what about decorator?!

[minhoryang]

Mock

class Test:
  name = ""  # RULES: limitrange(10,20)

-> lib2to3.pgen2

Converted

from popo import String

class _Test_Mock:
  def __init__(self):
    String(self, "name", "", {"limitrange": ((10, 20), {})})

if __name__ == "__main__":
  Generate(_Test_Mock)

is equivalent to (and works as)

class _Test_Mock:
  def __init__(self):
    self._name = ""

  @property
  def name(self):
    return self._name

  @limitrange(10, 20)
  @name.setter
  def name(self, value):
     self._name = value

Usage:

class Test(_Test_Mock):
  def __init__(self, blah, blah):
    super.__init__(self)

for SQLAlchemy

What if replacing this

from popo import String, Generate

to

from popo.ext.sqlalchemy import String, Generate

Run it, then this will be generated.

class TestMixIn(object):
  name = db.Column(db.String(20))

Usage:

class Test(TestMixIn, db.Model):
  __tablename__ = "test"
