Using

From the command line, you can parse serial numbers. If there is an error in parsing, it will loudly complain (sometimes).

$ itksn parse 20UPGMC2291234
Container:
    atlas_project = (enum) atlas_detector b'20'
    system_code = (enum) phaseII_upgrade b'U'
    project_code = (enum) pixel_general b'PG'
    subproject_code = (enum) Module_carrier b'MC'
    identifier = Container:
        module_type = (enum) Linear_triplet_module_carrier b'2'
        module_version = (enum) Quad_v2p1 b'2'
        manufacturer = b'9' (total 1)
        number = b'1234' (total 4)

$ itksn parse 20UPGR90012345
Container:
    atlas_project = (enum) atlas_detector b'20'
    system_code = (enum) phaseII_upgrade b'U'
    project_code = (enum) pixel_general b'PG'
    subproject_code = (enum) Digital_quad_module b'R9'
    identifier = Container:
        FE_chip_version = (enum) RD53A b'0'
        reserved = b'0' (total 1)
        number = b'12345' (total 5)

$ itksn parse 20UPGPD0012345
Container:
    atlas_project = (enum) atlas_detector b'20'
    system_code = (enum) phaseII_upgrade b'U'
    project_code = (enum) pixel_general b'PG'
    subproject_code = (enum) Dual_PCB b'PD'
    identifier = Container:
        FE_chip_version = (enum) RD53A b'0'
        reserved = b'0' (total 1)
        number = b'12345' (total 5)

$ itksn parse 20UPGFW2123456
Container:
    atlas_project = (enum) atlas_detector b'20'
    system_code = (enum) phaseII_upgrade b'U'
    project_code = (enum) pixel_general b'PG'
    subproject_code = (enum) FE_chip_wafer b'FW'
    identifier = Container:
        batch_number = (enum) CROC b'2'
        number = b'123456' (total 6)

If you want to, for example, build the serial number for a front-end chip hex, you can do:

import itksn

number = str(0x20098).zfill(7).encode()
obj = {
    "atlas_project": "atlas_detector",
    "system_code": "phaseII_upgrade",
    "project_code": "pixel_general",
    "subproject_code": "FE_chip",
    "identifier": {"number": number},
}

itksn.core.SerialNumberStruct.build(obj)  # b'20UPGFC0131224'

or even from python, one can parse

import itksn

results = itksn.parse(b"20UPGR90012345")
assert results.atlas_project == "atlas_detector"
assert results.project_code == "pixel"
assert results.identifier.PCB_manufacturer == "Dummy"

or build

from itksn.core import SerialNumberStruct

sn = SerialNumberStruct.build(
    {
        "atlas_project": "atlas_detector",
        "system_code": "phaseII_upgrade",
        "project_code": "pixel",
        "subproject_code": "pixel_general",
        "component_code": "Digital_quad_module",
        "identifier": {
            "FE_chip_version": "RD53A",
            "PCB_manufacturer": "Dummy",
            "number": b"12345",
        },
    }
)
assert sn == b"20UPGR90012345"

Installation

In a fresh virtual environment, you can install from PyPI:

$ python -m pip install itksn

or from the main branch of the GitHub repository:

$ python -m pip install "git+https://github.com/kratsg/itksn.git"

The above is actually cloning and installing directly from the Git repository.

However, if you want to, you can of course also install it directly from the Git repository "locally" by first cloning the repo and then from the top level of it running

$ python -m pip install .

Contributing

As this library is experimental contributions of all forms are welcome.

If you have ideas on how to improve the API or fix a bug please open an Issue.

You are of course also most welcome and encouraged to open PRs.

Developing

To develop, use a virtual environment.

Once the environment is activated, clone the repo from GitHub

git clone [e-mail]:kratsg/itksn.git

and you can use hatch for running tests/development, e.g.

hatch run +py=3.7 dev:test

(Optional) Then setup the Git pre-commit hooks by running

pre-commit install
