1. fromBool :: Num a => Bool -> a

   ghc-internal	GHC.Internal.Foreign.Marshal.Utils

   Convert a Haskell Bool to its numeric representation

2. toBool :: (Eq a, Num a) => a -> Bool

   ghc-internal	GHC.Internal.Foreign.Marshal.Utils

   Convert a Boolean in numeric representation to a Haskell value

3. pattern LUA_TBOOLEAN :: TypeCode

   lua	Lua

   Type of Lua booleans

4. newtype LuaBool

   lua	Lua

   Boolean value returned by a Lua C API function. This is a CInt and should be interpreted as False iff the value is 0, True otherwise.

5. LuaBool :: CInt -> LuaBool

   lua	Lua

   No documentation available.

6. lua_isboolean :: State -> StackIndex -> IO LuaBool

   lua	Lua

   Returns TRUE if the value at the given index is a boolean, and FALSE otherwise. https://www.lua.org/manual/5.4/manual.html#lua_isboolean

7. lua_pushboolean :: State -> LuaBool -> IO ()

   lua	Lua

   Pushes a boolean value with the given value onto the stack. https://www.lua.org/manual/5.4/manual.html#lua_pushboolean.

8. lua_toboolean :: State -> StackIndex -> IO LuaBool

   lua	Lua

   Converts the Lua value at the given index to a haskell boolean value. Like all tests in Lua, toboolean returns True for any Lua value different from *false* and *nil*; otherwise it returns False. (If you want to accept only actual boolean values, use lua_isboolean to test the value's type.) https://www.lua.org/manual/5.4/manual.html#lua_toboolean

9. pattern LUA_TBOOLEAN :: TypeCode

   lua	Lua.Constants

   Type of Lua booleans

10. lua_isboolean :: State -> StackIndex -> IO LuaBool

    lua	Lua.Primary

    Returns TRUE if the value at the given index is a boolean, and FALSE otherwise. https://www.lua.org/manual/5.4/manual.html#lua_isboolean
