Clone a Module.

Clone a module.

clone(name, from_name, deep = FALSE)

Arguments

name	A string (character vector of lenght one). A module name can contain letters, figures and some special characters, namely _, -, and /. The latter is a namespace separator. Names containing /mock/, /mocks/, /test/, /tests/, /example/, or /examples/ have a special meaning related to code testing and examples. The name "modulr" corresponds to a special module and is therefore reserved.
from_name	Name of module to clone.
deep	A flag. Should the entire register entry be cloned?

Value

A wrapper function around a make call for the defined module.

Details

For versioning purposes, it is often useful to clone modules.

Warning

It is considered a very bad practice to define, touch, undefine, load, make, reset, or perform any other operation from within a module definition that may alterate the internal state of modulr.
