Greetings!

I am attempting to get 'test.py' (https://www.thanassis.space/asn1.html) working w/ sqlalchemy.

However, I keep running into this issue:

sqlalchemy.exc.OperationalError: (sqlite3.OperationalError) table Message has no column named fk_msgId_iid [SQL: u'INSERT INTO "Message" ("fk_msgId_iid", fk_myflag_iid, fk_value_iid, "fk_szDescription_iid", "fk_isReady_iid") VALUES (?, ?, ?, ?, ?)'] [parameters: (1, 1, 1, 1, 1)] (Background on this error at: http://sqlalche.me/e/e3q8)

I keep running into this error (lack of fk_*_iid column) under a variety of examples.
It seems to be a mismatch between sqlalchemy definitions and the generated schema.
I have attempted this with postgres as well.

I was hoping you could provide some insight. Let me know if you need more information. I attempted to sign up for the mailing list but haven't received confirmation yet.

Extremely interesting project! Thanks in advance.

The build as described in README.md does not lead to a functional install on either Windows or Linux, in exactly the same way. Using Python 3.8:

PS C:\Users\Emil\Documents\tools\DataModellingTools> pip3 install --user --upgrade .
ERROR: Directory '.' is not installable. Neither 'setup.py' nor 'pyproject.toml' found.

Practically the same message on ubuntu 20.04 LTS with Python 3.9. When I rename setup.py.in to setup.py, I am able to install it, but run into this issue, which I solved by manually installing mypy. Still, I get this in install:

\site-packages\setuptools\dist.py:472: UserWarning: The version specified ('2.2-@SCM_REVISION@') is an invalid version, this may not work as expected with newer versions of setuptools, pip, and PyPI. Please see PEP 440 for more details.

So it's installing with a non-expanded version macro in the name. But that at least doesn't break the whole thing. Now when I run asn2datamodel on either linux or windows, I get this:

Traceback (most recent call last):
  File ".\asn2dataModel.py", line 27, in <module>
    from .commonPy import configMT, asnParser, cleanupNodes, verify
ImportError: attempted relative import with no known parent package

...is there something I'm missing? Is every usecase which isn't the pre-baked TASTE VM just considered deprecated?

We are generating a Python data model from ASN using a command similar to

asn2dataModel -toPython -o GENERATED_CODE MODEL.asn

One of the outputs is GENERATED_CODE/MODEL_asn.py.
It uses absolute imports for the DV and Stubs modules, e.g.

import DV

from Stubs import (
    myassert, Clean, DataStream, COMMON)

However, this precludes GENERATED_CODE from being used as a self-contained package; in my opinion, it would make more sense to import as

from . import DV

from .Stubs import (
    myassert, Clean, DataStream, COMMON)

What is the intended way of importing and using the MODEL_asn module? Are there specific reasons not to make the imports relative?

While testing the asn2dataModel generated Python files on armv7 architecture, we discovered the discrepancy between the types as defined in the <project_name>_getset.{c, h} files and the Python implementation (i.e. Stubs.py).

All integer values are converted into a long long value and then used to call function from _getset.c file. However, enumerated (i.e. ASN ENUMERATED) and CHOICE values expect to receive an int.
