hslua – Lua interpreter interface for Haskell

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"

(Note that -fluajit flag is added with hslua 0.3.14)

Changes

Changelog

0.4.1

Bugfix(#30): tolist wasn’t popping elements of the list from stack.

0.4.0

pushstring and tostring now uses ByteString instead of [Char].
StackValue [Char] instance is removed, StackValue ByteString is added.
StackValue a => StackValue [a] instance is added. It pushes a Lua array to the stack. pushlist, islist and tolist functions are added.
Type errors in Haskell functions now propagated differently. See the Scripting.Lua documentation for detailed explanation. This should fix segfaults reported several times.
lua_error function is removed, it’s never safe to call in Haskell.

0.3.14

Pkgconf-based setup removed. Cabal is now using extra-libraries to link with Lua.
luajit flag is added to link hslua with LuaJIT.

0.3.13

Small bugfix related with GHCi running under Windows.

0.3.12

pushrawhsfunction and registerrawhsfunction functions are added.
apicheck flag is added to Cabal package to enable Lua API checking. (useful for debugging)

0.3.11

luaL_ref and luaL_unref functions are added.
