Elixir Language Modules Using modules
Example
Modules have four associated keywords to make using them in other modules: alias, import, use, and require.
alias will register a module under a different (usually shorter) name:
defmodule MyModule do
# Will make this module available as `CoolFunctions`
alias MyOtherModule.CoolFunctions
# Or you can specify the name to use
alias MyOtherModule.CoolFunctions, as: CoolFuncs
end
import will make all the functions in the module available with no name in front of them:
defmodule MyModule do
import Enum
def do_things(some_list) do
# No need for the `Enum.` prefix
join(some_list, " ")
end
end
use allows a module to inject code into the current module - this is typically done as part of a framework that creates its own functions to make your module confirm to some behaviour.
require loads macros from the module so that they can be used.
