Creates a module. If there is a table in package.loaded[name]
, this table is the module. Otherwise, if there is a global table t
with the given name, this table is the module. Otherwise creates a new table t
and sets it as the value of the global name
and the value of package.loaded[name]
. This function also initializes t._NAME
with the given name, t._M
with the module (t
itself), and t._PACKAGE
with the package name (the full module name minus last component; see below). Finally, module
sets t
as the new environment of the current function and the new value of package.loaded[name]
, so that require (modname)
returns t
.
If name
is a compound name (that is, one with components separated by dots), module
creates (or reuses, if they already exist) tables for each component. For instance, if name
is a.b.c
, then module
stores the module table in field c
of field b
of global a
.
This function may receive optional options after the module name, where each option is a function to be applied over the module.
