Python implementation of STEF (Simple Token-Efficient Format)

steflib

Python implementation of STEF: the Simple Token-Efficient Format.

For more details on the format and a full specification, visit stef.nige.tech.

Installation

pip install steflib

Usage

>>> from steflib import stef
>>> from datetime import date
>>> print(stef({"name": "David Bowie", "born": date(1947, 1, 8), "studio_albums": 26}))
name: "David Bowie"
born: 1947-01-08
studio_albums: 26

For streaming output, use the StefWriter directly:

>>> from steflib import StefWriter
>>> from datetime import date
>>> writer = StefWriter()
>>> writer.print({"name": "David Bowie", "born": date(1947, 1, 8)})
>>> writer.print({"name": "Sting", "born": date(1951, 10, 2)})

Plain Python types are mapped to their STEF equivalents automatically. For additional control, typed wrappers are provided - for example, to emit an integer in hexadecimal, or to attach a comment to any value:

>>> from steflib import stef, Integer, Float
>>> print(stef(Integer(255, as_hex=True)))
0xFF
>>> print(stef(Float(3.14, comment="approx")))
3.14 (approx)
