Mint NOIDs using a CLI or API

Project description

noid Python Package

PyPI version PyPI - Python Version example workflow codecov

Installation

Install from PyPI with

pip install noid

or from source with

pip install git+git@github.com:paulkorir/noid.git     # SSH
pip install git+https://github.com/paulkorir/noid.git # HTTPS

CLI Usage

Generating a noid

Use the noid command with no arguments:

noid

There are various options available using -h/--help:

noid -h
usage: noid [-h] [-c CONFIG_FILE] [-V | -d] [-s SCHEME] [-N NAA] [-t TEMPLATE] [-n INDEX] [-v] [noid]

generate nice and opaque identifiers

positional arguments:
  noid                  a noid

optional arguments:
  -h, --help            show this help message and exit
  -c CONFIG_FILE, --config-file CONFIG_FILE
                        path to a config file with a noid section
  -V, --validate        validate the given noid [default: False]
  -d, --check-digit     compute and print the corresponding check digit for the given noid [default: False]
  -s SCHEME, --scheme SCHEME
                        the noid scheme [default: 'ark:/']
  -N NAA, --naa NAA     the name assigning authority (NAA) number [default: ]
  -t TEMPLATE, --template TEMPLATE
                        the template by which to generate noids [default: 'zeeddk']
  -n INDEX, --index INDEX
                        a number for which to generate a valid noid [default: random positive integer]
  -v, --verbose         turn on verbose text [default: False]

Validating a noid

Validate a noid using the -v/--validate flag and pass a noid.

noid -v $(noid) # self-validation

Compute the check digit for a noid

Compute the check digit using -d/--check-digit flag and pass a noid.

noid -d $(noid -t zeee -n 1234) && noid -t zeee -n 1234 && noid -t zeeek -n 1234

The example above prints out the check digit, the full noid without a check digit and the full noid with a check digit.

Options

Specify the NAA

Use the -N/--naa option.

noid --naa 1234

Specify the scheme

Use the -s/--scheme option.

noid --scheme darpa::

Specify a template

Use the -t/--template option.

noid -t zeeddeedeedk

Compute a noid for a value

Use the -n/--index option.

noid -n 42

Using a config file

A simple config file can be defined with the following structure:

# path/to/noid.cnf
[noid]
# start with 'z'; follow with as many 'e' or 'd' as needed; terminate with 'k' for a checkdigit 
template = zeededdek 
scheme = ark:/
naa = 92729
# the above configs will produce noids like so: ark:/92729/fn7Z344v

then use it as follows:

noid -c path/to/noid.cnf

API Usage

You can also use this package's API in your code.

import random

from noid import mint, validate, calculate_check_digit, generate_noid

# with default arguments
noid = mint()

# arguments: template, n, scheme, naa
noid = mint(template='zeedeeedk', n=37, scheme='https://', naa='802938')

# validating a noid
validate(noid) # True/False

# calculate the check digit
calculate_check_digit(noid)

# low-level generate a noid from a mask and number; no check digit is appended
noid = generate_noid('eeddeed', random.randint(100, 1000))

Testing

pip install -r requirements.txt
tox
