Build against lua 5.2.


Build using pkg-config to discover library and include paths. This is only used with system-lua and luajit.


Use -f <flag> to enable a flag, or -f -<flag> to disable that flag. More info

hslua – Lua interpreter interface for Haskell

Build Status Coverage Status Hackage

Hslua provides bindings, wrappers, types, and helper functions to bridge haskell and lua.

Using a different lua version

To use system-wide installed Lua/LuaJIT when linking hslua as a dependency, build/install your package using --constraint="hslua +system-lua" or for LuaJIT: --constraint="hslua +system-lua +luajit". For example, you can install Pandoc with hslua that uses system-wide LuaJIT like this:

cabal install pandoc --constraint="hslua +system-lua +luajit"


Where are the coroutine related functions? Yielding from a coroutine works via longjmp, which plays very badly with Haskell's RTS. Tests to get coroutines working with HsLua were unsuccessful. No coroutine related functions are exported from the default module for that reason. However, raw bindings to the C API functions are still provided in Foreign.Lua.RawBindings. If you get coroutines to work, or just believe that there should be wrapper functions for other reasons, we'd love to hear from you.
