pyiltags 0.1.1

Pure Python implementation of InterlockLedger ILTags standard

PyILTags

Description

PyILTags is a pure Python implementation of the InterlockLedger ILTags TLV encoding.

It implements all tags defined by the standard, each one with proper interfaces to manipulate their data. It can also handle any non standard tag as instances of ILRawTag.

Furthermore, the provided API allows the implementation of new tags from ground up or by reusing one of the existing standard tags with new IDs.

Requirements

This program was developed for Python 3.7 or higher.

It depends on PyILInt 0.2.2 or later to work properly.

Installation

To install this library, you may download the code from github and copy the contents of the directory src into your module's directory.

You can also use pip to install it by running the command:

$ pip install pyiltags

How to use it

This library can be used to create, serialize and deserialize values using the ILTags standard.

This is a very simple example about how to use this library to create, serialize and deserialize a tag:

from io import BytesIO
from pyiltags.standard import ILStandardTagFactory, ILUInt64Tag

# Serialize a tag
tag = ILUInt64Tag(123456)
writer = BytesIO()
tag.serialize(writer)
writer.seek(0)
serialized = writer.read()
print(f'Tag with id {tag.id} and value {tag.value} serialized.')

# Unserialize the tag
reader = BytesIO(serialized)
factory = ILStandardTagFactory()
deserialized_tag = factory.deserialize(reader)
print(
    f'Deserialized tag with id {deserialized_tag.id} and value {deserialized_tag.value}.')

Further information about this library can be found in the source code and in its unit-tests.
