Hi all,
I'm having some issues calling Lua functions from Haskell. I have the
following in "Haskell2Lua.lua":
function hello ()
return "hello world"
end
And my Haskell file "Haskell2Lua.hs" looks like this:
import qualified Scripting.Lua as
Lua
main =
do
l <-
Lua.newstate
Lua.openlibs
l
succ <- Lua.loadfile l
"/Haskell2Lua.lua"
print succ
Lua.callproc l "hello"
""
Lua.close l
When I compile and run this file I get:
0
Haskell2Lua: user error (attempt to call a nil value)
I have tried some variations on calling the function including:
Lua.callproc l "hello"
Lua.callfunc l "hello"
Lua.callfunc l "hello" ""
I know the Lua bridge is working because the following works:
Lua.callproc l "print" "Hello from Lua"
Any help is appreciated!
