The most Customary way for development in Pashmak project, is Developing builtin modules. A bug part of Pashmak is the builtin modules, not interpreter core.
For example, os, sys… are builtin modules.
Source code of them are in src/<module-name>/.
For example, when we import os(import @os), Source code of that is in src/os/__init__.pashm.
Also when you import sys.path, source code is src/sys/path.pashm.
Totally, when we import foo.bar.baz, we are importing src/foo/bar/baz.pashm or src/foo/bar/baz/__init__.pashm.
If you want to add a module, create a directory with name of module. for example src/mymodule. Then, under the above structure, put the files.
After changing/adding a module, you should run make module or make all to mix them. Mixing the modules means that puting content of this pashmak scripts into file src/core/modules.py To be accessible by interpreter core as a python file.
If you are adding a new module, surely write your code inside a namespace. for example, if you created mymodule, write your code between namespace mymodule ... endns. This makes modules splited.
Stdlib or Standard library, is a very important modules. Some functions/classes/etc in Pashmak are accessible without importing any module. They are in stdlib. stdlib is a module like all of other modules, But will be imported by default while program starts.
Content of this is in src/stdlib/.
Also content of this module is seprated in several files.
(For example stdlib.obj, stdlib.func…).
