# POPO

Define everything using POPOs (Plain Old Python Object), then you can easily use it from SQLAlchemy ORM, Protobuf3, and so on.

## Wanted Goals

- Python 3

- $ popo input.py

	- -> input.sqla.py

	- -> input.proto

- POPO input files just work as normal python file

- Pipeline:

	- Read Input

	- Convert to Own DataTypes

	- Target Factories

	- Outputs

## Wanted Types

- [Python Default Types](https://docs.python.org/3/reference/datamodel.html#the-standard-type-hierarchy)

	- Numeric thingy: Integer, Float, Double, ...

	- String

	- List

	- Bytes

- [DateTime](https://docs.python.org/3.5/library/datetime.html#datetime.datetime.now)

- Enum

- ...

## Wanted Targets

- [SQLAlchemy ORM](http://www.sqlalchemy.org/)

- [Protobuf](https://developers.google.com/protocol-buffers/docs/proto3#scalar)

- ...

## Wanted Features

- Versioning

	- SQLAlchemy will cover this by alembic

	- Protobuf need to consider this

		- read olders and managing the 

- Targets Factory and Configurable Targets? (custom type converter?)

	- want to export with

		- [sqlalchemy-utils](https://github.com/kvesteri/sqlalchemy-utils)

		- [protobuf3](https://github.com/Pr0Ger/protobuf3)

- Prefix/Postfix naming

- ...

## Resolved Question

- [PEP 484 - Type Hints](https://www.python.org/dev/peps/pep-0484/)?

	- Nope, it's not for class defining.

- [How to get parse tree of python?](http://python3porting.com/fixers.html)

	- ast: "designed to generate an abstract syntax tree and ignores all comments and formatting"

	- parser: "internal code parser, which is optimized to generate byte code and too low level"

	- lib2to3: "high level and contains all formatting, but that doesn’t mean it’s easy to use"

		- Why don't you just make 2to3 fixer for converting those?

			- I don't think 2to3 is not for it.

		- how to get the parse tree form lib2to3?

			- lib2to3.pgen2, but it's for python2 (maybe)

				- oops, our target is python3

	- yo yo yo yo yo!!! We don't need to parse! We just used class.

		- So Class.__dict__() and instanceof() will cover all.

			- really? dive it now!

				- import `popo-input`

					- I want cli, but how to import `/path/popo-input.py`?

						- just use `popo-input` and see you next time.

						- I found `modulefinder`, is it related?

				- dir(`popo-input`)

					- ignore `__.*__`

				- .\_\_dict\_\_

					- ignore `__.*__`

				- .

## Unresolved Questions

- Is really needed? helpful?

- How to ...

	- save datetime @ protobuf?

		- maybe timestamp and timezone.

	- manage the build?

	- name exported output?

	- limit the type of contents?

	- limit the size of string with this?

		- using comment? (noooooooooo..)

		- using 

	- manage the metadata of input/output source code?

		- why need it?

			- ...

- Where is the gap for adding versioning process.

- No Private / Forgien Key?!

- Nested Class!

- Alphabetical Order Class Contents?!!!

- How to save the order of input, and keep it as output?!!!!!!!!!! <- currently biggest mission blocker (lib2to3 needed?)

## TODO

- .gitignore

## Milestone

1. Set the clear blueprint for v0.0.0 (due: 151115)

	- minimum wanted-types: 

		- integer

		- string

		- ?

	- 2 targets

		- sqlalchemy

		- protobuf

	- 1 feature

		- target factory

	- Goal: directory design

	- Goal: pipeline design

2. ...
