Description

Utility functions for HsLua modules.

Synopsis

- requirehs :: LuaError e => Name -> (Name -> LuaE e ()) -> LuaE e ()
- preloadhs :: LuaError e => Name -> LuaE e NumResults -> LuaE e ()

# Documentation

requirehs #

Arguments

:: LuaError e |
=> Name | modname
-> (Name -> LuaE e ()) | openf
-> LuaE e () |

Load a module, defined by a Haskell action, under the given name.

Similar to `luaL_requiref`: If `modname` is not already present in `package.loaded`, calls function `openf` with string `modname` as an argument and sets the call result in `package.loaded[modname]`, as if that function has been called through require.

Leaves a copy of the module on the stack.

preloadhs :: LuaError e => Name -> LuaE e NumResults -> LuaE e () #

Registers a preloading function. Takes an module name and the Lua operation which produces the package.
