Modules / Namespaces

[xNaCly]

Idea

As proposed some time ago in examples/modules.phia.

Modules will be used to group functions together and enable the linking of the standard library via wrappers.

Sophia/examples/modules.phia

Lines 18 to 24 in 3b148ea

	(module person
	(fun str [p] (++ "person: " p#["name"])
	(module extract ;; namespaces can be nested
	(fun name (_ p) p["name"])
	)
	)

Calling functions of a given module:

Sophia/examples/modules.phia

Lines 26 to 33 in 3b148ea

	;; using a custom module
	(use person)
	(let pers { name: "anon" })
	(println (person::string pers))
	;; using nested module
	(use person::extract)
	(println (person::extract::module pers))

Implementation details:

1. Modules will be registered with its name upon encountering (module <name>) in consts.MODULE_TABLE via the expr.Module.Eval() structure
2. Encountering (use <module>) will evaluate the module and place its functions into the consts.FUNC_TABLE prefixed with <module_name>::.
3. Calling the function via (<module>::<function> <args) is now possible
